Emergency notice system and method

According to the present invention, when an emergency call is made from a mobile terminal to an emergency call receiving organization such as a fire department or police via a mobile communication network, the emergency call in charge is made using information related to the caller such as the location information of the caller. Regarding an emergency call system that can make a call connection with the receiving organization.

For fixed-line telephones, when an emergency call to the fire department (119), police (110), etc. is used to form a call path, the fixed exchange system that forms the call path and the emergency call reception center, which is an emergency call connection, must be in the same administrative district. It becomes. In other words, in the case of a landline phone, the caller can always make a direct call to the appropriate emergency call reception center. On the other hand, an emergency call from a mobile terminal may not arrive at the center of the administrative district (local government) where the accident occurred because the emergency call reception center of the report destination is determined by the base station that received the radio wave of the mobile terminal. The operator on the side of the emergency call reception center confirms the location of the accident (the municipality of the place of transmission), and in the case of an accident in a different administrative district, the operator who received the emergency call transfers it to the emergency call reception center of the responsible administrative district.

Based on FIG. 9, the connection route so far when a report is made from the mobile terminal 101 to the emergency call reception center such as fire department or police will be described. Upon receiving an emergency call from within the area of base station A, the mobile terminal 101 is connected to base station A121, a mobile network exchange, and a carrier network 102 of a fixed network exchange. The carrier network 102 distributes emergency calls to the city A emergency call reception center 105, which is the same administrative district A as the base station A121, based on the information of the base station, and connects the mobile terminal 101 and the emergency call reception center 105. Form.

However, as shown in FIG. 10, in the emergency call from the area 122a of the base station B122 in the administrative district A, the carrier network 102 judges that the emergency call is the emergency call of the administrative district B because the radio wave reception is the base station B122, and the emergency call of the administrative district B The emergency call is distributed to the emergency call reception center 103 in City B, and a call path is formed.

FIG. 11 shows the emergency call transfer procedure described above. In addition, the operator of the emergency call reception center knows that the call is from the mobile terminal 101 by the incoming call display of the reception device 151, and the operator's acceptance procedure is "report disaster content" (in the case of firefighting, "fire". First, check the "ka" emergency ")," name and phone number ", and" current location (disaster location) ". If the location of the disaster is outside the administrative district in charge, the transfer operation is processed by the emergency call reception center in the administrative district in charge. After the operator confirms the content of the report in this way, the operator will transfer it to the emergency call reception center in charge of the accident location, and it will take time from the start of the report to the processing of the operator, and as a result, it will be sent to the department in charge. Has the problem of delaying contact. In addition, since the hold sound is basically not played and the call is silenced during the transfer, the whistleblower may become anxious and disconnect the call, further exacerbating the delay in contact. Here, confirmation of the telephone number is important information for making a connection from the emergency call reception center side due to the possibility of disconnection of the caller.

In addition, when there are many witnesses and emergency calls occur frequently due to the positional relationship shown in Fig. 10, the operator of the emergency call reception center who is not in charge is busy with the transfer operation, and the emergency from the original administrative district is in charge. Response to the report may be delayed. (If the call volume exceeds a certain level, a message will be sent to the caller and the operator will have to wait for connection.) There are several technologies that may be able to deal with such problems as public publications. Since it has been disclosed, it will be described in sequence.

First, the emergency information transmission method using the terminal of the mobile communication system disclosed in Japanese Patent Application Laid-Open No. 2002-92265 uses a mobile terminal provided with a position information acquisition means for acquiring the position information of the current position as the terminal. The method is a step a of acquiring the position information of the current position of the mobile terminal by the position information acquisition means, a step b of the mobile terminal transmitting the position information to the server, and a position information transmitted by the server in the step b. Step c to search for a predetermined emergency contact according to, and step d where the server translates the information including the location information transmitted in step b into the language defined according to the location information, and the server. Includes step e to send the information translated in step d to the emergency contact searched in step c. This method is particularly suitable for mobile communication systems that perform international roaming. The emergency contact information here includes, for example, police institutions, medical institutions, and financial institutions. GPS (Global Positioning System) is an example of location information acquisition means.

According to this first disclosure technology, it is possible to reliably report to the police, etc. in an emergency even overseas, and banks other than banks with which we have a business relationship and banks that have a business alliance with that bank. Even if you have no choice but to do so, you can transfer money from your account to a financial institution near your current location without bothering your relatives in your home country. Second, the emergency support system disclosed in Japanese Patent Application Laid-Open No. 2002-269363 uses the insurance company server of the insurance company and the mobile terminal of the policyholder who can communicate from overseas and has a contract with the insurance company. , The mobile terminal is equipped with a guidance request means for requesting the insurance company server to provide guidance on insurance support for emergencies such as accidents, and the insurance company server is equipped with the details of the emergency and the mobile device. The reception information transmission means for transmitting the reception information for prompting the notification of the current position information of the terminal to the mobile terminal and the countermeasures such as hospitals, police, and local offices are stored in association with the location and the map information of the location. Correspondence destination storage means to search for a suitable countermeasure destination according to the content of the emergency and the current location information of the mobile terminal, and the searched countermeasure destination to the mobile terminal together with the map information of the countermeasure destination A coping destination transmission means for transmitting is provided, and the mobile terminal is provided with a coping destination display means for displaying the received coping destination and map information on the screen.

