Abstract
The invention discloses a global safe variable synchronized method among 3G mobile network elements, and the procedures are as following: firstly, after an MSCS modifies the global safe variable data, a synchronized command is generated; secondly, after synchronizing the global safe variable data according to the synchronized command, an MGW sends the sync results back to the MSCS; finally, the MSCS sends the sync results of the MGW after being processed back to an OMM which is connected with each other. The technical proposal of the invention raises the synchronization efficiency of the global safe variable synchronized method among the 3G mobile network elements and strengthens the real-time of synchronization.
Description
Technical field
The present invention relates to the control of mobile net elements global safety variable in the 3G mobile communication system, the method for synchronous of global safety variable between especially a kind of 3G mobile net elements.
Background technology
3G (3rd Generation, third generation digital communication) mobile communication system is generally by BSS (Base Station System, base station system) and MSS (Mobile Switching System, mobile switch system) and MS (Mobile Station, the mobile subscriber) form, wherein, MSS generally comprises one or more MSC (Mobile Switching Center, mobile switching centre), one or more VLR (Visitor Location Register, VLR Visitor Location Register).Wherein, MSC is broken down into MSCS (MSC Server, MSC server) and two kinds of network elements of MGW (Media GateWay, media gateway).MSCS and MGW are the relations of one-to-many, and MSCS realizes functions such as call control signalling continues, and realize the effect of Based Intelligent Control, functions such as the carrying of MGW realization resource and access; Thereby 3G network has been realized separating of control and resource.
The global safety variable is kept in the global variable of the professional frame internal memory of single board of mobile net elements, these data owners are relevant with business, for example: system control parameters (bit number ascending state---professional relevant, transmitting terminal MAP (Mantenance Application Part, the maintenance application part) stage is provided with---agreement is relevant etc.), billing parameter (charging way---agreement be correlated with etc.) and authentication etc. whether.The global safety variable is important the whole network control switch that the mobile network runs.
As shown in Figure 1, when the global safety variable data on mobile net elements such as the MSCS changes, adopt the method for synchronous of global safety variable between existing 3G mobile net elements, then need OMM (Operation Maintence Module by linking to each other with other each mobile net elements, operating maintenance module) changes other each mobile net elements relevant parameters respectively, promptly change its relevant parameters by the OMM that links to each other with each MGW.In global safety variable clock source employing mode is example, when changing, the clock source employing mode on the MSCS need carry out when synchronous each MGW gateway, adopt method for synchronous shown in Figure 1, clock source employing mode after the OMM that links to each other with MSCS will change is issued the OMM that links to each other with each MGW, by each OMM corresponding M GW is made amendment respectively again.From above description as can be seen, existing single network element maintenance mode, synchronous efficiency is low, and real-time is poor synchronously.
Summary of the invention
The technical problem to be solved in the present invention provides the method for synchronous of global safety variable between a kind of 3G mobile net elements, has improved the synchronous efficiency of global safety variable between mobile net elements, has strengthened real-time property of synchronizing.
The technical solution adopted for the present invention to solve the technical problems is:
The method for synchronous of global safety variable between a kind of 3G mobile net elements may further comprise the steps:
Generate synchronic command after the data of a, MSCS modification global safety variable;
After b, MGW the data, synchronized result is fed back to described MSCS according to the synchronous described global safety variable of described synchronic command;
C, described MSCS feed back to coupled OMM after the synchronized result of described MGW is handled.
In the such scheme, described step b further may further comprise the steps:
B1, described MSCS send described synchronic command by SCTP (Stream Control Transmission Protocol, SCTP)/described MGW of SIGTRAN (Signaling Transport, signaling transfer protocol) chain road direction;
After b2, described MGW receive described synchronic command, according to the data of the synchronous described global safety variable of described synchronic command;
B3, described MGW feed back to described MSCS with described synchronized result.
In the such scheme, described step a further may further comprise the steps:
A1, with OMM that described MSCS links to each other on revise the data of secure variant;
A2, described OMM arrive described MSCS with the data sync of described secure variant;
A3, if described secure variant is the global safety variable, then described MSCS generates synchronic command.
In the such scheme, if the non-global safety variable of described secure variant then directly finishes synchronous flow process.
In the such scheme, the data of the described synchronic command synchronous described global safety variable of described MGW that to be described MSCS obtain according to intelligent object generate.
In the such scheme, among the described step a2, described OMM is by TCP (Transmission Control Protocol, transmission control protocol)/UDP (User Datagram Protocol, User Datagram Protoco (UDP))/SNMP (Simple Network Management Protocol, Simple Network Management Protocol) communication link with the data sync of described secure variant to described MSCS.
Beneficial effect of the present invention mainly shows: technical scheme provided by the invention has improved the synchronous efficiency of global safety variable between the 3G mobile net elements, strengthened real-time property of synchronizing, stationary problem when having evaded strange land initiation operation, simultaneously, kept compatibility to greatest extent with existing method for synchronous, influence to existing mobile communication system is little, thereby has reduced maintenance cost.
