METHOD AND DEVICE FOR ACCESSING AND OBTAINING USER EQUIPMENT CONTEXT AND USER EQUIPMENT IDENTITY

摘要

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 GUMMEI, or according to the MMEGI and a Mobility Management Entity Code (MMEC), or according to a Public Land Mobile Network Identity (PLMN-id), the MMEGI and the MMEC; and if the GUMMEI or MMEGI is mapped by the SAE network, selecting, by the network node, an MME according to a Mobile Country Code (MCC), a Mobile Network Code (MNC) and an MMEC in the GUMMEI, or according to the MMEC in the GUMMEI, or according to a selected PLMN-id and the MMEC in the GUMMEI. A network device includes an identity attribute obtaining module and a network resource node allocation module. Therefore, the access of the UE is achieved.
