[Technical field to which the invention belongs]

The present invention relates to a hands-free communication system that connects a hands-free communication device mounted on a vehicle and a mobile phone brought into the vehicle to perform hands-free communication, and a mobile phone used in the system.

【0002】

[Problems to be Solved by the Invention]

Conventionally, a hands-free calling device mounted on a vehicle makes a hands-free calling in a state where a vehicle occupant has a one-to-one wired connection with a mobile phone brought into the vehicle interior. In addition, Bluetooth (registered trademark), which is a type of short-range wireless communication system, is currently discussing a hands-free profile standard for vehicles, but even in that standard, hands-free communication devices and mobile phones are 1 It is premised on a one-to-one wireless connection.

【0003】

However, in recent years, there are many users who own a plurality of mobile phones and use them properly for work or private use. Therefore, if a vehicle occupant brings multiple mobile phones into the passenger compartment, select one of them for hands-free calling while driving, and the other mobile phones will be set to drive mode respectively. It is necessary to perform operations such as turning off the power or turning off the power.

【0004】

It is also possible to wirelessly connect the hands-free calling device and the mobile phone one-to-many by arranging the above-mentioned Bluetooth hands-free profile independently, but the functions become complicated and the software of the profile part becomes It is expected that the scale will increase and compatibility with other models will be lost. Therefore, it is not a very realistic measure.

【0005】

By the way, when a hands-free call is possible while riding, for example, it is assumed that some passengers receive an incoming call from a person who does not want to hear the conversation on the phone. Conventionally, as a countermeasure in such a case, the display of the hands-free calling device is referred to to confirm who the caller is, and the call is not received and is automatically left in the message mode. There was only. However, such a response is obviously unnatural, and there are problems such as giving a feeling of distrust to the passengers.

【0006】

The present invention has been made in view of the above circumstances, and the first object thereof is to easily handle each mobile phone when a plurality of mobile phones are brought into a vehicle to make a hands-free call. The purpose is to provide a hands-free calling system capable of providing a mobile phone used for the system.

【0007】

A second object of the present invention is a hands-free calling system capable of smoothly avoiding a call when an incoming call is received from a person who does not want the passenger to hear the conversation on the phone. The purpose is to provide mobile phones used in the system.

【0008】

[Means for solving problems]

According to the hands-free calling system according to claim 1, when any one of the plurality of mobile phones becomes capable of hands-free calling via the hands-free calling device, the mobile phone is used as a short-range wireless communication means. By performing wireless communication with other mobile phones via the above, it is set so that calls made through other mobile phones cannot be performed.

【0009】

That is, even if the occupants of the vehicle bring a plurality of mobile phones into the vehicle, they do not have to make settings for disabling the mobile phones that are not the target of the hands-free call via the hands-free call device. , The setting is collectively performed by the mobile phone that is the target of the hands-free call. Therefore, convenience can be improved.

【0010】

According to the hands-free calling system according to claim 2, the mobile phone in a state where hands-free calling is possible sets the other mobile phones to the drive mode. That is, the person who made a call to the mobile phone set in the drive mode recognizes that the call cannot be made on the phone by the announcement, so that the call at that time is abandoned or the recipient other than the recipient. If you know your phone number, you will try to make a call with another phone number. Therefore, it is possible to reliably make only hands-free calls.

【0011】

According to the hands-free calling system according to claim 3, the mobile phone in a state where hands-free calling is possible sets the other mobile phones to the call transfer mode. Therefore, if the incoming call is transferred to the mobile phone that is the target of the hands-free call, the call can be made at that time, so that the hands-free call can be surely made even if there is an incoming call on any of the mobile phones. it can.

【0012】

According to the hands-free calling system according to claim 4, the mobile phone that is ready for hands-free calling is selected from any of the caller numbers existing in the list of caller numbers that are prohibited from hands-free calling. Set so that hands-free calling is disabled when there is an incoming call. Therefore, if an incoming call is expected from a caller who does not want the passengers in the vehicle to hear the hands-free call, registering the caller number in the list will allow the call to be avoided smoothly. it can.

【0013】

According to the hands-free calling system according to claim 5, the list holds information on passengers who prohibit hands-free calling for each caller ID. Then, if the passenger's mobile phone is equipped with the same type of short-range wireless communication means, the mobile phone that makes a hands-free call performs wireless communication with the passenger's mobile phone via the short-range wireless communication means. It is set so that hands-free calling is disabled when there is an incoming call from a caller ID corresponding to the passenger by obtaining the passenger's information.