According to this second disclosure technology, even in the event of an emergency for the insurance policyholder, the mobile terminal connects to the insurance company server via the network and inputs according to the reception information sent from the insurance company server. Just by sending a map of the destination, you can quickly go to the destination even if you are unfamiliar with the land while traveling, especially overseas.

Third, the emergency notification method disclosed in Japanese Patent Application Laid-Open No. 2000-165928 includes a mobile terminal that performs wireless communication, a base station that performs wireless communication with this mobile terminal, and a wireless line control station connected to this base station. In the emergency call system of a mobile terminal equipped with an emergency call reception unit for dealing with emergencies such as fire or failure, the mobile terminal's telephone number and the base station accommodation of the base station that received the transmission signal from this mobile terminal. Receives communication from multiple wireless line control stations and a wireless line control station provided with base station information addition means that adds location information and the wireless line control station code of the wireless line control station connected to this base station. , The most appropriate emergency call reception unit for the wireless line control station based on the mobile phone exchange that sends this to the relay exchange and the wireless line control station code entered in the incoming signal transmitted from the mobile phone exchange. An incoming signal is sent to the relay exchange station that distributes this incoming call signal to the station exchange station connected to, and the emergency call reception unit that is most suitable for the wireless line control station of the wireless line control station code based on the incoming call from the relay exchange station. When the wireless line control station receives an emergency call sent from the mobile terminal via the base station, the telephone number of the mobile terminal and the base station of the base station are provided. The accommodation position information and the wireless line control station code are added, and the relay exchange station is connected to the optimum emergency call reception unit based on this wireless line control station code via the wireless line control station. The configuration is such that an emergency call from the mobile terminal is received by the emergency call reception unit, which is most suitable for the above.

According to this third disclosure technology, it is possible to receive an emergency call from the mobile terminal directly to the optimum reception unit for the wireless line control station that has received the report from the mobile terminal, as in the conventional case. For example, it is possible to take an appropriate response much faster than when an emergency call is received at the central emergency center, which is set up for each prefecture, and then sent to the optimal reception desk.<patcit num="1"><text>Japanese Unexamined Patent Publication No. 2002-92265</text></patcit><patcit num="2"><text>Japanese Unexamined Patent Publication No. 2002-269363</text></patcit><patcit num="3"><text>Japanese Unexamined Patent Publication No. 2000-165928</text></patcit>

<p> The first disclosure technology, the second disclosure technology, and the third disclosure technology have been explained above, but even with these disclosure technologies, the promptness of emergency calls cannot be sufficiently maintained. Certainly, if the first disclosure technology and the second disclosure technology are applied, the whistleblower operates the mobile terminal to send the location information to the server and obtain the information of the emergency call reception center corresponding to the location information. If you can, you can make a direct call to the emergency call reception center in charge of the location of the accident, but the accident may occur before the caller who may be upset due to an emergency makes a call. Not only is it impractical to ask the server for information about the emergency call reception center in charge of the location, but it is also clear that the speed of emergency calls cannot be sufficiently guaranteed. On the contrary, there is a high possibility that the conventional method of transferring from the emergency call reception center that is not in charge of the accident location to the emergency call reception center in charge is quick.</p><p> Next, if the third disclosure technology is applied, an appropriate emergency call reception center will be determined based on the code of the wireless line control station instead of the base station. You can make a direct call to the emergency call reception center in charge. Here, "almost the same" is used because the emergency call system in Fig. 1 determines the appropriate emergency call reception center based on the base station, while the third disclosure technology controls the base station. This is because the appropriate emergency call reception center is determined based on the wireless line control station. In any case, as shown in the emergency call system in Fig. 2, when deciding the emergency call reception center based on the wireless line control station and base station for the critical part of the area in charge of the emergency call reception center, the person in charge is in charge. There may be cases where you are forced to make a call to an emergency call reception center and transfer it. In addition, the number of emergency calls from mobile terminals is increasing year by year, and the ratio of emergency calls exceeds 50%. Today, it is important to accelerate the speed of emergency calls as much as possible, and it is important to take measures to shorten the time to arrive at the site. The solution is required.</p><p> The present invention provides an emergency call system capable of making a call to an appropriate emergency call reception center in charge without burdening the operation of the user and as much as possible without going through the operation of the operator at the emergency call reception center. The purpose is.</p>

