Abstract

The present invention relates to a wireless communication system and method for establishing connection between a User Equipment (UE) and a Mobility Management Entity (MME) in the wireless communication system in which the data-centric terminal requests the mobility management entity for attachment and checks, when the mobility management entity responds, data-centric features supported by the mobility management entity. According to the present invention, it is possible to connect the data-centric terminal to the mobility management entity supporting the data-centric features of the corresponding data-centric terminal efficiently in the wireless communication system.

Claims

1. A method by a base station in a wireless communication system, the method comprising:

receiving, from a machine type communication (MTC) terminal, an attach request message;

selecting a mobility management entity (MME) to which the attach request message is transmitted based on subscription information for the MTC terminal; and

transmitting, to the MME, the attach request message,

wherein the subscription information indicates that the MTC terminal is associated with an MTC function and is obtained from a home subscriber server (HSS).

2. The method of claim 1, wherein the MME is selected based on the subscription information in a network node selection function (NNSF) of the base station.

3. The method of claim 1, wherein the attach request message comprises information for a specific MME.

4. The method of claim 1, further comprising:

receiving, from the MME, an attach accept message; and

transmitting, to the MTC terminal, the attach accept message.

5. A base station in a wireless communication system, the base station comprising:

a transceiver configured to transmit and receive a signal; and

a controller configured to;

receive, from a machine type communication (MTC), terminal, an attach request message,

select a mobility management entity (MME) to which the attach request message is transmitted based on subscription information for the MTC terminal, and

transmit, to the MME, the attach request message,

wherein the subscription information indicates that the MTC terminal is associated with an MTC function and is obtained from a home subscriber server (HSS).

6. The base station of claim 5, wherein the MME is selected based on the subscription information in a network node selection function (NNSF) of the base station.

7. The base station of claim 5, wherein the attach request message comprises information for a specific MME.

8. The base station of claim 5, wherein the controller is further configured to:

receive, from the MME, an attach accept message, and

transmit, to the MTC terminal, the attach accept message.

9. A method by a machine type communication (MTC) terminal in a wireless communication system, the method comprising:

transmitting, to a base station, an attach request message; and

receiving, from the base station, an attach accept message,

wherein the attach request message is transmitted to a mobility management entity (MME) via the base station, and the attach accept message is received from the MME via the base station,

wherein the MME is selected based on a subscription information for the MTC terminal, and

wherein the subscription information indicates that the MTC terminal is associated with an MTC function and is obtained from a home subscriber server (HSS).

10. The method of claim 9, wherein the MME is selected based on the subscription information in a network node selection function (NNSF) of the base station.

11. The method of claim 9, wherein the attach request message comprises information for a specific MME.

12. A machine type communication (MTC) terminal in a wireless communication system, the MTC terminal comprising:

a transceiver configured to transmit and receive a signal; and

a controller configured to;

transmit, to a base station, an attach request message, and

receive, from the base station, an attach accept message,

wherein the attach request message is transmitted to a mobility management entity (MME) via the base station, and the attach accept message is received from the MME via the base station,

wherein the MME is selected based on a subscription information for the MTC terminal, and

wherein the subscription information indicates that the MTC terminal is associated with an MTC function and is obtained from a home subscriber server (HSS).

13. The MTC terminal of claim 12, wherein the MME is selected based on the subscription information in a network node selection function (NNSF) of the base station.

14. The MTC terminal of claim 12, wherein the attach request message comprises information for a specific MME.
