Embodiment Construction

[0038]Embodiments of the present invention provide a method, system and device for UE detachment, which are used to prevent existing user mobility control management entities from deleting PDP Context or EPS Bearers due to loss of periodic updates.

[0039] The user mobility control management entity in the embodiment of the present invention refers to MME or SGSN. Since the UE needs to be registered on the SGSN and MME, for the convenience of expression, one of the user mobility control management entities (hereinafter referred to as UEMCME 1) is called a user mobility control management entity whose radio access type (RAT, RadioAccess Type) is RAT 1, Another user mobility control management entity (hereinafter referred to as UEMCME 2) is a user mobility control management entity whose wireless access type is RAT 2, that is, when the UEMCME 1 of the RAT 1 system is an SGSN, the UEMCME 2 of another RAT 2 system is the MME; when the UEMCME 1 of the RAT 1 system is the MME, the ...

Abstract

The invention discloses a user terminal detaching method, which comprises that: when a first user mobile control management entity of a first radio access type RAT system registered by a user terminal in an idle state does not receive a periodic position update request sent by the user terminal before a first user reachable timer overtimes, the first user mobile control management entity sets a first reachable state parameter value used for recording the update state of a periodic position area as nonupdated; the first user mobile control management entity checks the activation state of an idle state signaling optimization ISR function of the user terminal according to the context of the user terminal; and when the ISR function of the user terminal is activated and a second reachable state parameter value used for recording update state of the periodic position area in a second user mobile control management entity of a second RAT system registered by the user terminal is not updated, the first user mobile control management entity detaches the user terminal.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, system and device for deattaching a user terminal. Background technique [0002] Idle State Signaling Reduction (ISR, Idle State Signaling Reduction) technology is a technology proposed by Evolved Packet System (EPS, Evolved Packet System) of 3GPP. When the ISR function of the user terminal (UE) is activated, the UE is simultaneously registered to the Universal Terrestrial Radio Access Network (UTRAN, Universal Terrestrial Radio Access Network) / Global System for Mobile Communications (GSM, Global System for Mobile communication) / GSM evolution enhancement Data rate (EDGE, Enhanced Data rates for GSM Evolution) radio access network (GERAN, GSM / EDGE Radio Access Network) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network) access system On the User Mobility Control Management Entity (UEMC...
