In the present embodiment, the information collection server 120 includes a communication control unit 412, a log information acquisition unit 414, and a log information analysis unit 420. The log information analysis unit 420 includes an outlier detection module 422 and a statistical information generation module 424. The statistical information generation module 424 may be an example of a statistical information generation unit.

  Each unit of the information collection server 120 may be realized by hardware, may be realized by software, or may be realized by a combination of hardware and software. Further, the computer may function as a part of the information collection server 120 by executing the program. The program may be stored in a computer-readable medium, or may be stored in a storage device connected to a network.

  A program that is installed in a computer and causes the computer to function as a part of the information collection server 120 according to this embodiment includes a module that defines the operation of each unit of the information collection server 120. These programs or modules work on the CPU or the like to cause the computer to function as each unit of the information collection server 120 or cause the computer to execute the information processing method in the information collection server 120. The information processing described in these programs functions as a specific means in which software and various hardware resources of the information collection server 120 cooperate with each other by being read by a computer. And the information collection server 120 according to a use purpose can be constructed | assembled by implement | achieving the calculation or processing of the information according to the use purpose of the computer in this embodiment by these specific means.

  The communication control unit 412 controls communication between the information collection server 120 and one or more communication terminals 110. The communication control unit 412 may be a communication interface. The communication control unit 412 transmits log information received from one or more communication terminals 110 to the log information acquisition unit 414. The communication control unit 412 may transmit an instruction from the user of the information collection server 120 to the statistical information generation module 424. The log information acquisition unit 414 acquires one or more log information from one or more communication terminals 110. The log information acquisition unit 414 transmits the acquired log information to at least one of the outlier detection module 422 and the statistical information generation module 424.

  The log information analysis unit 420 analyzes the log information and generates information related to the communication status in at least a part of one or more positions. In the present embodiment, the log information analysis unit 420 generates statistical information related to the position of the communication environment as information related to the communication status. The log information analysis unit 420 may generate statistical information using all of the log information acquired by the log information acquisition unit 414, and other log information indicates from the log information acquired by the log information acquisition unit 414. Statistical information may be generated by excluding log information indicating a value deviating from the value.

  In one embodiment, the log information analysis unit 420 distinguishes log information indicating an indoor communication environment from log information indicating an outdoor communication environment, and generates statistical information for each. In another embodiment, the log information analysis unit 420 generates statistical information by excluding log information indicating an indoor communication environment from the log information acquired by the log information acquisition unit 414.

  The outlier detection module 422 receives one or more pieces of log information from the log information acquisition unit 414. The outlier detection module 422 detects, as an outlier, log information indicating a value that is out of the value indicated by the other log information from the received log information. Thereby, the accuracy of analysis can be improved. The outlier detection module 422 adds information indicating an outlier to the log information detected as an outlier, and then sends all of the log information received from the log information acquisition unit 414 to the statistical information generation module 424. May be sent. The outlier detection module 422 may transmit the log information received from the log information acquisition unit 414 excluding the log information detected as the outlier to the statistical information generation module 424.

  The outlier detection module 422 may detect an outlier based on an average value and a standard deviation of a target to be detected as an outlier. For example, an outlier is detected when the average value is not included in the range of several times the standard deviation (for example, 2 times or 3 times). The outlier detection module 422 may detect an outlier based on a comparison with a predetermined value. The outlier detection module 422 may determine a target to be detected as an outlier according to the contents of statistical processing in the statistical information generation module 424.

  According to one embodiment, the position information, the communication environment information of the communication terminal, and the information regarding the GPS accuracy of the GPS information acquired by the communication terminal at the time when the position information is acquired for at least a part of the one or more log information Are associated with each other, the outlier detection module 422 detects specific log information as an outlier by the following procedure. The outlier detection module 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 module 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 module 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 module 424 can generate statistical information mainly using communication environment information in a place where radio waves are easily received such as outdoors or near a window. 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 module 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 module 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 module 422 detects specific log information as an outlier by the following procedure. The outlier detection module 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 module 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 module 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 module 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 module 424 can generate statistical information regarding each case.

The outlier detection module 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 module 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 module 422 communicates 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 module 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 module 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.

