Wireless communication system and method for establishing a connection between user equipment and a mobility management entity thereof
First Claim
1. A method by a mobility management entity (MME) in a communication system, the method comprising:
- receiving, from a terminal, a first request message;
transmitting, to a home subscriber server (HSS), a second request message related to the terminal based on the first request message;
receiving, from the HSS, a first response message in response to the second request message, the first response message including subscription information of the terminal;
allocating a tracking area update (TAU) timer value based on the subscription information of the terminal and information on an operator policy; and
transmitting, to the terminal, a second response message including the allocated TAU timer value.

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.
