  When the detection signal is input from the transmission operation detection unit 11, the information reception unit 14 receives a message from the transmission side user in parallel with the latitude / longitude acquisition processing by the latitude / longitude acquisition unit 12 and the request processing by the address request unit 13. The input of (additional information) is accepted. Then, the information receiving unit 14 holds the input message in the main storage unit 102 or the like. For example, a message “Emergency, meeting” is accepted and held. Note that the message input method is not limited to the method of inputting a message directly from the operation unit 106. For example, a message to be transmitted may be selected from a fixed sentence list stored in the auxiliary storage unit 103 or the like or a transmission message history. In addition, the received information is not limited to a text message. For example, in addition to text, image data such as pictographs and photographs, moving image data such as video clips, audio data, and the like may be included.

  The transmission unit 15 reads the correspondence between the latitude / longitude held by the address request unit 13 and the address and the message held by the information reception unit 14 when making a call to the receiving-side mobile phone 20, and the latitude / longitude and address ( The converted position information) and the message are transmitted to the receiving side mobile phone 20 as a call request signal.

  Next, the functional configuration of the receiving-side mobile phone 20 according to the present invention will be described with reference to FIG. FIG. 5 is a block diagram showing a functional configuration of the incoming-side mobile phone 20. As shown in FIG. 5, the receiving-side mobile phone 20 includes a receiving unit (receiving unit) 21, an information display unit (display unit) 22, and a storage unit 23 as functional components.

  The hardware configuration of the incoming side mobile phone 20 is the same as that of the outgoing side mobile phone 10, and each function described with reference to FIG. 5 causes the CPU 101 and the main storage unit 102 shown in FIG. It is realized by operating the communication control unit 104 under the control of the CPU 101 and reading and writing data in the main storage unit 102 and the auxiliary storage unit 103.

  The receiving unit 21 receives the latitude / longitude, address, and message included in the call request signal transmitted from the calling mobile phone 10 when an incoming call is received from the calling mobile phone 10. The message is output to the information display unit 22 and the storage unit 23. Here, the latitude / longitude, address, and message included in the call request signal are included in the call reception request signal when passing through the mobile communication network 30, and are sent to the receiving mobile phone 20.

  The information display unit 22 displays the latitude / longitude, address, and message input by the receiving unit 21 on the display unit 105. For example, when latitude and longitude “139 ° 46′09 ″ 35 ° 40′41 ″”, address “4-1-1 Marunouchi 1-chome, Chiyoda-ku, Tokyo” and message “emergency / meeting” are input later. The incoming call screen as shown in FIG. 9A is displayed. The display of the latitude / longitude, address, and message is not limited to a format that displays the received content as it is. For example, the reception of information may be expressed by an icon. In the incoming call screen shown in FIG. 9A, the reception of the latitude and longitude is represented by an icon “location information”.

  The storage unit 23 stores the latitude / longitude, address, and message input by the reception unit 21 in the auxiliary storage unit 103 and the like. The stored latitude / longitude, address, and message can be redisplayed as part of the incoming call history, for example.

  Next, the operation of the calling-side mobile phone 10 will be described with reference to FIG. FIG. 6 is a flowchart showing the operation of the originating mobile phone 10.

  When the transmission operation by the transmission side user is detected by the transmission operation detection unit 11 (S101, detection step), the latitude and longitude acquisition unit 12 acquires the latitude and longitude on the condition of the detection (S102, acquisition step). Next, the address request unit 13 requests conversion from the acquired latitude / longitude to an address (S103, request step), and acquires the address converted in response to this request.

  In parallel with these acquisition step and request step, the information receiving unit 14 receives a message input (S104, information receiving step).

  Finally, the acquired latitude / longitude, address, and message are transmitted as a transmission request signal to the incoming mobile phone 20 by the transmission unit 15 (S105, transmission step).

  Next, the output operation of the originating mobile phone 10 will be described with reference to FIG. FIG. 7 is a diagram illustrating an example of screen transition when performing a call operation using the caller-side mobile phone 10.

  When inputting the telephone number of the incoming side mobile phone 20, a function button for using the extended function is prepared as shown in FIG. When the function button is pressed after the telephone number is input (the transmission side user performs a transmission operation), an extended function menu as shown in FIG. 7B is displayed. Here, the caller user can select “message” for inputting a message.

