[Overview]
FIG. 1 is a diagram for explaining an information processing system S according to an embodiment. The information processing system S includes one or more movable communication terminals 1 and a server 2. The communication terminal 1 and the server 2 transmit / receive data to / from each other via the base station. The base station to which the communication terminal 1 is connected is, for example, a mobile base station 3 constituting a mobile phone network.

  For example, measurement information relating to a plurality of areas is recorded in the server 2. The server 2 refers to the previous update time of the measurement information and identifies an area where the measurement information needs to be updated. The server 2 selects the communication terminal 1 that can acquire the measurement information of the area whose information is to be updated, and requests to acquire the measurement information around the communication terminal 1. Since the communication terminal 1 transmits information indicating the position of its own terminal to the server 2, the server 2 can select the communication terminal 1 that can acquire measurement information that needs to be updated.

  The measurement information acquired by the communication terminal 1 includes large-capacity information such as image data. For this reason, when a plurality of communication terminals 1 attempt to transmit the acquired measurement information to the server 2 via a specific mobile base station 3 at once, the load on the mobile base station 3 increases, and data is stored in the mobile base station 3. There is a possibility of failure in sending and receiving.

  Therefore, the server 2 acquires information indicating the network load serving as a data communication path between the communication terminal 1 and the server 2 and loads the network to which the communication terminal 1 that requested acquisition of measurement information is connected. Is smaller than a predetermined load that is a guideline for allowing transmission of measurement information, the communication terminal 1 is requested to transmit measurement information via the mobile base station 3 to which the communication terminal 1 is connected. In this way, the information processing system S can collect data from the communication terminal 1 without imposing an excessive burden on the network including the mobile base station 3.

In addition, the control unit 17 functions as a measurement information acquisition unit 171, a terminal information transmission unit 172, and a measurement information transmission unit 173 by executing the program recorded in the recording unit 15.

  For example, the measurement information acquisition unit 171 acquires measurement information such as a captured image, distance measurement data, point cloud data, and ambient temperature. The terminal information transmission unit 172 transmits the location information of the own terminal to the server 2 via the communication unit 16. Further, the measurement information transmission unit 173 transmits the measurement information to the server 2. The measurement information transmission unit 173 transmits acquisition information indicating that measurement information has been acquired to the server 2 when acquiring measurement information.

[Configuration of Server 2]
FIG. 3 is a diagram schematically showing the configuration of the server 2. The server 2 includes a recording unit 21, a control unit 22, and a communication unit 23.

  The recording unit 21 includes, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), and an HDD (Hard Disk Drive). In the ROM, for example, a program executed by the control unit 22 is recorded. In the RAM, for example, the communication terminal 1 selected for requesting the measurement information and the area where the measurement information needs to be updated are recorded.

  In the HDD, for example, network information that is information indicating a load on a network that is a data communication path between the communication terminal 1 and the server 2, identification information of the communication terminal 1, position information of the communication terminal 1, and the communication terminal 1 Communication terminal information including information related to the connected base station, measurement information regarding a plurality of areas, and update information indicating the update date and time of the measurement information are recorded.

  The control unit 22 executes the program recorded in the recording unit 21 to thereby execute the terminal information acquisition unit 201, the area specifying unit 202, the information acquisition request unit 203, the acquired information reception unit 204, the network information acquisition unit 205, and the information It functions as the transmission request unit 206.

  The terminal information acquisition unit 201 acquires information indicating the position of one or more movable communication terminals 1 and information on a base station to which the communication terminal 1 is connected. The terminal information acquisition unit 201 may further acquire a past data communication amount from a predetermined period of the communication terminal 1. The predetermined period is a period that serves as a standard for measuring the amount of data communication when a communication charge is imposed, and is, for example, one month. The terminal information acquisition unit 201 records each acquired information in the communication terminal information table in the recording unit 21.

  FIG. 4 is a table showing an example of the communication terminal information table. The example of the communication terminal information table shown in FIG. 3 includes a terminal identifier that is an ID for identifying the communication terminal 1, a position identifier that indicates a position where the communication terminal 1 exists, and a base station to which the communication terminal 1 is connected. And the date and time when the data communication volume and the communication terminal information were updated more than the predetermined period of the communication terminal 1 are described. The position identifier is an ID that identifies one of a plurality of areas divided in the map, for example.

