Hereinafter, as an example, a method of providing location information of a terminal and a method of providing location based service using location information of a terminal in a portable internet system based on the NWG standard standard will be described.

In the method of providing location information of the terminal and the method of providing location-based services using the location information of the terminal, it is assumed that the location information of the terminal is recognized by an access service network (ASN) or a connectivity services network (CSN). Here, the method of obtaining location information of a terminal may include adding a device capable of tracking a location such as a global positioning system (GPS), generating a specific signal in a terminal, using a channel provided separately between the terminal and the base station, The triangular measurement method of the base station may be applied, and the present invention does not describe the method for obtaining location information.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram showing the configuration of a portable internet system, and FIG. 2 is a diagram showing the configuration of an access service network (ASN) of the portable internet system. In FIG. 1, R3 and R4 represent interfaces between respective network members.

1 and 2, a portable Internet system may include an access services network (hereinafter referred to as an 'ASN'), a visiting connectivity services network (hereinafter referred to as a 'V-CSN'), and a portable Internet system. , Home Connectivity Services Network (hereinafter referred to as "H-CSN"), Service Provider (Application Service Provider, referred to as "ASP"), Home IP Network (not shown) It includes a plurality of terminals (Mobile Station).

ASN provides radio service infrastructure to network service providers, and is called base station (BS), access control router (ACR), and ASN gateway (ASN-GW). ).

When the MS starts a service by first entering the network (network entry), as shown in FIG. 2, the Authenticator ACR, the Anchor ACR, and the Serving ACR are present in the same ASN.

The terminal should always be able to receive service at all times with IP. Therefore, once connected to the network, it must remain connected to the network except in special cases. Since the portable Internet system supports the mobility of the terminal, the ACR where the terminal is initially connected may be different.

Anchor ACR is a part where traffic data is transmitted by being connected to a home IP network, and also where data of a terminal passes. To this end, the Anchor ACR includes an Anchor DPF and designates a data path of data transmitted in the IP network. The Anchor ACR is directly connected to the IP network, and data is transmitted and received to the Serving ACR in which the actual terminal is located via the Anchor ACR.

Serving ACR is a place where an actual terminal is connected and includes a Serving DPF. Data transmitted to the Anchor ACR is transmitted to the terminal via the Serving ACR. In addition, the Serving ACR designates a path in which the Serving DPF moves to the base station BS. Data traffic occurs through the designated path.

The Authenticator ACR is responsible for accounting and authentication where the terminal is initially connected, and generates additional service flows. In addition, the Authenticator ACR includes an anchor SFA that performs authentication for a newly added service flow.

It may be configured in an Authenticator ACR, Anchor ACR, or Serving ACR of an Anchor PC (Paging Controller, LR: Location Register).

V-CSN and H-CSN provide subscribers with IP connectivity and network services. Location Server (LS) and Authorization, Authentication and Accounting (AAA) Server), PDF (Policy Distribution Function) and PCRF (Policy Control and Charging Rules Function).

PCEF acts as an interface between the home IP network and PDF / PCRF and provides information about Radio QoS Policy to Anchor SFA.

The AAA server configured in the H-CSN uses the information on the ASN to be initially connected when the terminal enters an area where the location-based service is provided. Receive information about Anchor Authenticator.

When the terminal enters the network, the location information of the terminal is generated through the connected ASN, the location information of the terminal is stored in the AAA server and provided to the service provider (ASP).

The ASP detects the location of the terminal using the received location information of the terminal, and if the terminal is located in a specific region, the ASP provides a service that can be provided in the specific region, that is, a location-based service. To this end, the ASP includes a content server storing content of a location-based service, and a service subscription information server storing location-based service subscription information of all terminals subscribed to the portable Internet system.

When the ASP recognizes that the terminal is located in an area where the location-based service can be provided using the location information of the terminal, the ASP determines whether the terminal subscribes to the location-based service using the service subscription information stored in the service subscription information server. . Thereafter, according to the result of confirming whether to subscribe to the location-based service, the terminal provides content of the service to the terminal.

As described above, in order for the ASP to provide a location-based service to a terminal located in a specific region, the ASP must be provided with location information of the terminal. In addition, the service flow and the data path according to the location-based service should be set between components of the portable Internet system so that location-based service can be provided to the terminal by using the received location information of the terminal.

