Hereinafter, a location information collecting method and a server according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, terms used in the present invention are summarized as follows.

The terminal identification information is an International Mobile Station Identity (IMSI) and a Temporary Mobile Subscriber Identity (TMSI).

The IMSI is stored in the subscriber identity module (SIM) as a unique identifier that requests each user when a mobile communication network operator registers a user for a service.

The TMSI is a value assigned by the exchange or Visitor Location Register (VLR) to prevent the IMSI from being exposed in the radio section. When the terminal performs the exchange period handover and is registered in another exchange, a new TMSI is allocated Receive.

The location information of the terminal (user) is a location area code (LAC) and a service area code (SAC) or a cell identity (CI).

1 is a diagram schematically illustrating a configuration of a mobile communication system for collecting location information through a RANAP message according to an embodiment of the present invention.

1, a user equipment (UE) 10 is subscribed to a mobile communication service and receives a call (voice) from a base station 15 through a reverse link and a forward link, / Character / packet) or makes a call to the base station 15.

The terminal 10 may be implemented as a terminal capable of receiving a mobile communication service through a CS (Circuit Switching) network such as a mobile communication terminal or a smart phone.

A base station (Node B) 15 is connected to a corresponding base station controller 20 and plays a role of relaying between the base station controller 20 and a terminal 10 located in a cell area occupied by the base station controller 15 itself.

A base station controller (RNC) 20 performs resource allocation, call control, handoff control, voice and packet processing, etc. to the base station 15 connected thereto, (Base station, cell) information used as location information of the terminals 10 connected to the base station.

Mobile switching centers (MSC) 25 and 35 are devices for providing a circuit switching service to a mobile communication subscriber in cooperation with a circuit network, and manage base station controllers 20 connected thereto.

The above exchanges 25 and 35 are connected to the base station controller 20 in order to support the mobile communication service by using the RANAP message and to transmit the mobility such as Location Update, Location Registration, Management (MM: Mobility Management).

When the terminal 10 performs a location registration and location update or when a call origination / incoming call or an SMS origination / reception is made, the exchanges 25 and 35 send a home location register (HLR) 10) of the mobile communication terminal. At this time, the location information of the terminal 10 registered or updated in the home location register 40 is not the base station information managing the area where the terminal 10 is located, but the exchange information is the location information of the terminal 10.

Upon call set-up, the originating exchange 35 queries the home location register 40 for the location of the destination exchange and forwards the RANAP message to the destination exchange 25 according to the result. The destination exchange 25 receiving the RANAP message transmits the RANAP message to the base station controller 20 to which the terminal 10 belongs and the base station controller 20 transmits the RANAP message back to the base station 15, And transmits a call set-up signaling message to the called terminal.

The router 30 mirrors all RANAP messages exchanged between the base station controller 20 and the switch 25 for the incoming / outgoing call processing and location registration processing of the terminal 10, To the message collecting unit (53) of the terminal (50).

All the RANAP messages exchanged between the base station controller 20 and the switch 25 in the router 30 are mirrored using the port mirroring function of the router 30 and the mirrored RANAP message is transmitted as a message (TAP) is placed on the connection line between the base station controller 20 and the switchboard, and then, all of the tabs (TAP) placed between the base station controller 20 and the switchboard 25 (E.g., an optical distributor) to the connection line between the base station controller 20 and the exchange 25, or to transmit the RANAP message to the message collecting unit 53 All the RANAP messages exchanged between the base station controller 20 and the exchanges 25 and 35 through the signal distributor may be distributed to the message collecting unit 53 and transmitted.

The location information collection server 50 collects all RANAP messages exchanged between the base station controller 20 and the exchange 25 and analyzes the collected RANAP messages to extract only the messages used for location information of the terminal 10 And collects the location information of the terminal 10 from the extracted message and includes a message collecting unit 53, a location information extracting unit 55 and an identification information DB 57.

When receiving the RANAP message from the router 30 (or any one of the tap and the signal distributor), the message collecting unit 53 analyzes the received RANAP message and extracts only the message used for checking the location information of the terminal 10 , And transmits the extracted message to the location information extracting unit 55.

The message collecting unit 53 analyzes an RANAP message received from the router 30 (or any one of the tap and the signal distributor) to generate an initial UE message for a Location Updating Request, An initial UE message for a CM service request, an initial UE message for a paging response, a direct transmission message for a Location Updating Accept, Direct transfer message, and paging request message, and transmits the extracted paging request message to the location information extracting unit 55.

