Method and device for accessing and obtaining user equipment context and user equipment identity
First Claim
1. A communication method, comprising:
- when a temporary identity used in next update (TIN) in a user equipment (UE) indicates a packet temporary mobile subscriber identity (P-TMSI) type,generating, by the UE, a first global unique temporary identity (GUTI) from a P-TMSI and a routing area identity (RAI) held by the UE; and
when the UE determines that the UE holds a second GUTI allocated by a system architecture evolution (SAE) network, sending, by the UE, the generated first GUTI in a first information element (IE) of a tracking area updating (TAU) request and the second GUTI in an additional GUTI IE of the TAU request to a mobility management entity (MME) in the SAE network; and
when the TIN in the UE indicates a GUTI type or a radio access technology (RAT)-related temporary mobile subscriber identity (TMSI) type and the UE determines that the UE holds a third GUTI allocated by the SAE network,sending, by the UE, the third GUTI in the first IE in the TAU request without the additional GUTI IE.

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.

3. An apparatus, comprising a processing unit and a memory, wherein
the memory stores information including program codes, and the processing unit executes the program codes, causing the apparatus to execute: -
when a temporary identity used in next update (TIN) in the apparatus indicates a packet temporary mobile subscriber identity (P-TMSI) type, generating a first global unique temporary identity (GUTI) from a P-TMSI and a routing area identity (RAI) held by the apparatus; and when the apparatus determines that the apparatus holds a second GUTI allocated by a system architecture evolution (SAE) network, sending the generated first GUTI in a first information element (IE) of a tracking area updating (TAU) request and the second GUTI in an additional GUTI IE of the TAU request to a mobility management entity (MME) in the SAE network; and when the TIN in the apparatus indicates a GUTI type or a radio access technology (RAT)-related temporary mobile subscriber identity (TMSI) type and the apparatus determines that the UE holds a third GUTI allocated by the SAE network, sending the third GUTI in the first IE in the TAU request without the additional GUTI IE. - View Dependent Claims (4)

5. A non-transient computer readable medium, which stores program codes for execution by an apparatus in a communication system, wherein the program codes comprise instructions for performing the following:
-
when a temporary identity used in next update (TIN) in the apparatus indicates a packet temporary mobile subscriber identity (P-TMSI) type, generating a first global unique temporary identity (GUTI) from a P-TMSI and a routing area identity (RAI) held by the apparatus; and when the apparatus determines that the apparatus holds a second GUTI allocated by a system architecture evolution (SAE) network, sending the generated first GUTI in a first information element (IE) of a tracking area updating (TAU) request and the second GUTI in an additional GUTI IE of the TAU request to a mobility management entity (MME) in the SAE network; and when the TIN in the apparatus indicates a GUTI type or a radio access technology (RAT)-related temporary mobile subscriber identity (TMSI) type and the apparatus determines that the UE holds a third GUTI allocated by the SAE network, sending the third GUTI in the first IE in the TAU request without the additional GUTI IE. - View Dependent Claims (6)

7. A communication system, comprising a mobility management entity (MME) and a user equipment (UE), wherein:
-
the UE is configured to perform; when a temporary identity used in next update (TIN) in the UE indicates a packet temporary mobile subscriber identity (P-TMSI) type, generating a first global unique temporary identity (GUTI) from a P-TMSI and a routing area identity (RAI) held by the UE; and when the UE determines that the UE holds a second GUTI allocated by a system architecture evolution (SAE) network, sending the generated first GUTI in a first information element (IE) of a tracking area updating (TAU) request and the second GUTI in an additional GUTI IE of the TAU request to the mobility management entity (MME) in the SAE network; and when the TIN in the apparatus indicates a GUTI type or a radio access technology (RAT)-related temporary mobile subscriber identity (TMSI) type and the UE determines that the UE holds a third GUTI allocated by the SAE network, sending the third GUTI in the first IE in the TAU request without the additional GUTI IE; and the MME is configured to receive the TAU request from the UE. - View Dependent Claims (8)