In the present invention according to the embodiment, the location information of the terminal is transmitted to the H-PCRF via the V-PCRF in the Anchor SFA / PCEF of the ASN. In this case, the V-PCRF and the H-PCRF transmit the location information of the terminal transmitted from the Anchor SFA / PCEF of the ASN to the ASP to generate a service flow for providing the location-based service to the terminal. Here, the ASP has location-based service subscription information of all terminals subscribed in the portable Internet system.

In this case, the generation of the service flow is determined by the AF of the ASP, and the service flow is determined based on the location-based service subscription information of the terminal located in the specific region together with the terminal location information. If a service flow creation decision is made in the AF of the ASP, the AF of the ASP sends a service flow creation command to the H-CSN. Through the service flow generation command, service flow generation of a location-based service to be provided to a terminal located in a specific region between ASN, V-CSN, H-CSN and ASP is made.

Here, the terminal may be in an active mode, an idle mode, or a network entry state. Therefore, the method of providing the location information of the terminal and the method of providing the location-based service using the location information of the terminal according to the state of the terminal can be provided regardless of the state of the terminal.

According to an embodiment of the present invention, a method of providing location information of a terminal according to an active mode, an idle mode, or a network entry state, and a method of providing location-based services using the location information of the terminal By providing a, it is possible to provide a location-based service regardless of the state of the terminal.

Hereinafter, a method of providing location information of a terminal and a method of providing location-based service using location information of a terminal will be described with reference to FIGS. 3 to 11.

3 is a diagram illustrating a method for providing location information of a terminal entering an idle mode.

Referring to FIG. 3, when an entry into an idle mode is determined for an active mode terminal by a request from a terminal or a determination of a serving base station, a serving BS sends an IM_Entry_State_Chang_Req message requesting entry of an idle mode by the terminal. To transmit to the ACR (S110).

Thereafter, the ACR transmits an IM_Entry_State_Chang_Req message from the serving BS to the Anchor PC (S112). Thereafter, the Anchor PC sends an IM_Entry_State_Chang_Req message from the control station ACR to the Authenticator ACR (S114).

After receiving the IM_Entry_State_Chang_Req message, the Authenticator ACR approves entering the idle mode of the terminal and transmits an IM_Entry_State_Chang_Rsp message to the Anchor PC in response (S116). Thereafter, the Anchor PC transmits an IM_Entry_State_Chang_Rsp message from the Authenticator ACR to the ACR (S118).

Thereafter, the ACR transmits an IM_Entry_State_Chang_Rsp message to the serving base station in response to the idle mode entry request of the terminal received from the serving base station in S110 (S120).

The serving base station receiving the IM_Entry_State_Chang_Rsp message from the ACR sends a IM_Entry_State_Chang_Ack message to the ACR in response (S122).

Thereafter, the ACR transmits an IM_Entry_State_Chang_Ack message from the serving base station to the Anchor PC (S124). Thereafter, the Anchor PC sends an IM_Entry_State_Chang_Ack message from the ACR to the Authenticator ACR (S126).

In addition, the Anchor PC sends an Anchor_PC_Ind message to the Anchor DPF to inform that the terminal has entered the idle mode (S128). Thereafter, the Anchor DPF transmits the Anchor_PC_Ack message to the Anchor PC in response to the received Anchor_PC_Ind message (S130).

Thereafter, when the Anchor DPF recognizes the terminal entering the idle mode, a procedure of releasing the data path established between the Anchor DPF and the serving BS is performed (S132). Thereafter, the Anchor DPF transmits a Context_Rpt message to the Authenticator ACR and grants an authentication key (S134).

Thereafter, the Authenticator ACR sends the Location_Rpt message to the PDF and PCRF of the CSN to inform the terminal of the location information, and the PDF and PCRF of the CSN receiving the Location_Rpt message from the Authenticator ACR transmits the Location_Ack message in response thereto (S136). ). Thereafter, by receiving the Location_Rpt message, the PCRF of the CSN recognizing the location information of the terminal transmits the recognized location information of the terminal to the AF of the ASP. Through the above-described procedures, the location information of the terminal entering the idle mode may be transmitted to the CSN and the ASP.

4 is a diagram illustrating a method of providing location information of an idle mode terminal.

