  The terminal location information generation unit 610 receives from the log information acquisition unit 510 one or more pieces of log information in which the terminal identification information of the wireless terminal is associated with the relay device identification information. The terminal location information generation unit 610 generates terminal location information of a plurality of wireless terminals based on the received log information and information stored in the relay device information storage unit 126.

  For example, the terminal location information generation unit 610 transmits an extraction condition for extracting the location information 220 associated with the relay device identification symbol 210 included in the log information to the relay device information extraction unit 540. The relay device information extraction unit 540 refers to the relay device information storage unit 126 using the relay device identification symbol 210 as a key, and extracts the relay device position information 220 identified by the relay device identification information included in the log information. .

Judge whether or not. If the same user determination unit 620 determines that the correlation between the terminal attribute information of two or more wireless terminals is greater than a predetermined value, the same user determination unit 620 determines that the two or more wireless terminals are possessed by the same user. .

  For example, the same user determination unit 620 analyzes the correlation of terminal position information of two or more wireless terminals over time (may be referred to as a movement history), and the correlation of movement histories of two or more wireless terminals is determined in advance. When it is determined that the value is larger than the predetermined value, it is determined that two or more wireless terminals are possessed by the same user. The same user determination unit 620 may store the determination result in the terminal information storage unit 124 in association with the terminal identification information.

  The same user determination unit 620 may periodically analyze the correlation of the terminal attribute information of two or more wireless terminals. Thereby, the same user determination part 620 can detect the change of the owner of a specific radio | wireless terminal.

Examples of time zones include weekday / holiday distinction, morning / day / evening / night / midnight-early morning distinction, and the like.

  For example, the terminal attribute information generation unit 630 uses the log information acquired from the log information acquisition unit 510, and for each of the plurality of wireless terminals, the position information 220 and attributes of the relay device that has received the probe request from the wireless terminal. For at least one of the information 230, the appearance frequency or the appearance probability is calculated. The terminal attribute information generation unit 630 determines the attribute of the user of the wireless terminal based on the calculated appearance frequency or appearance probability.

  For example, the terminal attribute information generation unit 630 determines the position information 220 or the attribute information 230 whose appearance frequency or appearance probability is larger than a predetermined value as the attribute of the user of the wireless terminal. The terminal attribute information generation unit 630 may determine the position information 220 or the attribute information 230 whose appearance frequency or appearance probability is smaller than a predetermined value as the attribute of the user of the wireless terminal.

  The terminal attribute information generation unit 630 may generate terminal attribute information based on the determination result of the terminal position determination module 634. The terminal attribute information generation unit 630 uses the determination result of the terminal position determination module 634 to grasp local areas (stores, schools, workplaces, and the like that are frequently used by wireless terminal users). Can do.

  For example, the terminal attribute information generation unit 630 uses, for each of a plurality of wireless terminals, the log information that the determination result of the terminal position determination module 634 is “in area”, and the relay that has received the probe request from the wireless terminal The appearance frequency or the appearance probability is calculated for at least one of the device position information 220 and the attribute information 230. The terminal attribute information generation unit 630 determines the attribute of the user of the wireless terminal based on the calculated appearance frequency or appearance probability. Thereby, the terminal attribute information generation unit 630 can determine a local area that is frequently used by users of wireless terminals. The terminal attribute information generation unit 630 determines the access point attribute information 230 arranged in the local area frequently used by the wireless terminal user as the attribute of the wireless terminal user.

  The terminal attribute information generation unit 630 uses, for each of the plurality of wireless terminals, the log information that the determination result of the terminal position determination module 634 is “out of area”, and the relay device that has received the probe request from the wireless terminal. The appearance frequency or the appearance probability may be calculated for at least one of the position information 220 and the attribute information 230. Thereby, the terminal attribute information generation unit 630 can determine the commuting route, the commuting route, the affiliation organization, the working time, the residence area, and the like of the user of the wireless terminal. The terminal attribute information generation unit 630 determines information such as a commuting route, a commuting route, a belonging organization, a working time, and a residence area of the wireless terminal user as attributes of the wireless terminal user.

