FIG. 1 shows a configuration example of an area analysis system of the present invention.
In FIG. 1, wireless LAN base stations AP1 and AP2 connected to a network are installed in a station or a store and provide a public wireless LAN service. The wireless LAN base station may be installed at home. The mobile phone base station BS is also connected to the network, and covers a wider area than a public wireless LAN with one base station. The user possesses the wireless router 10 and the wireless LAN terminal 20, and moves in a wireless LAN area in which communication with the wireless LAN base stations AP1 and AP2 and a mobile phone area in which communication with the mobile phone base station BS is possible. The area analysis server 100 connected to the network has a function of collecting line selection information of WAN-side lines in the wireless router 10 and analyzing the usage status for each line type.

FIG. 2 shows a configuration example of the wireless router 10.
In FIG. 2, the WAN side wireless LAN transmission / reception unit 11, the WAN side mobile phone transmission / reception unit 12, the LAN side wireless LAN transmission / reception unit 13, and the control unit 14 for switching the connection of the WAN side line are connected to the conventional wireless router 10 shown in FIG. Has the same function.

  The wireless router 10 of the present embodiment receives a GPS signal from a GPS (Global Positioning System) satellite at regular intervals (for example, 1 second) as means for acquiring position information of the current position, and receives the latitude and longitude of the reception point. The GPS signal receiving unit 15 for calculating the position information and the position information storage unit 16 for storing the time information and the position information are provided. When position information cannot be calculated, such as when a GPS signal cannot be received, the last received latitude and longitude information is retained.

  The control unit 14 registers, in the communication status storage unit 17, the WAN side line being used at regular intervals and the communication data amount transmitted and received on the WAN side line measured by the communication data amount counter 18. Here, the period registered in the communication status storage unit 17 is defined as a registration period. An example of a communication status list registered in the communication status storage unit 17 is shown in FIG. Here, the registration cycle is 10 seconds. Information stored in the position information storage unit 16 is used for time, latitude, and longitude. For the WAN side use line, the line used at the time of registration is stored, and the amount of communication data transmitted / received using the WAN side line for 10 seconds is stored. If the WAN side use line is switched during the registration period, that fact is registered.

  The communication status registered in the communication status storage unit 17 of the wireless router 10 is transmitted at regular intervals to the area analysis server 100 connected to the network as a communication status list. For example, the data is transmitted once a day in a time zone with a small amount of data in the network such as a midnight time zone. Transmission uses one of the WAN side lines, but when there is a lot of data to be transmitted, the transmission in a short time is completed by using the wireless LAN line as much as possible. When transmitting to the area analysis server 100 by mail, the wireless router 10 may be provided with a mail transmission function.

FIG. 4 shows a configuration example of the area analysis server 100.
In FIG. 4, the area analysis server 100 is connected to the network, receives the communication status list sent from each wireless router 10 by the communication unit 101, and registers it in the communication status list storage unit 102. The communication status list storage unit 102 has a large capacity because the communication status list is sent from each wireless router 10 at a constant cycle. The area analysis processing unit 103 reads the communication status list, creates a partition information list for analyzing the communication status for each line type, and stores it in the partition information list storage unit 104. Moreover, you may provide the display part which displays a division information list.

  Next, an operation example of the area analysis processing unit 103 will be described. The area analysis processing unit 103 creates a section information list for each line type to be analyzed. FIG. 5 shows the concept of the section of the section information list, and FIG. 6 shows an example of the section information list that is actually processed in the area analysis processing unit 103.

  The section information list includes items of coordinates of the section (for example, (A, 1)), latitude / longitude indicating the position of the coordinates, and total communication data amount storing the total amount of communication data received from each wireless router. . Here, A, B, C,... Indicating the coordinates of the sections indicate latitude directions, 1, 2, 3,... Indicate longitude directions. The size of the section can be set according to the accuracy to be analyzed, such as a latitude / longitude unit or 50 m square. Here, a numerical value of four digits after the decimal point of latitude and longitude is used.

  Hereinafter, an example of creating a partition information list indicating the total communication data amount of each partition for two types of cellular phones and wireless LANs as WAN side lines will be described. For example, a section information list (mobile phone) and a section information list (wireless LAN) are used. For example, when a cell phone section information list is required, only the section information list (cell phone) is created.

