Problems solved by technology

[0008] However, the first method cannot ensure that the user reactivates in exactly the same way. If the user does not reactivate in the same way, the original residual bearer cannot be deleted; the second method relies on path detection between network elements, If no problem is found in the path detection between network elements, the user will not be deactivated, and the remaining bearer cannot be deleted.
Therefore, neither of the above two methods in the prior art can completely solve the problem of residual bearing

Embodiment Construction

[0032] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0033] figure 1 A flow chart showing an embodiment of the method for creating a bearer in the SAE of the present invention.

[0034] Such as figure 1 As shown, in step 102, during the bearer creation process, the SGW receives a bearer creation request from the first network element. For example, during the creation of a default bearer, the SGW receives a request message to create a default bearer from the MME (the first network element); during the creation of a dedicated bearer, the SGW receives a creation dedicated Bearer request message.

[0035] In step 104, the SGW forwards the bearer creation request to the second network element. For example, in the process of creating a default bearer, the SGW forwards the request message of creating a default bearer to the PGW (the second network eleme...

Abstract

The invention discloses a load creating method, a deactivation method, a service gateway and a mobile communication system in SAE (System Architecture Evolution). The load creating method comprises the following steps of: receiving a load creating request of a first network element by the service gateway; transmitting the load creating request to a second network element by the service gateway; receiving a response of successful load creation from the second network element by the service gateway; and when the service gateway fails to process the load creation, sending a deleting request to the second network element. The method, the service gateway and the system fundamentally solve the problem of residual loads of relevant network elements, caused by various reasons, by optimizing the flow of the traditional default load and the special load and adding the initiative starting user deactivation flow of the service gateway.

Description

technical field [0001] The present invention relates to the fourth-generation mobile communication technology, and in particular to a bearer creation method, a bearer deactivation method, a service gateway and a mobile communication system in SAE (System Architecture Evolution, System Architecture Evolution). Background technique [0002] In the evolution framework of 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project), the specifications 3GPP TS 23.401 and 3GPP TS 29.274 respectively define the creation and Delete signaling and procedures. In addition, 4 triggering scenarios for user deactivation are defined, namely UE-initiated Detach procedure initiated by UE (User Equipment, user equipment), UE-initiated Detach procedure initiated by MME (Mobility Management Entity, mobility management entity) The deactivation processing procedure (MME-initiated Detachprocedure), SGSN (Service GPRS Support Node, GPRS service support node) initiates the deactiva...
