Deleting method and system of EPS load

Abstract

The embodiment of the invention provides a deleting method and system of EPS load, aiming to delete idle EPS load and increase the utilization of network resources. The deleting method comprises the following steps: a first user mobile control management entity receives the attach request of user equipment; when the first user mobile control management entity determines that idle state signaling optimization ISR function identification of user equipment is triggered according to the context stored in the management entity of user equipment, the first user mobile control management entity triggers itself, and a second user mobile control management entity initiates the process of deleting the EPS load of user equipment, wherein the second user mobile control management entity is another wireless access type user mobile control entity registered by user equipment when the ISR function is triggered.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a method and system for deleting bearers of an Evolved Packet System (EPS, Evolved Packet System). Background technique [0002] The Attach process of a User Equipment (UE) is a process in which the UE registers with the EPS system. For example, when the UE is powered on, the UE registers with the EPS system through the Attach process and accepts EPS system services. [0003] The EPS system supports an Idle State Signaling Reduction (ISR, Idle State Signaling Reduction) function. [0004] When the ISR function of the UE is activated, the UE is simultaneously registered with the Universal Terrestrial Radio Access Network (UTRAN, Universal Terrestrial Radio Access Network) / Global System for Mobile Communications (GSM, Global System for Mobile communication) / GSM Evolution Enhanced Data Rate ( EDGE, Enhanced Data rates for GSM Evolution) radio access network (GER...

Problems solved by technology

Even if the new MME finds that the UE still has the undeleted EPS bearer, step 7 is executed, that is, the new MME initiates the process of deleting the EPS bearer to the Serving GW, but at this time, the Serving GW only deactivates the ISR function of the UE, and does not Send a delete bearer request message to the PDN GW. At this time, the old SGSN, Serving GW, and PDN GW in the network still retain the EPS bearer allocated for the UE before the UE attaches. The network resources at this time have not been completely and timely deleted. Reduce the utilization of network resources, and reduce the capacity and reliability of the network
