The outlier detection unit 422 first determines whether or not the GPS accuracy is greater than a predetermined value for each piece of log information including GPS information. When the GPS accuracy is larger than a predetermined value, log information including information related to the GPS accuracy is detected as an outlier.

  According to this embodiment, information whose position information accuracy is worse than a predetermined value can be excluded. As a result, the accuracy of the statistical information generated by the statistical information generation unit 424 can be improved. Further, according to the present embodiment, log information can be separated into log information outdoors or near windows and log information indoors. As a result, the statistical information generation unit 424 can generate statistical information regarding each case.

  The GPS accuracy is expressed using, for example, CEP (Circular Error Probability). CEP is expressed as the radius of a circle when the probability that the GPS receiver is in a particular circle is 50%. Even when the GPS receiver is outdoors or indoors, the CEP is small when the GPS signal is easily received (for example, near a window). On the other hand, when the GPS receiver is in a place where it is difficult to receive GPS signals such as indoors, the CEP becomes a large value.

  Places where GPS signals are easily received tend to easily receive radio communications or mobile communication radio waves, and places where GPS signals are difficult to receive tend to be difficult to receive radio communications or mobile communications radio waves. Therefore, when the GPS accuracy is larger than a predetermined value, by detecting log information including information on the GPS accuracy as an outlier, communication environment information in a place where it is difficult to receive radio waves such as indoors, It can be detected as an outlier. As a result, the statistical information generation unit 424 can generate statistical information mainly using communication environment information in places where it is easy to receive radio waves such as outdoors or near windows. The information collection server 120 can provide information indicating the effect when the base station is installed outdoors, for example, based on the generated statistical information.

  The outlier detection unit 422 may detect log information including information related to the GPS accuracy as an outlier when the GPS accuracy is smaller than a predetermined value. In this case, the statistical information generation unit 424 can generate statistical information mainly using communication environment information in places where it is difficult to receive radio waves such as indoors. The information collection server 120 can provide information indicating the effect when a base station is installed indoors, for example, based on the generated statistical information.

  According to another embodiment, the position information, the communication environment information of the communication terminal, the information related to the time when the communication environment information of the communication terminal is acquired, and the one or more communication for at least a part of the one or more log information When terminal identification information for identifying each of the terminals 110 is associated, the outlier detection unit 422 detects specific log information as an outlier by the following procedure. The outlier detection unit 422 first classifies the log information received from the log information acquisition unit 414 for each communication terminal 110 identified by the terminal identification information, based on the terminal identification information. Next, the outlier detection unit 422 determines the moving speed of the communication terminal 110 for each piece of log information classified for each terminal identification information. Thereafter, the outlier detection unit 422 detects an outlier based on the moving speed of the communication terminal.

  According to this embodiment, even if the position information included in the log information indicates a position that is significantly different from the position where the communication environment information is actually acquired due to some error, such information is excluded. Can do. As a result, the accuracy of the statistical information generated by the statistical information generation unit 424 can be improved. Further, according to the present embodiment, log information can be separated for each means of transportation of the user of the communication terminal 110 (eg, walking, bicycle, automobile, railway, high-speed railway, etc. can be exemplified). As a result, the statistical information generation unit 424 can generate statistical information regarding each case.

The outlier detection unit 422 determines the moving speed of the communication terminal 110 by the following procedure, for example. Since each piece of log information classified for each terminal identification information includes information related to the acquisition time of the communication environment information, the outlier detection unit 422 can determine the moving speed of the communication terminal 110. The log information stored in the data table 300 will be described as an example. The outlier detection unit 422 performs communication at the position indicated by the log information stored in the second row of the data table 300 by, for example, the following equation (1). The moving speed v of the terminal 110 is determined.
v = dL / dt (1)
Here, dL represents the distance between the position indicated by the log information stored in the second row of the data table 300 and the position indicated by the log information stored in the first row of the data table 300. dt represents the difference between the time indicated by the log information stored in the second row of the data table 300 and the time indicated by the log information stored in the first row of the data table 300.

