Description

Communication system, information analysis apparatus, and information analysis method

The present invention relates to an information analysis apparatus and an information analysis method for estimating the number of population flows, and a communication system including the information analysis apparatus.

Conventionally, as a method of collecting data on macroscopic population flow, there has been a national census conducted nationwide in a five-year cycle, or a person trip survey that investigates the behavior history of the subject. These census or person trip surveys require a series of extremely time-consuming tasks such as distributing and collecting questionnaires to the target people and compiling them using many people. It took time. In addition, it was a burden for the respondents to complete and return the questionnaire.

JP 2005-202546 A

As described above, it has been very troublesome to collect data on macroscopic population flow in the past, and it has been difficult to collect such data easily and quickly to obtain survey results.

On the other hand, a technique for estimating the amount of movement of a person based on the number of passengers at a station is described in Patent Document 1, but even with this technique, the processing load for determining the number of passengers at a station, which is basic data for estimation And takes time. Therefore, there has been a long-awaited technique for collecting data on population flow that is simpler and quicker.

The present invention has been made in view of the above problems, and aims to collect data on macroscopic population flow easily and quickly.

In this specification, an area unit controlled by each base station is referred to as a “sector”. That is, handover occurs when moving between sectors, and at the time of such handover, a new connection (branch) is generated between the mobile station and the base station that controls the destination sector (ie, a branch is added). ).

The present applicant paid attention to a communication procedure in which the addition of a branch at the time of handover as described above is automatically reported from the mobile station to the radio network controller (RNC) without any special action by the mobile station user. . When reporting the addition of a branch, a message (hereinafter referred to as “branch addition report”) including the sector identification information of the movement source and the sector identification information of the movement destination relating to the added branch is transmitted from the mobile device to the radio network controller. Thus, the radio network controller can count the number of added branches for each combination of the move source sector identification information and the move destination sector identification information based on the received branch addition report. It becomes. Here, the applicant of the present invention is that the number of branch additions for each combination of the movement source sector identification information and the movement destination sector identification information obtained by this tabulation has moved from the movement source sector to the movement destination sector. In particular, the present invention relating to data collection related to macroscopic population flow based on the number of added branches has been achieved.

A communication system according to an aspect of the present invention includes a plurality of mobile devices located in sectors controlled by a plurality of base stations, a radio network controller that controls the plurality of base stations, and the radio network controller, Each of the mobile devices includes a sector identification information of a movement source and a sector of a movement destination according to a branch added at the time of handover. A transmission unit that transmits a branch addition report including identification information to the radio network control device, and the radio network control device is received with a reception unit that receives the branch addition report from each mobile device. Based on the branch addition report, the number of added branches is tabulated for each combination of source sector identification information and destination sector identification information. And an additional number information transmitting unit that transmits the additional number information of the branch for each combination of the movement source sector identification information and the movement destination sector identification information obtained to the aggregation to the information analysis device. The information analysis device includes an additional number information receiving unit that receives, from the wireless network control device, additional number information of the branch for each combination of the movement source sector identification information and the movement destination sector identification information; An estimation unit that estimates the added number information of the branch for each combination of the movement source sector identification information and the movement destination sector identification information as population flow number information from the movement source sector to the movement destination sector. And.

In this communication system, when the transmission unit of each mobile station transmits a branch addition report including the sector identification information of the movement source and the sector identification information of the movement destination related to the branch added at the time of handover, to the radio network control device, In the network control device, the receiving unit receives a branch addition report from each mobile device, and based on the received branch addition report, the totaling unit for each combination of the source sector identification information and the destination sector identification information. Aggregate the number of branches added. Then, when the additional number information transmission unit transmits the additional number information of the branch for each combination of the movement source sector identification information and the movement destination sector identification information obtained by the above aggregation to the information analysis device, the information analysis device The additional number information receiving unit receives the additional number information of the branch from the radio network controller, and the estimating unit adds the branch for each combination of the received source sector identification information and the destination sector identification information. The number information is estimated as population flow number information from the movement source sector to the movement destination sector. As described above, branch addition reports from each mobile device that are relatively easily obtained without requiring any special action by each mobile device user are obtained by being aggregated by the wireless network control device. Estimate the population flow number information from the source sector to the destination sector from the additional number information of the branch for each combination of the sector identification information and the destination sector identification information. It can be obtained quickly (in near real time).

The communication system may further include an associating unit that associates the movement source sector and the movement destination sector in the estimated population flow number information with the sector on the output map. The original sector and the destination sector can be associated with a sector on the map.