<p> (1) In the emergency call method according to the present invention, an emergency call sent from a mobile terminal is sent via a carrier network, and an emergency call reception center's premises exchange forms a communication path between the mobile terminal and the emergency call reception center's communication device. The method is a transmission process in which the mobile terminal sends an emergency call, and a transmission position acquisition process in which the mobile terminal having a function of acquiring the transmission position information of the latitude and longitude acquires the transmission position of the latitude and longitude at the time of transmission. The transmission position transmission process that transmits the acquired transmission position to the premises exchange of the emergency call reception center of the emergency call destination determined by the route determination of the communication equipment of the carrier network, and the premises exchange of the emergency call reception center determined by the route determination The route is determined by the emergency call reception center identification process that specifies the emergency call reception center that has jurisdiction over the position indicated by the transmission position based on the received transmission position, and the emergency call reception center specified in the emergency call reception center identification process. When it is the same as the emergency call reception center determined by, it is specified by the transfer non-call path formation process that forms a call path with the premises exchange in the emergency call reception center determined by the route determination, and the emergency call reception center identification process. If the emergency call reception center is not the same as the emergency call reception center determined by the route decision, the on-site exchange in the emergency call reception center determined by the route determination is the emergency call specified in the emergency call reception center specific process. A transfer process of transferring to the premises exchange of the reception center, and a transfer-enabled call path forming process in which the premises exchange of the emergency call reception center transferred in the transfer process forms a call path with the call device of the emergency call reception center. Is included.</p><p> As described above, in the present invention, the emergency call reception center having jurisdiction over the call position is specified by using the call position at the time of the call of the mobile terminal, and the call device of the specified emergency call reception center and the mobile terminal that made the emergency call are used. Since the communication path is formed, the operator of the emergency call reception center that has jurisdiction over the location information that the user of the mobile terminal was at the time of the call can talk with the user of the mobile terminal, and the operator of the emergency call reception center outside the jurisdiction. It is possible to smoothly inform the operator of the content of the report without waiting for the transfer to the emergency call reception center in the jurisdiction, while the operator is also a user of the mobile terminal located outside the jurisdiction at the time of making a call. This has the effect of eliminating the need to transfer from an emergency call reception center outside the jurisdiction to the emergency call reception center under the jurisdiction.</p><p> The communication equipment of the carrier network corresponds to base stations and various exchanges. The calling device includes not only a telephone but also a device in which software for making a call to a computer is installed. The mobile terminal includes a mobile phone, a PHS, and a PDA, a mobile computer, or a notebook computer in which software for making a call is installed.</p><p> (2) The emergency call method according to the present invention is a communication facility of an emergency call reception center transferred in the transfer process and a carrier network that receives radio waves from a mobile terminal when the emergency call is transmitted, as necessary. It newly includes a manual transfer rule forming step of associating the base station identification information of a certain base station with the sector of the base station in which the mobile terminal was located at the time of sending an emergency call and recording it in a storage means.</p><p> As described above, in the present invention, the identification information of the emergency call reception center transferred in the above step and the base station that received the radio wave from the mobile terminal at the time of transmitting the emergency call and the mobile terminal at the time of transmitting the emergency call at the base station. Since it is recorded in the storage means in association with the sector in which it is located, it is possible to request the emergency call reception center under the jurisdiction using the base station identification information and sector as a key, and not only the base station identification information but also the sector is used. Therefore, even if an emergency call is made from a caller located in an area where the areas of the base stations overlap, the emergency call reception center will be specified based on a sector narrower than the area, which is more accurate. It has the effect of being able to request an emergency call reception center under its jurisdiction. In particular, the emergency call reception center of the appropriate jurisdiction automatically obtained from the transmission position received from the mobile terminal is associated and recorded in the storage means without the operator manually determining the emergency call reception center of the jurisdiction. ..</p><p> The storage means is a memorable one such as a private branch exchange memory or a hard disk, a memorable one such as a communication device memory or a hard disk, or a memorable one such as a private branch exchange or a device other than the telephone device. Is. Of course, the database may be constructed in a device other than the private branch exchange, the computer in which the communication device is constructed, the private branch exchange, and the communication device.</p><p> (3) In the emergency call method according to the present invention, if necessary, the transmission process in which the mobile terminal sends an emergency call and the premises exchange of the emergency call reception center determined by the route determination are the communication devices of the emergency call reception center. A call path formation process that forms a call path, a manual transfer step that transfers to the premises exchange in the emergency call reception center under the jurisdiction determined by the transfer operation of the operator who operates the call device, and a transfer in the manual transfer process. The premises exchange of the emergency call reception center is formed by the call formation process with manual transfer that forms a call path with the call device of the emergency call reception center, and the transfer operation of the operator that the emergency call reception center under the jurisdiction operates the call device. When determined, the base station identification information of the base station, which is the communication equipment of the carrier network that received the radio wave from the mobile terminal at the time of the transmission, the sector in which the mobile terminal was located at the time of transmitting the emergency call, and the operator's It includes a manual transfer rule forming step of associating with the emergency call reception center determined by the transfer operation and recording it in the storage means.