Abstract

A method and device for accessing and obtaining user equipment (UE) context and UE identity are provided. The method for access includes: when a UE accesses a System Architecture Evolution (SAE) network, judging, by a network node, whether a Globally Unique Mobility Management Entity Identifier (GUMMEI) carried by the UE or a Mobility Management Entity Group Identity (MMEGI) in the GUMMEI is allocated or mapped by the SAE network; if the GUMMEI or MMEGI is allocated by the SAE network, selecting, by the network node, a Mobility Management Entity (MME) according to the GUMMEIA network device includes an identity attribute obtaining module and a network resource node allocation module. Therefore, the access of the UE is achieved.

Claims

1. A method for obtaining a user equipment (UE) context, the method comprising:

obtaining, by a UE, a temporary identity indicated by a Temporary Identity used in Next update (TIN) of the UE and obtaining an additional temporary identity of the UE;

determining, by the UE, whether the temporary identity indicated by the TIN of the UE is the same as the additional temporary identity of the UE; and

if the temporary identity indicated by the TIN of the UE is the same as the additional temporary identity of the UE transmitting, by the UE, the temporary identity indicated by the TIN to a base station, wherein the temporary identity indicated by the TIN is used by the base station to identify the UE context of the UE.

2. The method according to claim 1, wherein the additional temporary identity of the UE comprises an Additional GUTI (Global Unique Temporary Identity) of the UE.

3. An apparatus, comprising:

a processor, configured to obtain a temporary identity indicated by a Temporary Identity used in Next update (TIN) of the UE (user equipment) and obtain an additional temporary identity of the UE, and determine whether the temporary identity indicated by the TIN of the UE is the same as the additional temporary identity of the UE; and

a transmitter, configured to transmit the temporary identity indicated by the TIN to a base station if the temporary identity indicated by the TIN of the UE is the same as the additional temporary identity of the UE, wherein the temporary identity indicated by the TIN is used by the base station to identify a UE context of the UE.

4. The apparatus according to claim 3, wherein the additional temporary identity of the UE comprises an Additional GUTI (Global Unique Temporary Identity) of the UE.
