Embodiment Construction

[0031] The first and second embodiments of the present invention image 3 Shown. The following is a detailed description of the figure. In the following description, detailed technical descriptions are omitted for technologies not related to the present invention.

[0032] In step 301, the UE is in idle mode and needs to send area update messages periodically. Or the UE moves to a new area and needs to send an area update message. The UE sends an RRC connection establishment request message to the eNB. The message contains the identity of the UE and the identity of the PLMN selected by the UE.

[0033] In step 302, the eNB sends a response message "RRC connection establishment" to the UE. The message contains the UE's identity and the configuration of the signaling connection.

[0034] In step 303, the UE sends an "RRC connection complete" message to the eNB. The message contains the NAS message "area update" message. The "area update" message contains the identity of the UE, such...

Abstract

A method for supporting the releasing of resources of an S1 interface and an air interface comprises the following steps that: a mobile management entity MME receives a non access stratum NAS message sent by UE; and the MME sends a response message of the NAS message to eNB and instructs the eNB to release the connection of the S1 interface of the UE. The method can release the resources of the air interface and the S1 interface and simultaneously make the MME transmit the NAS message.

Description

Technical field [0001] The present invention relates to the field of communication, in particular, a method for releasing UE resources on the S1 interface and the air interface under an enhanced network. Background technique [0002] The SAE system structure is as figure 1 Shown. Below is the right figure 1 Description of SAE system structure. [0003] 101 user equipment (hereinafter referred to as UE) is a terminal device used to receive data. 102EUTRAN is the wireless access network in the evolution system SAE, which can also be called ENB. It is responsible for providing an interface for LTE mobile phones to access the wireless network, and is connected with the mobile management entity 103MME and the user plane entity 104 Serving Gateway through the S1 interface. The 103MME is responsible for managing the mobile context and session context of the user equipment, and saving the user's security-related information. 104Serving Gateway mainly provides user plane functions. The ...