Here, the message collecting unit 53 identifies the message structure and the parameter information defined in the protocol to distinguish the message. The initial UE message uses the message type included in the NAS (Non Access Stratum) payload of the initial UE message Whether the initial UE message is an initial UE message for a location update request, an initial UE message for a CM service request, or an initial UE message for a paging response.

The identification information DB 57 stores terminal identification information (IMSI, TMSI), telephone number (MSISDN), location information (LAC, SAC (or CI), and the like) for each terminal 10 under the control of the location information extracting unit 55. [ ). And location-based service information provided at a location corresponding to each location information (LAC, SAC (or CI)).

The location information extraction unit 55 extracts terminal identification information (IMSI, TMSI) and location information (LAC, SAC (or CI)) from the message received from the message collection unit 53 and then extracts the extracted terminal identification information (MSISDN) of the terminal from the identification information DB 57 using the extracted MSID and the extracted location information (LAC, SAC (or CI), and TMSI) ) To the location information DB (61) of the location-based service providing server (60) and stores the mapped location information.

When the paging request message is received from the message collecting unit 53, the location information extracting unit 55 extracts the terminal identification information (IMSI, TMSI) and the location information (LAC) from the paging request message. If the IMSI and the TMSI are both included, the IMSI and the TMSI are mapped to the identification information DB 57. If the IMSI is not included in the paging request message, And stores the telephone number (MSISDN) in the identification information DB 57 using the IMSI. If only the IMSI is included, the MSISDN is obtained from the identification information DB 57 using the IMSI without updating the identification information DB 57. At this time, if there is no telephone number (MSISDN) in the identification information DB 57, a request for telephone number (MSISDN) inquiry is made to the location information DB 61 of the location-based service providing server 60 using IMSI, And acquires the telephone number (MSISDN) from the information DB 61. Here, the location information DB 61 collects and manages IMSI and telephone number (MSISDN) mapping information periodically in cooperation with the customer information server of the mobile communication company, and manages the telephone number (MSISDN (MSISDN) for the IMSI in real time, and sends a response to the location information extracting unit 55. The location information extracting unit 55 extracts the location information of the IMSI from the IMSI.

As described above, the location information extracting unit 55, which has acquired the telephone number (MSISDN) using the terminal identification information (IMSI), extracts the location information of the terminal (MSISDN) LAC) and stores them in the location information DB 61. [ Then, the location information extracting unit 55 maps the acquired telephone number (MSISDN) of the terminal and the location information (LAC) and stores the same in the identification information DB 57.

On the other hand, when the location information extracting unit 55 receives any of the initial UE message for the location update request, the initial UE message for the CM service request, and the initial UE message for the paging response from the message collecting unit 53, The terminal identification information (IMSI, TMSI) and location information (LAC, SAC) are extracted from the received message. If the extracted TMSI is included in the TMSI, the IMSI is also retrieved from the identification information DB 57 using the TMSI, and the identification information DB (IMSI) is retrieved using the retrieved IMSI. 57). ≪ / RTI > If the extracted terminal identification information includes an IMSI in addition to the TMSI, a telephone number (MSISDN) is obtained from the identification information DB 57 using the IMSI. At this time, if there is no telephone number (MSISDN) in the identification information DB 57, the telephone number (MSISDN) inquiry is requested to the location information DB 61 using the IMSI, MSISDN). If the message received from the message collecting unit 53 is an initial UE message for a location update request, the location information extracting unit 55 extracts an exchange point code (LU_PC) included in the extracted location information (LAC, SAC) And maps the TMSI and the IMSI to the identification information DB 57 based on the exchange serial number (SEQ). When the location information extracting unit 55 receives a direct transmission message for accepting location update from the message collecting unit 53 in the future, it confirms that the two messages are in the same continuity. If the TMSI value is changed, So that it can be checked and updated.

As described above, the location information extracting unit 55, which has acquired the telephone number (MSISDN) using the terminal identification information (TMSI, IMSI), extracts the telephone number (MSISDN) of the acquired terminal, Information (LAC, SAC), and stores it in the location information DB 61. Then, the acquired telephone number (MSISDN) of the terminal and the location information (LAC, SAC) are mapped and stored in the identification information DB 57.