Referring to FIG. 4, when the MS in the idle mode moves and enters the location-based service area, ranging should be performed. Accordingly, the terminal requests ranging by transmitting an RNG-REQ message to the serving base station (S210).

Thereafter, the serving base station notifies the ranging request of the terminal by transmitting a UL-Req message to the ASN-GW (S212). Thereafter, the ASN-GW notifies the ranging request of the terminal by transmitting the UL-Req message received from the serving base station to the Anchor PC (S214).

Thereafter, the Anchor PC recognizes the ranging request of the terminal through a UL-Req message, and then sends an Context_Req message to the Authenticator ACR to request an authentication key (S216).

Thereafter, the Authenticator ACR transmits the Context_Rpt message to the Anchor PC in response to the Context_Req message to the Authenticator ACR received from the Anchor PC and grants an authentication key (S218).

Thereafter, the Anchor PC transmits a UL-Rsp message in response to the UL-Req message received from the ASN-GW (S220). Thereafter, the ASN-GW transmits a UL-Rsp message in response to the UL-Req message received from the serving base station (S222).

When the serving base station receives the UL-Rsp message from the ASN-GW, the serving base station transmits an RNG-RSP message in response to the RNG-REQ message received from the terminal to approve the ranging request of the terminal (S224).

Thereafter, the serving base station transmits a CMAC_Key_Count_Update message to the ASN-GW in order to update the Cipher-base Message Authentication Code (CMAC) key count value (S226). Thereafter, the ASN-GW transmits the CMAC_Key_Count_Update message received from the serving base station to the Authenticator ACR (S228).

Thereafter, the Authenticator ACR transmits a CMAC_Key_Count_Update_Ack message to the ASN-GW in response to the received CMAC_Key_Count_Update message (S330). Thereafter, the ASN-GW receiving the CMAC_Key_Count_Update_Ack message from the Authenticator ACR transmits a CMAC_Key_Count_Update_Ack message to the serving base station (S332).

Thereafter, the serving base station transmits a UL_Cnf message to the ASN-GW to inform the user of the ranging and update of the CMAC key count value (S234). Thereafter, the ASN-GW transmits a UL_Cnf message received from the serving base station to the Anchor PC to inform the ranging and update of the CMAC key count value of the terminal (S236).

Thereafter, the Anchor PC transmits a Location Update message or a Context_Rpt message to the Authenticator ASN to inform the terminal of the location information (S338).

Thereafter, the Authenticator ASN sends the Location_Rpt message to the PDF and PCRF of the CSN to inform the location information of the terminal, and the PDF and PCRF of the CSN receiving the Location_Rpt message from the Authenticator ASN transmits the Location_Ack message in response (S340). ).

Thereafter, by receiving the Location_Rpt message, the PCRF of the CSN recognizing the location information of the terminal transmits the recognized location information of the terminal to the AF of the ASP. Through the above-described procedures, the location information of the idle mode terminal can be transmitted to the CSN and the ASP.

5 is a diagram illustrating a method of providing an entry into an idle mode and providing location information of a terminal in an idle mode.

Referring to FIG. 5, when the entry into the idle mode is determined for the active mode terminal by the request from the terminal MS or the determination of the serving base station, between the serving BS and the terminal, the serving base station, and the ASN. An idle mode entry procedure is performed (S310).

When the idle mode procedure of the terminal is performed, the Authenticator ASN transmits a Location Report message to the PDF / PCRF of the CSN, and informs the CSN of the location information of the terminal entering the idle mode (S312).

Thereafter, the CSN transmits a Location Ack message to the Authenticator ASN in response to the Location Report message received from the Authenticator ASN (S314). Thereafter, the PCRF of the CSN transmits a Notify_location_report message to the AF of the ASP to inform the ASP of the terminal location information (S316). Through the above-described S310 to S316 procedures, location information of the terminal entering the idle mode may be informed to the CSN and the ASP.

Thereafter, the ASP that receives the location information of the terminal from the Authenticator ASN updates the location information of the received terminal (S318). Then, when the state of the terminal is changed from the idle mode to the active mode, the ASP may provide a location-based service to the terminal based on the location information of the terminal.

On the other hand, when the MS in the idle mode moves to enter the location-based service area, a ranging procedure is performed between the serving BS, the terminal, the serving base station, and the ASN, and then the update procedure of the location information of the terminal is performed. (Location Update Procedure) is performed (S320).

