The communication history information consisting of the other party information and the communication content information of the latest one communication with the communication partner is managed in association with the time information of the latest one communication for each communication partner.

【0039】

Further, the communication history management unit 15 manages the communication history information for each communication partner described above together with the information (time information) relating to the time when the one communication is performed.

【0040】

FIG. 3 is a diagram showing an example of communication history information stored in the communication history storage unit 14 by the communication history management unit 15 and sequentially updated.

【0041】

In FIG. 3, the communication history information is formed by associating the communication partner information that identifies the communication partner with the communication content information corresponding to the content of a message or the like received from the communication partner. Information is generated only for the communication partner with whom communication has been performed in the past, and the communication content information is updated every time there is a new communication from the communication partner.

【0042】

Here, the communication partner information includes information such as the telephone number (TEL), handle name (HN), icon, and Bluetooth (R) device address (BD-ADDR) of the communication partner.

【0043】

Further, the communication content information includes information such as a message and an attached file received in communication with the communication partner specified by the communication partner information.

【0044】

Next, in the mobile wireless terminal 10 according to the present invention, an operation when starting communication using the communication history information stored in the communication history storage unit 14 will be described.

【0045】

In this description, for example, in FIG. 1, the mobile wireless terminals 10a, 10b, and 10c each have the same configuration as the mobile wireless terminal 10 shown in FIG. 2, and these mobile wireless terminals 10a, 10b, 10c, respectively. It is assumed that the mobile wireless terminal 10a starts communication when the mobile wireless terminal 10a is used as a master station and the mobile wireless terminals 10b and 10c are used as slave stations for real-time bidirectional communication (chat) by short-range wireless communication.

【0046】

FIG. 4 shows a control sequence at the start of real-time bidirectional communication between mobile wireless terminals 10a, 10b, and 10c under the above premise.

【0047】

According to this sequence, when the mobile wireless terminal 10a starts communication with the mobile wireless terminal 10b (communication partner 1), the mobile wireless terminal 10a sends a BT [abbreviation of Bluetooth (R)] connection request to the mobile wireless terminal 10b to perform mobile radio. Upon receiving this BT connection request, the terminal 10b sends a BT connection response to the mobile wireless terminal 10b.

【0048】

After that, both the mobile wireless terminals 10a and 10b establish a BT connection session and perform connection control to enable short-range wireless communication.

【0049】

In this connection control, the mobile wireless terminal 10a, which is the master station of the chat, identifies the communication partner information (mobile wireless terminal 10b) from the information sent from the mobile wireless terminal 10b at the time of the BT connection response performed before that. Information to be obtained) (step S401).

【0050】

Next, the mobile wireless terminal 10a passes the acquired communication partner information to the communication history management unit 15. The communication history management unit 15 searches for the communication history information stored in the communication history storage unit 14 using the acquired communication partner information as a key (step S402).

【0051】

In this search, the acquired communication partner information and the communication partner information in the communication history information stored in the communication history storage unit 14 are sequentially compared, and it is checked whether or not there is a matching communication partner information. (Step S403).

【0052】

Here, if there is no matching communication partner information (step S403NO), the communication history management unit 15 notifies the short-range wireless communication control unit 16 of the determination result, and the short-range wireless communication control unit 16 notifies the above notification. Based on this, a message exchange session is established with the mobile wireless terminal 10b, which is the communication partner this time, as usual, and communication (message exchange) is started.

【0053】

On the other hand, when the communication partner information that matches the communication partner information acquired from the other party who intends to start communication exists in the communication history information (step S403YES), the communication history management unit 15 sets the matching communication partner information. Is passed to the short-range wireless communication control unit 16.

【0054】

The short-range wireless communication control unit 16 loads the communication content information corresponding to the communication partner information received from the communication history management unit 15 from the communication history storage unit 14 and displays it on the display unit 22 (step S404), and at the same time, this time. A message exchange session is established with the mobile wireless terminal 10b, which is the communication partner, and communication (message exchange) is started from the loaded content information, that is, the old content received in the past from the communication partner this time.

【0055】

Further, when the mobile wireless terminal 10c is also added to the chat members, a message exchange session is established and communication (message exchange) is started through the same procedure as the above-described procedure performed for the mobile wireless terminal 10b.

