1 is a diagram schematically illustrating a configuration of a location information management system in a mobile communication network according to an embodiment of the present invention.

First, mobile communication service subscribers use various mobile communication services such as voice call service, SMS service, wireless Internet service, etc. using their own mobile communication terminals 10-1, 10-2, ..., 10-n. In this case, an exchange for relaying a voice call, a Short Message Service Center (SMSC) 50 for relaying an SMS service, a data service node (eg, SGSN, GGSN, etc.) for relaying a wireless Internet service may be used. In order to perform the charging according to the charge data (CDR) is generated.

That is, when the mobile communication service subscriber uses the voice call service using the mobile communication terminals 10-1, 10-2, ..., 10-n, the exchange relaying the voice call performs charging according to the voice call. To generate the charge data for the voice call, the generated charge data is the calling terminal identification number of the calling terminal identification information, the called terminal terminal number of the called terminal identification information, the call start and end time, the base station to which the calling terminal is connected And the identification number of the exchange, the base station to which the destination terminal is connected, and the identification number of the exchange.

When the mobile communication service subscriber uses the SMS service using the mobile communication terminals 10-1, 10-2,..., 10-n, the SMSC 50 relaying the SMS service transmits the SMS message. The billing data is generated to perform billing, and the generated billing data includes the calling terminal telephone number, called terminal telephone number, message sending time, identification number of the base station and exchange to which the calling terminal is connected, and the base station to which the called terminal is connected. And the identification number of the exchange.

If the mobile communication service subscriber uses the wireless Internet service using the mobile communication terminals 10-1, 10-2, ..., 10-n, the data service node relaying the wireless Internet service is connected to the wireless Internet connection. Generate billing data to perform the billing according to the generated billing data, the generated billing data is the identification number of the mobile communication terminal (10-1, 10-2, ..., 10-n) using the wireless Internet service, the terminal using the wireless Internet service IP address and port number, access point name (APN), date and time when starting to receive wireless Internet service, number of uplink bytes transmitted and number of downlink bytes transmitted, mobile communication terminal 10 -1, 10-2, ..., 10-n) include identification numbers of the base station and the data service node connected to receive the wireless Internet service.

As described above, the billing data includes a base station to which each mobile communication terminal 10-1, 10-2, ..., 10-n is connected to receive a mobile communication service such as voice call, SMS, wireless Internet, and the like. It includes the identification number of the exchange (or data service node).

Accordingly, the billing data collection server 20 generates at the exchange, the SMSC 50, the data service node, etc. as the mobile communication terminals 10-1, 10-2, ..., 10-n use mobile communication services. Of the base station and the exchange (or data service node) to which the mobile communication terminals 10-1, 10-2,..., 10-n are connected to receive the billing data and to receive a mobile communication service from the received billing data. After extracting the identification information to determine the administrative area of the service area that the base station has jurisdiction (in the embodiment of the present invention, the administrative area can be managed by the town, town, town) ID, and then the mobile communication terminal using the mobile communication service ( 10-1, 10-2, ..., 10-n) location information is managed using the administrative district ID.

In more detail, the billing data collection server 20 receives the billing data generated by the exchange, the SMSC 50, the data service node, and the like, and then transfers the billing data to each mobile communication terminal 10-1. 10-2, ..., 10-n) extracts identification numbers of the base station and the exchange (or data service node) connected to receive the service, and then the base station information mapping table for each administrative region as shown in FIG. With reference to the identification number of the extracted base station and the exchange (or data service node) to determine the administrative area ID of the service area that the base station has jurisdiction.

As shown in FIG. 2, the base station information mapping table for each administrative area includes identification information of each base station, identification information of an exchange to which each base station belongs, an administrative area address of an area where each base station is located, and an area where each base station is located. It includes a postal code, a district ID of the area where each base station is located, and the like.

Here, since the billing data collection server 20 cannot determine the service area which the base station has jurisdiction with only the identification number of the base station, the billing data collection server 20 extracts not only the base station identification number but also the exchange (or data service node) identification number.

As shown in Fig. 2, the billing data collection server 20 maps and manages the postal code related to the service area managed by each base station by mapping the administrative area ID to the mobile communication terminals 10-1, 10-2, ..., 10-n) location information can be managed based on the administrative area address that is easy for the general public.

Meanwhile, as new networks are introduced due to the development of mobile communication technologies, various types of mobile communication networks such as CDMA 2000, Wireless Broadband Internet (WIBRO), and Wideband CDMA (WCDMA) are used as overlays, and thus, different types are used in the same region. The base station for providing a mobile communication service of the will be installed.

Accordingly, even if the identification numbers of the base station and the exchange extracted from the charging data have different values from the identification numbers of the base station and the exchange extracted from the other charging data, the identified administrative area ID may be the same.

As described above, using the identification numbers of the base station and the exchange extracted from the billing data, the billing data collection which grasps the administrative area ID of the area where the mobile communication terminals 10-1, 10-2, ..., 10-n are currently located. The server 20 manages the location information for the mobile communication terminals 10-1, 10-2, ..., 10-n, whose location is determined by the administrative area ID, for each administrative area ID as shown in FIG. Update to the mobile terminal location information table.

The mobile communication terminal location information table managed for each administrative area ID includes identification information (examples) of the mobile communication terminals 10-1, 10-2, ..., 10-n having the corresponding administrative area ID as location information for each administrative area ID. For example, MDN), the time when the location information was updated, the location registration source (billing data generated by using voice call service, billing data generated by using SMS service, billing data generated by using wireless Internet service, etc.) And a remark value indicating whether the subscriber is gender or age, voice call or SMS message sent, incoming call, or wireless Internet use.