The position information extracting unit 55 extracts the initial UE message for the location update request, the initial UE message for the CM service request, or the terminal identification information extracted from the initial UE message for the paging response, The IMSI is obtained by inquiring of the identification information DB 57 with the TMSI, and there is no case where the corresponding IMSI is present in the identification information DB 57. [ In this case, the location information extracting unit 55 stores the TMSI and the extracted location information (LAC, SAC) in the identification information DB 57. For example, if the terminal 10 enters an exchange area of a local branch office and sends an initial UE message for location update request to the exchange 25 for location registration, but has not received an incoming call or incoming SMS yet, May not be stored in the identification information DB 57. In this case, the location information extracting unit 55 stores the location information (LAC, SAC) for the TMSI in the identification information DB 57 and acquires the IMSI for the TMSI in the future, (MSISDN), and updates the location information in the location information DB 61 using the telephone number (MSISDN). At this time, the TMSI-based location information can be received several times before acquiring the IMSI. Instead of storing only the latest location information, each time the newly updated location information is acquired, it is stored in the identification information DB 57 together with the time information And transmits it to the location information DB 61 for updating.

The location information extracting unit 55 inquires the identification information DB 57 with the extracted location information LAC and SAC to check whether there is a location-based service currently in progress at the corresponding location. If there is an ongoing location- Based service providing server 60 transmits a service provision request message including a telephone number (MSISDN) and location information (LAC, SAC) obtained using the TMSI and IMSI to the service provider 63 of the location- Based service.

The location-based service providing server 60 inquires the terminals 10 located at the location based service target location and provides the location based service to the corresponding terminals 10 and includes a location information DB 61, a service providing unit 63 , And a profile storage unit 65. [

Upon receiving the service provision request message requesting the location-based service provision from the location information extraction unit 55 of the location information collection server 50, the service provision unit 63 transmits the service provision request message including the telephone number (MSISDN) is subscribed to the location-based service. If the location-based service is provided as a subscriber-based opt-in service, it is checked whether or not the service is subscribed to the location-based service. On the other hand, if the service is an opt-out service that is not a subscriber-based service, the subscriber list (Blacklist) denied reception of the location-based service is checked and it is confirmed whether the terminal is a service denied service.

If it is confirmed that the service is registered in the location-based service, if the number of services on the same day and the number of services by time are not more than the threshold value, (E.g., a terminal model, a brand, an OS version, an OS type, a terminal type, and the like) corresponding to an MSISDN (e.g., a sex, an age, a job, a religion, a hobby, Based service content based on location information (LAC, SAC (or CI)) included in the service provision request message. And transmits the selected location-based service contents to the corresponding terminal 10 through the content delivery unit 67. [

The content delivery unit 67 transmits the location-based service contents selected for delivery to the terminal 10 according to its type, such as SMS, multimedia message (MMS), unstructured supplementary service data (USSD) Voice Response) to the terminal 10 by using one of them.

The service provider 63 stores and manages geographical location information (for example, Gangnam-gu, Seocho-dong, GPS information) of LAC, SAC, and CI in cooperation with a mobile communication company system.

If the service provider 63 requests the location-based service content (open API or HTTP request) from the terminal 10 via the application or web browser to the service provider 63, the service provider 63 selects the location- The service content is delivered to the user through an open API or an HTTP response.

On the other hand, since the terminal 10 is mobile, it can be moved from one exchange 35 to another exchange 25 and handed over as shown in FIG. When the terminal 10 enters the area supervised by the new exchange 25 and sends an initial UE message for the first location update request to the new exchange 25, The exchange 25 generates and transmits a message with the previous TMSI. After receiving the new TMSI, the exchange 25 transmits the new TMSI to the terminal 10 by including it in the direct transmission message for accepting the location update. The UE 10 having the new TMSI assigned thereto newly generates an initial UE message for a location update request periodically transmitted to the exchange 25 within the same exchange 25 by using the newly allocated TMSI.

Accordingly, when the location information extracting unit 55 receives the direct transmission message for accepting location update from the message collecting unit 53, the location information extracting unit 55 extracts the terminal identification information (TMSI, IMSI), the exchange point code (LU_PC) Extract the number (SEQ). Then, the terminal 10 confirms the stored TMSI and IMSI stored in the identification information DB 57 based on the extracted exchange point code (LU_PC) and the exchange serial number (SEQ) when the terminal 10 requests location registration to the exchange 25. If the TMSI has been changed, the IMSI is stored in the identification information DB 57 based on the new TMSI.

Meanwhile, as described above, if only the TMSI is included in the extracted terminal identification information by analyzing the RANAP message, and if there is no IMSI corresponding to the TMSI in the identification information DB 57, the location information extracted from the RANAP message It can not be immediately applied to services because it can not.

Therefore, in order to make the location information collected through the RANAP message into valid information, the MAP_SEND_IDENTIFICATION request message and the MAP_SEND_IDENTIFICATION response message are analyzed from the MAP (Mobile Application Part) message exchanged between the exchanges 25 and 35, The terminal identification information (IMSI) can be obtained.

