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

First, the 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).

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

TMSI is a value assigned by the exchange or visitor location register (VLR) to prevent the exposure of IMSI in the radio section. When the terminal performs handover during the exchange period and is registered at another exchange, new TMSI is allocated. Receive.

The terminal (user) location information is a location area code (LAC) and a service area code (CAC) or 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.

In FIG. 1, a user equipment (UE) 10 is subscribed to a mobile communication service, and a call (voice) is transmitted from a base station 15 through a reverse and forward wireless link with a base station 15 that manages an area in which it is located. / Text / packet) or the call to the base station (15).

The terminal 10 described above 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 and a smart phone.

The base station (Node B) 15 is connected to the corresponding base station controller 20, respectively, and serves as a relay between the terminal 10 and the base station controller 20 located in its cell area.

A radio network controller (RNC) 20 performs resource allocation, call control, handoff control, voice and packet processing on the base station 15 connected to the base station 15, and the base station 15 itself. It manages base station (base station, cell) information used as location information of terminals 10 attached to the base station.

A mobile switching center (MSC) 25 and 35 is an apparatus for providing a circuit switching service to a mobile subscriber in cooperation with a circuit network, and manages base station controllers 20 connected thereto.

The above-described exchanges 25 and 35 may use mobility information such as location update, location registration, and paging to support mobile communication services using the base station controller 20 and the RANAP message. Perform management (MM).

When the terminal 10 performs Location Registration & Location Update, call origination / reception, and SMS origination / reception, the exchanger 25, 35 transmits a terminal (HLR) to the home location register (HLR) 40. 10) Register or update the location information. 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.

At call setup, the originating exchange 35 queries the home location register 40 for the location of the destination exchange and, accordingly, sends a RANAP message to the destination exchange 25. The destination exchange 25 receiving the RANAP message transfers it to the base station controller 20 to which the terminal 10 belongs, the base station controller 20 passes it back to the base station 15, and the base station 15 propagates The call setup signaling message is transmitted to the called terminal by sending a.

The router 30 mirrors all RANAP messages exchanged between the base station controller 20 and the exchanger 25 for incoming / outgoing call processing, location registration processing, etc. of the terminal 10, and the mirrored messages are collected by the location information collecting server. 50 to the message collection unit 53.

As described above, all the RANAP messages transmitted and received between the base station controller 20 and the exchanger 25 in the router 30 are mirrored using the port mirroring function of the router 30, and the mirrored RANAP message is messaged. In addition to the method of transmitting to the collecting unit 53, after placing a tap (TAP) on the connection line between the base station controller 20 and the exchange, all the exchange between the base station controller 20 and the exchange 25 through the tap It may be implemented to copy the RANAP message and to transmit the copied RANAP message to the message collector 53, and to connect a signal splitter (e.g., optical splitter) to the connection line between the base station controller 20 and the switch 25. After positioning, all 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 collector 53 and transmitted.

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

When the message collecting unit 53 receives 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. The extracted message is transmitted to the location information extraction unit 55.

The above-described message collector 53 analyzes the RANAP message received from the router 30 (or any one of taps and signal distributors) and analyzes an initial UE message for a location updating request. Initial UE Message for Connection Management (CM) Service Request, Initial UE Message for Paging Response, Direct Transfer Message for Location Updating Accept ( Direct Transfer Message) and only the paging request message (Paging Request Message) is extracted and transferred to the location information extraction unit 55.

Here, the message collecting unit 53 identifies the message structure and parameter information defined in the protocol to classify the message, and the initial UE message uses the message type included in the non-access stratum (NAS) payload of the initial UE message. Whether the initial UE message is an initial UE message for location update request, an initial UE message for CM service request, or an initial UE message for paging response may be distinguished.

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

The location information extracting unit 55 extracts the terminal identification information (IMSI, TMSI) and the location information (LAC, SAC (or CI)) from the message received from the message collecting unit 53, and then extracts the terminal identification information (IMSI). , The mobile station International ISDN Number (MSISDN) is obtained from the identification information DB 57 using the TMSI, the acquired telephone number (MSISDN) and the extracted location information (LAC, SAC (or CI)) ) Is mapped to the location information DB 61 of the location-based service providing server 60 and stored.

When the above-described location information extracting unit 55 receives the paging request message 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. In addition, if the extracted terminal identification information includes TMSI in addition to the IMSI essentially included in the paging request message, and if both the IMSI and the TMSI are included, the IMSI and the TMSI are mapped to the identification information DB 57. After storing, the telephone number MSISDN is obtained from the identification information DB 57 using IMSI. When only the IMSI is included, the phone number 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), request a telephone number (MSISDN) query to the location information DB 61 of the location-based service providing server 60 using the IMSI, the location in response The telephone number MSISDN is obtained from the information DB 61. Here, the location information DB 61 collects and manages IMSI and phone number (MSISDN) mapping information periodically by interworking with the customer information server of the mobile communication company, and the phone number (MSISDN) for the IMSI requested by the location information extraction unit 55. If there is no), request the inquiry to the customer information server to update in real time the phone number (MSISDN) for the corresponding IMSI, and sends a response to the location information extraction unit 55.

