Description

  The present invention relates to an area map creation system, an area map creation method, an area map creation device, a program, and a recording medium.

  In a mobile phone system, radio waves of mobile radio base stations in adjacent service areas are also obtained at each location in each service area so that the mobile phone terminal can make a call at a sufficient reception level at each location in each service area. In addition, it is necessary to investigate what electric field intensity from which mobile radio base station can be received, but the electric field intensity of radio waves is measured by using an electric field intensity measuring device and a GPS (Global Positioning System) receiver. Conduct a running test with the vehicle installed, receive radio waves at each point in the service area, measure the electric field strength of the radio waves at that point, and measure the electric field strength along with the position information of that point obtained by the GPS receiver Is recorded on a recording medium.

  Various techniques related to such a background are known (see, for example, Patent Document 1).

  For example, Patent Document 1 discloses an exchange system, a plurality of mobile radio base stations that are connected to the exchange system and each form a mobile communication service area, and the mobile communication service area. A mobile communication service area reception level information collecting method including at least one mobile phone terminal connected to a mobile radio base station forming the network is described. More specifically, the mobile phone terminal measures the reception level of the reception frequency from the mobile radio base station during a call, and incorporates the calculation of the current position when measuring the reception level of the reception frequency. The reception level information including the reception level data of the reception frequency obtained by measuring the reception level of the reception frequency and the position data obtained by calculating the current position is transmitted to the mobile radio base station during a call. It is inserted into the transmission line control signal and transmitted to the mobile radio base station. Then, the switching system reads the reception level information inserted into the line control signal transmitted via the mobile radio base station, stores it in the database, and has passed a predetermined period as a collection period of the reception level information Based on the reception level information read from the database, mapping is performed to display on the map information indicating the reception level of the reception frequency from each mobile radio base station at the reception level measurement point of the reception frequency on the map. The map data generated by mapping the reception level of the reception frequency is stored in the database. In this way, depending on the reception level information collection method for this mobile communication service area, it is necessary to grasp the status of the reception level of radio waves in the service area after changing the frequency of the mobile radio base station or changing the transmission power frequency. It is not necessary to carry out a lot of man-hours such as measuring the electric field strength of radio waves in a service area by a running test using a vehicle equipped with a radio field strength measuring device. The measurement data of the reception level of the telephone terminal can be easily measured and collected, and the man-hours for grasping the status of the reception level of the radio wave in the service area can be reduced.

  In addition, it is not clear whether or not a call is actually possible.

  Various techniques relating to such a background are known (see, for example, Patent Document 2).

  For example, Patent Document 2 describes a navigation system having a map display means, a position detection means, and a mobile communication means. More specifically, this navigation system stores the history of communication availability information obtained from mobile communication means in association with current position information detected by the position detection means. And this navigation system superimposes and displays the communication availability information on the map displayed on the map display means. In this way, depending on the navigation system, it is possible to indicate on the map for navigation where the communication network can actually be used by using the own terminal. Information can be shown to the user, and convenience for the user to secure the communication path is improved.

  In addition, a communication provider of a wireless communication system needs to collect communication quality information from wireless terminals distributed in a wide area in order to grasp the communication quality state in the service area.

  Various techniques related to such a background are known (see, for example, Patent Document 3).

  For example, in Patent Document 3, for each area, a database server having an area map creating means for creating an area map in which communication quality information is mapped at each position, a plurality of cellular base stations for mobile communication, and a plurality of high-speed wireless communications An area map construction system having an access point for communication, a mobile communication interface communicating with a cellular base station, a high-speed wireless communication interface communicating with the access point, and a plurality of wireless terminals having positioning means for positioning current position information is described ing. More specifically, the database server determines measurement area range information that identifies an area where the number of communication quality information is equal to or less than a predetermined threshold value, and measurement quality range information that represents a measurement range of communication quality. In this case, the measurement quality range information is set for the mobile communication interface of the wireless terminal so that the communication quality is within the range of the low communication quality that represents the communication boundary with the cellular base station. For the interface, one having a range of communication quality higher than the level indicating communication with the access point is set. On the other hand, the wireless terminal stores communication quality information from the base station and the access point measured by the mobile communication interface and the high-speed wireless communication interface, respectively. Then, the database server transmits a measurement request including measurement area range information and measurement quality range information to the wireless terminal. Then, the wireless terminal receives the measurement request. The wireless terminal includes communication area information based on the position of the wireless terminal itself in the measurement area range information included in the measurement request, and in the measurement quality range information for each communication interface included in the measurement request, It is determined whether communication quality information of the communication interface of the wireless terminal is included. If the determination is true, the wireless terminal returns a measurement response including the current position information and communication quality information to the database server. Then, the database server receives a measurement response including the current position information and communication quality information from the wireless terminal. In this way, depending on this area map construction system, the database server specifies measurement area range information with a small amount of information in order to create an area map based on communication quality information, and communicates only from wireless terminals within that range. Since the quality information can be received, the number of times of transmission of the communication quality information in a general wireless terminal is reduced as much as possible, and the entire network including the wireless section is not loaded.

