Load creating method, deactivation method, service gateway and mobile communication system

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

Bearer creation method, deactivation method, serving gateway and mobile communication system technical field 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 In the evolution framework of 3GPP (3rd Generation Partnership Project, the third generation partnership project), the specifications 3GPPTS23.401 and 3GPPTS29.274 respectively define the creation and deletion signaling and procedures of the default bearer (Default bearer) and dedicated bearer (Dedicated bearer) . In addition, four trigger scenarios for user deactivation are defined, namely UE-initiated Detach procedure initiated by UE (User Equipment, user equipment), deactivation process initiated by MME (Mobility Management Entity, mobility management entity) ...

AI Technical Summary

Problems solved by technology

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