</p><p> As described above, in the present invention, the identification information of the emergency call reception center transferred in the manual transfer step and the base station that received the radio wave from the mobile terminal at the time of transmitting the emergency call and the time of transmitting the emergency call at the base station. Since the mobile terminal is associated with the location of the sector and recorded in the storage means, for example, the operator determines the emergency call reception center under the jurisdiction based on the information heard by the operator through a call with the user and makes an emergency call. It has the effect that the communication device and the communication path in the reception center are formed, and the emergency call reception center under the jurisdiction can be requested more accurately.</p><p> (4) The emergency call method according to the present invention is a carrier network communication facility in which the premises exchange of the emergency call reception center determined by route determination receives radio waves from a mobile terminal when sending an emergency call, if necessary. A new process has been added to read out the emergency call reception center that matches the base station identification information of the base station and the sector in which the mobile terminal was located when the emergency call was sent, and to identify the emergency call reception center that has jurisdiction. When the emergency call reception center under the jurisdiction specified in the process is the same as the emergency call reception center determined by the route determination, a call path is formed with the call device in the emergency call reception center determined by the route determination. , If the emergency call reception center under the jurisdiction specified in the process is not the same as the emergency call reception center determined by the route decision, the emergency call within the emergency call reception center determined by the route decision is the emergency call under the specified jurisdiction. It is transferred to the premises exchange of the reception center, and the transferred emergency call reception center premises exchange forms a communication path with the communication device of the emergency call reception center.</p><p> As described above, in the present invention, the function of acquiring the transmission position information of latitude and longitude is particularly provided by requesting the emergency call reception center under the jurisdiction more accurately by using the storage means of (2) or (3). Even if an emergency call is made using a mobile terminal that does not have it, the caller has the effect of being able to make a call with the operator of the emergency call reception center in the jurisdiction without being forwarded.</p><p> (5) The emergency call method according to the present invention newly includes a step in which the storage means provided in each emergency call reception center are renewed to each other as necessary. As described above, in the present invention, the information recorded in the storage means of each emergency call reception center in (2) or (3) is also reflected in the storage means of other emergency call reception centers, so that the information is acquired at each emergency call reception center. Even if the emergency call is made from a position where the communication equipment of the emergency call reception center has never formed a call path in the past, one of the other emergency call reception centers has the call path in the past. If it has been formed, it is included in the shared transfer rule, and has the effect that it can be appropriately transferred using such a transfer rule.</p><p> When updating, for example, the storage means consists of a database server, and the database servers are automatically updated via the network. In addition, the private branch exchange in the emergency call reception center is the private branch exchange in another emergency call reception center. It is also possible to take a configuration of updating by receiving the data read from the storage means from.</p><p> (6) The emergency call method according to the present invention is a communication facility of an emergency call reception center transferred in the transfer process and a carrier network that receives radio waves from a mobile terminal when the emergency call is transmitted, as necessary. In the manual transfer rule forming process in which the base station identification information of a certain base station and the sector about the base station where the mobile terminal was located at the time of sending the emergency call are recorded in the storage means, the mobile terminal sends the emergency call. When the emergency call reception center under the jurisdiction is specified by recording it in the storage means including the time when the emergency call was made, when there are multiple specified emergency call reception centers, it is within the specified time from the current target emergency call transmission time. The process in which the premises exchange in the emergency call reception center determined by route determination determines whether or not there is only one emergency call reception center that has received an emergency call above the first threshold, and within the specified time in the process. If it is determined that there is only one emergency call reception center that has received an emergency call above the first threshold, the premises exchange of the emergency call reception center that is determined to be only one will be the first within the specified time. It forms a communication path between the communication device in the emergency call reception center and the mobile terminal that received an emergency call exceeding the threshold value of.</p><p> As described above, in the present invention, in addition to (4), when the time when the mobile terminal sends an emergency call is added to what is recorded in the storage means, and the emergency call reception center under the jurisdiction is specified, only the time is different. In some cases, multiple call reception centers may be specified, and if the emergency call is included within a predetermined time from the time when the emergency call is currently being sent and is greater than or equal to the first threshold, the emergency call currently being targeted may be specified. When there is only one emergency call reception center related to the time included within the specified time from the outgoing call time, the emergency call reception center and the mobile terminal form a communication path, so the emergency call for the same incident is the same. Utilizing the characteristic of concentrating on the time zone, even if there are multiple candidates for the emergency call reception center under the jurisdiction, the effect that the most probable candidate emergency call reception center and the mobile terminal can form a call path. Has.</p><p> (7) In the emergency call system according to the present invention, the communication equipment of the emergency call reception center forms a communication path between the mobile terminal and the call device of the emergency call reception center via the carrier network for the emergency call transmitted from the mobile terminal. In the system, the mobile terminal is a transmission means for sending an emergency call and a transmission position acquisition means for the mobile terminal having a function of acquiring the transmission position information of the latitude and longitude to acquire the transmission position of the latitude and longitude at the time of transmission. , The emergency call reception center determined by the route determination, including the transmission position transmission means for transmitting the acquired transmission position to the premises exchange of the emergency call reception center of the emergency call destination determined by the route determination of the communication equipment of the carrier network.