As shown in FIG. 2, when the terminal 10 enters the area managed by the new exchange 25 and sends an initial UE message for the first location update request to the new exchange 25, Transmits a MAP_SEND_IDENTIFICATION request message to the previous exchange 35 identified through the Location Area (LA) information of the initial UE message for the update request, and requests the IMSI of the terminal 10 with the previous TMSI. The previous exchange 35 transmits a MAP_SEND_IDENTIFICATION response message to the new exchange 25 to forward the IMSI of the terminal 10 to the new exchange 25.

3 is a diagram schematically illustrating a configuration of a mobile communication system for collecting MAP messages according to an embodiment of the present invention.

3, when the MAP message is received from the router (not shown) (or any one of the tap and the signal distributor) located on the connection line between the exchange 25 and the exchange 35, MAP message, extracts the MAP_SEND_IDENTIFICATION request message and the MAP_SEND_IDENTIFICATION response message, and transmits the extracted message to the location information extracting unit 55. [

Here, the MAP message collection is performed by locating a router (not shown) on a connection line between the exchange 25 and the exchange 35 and then transmitting all the MAP messages exchanged between the exchange 25 and 35 through the router Mirroring, and transmitting the mirrored MAP message to the message collecting unit 53. Then, after the tap (TAP) is positioned on the connection line between the exchange 25 and the exchange 35, all the MAP messages exchanged between the exchange 25 and the exchange 35 are copied through the tap, And to transmit the message to the message collecting unit 53. [ After a signal distributor (for example, an optical distributor) is located on a connection line between the exchange 25 and the exchange 35, all MAP messages exchanged between the exchange 25 and the exchange 35 through the signal distributor The message may be distributed to the message collecting unit 53 and transmitted.

The location information extracting unit 55 extracts the terminal identification information (TMSI, IMSI) from the MAP_SEND_IDENTIFICATION request message and the MAP_SEND_IDENTIFICATION response message received from the message collecting unit 53 and transmits the MAP_SEND_IDENTIFICATION response message to the terminal 10 Acquires the IMSI, maps the acquired IMSI to the TMSI, and stores the IMSI in the identification information DB 57.

4 is a diagram schematically illustrating a configuration of a mobile communication system for collecting MAP messages according to another embodiment of the present invention.

4, when the MAP message is received from the router (not shown) (or any one of the tap and the signal distributor) located on the connection line between the exchange 25 and the home location register 40, Analyzes the received MAP message, extracts the MAP_INSERT_SUBSCRIBER_DATA request message, and transmits the MAP_INSERT_SUBSCRIBER_DATA request message to the location information extracting unit 55.

Here, the MAP message collection is performed by locating a router (not shown) on a connection line between the exchange 25 and the home location register 40 and then switching the home location register 40 and the exchange 25 via the router (not shown) And transmits the mirrored MAP message to the message collecting unit 53. The MAP collecting unit 53 collects the MAP message and transmits the MAP message to the message collecting unit 53. [ The TAP is placed on the connection line between the exchange 25 and the home location register 40 and all the MAP messages exchanged between the exchange 25 and the home location register 40 are copied through the tap , And to transmit the copied MAP message to the message collecting unit 53. After a signal distributor (for example, an optical distributor) is located on the connection line between the exchange 25 and the home location register 40, the home distributor 40 is connected to the home location register 40 via the signal distributor. All MAP messages may be distributed to the message collecting unit 53 and transmitted.

The location information extracting unit 55 obtains the terminal identification information IMSI and the MSISDN of the terminal in the MAP_INSERT_SUBSCRIBER_DATA request message received from the message collecting unit 53 and maps the acquired IMSI and the telephone number MSISDN And stores it in the identification information DB 57.

As described above, in the present embodiment, since the terminal identification information (IMSI) and the telephone number (MSISDN) of the terminal are obtained through the MAP_INSERT_SUBSCRIBER_DATA request message exchanged between the exchange 25 and the home location register 40, (MSISDN) without querying the customer information server or the customer information server.

5 is a diagram schematically illustrating a configuration of a mobile communication system for collecting location information through a RADIUS message according to an embodiment of the present invention.

In FIG. 5, the terminal 10 requests connection to the PS network every time when the terminal 10 is disconnected from the PS network and reconnected (for example, when the power is turned off, then turned on again, or when the terminal 10 leaves the shadow area).

The terminal 10 may be implemented as a terminal capable of accessing a PS network and receiving data services, such as a mobile communication terminal, a smart phone, a tablet PC, and a laptop.

The base station 15 and the base station controller 20 perform the same operations as those of the base station 15 and the base station controller 20 shown in FIG. 1, and a description thereof will be omitted.