  It should be noted that the outlier detection module 422 uses the 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 module 422 does not need 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 module 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 module 422 detects an outlier based on the moving speed of the communication terminal 110, for example, according to the following procedure. The outlier detection module 422 determines that the log information has been acquired when the user of the communication terminal 110 is moving by the first moving means when the moving speed of the communication terminal 110 is equal to or lower than the first value. To do. The first value is, for example, 30 to 60 km / h. Examples of the first moving means include walking and bicycles. If the moving speed of the communication terminal 110 is greater than the first value, it is determined that the log information has been acquired when the user of the communication terminal 110 is moving by the second moving means). Examples of the second moving means include automobiles, railways, and high-speed railways. Further, when the moving speed of the communication terminal 110 is greater than the second value, the outlier detection module 422 determines that any error has occurred when acquiring the position information, and detects the log information as an outlier. To do. The second value is larger than the first value, for example, 120 to 350 km / h.

  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 module 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 module 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 module 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 module 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 module 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 module 422, when a set of log information classified for each terminal identification information continues log information indicating that communication is not possible for a predetermined time, the set of log information Information may be detected as an outlier. The outlier detection module 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 module 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 module 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 module 422 May detect the log information as an outlier.

  The statistical information generation module 424 receives an instruction from the user of the information collection server 120 via the communication control unit 412. The statistical information generation module 424 receives one or more pieces of log information from the log information acquisition unit 414 or the outlier detection module 422. The statistical information generation module 424 is a data in which the log information detected as an outlier by the outlier detection module 422 is excluded from the log information received by the log information acquisition unit 414 from the communication terminal 110 from the outlier detection module 422. You may receive.

  The statistical information generation module 424 generates statistical information related to the communication environment based on at least a part of one or more pieces of log information received from the log information acquisition unit 414 or the outlier detection module 422. The statistical information generation module 424 may generate statistical information regarding the position of the communication environment. The statistical information regarding the position of the communication environment may be statistical information of the communication environment in the position or area designated by the user of the information collection server 120.

  For example, the statistical information generation module 424 calculates the statistical value of the communication environment information for each communication carrier in Japan using the communication environment information included in each of the one or more log information. Statistical information can be generated. In addition, the statistical information generation module 424 uses the communication environment information included in each of the one or more log information to calculate the statistical value of the communication environment information outside Japan for each communication carrier in Japan. Statistical information can be generated when a roaming service is used.

  The statistical information generation module 424 may generate statistical information regarding the position for each item constituting the communication environment information. The statistical information generation module 424 may generate statistical information regarding the position for at least one of the items constituting the communication environment information. The statistical information generation module 424 may determine an item for which statistical information should be generated in accordance with an instruction from the user of the information collection server 120. The items constituting the communication environment information are, for example, communication availability, radio wave status, communication quality, communication method, communication carrier, and the like.

  When the items constituting the communication environment information can be expressed numerically, the statistical information generation module 424 uses at least one of the arithmetic average value, median value, mode value, maximum value, and minimum value of the item as the statistical information. You may generate one. The statistical information generation module 424 may generate information representing the degree of data variation such as variance and standard deviation as statistical information. Thereby, information representing the stability of the communication environment can be provided.

  If the items constituting the communication environment information cannot be expressed numerically, the statistical information generation module 424 indicates, as statistical information, log information indicating that the item indicates specific information with respect to the number of log information for which statistical information is to be generated. A percentage of the number may be generated. For example, when an item for which statistical information is to be generated is communication availability, the item indicates information indicating that communication is possible or information indicating that communication is not possible, and cannot be expressed numerically. In this case, for example, the statistical information generation module 424 calculates the ratio of the number of log information indicating information that communication is possible to the number of log information for which statistical information is to be generated (sometimes referred to as a connection rate). Generate as

  The statistical information generation module 424 is based on log information in which position information, information on the communication environment of the communication terminal 110 at the position, and information on the time when the information on the communication environment of the communication terminal 110 is acquired are associated with each other. Thus, as statistical information, information regarding a change over time of the communication environment at a specific position or area may be generated. For example, the statistical information generation module 424 generates information on increase / decrease of log information indicating that communication is possible or impossible before and after a specific time for an area around a specific position. For example, the specific position is a position where a base station is newly established, and the specific time is a time when the base station is installed. Thereby, for example, information representing an improvement trend of the communication environment can be provided.

