Problems solved by technology

For example, under the following circumstances, the two user mobility control management entities registered by the UE will not be able to continue to maintain the ISR function of the UE: the non-current user mobility control management entity registered by the UE has a failure problem, or the UE registered The S3 interface between two user mobility control management entities is faulty, or the service gateway is relocated due to overload protection, etc.
[0004] However, the method and process for deactivating the ISR function of the UE are not defined in the existing system

Embodiment 1

[0058] figure 2 It is a schematic flow chart of Embodiment 1 of the method of the present invention. Embodiment 1 provides a method for deactivating the ISR function of the UE initiated by the MME when the user mobility control management entity corresponding to the current camping area of ​​the UE is the MME. In this embodiment, the MME notifies based on the GUTI reassignment The ISR function of the UE has been deactivated in the MME, and the UE is triggered to perform corresponding deactivation of the ISR function. In the first embodiment, the MME is the first user mobility control management entity of the UE, and correspondingly, the SGSN is the second user mobility control management entity. like figure 2 As shown, embodiment one includes:

[0059] 201. The MME deletes the data associated with the SGSN in the context data related to the ISR function of the UE stored by the MME.

[0060] 202. The MME judges whether the UE is in an idle state, and if so, triggers the U...

Embodiment 2

[0069] image 3 It is a schematic flow chart of Embodiment 2 of the method of the present invention. Embodiment 2 provides a method for deactivating the ISR function of the UE initiated by the SGSN when the user mobility control management entity corresponding to the current camping area of ​​the UE is the SGSN. In this embodiment, the SGSN redistributes the UE based on the P-TMSI The process notifies the UE that its ISR function has been deactivated in the SGSN, and triggers the UE to perform corresponding deactivation of the ISR function. In the second embodiment, the SGSN is the first user mobility control management entity of the UE, and correspondingly, the MME is the second user mobility control management entity. like image 3 Shown, embodiment two comprises:

[0070] 301. The SGSN deletes the data associated with the MME in the stored context data related to the ISR function of the UE.

[0071] 302. The SGSN judges whether the UE is in an idle state, and if so, tri...

Abstract

The invention provides a method and a device for deactivating idle state signaling reduction (ISR) function. A first user mobility control and management entity of user equipment (UE) deletes data relevant to a second user mobility control and management entity in the context data which is relevant to the ISR function of the UE and saved by the first user mobility control and management entity and sends notifying message carrying the deactivating type identity to the UE so that the UE is informed of the deactivation of the ISR function thereof and is triggered to deactivate the ISR function at the side thereof, thus the ISR function of the UE can be deactivated in an evolution grouping system.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method and device for realizing deactivation of idle state signaling optimization (Idle State Signaling Reduction, ISR) function in an evolved packet system. Background technique [0002] In the Evolved Packet System of the 3rd Generation Cooperation Project, an idle-state signaling optimization technique is proposed, which can reduce idle-state user terminal (UE) camping on UTRAN / GSM / The signaling volume of the mobility management process when the two access systems of the Global System for Mobile Communications Evolved Enhanced Data Rate Radio Access Network (UTRAN / GERAN) and the Evolved Universal Terrestrial Radio Access Network (E-UTRAN) access the border area. The idle state means that there is no non-access stratum signaling connection between the UE and the user mobility control management entity corresponding to the current camping area. When the ISR function...
