Description
Technical field
The present invention relates to mobile communication technology, relate in particular to a kind of VLR Visitor Location Register (VisitorsLocation Register, VLR) fault handling method and mobile management net element.
Background technology
Third generation partner program (3rd Generation Partnership Project, 3GPP) be organized in existing Generation Mobile Telecommunication System network (The 2nd Generation, 2G) and 3 G mobile communication network (The 3rd Generation, on basis 3G), released evolved packet system (Evolved PacketSystem, EPS).EPS network comprises evolved universal mobile communication system land radio access web (EvolvedUniversal Mobile Telecommunication System Territorial Radio Access Network, E-UTRAN) and evolution block core net (Evolved Packet Core Network, EPC).Because EPS network is only processed packet switching (Packet Switched, PS) business, therefore current operator adopts original circuit switching (Circuit Switched, CS) territory that CS business is provided.In EPS network, defined the SGs interface between VLR Visitor Location Register (Visitors Location Register, VLR) and Mobility Management Entity (Mobility Management Entity, MME).Wherein, VLR normally closes and is made as same network element with mobile services switching centre (Mobile Services Switching Centre, MSC), is called MSC/VLR, or referred to as VLR.Based on SGs interface function, 3GPP has proposed circuit domain dropping (CS Fallback, CSFB) technology and SGs short message transmission technology (SMS overSGs).CSFB technology makes the subscriber equipment (User Equipment, UE) of E-UTRAN under covering by E-UTRAN, get back to 2G/3G network C S territory finishing service when needs are processed CS speech business to process; SMS over SGs technology allows the UE residing under E-UTRAN reuse the transmission that existing CS territory equipment is realized CS short message.
Reside in E-UTRAN and support CSFB and/or register when the UE of SMS over SGs need to initiate combined registering flow process and is implemented to EPC network PS field and CS network C S territory.In described combined registering flow process, MME need to select one can the MSC/VLR of service is provided and send position updating request to set up SGs association to selected MSC/VLR for UE.SGs association utilizes SCTP (Stream Control Transmission Protocol, the SCTP) service providing of bottom to realize the reliable delivery of SGs interface signaling and business.
Dispose and commercial 2G/3G network in, if operator is at GPRS (General Packet Radio Service, GPRS) support node (Serving GPRS Support Node, SGSN) Gs interface is supported in configuration and between MSC/VLR, resides in 2G/3G network and supports that the UE of PS business and CS business also needs to initiate when combined registering flow process is implemented to the PS territory of 2G/3G network and CS territory to register.In described combined registering flow process, SGSN need to select one can the MSC/VLR of service is provided and send position updating request to set up Gs association to selected MSC/VLR for UE.The service that Gs association utilizes the Signaling System Number 7 link connection of bottom to provide realizes the reliable delivery of Gs interface signaling and business.
After MSC/VLR breaks down, under some scene, such as: the equipment causing because of natural calamity damages, the equipment burnout that short circuit causes, the fault that equipment natural aging causes etc., MSC/VLR cannot reset and restart, and maybe can not automatically reset and restart, and need to wait for after artificial reparation and reset and restart, that is to say can not restart or long-time in can not restart.When MSC/VLR breaks down suddenly and can not restart, or can not restart in long-time time, can cause its associated with SCTP between MME or and SGSN between Signaling System Number 7 bottom link association break.So the SGSN that, has all MME that SGs interface is connected or have Gs interface to connect with this MSC/VLR all can perceive this MSC/VLR can not provide service.But the UE can't proactive notification after MME/SGSN perception registering on this MSC/VLR, causes UE and does not know that registered MSC/VLR can not provide service; The HLR that this MSC/VLR registers simultaneously can not provide service by this MSC/VLR of horse back perception yet, until receive descending CS audio call or short message service.The problem causing is like this that the UE of successful combined registering, after registered MSC/VLR fault, still thinks that it is combined registering before, but but can not receive descending CS audio call or short message service, can not successfully send up short message.This is unacceptable for the user who has no perception, and the customer churn to the complaint of operator and initiation that thereupon produced is also unacceptable concerning operator.