As described above, the location information extracting unit 55 that obtains the phone number MSISDN using the terminal identification information IMSI is obtained by extracting the location information (extracted with the terminal identification information and the phone number MSISDN of the obtained terminal). LACs are mapped and stored in the location information DB 61. The location information extraction unit 55 maps the acquired phone number MSISDN and location information LAC to the identification information DB 57.

On the other hand, the location information extractor 55 receives 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 collector 53. Terminal identification information (IMSI, TMSI) and location information (LAC, SAC) are extracted from the received message. Also, if the extracted terminal identification information includes the IMSI in addition to the TMSI, and if only the TMSI is included, the IMSI is retrieved from the identification information DB 57 using the TMSI, and the identification information DB (using the retrieved IMSI) is used. 57) obtain a phone number (MSISDN). When the extracted terminal identification information includes the IMSI in addition to the TMSI, the 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, request a telephone number (MSISDN) query to the location information DB 61 using the IMSI, and in response to the telephone number (MSISDN) from the location information DB 61 MSISDN). If the message received from the message collector 53 is an initial UE message for requesting a location update, the location information extractor 55 and the exchange point code LU_PC included in the extracted location information LAC and SAC may be used. TMSI and IMSI are mapped and stored in 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 the location update later from the message collecting unit 53, it confirms that the two messages are in the same continuity, and if the TMSI value is changed, This is to check and update.

As described above, the location information extracting unit 55 having obtained the phone number MSISDN by using the terminal identification information TMSI and IMSI is extracted with the terminal number MSISDN of the acquired terminal and the terminal identification information. The information (LAC, SAC) is mapped and stored in the location information DB 61. And the phone number (MSISDN) and location information (LAC, SAC) of the obtained terminal is mapped and stored in the identification information DB (57).

The aforementioned location information extractor 55 identifies the terminal extracted from the initial UE message for the location update request, the initial UE message for the CM service request, or the initial UE message for the paging response received from the message collector 53. If only the TMSI is included in the information, IMSI is obtained by querying the identification information DB 57 with the TMSI, but there is a case where the corresponding TMSI does not exist in the identification information DB 57. In this case, the location information extraction unit 55 stores the TMSI and the extracted location information (LAC, SAC) in the identification information DB 57. For example, the terminal 10 has entered an exchange area of a regional office and sent an initial UE message for requesting a location update for location registration to the exchange 25, but has not yet received an incoming call or an incoming SMS. May not be stored in the identification information DB (57). In this case, the location information extraction unit 55 stores the location information (LAC, SAC) for the TMSI in the identification information DB 57, and later obtains the IMSI for the TMSI, the telephone number based on the IMSI. (MSISDN) is obtained and location information is updated in the location information DB 61 using this telephone number MSISDN. At this time, before acquiring IMSI, TMSI-based location information can be received several times. Instead of storing only the latest location information, it is accumulated in the identification information DB 57 along with time information every time the newly updated location information is acquired. The data can be transmitted to the position information DB 61 for updating.

The location information extraction unit 55 queries the identification information DB 57 with the extracted location information (LAC, SAC) and checks whether there is a location-based service currently in progress at the corresponding location, and identifies the terminal if there is a location-based service currently in progress. The service providing request message including the telephone number (MSISDN) and location information (LAC, SAC) obtained by using the information (TMSI, IMSI) is transmitted to the service providing unit 63 of the location-based service providing server 60 Request to provide location based services.

The location-based service providing server 60 queries the terminals 10 located in the location-based service target location and provides location-based services to the terminals 10. The location information DB 61 and the service provider 63 ), The profile storage unit 65 is included.

When the service provider 63 receives the service providing request message for requesting the location-based service from the location information extracting unit 55 of the location information collecting server 50, the telephone number included in the service providing request message. It is checked whether the terminal 10 corresponding to the MSISDN is subscribed to the location-based service. As such, when providing the location-based service as a subscriber-based opt-in service, it is checked whether the location-based service is subscribed to. On the other hand, in the case of an opt-out service rather than a subscriber-based service, the terminal checks whether the terminal refuses to receive the service by checking a subscriber list (Blacklist) that refuses to receive the location-based service.

If the result of the check is subscribed to the location-based service, and the number of services per day and the number of services per time zone are not greater than or equal to each threshold based on the service setting information, that is, the number of services per day and the number of services per time zone are each threshold value. If smaller, the service provider 63 may work in conjunction with the profile storage unit 65 to provide an optimal service to the user, for example, user information corresponding to the telephone number MSISDN (eg, gender, age, occupation, Religion, hobbies, plans, etc.) and device information (e.g., device model, brand, OS version, OS type, device type, etc.) and location information (LAC, SAC (or CI)) included in the service request message. Select location-based service content based on. The service provider 63 transmits the selected location-based service content to the corresponding terminal 10 through the content delivery unit 67.