If the emergency call reception center specified in the specific process is not the same as the emergency call reception center determined by the route determination, the on-site exchange in the emergency call reception center determined by the route determination will be used in the emergency call reception center identification process. The premises exchange of the emergency call reception center transferred by the transfer means forms a communication path with the call device of the emergency call reception center, including the transfer means for transferring to the premises exchange of the specified emergency call reception center. It includes a means for forming a call path with transfer. In this way, the present invention can be grasped as a system. The outline of these inventions does not enumerate the features essential to the present invention, and subcombinations of these plurality of features can also be inventions.</p>

The same number and step are assigned to the same element throughout all the embodiments, and the elements are the same unless otherwise explained.

(First Embodiment of the present invention) FIG. 1 is a system configuration diagram of an emergency call system according to the present embodiment. In the figure, 1 is a mobile terminal, 2 is a carrier network, 21 and 22 are base stations, 31 and 51 are communication devices, 32 and 52 are private branch exchanges, and 4 and 6 are database search devices. 3 and 5 are emergency call reception centers. 21a is the area of base station 21, and 22a is the area of base station 22. 80 is an administrative division line.

The mobile terminal 1 is a mobile phone, and forms a communication path with a target fixed telephone and other mobile phones via a carrier network 2 including base stations 21 and 22. The mobile terminal 1 is a display unit of a liquid crystal display, a button for inputting a calling number, a calling button, a disconnecting button, a speaker for outputting voice, a microphone for inputting voice, a communication unit for receiving / transmitting radio waves and processing communication, and a caller. It consists of a GPS receiver that acquires the current position of the radio wave and a control unit that controls each component. Here, GPS (global positioning system) is a system that receives radio waves transmitted from artificial satellites and measures the latitude and longitude and altitude of the current position. And the GPS receiver receives the radio wave. Since there are already mobile phones equipped with GPS receivers and they are well-known technologies, detailed explanations will be omitted.

The carrier network 2 is a network owned by a telecommunications carrier and consists of communication equipment such as a switchboard. The communication equipment used in the carrier network differs depending on the carrier, but if it is exemplified by the mobile communication network, it has a base station, a mobile communication exchange and a barrier exchange, and if it is exemplified by a fixed telephone network, it has a subscriber exchange, a relay exchange and the like. It has a barrier exchange. The mobile communication network and the fixed telephone network are connected by an interconnection point (POI: Point Of Interface).

Base stations 21 and 22 are also communication equipment of telecommunications carriers, which are carriers, and communicate with mobile terminal 1 by radio waves and connect with communication equipment (line control station, switch) of carrier network 2 by wire so that they can communicate with each other. ing. The range in which radio waves reach around base stations 21 and 22 is called a zone, and arranging a plurality of base stations 21 and 22 to form a zone to form a service area is called a zone method or a cell method.

The calling devices 31 and 51 are terminals operated by the operator, which are connected to the private branch exchanges 32 and 52 in a communicable manner and enable the caller and the operator to make a call through a headset integrated with headphones and a microphone. Is. The terminal also has a keyboard and a display, so that the operator can input the content of the report from the passerby. Specifically, it is a configuration in which communication devices for connecting to private branch exchanges 32 and 52 are arranged in a general computer. When the private branch exchanges 32 and 52 and the communication devices 31 and 51 are connected by LAN, the communication device becomes a LAN card. Various programs are installed in the call devices 31 and 51, and a function for receiving a call, a function for displaying information related to the caller (caller number, call position information) on the display when receiving a call, and various call contents. It has a function to receive and display the input of the above, a function to make a call, and a function to transmit information related to an emergency call such as information related to a caller and various input contents of a call.

The private branch exchanges 32 and 52 are installed in the emergency call reception centers 3 and 5, and are devices for exchanging and connecting extension telephones and external general telephones (mobile phones and fixed telephones). In the present embodiment, the communication devices 31 and 51 are exchanged and connected to an external general telephone. Specifically, when a connection request is made from the switchboard of the carrier network 2 to the private branch exchanges 32 and 52, the private branch exchanges 32 and 52 call one of the call devices 31 and 51, and the call devices 31 and 51 respond. Then, the response is detected on the exchange side, a communication path is formed, and a call is possible. On the other hand, when the call devices 31 and 51 make a call, the private branch exchanges 32 and 52 detect the call, the private branch exchanges 32 and 52 receive the number, the number is sent to the exchange of the carrier network 2, and the telephone with the corresponding number is called. When the answer is answered, the exchange detects the answer, a call path is formed, and the call becomes possible.

In addition, the private branch exchanges 32 and 52 can request the emergency call reception centers 3 and 5 of the administrative district in charge from the outgoing call position information that can be obtained when an incoming call arrives. As a specific example, if the outgoing location information is longitude or latitude, the address can be obtained from the longitude and latitude, and the emergency call reception centers 3 and 5 of the administrative district in charge can be obtained from the address. For example, "2-2-1 Momochihama, Sawara-ku, Fukuoka City, Fukuoka Prefecture" can be obtained from "latitude: 33 degrees 35 minutes 33.263 seconds, longitude: 130 degrees 21 minutes 17.932 seconds".

Database search devices 4 and 6 are devices that record, read, and search data. In this embodiment, the caller ID, the call location information, and the content of the report are the targets of the data. FIG. 2 is an explanatory diagram of the operating state of the emergency call system according to the present embodiment.

A disaster occurs in City A, and the owner of mobile terminal 1 enters the emergency call phone number (110, 119, 118, etc.) to make a call. The mobile terminal 1 is in the area 22a, and the call is made via the base station 22. At the time of this call, the mobile terminal 1 uses a GPS receiver to transmit transmission position information consisting of latitude and longitude. The carrier network 2 generates a path to the emergency call reception system 3 of a predetermined administrative district for a call, and records the received transmission position information in a database in the network. When an emergency call arrives, the private branch exchange 32 requests the carrier network 2 to notify the caller information related to the emergency call, acquires the caller's caller ID, caller's place information, etc., and sends the database search device 4 to the database search device 4. accumulate. The private branch exchange 32 derives the address from the transmission position information with reference to the database search device 4, and determines whether or not the administrative district is in charge. As a result of the determination, if it is the administrative district in charge, the private branch exchange 32 makes an exchange connection with any of the communication devices 31 of the emergency call reception center 3. If the result of the determination is not the administrative district in charge, the private branch exchange 32 acquires the emergency call reception system 5 of the administrative district in charge with reference to the database search device 4, and processes the automatic transfer to the emergency call reception system 5 of the administrative district in charge. In addition, the private branch exchange 32 transmits the caller information related to the automatic transfer to the database search device 6 via the private branch exchange 52 of the emergency call reception system 5 of the administrative district in charge. By the automatic transfer, a communication path between the communication device 51 and the mobile terminal 1 is formed, and the operator and the caller can talk. At the time of a call, the call device 51 reads the caller information related to the current call from the location information database 6 and displays it on the display unit.

