Load bearing deleting method and device

Abstract

The invention discloses a load bearing deleting method. Two load bearing marks respectively corresponding to a first network and a second network are arranged for each user equipment in a service gateway; after the service gateway receives a request of deleting load bearing between the user equipment and the service gateway in the first network, which is sent by the network element of the first network, or a request of deleting load bearing between the user equipment and the service gateway in the second network, which is sent by the network element of the second network, the load bearing marks of the corresponding network of the user equipment are set to be deleted; and after two load bearing marks of the user equipment are both set to be deleted, load bearing between the service gatewayand a grouped data gateway of the user equipment is deleted. The invention can make clear the trigger time for deleting load bearing between SGW and PDN GW, improves trigger accuracy and efficiency in the process of deleting load bearing between SGW and PDN GW, prevents systems from maintaining unnecessary load, and improves system resource utility ratio.

Description

technical field [0001] The invention relates to the field of idle mode signaling reduction in a communication system, in particular to a bearer deletion method and device. Background technique [0002] In the third generation (3G) mobile communication system architecture evolution (SAE, System Architecture Evolution), in order to reduce the user equipment (UE, User Equipment) in the universal communication radio access network (UTRAN, Universal Telecommunication Radio Access Network) / enhanced A relatively fixed set of routes between the data rate GSM Evolved Technology Radio Access Network (GERAN, GSM EDGE Radio Access Network) and the Evolved Universal Telecommunications Radio Access Network (E-UTRAN, Evolved Universal Telecommunications Radio Access Network) Area (RA, Routing Area) and Tracking Area (TA, Tracking Area) move frequently, and a large number of imported routing area update (RAU, Routing Area Update) signaling or tracking area update (TAU, Tracking Area Updat...

Problems solved by technology

However, this solution does not describe in detail how to trigger the bearer deletion process between the SGW and the PDN GW. When the SGW receives the bearer deletion request sent by the MME or SGSN, it does not process it, and the two bearer deletion requests sent by the MME or SGSN The deletion messages may be separated for a long time, which leads to unclear triggering of the bearer deletion process between the SGW and the PDN GW in the prior art solution, so that the bearer deletion between the SGW and the PDN GW cannot be effectively completed