Thereafter, the Authenticator ASN transmits a Location Report message to the PDF / PCRF of the CSN, and informs the CSN of the location information of the terminal (S322).

Thereafter, in response to the Location Report message received from the Authenticator ASN, the CSN transmits a Location Ack message to the Authenticator ASN (S324). Thereafter, the PCRF of the CSN transmits a Notify_location_report message to the AF of the ASP, and informs the ASP of the location information of the terminal (S326). Through the above-described S320 to S326 procedures, location information of the idle mode terminal may be informed to the CSN and the ASP.

Thereafter, the ASP that receives the location information of the terminal from the Authenticator ASN updates the location information of the received terminal. After checking whether the terminal subscribes to the location-based service, the terminal may provide the location-based service to the terminal based on the location information of the terminal according to the result of confirming the subscription of the location-based service.

6 is a diagram illustrating a location information providing method and a location based service providing method of an active mode terminal.

Referring to FIG. 6, an active terminal may move and enter a location based service area, which is the same as that of a serving base station providing a service to the terminal.

Therefore, since the terminal should handover by selecting a target base station (Target BS) from the adjacent base stations, and transmits the MOB_MSHO-REQ message including the information (NBR RAS List) of the neighbor base stations to the serving Anchor ASN (S410) . Subsequently, a Context Retrieval procedure is performed between the serving Anchor ASN and the Authenticator ASN to transmit and receive a Context_Req message and a Context_Rsp message, thereby obtaining an authentication key (S412).

In addition, the serving anchor receiving the MOB_MSHO-REQ message from the terminal determines a target base station among neighbor base stations and transmits a HO_Req message to a target ASN through a backbone network (S414).

In addition, the serving anchor sends a Path_Prereg_Req message to the target ASN to request data path reservation (S416).

Thereafter, the target ASN transmits a HO_Rsp message to the serving anchor in response to the HO_Req message received from the serving anchor (S418).

The target ASN, which has received the Path_Prereg_Req message from the serving anchor, transmits a Path_Prereg_Rsp message in response to this, and responds to the data path reservation request (S420). Thereafter, the serving Anchor receiving the Path_Prereg_Rsp message from the target ASN transmits a Path_Prereg_Ack message to the target ASN and informs that the Path_Prereg_Rsp message has been received (S422).

Thereafter, the serving anchor transmits the MOB_MSHO-RSP message to the terminal in response to the MOB_MSHO-REQ message received in S410 (S424). Here, the MOB_MSHO-RSP message transmitted to the terminal includes an action time, information on a candidate base station suitable as a target base station among adjacent base stations, and a handover ID (HO ID).

Thereafter, the serving anchor transmits a HO_Ack message to the ASN to inform that the terminal has handed over to the target base station (S426).

Thereafter, the terminal transmits a MOB_HO-IND message including information on the target BS, a handover mode, and a handover type to the serving anchor (S428).

Subsequently, the serving ASN transmits a HO_Cnf message including BS Switching Timer information required for changing the base station of the UE to the target ASN (S430). Here, the HO_Cnf message includes time information when the serving base station transmits the HO_Cnf message.

Thereafter, the target ASN transmits a HO_Ack message in response to the HO_Cnf message received from the serving ASN (S432). Thereafter, a data path reservation procedure is performed between the serving ASN and the target ASN (S434).

Thereafter, a network reentry procedure is performed between the UE and the Authenticator ASN (S436). Thereafter, a Path_Reg_Req message and a Path_Reg_Rsp message are transmitted and received between the serving ASN and the target ASN to form a data path (S438).

 In addition, the CMAC_Key_Count_Update message and the CMAC_Key_Count_Update_Ack message are transmitted and received between the target ASN and the Authenticator ASN to update the CMAC key count value (S440).

Through the above-described process, the terminal completes the handover to the target ASN, and accordingly, the Authenticator ASN transmits a HO_Complete message to the serving ASN to inform the terminal of the handover completion (S442). Thereafter, the serving ASN transmits the received HO_Complete message to the target ASN to notify the handover completion of the terminal (S444).

Subsequently, the serving ASN performs a data path release procedure configured for the terminal (S446), and the target ASN transmits a Context_Rpt message to the Authenticator ASN to inform the terminal of handover completion and handover location information. (S448).

Through the above-described S410 to S448 procedures, location information of the active mode terminal may be informed to the CSN and the ASP.

