  In step S204, the control unit 10b disconnects the connection with the receiving-side mobile terminal 20 (specifically, the mobile network 4). When the connection with the transmitting-side mobile terminal 10 is disconnected, the mobile network 4 executes Step S205.

  In step S <b> 205, the mobile network 4 disconnects the connection with the receiving-side mobile terminal 20.

  On the other hand, when the control unit 10b permits the information transmission request, steps S103 to S111 (procedures A, B, C, and D shown in FIG. 4) shown in FIG. 4 are executed.

  According to the present embodiment, the transmission-side mobile terminal 10 transmits the position information and the environment information to the reception-side mobile terminal 20 when the identification information received from the reception-side mobile terminal 20 is stored in the memory 10a. The memory 10a stores identification information for identifying the transmission destination of the position information and the environment information.

  For this reason, if the receiving side mobile terminal 20 has the identification information stored in the memory 10a, the transmitting side mobile terminal 10 receives the position information and the environment information in response to a request from the receiving side mobile terminal 20. It transmits to the side mobile terminal 20. Therefore, it becomes possible to transmit the position information and the environment information to the receiving-side mobile terminal 20 by a request from the receiving-side mobile terminal 20 that is reliable.

  The communication unit 30a outputs the received position information and environment information to the control unit 30c. When receiving the position information and the environment information, the control unit 30c executes step S304.

  In step S304, the control unit 30c associates the position information and the environment information with each other and stores them in the memory 30b. For example, the control unit 30c stores the position information and the environment information in the memory 30b as a database.

  When the position information and the environment information are stored in the memory 30b, the control unit 30c executes Step S305.

  In step S305, the control unit 30c causes the communication unit 30a to execute processing for transmitting the position information and the environment information stored in the memory 30b to the reception-side mobile terminal 20. When receiving the location information and the environment information, the receiving-side mobile terminal 20 executes steps S107 to S111 (procedures C and D shown in FIG. 4) shown in FIG.

  The transmitting-side mobile terminal 10 may transmit the location information and the environment information to the regional information management server 30. In this case, the control unit 30c does not execute step S305 after executing step S304.

  When the user of the receiving-side mobile terminal 20 operates the operation unit 20a and inputs a regional information provision request addressed to the regional information management server 30, the control unit 20b executes step S306.

  In step S306, the control unit 20b causes the communication unit 2b to execute a process of transmitting the area information provision request received by the operation unit 20a to the area information management server 30.

  When the regional information provision request is transmitted to the regional information management server 30, the mobile network 4 executes step S307.

  In step S <b> 307, the mobile network 4 receives the area information provision request, and then transmits the area information provision request to the area information management server 30. When receiving the regional information provision request, the regional information management server 30 executes step S308.

  In step S308, the control unit 30c of the regional information management server 30 reads the position information and the environment information stored in the memory 30b in association with each other, and transmits the read position information and environment information to the reception-side mobile terminal 20. To do.

  For example, the control unit 30c transmits the latest position information and environment information to the receiving-side mobile terminal 20 among the position information and environment information associated with each other stored in the memory 30b.

  When the position information and the environment information are transmitted to the receiving-side mobile terminal 20, the mobile network 4 executes Step S309.

  In step S309, the mobile network 4 receives the position information and environment information, and then transmits the position information and environment information to the receiving-side mobile terminal 20. After receiving the position information and the environment information, the receiving-side mobile terminal 20 executes steps S107 to S111 (procedures C and D shown in FIG. 4) shown in FIG.

  According to the present embodiment, the regional information management server 30 stores the position information and the environment information in the memory 30b in association with each other. The position information and the environment information are collected when the transmission side mobile terminal 10 transmits the position information and the environment information to the reception side mobile terminal 20.

  For this reason, it is possible to automatically create a database of the position information and the environment information only by transmitting the position information and the environment information from the transmission side mobile terminal 10 to the reception side mobile terminal 20.

  Therefore, when the transmitting-side mobile terminal 10 communicates with the regional information management server 30, it becomes possible to accumulate the latest detailed information of the area where the transmitting-side mobile terminal 10 can exist (for example, the area where humans live). In addition, when the receiving side mobile terminal 20 is connected to the regional information management server 30, the mobile terminal can acquire the latest detailed information of each region.

  Even if communication is not possible, for example, when the transmitting mobile terminal is out of service area due to periodic transmission of information via the regional information management server 30 and accumulation of information in the regional information management server 30, the location information history is transferred to the receiving side.