In addition, the communication system further includes an output unit that outputs the population flow number information from the movement source sector to the movement destination sector in the map by a predetermined notation based on a result of the association. In this case, the output unit outputs the population flow number information from the movement source sector to the movement destination sector in the map by a predetermined notation based on the result of the association. As described above, by outputting the population flow number information from the movement source sector to the movement destination sector in the map, it is possible to easily grasp data regarding macroscopic population flow. Needless to say, “output” here includes display output and print output.

Note that the aggregation processing in the wireless network control device can be performed at arbitrary timing and at arbitrary time intervals. For example, by performing the counting process at intervals of 2 hours, it is possible to obtain population flow number information for each unit time zone by setting 2 hours as one unit time zone. In this way, it is possible to obtain population flow number information for each desired unit time zone.

Moreover, in the conventional national census and person trip survey, there is a concern that the accuracy of the survey results may decrease due to a decrease in the collection rate of the basic questionnaire. In the present invention, no special action is required by each mobile device user. Since a branch addition report is obtained from each base mobile device, it is possible to avoid a decrease in the accuracy of the analysis result due to insufficient basic data.

[Functional block configuration of communication system]
Next, a functional block configuration of the communication system according to the present embodiment will be described. FIG. 2 shows a functional block configuration of the communication system 10. As shown in FIG. 2, the communication system 10 includes, as elements according to the present invention, a plurality of mobile devices 100 located in sectors controlled by a plurality of BTSs (base stations) 200, an RNC 300, and an information analysis device. 600. The information analysis apparatus 600 corresponds to the mobile demography unit 503 and the visualization solution unit 504 of FIG. Since the exchange 400, the social sensor unit 501 and the petamining unit 502 in FIG. 1 are devices not directly related to the present invention, these notations are omitted in FIG.

The mobile device 100 includes a transmission unit 101 that transmits a branch addition report related to the branch added at the time of handover to the RNC 300. The “branch addition report” here includes source sector identification information (hereinafter referred to as “movement source sector ID”) and destination sector identification information (hereinafter referred to as “movement destination sector ID”). According to the standard specification “Radio Resource Control (RRC) Protocol Specification: 3GPP TS 25.331”, it is stipulated that an “ACTIVE SET UPDATE COMPLETE” message is transmitted from the mobile device 100 to the RNC 300 when a branch is added. This message corresponds to the above branch addition report.

The RNC 300 receives the branch addition report from the mobile device 100, and tabulates the number of branch additions for each combination of the movement source sector ID and the movement destination sector ID based on the received branch addition report. Information on the number of branches added for each combination of the migration source sector ID and the migration destination sector ID (hereinafter referred to as “branch addition number information”), which is obtained by aggregation, is transmitted to the information analysis apparatus 600. A transmission unit 303.

For example, as shown in FIG. 4, the branch addition number information includes a source sector ID (indicated as “From sector ID” in FIG. 4), a destination sector ID (indicated as “To sector ID” in FIG. 4), and It is expressed in a table format that associates the number of branch additions. In addition, the aggregation process by the aggregation unit 302 can be performed at arbitrary timing and at arbitrary time intervals. Here, as an example, the total processing execution time is set to 1 hour intervals such as 10:00, 11:00, 12:00, 13:00, and so on.

The information analysis apparatus 600 includes an additional number information receiving unit 601 that receives from the RNC 300 branch addition number information for each combination of a movement source sector ID and a movement destination sector ID, and a combination of the received movement source sector ID and movement destination sector ID. An estimation unit 602 that estimates information on the number of added branches for each branch as population flow number information from the migration source sector to the migration destination sector, and a migration source sector and a migration destination sector in the estimated population flow number information Is associated with the sector on the map to be output, and the population flow from the source sector to the destination sector on the map by a predetermined notation (an arrow notation as an example) based on the result of the association An output unit 604 for outputting numerical information. Needless to say, “output” here includes display output and print output widely. That is, the population flow number information may be displayed and output on a display or the like, may be printed out from a printer or the like, or may be output both in display and printing.

[Processes executed in the communication system]
Next, a series of processes executed in the communication system 10 will be described with reference to FIG.

When the mobile device 100 detects the addition of a branch during the handover of the mobile device 100, the transmission unit 101 of the mobile device 100 reports a branch addition related to the added branch (including the source sector ID and the destination sector ID). Information) is transmitted to the RNC 300 (step S1 in FIG. 3). This operation is performed in each of a large number of mobile devices 100. As a result, a large number of branch addition reports reach the RNC 300 via the BTS 200.

