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 for communication at a mobility management entity (MME) in a communication system, the method comprising:

receiving an attach request message from a terminal;

transmitting a subscription information request message for the terminal to a home subscriber server (HSS);

receiving a subscription information response message comprising a subscription information of the terminal and tracking area update (TAU) timer information for the terminal from the HSS; and

transmitting an attach response message based on the subscription information of the terminal to the terminal, the attach response message comprising the TAU timer information for the terminal.

2. The method of claim 1, further comprising:

receiving a TAU message from the terminal based on the TAU timer information.

3. The method of claim 1, wherein the receiving an attach request message comprising:

receiving operator policy information from the terminal, and

wherein transmitting an attach response message comprising

transmitting the attach response message based on the subscription information of the terminal and operator policy information.

4. The method of claim 1, further comprising:

determining whether the MME supports the terminal operation based on the subscription information of the terminal; and

transmitting, if the MME does not support the terminal operation, a reject message to the terminal.

5. The method for communication at a terminal in a communication system, the method comprising:

transmitting an attach request message to a mobility management entity (MME), the MME configured to transmit a subscription information request message for the terminal to a home subscriber server (HSS) and to receive a subscription information response message comprising a subscription information of the terminal and tracking area update (TAU) timer information for the terminal from the HSS; and

receiving an attach response message based on the subscription information of the terminal from the MME, the attach response message comprising the TAU timer information for the terminal.

6. The method of claim 5, further comprising:

transmitting a TAU message to the MME based on the TAU timer information.

7. The method of claim 5, wherein the transmitting attach request message comprising:

receiving operator policy information from an operator server; and

transmitting the received operator policy information to the MME,

wherein receiving an attach response message comprising

receiving the attach response message based on the subscription information of the terminal and operator policy information.

8. The method of claim 5, further comprising:

receiving, if the MME does not support the terminal operation, a reject message to the terminal, the MME configured to determine whether the MME supports the terminal operation based on the subscription information of the terminal.

9. A mobility management entity (MME) in a communication system, comprising:

a transceiver configured to transmit and receive signal to and from a terminal; and

a controller configured to receive an attach request message from a terminal, to transmit a subscription information request message for the terminal to a home subscriber server (HSS), to receive a subscription information response message comprising a subscription information of the terminal and tracking area update (TAU) timer information for the terminal from the HSS and to transmit an attach response message based on the subscription information of the terminal to the terminal, the attach response message comprising the TAU timer information for the terminal.

10. The MME of claim 9, wherein the controller further configured to receive a TAU message from the terminal based on the TAU timer information.

11. The MME of claim 9, wherein the controller further configured to receiving operator policy information from the terminal and to transmit the attach response message based on the subscription information of the terminal and operator policy information.

12. The MME of claim 9, wherein the controller further configured to determine whether the MME supports the terminal operation based on the subscription information of the terminal and to transmit, if the MME does not support the terminal operation, a reject message to the terminal.

16. The terminal of claim 12, wherein the controller further configured to receiving if the MME does not support the terminal operation, a reject message to the terminal, the MME configured to determine whether the MME supports the terminal operation based on the subscription information of the terminal.

13. A terminal in a communication system, comprising:

a transceiver configured to transmit and receive signal to and from a mobility management entity (MME), MME configured to transmit a subscription information request message for the terminal to a home subscriber server (HSS) and to receive a subscription information response message comprising a subscription information of the terminal and tracking area update (TAU) timer information for the terminal from the HSS; and

a controller configured to transmit an attach request message to a MME and to receive an attach response message based on the subscription information of the terminal from the MME, the attach response message comprising the TAU timer information for the terminal.

14. The terminal of claim 13, wherein the controller further configured to transmit a TAU message to the MME based on the TAU timer information.

15. The terminal of claim 13, wherein the controller further configured to receive operator policy information from an operator server, to transmit the received operator policy information to the MME and to receive the attach response message based on the subscription information of the terminal and operator policy information.