  The outlier detection unit 422 can determine the moving speed of the communication terminal 110 in the same manner for other log information stored in the data table 300. The outlier detection unit 422 may add information indicating the moving speed of the communication terminal 110 to the log information that determines the moving speed of the communication terminal 110.

  In addition, the outlier detection unit 422 includes a communication environment for the log information when there is only one log information corresponding to the specific terminal identification information or among a plurality of log information classified for each terminal identification information. For the log information with the earliest information acquisition time, the moving speed of the communication terminal 110 cannot be determined by the above equation (1). When the moving speed of the communication terminal 110 at the position indicated by the specific log information cannot be determined, the outlier detection unit 422 does not have to determine the moving speed of the communication terminal 110 at the position. Based on the moving speed of the communication terminal 110 at the position indicated by the information, the moving speed of the communication terminal 110 at the position may not be determined. For example, the outlier detection unit 422 indicates the moving speed of the communication terminal 110 at the position indicated by the log information stored in the first row of the data table 300 using the log information stored in the second row of the data table 300. And determined to be the same as the moving speed of the communication terminal 110 at the position.

  The outlier detection unit 422 detects an outlier based on the moving speed of the communication terminal 110 by the following procedure, for example. When the moving speed of the communication terminal 110 is equal to or less than a first value (for example, 60 km / h), the outlier detection unit 422 exemplifies the first moving means (walking, bicycle, etc.). It is determined that the log information has been acquired while moving. When the moving speed of the communication terminal 110 is larger than the first value, the user of the communication terminal 110 is moving by the second moving means (which can be exemplified by an automobile, a railway, a high-speed railway, etc.). It is determined that log information has been acquired. Further, when the moving speed of the communication terminal 110 is greater than the second value (for example, 350 km / h), the outlier detection unit 422 determines that any error has occurred when acquiring the position information, and Log information is detected as an outlier.

  According to another embodiment, position information, communication environment information of a communication terminal, and terminal identification information for identifying each of the one or more communication terminals 110 are associated with at least a part of the one or more log information. If so, the outlier detection unit 422 detects specific log information as an outlier by the following procedure. In addition, it is preferable that log information is further matched with the information regarding the time when the communication environment information of the communication terminal was acquired.

  The outlier detection unit 422 first classifies the log information received from the log information acquisition unit 414 for each communication terminal 110 identified by the terminal identification information, based on the terminal identification information. The outlier detection unit 422 detects the set of log information as an outlier when the set of log information classified for each terminal identification information includes only log information indicating that communication is not possible. Good.

  The outlier detection unit 422, when log information indicating that communication is impossible is continuously included in a set of log information classified for each terminal identification information for a predetermined number of times. A set of log information may be detected as an outlier. The outlier detection unit 422 may detect all of one or more pieces of log information included in a set of log information as outliers, and communication is impossible among one or more pieces of log information included in the set of log information. Only the portion in which the log information indicating “” is continuously recorded for a predetermined number of times or more may be detected as an outlier.

  The outlier detection unit 422, when a set of log information classified for each terminal identification information, log information indicating that communication is not possible continues for a predetermined time, the set of log information Information may be detected as an outlier. The outlier detection unit 422 may detect all of one or more pieces of log information included in a set of log information as outliers, and communication is impossible among one or more pieces of log information included in the set of log information. Only a portion in which log information indicating 継 続 continues for a predetermined time or more may be detected as an outlier.

  According to still another embodiment, the outlier detection unit 422 uses the log information as an outlier when the position indicated by the position information included in the log information is outside a predetermined geographical range. May be detected. For example, when the statistical information generation unit 424 generates statistical information in Japan and the position information included in the log information acquired from the log information acquisition unit 414 indicates a position outside Japan, the outlier detection unit 422 May detect the log information as an outlier.

  The statistical information generation unit 424 receives log information from the log information acquisition unit 414 or the outlier detection unit 422. The statistical information generation unit 424 may receive, from the outlier detection unit 422, data from which log information detected as an outlier by the outlier detection unit 422 is excluded from the log information received from the communication terminal 110.

