Embodiment Construction

[0054] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0055] The present invention provides a method for optimizing resource processing of a core network gateway SGW, referring to figure 1 , in one embodiment, the method for optimizing resource processing of the core network gateway SGW includes the following steps:

[0056] Step S101, when the location of the user equipment UE changes, receiving the handover request message sent by the target mobility management entity Target MME and the resource processing temporary rejection message responded by the Source MME;

[0057] In this embodiment, when the location of the UE changes, the Target MME will send a handover request message to the SGW, notifying the SGW that the handover between the Source MME and the Target MME is taking place and other relevant UE information.

[0058] In this embodiment, since the Source MME an...

Abstract

The present invention discloses an SGW resource processing optimization method, which includes the following steps: receiving a handover request message sent by a Target MME and a resource processing temporary rejection message sent by a Source MME when the location of the UE changes; processing a handover request message, and And returning the handover success response to the Target MME. When the source MME and the Target MME complete the UE resource handover, the resource processing request message is sent to the Target MME, and the resource processing is performed after receiving the resource processing success message of the Target MME response. The present invention can ensure that the UE successfully creates, updates, and deletes the UE resources when the MME handover occurs.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an optimization method for core network gateway resource processing, a service gateway and an optimization system. Background technique [0002] EPS (Evolved Packet System, Evolved Packet System) is a network architecture based on IP (I-Internet Protocol, Internet Protocol) proposed by 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project). An open and flexible service environment can support UE (User Equipment, user equipment) to access the IP network, provide users with fast and stable access status, and can also meet the increasing demand of IP data traffic by improving packet switching technology. The existing specifications about UE's access to IP network through EPS, such as 3GPP TS 23.401 and 3GPP TS 29.274, already have signaling and process descriptions for handover of UE in the packet core network. However, when MME (Mobility Management ...