  The statistical processing module 632 refers to the information stored in the relay device information storage unit 126, and determines each of the plurality of wireless terminals based on at least one of terminal identification information and relay device identification information included in the plurality of log information. , Statistical information on at least one of user positions and attributes of a plurality of wireless terminals is generated. Details of the statistical processing module 632 will be described later.

  Based on the terminal identification information, the relay device identification information, and the information on the radio wave intensity, the terminal position determination module 634 allows each of the plurality of wireless terminals that transmitted each of the plurality of probe requests to select one of the plurality of local areas. It is determined whether or not it exists within the range. Details of the terminal position determination module 634 will be described later.

  FIG. 7 schematically shows an example of the statistical processing module 632. In the present embodiment, the statistical processing module 632 includes a statistical information calculation unit 710, a frequent information extraction unit 720, and a statistical information generation unit 730.

  The statistical information calculation unit 710 receives a plurality of log information from the log information acquisition unit 510. The statistical information calculation unit 710 calculates the appearance frequency or the appearance probability of at least one of the terminal position information and the relay device identification information for each of the plurality of wireless terminals. The statistical information calculation unit 710 transmits the calculated appearance frequency or appearance probability to the frequent appearance information extraction unit 720.

  The frequent information extraction unit 720 determines whether the appearance frequency or the appearance probability calculated by the statistical information calculation unit 710 is greater than a predetermined value. The frequent appearance information extraction unit 720 extracts relay device identification information or terminal location information for which it is determined that the appearance frequency or the appearance probability is greater than a predetermined value. The frequent information extraction unit 720 transmits the extraction result to the statistical information generation unit 730.

  The statistical information generation unit 730 transmits the relay device identification information extracted by the frequent information extraction unit 720 to the relay device information extraction unit 540, and is identified by the relay device identification information extracted by the frequent information extraction unit 720. At least one of position information and attribute information of the device is acquired. The statistical information generation unit 730 includes, for each wireless terminal, the appearance frequency or appearance probability of the relay device identification information calculated by the statistical information calculation unit 710, and the position information and attribute information extracted by the relay device information extraction unit 540. By associating with at least one, statistical information regarding at least one of the position and attribute of the user of the wireless terminal is generated.

  According to the present embodiment, information on a place where a user of the wireless terminal is likely to pass or visit during a specific period (for example, weekday morning, noon, night, holiday, etc.) and attributes of the place are obtained. By associating, the attribute of the user of the wireless terminal can be specified. Similarly, the frequency information extracting unit 720 is improved so as to extract the relay device identification information that the appearance frequency or appearance probability is determined to be smaller than a predetermined value, so that the user of the wireless terminal passes or visits The attribute of the user of the wireless terminal may be specified from information on a place where there is a low possibility of doing so.

  In the present embodiment, the statistical processing module 632 uses the frequent information extraction unit 720 to determine whether the appearance frequency or the appearance probability calculated by the statistical information calculation unit 710 is greater than a predetermined value. Explained the case. However, the statistical processing module 632 is not limited to this embodiment. The statistical processing module 632 may determine whether or not the appearance frequency or the appearance probability calculated by the statistical information calculation unit 710 is smaller than a predetermined value.

  FIG. 8 schematically shows an example of the terminal position determination module 634. In the present embodiment, the terminal position determination module 634 includes a continuous log information generation unit 810, a log information classification unit 820, a distribution calculation unit 830, and a classification reference adjustment unit 840. The log information classification unit 820 may be an example of a terminal type unit.

  The continuous log information generation unit 810 extracts temporally continuous log information (sometimes referred to as continuous log information) from a plurality of log information. Thereby, several log information can be handled for every action of the user of a radio | wireless terminal. Specifically, the terminal identification information and the relay device identification information are the same among at least some of the plurality of log information based on the terminal identification information, the relay device identification information, and the information related to the reception date or time. One or more pieces of log information whose reception date / time or reception time is temporally continuous are extracted. The continuous log information generation unit 810 generates one or more continuous log information composed of the extracted one or more log information.

