Problems solved by technology

However, when MME (MobilityManagementEntity, mobile management entity) switching occurs, SG-W (Serving-GateWay, serving gateway) and PGW (PacketDataNetwork-GateWay, packet data network gateway) will create, update and delete users due to MME switching The resource fails, causing the UE to fail to create, update and delete resources in a short period of time

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 TargetMME and the resource processing temporary rejection message responded by the SourceMME;

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

[0058] In this embodiment, since the SourceMME and the ...

Abstract

The invention discloses an optimization method for resource processing of an SGW (Serving-GateWay). The method comprises the following steps: when the position of UE (User Equipment) is changed, receiving a handover request message sent by a Target MME (Mobility Management Entity) and a source processing temporary reject message responded by a Source MME; processing the handover request message, and replying handover success response to the Target MME; when the Source MME and the Target MME complete UE resource handover, sending a resource processing request message to the Target MME, and performing resource processing after receiving a resource processing success message responded by the Target MME. The method can guarantee creation, update and deletion success of UE resources during MME handover of the UE.

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-nternet Protocol, Internet Protocol) proposed by 3GPP (3rdGenerationPartnershipProject, Third Generation Partnership Project), which builds an open and flexible The 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 the packet switching technology. The existing specifications about UE's access to IP network through EPS, such as 3GPPTS23.401 and 3GPPTS29.274, etc. already have signaling and process descriptions for handover of UE in the packet core network. However, when MME (Mo...