  The statistical information generation module 424 may classify the position or area that is the target of statistical processing into a plurality of sections based on the value of the statistical information. Further, the statistical information generation module 424 may determine a display method according to the value of the statistical information. Examples of the display method include the shape, color, icon type, and the like when the statistical information is output to a display device such as a display.

  For example, when generating information related to increase / decrease of log information indicating that communication is possible or not possible before and after a specific time for an area around a specific position, the statistical information generation module 424 increases or decreases log information indicating that communication is not possible. Depending on the width, each of the positions or areas subject to statistical processing includes an area where log information indicating that communication is disabled has decreased, an area where log information indicating that communication is disabled has been increased, and log information indicating that communication is not possible May be classified into three areas where there is no increase / decrease. When displaying the statistical information on the map, the statistical information generation module 424 indicates the area where the log information indicating that communication is not possible is reduced in red, the area where the log information indicating that communication is not increased is indicated in blue, and communication is not possible. It may be determined that an area where there is no increase / decrease in the log information indicating is shown in yellow.

  The statistical information generation module 424 classifies one or more pieces of log information received from the log information acquisition unit 414 or the outlier detection module 422 into one or more sets, and sets one or more sets for each of the one or more sets or a specific set. Statistical information may be generated based on log information included in each or a specific group. The statistical information generation module 424 may classify one or more pieces of log information into one or more sets based on at least one piece of information included in the log information. The statistical information generation module 424 may determine a specific set for which statistical information should be generated in accordance with an instruction from the user of the information collection server 120.

  The statistical information generation module 424 may determine a representative value representing the group based on log information included in each of the one or more groups or a specific group, and generate statistical information based on the representative value. Good. For example, when communication environment information for generating statistical information can be expressed as a numerical value, the statistical information generation module 424 uses the arithmetic average value, median value, mode value, maximum value, and minimum value of the communication environment information as representative values. Generate at least one of the values. Further, when the communication environment information for generating the statistical information cannot be expressed as a numerical value, the statistical information generation module 424 determines the representative value according to a predetermined rule.

  For example, when determining a representative value of information regarding whether communication is possible in a specific group, the statistical information generation module 424 indicates that communication is not possible for each piece of log information included in the group for which a representative value is to be determined. It is determined whether or not is included. When at least one piece of log information including information indicating that communication is not possible is included in the log information included in the group for which the representative value is to be determined, the communication is used as the representative value of the information regarding the communication availability of the group. Select the disabling information. If the log information included in the group for which the representative value is to be determined does not include log information including information indicating that communication is not possible, communication is possible as the representative value of information regarding whether communication of the group is possible. Select information.

  In one embodiment, the statistical information generation module 424 classifies the one or more log information into one or more sets based on the position indicated by the position information included in each of the one or more log information. The statistical information generation module 424 classifies the log information so that the log information having the same position indicated by the position information or the log information included in the area having the same position indicated by the position information is in the same set. Good.

  The statistical information generation module 424 generates statistical information related to the communication environment for each of the groups classified as described above or a specific group among the groups classified as described above. Thereby, the information showing the geographical distribution situation of the information regarding the communication environment can be provided. For example, the statistical information generation module 424 generates the connection rate in the specific position or area based on the information regarding the availability of communication of the log information classified into the specific position or area, so that the geographical rate of the connection rate Distribution situation can be provided.

  In another embodiment, the statistical information generation module 424 acquires position information indicating the position of the communication terminal 110 and information regarding the time when the information regarding the communication environment of the communication terminal 110 is acquired, which is included in each of the one or more pieces of log information. Based on the time information and terminal identification information for identifying the communication terminal 110, the one or more log information is classified into one or more sets. More specifically, the statistical information generation module 424 first classifies the log information subject to statistical processing into one or more sets based on the terminal identification information included in each piece of log information subject to statistical processing. To do. Next, the statistical information generation module 424 moves the communication terminal 110 when the position information and the communication environment information are acquired from the log information included in each of the one or more sets classified for each terminal identification information. Based on whether or not, it is classified into one or more sets of one or more log information continuous in time. The statistical information generation module 424 determines whether or not the communication terminal 110 has moved when the position information and communication environment information included in the specific log information is acquired based on the position information and acquisition time information of the log information. May be determined.

