The access network includes a plurality of radio access devices (100). Here, the wireless access point 100 acts as a base station or an access point that performs wireless data transmission / reception through a channel connected to the user device 10 after connecting the wireless channel, for example, (Base Station), a Base Transceiver Station (BTS), a Node B, an eNode B, and the like, and a wireless access pointer of a Wi-Fi network.

That is, the wireless access point 100 can be implemented in a BTS (Base Station Transmission System) in a synchronous (CDMA) network, and a base station controller (BSC) Lt; / RTI > In addition, it can be implemented as a NodeB and an RNC (Radio Network Controller) in an asynchronous (WCDMA) network and as an eNodeB as an evolved base station in an LTE (Long Term Evolution) network. In addition, the eNodeB can support only 3.9 generation mobile communication standard or up to LTE-A, the fourth generation mobile communication standard.

These wireless access points 100 are distributed at different positions, have a communication coverage of a predetermined range, and form a wireless communication channel for use of the communication service of the user apparatus 10 entering the communication coverage. Specifically, the wireless access device 100 transmits a connection request from the user device 10 that has entered the communication coverage to the mobility management device 200, and transmits the access request from the user device 10 10).

Also, in the present invention, the wireless access device 100 may be a device supporting a specific mobile communication service (for example, an LTE-A mobile communication service) among two or more different mobile communication services provided by the mobile communication system, And non-supported devices. For example, while a plurality of radio access devices 100 provided in a mobile communication system to which the present invention is applied provide an LTE service, at least one of the plurality of radio access devices 100 may be an LTE-A mobile communication service, To selectively provide Carrier Aggregation or CoMP to a particular user device 10.

In addition, the above-described devices may be implemented as one server device or as a different device.

Among the components of the core network, the mobility management apparatus 200 is a functional element for managing the movement of the user equipment 10, for example, a concept including a Mobility Management Entity (MME) defined in the 3GPP standard. Specifically, the mobility management apparatus 200 enters a communication coverage of an arbitrary wireless access apparatus 100 and performs a location registration procedure for the user apparatus 10 requesting connection. In addition, the mobility management apparatus 200 can manage the idle mode user equipment 10 and select the serving gateway 300 and the PDN gateway 400 to manage the user equipment 10 . The mobility management apparatus 200 may also perform functions related to roaming and authentication with respect to the user equipment 10. [ In addition, the mobility management apparatus 200 can process the bearer signal generated by the user apparatus 10. [ Here, the message transmitted for the connection process in the non-connected state between the mobility management apparatus 200 and the user apparatus 10 is referred to as a NAS (Non Access Stratum) message. The NAS is an end-to-end protocol between the user equipment 10 and the core network, in particular, the mobility management apparatus 200, and is used for network connection management, authentication, call processing for establishing a bearer, session management,

At this time, the mobility management apparatus 200 supports a plurality of TAIs (Tracking Area Identity), and is connected to a plurality of wireless access points 100 that individually support TAIs. Accordingly, a plurality of wireless access points 100 supporting the same TAI have a connection with the same mobility management apparatus 200, and the wireless access points 100 supporting different TAIs are connected to other mobility management apparatuses 200 There is a possibility that you have.

The serving gateway 300 may serve as a mobile anchor when handing over between the wireless access points 100 of the user equipment 10 or between networks. In particular, in the LTE network, the serving gateway 300 can serve as a mobility anchor when the user equipment 10 performs handover and as a mobility anchor when moving the 3GPP radio network.

The PDN gateway 400 allocates an IP (Internet Protocol) address of the user equipment 10. The PDN gateway 400 acts as a mobile anchor when moving between different types of networks (for example, a 3GPP wireless network and a non-3GPP wireless network). In addition, the PDN gateway 400 determines the bearer band to provide to the user equipment 10. [ In addition, the PDN gateway 400 performs forwarding and routing functions for packet data.

In particular, the subscriber information management device 500 stores service subscription information for each user device 10 and provides the service subscription information to the mobility management device 200. The service subscription information includes not only supplementary service subscription information but also subscription information for any mobile communication service based on different mobile communication standards provided in the mobile communication system. In addition, the subscriber information management device 500 registers and updates the mobility information of the user device 10 in accordance with the location registration / update request from the mobility management device 200. [

Finally, the subscriber policy management apparatus 600 manages QoS and charging rules for each subscriber, and provides it to the PDN gateway 400 to perform QoS adjustment between the core network and the external network (packet data network). The subscriber policy management apparatus 600 may be a Policy and Charging Rules Function (PCRF) defined in 3GPP.

