FIG. 8 is an explanatory diagram for explaining processing when the originating mobile phone 515 sends a communication to the receiving mobile phone 517 via the network 1.
Note that the description of Step 5 ** represents processing on the transmitting side, the description of Step 1 ** represents processing in the network 1, and the description of Step 7 ** represents processing on the receiving side. ing.

<Process of Step 501>
In step 501, an operation for transmitting communication to the receiving-side mobile phone 517 is performed when the caller operates the operation unit 12 of the transmitting-side mobile phone 515.

<Process of Step 502>
Next, in step 502, the caller operates the operation unit 12 to add position information and select whether to send communication.
This is because the sender does not always want to notify the receiver of his / her position because of privacy issues and the like, and it is necessary to make the selection.
However, it is not always necessary to select for each communication, and for example, it may be set for each receiver and stored in the storage unit 16 of the caller-side mobile phone 515.
In addition, the position information may be notified in the standard state, and the position information may be notified when there is no special operation. Conversely, the position information is not notified in the standard state, and the special operation is performed. When there is no location information, the location information may not be notified.
Furthermore, even if the position is notified, it may be possible to select the level to be, for example, the level of a region (city, town, village, nearest station).

<Process of Step 503>
In step 503, when the caller performs an operation for adding the position information and transmitting the communication, the caller-side mobile phone 515 acquires the position information.
Specifically, the control unit 17 controls the position measurement unit 10 to acquire the position of the transmitting-side mobile phone 515 by GPS. In addition, although the position is measured using GPS as an example of the position measuring method, it is not necessarily limited to this.

<Process of Step 504>
In step 504, the control unit 17 controls the communication unit 11 to notify the caller base station 55 of a communication start request signal. Further, in addition to this, the position information of the transmitting-side mobile phone 515 acquired in step 503 is also transmitted.

<Process of Step 101>
In step 55, the originating base station 55 receives the communication start request signal and position information described above. Thereafter, the caller base station 55 mediates communication with the caller mobile phone 515. However, when the caller-side mobile phone 515 moves, the caller-side base station 55 is changed as appropriate.

<Process of Step 102a>
In step 102 a, the server 53 in the cellular phone communication network generates a map screen of the location where the originating mobile phone 515 is located from the location information of the originating mobile phone 515. Here, since the position information on the receiver side is not known, the position on the receiver side is not described on this map screen.

<Process of Step 103a>
In step 103a, the server 53 in the mobile phone communication network communicates with the base station 51 in the network 1 to search for and specify the receiving base station 57 with which the receiving mobile phone 517 can communicate.

<Process of Step 104a>
In step 104a, the receiving base station 57 specified in step 103a transmits a location information request signal to the receiving mobile phone 517 in addition to the communication start request signal. Further, in addition to the position information request signal, the map screen generated in step 102a is also added and transmitted.

<Process of Step 701>
In step 701, the receiving-side mobile phone 517 receives the map screen in addition to the position information request signal.

<Process of Step 702a>
In step 702a, the receiving-side mobile phone 517 displays the map screen of the transmitting-side mobile phone 515 on the display unit 14.

<Process of Step 703a>
In step 703a, the receiver who is the user of the reception-side mobile phone 517 selects whether to notify the caller of the position of the reception-side mobile phone 517, that is, the position of the receiver.
This is because the sender does not always want to notify the receiver of his / her position because of privacy issues and the like, and it is necessary to make the selection.
However, it is not always necessary to select for each communication. For example, it is set for each receiver, and this is stored in the storage unit 16 of the calling-side mobile phone 515 and automatically selected according to the stored contents. You can also.

In addition, the position information may be notified in the standard state, and the position information may be notified when there is no special operation. Conversely, the position information is not notified in the standard state, and the special operation is performed. When there is no location information, the location information may not be notified.
However, it is not always necessary to select for each communication, and for example, it may be set for each receiver and stored in the storage unit 16 of the caller-side mobile phone 515.
Furthermore, even if the position is notified, it may be possible to select the level to be, for example, the level of a region (city, town, village, nearest station).

In addition, the reception-side mobile phone 517 may transmit the location information only when the transmission-side mobile phone 515 notifies the location information.
In addition, referring to the phone book information stored in the storage unit 16, the location information may be automatically notified only when the location information of the other party is registered in advance.
As described above, when the position information is automatically permitted, a notification to the effect that the permission has been automatically made is given. When there is communication that cannot be automatically notified, a warning to that effect is displayed on the display unit 14. Alternatively, the user's judgment is received by voice notification.

<Process of Step 704>
In step 704, when the caller performs an operation for adding the position information and transmitting the communication, the receiving-side mobile phone 517 acquires the position information.
Specifically, the control unit 17 controls the position measurement unit 10 to acquire the position of the reception-side mobile phone 517 by GPS. Here, as an example, the position is measured using GPS, but it is not necessarily limited to this.

<Process of Step 705a>
In step 705 a, the location information of the reception-side mobile phone 517 acquired in step 704 is transmitted to the reception-side base station 57. Note that the location information of the reception-side mobile phone 517 also serves as location-side notification permission information on the reception side. But it is good also as what notifies position information notification permission information separately in addition to position information.

<Process of Step 105a>
In step 105a, the receiving base station 57 receives the position information of the receiving mobile phone 517 transmitted from the receiving mobile phone 517 in step 705a. Then, the position information is transmitted to the cellular phone communication network server 53 that has generated the map screen of the caller cellular phone 515 in step 102a described above.

<Process of Step 106a>
In step 106a, the server 53 in the cellular phone communication network uses the location information of the originating side mobile phone 515 already obtained and the location information of the location side mobile phone 517 obtained in step 105a to determine whether or not the origination side cellular phone 515. And a map screen on which both the mobile phone 517 on the receiving side are entered are generated.
Although details of the method of generating the map screen will be described later, the map screen is generated so as to be displayed using the entire screen range of the display unit 14 of the mobile phone 511.

<Process of Step 107a>
In step 107a, the transmitting base station 55 and the receiving base station 57 transmit the map screen generated in step 106a to the transmitting mobile phone 515 and the receiving mobile phone 517, respectively.

<Process of Step 505>
In step 505, the transmitting mobile phone 515 receives the map graphic transmitted from the transmitting base station 55 and displays it on the display unit 14.

<Process of Step 705>
In step 705, the receiving mobile phone 517 receives the map graphic transmitted from the receiving base station 57 and displays it on the display unit 14.

[Modification Example 1 of Embodiment]

Even if a GPS function is provided, there is a case where notification to a precise position that can be measured by GPS is not required, or a case where notification to a precise position is not desired. In these cases, it is unnecessary to measure the position by GPS. In these cases, the position of the transmitting base station 55 is set as the position of the calling party, and the position of the receiving base station 57 is set as the position of the receiving party.

The base station 51 is given a number for identifying it all, and when the communication from the mobile phone 511 is transmitted / received, the identification number is automatically given to the communication.
If the location information corresponding to the identification number is stored in the cellular phone communication network server 53, a map screen on which both the transmitting base station 55 and the receiving base station 57 are described is easily generated. be able to.