【0014】

That is, the passenger who does not want to hear the hands-free call is generally determined relatively by the relationship with the caller. When the passenger's mobile phone is provided with the same type of short-range wireless communication means, information for identifying the passenger can be easily obtained by short-range wireless communication.

【0015】

According to the hands-free calling system according to claim 6, the mobile phone makes a hands-free call when there is an incoming call from any of the caller IDs in the list of caller numbers for which hands-free calls are prohibited. Set so that it is impossible. Therefore, if an incoming call is expected from a caller who does not want the passengers in the vehicle to hear the hands-free call, registering the caller number in the list will allow the call to be avoided smoothly. it can.

【0016】

According to the hands-free calling system according to claim 7, the mobile phone disables the call by setting itself in the drive mode. That is, the person who makes a call to the mobile phone recognizes that the phone cannot make a call by the announcement, and therefore gives up the call at that time. Therefore, hands-free calling can be reliably disabled.

【0017】

According to the hands-free calling system according to claim 8, the mobile phone disables the call by setting itself in the message mode. Therefore, the person who made a call to the mobile phone recognizes that the telephone cannot make a call by the announcement on the network side and sends a message as necessary, so that the call at that time is abandoned. .. Therefore, even in this case, the hands-free call can be surely disabled.

【0018】

According to the hands-free calling system according to claim 9, the list holds information on passengers who prohibit hands-free calling for each caller ID. Then, if the passenger's mobile phone is equipped with the same type of short-range wireless communication means, the mobile phone that makes a hands-free call performs wireless communication with the passenger's mobile phone via the short-range wireless communication means. It is set so that hands-free calling is disabled when there is an incoming call from a caller ID corresponding to the passenger by obtaining the passenger's information.

【0019】

That is, the passenger who does not want to hear the hands-free call is generally determined relatively by the relationship with the caller. When the passenger's mobile phone is provided with the same type of short-range wireless communication means, information for identifying the passenger can be easily obtained by short-range wireless communication.

【0020】

BEST MODE FOR CARRYING OUT THE INVENTION

(First Example) Hereinafter, the first embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 shows the overall configuration of a hands-free calling system. The hands-free calling system 1 includes a hands-free device 3 mounted on the vehicle 2 and, for example, three mobile phones 4 (A), 5 (B), 6 (C) that the occupant of the vehicle 2 brings into the vehicle interior. Consists of.

【0021】

FIG. 2 shows a functional block diagram of the electrical configuration of the hands-free device 3 and the mobile phone 4 as a representative. The hands-free device 3 is configured by electrically connecting an operation switch 8 including a hook switch, a voice switching unit 9, and a Bluetooth communication unit (short-range wireless communication means) 10 to a control unit 7 mainly composed of a microcomputer. Has been done. The antenna 10a is connected to the Bluetooth communication unit 10. The operation switch 8 is provided with various keys for starting, ending, or holding a call. A microphone 11 for transmitting and a speaker 12 for receiving are connected to the voice switching unit 9.

【0022】

In the mobile phone 4, the telephone communication unit 14, the voice switching unit 15, the display 16, and the keypad 17 that perform processing related to telephone communication are connected to the control unit 13 mainly composed of a microcomputer, and the Bluetooth communication unit is connected. (Short-range wireless communication means) 18 is electrically connected and configured. A microphone 19 and a speaker 20 are connected to the voice switching unit 15. Antennas 14a and 18a are connected to the telephone communication unit 14 and the Bluetooth communication unit 18, respectively. The Bluetooth communication unit 18 performs short-range wireless communication conforming to the Bluetooth communication standard.

【0023】

In the above configuration, the mobile phone 4 can be wirelessly connected to a base station (not shown) and can communicate with the other party's mobile phone 20 or the like through the telephone network 19 connected to the base station. The mode of the call by the mobile phone 4 includes a handset call process in which the mobile phone 1 makes a call and a hands-free call process in which the hand-free device 3 is used, and these are selectively implemented. It is configured to be able to.

【0024】

Further, the other mobile phones 5 and 6 also have basically the same configuration as the above, and as shown in FIG. 1, each has a Bluetooth communication unit (short-range wireless communication means) 21 and 22. Then, the hands-free device 3 and the mobile phones 4 to 6 form a piconet for Bluetooth communication. In this case, the mobile phone 4 is set as the master and the other devices are set as the slaves. To do.