  The statistical information generation module 424 generates statistical information related to the communication environment for each of the groups classified as described above or a specific group among the groups classified as described above. The statistical information generation module 424 may determine a representative value representing the group for at least a part of the group classified as described above, and generate statistical information based on the representative value. The statistical information generation module 424 may generate statistical information using the representative values of the communication environment information in some groups and the communication environment information of log information included in other groups.

  In particular, it is preferable that the statistical information generation module 424 determines a representative value that represents a set of log information that the communication terminal 110 has not moved when the position information and the communication environment information are acquired. . When the communication terminal 110 is not moving, the number of log information per unit time may vary greatly depending on the OS of the communication terminal 110. For example, when the OS of the communication terminal 110 is an OS that does not restrict the operation of the program even if the program is in the background state, the program of the communication terminal 110 is in the background state when the program is in the background state. The number of log information per unit time is larger than in the case of an OS that restricts the operation of.

  Here, when it is determined that the communication terminal 110 is not moving, the communication terminal 110 can be regarded as being used or placed at a specific position or area. As a specific position or area, a home, a workplace, etc. can be illustrated. The user of the communication terminal 110 often has a communication terminal having a good communication environment at home, work, etc., and the program for acquiring communication environment information is in the background at home, work, etc. Probability is high. Therefore, the difference in OS of the communication terminal 110 may affect the accuracy of statistical information generated by the statistical information generation module 424. However, for the set of log information that the communication terminal 110 has not moved when the position information and the communication environment information are acquired, a representative value that represents the set is determined, and statistical information is obtained using the representative value. By generating, the influence which the difference in OS of the communication terminal 110 has on the accuracy of statistical information can be suppressed.

  In another embodiment, the statistical information generation module 424 classifies one or more log information into one or more sets based on GPS information included in the log information. More specifically, the statistical information generation module 424 determines whether the GPS accuracy included in one or more log information to be subjected to statistical processing is larger than a predetermined value, for example. The above log information is classified into two groups, a group having a GPS accuracy equal to or lower than a predetermined value and a group having a GPS accuracy larger than a predetermined value.

  Thereby, one or more pieces of log information can be classified into log information indicating an indoor communication environment and log information indicating an outdoor communication environment. The statistical information generation module 424 generates statistical information related to the communication environment for each of the groups classified as described above or a specific group among the groups classified as described above.

  In another embodiment, the statistical information generation module 424 sets one or more pieces of log information into one or more sets based on information indicating the communication method used when acquiring information about the communication environment included in the log information. Classify. The statistical information generation module 424 generates statistical information related to the communication environment for each of the groups classified as described above or a specific group among the groups classified as described above.

  In recent years, the communication terminal 110 supports not only mobile communication methods such as 3G, 4G, and LTE, but also wireless LAN methods such as WiFi (registered trademark) or wireless MAN methods such as WiMAX (registered trademark). There may be. However, by classifying one or more pieces of log information for each communication method, it is possible to generate statistical information regarding each communication environment of the mobile communication method such as the 3G method, the 4G method, and the LTE method.

  If the specific log information does not include information indicating the communication method used at the time of acquisition of information related to the communication environment, the statistical information generation module 424, based on other information included in the log information, A communication method may be determined. For example, when the log information includes information related to network latency as communication environment information, the statistical information generation module 424 obtains information related to the latency based on the information related to latency included in the log information. Determine the communication method used at the time.

  In the log information, when the information about the communication environment and the information for identifying the model of the communication terminal 110 used when acquiring the information about the communication environment are further associated, the statistical information generation module 424 The information for identifying the model of the terminal 110 is used to acquire information on the communication method corresponding to each model of the communication terminal 110, and the communication terminal 110 is based on the information about the latency included in the log information. You may select the communication system used at the time of the acquisition of the information regarding a communication environment from the communication systems with which a model respond | corresponds. Thereby, a communication system can be determined with high accuracy.

