The area MME 130 may also include a connection request receiver 231, an area communication service subscriber identity part 232, and an area communication service subscriber information storage part 233.

The connection request receiving unit 231 receives a connection request signal for requesting connection to a communication service from a plurality of terminals including a terminal 300 located in a specific area. At this time, the connection request signal includes the identification information and the location information of the terminal 300. In the first embodiment of the present invention, when a terminal 300 located in a specific area requests a communication service, the terminal 300 is first connected to the area EPC 100. However, the present invention is not limited thereto.

The area communication service subscriber confirmation unit 232 stores the identification information of the terminal 300 included in the connection request signal received by the connection request receiving unit 231 and the area communication service subscriber information storage unit 233 to be described later Based on the information on the plurality of area subscribers in the terminal 300, that the user of the terminal 300 is the area subscriber. In the case of an area subscriber, information of a region P-GW 120, which is a component of the area EPC, is transmitted to the area S-GW 110 so that a specific communication service can be provided to the terminal 300 through the area P- .

However, if it is not an area subscriber, the terminal 300 is provided with a service through the public S-GW and the P-GW. Here, the form of the area P-GW 120 information and the common P-GW 220 information are not limited to any one.

The area communication service subscriber information storage unit 233 stores and manages information on area communication service subscribers that can receive a specific service in a specific area. Here, the information of the area communication service subscriber is described as an example of the terminal identification information of the corresponding service subscriber, but is not limited thereto. The area communication service subscriber information is updated according to a preset period or updated when a specific event occurs (for example, a new user is added to the area subscriber). In addition, the area communication service subscriber information storage unit 233 may store information on the public S-GW and the P-GW that can provide general communication services in the corresponding area.

A method for providing a service to a terminal 300 located in an area through the service providing system 100, which is the area EPC described above, will be described with reference to FIG.

As shown in FIG. 5, when the terminal 300 that has entered a specific area requests a network connection to use the communication service (S100), the base station receiving the connection request signal transmits a specific service corresponding to the specific area And transmits the connection request signal to the area MME 130 of the service providing system 100 (S110). Herein, the connection request signal includes the identification information of the terminal 300.

The area communication service subscriber identification unit of the area MME 130 determines whether the identification information in the connection request signal received in step S110 is stored in the area communication service subscriber information storage unit, that is, whether the user of the terminal 300 requesting the connection It is checked whether it is an area subscriber (S120). If it is an area subscriber, the area MME 130 provides information of the area P-GW 120 to the area S-GW 110 (S130) and transmits the information of the area P-GW 120 to the terminal 300 through the area P- A specific service and a general communication service are also provided (S140).

However, if it is determined in step S120 that it is not an area subscriber, the area MME 130 provides the information of the common P-GW 220 to the area S-GW 110 (S150). To this end, the area communication service subscriber information storage unit also stores information of the common EPC 200 that can provide a general communication service in the corresponding area. Accordingly, the area S-GW 110 receiving the information about the public P-GW 220 can provide a general communication service to the terminal 300 through the public P-GW 220 of the common EPC 200 (S160).

As described above, in an embodiment of the present invention, the MME in the common EPC 200 does not transmit information to the area MME 130 in the area EPC 100, And determines whether to provide the service using the common EPC 200 or the area EPC 100 in the area MME 130 based on the stored information.

Meanwhile, in another embodiment of the present invention, the PDN of the area EPC 100, that is, the area P-GW 120 may be connected according to the type of APN (Access Point Name) transmitted from the AT 300, Service or a specific service.

As shown in FIG. 6, the AT 300 includes an APN list providing unit 310 and an information transmitting unit 320.

The APN list provider 310 provides the user with a list of APNs that the terminal 300 can select. In the embodiment of the present invention, as an example, a public APN for providing a service through the common EPC 200 and an area APN for providing a service through the area EPC 100 are provided in a list Descriptions are not necessarily so limited.

The APN list providing unit 310 receives the APN selection information input by the user and transfers the APN selection information to the information transmitting unit 320. Here, the selection information includes information of the APN selected by the user and terminal identification information.

The information transmitting unit 320 transmits the selection information received from the APN list providing unit 310 to the MME of the EPC to which the terminal 300 is currently connected. The MME may be the MME 130 in the area EPC 100 or the MME 230 in the common EPC 200 according to the connection state of the terminal 300. [

According to another embodiment of the present invention, the MME 230 may further include a selection information receiving unit and an information delivering unit.

A selection information receiving unit (not shown) receives the selection information transmitted from the terminal 300. Based on the APN information included in the selection information, the selection information receiving unit 231 determines whether to provide the service through the EPC 200 or the EPC 100 based on the APN information.

The information transfer unit (not shown) transfers the terminal information to the MME in the EPC determined by the selection information receiving unit 231 to provide the service. Here, the terminal information means the identification information of the terminal, and is not necessarily limited thereto.