【0025】

Next, the operation of this embodiment will be described with reference to FIG. FIG. 3 is a sequence showing a schematic processing content of Bluetooth communication performed between the hands-free device 3 and the mobile phones 4 to 6. The Bluetooth communication unit 18 of the mobile phone 4 which is the master searches for what kind of function a slave exists in the vicinity in the inquiry of the synchronization establishment phase. That is, the hands-free devices 3, mobile phones 5, and 6 that received the IQ packets transmitted by the mobile phone 4 side have the Bluetooth addresses assigned to their own Bluetooth communication units 10, 21, and 22, and what kind of functions they have. A device class or the like indicating whether or not the device (device) is possessed is returned (response) by an FHS packet. Therefore, the mobile phone 4 recognizes that the hands-free device 3 and the mobile phones 5 and 6 are present in the vicinity of the mobile phone 4 by performing this search.

【0026】

Then, the Bluetooth communication unit 18 of the mobile phone 4 shifts to the communication connection phase (connection, data transfer), and the function is set for each slave. That is, a setting for executing a hands-free call is made with the hands-free device 3, and a setting is made so that voice data can be transmitted.

【0027】

Further, the mobile phone 4 gives a command to the other mobile phones 5 and 6 to set themselves in the drive mode. If you make a call to mobile phones 5 and 6 set to drive mode, you will hear a message such as "I am driving a car now. I'm sorry, please call back later."

【0028】

After that, the occupants of the vehicle 2 can make a call only through the mobile phone 4. And there is no particular need to maintain a Bluetooth piconet between mobile phones 5 and 6. Therefore, the mobile phone 4 disconnects the communication link with them so that the slave mobile phones 5 and 6 are separated from the piconet.

【0029】

As described above, according to the present embodiment, when the mobile phone 4 becomes capable of hands-free calling via the hands-free calling device 3 mounted on the vehicle 2, the mobile phone 4 becomes the other mobile phones 5 and 6. Mobile phones 4 and 5 are set to drive mode by performing wireless communication between them via Bluetooth communication units 18, 21 and 22. Therefore, even if the occupants of the vehicle 2 bring three mobile phones 4 to 6 into the vehicle 3, they cannot make a call to the mobile phones 5 and 6 which are not the targets of the hands-free call via the hands-free call device 3. Even if the settings are not made one by one, the settings are automatically made by the mobile phone 4 that is the target of the hands-free call, so that the convenience can be improved.

【0030】

Then, the person who made a call to the mobile phones 5 and 6 set in the drive mode recognizes that the call cannot be made on those phones 5 and 6 by the announcement, so should the call be abandoned at that time? Or, if you know the phone number of the mobile phone 4, you will try to make a call using that phone number. Therefore, it becomes possible to reliably make only hands-free calls. If the connection between the mobile phone 4 and the hands-free device 3 is disconnected in a normal procedure, the drive mode set in the mobile phones 5 and 6 is canceled.

【0031】

(Second Example) FIGS. 4 and 5 show a second embodiment of the present invention. FIG. 4 is a functional block diagram showing the configuration of a hands-free calling system. The hands-free calling system 31 is composed of a hands-free device 33 installed inside the vehicle 32 and a mobile phone 34.

【0032】

The hands-free device 33 is configured by electrically connecting an operation switch 36 including a hook switch, a voice switching unit 37, and a Bluetooth communication unit (short-range wireless communication means) 38 to a control unit 35 mainly composed of a microcomputer. Has been done. The antenna 38a is connected to the Bluetooth communication unit 38. The Bluetooth communication unit 38 performs short-range wireless communication conforming to the Bluetooth communication standard, and in this case, it is assumed that the Bluetooth communication unit 38 is set as a slave. The operation switch 36 is provided with various keys for starting, ending, or holding a call. A microphone 39 for transmitting and a speaker 40 for receiving are connected to the voice switching unit 37.

【0033】

In the mobile phone 34, a telephone communication unit 42, a voice switching unit 43, a display 44, and a keypad 45 that perform processing related to telephone communication are connected to a control unit 41 mainly composed of a microcomputer, and a Bluetooth communication unit. (Short-range wireless communication means) 46 is electrically connected and configured. A microphone 47 and a speaker 48 are connected to the voice switching unit 43. Antennas 42a and 46a are connected to the telephone communication unit 42 and the Bluetooth communication unit 46, respectively. In this case, the Bluetooth communication unit 46 is assumed to be set as the master.

【0034】

In the above configuration, the mobile phone 34 can be wirelessly connected to a base station (not shown) and can communicate with the other party's mobile phone 50 or the like through the telephone network 49 connected to the base station. The mode of the call by the mobile phone 34 includes a handset call process in which the mobile phone 34 makes a call and a hands-free call process in which the hand-free device 33 makes a call, and these are selectively implemented. It is configured to be able to.