  The area analysis processing unit 103 acquires one communication status list from the communication status list storage unit 102 and adds the communication data amount to the total communication data amount of the partition information list for each row in the communication status list according to the following procedure. Go. First, the cellular phone and the wireless LAN are identified by the item of the WAN side use line, and it is determined whether to add the communication data amount of the row to the partition information list (mobile phone) or the partition information list (wireless LAN). The corresponding section in the section information list is searched from the latitude and longitude of the line. Then, the amount of communication data of the section is added. For example, if the WAN side use line is a mobile phone and the latitude and longitude correspond to the section (A, 3), the communication data amount of that row is the section (A, 3) of the section information list (mobile phone). It is added to the total communication data amount. The amount of communication data in each row in the communication status list is sequentially added to each section of the section information list (mobile phone) and the section information list (wireless LAN). Since a large number of communication status lists are stored in the communication status list storage unit 102, the same processing is sequentially performed for each list, and the communication data amount is added to the partition information list. Calculation of the amount of communication data in each section in the section information list is completed by adding the amount of communication data for all communication status lists. As a display method to the operator, the total communication data amount of the block information list is mapped on the map, and the magnitude of the numerical value is identified and displayed by color shading and symbols, so that the communication status map is communicated at a glance. An operator can recognize a place with a large amount of data.

  From this section information list, points where the communication data amount of the corresponding WAN side line is large can be known, and it is possible to consider measures such as enhancement of communication facilities. After that, since the communication status list is sequentially sent from each wireless router 10, the accuracy can be improved by reflecting the contents in the section information list.

  As a method for transmitting the communication status list from the wireless router 10 to the area analysis server 100, FTP or HTTP can be used. In that case, the wireless router 10 is provided with those protocols. Transmission to the area analysis server 100 can be performed periodically such as once a day, but can also be performed when the capacity of the communication status storage unit 17 exceeds a certain amount. .

  In addition, it is possible to perform area analysis for each cellular phone operator, and for a wireless LAN, it is also possible to perform area analysis for each public wireless LAN operator. This can be dealt with by storing the identifier of the communication carrier as an item of the WAN side use line stored in the communication status storage unit 17 of the wireless router 10. For identification of the communication carrier, information of a SIM card mounted on a router can be used for a mobile phone line, and ESS-ID can be used for a wireless LAN.

  In the second embodiment, an area analysis system that creates a partition information list by distinguishing not only the type of WAN side line selected by the wireless router 10 but also the type of moving means of the user will be described. To identify the moving means, the user's moving speed is referred to, and a section information list for each moving speed is created. A threshold of the moving speed for dividing the section information list is set in advance.

  In the following, when the WAN side use line is a mobile phone and a wireless LAN, it is assumed that it is distinguished whether the train is on the railroad or walking, and the moving speed is greater than or equal to the threshold value and less than the threshold value The section information list is created separately. In addition, the moving speed threshold is 20 km / h. The section information list is classified into the following four types based on the WAN side use line and the moving speed. Here, a section information list (mobile phone: high speed), a section information list (mobile phone: low speed), a section information list (wireless LAN: high speed), and a section information list (wireless LAN: low speed) are used. The section information list shown in FIG. 6 can be used.

  The communication status list sent from the wireless router 10 to the area analysis server 100 is the same as in the first embodiment. The sent communication status list is stored in the communication status list storage unit 102 of the area analysis server 100.

  The area analysis processing unit 103 calculates a moving speed in each row of the list from the received communication status list, and selects a partition information list to which the communication data amount is added from four types of partition information lists. The selection procedure is shown in FIG.

  First, the area analysis processing unit 103 acquires one communication status list from the communication status list storage unit 102 (S1), and calculates the moving speed of each row (S2). In the communication status list shown in FIG. 3, the position for each registration cycle is recorded, and the moving speed of a certain row is calculated by “moving speed = (positional difference) ÷ from the time and position difference of the previous point. (Time difference) ”. For example, if the time interval is 30 seconds, the previous position is 35.3236 degrees north latitude, 139.5548 degrees east longitude, 35.3240 degrees north latitude, 139.5552 degrees east longitude, the travel distance is about 40m, 40m ÷ 30 seconds = speed per minute It is determined to be 80m, and the speed is 4.8km / h.

  Next, it is compared whether or not the calculated moving speed is equal to or higher than a preset threshold (S3). Since the moving speed in the above example is less than the threshold speed of 20 km / h, the moving speed becomes “low speed”, and the section information list to be selected depends on the WAN side use line (S4), and the section information list (mobile phone: low speed) Or it becomes a section information list (wireless LAN: low speed) (S5, S6). On the other hand, if the moving speed is equal to or higher than the threshold, the moving speed is “high speed”, and the section information list to be selected is a section information list (mobile phone: high speed) or section information list (wireless) depending on the WAN side use line (S7). LAN: high speed) (S8, S9).

  When each section information list is selected, the corresponding section in the section information list is searched from the latitude and longitude of the line of the communication status list. Then, the amount of communication data of the section is added. The amount of communication data in each row in the communication status list is added to each partition in the selected partition information list. Since the communication status list for each wireless router is stored in the communication status list storage unit 102, the same processing is sequentially performed for each list, and the communication data amount is added to the partition information list. By adding the communication data amount for all the communication status lists, the calculation of the communication data amount in each area in the partition information list is completed.