  The statistical information generation unit 424 generates statistical information related to the position of the communication environment based on the received one or more pieces of log information. The statistical information generation unit 424 generates statistical information related to the position for each item (can exemplify communication availability, radio wave status, communication quality, communication method, communication carrier, etc.) constituting the communication environment information. Good. The statistical information generation unit 424 may generate statistical information regarding the position for at least one of the items constituting the communication environment information.

  The statistical information generation unit 424 may generate statistical information using all of the received log information. The statistical information generation unit 424 uses the GPS information included in the log information to distinguish between log information indicating an indoor communication environment and log information indicating an outdoor communication environment, and generating statistical information for each. Good. The statistical information generation unit 424 may generate statistical information for each communication carrier. The statistical information generation unit 424 may generate statistical information for each communication method. The statistical information generation unit 424 may generate statistical information by excluding log information detected as an outlier by the outlier detection unit 422 from one or more pieces of log information acquired by the log information acquisition unit 414.

  The statistical information generation unit 424 generates statistical information related to the position of the communication environment, for example, according to the following procedure. First, the statistical information generation unit 424 classifies the received log information into one or more sets based on the position indicated by the position information included in each log information. The statistical information generation unit 424 may classify the log information so that the log information having the same position indicated by the position information included in the log information is in the same set. The statistical information generation unit 424 may classify the log information so that the log information included in the same geographical range at the position indicated by the position information included in the log information is in the same set.

  Next, the statistical information generation unit 424 generates statistical information for each of the one or more sets based on the log information included in each of the one or more sets. According to one embodiment, the communication environment indicated by the communication environment information can be expressed by a numerical value (a case where the communication environment is a radio wave intensity, a communication speed, a throughput, a latency, or the like can be exemplified). The statistical information generation unit 424 generates a representative value representing the communication environment. For example, at least one of the arithmetic average value, median value, mode value, maximum value, and minimum value of the communication environment is generated. Thereby, the information showing the geographical distribution situation of the information regarding the communication environment can be provided. The statistical information generation unit 424 may generate statistical information indicating the degree of data variation such as standard deviation. Thereby, information representing the stability of the communication environment can be provided.

  According to another embodiment, the statistical information generation unit 424 generates statistical information based on information related to communication availability. For example, the statistical information generation unit 424 calculates the ratio of the number of pieces of information indicating that communication is possible with respect to the number of pieces of information related to communication availability for each of one or more sets. Thereby, the information showing the connection rate in the same position or the same area can be provided.

  According to another embodiment, at least a part of one or more log information is associated with position information, information about the communication environment of the communication terminal, and information about the time when the information about the communication environment of the communication terminal is acquired. If it is, the statistical information generation unit 424 generates, as statistical information, information related to the temporal change of the communication environment at least at one part of one or more positions. The statistical information generation unit 424 may generate information regarding increase / decrease of log information indicating that communication is not possible before and after a specific time for an area around a specific position. For example, the statistical information generation unit 424 generates information related to increase / decrease of log information indicating that communication is not possible before and after the base station is installed in an area around the position where the base station is newly installed.

  The statistical information generation unit 424 includes, in each of the areas subject to statistical processing, an area where log information indicating that communication is disabled has decreased, an area where log information indicating that communication is disabled has increased, and log information indicating that communication is not possible May be classified into three areas where there is no increase / decrease. Thereby, for example, information representing an improvement trend of the communication environment can be provided. The statistical information generation unit 424 determines whether or not at least one piece of information indicating that communication is not possible is included for each of one or more sets, and includes at least one piece of information indicating that communication is not possible. Communication impossibility may be selected as a representative value of information regarding whether or not a set of communication is possible.

  The statistical information generation unit 424 may determine a display method according to the value of the statistical information for each of the one or more sets. The statistical information generation unit 424 may give information related to the display method for each of the one or more sets. For example, the statistical information generation unit 424 classifies the position or area that is subject to statistical processing into a plurality of sections based on the magnitude of the value of the statistical information. Each of the plurality of sections has a one-to-one correspondence with each of the plurality of display methods. Examples of the display method include the shape, color, and icon type when output to a display device such as a display.