As described above, according to the emergency call system according to the present embodiment, the owner of the mobile phone 1 is in the administrative district A city, and the base station 22 in the area 22a to which the mobile phone 1 belongs is different from the administrative district B city. If the owner enters the emergency call number into mobile phone 1 and makes a call, a pass is established with the emergency call reception system 3 in City B, where the base station 22 is located, and at the same time, the mobile phone is carried when making a call. The premises exchange 32 acquires the caller ID and call location information received by the carrier network 2 from the telephone 1, determines whether or not it is the responsible administrative district by referring to the database search device 4, and considers that it is not the responsible administrative district. Since the call is automatically transferred to the emergency call reception system 5, the caller will be the operator of the administrative district in charge for the first time, and unlike the past, there may be a case where the call is made with an operator who is not in charge of the administrative district. For the operator, even if the other party to call is a caller in the administrative zone in charge and there is a call from a caller outside the administrative zone in charge, the premises exchange 32 automatically makes the call instead of the manual transfer by the operator. Transferring to the premises exchange 52 of the emergency call reception system 5 of the administrative district in charge of the person is saved, and the trouble of transferring to the premises exchange 52, which has been manually performed in the past, is saved.

In the emergency call reception system according to the present embodiment, the private branch exchange 32 determines whether or not the current call is from within the administrative district in charge, but other devices of the emergency call reception system 3 (for example, a database). The search device 4) may make such a determination, and the private branch exchange 32 may automatically transfer the data. However, since the private branch exchange 32 serves as an interface for the emergency call reception system, it is desirable that the private branch exchange 32 be responsible for such a judgment from the viewpoint of quick processing. Further, although the database search device 4 is referred to, it is desirable to expand the information necessary for judgment in the memory of the private branch exchange 32 in the activated state from the same viewpoint of quick processing.

(Second Embodiment of the Invention) The same elements as those of the first embodiment are given the same number, and the elements not separately described are the same. FIG. 3 is a system configuration diagram of the emergency call system according to this embodiment. Unlike the mobile terminal 1 of the first embodiment, the mobile terminal 7 does not have a GPS receiver. Therefore, the transmission position information cannot be transmitted from the mobile terminal 7 to the carrier network 2.

The base stations 21 and 22 assign the caller ID that can uniquely identify the caller to the mobile exchange station that is the communication equipment of the carrier network 2, the base station ID that can uniquely identify the base station, and the base stations 21 and 22. Sector information that can uniquely identify the sector roughly defined by dividing the inscribed angle in the center within the area is transmitted. Normally, the sector configurations of base stations 21 and 22 are 6 sectors and 3 sectors. It is possible to determine in which sector in the area where the base stations 21 and 22 are in the reception range that the caller is located because the antennas of the base stations 21 and 22 have directivity.

In the present embodiment, the current emergency call forwarding procedure will be described for convenience of explanation, and then the emergency call forwarding procedure according to the present invention will be described. Figure 4 is an explanatory diagram of the current emergency call forwarding procedure of the emergency call system.

When the caller is in the administrative district of city A and the mobile terminal 7 is in sector 5 of area 22a of base station 22 located near the administrative division line, the location information is acquired without equipping the GPS receiver. Make an emergency call from the mobile terminal 7 that cannot be used. Upon receiving the call, the base station 22 requests the mobile exchange to be connected for an exchange connection, and transmits the caller ID, the base station ID of the base station, and the sector information to the mobile exchange. The mobile exchange station registers the caller ID, the base station ID of the base station, and sector information, and makes a call setting request to other communication equipment of the carrier network 2. The communication equipment of the carrier network 2 generates a path to the emergency call reception center 3 of the predetermined administrative district in response to the call setting request, and a call path is formed between the mobile terminal 7 and the call device 31 via the private branch exchange 32. To.

The operator talks with the caller to find out the type of report (if 119 is "fire" or "emergency"), name, phone number, and current location (disaster location). When the operator finds out the current position, the operator determines whether or not it is the administrative district in charge, and if it is not the administrative district in charge, the call device 31 is used for the emergency call reception center 5 of the administrative district that has jurisdiction over the current position of the caller. And perform manual transfer. A call path is formed between the caller and the call device 51 of the emergency call reception center 5 of the appropriate administrative district through the communication equipment of the private branch exchange 32 and the carrier network 2, and the caller and the operator of the emergency call reception center 5 make a call. To do. Along with the formation of this call path, the private branch exchange 52 makes a caller ID request and a call location request to the communication equipment and the mobile exchange of the carrier network 2, respectively, and communicates with the caller number from the mobile exchange and the carrier network 2. Receives base station ID and sector information from the equipment.

FIG. 5 is an explanatory diagram of the emergency call forwarding and registration procedure of the emergency call system according to the present embodiment. The figure is the same until the manual transfer by the operator in FIG. 4 (the part above the middle dotted line in FIG. 5 is the same as the corresponding part in FIG. 4), and the different procedures after that are described.

