Claim:
A method for sending identity information in a system architecture evolved (SAE) network, comprising: receiving, by a processor, a system architecture evolved (SAE)-temporary mobile subscriber identity (SAE-TMSI) from a mobility management entity (MME) of the SAE network, wherein the SAE-TMSI comprises: a resource pool identifier (pool-ID), a mobility management entity identifier (MME-ID); and a UE temporary identifier; sending, by the processor, the SAE-TMSI to the MME or a new MME when a user equipment (UE) accesses the SAE network after reselecting the MME or changing to a new MME, wherein the SAE-TMSI is used for the MME or the new MME to identify the UE; and wherein the pool-ID is unique in public land mobile network (PLMN), the MME-ID is unique in a resource pool, and the LIE temporary identifier is unique in an MME.
