Wireless communication system and connection method between user equipment and a mobility management entity
First Claim
1. A connection method of a first mobility management entity (MME) comprising:
- receiving, from a base station, an initial UE message for a user equipment (UE);
determining whether an allocation of a temporary identity for the UE is required;
determining whether the UE is configured for a machine type communications (MTC) based on received information associated with the UE from a home subscriber server (HSS), in response to a determination that the allocation of the temporary identity for the UE is required;
identifying a second MME the UE configured for the MTC in response to a determination that the allocation for the temporary identity of the UE is required and the UE is configured for the MTC; and
transmitting, to the base station, a request message requesting reselection of an MME and including non-access stratum (NAS) message included in the initial UE message,wherein the received information associated with the UE includes an indicator indicating that the UE is configured for the MTC, andwherein the request message includes an identity of the second MME supporting the UE configured for the MTC.

Abstract
The present invention relates to a wireless communication system and a connection method between user equipment and a mobility management entity and comprises: selecting a mobility management entity and requesting identification information for user equipment by a base station when the user equipment is connected; determining whether to assign identification information by the mobility management entity; and if the identification information is not assigned, selecting another mobility management entity by the mobility management entity, assigning identification information to the user equipment by the other mobility management entity, and performing a connection with the other mobility management entity by the user equipment. According to the present invention, user equipment can be efficiently connected with a mobility management entity in a wireless communication system.