【0056】

In this case, if the information for identifying the mobile wireless terminal 10c (communication partner information) is stored in the communication history storage unit 14 of the mobile wireless terminal 10a, a message can be exchanged from the old contents received in the past from the mobile wireless terminal 10c. If the information (communication partner information) that identifies the mobile wireless terminal 10c is not stored in the communication history storage unit 14 of the mobile wireless terminal 10a, normal message exchange with the mobile wireless terminal 10c starts. Will be done.

【0057】

Next, in the mobile wireless terminal 10 according to the present invention, an operation when the communication is resumed by using the communication history stored in the communication history storage unit 14 after the communication is interrupted will be described.

【0058】

In this description, for example, in FIG. 1, the mobile wireless terminals 10a, 10b, and 10c each have the same configuration as the mobile wireless terminal 10 shown in FIG. 2, and these mobile wireless terminals 10a, 10b, 10c, respectively. After communication is interrupted while 10c is performing real-time two-way communication (chat) by short-range wireless communication with the mobile wireless terminal 10a as the master station and the mobile wireless terminals 10b and 10c as slave stations, from the mobile wireless terminal 10a. It is premised on the operation of restarting communication.

【0059】

FIG. 5 is a diagram showing a communication restart control sequence after real-time bidirectional communication interruption between mobile wireless terminals 10a, 10b, and 10c under the above premise.

【0060】

According to this sequence, the mobile wireless terminal 10a is in a state where a message exchange session using short-range wireless communication is established with the mobile wireless terminals 10b and 10c which are members of the chat, and the terminals 10b and 10c Messages are exchanged with each other through each short-range wireless communication unit 18.

【0061】

In this state, the mobile wireless terminals 10a, 10b, and 10c are monitored by their respective short-range wireless communication detection units 17 to see if the short-range wireless communication is disconnected.

【0062】

During this period, for example, when the short-range wireless communication detection unit 17 of the mobile wireless terminal 10a detects that the short-range wireless communication connection has been disconnected (step S501), the detection result is the communication history of the mobile wireless terminal 10a. The management unit 15 and the short-range wireless communication control unit 16 are notified.

【0063】

Upon receiving the above notification, the communication history management unit 15 first searches the communication partner information in the communication history information stored in the communication history storage unit 14 using the communication time as a key (step S502), and the communication time is set. The latest communication, that is, the communication partner information regarding the communication partner of the communication immediately before the communication interruption this time is acquired (step S503), and the communication partner information is passed to the short-range wireless communication control unit 16.

【0064】

When the short-range wireless communication control unit 16 receives the communication partner information regarding the immediately preceding communication partner from the communication history management unit 15 after receiving the communication interruption notification from the short-range wireless communication detection unit 17, the short-range wireless communication control unit 16 is based on the communication partner information. , BT connection request and BT connection response are communicated with the immediately preceding communication partner, for example, mobile wireless terminal 10c, via the short-range wireless communication unit 18, and a BT connection session is established.

【0065】

When this BT connection session is established, the communication history management unit 15 communicates with the previous communication obtained by the destination search for the communication partner information in the communication history information stored in the communication history storage unit 14. Using the communication partner information about the other party as a key, the communication history information is further searched (step S504), the communication content information corresponding to the communication partner information (corresponding to the immediately preceding communication partner) is acquired (step S505), and the communication content information is obtained. Is passed to the short-range wireless communication control unit 16.

【0066】

The short-range wireless communication control unit 16 loads the communication content information received from the communication history management unit 15 from the communication history storage unit 14 and displays it on the display unit 22, and then the mobile wireless terminal for which a BT connection session has already been established. A message exchange session is established with the 10c, and communication (message exchange) is started from the loaded communication content information, that is, the past content received from the mobile wireless terminal 10c immediately before the current communication interruption.

【0067】

After that, the mobile wireless terminal 10a communicates stored in the communication history storage unit 14 in order to add another mobile wireless terminal 10b other than the mobile wireless terminal 10c that was communicating immediately before the communication interruption to the members of the chat. The communication partner information and communication content information of the mobile wireless terminal 10b are searched from the history information, a message exchange session is established with the mobile wireless terminal 10b based on the searched communication partner information, and the mobile wireless terminal is established. Communication (message exchange) is started from the past communication contents received before the communication interruption from 10b.