  When “Message” is selected in the extended function menu, a menu for selecting whether or not to transmit latitude / longitude and address is displayed. In the example of FIG. 7, after “address transmission” for transmitting an address is selected in FIG. 7C, “current location” for transmitting the address of the current location of the originating mobile phone 10 in FIG. “Positioning” is selected. With these operations, the latitude / longitude is acquired by the latitude / longitude acquisition unit 12, and the request for conversion from the latitude / longitude to the address and acquisition of the converted address are performed by the address request unit 13.

  On the other hand, on the display unit 105, a screen for creating a message as shown in FIG. 7E is displayed immediately after selecting “location measurement” on the screen of FIG. 7D. When “Create Message” is selected here, a message input screen as shown in FIG. 7F is displayed, and the information reception unit 14 performs a request for obtaining latitude / longitude and converting latitude / longitude to address. Message input is accepted. Thereby, the transmission side user can input a message.

  When a message is input and the “confirm button” is pressed, a confirmation screen as shown in FIG. 7G is displayed. The user on the transmission side can confirm the address and message to be transmitted on this confirmation screen. Further, the user on the transmission side can confirm that the latitude and longitude are also transmitted by displaying the “position information” icon. When the “call button” is pressed here, a call process to the callee mobile phone 20 is performed, and the latitude / longitude, address, and message are transmitted.

  Next, a communication procedure between the caller-side mobile phone 10 and the callee-side mobile phone 20 will be described with reference to FIGS. FIG. 8 is a sequence diagram showing a communication procedure between the calling-side mobile phone 10 and the receiving-side mobile phone 20. FIG. 9 is a diagram illustrating an example of a screen displayed on the display unit 105 of each mobile phone when a call is connected between the caller mobile phone 10 and the callee mobile phone 20. Note that the operation (S201) until the latitude / longitude, address, and message are acquired in the calling side mobile phone 10 is as described with reference to FIG.

  First, when the transmission unit 15 of the caller-side mobile phone 10 performs a process of transmitting latitude / longitude, address, and message, a call request signal for requesting a call to the caller base station 31 is transmitted (S202). This call request signal includes latitude / longitude, address and message.

  The caller base station 31 receives the call request signal and transmits a connection request signal to the callee base station 32 (S203). The receiving base station 32 receives the connection request signal and transmits the incoming request signal to the receiving mobile phone 20 (S204). At this time, the latitude / longitude, address, and message included in the transmission request signal are inherited as they are in the connection request signal and the incoming request signal.

  Upon receiving the incoming request signal from the incoming base station 32, the incoming mobile phone 20 transmits a response signal indicating that this incoming request signal has been accepted to the incoming base station 32 (S205). The address and message are displayed on the display unit 105 (S206). For example, a screen as shown in FIG. 9A is displayed.

  After receiving the response signal, the incoming side mobile phone 20 transmits a delivery notification indicating that the incoming request has been accepted to the outgoing side mobile phone 10. This delivery notification is transmitted to the caller mobile phone 10 via the callee base station 32 and the caller base station 31 (S207 and S208) (S209). The calling side mobile phone 10 receives the delivery notification and displays a dialog indicating that the latitude / longitude, address and message have been transmitted to the receiving side mobile phone 20 on the display unit 105 (S210). For example, as shown in FIG. 9B, a message “sent” is displayed. In addition, when the incoming side mobile phone 20 accepts the incoming call request, a call is connected between the outgoing side mobile phone 10 and the incoming side mobile phone 20, and at the same time, the incoming side mobile phone 20 rings and at the same time the outgoing side An RBT (ringback tone) is returned to the mobile phone 10 (S211).