The above-described content delivery unit 67 according to the type of location-based service content selected for delivery to the terminal 10 according to the form of a short message (SMS), multimedia message (MMS), USSD (Unstructured Supplementary Service Data), IVR (Interactive) Voice Response) is transmitted to the terminal 10 using any one.

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

In addition, the service provider 63 selects the location-based service content when a location-based service content request (open API or HTTP request) is received from the terminal 10 to the service provider 63 through an application or a web browser. Service contents are delivered to users through open API or HTTP response.

On the other hand, since the terminal 10 is mobile, as shown in FIG. 2, the terminal 10 may be moved from one switch 35 to another switch 25 to be handed over. When the terminal 10 enters the area governed by the new exchange 25 and transmits an initial UE message for a location update request to the new exchange 25 for the first time, the terminal 10 receives an assignment from the previous exchange 35. After generating and transmitting a message with the previous TMSI, the exchange 25 receives the new TMSI and transmits it to the terminal 10 by including it in a direct transmission message for accepting a location update. As such, the new terminal 10 allocated with the new TMSI generates an initial UE message with the newly assigned TMSI for the location update request to the exchange 25 periodically in the area of the same exchange 25.

Therefore, when the location information extracting unit 55 receives the direct transmission message for accepting the location update from the message collecting unit 53, the terminal identification information (TMSI, IMSI), the exchange point code (LU_PC), and the exchange series in the corresponding message. Extract the number (SEQ). The location information extracting unit 55 may request the terminal 10 to register the location to the switch 25 in the identification information DB 57 based on the extracted switch point code LU_PC and the switch serial number SEQ. Check the saved TMSI and IMSI. If the TMSI is changed as a result of the check, the location information extraction unit 55 stores the IMSI in the identification information DB 57 based on the new TMSI.

On the other hand, as described above, if the terminal identification information extracted by analyzing the RANAP message includes only TMSI, and there is no IMSI corresponding to the TMSI in the identification information DB 57, whose location information is extracted from the RANAP message. Because it is unknown, it cannot be applied to the service immediately.

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 in the MAP (Mobile Application Part) messages exchanged between the exchanges 25 and 35 to change the exchange of the terminal 10. According to the terminal identification information (IMSI) can be obtained.

As shown in FIG. 2, when the terminal 10 enters the domain controlled by the new exchange 25 and transmits an initial UE message for a location update request to the new exchange 25 for the first time, the new exchange 25 is located. The MAP_SEND_IDENTIFICATION request message is transmitted to the previous exchange 35 identified through the location area (LA) information of the initial UE message for the update request, but requests the IMSI of the terminal 10 with the previous TMSI. In response to this, the previous exchange 35 transmits a MAP_SEND_IDENTIFICATION response message to the new exchange 25 to deliver the IMSI of the terminal 10.

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

In FIG. 3, when the message collector 53 receives a MAP message from a router (or a tap or a signal distributor) located in a connection line between the exchanger 25 and the exchanger 35, the message collector 53 receives the MAP message. The MAP message is analyzed to extract the MAP_SEND_IDENTIFICATION request message and the MAP_SEND_IDENTIFICATION response message, and the extracted message is transmitted to the location information extraction unit 55.

Here, the MAP message collection places a router (not shown) on the connection line between the exchange 25 and the exchange 35, and then transfers all MAP messages exchanged between the exchanges 25 and 35 through the router (not shown). Mirror and transmit the mirrored MAP message to the message collector 53. And after placing a tap (TAP) on the connection line between the exchange 25 and the exchange 35, through this tap to copy all the MAP messages exchanged between the exchange 25 and the exchange 35, the copied MAP The message may be implemented to transmit the message to the message collector 53. Then, after placing a signal splitter (for example, an optical splitter) on the connection line between the switch 25 and the switch 35, all MAP messages exchanged between the switch 25 and the switch 35 through the signal splitter are transmitted. The message collection unit 53 may be distributed to transmit the message.

The location information extracting unit 55 extracts 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 requests the location registration to the exchanger 25 of the terminal 10. The IMSI is obtained, and the acquired IMSI is mapped to the TMSI and stored in the identification information DB 57.

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

In FIG. 4, when the message collector 53 receives a MAP message from a router (or a tap or a signal splitter) located in a connection line between the exchanger 25 and the home location register 40, After analyzing the received MAP message, the MAP_INSERT_SUBSCRIBER_DATA request message is extracted, and the information is transferred to the location information extraction unit 55.

Here, the MAP message is collected by placing a router (not shown) on the connection line between the switch 25 and the home location register 40, and then switching the switch 25 and the home location register 40 through the router (not shown). It is possible to mirror all MAP messages sent and received between the two, and to transmit the mirrored MAP message to the message collector 53. And after placing a tap (TAP) on the connection line between the exchange 25 and the home location register 40, through this tab to copy all the MAP messages exchanged between the exchange 25 and the home location register 40 In addition, the copied MAP message may be implemented to be transmitted to the message collector 53. And placing a signal splitter (e.g., an optical splitter) on a connection line between the exchanger 25 and the home location register 40, and then exchanging between the exchanger 25 and the home location register 40 via the signal splitter. All MAP messages may be distributed to the message collector 53 and transmitted.

