2 is a diagram illustrating a network configuration of a location based service system for obtaining location information of a mobile subscriber according to an embodiment of the present invention.

As shown in FIG. 2, a location-based service system according to the present invention includes a base station (BTS / NodeB) 203, a base station controller (BSC / RNC) 205, an exchange, or a Serving GPRS Support Node (SGSN) (CDMA). In the case of PDSN (Packet Data Servie Node) (hereinafter referred to as exchange / SGSN) 207, home location register 209, operation server (O & M server: Operation and Management) 211, data collection server 213 And location management server 215.

The base station 203 performs radio signal transmission and reception, system synchronization (GPS), radio channel encoding and decoding, baseband signal processing, diversity (space), radio resource management, and self maintenance. The base station controller 205 performs functions such as matching with the base station 203, intercell handover processing, call control, and the like, and one base station controller 205 controls several base stations 203.

In particular, when the mobile communication terminal 201 performs location registration, the base station controller 205 transmits a location registration message to the exchange / SGSN 207 and simultaneously transmits a location registration message to the operation server 211. In addition, the base station controller 205 receives the radio quality measurement data generated when the mobile communication terminal 201 enters a traffic state by requesting a mobile communication service (for example, a voice call, an SMS, and a data call). Received from the location information is extracted and transmitted to the operation server 211. Since the mobile communication terminal 201 in a traffic state moves and performs frequent handovers or performs power control, the base station controller 205 uses the mobile communication terminal in the radio quality measurement data generated during the handover or power control. The location information of 201 is extracted and transmitted to the operation server 211.

The exchange / SGSN 207 provides an interface function with the base station controller 205, and exchanges between mobile communication subscribers and a mobile communication subscriber with a fixed network such as a PSTN, ISDN, and IP network (interworking function). do. In particular, the exchange / SGSN 207 may visit the home location register 209 or the visited location register (VLR) in the exchange / SGSN 207 when a location registration request for a specific mobile communication terminal 201 comes from the base station controller 205. Register in the: Visitors Location Register.

The operation server (O & M server) 211 manages a plurality of base station controllers 205 and receives and stores location information of the mobile communication terminal 201 from the base station controller 205. Such operation server 211 is preferably installed and installed in the exchange unit. In addition, the operation server 211 may set a subcell (MSC, BSC / RNC, BTS / NodeB, FA, etc.) to obtain the location information. The operation server 211 sets a subcell to obtain the location information and transmits the corresponding subcell information to the base station controller 205, and the base station controller 205 registers the location registration by the mobile communication terminal 201 in the subcell. When performing or in a traffic state, location information is extracted and transmitted to the operation server 211.

The data collection server 213 collects and stores location information of the mobile communication terminal 201 from a plurality of operation servers 211, and stores and integrates the location information of the stored mobile communication terminal 201 with the location management server 215. To send. The location management server 215 may provide various location based services using location information of the mobile communication terminal 201 collected from the data collection server 213. An embodiment of the location based service using the location information of the mobile communication terminal 201 stored in the location management server 215 will be described later.

Hereinafter, a method of obtaining location information of a mobile communication terminal in a location based service system according to the present invention described with reference to FIG. 2 will be described in detail with reference to the accompanying drawings.

3 is a flowchart illustrating a method of measuring a location of a mobile communication terminal according to an embodiment of the present invention, which is a method of measuring a location of a mobile communication terminal performing location registration.

As shown in FIG. 3, the mobile communication terminal 201 makes a location registration request to a base station system (BSS: base station system and base station controller) in order to register its location in a mobile communication network (S301).

In this way, the base station system that receives the location registration request from the mobile communication terminal 201, that is, the base station controller 205 requests the location registration of the mobile communication terminal 201 to the exchange or SGSN (207) (S303). In response to the location registration request from the base station system, the exchange or SGSN 207 requests the location registration of the mobile communication terminal 201 to the home location register 209 (S305). Of course, when the mobile communication terminal 201 requests location registration by movement within the exchange or SGSN 207 area, the exchange or SGSN 207 does not request a location registration to the home location register 209, Location registration can only be performed at the visited location register.