Thereafter, the Authenticator ASN requests a location-based service by transmitting a Service Location_Req message to the PDF / PCRF of the CSN, and the ASN receiving the Service Location_Req message transmits a Service Location_Ack message to the Authenticator ASN in response (S450).

Thereafter, the CSN requests a location-based service for the terminal handed over to the AF of the ASP, and creates a session for providing the location-based service between the AF and the terminal of the ASP according to the request for the location-based service (S452). ). Through the above-described procedures, the location-based service can be provided to the terminal using a session created between the terminal and the AF of the ASP.

7 is a diagram illustrating a service flow generation method and a service providing method for providing a location-based service. The service flow generating method and the service providing method illustrated in FIG. 7 are applied when the terminal is in an active mode.

Referring to FIG. 7, when the terminal accesses an IP network through a serving ASN and moves to a location-based service area while receiving an IP and multimedia service, as shown in S510, between the terminal and the Authenticator ASN. A handover procedure is performed to hand over to a base station that provides location-based services (S512).

Thereafter, an Authenticator ASN Service_location_Req message is transmitted to the CSN to request location information of the handovered terminal and a location-based service that can be provided by the terminal (S514).

Thereafter, the CSN notifies the location information of the terminal by transmitting a Notify_location_report message to the AF of the ASP (S516). Thereafter, the CSN transmits a Service_location_Rsp message to the Authenticator ASN in response to the Service_location_Req message received from the Authenticator ASN in S514 (S518).

Thereafter, the ASP determines whether the terminal is located in a location of providing a location-based service based on the received location information of the terminal (S520), and if the terminal is located in a location-based service area, the ASP for location-based service between the terminal and the terminal is located. Create a session (S522). Through the above-described procedures, a multimedia service is provided to the terminal using a session created between the terminal and the AF of the ASP (S524).

On the other hand, when the terminal is not in the active mode, that is, when the data or service transmitted to the terminal is provided when the terminal is in the idle mode, the terminal after paging the idle mode terminal through the procedure shown in FIG. To provide services.

Referring to FIG. 8, when the idle mode terminal moves to enter a location-based service area, or when data transmitted from the HA to the idle terminal is generated (S610), the serving ASN-GW is the idle mode, so that the terminal is idle. The data packet to be transmitted to the terminal is buffered until it is paged in the mode (S612).

Thereafter, the serving ASN-GW transmits an initial paging request (Initiate_Paging_Req) message to the Anchor PC / LR of the ASN in order to page the idle mode terminal (S614).

The Anchor PC / LR of the ASN transmits an initial paging response (Initiate_Paging_Rsp) message to the serving ASN-GW in response to the received initial paging request (Initiate_Paging_Req) message (S616).

Thereafter, the Anchor PC / LR of the ASN transmits an Initiate Announce message to the serving base station (BS) to indicate paging of the terminal (S618). Thereafter, the serving base station (BS) transmits a MOB_PAG-ADV message to the terminal to page the terminal in the idle mode (S620).

Thereafter, the terminal receiving the MOB_PAG-ADV message from the serving base station is paged from the idle mode to the active mode, and the location information of the terminal paged to the active mode is updated (S622). Thereafter, the buffered data packet is transmitted in S612 to provide a data service to the UE (S624).

The procedures of S610 to S624 described above may be equally applied to a case where a terminal enters a location based service area and data to be transmitted to the terminal is generated from an ASP.

9 is a diagram illustrating a method of providing service content through service flow generation.

Referring to FIG. 9, when service provision is generated for a terminal located in a location-based service area from an ASP, the ASP / AF informs the PDF / PCRF of the CSN that data to be transmitted to the terminal has been generated (S710).

Thereafter, the PDF / PCRF of the CSN transmits a service flow create request message to the ACR and requests creation of a service flow so that a location-based service can be provided to the terminal MS (S712).

Thereafter, the ACR transmits a Path_Reg_Req message to a service flow manager (hereinafter referred to as "SFM") of the base station and requests a data path generation for providing a location-based service (S714).

Thereafter, the SFM transmits a DSA-REQ message to the terminal and requests a dynamic service addition for providing a location-based service (S716). Thereafter, the UE transmits the DSA-RSP message to the SFM in response to the received DSA-REQ message to inform that the dynamic service has been added (S718).