  The log information classification unit 820 classifies at least a part of the plurality of log information into a plurality of groups based on the terminal identification information, the information on the radio wave intensity, the information on the reception date / time or the reception time, and a predetermined classification standard. To do. The classification method into a plurality of groups is not particularly limited. For example, a radio terminal that exists in the local area and a radio that exists outside the local area due to the strength of the radio wave intensity requested by the probe. It is conceivable to classify the terminal into two types. The classification result by the log information classification unit 820 may be an example of a user attribute.

  Other classification methods include radio terminals that exist within the local area and radios that exist outside the local area based on the strength of the radio wave intensity required by the probe and the duration of the radio wave intensity. It is possible to classify into two groups with the terminal. By taking into account the duration of the state in which the radio field strength is high, it is possible to suppress an error in judgment due to fluctuations in the radio field intensity.

  For example, the log information classifying unit 820 analyzes each of the one or more pieces of continuous log information, and the time when a probe request having a radio field strength greater than a predetermined radio field strength is continuously received is determined in advance. When it is determined that the time is longer than the time, the log request included in the continuous log information may be transmitted from a wireless terminal that exists within the local area where each of the one or more relay apparatuses is arranged. Into the first group. On the other hand, the log information classifying unit 820 analyzes each of the one or more pieces of continuous log information, and the time during which a probe request having a radio field intensity greater than a predetermined radio field intensity is continuously received is determined in advance. When it is determined that it is not longer than the time, the log information included in the continuous log information is classified into a second group related to a probe request that may be transmitted from a wireless terminal that exists outside the range of the local area.

  The log information classification unit 820, for example, the ratio of the number of log information whose radio wave intensity is larger than a predetermined radio wave intensity among the log information included in the continuous log information with respect to the number of log information included in the continuous log information However, if it is determined that the probe request is greater than the predetermined value, it may be determined that a probe request having a radio field strength greater than the predetermined radio field strength has been continuously received. Thereby, the erroneous detection by the fluctuation | variation of radio field intensity can be suppressed.

  An example of a method for classifying log information into two will be described using a specific example. For a specific day, the access point 102 receives a probe request with an RSSI of −60 dB or less from the wireless terminal 22 in the period from 08:00 to 22:00, and the RSSI from the wireless terminal 24 is −60 dB or less. Probe requests are received in a period from 12:15 to 12:55 and a period from 17:35 to 17:37 minutes, and a probe request from the wireless terminal 62 with an RSSI of −60 dB or less is received from 12:05 to 12 Suppose that it is received in the period: 07, the period 12:50 to 12:52, and the period 18:05 to 18:07.

  The log information classification unit 820 extracts log information corresponding to a probe request received continuously for 10 minutes or more, for example, as a probe request that may be transmitted from a wireless terminal existing in the local area. As a result, the probe request from the wireless terminal 22 received in the period from 08:00 to 22:00 and the probe request received from the wireless terminal 24 in the period from 12:15 to 12:55 are extracted. The log information classification unit 820 classifies the log information corresponding to the two extracted probe requests into the first group. On the other hand, the log information classification unit 820 classifies other log information into the second group.

  As another classification method, classification into three or more groups may be performed based on the strength of the radio wave intensity requested by the probe and the duration of the radio wave intensity being strong. For example, the log information classifying unit 820 includes, for each of the plurality of wireless terminals, the time that has existed in each range of the plurality of local areas based on the information regarding the reception date and time or the reception time and the determination result of the terminal position determination module 634. And a plurality of wireless terminals are classified according to the time within each range of the plurality of local areas.

  Taking the case where the probe request received at the access point 102 is classified as an example, the radio wave intensity of the probe request is strong, and a long time (12 hours or more, a time longer than the business hours of the store, etc. can be exemplified. .), The wireless terminal that has transmitted the probe request is likely to be an OA device or the like existing in the store 12. When the radio wave intensity of the probe request is strong and has been received for several hours, the wireless terminal that has transmitted the probe request is likely to be an employee of the store 12 or the like. These data become noise when focusing on the customer's behavior history.