In this way, the switch or SGSN 207 that requests the location registration of the mobile communication terminal 201 to the home location register 209 receives a location registration response from the home location register 209 (S307), and thereby receives the location registration response. It transmits to the mobile communication terminal 201 via the base station system (S309, S311).

Meanwhile, in step S303, the base station system that receives the location registration request from the mobile communication terminal 201, that is, the base station controller 205 extracts the location information from the location registration request transmitted from the mobile communication terminal 201, thereby providing location information. The message is transmitted to the operation server 211 (S313). The operation server 211 receiving the location information message transmits the location information message to the data collection server 213, and the data collection server 213 transmits the location information message collected from the plurality of operation servers 211 in real time or in real time. It transmits to the location management server 215 every designated period.

As described with reference to FIG. 1, the mobile communication terminal performs location registration in various ways as follows. That is, in the case of a CDMA mobile communication system, registration when the power is turned on (Power-up Registration), registration when the power is turned off (Power-down Registration), and time-based registration for the terminal to be provided with the service normally (Distance-based Registration) that is performed when the terminal is out of a certain distance from the last registration point, Zone-based Registration, in which the terminal changes the location area and registers a new location area. Parameter-change registration, which is performed when a parameter such as a number is changed, the exchange recognizes that the terminal has changed its location area, but commands the terminal to request location registration because it lacks information for registering the location of the terminal. Order registration, the exchange changes the location area of the terminal through originating or incoming response If implicitly recognized that the location area of the terminal is changed by implicit registration to perform the location registration for the terminal, handoff in the call state, the exchange itself performs the location registration for the terminal There is a traffic channel registration. In the WCDMA mobile communication system, a location registration (Normal LU or RU) in which a terminal performs a location movement and registers as a new location, registration when the power is turned on (attach), registration when the power is turned off (Detach), and the terminal normally services There is a periodic registration (Periodic Lu or Ru) to receive.

An example of such a location registration is a standard location registration, non-standard location registration can be performed for a particular business. For example, a system and a terminal function may be implemented so that location registration may be performed at the time of entry / exit within a specific zone area for a private wireless network service. As a more specific example, when a location registration is performed when a specific bit of a base ID is changed in a CDMA mobile communication system (Reg Type = 12), a location is changed when a specific bit is changed in a cell ID in a WCDMA mobile communication system. When registering (Normal LU or RU).

As described above, location registration may be performed in a standard manner, or may be performed in a non-standard manner. The location service using the location registration is conventionally made through the home location register 209 and the visited location register. As described above, in the present invention, the location service is performed using the path of the base station controller 205 and the operation server 211. It is possible to reduce the load on the home location register 209 and the visited location register.

On the other hand, the mobile communication terminal 201 reports the wireless quality measurement to the mobile communication network for handover or power control when making a voice call, an SMS origination call, a data call, or the like. The radio quality measurement report includes location information of the mobile communication terminal 201, and accordingly, the present invention may provide location services by extracting location information from the radio quality measurement report.

4 is a flowchart illustrating a method of measuring a location of a mobile communication terminal according to another embodiment of the present invention, which is a method of measuring a location of a mobile communication terminal in a traffic state.

As shown in FIG. 4, the base station controller 205 requests the radio quality measurement report to the mobile communication terminal 201 in a traffic state through the base station 203 (S401). In the radio quality measurement report request, a CDMA system transmits a periodic pilot measurement report (PPMRO) message, and a WCDMA system transmits a measurement control (MC) message. In the radio quality measurement report, a radio quality measurement cycle is set. However, the present invention is not necessarily limited thereto, and radio quality measurement may be performed in an eventual manner. In this case, a CDMA system transmits a pilot measurement report order (PMRO) message, and a WCDMA system transmits a measurement control (MC) message without period information.

