  The wireless communication terminal 1 that has received the request returns the information of the base station 2 to which it belongs to the information exchange server 4 to the information exchange server 4 (step S003).

  When the base station information is included in the message (first report), the acquisition operation of the base station 2 and the response operation of the wireless communication terminal 1 by the information exchange server 4 can be omitted. It is also possible to adopt a form in which the information exchange server 4 makes an inquiry to the location management server that manages the location of each wireless communication terminal in the mobile communication network, instead of making an inquiry to the wireless communication terminal 1.

  Next, the information exchange server 4 requests the base station 2 indicated by the wireless communication terminal 1 for information on all the wireless communication terminals whose positions are registered in the base station (step S004).

  Upon receiving the request, the base station 2 replies to the information exchange server 4 with all the wireless communication terminals (in this case, wireless communication terminals 3) registered in the base station (step S005). .

  The information exchange server 4 creates group information that groups the replied wireless communication terminals as a group, and registers the group information in the group information storage area 46 (step S006).

  Next, the information exchange server 4 uses the group information to transmit the cooperation request message described above to the message (first report) transmitted in step S001 to the wireless communication terminal 3 whose location is registered in the base station 2. And a message transmission method and the like are attached (step S007).

  The user of the wireless communication terminal 3 that has received the above message (first report) or the like, based on the received message (first report) or the like, performs evacuation behavior, rescue activities of the user of the wireless communication terminal 1 or further information collection activities. Etc. The user of the wireless communication terminal 3 may send a message (second report) when providing new information to the group members, such as on-site status confirmation results, evacuation routes and evacuation site conditions. Yes (step S008).

  When the new message is received, the information exchange server 4 confirms that the wireless communication terminal 3 belongs to the existing group using the group information, and transmits the new message to the wireless communication terminal 1 whose location is registered in the base station 2. The message (second report) transmitted in step S008 is transmitted (step S009).

  Similarly, as shown in FIG. 4, information regarding an emergency situation notified by a message (first report) is exchanged between group members. For example, as shown in FIG. 3, as a second report, a message “National road is congested. Please detour.” Is distributed to the users of wireless communication terminals in the vicinity. It becomes possible to prompt the change of the evacuation route. In addition, as a third report, a message “Injured is out. Please support me.” Is distributed to users of wireless communication terminals in the vicinity, so that ambulances can be called and other users can support them. Can be called.

  Delivery of messages to group members as described above is continued for a certain period of time, such as a group release operation performed by a system administrator (an administrator of the information exchange server 4).

  As described above, according to the present embodiment, information regarding disasters, incidents, and accidents can be exchanged between arbitrary users belonging to the same base station using the base station information as if an emergency contact network was formed. Can be used to help victims and prevent damage from spreading.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and further modifications, substitutions, and adjustments may be made without departing from the basic technical idea of the present invention. Can be added. For example, in the above-described embodiment, the information exchange in the event of an accident or disaster has been described as an example. However, it is also used as a means for propagating word-of-mouth information to nearby users in events closely related to the area. It is possible.

  In the above-described embodiment, the base station information is used as the position information of the wireless communication terminal that has transmitted the message first. However, the wireless communication terminal has a GPS (Global Positioning System) function. In this case, position information measured by this GPS function can be used.

  Further, in the above-described embodiment, it has been described that the group is formed by the wireless communication terminals belonging to the same base station (cell) as the wireless communication terminal that transmitted the message first, but the geographical range for forming the group is It can be changed as appropriate according to the content of the message. For example, when it is necessary to call a user in a wide area for cooperation or to evacuate, a wireless communication base station located in the service range of a plurality of adjacent base stations (cells) can be targeted. Conversely, a group can also be created for wireless communication terminals belonging to one sector of a certain base station (cell).

  Furthermore, when detailed location information can be obtained from each wireless communication terminal by the GPS function or the like, a group of wireless communication terminals located nearby is created using the latitude and longitude information obtained by the GPS function. Is also possible. If the wireless communication terminal is equipped with a GPS function, position information measured by the GPS function at the time of message transmission may be attached.

  In the above-described embodiment, the wireless communication terminals constituting the group are not reviewed. However, the wireless communication terminals constituting the group may be appropriately reviewed. For example, if the affected area is moving, expanding, or contracting in a certain direction, or if a criminal is running away, the wireless communication terminal that sent the second and third messages By recreating a group based on the position of, it is possible to call attention to a user who does not belong to an existing group.

  In the above-described embodiment, the telephone number and the mail address of the wireless communication terminals belonging to the group are registered. However, it is also possible to register a user ID created separately or one of them, or It is good also as what registers the contact information etc. which replaces. For example, instead of an e-mail, a form in which a message such as a moving picture form is broadcast to the base station 2 using multicast or the like may be employed. Further, it is possible to adopt a form in which wireless communication terminal users make a voice call with each other using PoC (Push-to-talk over Cellular). In this case, the information exchange server 4 functions as a PoC server that manages a PoC group and realizes a voice call between users.

  In the above-described embodiment, the wireless communication terminals located in the vicinity have been described as being grouped regardless of the intention of the user. However, the request that the user does not want to receive a message or cannot cooperate or provide information. The wireless communication terminal of the user who has the above may be excluded from the grouping target. For example, a user who has obtained consent in advance for message distribution is registered in the storage unit 44 of the information exchange server 4, and the wireless communication of the user who has obtained consent from the wireless communication terminal that has replied from the base station 2. You may make it extract a terminal and deliver a message. In addition, for example, a method of withdrawing from a group may be described in a message to be transmitted first, and a user who does not want to receive a message may be excluded from a message transmission target (that is, a group) from the next time.