As described above, the billing data collection server 20 manages the location information of the mobile communication terminal for each administrative area ID. The mobile communication terminal 10-1, which is located in the first administrative area and receives the mobile communication service, When the mobile communication service is provided by moving to the second administrative area, the location information of the mobile communication terminal 10-1 is updated in the mobile communication terminal location information table of the second administrative area, and the mobile communication terminal of the first administrative area. It is deleted from the location information table.

As described above, the billing data collection server 20 can secure information on the gender and age of the subscriber from a subscriber information management server (not shown) managed separately by each service provider.

Meanwhile, the location information management and reasoning server 30 receives the updated information from the billing data collection server 20 whenever an update occurs in the billing data collection server 20, and receives the billing data collection server 20 from the updated information. The location information table of the mobile communication terminal managed for each subscriber is updated using the update information.

In the above-described location information table of the mobile communication terminal managed for each subscriber, location information obtained by using the charging data generated as each mobile communication terminal uses the mobile communication service is sequentially recorded.

Accordingly, the location information management and reasoning server 30 is based on the past location information of each of the mobile communication terminals 10-1, 10-2,. It is possible to infer a list of subscribers that are supposed to be located.

In addition, the location information management and inference server 30 may provide a mobile communication service from a location information management server (not shown) that manages subscriber location information for each service provider to secure location information of subscribers who do not frequently use the mobile communication service. Location information of infrequently used subscribers can be obtained.

On the other hand, the location-based service providing server 40, if there is information to provide to subscribers that are estimated to be located in a particular region on a particular day, a specific time zone, location information management and reasoning server 30 to a specific day and time zone Requests a list of subscribers estimated to be located in a specific area at, and transmits information to be provided to all mobile communication terminals belonging to a subscriber list provided from the location information management and inference server 30.

4 is a flowchart illustrating a method of managing location information in a mobile communication network according to an embodiment of the present invention.

First, the mobile communication terminal 10-1, 10-2, ..., 10-n performs a voice call with the called terminal, sends an SMS message to the called terminal, or accesses the wireless Internet to provide the wireless Internet service. When the exchange relays the voice call, the SMSC 50 relaying the SMS service, the data service node relaying the wireless Internet service (eg, SGSN, GGSN, etc.), the charging data is generated to perform the charging. The billing data collection server 20 exchanges the billing data generated by the mobile communication terminals 10-1, 10-2,..., 10-n using the mobile communication service, the SMSC 50, and the data. It receives from a service node (eg, SGSN, GGSN, etc.) (S10).

The billing data collection server 20 that has received billing data from the exchange, the SMSC 50, the data service node, and the like through the process S10 described above, is the base station to which the outgoing telephone number and the calling terminal are connected to receive the service from the billing data. And the identification number of the exchange, the called telephone number, and the identification numbers of the base station and the exchange to which the called terminal is connected to receive the service (S12).

If the billing data received at step S10 is billing data received at the data service node according to the use of the wireless Internet service, the calling telephone number and the base station to which the calling terminal is connected to receive the service at step S12. And an identification number of the data service node.

Thereafter, in the base station information mapping table for each administrative area, using the identification numbers of the base station and the exchange (or data service node) extracted in step S12, the administrative area of the service area managed by the base station to which the calling terminal and the called terminal are respectively connected. The ID is determined (S14).

The administrative district ID of the service area managed by the calling base station and the called base station respectively identified through the process S14 becomes the administrative area ID of the area where the calling terminal and the called terminal are located, respectively. This is because a mobile communication terminal connected to a base station and receiving a mobile communication service is located within a predetermined radius from the base station. Thus, if the location information of the base station is known, the mobile communication terminals 10-1, 10-2, ..., 10-n are located. The location information of can also be known.

The billing data collection server 20 which grasps the location information of the calling terminal and the called terminal by using the identification numbers of the base station and the exchange extracted from the billing data through steps S12 and S14 described above is a mobile communication in which the location is identified by the administrative area ID. The location information of the terminals 10-1, 10-2, ..., 10-n is updated in the mobile communication terminal location information table managed for each administrative area ID (S16).

Subsequently, the charging data collection server 20 transmits the updated information to the location information management and inference server 30 as the mobile communication terminal location information table managed for each administrative area ID is updated (S18) and collects the charging data. The location information management and inference server 30 that has received the updated information from the server 20 uses the update information received from the billing data collection server 20 through the process S18 of the mobile communication terminal managed for each subscriber. The location information table is updated (S20).

In the above-described location information table of the mobile communication terminal managed for each subscriber, location information obtained by using the charging data generated as each mobile communication terminal uses the mobile communication service is sequentially recorded.

On the other hand, when the location-based service providing server 40 generates information to be provided to subscribers that are estimated to be located in a specific region on a specific day of the week, a specific time zone, the location-based service providing server 40 is location information management and inference The server 30 requests a list of subscribers estimated to be located in a specific region at a specific day of the week and a specific time zone (S22).

The location information management and reasoning server 30, which has received a list of subscribers estimated to be located at a specific day of the week, at a specific time zone, from the location-based service providing server 40 through the above-described process S22, is managed by the subscriber. Based on the past location information of each of the mobile communication terminals 10-1, 10-2, ..., 10-n stored in the location information table of the communication terminal, it may be located in a specific region on a specific day of the week and a specific time zone. Inferred subscribers are estimated (S24), and provides the inferred subscriber list to the location-based service providing server 40 (S26).

The location-based service providing server 40, which has received the subscriber list from the location information management and inference server 30 through the process S26, all movements belonging to the subscriber list provided from the location information management and inference server 30. Information to be provided to the communication terminal is transmitted (S28).