The user equipment 10 can use the data transmission path via the PDSN 400 and the PDSN gateway 400 to access the IMS network and the Internet network And connects to an external packet data network (PDN). To this end, when the user device 10 becomes able to communicate with the specific wireless access device 100 selected through the search procedure in accordance with the wireless link synchronization, the mobility management device 200 transmits the NAS Request (NAS Request) message. The NAS request message may be an Attach Request message, a Tracking Area Update Request message, or a Service Request message, for example.

In response to the request, the subscriber identification, the authentication and security procedure for the user equipment 10, the location registration procedure, and the session creation procedure are sequentially performed through the mobility management apparatus 200, A data transmission path is established via the PDN gateway 100, the serving gateway 300, and the PDN gateway 400, and then a call service or a data service is performed through the data transmission path.

However, if the user equipment 10 has a function to support a specific mobile communication service (for example, LTE-A) and is subscribed to the mobile communication service, The system should be able to provide the LTE-A mobile communication service when the user equipment 10 enters the communication coverage of the wireless access device 100 providing the LTE-A mobile communication service.

When the mobile communication apparatus 100 supports the specific mobile communication service, the wireless access apparatus 100 transmits the terminal capability information collected from the user apparatus 10 and the specific mobile communication service provided from the mobility management apparatus 200 And selectively activates a function corresponding to the specific mobile communication service. More specifically, the wireless access device 100 confirms from the terminal capability information collected from the user device 10 whether the user device 10 supports a specific mobile communication service function, When information indicating that the user equipment 10 is subscribed to a specific mobile communication service is transmitted from the mobility management apparatus 200 while supporting communication service, the specific mobile communication service function, for example, the carrier aggregation function is activated The radio resources of the user equipment 10 can be allocated.

2, the mobility management apparatus 200 may include a first communication interface unit 210, a second communication interface unit 220, a storage unit 230, and a control unit 240 .

The first communication interface unit 210 is a means for communicating with the radio access device 100. According to the proposal of the 3GPP, the first communication interface unit 210 can transmit a control message to the radio access device 100 through the S1-AP interface And processes the NAS signaling with the user device 10 through the wireless access device 100. [

For example, according to the proposal of the 3GPP, the subscriber information management apparatus 500 and a control message for providing user authentication, location registration / renewal, and roaming functions.

The storage unit 230 stores data necessary for the operation of the mobility management apparatus 200. In particular, the storage unit 230 stores the data of the users of the user devices 10 connected to the wireless connection apparatus 100 connected to the mobility management apparatus 200 Context (UE Context) is stored. The user context may include security context, roaming restriction information, performance information of the UE, S1 signaling connection ID, bearer setup information, and the like, as state information related to the network connection of the UE 10. Particularly, in the present invention, the user context stored in the storage unit 230 may include subscription information of a specific mobile communication service of the user device 10. [

The control unit 240 is a means for performing and controlling the overall operation of the mobility management apparatus 200 in cooperation with the first and second communication interface units 210 and 220 and the storage unit 230.

Specifically, the control unit 240 controls the functions of the above-described mobility management apparatus 200, the location registration / update for the user apparatus 10, the management of the user apparatus 10 in the idle mode, Selection of the serving gateway 300 and the PDN gateway 400 to manage the PDA 10 and roaming and authentication related to the user equipment 10.

In particular, in the present invention, the control unit 240 manages a user context for supporting a specific mobile communication service. The control unit 240 determines whether the subscriber profile information received from the subscriber information management apparatus 500 through the second communication interface unit 220 is registered in the subscriber profile information, And stores the information in the storage unit 230 in the user context. In addition, the control unit 240 controls the wireless access apparatus 100 in the communication coverage area in which the user apparatus 10 has entered to transmit the specific mobile communication service subscription information.