The location information extraction unit 55 obtains the terminal identification information (IMSI) and the terminal's telephone number (MSISDN) from the MAP_INSERT_SUBSCRIBER_DATA request message received from the message collector 53, and maps the obtained IMSI and the telephone number (MSISDN). In the identification information DB 57.

As such, in the present embodiment, since the terminal identification information (IMSI) and the terminal's telephone number (MSISDN) are obtained through the MAP_INSERT_SUBSCRIBER_DATA request message exchanged between the exchange 25 and the home location register 40, the location-based service providing server 60 It is possible to obtain a phone number (MSISDN) without having to search 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 a connection to the PS network whenever it is disconnected from the PS network and then reconnected (for example, when the power is turned off and then on again, out of the shadow area).

The terminal 10 may be implemented as a terminal capable of receiving a data service by accessing a PS network such as a mobile communication terminal, a smartphone, a tablet PC, a laptop, and the like.

Since the base station 15 and the base station controller 20 perform the same operations as the base station 15 and the base station controller 20 of FIG. 1, description thereof will be omitted.

When the terminal 10 requests a PS network connection, the packet gateway 70 performs authentication on the terminal 10 by exchanging an RADIUS protocol-based authentication message (Access-Request & Access Accept) with the AAA server 75. After that, IP is assigned to the terminal 10, the AAA server 75 exchanges a charging message based on the RADIUS protocol, and determines whether the user provides the data service, and the data to the terminal 10 allowed to provide the data service. Send and receive traffic.

As such, the packet gateway 70 allocates an IP according to the network access request of the terminal 10 and then requests the AAA server 75 to ask whether the terminal 10 provides a wireless data service (Account Start). Request) message is sent, and a charging start response message is received in response. If the terminal 10 does not use the wireless data service for a predetermined time, the terminal 10 detects this, releases the radio network resource allocated to the terminal 10, and then sends an account stop request message to the AAA server 75. Transmits, and receives a charging end response message in response thereto.

The aforementioned packet gateway 70 may be implemented as a Gateway GPRS Support Node (GGSN) in a 3G network, and may be implemented as a PDN Gateway (P-GW) in an LTE network.

The AAA server 75 performs authentication, authorization and accounting functions.

The router 80 mirrors all RADIUS messages exchanged between the packet gateway 70 and the AAA server 75 and transmits the mirrored messages to the message collector 53 of the location information collection server 50.

As described above, all the RADIUS messages transmitted and received between the packet gateway 70 and the AAA server 75 in the router 80 are mirrored using the port mirroring function of the router 80, and the mirrored RADIUS messages are collected by the message collector ( 53, a tap (TAP) is placed on the connection line between the packet gateway 70 and the AAA server 75, and then exchanged between the packet gateway 70 and the AAA server 75 through the tap. It can be implemented to copy all incoming RADIUS messages and to send the copied RADIUS messages to the message collector 53, or a signal splitter (e.g., optical fiber) on the connection line between the packet gateway 70 and the AAA server 75. After the distributor is located, all the RADIUS messages exchanged between the packet gateway 70 and the AAA server 75 through the signal distributor may be distributed to the message collector 53 for transmission.

When the message collecting unit 53 of the location information collecting server 50 receives a RADIUS message from the router 80 (or any one of a tap and a signal distributor), the message collecting unit 53 analyzes the received RADIUS message and analyzes the location information of the terminal 10. Only the message used for confirmation is extracted and the extracted message is transmitted to the location information extraction unit 55.

The message collecting unit 53 analyzes the RADIUS message received from the router 80 (or any one of the tap and the signal distributor), extracts only the charging start request message and the charging end request message, and extracts the location information extracting unit 55. To pass).

At this time, the message collecting unit 53 not only receives the RADIUS message from the router 80 (or any one of taps and signal distributors) installed in the PS network, but also from the router 30 (or tap and signal distributors) installed in the CS network. It can be implemented to receive a RANAP message from either).

The location information extracting unit 55 extracts the terminal identification information (IMSI), the location information (LAC, CI) and the telephone number (MSISDN) from the message received from the message collecting unit 53, and then extracts the terminal identification information (IMSI). ), Location information (LAC, CI) and phone number (MSISDN) is mapped and stored in the identification information DB (57). And the phone number (MSISDN) and the extracted location information (LAC, CI) is mapped to the location information DB (61) and stored.

And the location information extraction unit 55 checks the identification information DB (57) with the extracted location information (LAC, CI) to check whether there is a location-based service currently in progress at the corresponding location, and if there is a location-based service currently in progress, the phone number ( The service providing request message including the MSISDN) and the location information (LAC, CI) is transmitted to the service providing unit 63 of the location based service providing server 60 to request the location based service.