【0035】

The control unit 41 of the mobile phone 34 has a built-in memory 41a, and the call prohibition list 51 is stored in the memory 41a. The call prohibition list 51 shows, for example, when a user of the mobile phone 34 performs hands-free call processing in the passenger compartment of the vehicle 32, and an incoming call is expected from a person who does not want the passenger to hear the contents of the conversation. , The caller ID of the other party, for example, "090-XXXXX-XXXXXX" is registered in advance.

【0036】

Next, the operation of the second embodiment will be described with reference to FIG. The Bluetooth communication unit 46 of the mobile phone 34, which is the master, searches for what kind of function a slave exists in the vicinity in the inquiry of the synchronization establishment phase. That is, the hands-free device 33 that has received the IQ packet transmitted by the mobile phone 34 side is a device that indicates the Bluetooth address assigned to its own Bluetooth communication unit 38 and what kind of function the device (device) has. Reply (reply) the class etc. by FHS packet. Therefore, the mobile phone 34 recognizes that the hands-free device 33 exists in the vicinity of itself by performing this search.

【0037】

Then, the mobile phone 34 shifts to the communication connection phase (connection, data transfer), and the function is set for each slave. That is, a setting for executing a hands-free call is made with the hands-free device 33 so that voice data can be transmitted.

【0038】

FIG. 5 is a flowchart showing the contents of processing mainly performed when an incoming call occurs by the control unit 41 of the mobile phone 34. The control unit 41 waits until the mobile phone 34 receives an incoming call (step A1), and when the incoming call occurs (YES), is the caller ID registered in the call prohibition list 51 of the memory 41a? Determine if not (step A2).

【0039】

In step A2, if the caller ID is not registered in the call prohibition list 51 (NO), the control unit 41 performs hands-free communication processing (step A3). That is, voice data is transmitted to and from the hands-free device 33 via the Bluetooth communication units 46 and 38. On the other hand, if the caller ID is, for example, "090-XXXXX-XXXXXX" and is registered in the call prohibition list 51 (step A2, "YES"), the control unit 41 drives itself into the drive mode. By setting to, hands-free communication is prohibited (step A4). Therefore, in this case, the caller will hear a message such as "I am driving a car now. I'm sorry, please call back later." And will give up the call at that point.

【0040】

As described above, according to the second embodiment, when the mobile phone 34 receives an incoming call from any of the caller IDs existing in the call prohibition list 51, the mobile phone 34 sets itself to the drive mode to make a hands-free call. Make it impossible. Therefore, if an incoming call is expected from a caller who does not want the passengers of the vehicle 32 to hear the hands-free call, registering the caller ID in the call prohibition list 51 makes the call smooth. Can be avoided.

【0041】

Then, the caller recognizes that the telephone 34 cannot make a call by the announcement of the mobile phone 34, and therefore gives up the call at that time. Therefore, hands-free calling can be reliably disabled. The set drive mode is canceled by an incoming call with a calling number not registered in the call prohibition list 51.

【0042】

(Third Example) FIGS. 6 to 9 (and FIG. 4) show a third embodiment of the present invention, and the same parts as those of the second embodiment are designated by the same reference numerals and the description thereof will be omitted. Only the different parts will be described below. In the third embodiment, it is assumed that there are a plurality of occupants in the vehicle 32, and each of them has their own mobile phones 34'(A), 52 (B), 53 (C).

【0043】

In the mobile phone 34', the call prohibition list 51 stored in the memory 41a in the second embodiment is replaced with the call prohibition list 54. As shown in FIG. 7, the call prohibition list 54 of the third embodiment shows a person who may ride in the vehicle 32 (for example, a mobile phone number of X, Y, Z) and each person X, Y, Z. In response to this, the user of the mobile phone 34'registers in advance the telephone number of the other party who does not want to hear the contents of the call. Further, as will be described later, the call prohibition list 54 is provided with an area for storing a flag set according to whether or not X, Y, and Z are actually on the vehicle 32.

【0044】

The configurations of the mobile phones 52 and 53 are basically the same as those of the mobile phones 34', but the call prohibition list 54 is not retained. Further, it is assumed that the Bluetooth communication units (short-range wireless communication means) 55 and 56 built in each are set as slaves. The above hands-free device 33 and mobile phones 34'52, 53 constitute the hands-free calling system 57.