The one or more log information is classified into one or more sets based on the acquisition time information regarding the terminal and terminal identification information for identifying the communication terminal 110. More specifically, the log information classification unit 512 classifies the received one or more pieces of log information into one or more sets, for example, according to the following procedure.

  First, the log information classification unit 512 rearranges the received one or more log information according to the time indicated by the acquisition time information included in each of the received one or more log information. Next, the log information classification unit 512 classifies the one or more log information for each terminal identification information based on the terminal identification information included in each of the one or more log information.

Based on whether or not, it is classified into one or more sets of one or more log information continuous in time.

  For example, when the terminal identification information is updated every other day, the log information classification unit 512 classifies the log information to be subjected to statistical processing into the pieces of log information to be subjected to statistical processing by classifying the log information to be subjected to statistical processing. And classify into a set of log information for one day for each communication terminal 110.

For example, (1) log information from when the user of the communication terminal 110 returns home to work the next morning, (2) log information until the user of the communication terminal 110 goes to work from home, ( 3) Log information while the user of the communication terminal 110 is working at the workplace, (4) Log information while the user of the communication terminal 110 is out of the workplace for lunch, (5) of the communication terminal 110 The information is further classified into six groups: log information while the user is working at work after lunch, and (6) log information until the user of the communication terminal 110 returns home from work.

  In another embodiment, the log information classification unit 512 classifies one or more log information into one or more sets based on GPS information included in the log information. More specifically, the log information classification unit 512 determines whether the GPS accuracy included in one or more pieces of log information to be subjected to statistical processing is larger than a predetermined value, for example. The above log information is classified into two groups, a group having a GPS accuracy equal to or lower than a predetermined value and a group having a GPS accuracy larger than a predetermined value.

  In another embodiment, the log information classification unit 512 sets one or more pieces of log information into one or more sets based on information indicating the communication method used when acquiring information related to the communication environment included in the log information. Classify. The log information classification unit 512 may transmit log information that does not include information regarding the communication method to the communication method determination unit 516.

  The representative value generation unit 514 has one or more sets of one or more groups classified by the log information classification unit 512 or one or more specific groups based on log information included in each of the one or more groups or the specific group. A representative value representative of information about the communication environment of each set or a specific set is generated. The representative value generation unit 514 may determine a specific set for which a representative value is to be generated in accordance with an instruction from the user of the information collection server 120.

  When the communication environment information for generating the statistical information can be expressed numerically, the representative value generation unit 514 uses the arithmetic average value, median value, mode value, maximum value, and minimum value of the communication environment information as the representative value. At least one may be generated. On the other hand, when the communication environment information for generating the statistical information cannot be expressed as a numerical value, the representative value generation unit 514 may determine the representative value according to a predetermined rule.

  As an example of the predetermined rule, the ratio of the number of log information in which the communication environment information for generating statistical information indicates specific information with respect to the number of one or more log information included in the specific group It can be considered to be a representative value. As another example of the predetermined rule, one or more pieces of log information in which communication environment information for generating statistical information indicates specific information among one or more pieces of log information included in a specific group. However, if it is included, the specific information may be used as a representative value.

  The communication method determination unit 516 receives one or more pieces of log information from the log information acquisition unit 414, the outlier detection module 422, or the log information classification unit 512. The communication method determination unit 516 determines the communication method when there is log information that does not include information regarding the communication method used when acquiring information regarding the communication environment in the received one or more pieces of log information. . The communication method determination unit 516 may determine whether or not to determine the communication method according to an instruction from the user of the information collection server 120.

  When the log information that does not include the information related to the communication method includes the information related to the latency of the network, the communication method determination unit 516 may determine the communication method based on the information related to the latency. For example, when the latency is smaller than a predetermined value, the communication method determination unit 516 may exemplify the first communication method (LTE method, 4G method, etc.) as the communication method used when acquiring information related to the communication environment. Can be determined.) On the other hand, when the latency is equal to or greater than a predetermined value, the communication method determination unit 516 can exemplify the second communication method (3G method or the like) as the communication method used when acquiring information related to the communication environment. .)

