In the above, the external network may include one or more of a mobile communication network of another provider, an IP Multimedia Subsystem (IMS) network, or an Internet network. Here, the IMS network and the Internet network are IP-based packet data networks.

The access network includes a plurality of radio access devices (100).

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).

To this end, the wireless access device 100 generates system information and broadcasts necessary control information in the communication coverage so that the user device 10 can search for itself. In this case, the system information includes a Public Land Mobile Network Identifier (PLMN ID), an eNB Cell Global ID (ECGI), and a Tracking Area ID ; TAI).

In addition, the wireless access device 100 may collect and analyze channel measurement result information of cells adjacent to the current cell from the user equipment 10, determine handover, and instruct a handover. To this end, the wireless access point 100 may support a control protocol such as a Radio Resource Control Protocol related to radio resource management.

Particularly, in the present invention, the radio access device 100 is a device that supports a specific mobile communication service (for example, 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.

In particular, in the present invention, the mobility management apparatus 200 performs location registration in conjunction with the subscriber information management apparatus 500 and obtains subscriber profile information at the initial connection of the user apparatus 10, (10) is subscribed to a specific mobile communication service based on the access point name information included in the subscriber profile information, and transmits the specific mobile communication service subscription information of the user device (10) to the user device To the wireless access device 100 to be connected. At this time, the specific mobile communication service subscription information may be transmitted through a specific field or maximum bandwidth information (UE-AMBR) in the SPID of the initial context setup request. For example, the specific mobile communication service subscription information may be displayed as a value indicating whether to join a specific field in the SPID of the initial context setup request. In another case, the specific mobile communication service subscription information may be represented by maximum bandwidth information having a predetermined value for a specific mobile communication service.

Next, the serving gateway 300 may serve as a mobility anchor when handing over or between the wireless access points 100 of the user equipment 10. 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 addition, the PDN gateway 400 performs QoS policies differently for each user device 10 in cooperation with the subscriber policy management apparatus 600, controls traffic and performs billing processing.

In particular, the serving gateway 300 and the PDN gateway 400 create a session for the user device 10.

In this case, the PDN gateway 400 includes a plurality of PDN gateways classified into a packet data network and a service provided through the packet data network. In particular, in the present invention, a PDN Gateway. That is, the PDN gateway 400 is allocated for each access point name.

When the PDN gateway 400 is allocated to the user equipment 10, the mobility management apparatus 200 according to the present invention transmits the access point name information to the user equipment (UE) 100 based on the access point name information provided from the subscriber information management unit 500 10 are subscribed to a specific mobile communication service, a PDN gateway is allocated for the specific mobile communication service.

Next, the subscriber information management apparatus 500 manages the information on the subscriber and the mobility information. 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. [

In particular, in the present invention, the subscriber information management apparatus 500 confirms the subscriber profile information of the user device 10, and when the user device 10 is subscribed to a specific mobile communication service, Function, the access point name of the user device 10 is updated to the preset access point name information for the specific mobile communication service. Then, the subscriber profile information including the updated access point name information is provided to the mobility management apparatus 200.

Typically, the access point name is comprised of a network ID (APN-NI) and a provider ID (APN-OI). At this time, the network ID can not be changed because it is an identifier for the packet network data such as the Internet and IMS network. Therefore, in the present invention, the update of the access point name may be performed by changing the business entity ID to a value set corresponding to the specific mobile communication service.

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.

In the above-described configuration, the user equipment 10 uses the data transmission path via the wireless access point 100, the serving gateway 300, and the PDN gateway 400 to access an external packet data network (IMS) 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 procedures for the user equipment 10, the location registration procedure, and the session creation procedure are sequentially performed through the mobility management apparatus 200, 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.

The mobility management apparatus 200 according to the present invention may be configured such that when registering the first location of the user equipment 10, the mobility management apparatus 200 receives, from the access point name information received from the subscriber information management apparatus 500, Confirms the subscription information, and stores it in the user context.

Next, a session between the serving gateway 300 and the PDN gateway 400 for the user equipment 10 is created. This process will be described with reference to FIG.

