There is a technique for mounting a GPS (Global Positioning System) on a mobile information communication terminal such as a mobile phone and measuring the position of the mobile information communication terminal.
In the wireless communication service, it is necessary for the mobile information communication terminal and the base station to communicate. The base station defines a communicable area for each base station. Depending on the distance to the mobile information communication terminal, the positional relationship (there is a shield such as a building), the mobile information It is determined whether or not the communication terminal can communicate. Electric field strength is used to determine whether communication is possible. For example, three antenna icons are displayed on a mobile phone display, and the number of antenna icons to be displayed is determined according to the electric field strength.

  A portable information communication terminal 100 according to the present embodiment is portable and performs wireless communication. As shown in FIG. 1, an electric field strength detection module 110, a GPS 120, an electric field strength / area correspondence information storage module. 130, a control module 140, a control information receiving module 150, a correspondence information transmitting module 160, and a communication module 170.

The electric field strength detection module 110 is connected to the control module 140 and detects the electric field strength when the mobile information communication terminal 100 performs wireless communication with the base station. When the detected electric field strength is larger than a predetermined strength (threshold), wireless communication is possible, and when the electric field strength is equal to or lower than the predetermined strength, it means that wireless communication is not possible. The detected electric field strength value is passed to the control module 140. Further, the detected time may be passed to the control module 140 in correspondence with the value of the electric field strength.
The GPS 120 is connected to the control module 140, measures the position of the GPS 120 (the GPS 120 is built in the portable information communication terminal 100, and therefore the position of the portable information communication terminal 100), and the measurement result is sent to the control module 140. hand over. Further, the measured time may be transferred to the control module 140 in correspondence with the position. The GPS 120 is controlled by the control module 140 such as activation. For example, the GPS 120 is controlled by the control module 140 for power on / off and position measurement.

The electric field strength / area correspondence information storage module 130 is accessed from the control module 140. The position measured by the GPS 120 activated by the control module 140 is stored. Further, the electric field intensity detected by the electric field intensity detection module 110 and the position thereof may be stored in correspondence. Further, the time at which the position or the electric field intensity is measured may be stored in correspondence.
For example, data such as a field intensity area correspondence table 600 shown in the example of FIG. 6 is stored. FIG. 6 is an explanatory diagram showing an example of the data structure of the electric field intensity area correspondence table 600. The electric field intensity area correspondence table 600 is No. A column 610, a time column 620, a position data column 630, and an electric field strength column 640 are provided. That is, the position data at which the portable information communication terminal 100 cannot communicate, the electric field strength at that time, and the time measured are stored in association with each other.
No. The column 610 stores a code for uniquely identifying the correspondence between the position data measured in the portable information communication terminal 100 and the electric field strength.
The time column 620 stores the time when the electric field strength detection module 110 detects the electric field strength or the time when the GPS 120 measures the position.
The position data column 630 stores position data measured by the GPS 120. This position is a position at which the portable information communication terminal 100 has become unable to communicate.
The field strength field 640 stores the field strength value detected by the field strength detection module 110. The value of the electric field strength is not more than a predetermined strength, and is an electric field strength at which communication is impossible.

When the electric field intensity detected by the electric field intensity detection module 110 is equal to or lower than a predetermined intensity, control is performed so that the GPS 120 is activated. That is, when the portable information communication terminal 100 becomes unable to communicate, the position is measured, and the position data is data for generating an area map of a dead area (a communication impossible area). Then, the position measured by the GPS 120 is stored in the electric field strength / area correspondence information storage module 130. In addition, the electric field intensity detected by the electric field intensity detection module 110 may be stored in the electric field intensity / area correspondence information storage module 130 in correspondence with the position. Then, the correspondence information transmission module 160 is controlled to transmit the contents stored in the electric field strength / area correspondence information storage module 130 to the electric field strength map generation device 200.

