AI Technical Summary

Problems solved by technology

If the new MME / SGSN does not support the PFH function, then the S-GW or P-GW cannot update the corresponding associated FQ-CSID, which will cause the S-GW or P-GW to fail to correctly release the PDN connection corresponding to the corresponding FQ-CSID

Embodiment 2

[0097] exist Figure 5 In the illustrated embodiment, when the new MME determines that the old MME supports the PFH function during the context transfer process, it sends the context confirmation message carrying its own PFH capability information to the old MME. Image 6 Shown is the second embodiment in which the synchronization method for partial fault handling is applied to the actual TAU process, which mainly includes the following steps:

[0098] Step 601, the UE moves to a new TA list area, sends a tracking area update request to the new MME, and requests to register in the new area, and the request message carries the GUTI allocated to the UE by the old MME.

[0099] Step 602, the new MME finds the old MME according to the GUTI identifier, sends a context request signaling to perform a context acquisition process, and carries information about the PFH capability of the new MME itself (whether it supports the PFH function) in the context request signaling.

Abstract

Synchronization method for Partial Failure Handling (PFH), which includes the following steps: when a User Equipment (UE) moves to a new Mobility Management Entity (MME), the new MME sends the PFH capability information of itself to the original MME in the context delivery procedure; when the original MME determines, according to the received PFH capability information, that the new MME does not support the PFH function, it initiates an association and synchronization operation for the PFH to the Service Gateway (S-GW) and the Packet data network Gateway (P-GW). The present invention also discloses a synchronization system for PFH, which enables the S-GW or the P-GW to synchronize the Packet Date Network (PDN) connection associated with the Fully Qualified PDN Connection Set Identity (FQ-CSID), thus allowing correct release of the PDN connection resources corresponding to the S-GW or the P-GW.

Description

technical field [0001] The invention relates to fault processing technology in the communication field, in particular to a synchronization method and system for partial fault processing. Background technique [0002] With the sudden emergence of World Interoperability for Microwave Access (WiMax, World Interoperability for MicrowaveAccess) technology, the third-generation mobile communication system must improve its network performance and reduce network construction and operation costs in order to maintain its competitiveness in the mobile communication field. Therefore, the standardization working group of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) is currently working on researching a packet switching core network (PS Core, Packet Switch Core) and a global system for mobile communication radio access network (UTRAN, Evolution of Universal Mobile Telecommunication System Radio AccessNetwork). The research topic is called System Archi...