Referring to FIG. 2, in the mobile communication system according to the present invention, there may be at least one packet data network 21, 22 to be connected to the user equipment 10. Here, the first packet data network 21 is an Internet network and the second packet data network 22 is an IMS network.

APNs 1 to 3 exist for the first and second packet data networks 21 and 22. In the present invention, APNs for a specific mobile communication service (for example, LTE-A, for example, APN1). The PDN gateways 401 to 403, which are connectable to the APNs 1 to 3, are separately set.

In this state, the subscriber information management device 500 provides APN information provisioned for the user device 10 to the mobility management device 200 when providing the subscriber profile information. At this time, when the user equipment 10 is subscribed to a specific mobile communication service, the provided APN information is updated for a specific mobile communication service.

When the APN information is updated for a specific mobile communication service, the mobility management apparatus 200 allocates a PDN gateway for providing a PDN connection to the user equipment 10 using the APN information. At this time, The management apparatus 200 refers to the domain information and allocates the PDN gateway 401 mapped to the APN1 and set for the specific mobile communication service. The user equipment 10 is connected to the first packet data network 21 through the PDN gateway 401. On the other hand, when the APN information is not updated for a specific mobile communication service, the mobility management apparatus 200 does not subscribe to a specific mobile communication service, And the user device 10 is connected to the first packet data network 21 via the PDN gateway 402. [ On the other hand, the second packet data network 22 corresponding to the IMS network can be connected through the PDN gateway 403 without distinguishing the specific mobile communication service.

After generating the session for the PDN connection to the user equipment 10, the mobility management apparatus 200 transmits the session to the radio access apparatus 100 in the communication coverage area in which the user apparatus 10 has entered And provides the specific mobile communication service subscription information.

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.

Hereinafter, the configuration and operation of an apparatus for providing a mobile communication service according to the present invention in the above-described mobile communication system will be described in more detail.

The storage unit 520 stores data necessary for operation of the subscriber information management apparatus 500. In particular, the storage unit 520 includes subscriber profile information including service subscription information for a plurality of subscribers . In addition, the subscriber profile information is stored corresponding to the identification information (e.g., IMSI) of the user equipment 10, and may include the APN information set for the user equipment 10.

The controller 530 is a structure for performing main functions of the subscriber information management apparatus 500, for example, subscriber authentication and location registration. In particular, the control process of the controller 530 according to the present invention will be described with reference to FIG.

4, the controller 530 receives a location registration request for a specific user device 10 from the mobility management device 200 via the communication interface 510 (S110) 10) and the identification information (e.g., MMEI) of the mobility management apparatus 200, thereby performing location registration of the user apparatus 10. [ In addition, a location registration procedure for extracting corresponding subscriber profile information based on the identification information of the user equipment 10 and providing the extracted subscriber profile information to the mobility management apparatus 200 is performed.

At this time, the controller 530 of the subscriber information management apparatus 500 according to the present invention refers to the subscriber profile information to check whether the user equipment 10 is subscribed to a specific mobile communication service, (Step S120). If the specific mobile communication service function is not supported,

If it is determined that the user equipment 10 is subscribed to a specific mobile communication service and the terminal capability supports the specific mobile communication service in steps S130 and S140, the control unit 530 instructs the user equipment 10 The set APN information is updated for a specific mobile communication service (S150). Here, the update of the APN information may be performed by changing the OI (provider ID) portion of the APN information for a specific mobile communication service.

After the location registration, the controller 530 provides subscriber profile information including the updated APN information to the mobility management apparatus 200 (S160).

On the other hand, if the UE 10 is not subscribed to the specific mobile communication service or if the UE performance does not support the specific mobile communication service in steps S130 and S140, the control unit 530 transmits the APN Information to the mobility management apparatus 200 without updating the information for the specific mobile communication service (S170). That is, at this time, the transmitted APN does not include setting information corresponding to a specific mobile communication service.

Accordingly, the mobility management apparatus 200 can confirm whether the user apparatus 10 is subscribed to a specific mobile communication service by checking the APN information provided from the subscriber information management apparatus 500. [