【0045】

Next, the operation of the third embodiment will be described with reference to FIGS. 8 and 9. FIG. 8 is a flowchart showing the control contents centering on the control unit 41A and the Bluetooth communication unit 46 of the mobile phone 34'. Similar to the second embodiment, the Bluetooth communication unit 46 of the mobile phone 34', which is the master, searches for what kind of function a slave exists in the vicinity in the "inquiry" of the synchronization establishment phase (step). B1, see Figure 9). Then, the mobile phone 34'recognizes that the hands-free device 33 and the mobile phones 52, 53 exist in the vicinity of the mobile phone 34'by performing this search.

【0046】

Then, the control unit 41A and the Bluetooth communication unit 46 shift to the communication connection phase and set so that hands-free communication with the hands-free device 33 is possible (step B2, "YES" step B4). , Get the phone number assigned to each phone 52,53 with the mobile phones 52,53 (step B5, "YES" step B6, see Figure 9).

【0047】

If the hands-free device 33 does not exist (step B2, "NO"), the mobile phone 34'is used alone to make a handset call (step B3). If the other telephones 52 and 53 do not exist (step B5, "NO"), the process proceeds to step B9, which will be described later.

【0048】

The control unit 41A determines whether or not the numbers of the mobile phones 52 and 53 obtained in step B6 correspond to those registered in the call prohibition list 54 (step B7). In this case, for example, when a number corresponding to X in the call prohibition list 54 is obtained, the on-board flag corresponding to the X is set as shown in FIG. 7 (step B8). Then, the process proceeds to step B9 and waits until an incoming call occurs on the mobile phone 34'. Further, in step B7, even if there is no corresponding number in the call prohibition list 54 (NO), the process proceeds to step B9 without setting the on-board flag.

【0049】

When an incoming call occurs on the mobile phone 34'(step B9, "YES"), the control unit 41A determines whether or not the called number is subject to call prohibition (step B10). That is, in this case, if the call prohibition target number 090-××××-×××× corresponding to passenger X is (YES), the control unit 41A sets itself to the drive mode (step). B12). If the number is not a call prohibition target number (NO), hands-free call processing is performed via the hands-free device 33 (step B11).

【0050】

As described above, according to the third embodiment, the mobile phone 34'holds the information of the passenger who prohibits hands-free calling for each caller ID in the call prohibition list 54, and the passenger of the vehicle 32 Obtain each phone number from mobile phones 52,53 via the Bluetooth communication units 46, 55, 56. Then, when there is an incoming call from the caller ID corresponding to the passenger, the user is set to the drive mode so that hands-free calling is disabled. That is, the passengers who do not want to hear the hands-free call are generally determined relatively by the relationship with the caller. Therefore, with such a configuration, it is possible to appropriately avoid the call depending on the relationship between the passenger and the caller. The set drive mode is canceled by an incoming call with a calling number not registered in the call prohibition list 54.

【0051】

The present invention is not limited to the examples described above and shown in the drawings, and the following modifications or extensions are possible. The communication connection between the mobile phone and the hands-free device does not necessarily have to be made by Bluetooth, but may be made by a wired method. The short-range wireless communication means is not limited to Bluetooth, and any short-range wireless communication means that can perform wireless communication at a short distance of several meters to 100 m is sufficient. In the first embodiment, after the mobile phone 4 sets the mobile phones 5 and 6 to the drive mode, the mobile phone 4 may be set to make a hands-free call with the hands-free device 3. Further, after setting the mobile phones 5 and 6 to the drive mode, the mobile phones may be made to stand by in the constant power consumption mode.

【0052】

Further, the mobile phones 5 and 6 may be set to the incoming call transfer mode, and when an incoming call is received, it may be transferred to the mobile phone 4. With such a configuration, even if there is an incoming call to the mobile phones 5 and 6, it is possible to reliably make a call via the mobile phone 4 at that time. Further, the mobile phones 5 and 6 may be set to the message mode, or the power may be turned off. There may be two or four or more mobile phones. The configuration of the first embodiment may be combined with the configurations of the second and third embodiments. However, when combining the configurations of the third embodiment, it is premised that a mobile phone held by a passenger (another person) exists separately.

【0053】

In the second embodiment, the mobile phone 34 may reject the incoming call. In the second embodiment, when the communication connection between the hands-free device 33 and the mobile phone 34 is made by a wired method, the Bluetooth communication units 46 and 36 are unnecessary. In the third embodiment, the mobile phone 34'may reject incoming calls. In the third embodiment, the mobile phone 34'may be set to the message mode. In the third embodiment, there may be two or four or more mobile phones. When a plurality of mobile phones owned by the occupants (drivers) of the vehicle 32 are brought into the passenger compartment, the configuration of the third embodiment may be combined with the configuration of the first embodiment.
