Then, the current position is acquired again, and if it is further than the predetermined distance from the previously acquired position (YES in S111), the process proceeds to step S106. If the distance is within the predetermined distance (NO in S111), the process proceeds to step S108.

  The server device 2 that has received the request for bidirectional communication (YES in S206) authenticates the portable terminal 1 that has requested bidirectional communication (S208), and transmits a success notification to the portable terminal 1 when the authentication is successful (S208). ). The data structure of the success notification is shown in FIG. As shown in FIG. 9F, the success notification includes data indicating that the authentication is successful.

  The portable terminal 1 receives from the server device 2 that the two-way communication has been successfully authenticated (S113), and a bidirectional communication connection is established between the portable terminal 1 and the server device 2 (S114, S209).

  When the two-way communication connection is established between the portable terminal 1 and the server apparatus 2, the portable terminal 1 enters data reception / display processing (S115), and the server apparatus 2 enters data push processing (S210). Details of the data reception / display processing and data push processing will be described later.

  In the data push process, when the delivery of all transmission messages is completed (YES in S211), the server device 2 transmits an instruction to disconnect the bidirectional communication connection to the mobile terminal 1.

  Further, the mobile terminal 1 performs data reception / display processing and periodically acquires the current position (S116). If the disconnection condition is met (YES in S117), the two-way communication with the server device 2 is disconnected (S120), and the process proceeds to step S108.

Here, the cutting conditions are as follows.
(A) The current position and the current time are not included in the position information list.
(B) Elapse of the connection continuation time designated by the server device 2.
(C) A disconnection instruction is received from the server device 2.

  If the power does not match the disconnection condition (NO in S117), the power button operation of the portable terminal 1 is turned off by the power button operation (YES in S118), the bidirectional communication is disconnected (S119), The process ends.

  Next, the flow of data reception / display processing in the mobile terminal 1 and data push processing in the server device 2 will be described with reference to FIG.

  The portable terminal 1 acquires the current position (S151) and transmits it to the server device 2 (S152). The data structure of the current position data to be transmitted is shown in FIG. As shown in FIG. 10A, the current position data includes information (latitude, longitude) indicating the current position and identification information of the data type of bidirectional communication.

  The server device 2 that has acquired the current position (YES in S251) stores the acquired current position (S232), and there is a message to be transmitted from the current position and the transmission message list included in the transmission message list DB 66. Whether or not (S253). Whether or not there is a message to be transmitted is determined based on whether or not the current position is included in the region specified by the “position range” and the target transmission message has not been transmitted to the same user in the past.

  If there is a transmission message to be notified (YES in S254), the mobile terminal 1 is notified of the transmission message (S255). FIG. 10B shows a data structure of data for notifying a transmission message. As shown in (8-2) and (8-3) of FIG. 10 (b), the data notifying the transmission message includes either the message data body or data indicating the URL where the message can be confirmed. Yes. This may be properly used depending on the data amount of the message to be transmitted. Further, connection maintenance request data shown in (8-1) of FIG. 10B is transmitted from the server device 2 to the mobile terminal 1. The connection maintenance request data is transmitted after a certain time (for example, 10 minutes) from the time when the position information list is transmitted.

  As shown in FIG. 11B, the position information list managed by the server device 2 includes “reference position management ID”, “reference position name”, “bidirectional communication destination”, “connection time”, “Reference position range 1”, “reference position range 2”, “location management ID”, “name”, “position range 1”, “position range 2”, and “message ID” are included.

“Location management ID” is an ID for managing information for push-type delivery of a transmission message. “Position range 1” and “Position range 2” indicate areas where push messages are distributed. The area is set in the same manner as the “reference position range”. “Message ID” specifies a transmission message to be distributed by push type.
A plurality of portions from “location management ID” to “message ID” can be set. By setting a plurality, it is possible to transmit a transmission message in different regions (for example, the first region and the second region).

  The mobile terminal 1 that has received the connection maintenance request (YES in S153) stores the connection end time of bidirectional communication (S154).

  Furthermore, when the portable terminal 1 receives the transmission message from the server device 2 (YES in S155), the portable terminal 1 displays the received transmission message on the display unit 13 (S156). Note that the transmission message is not limited to display, and may be notification by voice or vibration.

  If the received transmission message has a format that refers to a URL (YES in S157), the mobile terminal 1 requests the transmission message body (data entity) from the server device 2 in accordance with the user's instruction (S158). Upon receiving the request for the transmission message body (YES in S256), the server apparatus 2 transmits the transmission message body to the mobile terminal 1 (S257). And the portable terminal 1 which received the transmission message main body (S159) displays a transmission message main body (S160).

  A display example in which a transmission message is displayed is shown in FIGS. FIG. 5 shows an example in which a transmission message is displayed in two stages, and a display example when entering the first area is shown in FIG. 5 (c), and the second area narrower than the first area is entered. A display example at this time is shown in FIG. Here, when the first area is in a range where the store (home center Tomeli) can be seen, and the second region is in the vicinity of the store entrance, and the user comes to the range where the user can see the store, the store coupon (FIG. 5 ( c)) is distributed, and bargain information (FIG. 5 (d)) is distributed when entering the store entrance.

  In the above embodiment, the area for transmitting the transmission message is set according to the position information. However, the position information is set not at the area but at the point, and the distance to the point is acquired by the position acquisition unit 17. May be set as a region where a transmission message is transmitted.

  As described above, in the present embodiment, when the mobile terminal 1 enters the reference position range indicated in the position information list, the two-way communication connection with the server device 2 is established. When the mobile terminal 1 enters the position range indicated in the position information list, the transmission message is distributed from the server device 2 by push distribution. Further, when a plurality of position ranges are set, the transmission message is distributed by push type distribution in different ranges. Further, when the disconnection condition is satisfied, such as when the mobile terminal 1 is out of the reference position range, the bidirectional communication connection between the mobile terminal 1 and the server device 2 is disconnected.

  Therefore, according to this Embodiment, the power consumption of the portable terminal 1 can be suppressed while distributing information from the server device 2 to the portable terminal 1 by push-type distribution.