  On the other hand, when the radio wave intensity of the probe request is relatively strong and has been received for several minutes to several hours, the wireless terminal that has transmitted the probe request is likely to be a wireless terminal of a store visitor. If the probe request from the wireless terminal is relatively weak, or if the probe request from the wireless terminal is relatively strong, but received only for a few seconds to a few minutes, the probe request is transmitted. The wireless terminal is likely to be a wireless terminal of a passerby who has passed outside the store.

  In this way, one or more continuous log information is classified into three or more groups using one or more thresholds relating to the strength of the radio wave strength of the probe request and one or more thresholds relating to the duration of the radio wave strength being strong. May be. Thereby, log information that becomes noise when log information is processed can be removed in advance.

  Based on the information on the radio field intensity and the relay apparatus identification information, the distribution calculation unit 830 determines the radio field intensity of the probe request received at each of the one or more relay apparatuses for each of the one or more relay apparatuses. A probability distribution or a normalized frequency distribution with as a variable is calculated.

  The classification reference adjustment unit 840 adjusts the classification reference based on the probability distribution or the normalized frequency distribution of at least two groups of the plurality of groups. The classification reference adjustment unit 840 adjusts the value of the radio field strength that is predetermined as the classification reference so that the error of the classification result by the log information classification unit 820 matches the predetermined condition.

  For example, when adjusting the classification criteria based on the probability distribution of two groups or the normalized frequency distribution, data that should originally be included in the first group is not included in the first group (ie, The probability that an error of being included in the second group is smaller than the first threshold and data that should originally be included in the second group is not included in the second group (that is, The radio field intensity values for classifying the two groups are adjusted so that the probability of occurrence of an error of “contained in the first group” is smaller than the second threshold. The first threshold value and the second threshold value may be the same value or different values. The classification reference adjustment unit 840 may repeat the adjustment of the classification reference a plurality of times. Thereby, a classification standard can be calculated with high accuracy.

  FIG. 9 schematically shows an example of a method for adjusting classification criteria. In FIG. 9, the vertical axis indicates the received signal strength (RSSI: Received Signal Strength Indicator) of the probe request. The horizontal axis represents the normalized frequency (sometimes referred to as frequency). The solid line shows a normalized frequency distribution 910 generated using data when a probe request with an RSSI of −60 dB or less is observed for about 30 minutes or more at the access point 102. The dotted line shows a normalized frequency distribution 920 generated using data other than data when a probe request with an RSSI of −60 dB or less is observed for about 30 minutes or more at the access point 102.

  The frequency distribution 910 is considered to indicate the RSSI distribution of the probe request from the wireless terminal of the user who did not visit the store 12. The frequency distribution 920 is considered to indicate the RSSI distribution of the probe request from the wireless terminal of the user who has visited the store 12.

  The frequency distribution 910 and the frequency distribution 920 are created under the condition that the RSSI threshold value for classifying probe request data into two is −60 dB. However, referring to FIG. It is found that the possibility that the user has come to the store 12 is very small, and the condition that the RSSI threshold is −60 dB was a very strict condition.

  For example, when the user automatically detects that the user has entered the store 12 and issues a coupon ticket, it is preferable to use very strict conditions. However, when grasping the customer situation of the store 12, it can be seen that data more suitable for the actual situation can be obtained by adjusting the RSSI threshold value for classifying the probe request data into two to about -80 dB.

  As described above, the classification criterion adjustment unit 840 adjusts the classification criterion based on the probability distribution or the normalized frequency distribution of at least two groups of the plurality of groups, so that the classification criterion adjustment unit 840 can appropriately respond to the purpose of the data processing. Results. Since the terminal position determination module 634 includes the classification reference adjustment unit 840, the terminal position determination module 634 can more appropriately determine whether or not the wireless terminal exists within the range of the local area. As a result, the location providing server 120 can provide accurate terminal location information and terminal attribute information.
