Problems solved by technology

[0009] In the process of implementing the present invention, the inventors found that the above processing flow is a specific processing flow in the 3GPP communication network. When the UE moves to a non-3GPP communication network , the specific processing flow in the 3GPP communication network cannot be processed in the non-3GPP communication network, that is, the resources of the UE in the 3GPP communication network cannot be released

Embodiment Construction

[0038]The embodiment of the present invention proposes a method for network resource release processing, including the steps: after the user equipment using the ISR mechanism is registered to two 3rd Generation Partnership Project 3GPP communication networks, when the user equipment changes from the 3GPP communication network to (including switching to) a non-3GPP communication network (specifically including the user equipment moving to a non-3GPP network, the non-3GPP network initiates the process of attaching to the non-3GPP network, or the user equipment initiates attaching to the non-3GPP network in the 3GPP network processing procedure), the serving gateway receives the message sent by the peer network element, and deletes the network resources established by the two 3GPP communication networks for the user equipment according to the information carried in the message.

[0039] Wherein, the message sent by the peer network element received by the serving gateway includes ...

Abstract

The invention discloses a method for releasing and processing network resources, comprising the following steps: after user equipment using an ISP mechanism registers two 3GPP communication networks and when the user equipment changes the 3GPP network into a non 3GPP communication network, the service gateway receives a message sent by an opposite end network element and deletes the network resources which is established by the two 3GPP communication networks for the user equipment according to the massage. The invention also discloses a mobility management network element and the service gateway. The embodiment of the method and equipment for releasing and processing the network resources realizes the releasing of resources when the user using the ISP mechanism equipment changes the 3GPP network into the non 3GPP communication network.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a method for releasing network resources, a mobility management network element, and a service gateway. Background technique [0002] With the development of communication technology, in order to enhance the competitiveness of future networks, the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) is studying a new evolution network, its system architecture is as follows: figure 1 shown, including: [0003] Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (Evolved UMTS Territorial Radio Access Network, E-UTRAN), used to implement functions related to the wireless of the evolved network; Mobility Management Entity (Mobility Management Entity , MME), responsible for the mobility management of the control plane, including user context and mobility state management, assigning temporary user IDs, etc.; servin...