The private branch exchange 32 makes a caller ID request and a call location request (base station and sector information) to the communication equipment and mobile exchange station of the carrier network 2, respectively, and the caller number from the mobile exchange station and the carrier network 2 Receives base station ID and sector information from communication equipment. The private branch exchange 32 registers the received base station ID and sector information and the emergency call reception center of the manual transfer destination in the database 4.

Almost at the same time as the registration in the database, a communication path is formed between the caller and the call device 51 of the emergency call reception center 5 that has been manually transferred, and the caller and the operator of the emergency call reception center 5 make a call. The caller ID, base station, and sector information can be obtained from the communication equipment of the mobile exchange station and the carrier network 2, or the emergency call reception center 3.

FIG. 6 is an explanatory diagram of the emergency call forwarding procedure of the emergency call system according to the present embodiment. The figure is the same up to the call setting request of FIG. 5, and different procedures after that are described. Here, the part above the middle dotted line in FIG. 6 is the same as the corresponding part in FIG. The explanation will be made on the assumption that the data has already been stored in the registration in the database 4 described in FIG. That is, in the present embodiment, the transfer destination rule for manual transfer is stored in the database 4 by the procedure of FIG. 5, and the transfer destination rule is used according to the procedure of FIG.

The private branch exchange 32 makes a caller ID request and a call location request (base station and sector information) to the communication equipment and mobile exchange station of the carrier network 2, respectively, and the caller number from the mobile exchange station and the carrier network 2 Receives base station ID and sector information from communication equipment. The private branch exchange 32 refers to the base station ID and sector information already received for the database 3 as a key. As a result of the reference, the emergency call reception center 5 of the transfer destination is obtained, and the private branch exchange 32 transfers to the emergency call reception center 5. After the transfer, a communication path is formed between the caller and the call device 51 of the emergency call reception center 5 that has been manually transferred, and the caller and the operator of the emergency call reception center 5 make a call. The caller ID and the place of origin are transmitted from the database 4 of the emergency call reception center 3 of the transfer source to the database 6 of the emergency call reception center 5 in accordance with the call. Here, as a result of referring to the database 3, if the corresponding base station ID, sector information and emergency call reception center are not registered by manual transfer by the operator, the emergency call that is currently being processed without transfer is performed. A communication path will be formed in the communication device 31 of the reception center. At this time, the emergency call reception center in charge of the database 3 is stored in advance in the database 3 as the emergency call reception center of the transfer destination, and the base station ID, sector information, and emergency call reception center are stored by manual transfer. In some cases, the emergency call reception center may be updated.

(Other embodiments) [Registration in database]

In the first embodiment, the call path is formed with the emergency call reception center having jurisdiction over the place where the caller is currently located by acquiring the call position information. , The base station ID and sector information can be acquired and registered in the database 4 in association with the emergency call reception center where the call path is formed, as in the second embodiment, and the operator manually transfers the information. Transfer rules are registered without any need, and the time and effort of manual transfer by the operator can be reduced.

[Mutual update of database]

In each of the above embodiments, the registration in the database is registered only for the emergency call reception center to which the operator belongs by manual transfer of the operator, but the registered contents are periodically updated between the emergency call reception centers. You can also (see Figure 7). By doing so, when the registration to the database is completed because it is done at the emergency call reception center with manual transfer, the manual transfer regarding the same base station ID and sector information at other emergency call reception centers will be performed by the operator. Even if it is not implemented by, the emergency call reception center corresponding to the base station ID and sector information is registered in the database, and a call path can be formed to the emergency call reception center of the appropriate administrative district in charge.

Here, it is desirable to register the database even when the transfer is not performed (in this case as well, the case where there was an incoming call in the past and the case where there is no incoming call can be separated). Specifically, the contents registered in the database will be described as an example. Database attributes consist of base station, sector information, transfer source, and transfer destination. Here, the transfer process can be performed even if there is no attribute of the transfer source. It is assumed that all combinations of base station and sector information are stored in the database in advance. Then, for the conditions that have not been received so far, the values of the forwarding source and the forwarding destination are "-" (see FIG. 8 (b) (1)). If a communication path is formed in the communication device of your own emergency call reception center, which is transferred under the conditions that you have received a call so far, the value of the transfer destination will be "x" (Fig. 8 (b) (Fig. 8 (b)). See 2)). If the call is forwarded under the condition of an incoming call, the value of the forwarding destination is the forwarding destination (see Fig. 8 (b) (3)). When the databases are configured in this way, when the databases are updated with each other, there are times when different transfer destinations are associated with the same base station and sector information. This is a case where the same sector area is under the jurisdiction of a plurality of administrative districts, and it means that an emergency such as a fire has occurred in each of the plurality of administrative districts in the past and an emergency call has been made. For such combinations, it is desirable to stop mutual updates of databases and switch from automatic transfer to manual transfer. Therefore, when the forced manual transfer attribute is set in the database and the forced manual transfer flag is set for the combination in which the jurisdiction conflict occurs, the private branch exchange refers to the database and the forced manual transfer flag is set. It is desirable to form a call path with the operator on the premises without transferring, and to transfer manually if necessary.

