Embodiment Construction

[0033] Embodiments of the present invention provide an ISR method and system thereof. In order to make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0034] Please refer to figure 1 , is a flow chart of the first embodiment of the ISR method of the present invention. In this embodiment, the user equipment is supported to keep the ISR activation state of the user equipment after switching to the target network when the source network has activated the ISR.

[0035] During the handover execution process before the routing area or tracking area update process, when the target network mobility management NE sends an update bearer request to the target network service gateway, if the target network mobility management NE has the ability to support ISR, the update bearer The request message carries information instructing the SGW to maintain the cur...

Abstract

The embodiment of the invention provides a method for saving a signalling, and a system thereof. The ISR method comprises the following steps: acquiring the ISR capacity of a target network mobility management network element; and setting the ISR state of user equipment in a target network according to the ISR capacity of the target network mobility management network element. The technical scheme provided by the embodiment of the invention can process the ISR state of the user equipment when the user equipment performs network switching.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for Idle modesignalling reduction (ISR, ISR). Background technique [0002] In areas where different 3rd Generation Partnership Project (3GPP) access technology networks overlap or are adjacent, mobile users change access systems every time, such as from radio access network / universal terrestrial radio access network (GERAN / UTRAN) to The Evolved Universal Terrestrial Radio Access Network (EUTRAN), or from EUTRAN to GERAN / UTRAN, needs to initiate a location update process, so it will bring a certain load to the core network and air interface. In order to avoid the above signaling load and optimize the mobility management mechanism between different 3GPP access systems, 3GPP proposed the ISR mechanism in idle mode to reduce the mobility of user equipment (UE, UserEquipment) between different access networks The signaling load brought by the manag...