  According to the above-described call system 1, when a call operation is detected by the call operation detection unit 11, the latitude / longitude is acquired by the latitude / longitude acquisition unit 12 and from the acquired latitude / longitude by the address request unit 13. Conversion to an address corresponding to this latitude and longitude is required. In parallel with the process of acquiring the latitude / longitude by the latitude / longitude acquisition unit 12 and the process of requesting the conversion by the address requesting unit 13, the information receiving unit 14 receives a message input by the sender user. Then, at the time of outgoing call to the incoming side mobile phone 20, the address and message converted according to the request are sent to the incoming side mobile phone 20. Thereby, the transmission side user can input a message using the time when the transmission side mobile phone 10 acquires the address and the time when the transmission side mobile phone 10 acquires the latitude and longitude. As a result, it is possible to reduce the waiting time felt by the user on the transmission side when generating information (latitude and longitude and address) related to the position at the time of transmission. In addition, the user of the calling-side mobile phone 10 can efficiently transmit the address and message to the user of the receiving-side mobile phone 20 when making a call.

  Further, according to the above-described call system 1, when an incoming call is received from the calling-side mobile phone 10, the address and message are received by the receiving unit 21 of the receiving-side mobile phone 20, and the user of the receiving-side mobile phone 20 Before responding to the incoming call, the information display unit 22 displays the received address and message. As a result, the user of the incoming side mobile phone 20 can check the address and message transmitted from the outgoing side mobile phone 10 before responding to the incoming call.

  The present invention has been described in detail based on the embodiments. However, the present invention is not limited to the above embodiment. The present invention can be variously modified without departing from the gist thereof.

  In the above-described call system 1, the latitude / longitude acquisition unit 12 acquires the latitude / longitude when the transmission operation is detected by the transmission operation detection unit 11, but the time for acquiring the latitude / longitude is not limited thereto. For example, the latitude / longitude acquisition unit 12 may acquire the latitude / longitude in advance before the transmission operation detection unit 11 detects the transmission operation.

  In the above-described call system 1, the information reception unit 14 has received the message input in parallel with the acquisition of the latitude / longitude by the latitude / longitude acquisition unit 12 and the conversion request by the address request unit 13. It is not limited to this. For example, only the conversion request by the address request unit 13 and the message input reception by the information reception unit 14 may be performed in parallel. Of course, if the latitude / longitude acquisition by the latitude / longitude acquisition unit 12 and the conversion request by the address request unit 13 are received in parallel with the information reception unit 14 receiving a message input, it is used when generating the latitude / longitude and address at the time of transmission. It is more preferable because the waiting time felt by the person can be further shortened.

  In the above-described call system 1, the calling-side mobile phone 10 uses the GPS to acquire the latitude and longitude of the current location where the mobile phone 10 is located, but the method of acquiring the latitude and longitude is not limited to this. For example, a notification radio wave emitted from the transmission-side base station 31 may be received, and the latitude and longitude of the current location may be measured with reference to base station information included in the received notification radio wave. By using not only the GPS but also a radio wave for notification emitted from the transmitting base station 31, it is possible to acquire the latitude and longitude of the current location even when the transmitting mobile phone 10 is in an area where GPS cannot be used. .

  In the above-described call system 1, the address request unit 13 requests the address server 41 to convert latitude and longitude into an address. However, the request destination of this conversion is not limited to this. For example, as shown in FIG. 5, a table in which latitude / longitude and address are associated may be stored in the auxiliary storage unit 103 of the caller-side mobile phone 10. In this case, an address search unit (not shown) provided in the calling-side mobile phone 10 searches for an address instead of the address server 41. Then, the address request unit 13 requests the address search unit to convert latitude and longitude into an address. In addition, when this table is stored in the auxiliary storage unit 103 of the caller-side mobile phone 10, the address request unit 13 itself may search the table and obtain an address corresponding to the latitude and longitude.

  Moreover, in the above-mentioned telephone call system 1, the transmission part 15 also transmitted the latitude longitude, when transmitting an address, However, The information regarding the position transmitted with a message is not limited to this. For example, only the address may be transmitted and the latitude and longitude may not be transmitted. Even in this case, the information receiving unit 14 receives the message input in parallel with the acquisition of the latitude / longitude by the latitude / longitude acquiring unit 12 and the conversion request by the address requesting unit 13. Alternatively, only the latitude and longitude may be transmitted and the address may not be transmitted. For example, when “latitude / longitude transmission” is selected in FIG. 7C, the information reception unit 14 receives an input of a message in parallel with the acquisition of the latitude / longitude by the latitude / longitude acquisition unit 12. In any case, the calling-side user can input a message using the time for which the calling-side mobile phone 10 generates information about the position.