  When the log information not including information related to the communication method includes information related to network latency and information for identifying the model of the communication terminal 110 used when acquiring information related to the communication environment, the communication method determination unit 516 May determine the communication method used at the time of acquiring information related to the communication environment according to the following procedure. First, the communication method determination unit 516 refers to the model information storage unit 518 based on the information for identifying the model of the communication terminal included in the log information, and the communication terminal used when acquiring information related to the communication environment A communication method supported by 110 is extracted. Next, the communication method determination unit 516 determines the communication method used at the time of acquiring information related to the communication environment based on the extracted information related to the communication method and latency.

  For example, when it is specified that the communication terminal is compatible with both the 3G method and the LTE method based on the model identification information of the communication terminal 110 included in a certain log information, the latency is a predetermined value. If it is smaller, it is determined that the communication method used at the time of obtaining information about the communication environment is the LTE method. On the other hand, when the latency is equal to or greater than a predetermined value, it is determined that the communication method used when acquiring information related to the communication environment is the 3G method. In addition, when it is specified that the communication terminal supports only the 3G system based on the model identification information of the communication terminal 110 included in certain log information, it is used when acquiring information about the communication environment. The determined communication method is determined to be the 3G method.

  The model information storage unit 518 supports one or more model identification information for identifying each model of the communication terminal and a communication method supported by the communication terminal of the model identified by the one or more model identification information. Store with attachments. The model information storage unit 518 receives information for identifying the model of the communication terminal from the communication method determination unit 516. The model information storage unit 518 compares information for identifying the model of the communication terminal with the model identification information stored in the communication method determination unit 516. The model information storage unit 518 extracts the communication method associated with the model identification information that matches the information for identifying the model of the communication terminal. The model information storage unit 518 transmits the extracted communication method to the communication method determination unit 516.

  The statistical processing unit 520 receives information serving as a population for generating statistical information from the log information acquisition unit 414, the outlier detection module 422, the log information classification unit 512, the representative value generation unit 514, or the communication method determination unit 516. Receive. The statistical processing unit 520 receives an instruction from the user of the information collection server 120 via the communication control unit 412.

  The statistical processing unit 520 may generate statistical information regarding the position of the communication environment based on each representative value of one or more sets classified by the log information classification unit 512. The statistical processing unit 520 may generate statistical information using the representative value of the communication environment information in some groups and the communication environment information of log information included in other groups.

  The statistical processing unit 520 generates statistical information in accordance with an instruction from the user of the information collection server 120. The statistical processing unit 520 may determine an item for which statistical information should be generated in accordance with an instruction from the user of the information collection server 120. For example, the statistical processing unit 520 generates statistical information regarding the position of the communication environment for the communication method specified by the user of the information collection server 120 based on the representative values of one or more sets.

  When the items constituting the communication environment information can be expressed by numerical values, the statistical processing unit 520 uses, as the statistical information, at least one of an arithmetic average value, median value, mode value, maximum value, and minimum value of the item. May be generated. The statistical processing unit 520 may generate information representing the degree of variation in data such as variance and standard deviation as statistical information.

  When the items constituting the communication environment information cannot be expressed numerically, the statistical processing unit 520 displays, as statistical information, log information indicating that the item indicates specific information with respect to the number of log information for which statistical information is to be generated. A percentage of the numbers may be generated. For example, when an item for which statistical information is to be generated is communication availability, the item indicates information indicating that communication is possible or information indicating that communication is not possible, and cannot be expressed numerically. In this case, for example, the statistical information generation module 424 generates, as statistical information, the ratio of the number of log information indicating information that communication is possible to the number of log information for which statistical information is to be generated.

  The statistical processing unit 520 stores the generated statistical information in the statistical information storage unit 522. The statistical processing unit 520 may store the generated statistical information and information regarding the display method of the statistical information in association with each other. Examples of the information relating to the display method include the shape, color, icon type, and the like when the statistical information is output to a display device such as a display. The statistical information storage unit 522 stores information received from the statistical processing unit 520.

  FIG. 6 schematically shows an example of the data table 600 stored in the model information storage unit 518. The data table 600 stores the model name 610 and the corresponding communication method 620 in association with each other. The model name 610 may be an example of model identification information.