Since the service provider 63 performs the same operation as the service provider 63 of FIG. 1, a description thereof will be omitted.

6 is a flowchart illustrating a method of collecting location information according to an embodiment of the present invention.

First, when an incoming call connection for a voice call, a text message (SMS), etc. is requested to the terminal (user) 10, a paging request message, which is a kind of RANAP message, from the destination exchanger 25 of the CS network to the destination base station controller 20. (Paging Request Message) is transmitted (S10).

When the terminating exchange 25 transmits a paging request message to the terminating base station controller 20 through the process S10, the router 30 mirrors all RANAP messages exchanged between the exchange 25 and the base station controller 20. The mirror is transmitted to the message collecting unit 53 of the location information collecting server 50 (S12 and S14). The paging request message transmitted from the destination exchanger 25 to the destination base station controller 20 in step S10 is transmitted to the destination base station controller 20 as the destination through the router 30 without modification.

In the exemplary embodiment of the present invention, all the RANAP messages exchanged between the exchanger 25 and the base station controller 20 in the router 30 are mirrored using the port mirroring function of the router 30, and the mirrored RANAP message is collected by the message collector. The transmission to 53 will be described as an example. However, in addition to copying all the RANAP messages exchanged between the exchanger 25 and the base station controller 20 in the tap located on the connection line between the switch 25 and the base station controller 20, the copied RANAP message is copied to the message collector ( 53, and may be exchanged between the exchanger 25 and the base station controller 20 at a signal splitter (e.g., an optical splitter) located on a connection line between the exchanger 25 and the base station controller 20. All RANAP messages may be distributed to the message collector 53 and transmitted.

The message collector 53 receiving the RANAP message from the router 30 (or any one of the tap and the signal distributor) through the process S14 analyzes the received RANAP message and uses the terminal 10 to confirm the location information. The paging request message, which is a message, is extracted and transferred to the location information extracting unit 55 (S16).

The location information extraction unit 55 receiving the paging request message through the process S16 extracts the terminal identification information IMSI and the location information LAC from the received paging request message (S18). The paging request message essentially includes IMSI, which is one of terminal identification information.

Therefore, the location information extraction unit 55 checks whether the TMSI is included in addition to the IMSI included in the extracted terminal identification information (S20).

If the terminal identification information extracted as a result of the check in step S20 includes TMSI in addition to the IMSI, the IMSI and TMSI are mapped and stored in the identification information DB 57 (S22), and then the identification information DB (57) is used using the IMSI. Search for the telephone number (MSISDN) in the (S24).

On the other hand, if only the IMSI is included in the extracted terminal identification information as a result of the check in step S20, the location information extraction unit 55 retrieves the telephone number MSISDN from the identification information DB 57 using the IMSI ( S24).

If the phone number MSISDN is not found in the search result identification information DB 57 of step S24, the location information extraction unit 55 provides a location-based service providing server 60 that provides a location-based service using IMSI. Request a phone number (MSISDN) inquiry to the location information DB (61) (S26, S28).

The location information DB 61, which has been requested to retrieve the phone number (MSISDN) through the process S28, searches for the phone number (MSISDN) by IMSI (S30), and then retrieves the phone number (MSISDN) in response to the phone number inquiry request. ) Is transmitted to the location information extracting unit 55 (S38).

Here, the location information DB 61 periodically collects and manages IMSI and telephone number (MSISDN) mapping information in association with the customer information server 85 of the mobile communication company, and then calls the IMSI from the location information extraction unit 55. If there is a request for a number lookup, a response is sent. And if there is no phone number (MSISDN) for the IMSI requested by the location information extraction unit 55 (S30: No), request the customer information server 85 to query the real-time phone number (MSISDN) for the corresponding IMSI and In operation S32 to S36, a response is sent to the location information extracting unit 55 according to the updated contents (S38).

The location information extracting unit 55, which has obtained the phone number MSISDN through steps S28 to S38, maps the obtained phone number MSISDN and the terminal identification information IMSI and stores it in the identification information DB 57. (S40), the obtained telephone number (MSISDN) and the location information (LAC) extracted in the above-described process S18 is mapped and stored in the location information DB 61 (S42).

In addition, the location information extracting unit 55 maps the acquired phone number MSISDN and the location information LAC extracted in step S18 and stores it in the identification information DB 57 (S44).

Thereafter, the location information extraction unit 55 searches for the identification information DB 57 based on the location information LAC extracted through the process S18, and is activated in association with the location corresponding to the extracted location information LAC. Check whether there is a location-based service (S46, S48).

If there is an activated location-based service as a result of checking in step S48, the location information extracting unit 55 uses the telephone number MSISDN and the location information LAC to provide the service of the location-based service providing server 60. The service 63 transmits a service providing request message for requesting location based service provision (S50).

The location information extractor 55 checks whether there is an activated location-based service in association with the location corresponding to the extracted location information LAC, and omits the procedure of requesting the location-based service to the service provider 63. It may be.

7 is a flowchart illustrating a method of collecting location information according to another embodiment of the present invention.

