A circuit switching cs service processing method, device and network system

Abstract

A method, device and network system for Circuit Switched (CS) service handling are provided in the present invention, which relates to the field of communications, ensures success of Circuit Switched (CS) voice calls, and improves user conversation experience. The method includes: a first mobile management network element receives service indication information sent by a second mobile management network element after the second mobile management network element is restarted, said second mobile management network element being associated with Idle mode Signaling Reduction (ISR); the first mobile management network element sends a detach request message to a user equipment (UE), said detach request message being used for requesting the UE to carry out combined location updating, and the detach type of the detach request message being International Mobile Subscriber Identification (IMSI) detach; the first mobile management network element receives a combined location update request message sent by the UE when the UE performs the combined location updating, and initiates a Circuit Switch (CS) domain location update process. The present invention is used for restarting the core network nodes.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and network system for circuit switching CS service processing. Background technique [0002] Evolved Packet System (EPS for short) is the third generation partnership project (3rd Generation Partnership Project, 3GPP for short) in the second generation (The Second Generation, 2G for short) mobile communication network GSM / EDGE (Global System of Mobile Communication / Enhanced DataRate for GSM Evolution, Global System for Mobile Communications / Enhanced Data Rate GSM Evolution Technology) and the third generation (The Third Generation, referred to as 3G) mobile communication network UMTS (Universal MobileTelecommunications System, universal mobile communication system) of. The EPS network includes an Evolved Universal Mobile Telecommunications System Territorial Radio Access Network (Evolved Universal Mobile Telecommunication System Territorial Radio Access Netwo...

Problems solved by technology

Because the current UE resides on the 2G / 3G network, the MME will not receive the paging response from the UE. At the same time, because the SGSN resets and restarts, the SGSN will not page the UE after receiving the paging instruction, which eventually leads to the termination of the MSC / VLR SGs interface paging, resulting in call delay or even failure

[0007] In short, when the ISR is activated, whether it is after the reset and restart of the MME associated with the ISR or the reset and restart of the SGSN associated with the ISR, it will eventually cause the MSC / VLR to terminate the paging of the SGs interface, resulting in call delay or even failure.