The control module 140 may control the GPS 120 to be activated after a predetermined time from when the electric field strength becomes equal to or lower than the predetermined strength. This predetermined time is referred to as control information, and more specifically, referred to as a time parameter. The reason why such control information is provided is that when communication is impossible and communication may be frequently reversed, the power consumption increases when the GPS 120 is turned on / off each time. The GPS 120 is activated after a predetermined time from the situation where communication is impossible, and the position is measured to suppress power consumption.
Further, the control information may be changed according to the information stored in the electric field strength / area correspondence information storage module 130. For example, when the position measured by the GPS 120 is a position that has already been measured (that is, a position stored in the electric field strength / area correspondence information storage module 130), the control information is used to measure the dead area in detail. May be set shorter.
Further, the control information may be changed according to the information related to the control information transmitted from the electric field strength map generating apparatus 200 via the communication module 170 and the control information receiving module 150. For example, the control information transmitted from the electric field strength map generation device 200 may be set.

  The control information receiving module 150 is connected to the control module 140 and the communication module 170. Information relating to the control information transmitted from the electric field strength map generating apparatus 200 is received via the communication module 170 and passed to the control module 140.

When the wireless communication is enabled by the control module 140, the information stored in the electric field strength / area correspondence information storage module 130 is transmitted to the electric field strength map generation device 200 via the communication module 170. To do. The information to be transmitted includes, for example, a field strength area correspondence table 600 stored in the field strength / area correspondence information storage module 130.
Note that “when wireless communication is enabled” means that wireless communication is possible immediately after wireless communication is enabled, after a predetermined time has elapsed, or wireless communication is possible. This is a case where communication is possible, such as when a predetermined time is reached, and any case where wireless communication is possible. In addition, the case where the predetermined time is reached means a predetermined periodic time, for example, when it is 1:00 am, 0 minutes per hour, etc., and particularly when the communication load is low (1:00 am 2 o'clock etc.) may be set.

  The communication module 170 is connected to the control information receiving module 150 and the correspondence information transmitting module 160, and performs information communication with the electric field strength map generating apparatus 200. The control information received from the electric field strength map generating device 200 is passed to the control information receiving module 150, and the information passed from the correspondence information transmitting module 160 is transmitted to the electric field strength map generating device 200.

Information received from the portable information communication terminal 100 (including at least position data) is passed to the correspondence information receiving module 220, and the control information passed from the control information transmission module 230 is transmitted to the portable information communication terminal 100.

The correspondence information receiving module 220 is connected to the communication module 210 and the electric field strength map generation module 240, and receives a position where the electric field strength is equal to or lower than a predetermined strength from the portable information communication terminal 100 via the communication module 210.
The control information transmission module 230 is connected to the communication module 210 and the control information generation module 250, and transmits the control information generated by the control information generation module 250 to the portable information communication terminal 100 via the communication module 210.

  The electric field strength map generation module 240 is connected to the correspondence information receiving module 220 and the map DB 260, and generates an area map related to the distribution of electric field strength based on the position received by the correspondence information receiving module 220. For example, the position data transmitted from a plurality of portable information communication terminals 100 is mapped (plotted) on a map to generate an area map of a dead area. The generated area map is stored in the map DB 260. The electric field strength map generation module 240 may output the area map to an output device such as a display, print it with a printing device such as a printer, or send it to another system or the like.

Note that the position data to be transmitted in advance is read into the memory from the field strength area correspondence table 600 in the field strength / area correspondence information storage module 130 via the control module 140.
In step S704, the correspondence information transmission module 160 determines whether or not all position data to be transmitted has been read. If all the data are read in this determination (Y), the process proceeds to step S714. Otherwise (N), the process proceeds to step S706.

In step S706, the correspondence information transmission module 160 reads the position data read in step S702 and the position data already transmitted (stored in the electric field strength / area correspondence information storage module 130 and read this via the control module 140). Matching process is performed. “Matched” includes a case where the two match each other and a case where there is a difference between the two but the difference is equal to or less than a predetermined value (the same applies hereinafter).
In step S708, if the correspondence information transmission module 160 matches as a result of the matching process in step S706 (Y, that is, if it matches with already transmitted position data), the process proceeds to step S712, otherwise (N). Advances to step S710.

