Embodiment Construction

[0058] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0059] see Figure 4 , which is a flow chart of a method for identifying user equipment in an evolved network according to an embodiment of the present invention, and the method includes:

[0060] Step 401: Receive the Temporary Mobile Subscriber Identity S-TMSI allocated for the user equipment accessing the evolved network, the S-TMSI includes: the resource pool identifier, the mobility management entity identifier and the temporary identifier of the user equipment;

[0061] Among them, the user equipment is assigned a new S-TMSI during the access process. Generally, when the UE accesses the network for the first time, or the UE enters a new Pool area from another Pool, or the UE initiates a location update process, the network decides to assign a new S-TMSI to the UE. S-TMSI and other cases.

[0062] Step 402: Use the S-TMSI to temporarily identif...

Abstract

The embodiment of the invention relates to a method and a device for identifying user equipment (UE) in an evolved network, and a mobility management entity (MME). The method comprises the following steps of: receiving a system architecture evolved-temporary mobile subscriber identity (S-TMSI) which is allocated for the UE accessing the evolved network, wherein the S-TMSI comprises a resource pool identity, an MME identity and a temporary identity of the UE; and temporarily identifying the UE in the evolved network by using the S-TMSI. The device comprises a receiving unit and a temporary identification unit. The MME comprises a temporary identity allocation unit. In addition, the invention also provides a method for transmitting and allocating the temporary identity and a method for receiving and transmitting information according to the temporary identity. By setting the resource pool identity on the S-TMSI, the aim of accelerating the updating and the processing of access equipment is fulfilled, the configuration of network resources of operators is simplified, and radio null interface resources are saved at the same time.

Description

technical field [0001] The present invention relates to communication technology, in particular to temporary mobile user identification. Background technique [0002] With the development of the network, in 3GPP, each manufacturer is actively researching the long-term evolution network (LTE, Long Term Evolved) / system architecture evolution network (SAE, System Architecture Evolved), and its structure diagram is as follows figure 1 shown, including: [0003] The function of the Mobility Management Entity 11 (MME, Mobility Management Entity) is to save the UE's mobility management context, such as user identity, mobility management status, location information, etc. Signaling processing, responsible for the security of NAS signaling, etc. [0004] The SAE gateway 12 (SAE GW) includes a serving gateway 121 (S-GW, Serving Gateway) and a packet data network gateway 122 (P-GW, PDN Gateway). S-GW and P-GW are two logical entities, which may exist in the same or different physica...