  In the example shown in FIG. 4, the mobile base station 3 and the Wi-Fi base station are described as the types of base stations to which the communication terminal 1 is connected. The Wi-Fi base station has a smaller communication range than the mobile base station 3, but a large communication capacity. When the type of the base station to which the communication terminal 1 is connected is the mobile base station 3, the server 2 communicates with the communication terminal 1 when a predetermined condition indicating that the communication load of the mobile base station 3 is light is satisfied. Asks to send the measurement information obtained.

  The area specifying unit 202 specifies an area in which measurement information is acquired by requesting the communication terminal 1 from among a plurality of areas. Specifically, the area specifying unit 202 specifies the area based on whether or not a predetermined period for updating the measurement information has elapsed. The predetermined period can be arbitrarily changed according to the data to be acquired. For example, if the data to be acquired is image data, the measurement information is updated at monthly intervals, and if the data is temperature data, the measurement information is updated every day. Moreover, the said area | region is matched with the position identifier mentioned above, for example.

  FIG. 5 is a table showing an example of the update information table. In the update information table, the location identifier of the region, the area identifier indicating the radio wave arrival area of the mobile base station 3, the information indicating whether or not the communication terminal 1 has been requested to acquire the measurement information, and the fact that the measurement information has been acquired The information shown and the update date and time of measurement information in a plurality of areas are recorded.

  For example, the area specifying unit 202 refers to the update date / time of the measurement information for each position identifier representing each area, and has already requested the communication terminal 1 to acquire the measurement information when the measurement information needs to be acquired. Confirm whether or not. When the communication terminal 1 is not requested to acquire measurement information, the area specifying unit 202 specifies the area as an area where measurement information needs to be acquired.

  In the example shown in FIG. 5, the area represented by the position identifier of ID1 has already requested the communication terminal 1 whose terminal identifier is specified by KL2020 to acquire measurement information. On the other hand, the area represented by the position identifier of ID2 does not request the communication terminal 1 to acquire measurement information. Therefore, when the update date and time “September 12, 2016, 12:00” is in the past that is older than the predetermined period, the area specifying unit 202 acquires the measurement information in the area represented by the position identifier of ID2. Identify as necessary area.

  The information acquisition request unit 203 requests the communication terminal 1 determined based on the information indicating the position of the communication terminal 1 to acquire measurement information of the area specified by the area specifying unit 202. Specifically, the information acquisition request unit 203 specifies a communication terminal 1 that can acquire measurement information in the area specified by the area specifying unit 202 with reference to the communication terminal information table, and requests the communication terminal 1. The communication terminal 1 that requests acquisition of measurement information records, for example, the communication terminal 1 in which the same position identifier as the position identifier of the area from which the communication terminal 1 acquires measurement information is recorded, or the position identifier of the area adjacent to the area. Communication terminal 1.

  The information acquisition request unit 203 records in the recording unit 21 information identifying the communication terminal 1 that has been requested to acquire measurement information, and acquires measurement information for the communication terminal 1 that has already been requested to acquire measurement information. You may not make a request to do. In other words, instead of confirming whether the area specifying unit 202 has already requested the communication terminal 1 to acquire measurement information, the information acquisition request unit 203 has already requested the communication terminal 1 to acquire measurement information. The information acquisition request unit 203 may not make a request to the communication terminal 1 that has already requested acquisition of measurement information.

  FIG. 6 is a flowchart of processing in which the server 2 requests the communication terminal 1 to acquire measurement information. First, the area specifying unit 202 starts from a process of specifying an area for acquiring measurement information with reference to the update information table (S61).

You may request to send measurement information.

  In addition to the above conditions, the information transmission requesting unit 206 further sends measurement information to the communication terminal 1 via the mobile base station 3 when the data usage amount of the communication terminal 1 from the past for a predetermined period is smaller than a predetermined value. May be requested to send. For example, the information transmission request unit 206 acquires the contract information of the communication terminal 1 and transmits the measurement information when the data usage amount of the communication terminal 1 is less than 90% of the upper limit of the data usage amount where the communication fee is fixed. Request. In this way, the data transmission amount of the communication terminal 1 per unit period can be suppressed within the target range.