[Statistical judgment] As shown in FIG. 8 (c), in a database in a certain emergency call reception center, different emergency call reception center communication devices and communication paths may be formed for the same base station and sector information. However, compared to Fig. 8 (b), attributes of outgoing date and time (which may be incoming date and time, transfer date and time, and utterance date and time) are added to this database. It has already been explained that in the past, the destinations that form call paths may differ under the same base station and sector information conditions when the same sector area is under the jurisdiction of multiple administrative districts. .. Normally, it is rare for multiple emergencies to occur within the same sector area, and as shown in Fig. 8 (c), the destinations that form a call path are the same at close call dates and times. This is because when a fire breaks out, multiple different callers make emergency calls about the same fire at the same time. Therefore, when one or more transmissions are made and the combination is registered in the database, and when the base station, sector information, and the destination for forming the call path are the same, a predetermined time (for example, 1 hour. 1 hour). (This is because the number of calls is significantly reduced due to the arrival of fire engines.) It is desirable to determine the destination to form the call path according to the combination. By doing so, if emergency calls outside the administrative district in charge occur frequently, the emergency call reception center can avoid business congestion and will not interfere with the response to emergency calls in the administrative district in charge.

Furthermore, if the destination of the call path within the predetermined time is not yet registered in the database, the base station, sector information and the call path are formed within the predetermined time (for example, 1 hour) from the combination registered at a certain date and time. It is desirable to form a call path with the destination of the combination with the largest ratio even if the ratio is calculated after considering that the combination with the same destination is one. This is because when innumerable emergency calls are made for a certain case and other emergency calls are made a little, if the weight is requested as it is, the weight of the countless emergency calls for a certain case becomes large, and it is related to that certain case. This is to prevent the transfer destination from being always selected as the transfer destination. Here, if all the ratios are the same, manual transfer is used. In the case of Fig. 8 (c), 1 case within 1 hour from "10:31 on March 13, 1990" and 2 within 1 hour from "10:31 on October 3, 1990" There are 4 cases within 1 hour from "23:10 on February 1, 2003" and 3 cases within 1 hour from "21:14 on August 1, 2005", but each is considered to be one. , "From 10:31 on March 13, 1990", 25 [%] may form a communication path with the communication device of your own emergency call reception center, "10:31 on October 3, 1990" 25 [%] may be transferred from to C, and 50 [%] may be transferred from "February 1, 2003 23:10" and "August 1, 2005 21:14" to B. %]. Therefore, in this case, it is automatically transferred to the transfer destination B having the highest ratio of 50 [%]. Here, in the case of automatic transfer, if the maximum ratio is equal to or less than a predetermined threshold value, manual transfer may be used. For example, when the threshold value is set to 80 [%] and the threshold value is shown in FIG. 8 (c), manual transfer is performed.

[Determining the call path formation destination based on the base station, sector information, and distance information] As shown in the second embodiment, it is more appropriate to determine the call path formation destination by the sector that further narrows down the base station. You can talk to the call reception center. Here, in addition to the base station and sector information, the position of the caller is limited based on the distance information from the base station, and the call path formation destination is determined. The distance information from the base station can be roughly obtained from the radio field strength received from the base station by the mobile terminal. Therefore, the radio field strength and distance information obtained by the base station or mobile terminal are transmitted to the private branch exchange that determines the call path formation destination, and the private branch exchange receives the base station, sector information, and distance information (when the received information is the radio wave strength). The distance information is calculated) to determine the destination of the call path. At this time, the radio field strength received from the mobile terminal by the mobile terminal is used, but the radio wave strength received by the base station from the mobile terminal may be used. By doing so, even if the base station, sector information, and time zone are the same, there is a high possibility that a more appropriate emergency call reception center and the caller will form a call path due to the difference in distance information (Fig.). 8 (d)).

[Reflection of erroneous transfer] The emergency call reception system according to each of the above-described embodiments determines that the call automatically transferred by this system is erroneously transferred by the operator of the emergency call reception center at the automatic transfer destination by calling with the caller. If it is possible, by notifying the calling device that the transfer is incorrect, the private branch exchange that has transferred via the private branch exchange that received the transfer will receive the notification and prohibit the re-execution of the transfer. You can also. Specifically, the combination of base station information, sector information, and emergency call reception center used to automatically determine the transfer destination is registered in the prohibited reference list when determining automatic transfer, and the private branch exchange derives the determination of the transfer destination. In such a case, it is introduced to the prohibited reference list at the time of automatic transfer judgment, and when it matches, the transfer is stopped to the transfer destination derived, and the communication device connected to the private branch exchange and the communication path are formed. Further, the private branch exchange can be configured to collect information related to erroneous transfer and display it on the communication device according to the operation of the operator. Further, the private branch exchange can be configured such that the operator correctly sets the information related to the erroneous transfer using the communication device and updates the information of the private branch exchange.

[Caller ID] In each of the above embodiments, the caller ID is first notified to the private branch exchanges 32 and 52, but the caller ID may be notified instead. .. In that case, it is not necessary to make the caller request in the subsequent process. The reason why the caller ID, not the caller ID, is first notified to the private branch exchanges 32 and 52 is that the conventional emergency call operation procedure is regulated as such.

Although the present invention has been described by the above embodiments, the technical scope of the present invention is not limited to the scope described in the embodiments, and various changes or improvements can be made to each of these embodiments. .. Embodiments with such modifications or improvements are also included in the technical scope of the present invention. This is clear from the scope of claims and the means for solving the problems.