The mobile communication terminal 201 receiving the radio quality measurement report request periodically transmits a radio quality measurement result including radio quality information to the base station controller 205 (S403). As a result of radio quality measurement, a CDMA system transmits a periodic pilot strength measurement message (PPSMM) (PSMM in case of eventability), and a WCDMA system transmits a measurement report (MR) message.

On the other hand, the base station controller 205 requests the round trip delay time to the base station 203 to determine the round trip delay time between the base station 203 and the mobile communication terminal 201 (S405) and receives a response (S407). . In the CDMA system, the round trip delay time is a vendor implementation issue in which the protocol is not defined. In the present invention, the base station controller 205 requests a round trip delay (RTD) from the base station 203 and receives a response accordingly. The WCDMA system transmits a dedicated measurement initialization request message (DMIR) to the base station 203, receives a dedicated measurement report message (DMR), and receives a round trip time (RTT).

The base station controller 205, which has received the radio quality measurement result and the round trip delay time from the base station 203, extracts the location information from the radio quality measurement result, synthesizes the location information with the round trip delay time, and generates a location measurement message. The location measurement message is transmitted to the operation server 211 (S409). In case of CDMA system, it includes MSC, BSC, BTS, SEC, PN, RTD, PN Phase information as location information, and in case of WCDMA system, MSC, RNC, NodeB, SEC, PSC, RTT, Rx-Tx Time Difference Information, terminal latitude / longitude information.

The operation server 211 transmits the location measurement message received from the base station controller 205 to the data collection server 213 (S411), and the data collection server 213 collects the location information collected from the plurality of operation servers 211. The message is transmitted to the location management server 215 in real time or every designated period (S413).

By measuring the position of the mobile communication terminal 201 in the traffic state as described above, it is possible to distinguish the position of the mobile communication terminal 201 by the base station / sector even within the same location registration area. In general, location registration is managed on a per exchange basis or a paging zone basis. However, since one location registration area may include a plurality of base stations, when the radio quality measurement message of the mobile communication terminal 201 is in a traffic state as described above, the mobile communication terminal 201 is located in the location registration area. Know which base station / sector it is located in.

5 is a diagram illustrating a network configuration of a location based service system for obtaining location information of a mobile subscriber according to another embodiment of the present invention.

In FIG. 5, components having the same reference numerals as those of FIG. 1 perform the same functions, and detailed description thereof will be omitted. The location based service system shown in FIG. 5 further includes a billing processing device 501.

When the mobile communication terminal 201, which has been performing voice / video transmission or SMS transmission, terminates the call, the exchange / SGSN 207 generates charging data including the call start / end time of the mobile communication terminal 201, and the like. To the billing processing device 501, and the billing processing device 501 calculates the usage fee of the mobile subscriber based on the billing data transmitted from the exchange / SGSN 207. However, the charging data transmitted from the exchange / SGSN 207 to the charging processing device 501 includes base station information at the time when the mobile communication terminal 201 ends the call. Therefore, the location of the mobile communication terminal 201 can be determined using the charging data. The billing processing unit 501 transmits the billing data transmitted from the exchange / SGSN 207 to the location management server 215, and the location management server 215 reads out the location information from the billing data and stores and manages it.

6 is a flowchart illustrating a method for measuring a location of a mobile communication terminal according to another embodiment of the present invention, which is a method of measuring the location of a mobile communication terminal using charging data.

As shown in Fig. 6, when the mobile communication terminal 201 in the traffic state ends the call, the exchange / SGSN 207 generates charging data of the mobile communication terminal 201 (S601). In this case, the charging data includes base station information where the mobile communication terminal 201 was finally located at the end of the call.

The exchange / SGSN 207 which has generated the billing data in this way transmits the billing data to the billing processing device 501 (S603), and the billing processing device 501 calculates and calculates the subscriber's fee based on the billing data. However, the charging data is transmitted again to the location management server 215 (S605). The location management server 215 reads out and stores and manages the base station information where the mobile communication terminal 201 is located in the charging data.

