Method and device for releasing context-related resources of user equipment

Abstract

The embodiment of the invention provides a method and device for releasing user equipment context related resources. The method for releasing the user equipment context related resources includes the steps that a source intermediate node receives control information, wherein the control information carries identification of user equipment switched into a target access network node; the source intermediate node releases the user equipment context related resources corresponding to the identification of the user equipment. By means of the method and device, the user equipment context related resources in the source intermediate node can be released, then the user equipment of a new access network can be smoothly connected, and the resources are saved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communications technologies, and in particular, to a method and device for releasing context-related resources of user equipment. Background technique [0002] In a wireless communication network, a typical network architecture consists of a radio access network and a core network, and the radio access network and the core network are connected through an interface. The wireless access network and the connected terminal are connected through a wireless interface to provide services for the terminal. [0003] With the development of technology, a new network architecture has emerged, which is to introduce an intermediate node between the access network node and the core network node. This intermediate node acts as a proxy node between the access network node and the core network node: from the perspective of the core network, the intermediate node is functionally an access network node; from t...

[0013] However, compared with cases (1), (3) and (5), in cases (2) and (4) the source GW also has the context-related resources of the UE that has been handed over to the target eNB. In the solution of releasing the UE context, the source GW will not be aware that the UE has left the jurisdiction of the source GW during and after the X2 handover, which will cause the UE context-related resources on the source GW to not be released. The context-related resources include The source GW uses all the resources for the UE on the user plane and the control plane, which will lead to the failure of the new UE to access the network and the exhaustion of resources