The RANAP message transmitted from the base station controller 20 to the switch 25 includes an initial UE message for a location update request, an initial UE message for a CM service request, and an initial UE message for a paging response. Transmits one of an initial UE message for a location update request, an initial UE message for a CM service request, and an initial UE message for a paging response to the switch 25 (S110), the switch 25 and the base station controller ( 20) the router 30 mirroring all the RANAP messages exchanged between the two and transmits them to the message collection unit 53 of the location information collection server 50 by mirroring them (S112 and S114).

In step S112, in addition to the router 30, all the RANAP messages transmitted and received between the exchanger 25 and the base station controller 20 are copied and copied in a tap located on a connection line between the exchanger 25 and the base station controller 20. The RANAP message to the message collector 53 and may be implemented in a signal splitter (eg, optical splitter) located at a connection line between the switch 25 and the base station controller 20. All RANAP messages exchanged between the base station controller 20 may be distributed to the message collector 53 and transmitted.

The message collector 53 receiving the RANAP message from the router 30 (or any one of a tap and a signal distributor) through the process S114 may analyze the received RANAP message and use the terminal 10 to confirm the location information. Any one 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 is extracted and transferred to the location information extracting unit 55 (S116).

The location information extraction unit 55 receiving any one of an initial UE message for a location update request, an initial UE message for a CM service request, and an initial UE message for a paging response through the process S116 described above is performed by the terminal. Identification information and location information (LAC, SAC) is extracted (S118). 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 include TMSI, LAC, and SAC information. In exceptional cases, if the TMSI has expired, a message is generated using IMSI.

Therefore, the location information extraction unit 55 checks whether the extracted terminal identification information includes the IMSI in addition to the TMSI (S120).

When only the TMSI is confirmed as the result of the process S120 described above, the location information extracting unit searches for the IMSI in the identification information DB 57 using the TMSI (S122).

When the IMSI is searched for in the identification information DB 57 by using the TMSI in step S122 described above, if the IMSI is not present in the identification information DB 57, the location information extracting unit 55 performs the TMSI and the step S118. The extracted location information (LAC, SAC) is mapped and stored in the identification information DB (57).

On the other hand, if the check result of step S120 includes the IMSI in addition to the TMSI, it is checked whether the message received from the message collector 53 through the step S116 is the initial UE message for the location update request (S124). .

If the message received from the confirmation result message collection unit 53 of step S124 is the initial UE message for the location update request, the exchange point code included in the location information (LAC, SAC) extracted through step S118 described above. The IMSI and the TMSI are mapped and stored in the identification information DB 57 based on the LU_PC and the exchange serial number (SEQ) (S126).

Thereafter, the location information extraction unit 55 retrieves the telephone number MSISDN from the identification information DB 57 by using IMSI (S128).

If the phone number MSISDN is not found in the search result identification information DB 57 of step S128 (S130: No), the location information extracting unit 55 uses the IMSI as in the embodiment of FIG. In order to obtain and request a phone number (MSISDN) inquiry to the location information DB 61 (S132), a detailed description thereof will be omitted.

The location information extracting unit 55, which has obtained the phone number MSISDN through step S128 or step S132, maps the acquired phone number MSISDN and location information LAC and SAC extracted in step S118. The location information is stored in the DB 61 (S134), the phone number MSISDN is mapped to the location information (LAC, SAC) extracted in step S118, and stored in the identification information DB 57 (S136).

Thereafter, the location information extracting unit 55 searches for the identification information DB 57 based on the location information LAC and SAC extracted through the process S118, and corresponds to the extracted location information LAC and SAC. Check whether there is an activated location-based service in association with (S138, S140).

If there is an activated location-based service as a result of checking in step S140, the location information extraction unit 55 of the location-based service providing server 60 using the phone number (MSISDN) and location information (LAC, SAC) The service providing unit 63 transmits a service providing request message for requesting location-based service providing (S142).

The location information extractor 55 checks whether there is an activated location-based service in association with the location corresponding to the extracted location information LAC and SAC, and requests the service provider 63 to provide the location-based service. May be omitted.

8 is a flowchart illustrating a procedure of updating terminal identification information according to an embodiment of the present invention.

First, when the switch 25 transmits a direct transmission message for accepting a location update from the switch 25 to the base station controller 20 (S210), the router 30 mirrors all RANAP messages exchanged between the switch 25 and the base station controller 20. ) Mirrors it and transmits it to the message collector 53 of the location information collection server 50 (S212, S214).

In step S212, in addition to the router 30, all the RANAP messages exchanged between the switch 25 and the base station controller 20 in a tap located on a connection line between the switch 25 and the base station controller 20 are copied and copied. The RANAP message to the message collector 53 and may be implemented in a signal splitter (eg, optical splitter) located at a connection line between the switch 25 and the base station controller 20. All RANAP messages exchanged between the base station controller 20 may be distributed to the message collector 53 and transmitted.

