Embodiment Construction

[0036] Embodiments of the present invention provide a resource release method and device to solve the problem of inconsistency of bearer resources between the PGW and the SGW.

[0037]In any system, the problem of resource inconsistency may lead to the failure or abnormality of the subsequent process. Therefore, if the problem of resource inconsistency between different network elements in the communication system can be solved efficiently, the stability of the system will be greatly improved. . However, when the Create_Bearer_Rsp message sent by the SGW to the PGW is lost during the bearer creation process, the resources between the SGW and the PGW can be kept consistent through the technical solutions provided by the embodiments of the present invention.

[0038] In the technical solution provided by the embodiment of the present invention, in the process of creating a dedicated bearer, the PGW will send a Create_Bearer_Req message to the SGW, and the message will carry info...

Abstract

The invention discloses a resource releasing method and device for solving the problem of inconsistent bearing resources between PGW (PDN gateway) and SGW (serving gateway). The resource releasing method comprises the steps of sending a bearing deleting request which carries a user plane channel identifier of the PGW, to the SGW after the grouping data network gateway PGW sends a bearing establishing request to the service gateway SGW if the bearing establishing response replied from the SGW is not received in a preset waiting time span; and enabling the PGW to release the bearing resource corresponding to the bearing establishing request.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for releasing resources. Background technique [0002] In the Long Term Evolution (LTE) system, the standard GPRS Tunneling Protocol for Control plane (GPRS Tunneling Protocol for Control plane, GTPC) interface, the parameters are passed through the GTPC message. In a mobile communication system, message loss often occurs due to abnormal communication, which may lead to resource inconsistency between the message sender and the message receiver after the message is lost. An important function of the PGW network element is to perform bearer management. When the user equipment (UE) side or the network side needs to create a dedicated bearer, the PGW will send a create bearer request message (Create_Bearer_Req) ​​to the SGW. In this message It will carry information such as the user plane tunnel identifier (TEIDU) of the PGW local end, bearer qual...