【0068】

Regarding the procedure for resuming communication between the mobile wireless terminal 10a and the mobile wireless terminal 10b, almost the same flow as the above-mentioned procedure performed for the mobile wireless terminal 10c can be applied, but corresponds to step S503 in FIG. It is necessary to change to the procedure of acquiring the "next oldest communication partner information" in the process and further loading the communication content information corresponding to this "next oldest communication partner information" in the process corresponding to step S505.

【0069】

As described above, since the present invention has a function of managing the communication history information including the communication partner information of the communication partner of the real-time two-way communication using the short-range wireless communication function and the communication content information thereof, it has a function of managing the communication history information in real time. Connection control using the above communication history information for a communication partner of two-way communication can be performed.

【0070】

Specifically, for example, as shown in FIG. 4, it is obtained by comparing whether or not the communication partner information acquired from the partner terminal to start communication and the communication partner information in the communication history information match. When the communication partner information and the communication partner information in the communication history information match, real-time two-way communication with the other party terminal is started from the state in which the communication content information corresponding to the matching communication partner information in the communication history information is loaded. Can be done.

【0071】

In this case, if the communication partner has communicated with the communication partner in the past, the user operation at the time of starting the communication with the communication partner is only the first access operation, and the communication is performed from the contents of the communication with the communication partner in the past. You can resume.

【0072】

Further, when it is detected that the communication is interrupted, the communication partner of the immediately preceding communication can be specified from the communication partner information in the communication history information, and the real-time two-way communication can be reconnected with the communication partner. In this case, after the communication is interrupted, the user operation when reconnecting to the communication partner that was communicating immediately before the interruption becomes almost unnecessary. In addition, the present invention is limited to the examples described above and shown in the drawings. Without changing the gist, it can be appropriately modified and implemented without changing the gist.

【0073】

For example, in the above embodiment, only the communication history information storage / update processing function has been described as a function provided in the mobile wireless terminal 10, but the user has a communication history in the mobile wireless terminal 10, for example, in the input / operation unit 21. An instruction operation for erasing the information may be performed, and a means for erasing the corresponding communication history information in the communication history storage unit 14 may be added based on the erasure instruction operation by the user.

【0074】

As for the modified example of the communication history information erasing function, pay attention to the fact that the communication history information for each communication partner is managed together with the information (time information) regarding the time when one communication is performed, as described above. , Even if an automatic erasing means is provided to automatically delete the communication history information corresponding to the communication partner information after a predetermined time has elapsed from the time based on the time information corresponding to each communication partner information in the communication history information. good.

【0075】

Further, in the above embodiment, chat is taken as an example of real-time two-way communication, but the present invention can be applied to communication other than chat.

【0076】

[Effect of the invention]

As described above, according to the present invention, a communication history information management means for managing communication history information including communication partner information for identifying a communication partner and communication content information of the communication partner for each communication partner. When a real-time bidirectional communication is started because a control means for identifying a communication partner from the communication history information managed by the communication history information management means and controlling the connection of the real-time bidirectional communication with the communication partner is provided. Alternatively, when resuming the interrupted real-time two-way communication, the connection to the communication partner at this time can be automated based on the past communication history information of the communication partner, which greatly imposes a burden on the user operation in the connection. Can be reduced to.

【0077】

In particular, in the present invention, a comparison means for comparing whether or not the communication partner information acquired from the partner terminal to start communication and the communication partner information in the communication history information match is provided, and the acquired communication partner information and the communication partner information are provided. If the communication partner information in the communication history information matches, real-time two-way communication with the partner terminal can be started from the state in which the communication content information corresponding to the matching communication partner information in the communication history information is loaded. If the communication partner has communicated in the past, the user operation at the time of starting the communication with the communication partner is only the first access operation, and the communication can be resumed from the contents of the communication with the communication partner in the past.

【0078】

Further, in the present invention, a communication interruption detecting means for detecting the interruption of communication is provided, and when the communication interruption is detected by the communication interruption detecting means, the communication partner of the immediately preceding communication is obtained from the communication partner information in the communication history information. If the configuration is such that real-time bidirectional communication is reconnected to the communication partner after the communication is interrupted, there is almost no need for user operation when reconnecting to the communication partner that was communicating immediately before the interruption. ..