  In addition, with the increase in climbers, rescue requests are being made by mobile phones.

  Various techniques related to such a background are known (see, for example, Patent Document 4).

  For example, Patent Document 4 describes a mobile phone service area information providing method for providing service area information indicating a service area of a mobile phone service. More specifically, in this mobile phone service area information providing method, the mobile phone specifies the radio wave reception status of the mobile phone. In this mobile phone service area information providing method, the mobile phone transmits location information of the mobile phone and information indicating the reception status of the radio wave to a server device that stores the service area information. And this mobile telephone service area information provision method performs control which a mobile telephone updates the display of the service area information received from the server apparatus at any time based on the positional information and the information which shows the reception condition of an electromagnetic wave. In this mobile phone service area information providing method, the server device updates the service area information to be stored based on the position information received from the mobile phone and the information indicating the reception status of radio waves. In this way, the latest service area information can be collected on the basis of the route on which the climber actually walks depending on the method for providing mobile phone service area information.

  In recent years, mobile devices such as mobile phones have rapidly spread.

  Various techniques related to such a background are known (see, for example, Patent Document 5).

  For example, Patent Document 5 describes a method for collecting position information in a mobile device. More specifically, this location information collection method obtains at least once the three-dimensional location information of a mobile device in geography. In the first area where wireless communication with the base station cannot be performed, the position information is collected in the first area where wireless communication with the base station cannot be performed. Complement and memorize based on atmospheric pressure. Then, this location information collection method transmits the stored location information to the base station in the second area where wireless communication can be performed. In this way, depending on the location information collection method, the information outside the service area can be collected more reliably.

  The control unit 131 is a device that controls other devices inside the mobile phone 130. The control unit 131 stores the received signal power information obtained from the communication unit 133, the position information obtained by the position information acquisition unit 132, and time information in association with each other in the storage device 136. The control unit 131 connects to the public network 150 from the communication unit 133 at a predetermined timing. Then, the control unit 131 transmits the data stored in the storage device 136 to the server 110 via the base station 151, the communication control station 152, and the common line signal network 153.

  The position information acquisition unit 132 acquires position information of the current position. For example, the position information acquisition unit 132 acquires position information of the current position using GPS or the like.

  The communication unit 133 communicates with the public network 150. The communication unit 133 divides the received signal power of the radio wave transmitted from the base station 151 of the mobile phone network 50 into five levels of out-of-range, weak, small, medium, and strong, and five levels of 0, 1, 2, 3, and 4. It expresses.

  The display unit 134 displays the device operation result.

  The server 110 includes a database 111 that stores data sent from the mobile phone 130, a control unit 112 that performs various controls within the server, and a storage unit 113 that stores information necessary for the operation of the control unit 112. The control unit 112 may be an example of a “communication device selection unit” and an “area map creation unit” in the present invention.

  The control unit 112 of the server 110 accumulates the received signal power, communication state information, position information, and time information sent from the mobile phone 130 in the database 111.

  The reception signal power collection and transmission processing performed by the control unit 131 of the mobile phone 130 will be described with reference to the flowchart of FIG. In step 1 (S1), reception signal power and communication state information are acquired from the communication unit 133. The communication unit 133 divides the received signal power of the radio wave transmitted from the base station 151 of the public network 150 into five levels of out-of-range, weak, small, medium, and strong, and this is divided into five levels of 0, 1, 2, 3, and 4. Expressed in stages. In addition, the communication unit 133 acquires information on the communication state (standby, communicating) of the mobile phone 130. In S <b> 2, position information and time are acquired from the position information acquisition unit 132. In step S3, the received signal power, communication state, position information, and time information acquired in steps S1 and S2 are stored in the storage device 136 in association with each other. Data stored in the storage device 136 at S3 is given data numbers in the order of storage, and stores data acquisition time, location information, received signal power, and terminal status information. An example of data stored in the external memory is shown in FIG. In S4, it is determined whether the amount of data stored in the external memory exceeds the specified value.