In the RNC 300, the receiving unit 301 receives a number of branch addition reports (step S2), and the totaling unit 302 reads the source sector ID and destination sector ID for each received branch addition report, The number of branch additions is tabulated for each combination of destination sector IDs (step S3). As a result, the information in the table format shown in FIG. 4 in which the source sector ID (From sector ID), the destination sector ID (To sector ID), and the number of branch additions are associated with each other is obtained. Then, the additional number information transmission unit 303 transmits branch addition number information for each combination of the movement source sector ID and the movement destination sector ID obtained by the aggregation to the information analysis apparatus 600 (step S4). The transmission in step S4 may be executed periodically at a predetermined time interval, may be executed at a preset time, or may be executed using a transmission request from the information analysis apparatus 600 as a trigger. Good.

In the information analysis apparatus 600, when the additional number information receiving unit 601 receives the branch additional number information from the RNC 300 (step S5), the estimating unit 602 uses the branch additional number information (combination of the movement source sector ID and the movement destination sector ID). The information on the number of added branches for each branch) is estimated as the population flow number information from the transfer source sector to the transfer destination sector (step S6). For example, by estimating the branch addition number information shown in FIG. 4 as the population flow number information, the branch addition number corresponding to the combination of the movement source sector ID “1” and the movement destination sector ID “2” is “10”. The population flow number from the migration source sector ID “1” to the migration destination sector ID “2” is estimated to be 10.

Then, the associating unit 603 associates the movement source sector and the movement destination sector in the estimated population flow number information with the sector on the output map (step S7), and the output unit 604 associates Based on the result, the population flow number information from the movement source sector to the movement destination sector in the map is output by a predetermined notation (an arrow notation as an example) (step S8). For example, when sectors 1 to 5 on the output map are sectors 1 to 5 as shown in FIG. 5A, the number of population flows from the source sector ID “1” to the destination sector ID “2” As for the population flow rate information of 10 people, the source sector ID “1” and the destination sector ID “2” are respectively associated with the

sectors

1 and 2 on the map, and as a result, from sector 1 to sector 2 An arrow is written as shown in FIG. 5B, and “10” indicating the number of population flows is written in the vicinity of the arrow. Similarly, for the population flow number information that the number of population flows from the migration source sector ID “1” to the migration destination sector ID “3” is 5, the migration source sector ID “1” and the migration destination sector ID “3” are the same. Each is associated with

sectors

1 and 3 on the map. As a result, an arrow from sector 1 to sector 3 is represented as shown in FIG. 5B, and “5” indicating the number of population flows is in the vicinity of the arrow. It is written.

Note that the population flow number information is not limited to being output by combining the arrow and the population flow number as shown in FIG. 5B, but is moved according to the direction of the arrow as shown in FIG. 5C. While representing the sector ID and the destination sector ID, the population flow number may be represented by the thickness of the arrow. In addition, the type of the arrow color may be changed according to the population flow rate, or the arrow color density may be changed according to the population flow rate. Moreover, the arrow notation is not essential, and it is also possible to output the difference in the population flow by color coding of the sectors.

According to the present embodiment as described above, from the branch addition number information for each combination of the movement source sector ID and the movement destination sector ID obtained based on the branch addition report from the mobile device relatively easily obtained, It is possible to estimate the population flow number information from the migration source sector to the migration destination sector, and to obtain data on macroscopic population flow quickly (in near real time). Further, by outputting population flow number information from the source sector to the destination sector as shown in FIGS. 5B and 5C, it is possible to easily grasp data regarding macroscopic population flow visually. it can.

In addition, since the execution time of the aggregation processing by RNC is set to 1 hour intervals such as 10:00, 11:00, 12:00, 13:00, ..., 1 hour is taken as one unit time zone. Population flow number information for each unit time zone can be obtained. Of course, since the execution time and time interval of the counting process can be set arbitrarily, it is possible to obtain population flow number information for each desired unit time zone.

Also, in the conventional census and person trip surveys, there is a concern that the accuracy of the survey results may decrease due to a decrease in the collection rate of the basic questionnaire. In this embodiment, no special action is required by each mobile device user. In addition, since a branch addition report is obtained from each base mobile device, it is possible to avoid a reduction in accuracy of the analysis result due to insufficient basic data.