As described above, the location information of the mobile communication terminal 201 is collected and the handover or power control of the mobile communication terminal 201 in a traffic state is collected through the base station controller 205. By doing so, it is possible to provide a location based service (LBS) such as friend search, emergency rescue, traffic information, and advertisement information service. Hereinafter, an embodiment of providing a corporate location service using location information of a mobile communication subscriber collected through the operation server 211 will be described with reference to the drawings. The corporate location service is a service that provides a specific service message (eg, an advertising message) to the corporate subscriber when the corporate subscriber is located in the area set by the corporation. There may be a number of legal entities, and each legal entity sets its own service area. Therefore, the service areas of each corporation may overlap.

7 is a diagram showing a network configuration of a corporate location service system according to an embodiment of the present invention.

As shown in FIG. 7, the corporate location service system according to the present invention includes a location management server 215, a corporate location service server 710, and an SMSC / MMSC 720. Here, the location management server 215 receives and stores the location information of the mobile communication terminal 201 collected by the operation server 211 from the data collection server 213 as described with reference to FIG. 2. In addition, the location management server 215 receives and stores the location information of the mobile communication terminal 201 from the charging processing device 501 as described with reference to FIG. 5. In addition, the location management server 215 may receive and manage corporate service subscriber information from the corporate location service server 710 and transmit the corporate service subscriber information to the corporate location service server 710 whenever there is a change in the location of the corporate service subscriber. To this end, the location management server 215 manages by placing an indicator (indicator) for the corporate service subscriber. In this case, the corporate location service server 710 may be independently implemented in the location management server 215, or may be integrally implemented in the location management server 215. Therefore, in the following claims, it should be understood that the location management server 215 may provide a location based service including a service server such as the corporate location service server 710 of the present embodiment.

The corporate location service server 710 receives the location information of the mobile communication terminal 201 from the location management server 215, and based on the received location information, which corporation is located where the mobile communication terminal 201 is located. (E.g., department store, discount mart, amusement park, etc.) The service message (for example, an advertisement message) set by the determined corporation is searched and transmitted to the mobile communication terminal 201. Therefore, the mobile communication subscriber may be provided with various service messages provided by the corporation to which the mobile subscriber is located in a specific region.

As shown in FIG. 7, the corporate location service server 710 includes a location information manager 711, a corporate inquiry unit 712, a service message transmitter 713, an entire corporate DB 714, and a plurality of individual individuals. Corporate databases 715 and 716 are included. A plurality of individual corporate DBs (715, 716) stores subscriber information (MIN, IMSI, etc.) to receive service messages provided by each corporation, and also service area information (Cell ID, Base ID, etc.) to provide service messages. Is stored, a service message (eg, a guide message, an advertisement message) to be actually provided to the subscriber is stored. In addition, control information to be provided with the service message, for example, time information and the number of transmissions are stored. In addition, the service grade of the subscriber and service messages for each service grade are stored separately. In this case, a message transmission identifier may be added to the subscriber information to prevent duplicate transmission of the service message. The whole corporation DB 714 integrates and manages subscriber information stored in the plurality of whole corporation DBs 715 and 716.

The location information manager 711 manages the location information of the mobile communication subscriber who subscribed to the corporate service in association with the location management server 215. That is, the location information manager 711 requests the location management server 215 for location information on the mobile communication subscriber stored in the entire corporation DB 714 and receives the location information accordingly. Alternatively, the location management server 215 may transmit the location information of the subscriber to the location information management unit 711 whenever there is a location change for the subscriber having the corporate service indicator.

The corporation inquiry unit 712 inquires on which corporation's service area the mobile communication terminal 201 is located based on the location information of the mobile communication terminal 201 received by the location information management unit 711. That is, the corporation inquiry unit 712 searches for each individual corporation DB 715 and 716 and selects a corporation that stores location information corresponding to the location information (for example, base station information or subcell information) of the mobile communication terminal 201. Inquire.