More specifically, after completing the location registration / update of the user equipment 10, the control unit 240 transmits the initial context information for the user equipment 10 to the radio access device 100 to which the user equipment 10 has entered, Upon the setup request, the specific mobile communication service subscription information may be recorded and transmitted in a specific field of a SPID (Subscription Profile ID for RAT / Frequency Selection) included in the initial context setup request.

Accordingly, the radio access device 100 receives the specific mobile communication service subscription information from the mobility management apparatus 200 before the allocation of the radio resources, and selectively transmits to the user device 10 radio Resource allocation can be performed.

FIG. 3 is a flowchart illustrating a method of managing a user context by the mobility management apparatus 200 having the above-described configuration. The user context management process by the mobility management apparatus 200 according to the present invention will be described in more detail with reference to FIG.

3, when the first location registration is requested from the user device 10 (S110), the mobility management device 200 receives from the subscriber information management device 500 a subscriber profile corresponding to the user device 10 Information is received (S120). Here, the mobility management apparatus 200 receives a connection request from the user apparatus 10 through the arbitrary wireless connection apparatus 100, and the user context, which is connection related information for the user apparatus 10, , It is determined that the registration is the initial location registration for the user device 10. [ However, the user context for the user device 10 may be stored in a mobility management apparatus different from the mobility management apparatus 200. [ For example, when the user equipment 10 moves from Seoul to Busan through a moving means such as an airplane or a train, and requests a connection through a wireless access device located in Busan, the mobility management device connected to the wireless access device transmits, Other mobility management devices that are not storing the user context for the device 10 but are connected to the wireless access device that has connected to the Seoul area may be storing the user context.

In step S120, the mobility management apparatus 200 transmits a location update request (Update Location request) to the subscriber information management apparatus 500 to the user apparatus 10 And transmits subscriber profile information related to the user device 10 via a location update response (Update Location Ack) transmitted from the subscriber information management device 500 that updates the location information of the user device 10 can do.

As described above, the mobility management device 200 receiving the subscriber profile information for the user device 10 confirms the specific mobile communication service subscription information from the service subscription information included in the subscriber profile information, and stores it in the user context And stores it in the storage unit 240 (S130). The user context is information related to the network connection of the user device 10 for maintaining the connection state of the user device 10 and includes security context, roaming restriction information, performance information of the user device 10, S1 signaling connection ID, Bearer setting information, and the like.

In addition, the mobility management apparatus 200 provides subscription information of the specific mobile communication service to the radio access apparatus 100 of the communication coverage in which the user apparatus 10 enters (S140). The subscription information of the specific mobile communication service is preferably performed before radio resource allocation between the radio access station 100 and the user equipment 10 is performed. For this, the mobility management apparatus 200 may transmit the specific mobile communication service subscription information together with an initial context setup request to the wireless access apparatus 100. [ Accordingly, the wireless access device 100 can allocate wireless resources and set up a wireless channel by applying the technology of a specific mobile communication service according to the specific mobile communication service subscription information.

In particular, the mobile communication service subscription information may be recorded in a SPID (Subscription Profile ID for RAT / Frequency Selection) included in the initial context setup request.

4 is a flowchart illustrating an initial access procedure of a mobile communication system to which a user context management method according to an embodiment of the present invention is applied. 4 is an exemplary diagram illustrating a connection procedure according to a mobile communication standard according to the 3GPP proposal.

Referring to FIG. 4, when the user apparatus 10 is to be connected to a mobile communication system by power on or the like, the mobility management apparatus 100 connected to the radio access apparatus 100 through a specific radio access apparatus 100 selected through a search procedure And transmits a connection request to the device 200 (S205). The connection request is transmitted through an Attach request message of the NAS message and is transmitted to the user equipment 10 using the identification information of the user equipment 10 such as International Mobile Equipment Identity (IMSI), Globally Unique Temporary Identifier (GUTI) Identity).

 If the user equipment 10 transmits a connection request including a GUTI based on the connection information of the previous network, the mobility management apparatus 200 determines whether the user equipment 10 has previously connected The information of the user equipment 10 can be received from the mobility management apparatus of one network and the identification procedure for the user equipment 10 can be performed.