The message collector 53 receiving the RANAP message from the router 30 (or any one of a tap and a signal distributor) through the process S214 analyzes the received RANAP message and uses the terminal 10 to check the location information. The direct transmission message for the location update acceptance, which is the message, is extracted and transferred to the location information extraction unit 55 (S216).

The location information extracting unit 55 receiving the direct transmission message for accepting the location update through the process S216 may include the terminal identification information (TMSI, IMSI), the exchange point code (LU_PC), which is the location information, and the serial number of the exchange in the received message. Extract the number (SEQ) (S218)

Thereafter, the previous TMSI and IMSI stored in the identification information DB 57 are searched based on the extracted exchange point code LU_PC and the exchange serial number SEQ (S220).

In addition, it is checked whether the TMSI is changed by comparing the TMSI included in the terminal identification information extracted in the step S218 and the previous TMSI searched in the step S220 (S222).

If the TMSI has been changed as a result of the checking in step S222, the IMSI is stored in the identification information DB 57 based on the TMSI included in the terminal identification information extracted in step S218 (S224).

9 is a flowchart illustrating a procedure of updating terminal identification information according to another embodiment of the present invention.

First, as shown in FIG. 2, when the exchanger 25 receives a location registration request from a newly entered terminal 10 in the domain controlled by the exchanger 25, the previous exchanger identified through the location information included in the location registration request message ( 35), the MAP_SEND_IDENTIFICATION request message including the previous TMSI is transmitted to request the IMSI of the terminal 10. In response to this, the previous exchange 35 transmits to the new exchange 25 the IMSI of the terminal 10 in the MAP_SEND_IDENTIFICATION response message.

As such, the router 31 (or any one of taps and signal splitters) located on a connection line between the switches 25 and 35 mirrors (or copies) MAP messages exchanged between the switches 25 and 35 of the CS network. Distribution) to transmit to the message collection unit 53 of the location information collection server 50 (S310 to S314).

The message collector 53 receiving the MAP message from the router 31 (or any one of a tap and a signal distributor) through the process S314 analyzes the received MAP message and extracts a MAP_SEND_IDENTIFICATION request message and a MAP_SEND_IDENTIFICATION response message. This is transmitted to the location information extraction unit 55 (S316).

The location information extraction unit 55 receiving the MAP_SEND_IDENTIFICATION request message and the MAP_SEND_IDENTIFICATION response message from the message collector 53 through the process S316 analyzes the MAP_SEND_IDENTIFICATION request message and the MAP_SEND_IDENTIFICATION response message and requests the location registration to the exchange 25. The previous TMSI and IMSI of the terminal 10 are extracted (S318).

Thereafter, the location information extraction unit 55 maps the previous TMSI and IMSI extracted in step S318 and stores them in the identification information DB 57 (S320).

Through the above-described series of processes, the IMSI for all terminals 10 can be checked, and the location information of the terminal checked through the RANAP message can be reflected in the location-based service in real time.

10 is a flowchart illustrating a procedure of updating terminal identification information according to another embodiment of the present invention.

First, as shown in FIG. 2, the new exchanger 25, which has confirmed the IMSI of the terminal 10 requesting location registration from the previous exchanger 35, updates the location information of the terminal 10 in association with the home location register 40. Among the routers 32 (or taps or signal splitters) located in a connection line between the exchanger 25 and the home location register 40, the MAP message exchanged between the exchanger 25 and the home location register 40 of the CS network is performed. Any one) is mirrored (or copied, distributed) and transmitted to the message collector 53 of the location information collection server 50 (S410 to S414).

The message collector 53 receiving the MAP message from the router 32 (or any one of taps and signal splitters) through the process S414 extracts the MAP_INSERT_SUBSCRIBER_DATA request message by analyzing the received MAP message, and stores the location information. Transfer to the extraction unit 55 (S416).

The location information extraction unit 55 receiving the MAP_INSERT_SUBSCRIBER_DATA request message from the message collecting unit 53 through the process S416 described above analyzes the MAP_INSERT_SUBSCRIBER_DATA request message and calls the IMSI and the telephone of the terminal 10 requesting the location registration to the exchange 25. The number MSISDN is extracted (S418).

Thereafter, the IMSI extracted from the process S418 and the phone number MSISDN are mapped and stored in the identification information DB 57 (S420).

Since the IMSI and the phone number MSISDN can be obtained through the above-described process, the location-based service providing server 60 or the customer information server as shown in FIGS. 6 and 7 may be used to obtain the phone number MSISDN. You do not need to query.

11 is a flowchart for explaining a method of collecting location information according to another embodiment of the present invention.

First, when the terminal 10 to receive the wireless data service requests access to the PS network, the packet gateway 70 requests the AAA server 75 to ask whether the terminal 10 provides the wireless data service. After transmitting a message and receiving a charging start response message in response thereto, if the terminal 10 does not use the wireless data service for a predetermined time, it detects this and releases the radio network resource allocated to the terminal 10. In operation S510, the AAA server 75 transmits an accounting stop request message to the AAA server 75, and receives an accounting termination response message in response thereto.