As such, when the corporation in which the mobile communication terminal 201 is located is inquired by the corporation inquiry unit 712, the service message transmission unit 713 transmits a service message (eg, an advertisement) from the individual corporation DBs 715 and 716 of the corporation. Message) to be transmitted to the mobile communication terminal 201 through the SMSC / MMSC 720 of the mobile communication network. At this time, the service message transmitter 713 transmits the service message based on the control information stored in the individual corporation DBs 715 and 716. For example, when a specific time zone is set as a message transmission prohibition time zone, the service message transmitter 713 determines whether the current time is the specific time zone and does not transmit a service message when the current time is the specific time zone. In addition, the service message transmitter 713 transmits a service message according to the service level of the subscriber.

If the area in which the mobile communication terminal 201 is located is a common area of a plurality of corporations, a plurality of corporations are inquired by the corporation inquiry unit 712, and the service message transmitter 713 sends a plurality of service messages. Is transmitted to the mobile communication terminal 201.

Meanwhile, in the embodiment referring to FIG. 6, when the mobile communication subscriber is located in a specific area, the service message of a corporation that sets the corresponding area as a service area is transmitted to the mobile communication subscriber. However, the embodiment in which a specific person joins the corporate service in the corporation and controls access is also possible. That is, an embodiment in which an internal employee is subscribed to a corporate service and an internal employee enters and exits a specific area to notify the corporate operator of the fact that the internal employee has entered. In this case, the service message transmission unit 713 transmits a message about the fact of entry to the corporate operator or the corporate system, not the internal staff.

8 is a flowchart illustrating a corporate location service method according to an embodiment of the present invention.

As shown in FIG. 8, the location management server 215 transfers the location information of the subscriber to the corporate location service server 710 when the subscriber having the corporate service indicator has a change in location (such as location registration). Transmit (S801, S803). Alternatively, according to an embodiment, the corporate location service server 710 requests the location management server 215 for location information about all subscribers stored in the entire corporate DB 714, and the location management server 215 responds to the entire subscribers. Location information may be transmitted to the corporate location service server 710.

Next, the corporate location service server 710 compares the location information of each subscriber transmitted from the location management server 215 with the service area information stored in each individual corporate DB 715 and 716, so that each subscriber of the corporation Search whether the service area is located (S805).

After searching for a corporation in this way, the corporate location service server 710 verifies whether the subscriber is a subscriber of the found corporation (S807). This is done through individual corporate databases 715 and 716. Since each individual corporation DB (715, 716) stores and manages the subscriber information of each corporation, the corporate location service server 710 compares the subscriber information to verify whether the subscriber located in the corporate service area is a subscriber of the corporation.

If the subscriber is a subscriber of the corporation, the corporate location service server 710 queries the individual corporation DB (715, 716) of the corporation to select a service message (S809). The corporate location service server 710 transmits the selected service message to the subscriber through the SMSC / MMSC 620 (S811). At this time, the corporate location service server 710 transmits the service message based on the control information stored in the individual corporate DBs 715 and 716. For example, when a specific time zone is set as a message transmission prohibition time zone, it is determined whether the current time is the specific time zone and the service message is not transmitted when the current time is the specific time zone. In addition, different service messages may be selected and transmitted according to the service level of the subscriber.

Meanwhile, in the embodiment referring to FIG. 8, when a mobile communication subscriber is located in a specific area, the service message of a corporation that sets the corresponding area as a service area is transmitted to the mobile communication subscriber. However, the embodiment in which a specific person joins the corporate service in the corporation and controls access is also possible. That is, an embodiment in which an internal employee is subscribed to a corporate service and an internal employee enters or exits a specific area is notified to the corporate operator or the system. In this case, in step S809, the corporate location service server 710 searches for an access fact notification message and transmits the access fact notification message to a corporate operator or a corporate system other than an internal employee.