Then, the mobility management apparatus 200 receiving the connection request of the user equipment 10 performs subscriber authentication and security processing on the user equipment 10 (S210). This is because the mobility management apparatus 200 requests and receives the authentication information from the subscriber information management apparatus 500 based on the identification information (IMSI) of the user apparatus 10, 10, and generating and setting a security key with the user device 10 after authentication. Thereafter, the control message is encrypted and transmitted based on the generated security key.

After completing the authentication and security procedures, the mobility management device 200 registers the location of the user device 10 and transmits the location information of the user 10 to the subscriber information management device 500, And transmits an Update Location request to the device 10 (S215). The subscriber information management apparatus 500 that has received the registration information registers the identification information of the mobility management apparatus 200 as the location information of the user apparatus 10, And transmits the subscriber profile information to the mobility management apparatus 200 (S220). The subscriber profile information may be delivered via a Update Location ACK message. The subscriber profile information includes at least one of APN information for a service subscribed by a user, identification information of a PDN gateway 400 for accessing the APN, information on subscribed QoS profiles (UE0AMBR, QCI, ARP, APN- Along with subscription information for a particular mobile communication service (e.

In the above process, an EPS session and a default EPS bearer may be generated, which may be performed according to a billing and QoS policy for the user device 10 provided from the subscriber policy management device 600.

If the authentication and security, the location registration, and the session creation procedure are normally performed, the mobility management apparatus 200 transmits a connection accept message (Attach Accept) in response to the connection request to the user apparatus 10 through the wireless access apparatus 100 (S235). The connection admission message is transmitted to the wireless access point 100 through the Initial Context Setup Request message described later in the S1 signaling connection and then transmitted from the wireless access point 100 to the user equipment 100 through the RRC Connection Reconfiguration message in the RRC connection. (10).

The wireless connection device 100 selected by the user device 10 may be initialized to the wireless connection device 100 selected by the user device 10 in order to control the mobility management device 200 and the wireless connection device 100 to perform a procedure for allocating wireless resources to the user device 10. [ And transmits an Initial Context Setup Request (S240). At this time, the mobility management apparatus 200 provides the wireless connection apparatus 100 with the subscription information of the specific mobile communication service together with security related information, performance information of the user apparatus 10, and bearer setting information. In particular, the mobile communication service subscription information may be recorded in a predetermined field of a Subscription Profile ID for RAT / Frequency Selection (SPID) included in the initial context setup request.

Upon receiving the initial context setup request, the radio access station 100 allocates radio resources for communication with the user equipment 10 and configures an RRC connection according to the allocated radio resources (S245). At this time, Confirms the subscription information of the specific mobile communication service included in the setup request, and verifies the terminal capability information collected from the user device 10. [ When the specific mobile communication service subscription information provided from the mobility management apparatus 200 matches the specific mobile communication service support information of the collected terminal performance information, a function corresponding to the specific mobile communication service, for example, Carrier Aggregation Function is activated, thereby setting the radio resource. On the other hand, when the specific mobile communication service support information of the collected terminal performance information does not match, that is, when the user device 10 does not support the specific mobile communication service, , The radio access station 100 allocates radio resources as defined in the LTE standard without applying carrier aggregation.

In step S250, the wireless access device 100 transmits an initial context setup response message to the mobility management device 200 in response to the initial context setup request.

In addition, the user equipment 10 having completed the setting of the radio resource notifies the mobility management apparatus 200 of the connection completion through the wireless connection apparatus 100 (S255) in response to the connection acceptance. The Attach Complete message is transmitted to the wireless access point 100 through the UL Information Transfer message and then transmitted to the mobility management apparatus 200 through the Uplink NAS Transport message. Lt; / RTI >

The mobility management apparatus 200 confirms that the radio connection between the user apparatus 10 and the radio access apparatus 100 has been completed in this manner and transmits the downlink SI TEID received from the radio access apparatus 100 to the serving gateway 300 And performs a session update procedure to be connected from the wireless access point 100 to the serving gateway 300 (S260).

The data transmission path is established through the wireless access device 100, the serving gateway 300, and the PDN gateway 400 through the above-described process, so that the user device 10 can receive the data communication service.

The user context management method according to the present invention may be implemented in a form of software readable by various computer means and recorded in a computer-readable recording medium. Here, the recording medium may include program commands, data files, data structures, and the like, alone or in combination.