When the packet gateway 70 transmits the charging start / end request message to the AAA server 75 through the process S510, the router mirrors all RADIUS messages exchanged between the packet gateway 70 and the AAA server 75 ( 80, the mirror is transmitted to the message collection unit 53 of the location information collection server 50 (S512 and S514).

In the embodiment of the present invention, using the port mirroring function of the router 80 mirrors all RADIUS messages exchanged between the packet gateway 70 and the AAA server 75 at the router 80 and collects the mirrored RADIUS messages. The transmission to the unit 53 will be described as an example. However, in addition, the tap located on the connection line between the packet gateway 70 and the AAA server 75 copies all the RADIUS messages sent and received between the packet gateway 70 and the AAA server 75 and collects the copied RADIUS messages. The packet gateway 70 and the AAA server 75 may be implemented in a signal distributor (for example, an optical splitter) located in a connection line between the packet gateway 70 and the AAA server 75. All RADIUS messages exchanged between the two nodes may be distributed to the message collector 53 and transmitted.

The message collector 53 receiving the RADIUS message from the router 80 (or any one of a tap and a signal splitter) through the process S514 may analyze the received RADIUS message to determine a charge start request message and a charge end request message. The extracted information is transferred to the location information extracting unit 55 (S516).

The location information extraction unit 55 receiving the charging start request message, the charging end request message from the message collecting unit 53 through the process S516, the terminal identification information (IMSI) in the charging start request message, the charging end request message, Location information (LAC, CI), telephone number (MSISDN) is extracted (S518).

And the terminal identification information (IMSI), location information (LAC, CI) and the phone number (MSISDN) extracted through the above step S518 is mapped and stored in the identification information DB 57 (S520), and the above step S518 Mapping the extracted phone number (MSISDN) and the location information (LAC, CI) is stored in the location information DB 61 of the location-based service providing server 60 (S522).

Thereafter, the location information extracting unit 55 searches for the identification information DB 57 based on the location information LAC and CI extracted through the process S518, and corresponds to the extracted location information LAC and CI. Check whether there is an activated location-based service in association with (S524, S526).

If there is an activated location-based service as a result of checking in step S526, the location information extraction unit 55 of the location-based service providing server 60 using the phone number (MSISDN) and location information (LAC, CI) In operation S528, the service providing unit 63 transmits a service providing request message for requesting location based service providing.

The location information extractor 55 checks whether there is an activated location-based service in association with the location corresponding to the extracted location information LAC and CI, and requests the service provider 63 to provide the location-based service. May be omitted.

12 is a flowchart illustrating a location-based service providing method according to the present invention.

First, the service providing unit 63 of the location-based service providing server 60 locates from the location information extracting unit 55 of the location information collection server 50 through any one of the processes S50, S142, and S528 described above. When the base service is requested to be provided (S610), it is checked whether the terminal 10 corresponding to the telephone number MSISDN included in the service providing request message is subscribed to the location based service (S612).

When providing the location-based service as a subscriber-based opt-in service as in step S612 described above, it is determined whether the terminal 10 is subscribed to the location-based service. On the other hand, in the case of providing the location-based service as an opt-out service rather than a subscriber-based service, it checks the subscriber list (Blacklist) that has refused to receive the location-based service to check whether the terminal refuses to receive the service.

If the terminal 10 is subscribed to the location-based service as a result of the checking of the process S612, it is checked whether the number of services per day is greater than or equal to the maximum number of services per day based on the service setting information (S614).

If the number of services per day is not greater than or equal to the maximum number of services per day, that is, if the number of services per day is less than the maximum number of services per day, check whether the number of services per time zone is greater than or equal to the maximum number of services per time zone. (S616).

As a result of the check of the process S616, if the number of service by time zone is not greater than or equal to the maximum service time by time zone, that is, when the number of service by time zone is smaller than the maximum service time by time zone, the advertiser works with the profile storage unit 65. User information (e.g., gender, age, occupation, religion, hobbies, plans, etc.) corresponding to target customer information and phone number (MSISDN) preset by location-based service content, and terminal information (e.g., terminal model) , Brand, OS version, OS type, terminal type, etc.) and location information (LAC, SAC (or CI)) included in the service provision request message is compared to search for location-based service content to be provided to the user (S618). In operation S620, location-based service content for providing an optimal service to a user is selected from the searched location-based service content.

Thereafter, the location-based service content selected in step S620 is transferred to the terminal 10 through the content delivery unit 67 (S622 to S628).

The service providing unit 63 which has transmitted the contents to the terminal 10 through the above steps S622 to S628 increases the number of services per day and the number of times of service corresponding to the corresponding time slot 1 by 1 (S630). A message indicating that the location-based service has been provided to the information extracting unit 55 is transmitted in response to the service providing request message (S632).

Location information collection method and server, location-based service providing method and server of the present invention is not limited to the above-described embodiment can be implemented in various modifications within the scope of the technical idea of the present invention.