In step S710, the correspondence information transmission module 160 sets the position data read in step S702 as transmission data.
In step S712, the correspondence information transmission module 160 deletes the position data read in step S702. That is, the amount of communication is reduced without overlapping the previously transmitted position data. After the processes of step S710 and step S712, the process returns to step S702 and the process is repeated.
In step S <b> 714, the communication module 170 transmits the position data set as the transmission data in step S <b> 710 to the electric field strength map generation device 200 in accordance with the instruction of the correspondence information transmission module 160.

FIG. 8 is a flowchart illustrating an example of a time parameter setting process. That is, it mainly shows an example of processing by the control information receiving module 150, and sets the time parameter set in step S504 of the flowchart shown in the example of FIG.
In step S <b> 802, the control information receiving module 150 acquires the position data measured by the GPS 120 via the control module 140 and the position data in the electric field strength / area correspondence information storage module 130, and performs matching between them. However, it may be a value different from the “predetermined value” in the case where it is determined whether or not the difference is a predetermined value in the matching process in step S706 of FIG. For example, the predetermined value in the matching process in step S802 may be a value that is larger than the predetermined value in the matching process in step S706. That is, it is determined whether or not they match when setting the time parameter, and is basically different from the processing example of FIG. 7 in which the same position data is not transmitted.

In step S804, if the control information receiving module 150 matches as a result of the matching process in step S802 (Y, that is, if it matches with the already measured position data), the process proceeds to step S806, otherwise (N). Advances to step S808.
In step S806, the control information receiving module 150 sets the time parameter to be shorter than the current one. In other words, after detecting that the vehicle is in the dead area, the time until the GPS 120 is activated is shortened, and the position data is measured in more detail.

In step S808, the control information receiving module 150 determines whether or not the difference between the two in step S802 is within a predetermined range. If the determination is within the predetermined range (Y), the process proceeds to step S810. Otherwise (N), the process proceeds to step S812.
In step S810, the control information receiving module 150 sets the time parameter to be longer than the current one. Since the position is close to the position already measured, the time parameter is lengthened in order to perform measurement at a further distance.
In step S812, the control information receiving module 150 sets the time parameter to a default value. Since it is at a position different from the position that has already been measured, measurement is performed using a time parameter that is assumed in advance.
Note that the processing values in steps S806, S810, and S812 may be changed according to the purpose.

  FIG. 9 is a flowchart illustrating an example of time parameter setting processing in the portable information communication terminal 100. That is, it mainly shows an example of processing by the control information receiving module 150, and sets the time parameter set in step S504 of the flowchart shown in the example of FIG. Here, the time parameter set by the electric field strength map generating apparatus 200 is adopted.

In step S902, the control information receiving module 150 receives the time parameter for each area via the communication module 170.
In step S904, the control information receiving module 150 sets parameters for each area according to the time parameter received in step S902. For example, when the control module 140 waits for a time interval according to the time parameter before the process of step S514 in the flowchart of the example of FIG. 5, the time parameter varies depending on the position measured by the GPS 120. Become. This is used when the field strength map generation apparatus 200 wants to control the measurement interval for each area.

FIG. 10 is a flowchart illustrating an example of a time parameter setting process in the electric field strength map generation apparatus 200. That is, it mainly shows an example of processing by the control information generation module 250, and sets time parameters according to the population density.
In step S1002, the control information generation module 250 selects an area. That is, the area where the time parameter is to be changed is selected.
In step S1004, the control information generation module 250 determines whether the population density in the area is higher than a predetermined value. If the determination is high (Y), the process proceeds to step S1006. Otherwise (N), the process proceeds to step S1008.

In step S1006, the control information generation module 250 sets the time parameter in the area selected in step S1002 to be shorter than the default value. That is, since the population density is high, there is a high demand to be a sensitive area if it is a blind area, so the position data of the dead area is collected in detail.
In step S1008, the control information generation module 250 sets the time parameter in the area selected in step S1002 to be longer than the default value.
In step S1010, the control information transmission module 230 transmits the time parameter set in step S1006 or step S1008 to the portable information communication terminal 100 via the communication module 210. Thereafter, the portable information communication terminal 100 performs processing according to the flowchart shown in FIG.
