Description

A kind of signaling tracking method and system

Technical field

The present invention relates in the communication network to the treatment technology of signaling particularly a kind of signaling tracking method and system.

Background technology

Signaling tracing (Signaling Trace) is critical function in the communication network operation maintenance, by the signaling tracing message between the track record Telecommunication network equipment, the signaling tracing Message Record that takes place in the network element (Network Element) is got off, for the operation maintenance personnel carry out the signaling process analysis and fault location provides important means.Described network element is device nodes such as the control, service, resource in the communication network, and signaling tracing message is carried out between these nodes alternately, coordinates each device node of control and finishes telecommunication services such as voice call jointly.

Carrying out signaling tracing can be undertaken by user ID, also can be undertaken by interface identifier, and wherein the signaling tracing that is undertaken by user ID both can carry out on single network element node, also can carry out by inter-network element.When on single network element node, carrying out, because signaling tracing is confined to the Signalling exchange information on a certain network element node, can not allow the operation maintenance personnel understand the Signalling exchange situation that this user is taken place at the whole network in telecommunication service process such as voice call, and the operation maintenance personnel more need to be appreciated that the signaling traffic flow process situation of this user in whole communication network usually, and end-to-end signaling tracking means that therefore we can say inter-network element are the trend of WeiLai Technology development.

Can realize the inter-network element signaling tracing by signaling network in the prior art, such as the inter-network element signaling tracking method of realizing signaling tracing by hardware mode, this method is duplicated the signaling link between each network element by the special hardware device, carry out the signaling link that duplicates out multiplexing again, and converge and focus on some local backs and converging the signaling tracing instrument that articulates hardware on the concentrated link, realize that with this inter-network element follows the tracks of.The shortcoming of this method is: need to increase hardware unit, and need the extra physics signaling link of traction to converge the construction cost height specially; Signaling Analyzer is a hardware instruments, and price is expensive, further increases construction cost; And when operating terminal and signaling tracing instrument are one, be unfavorable for that many people operate simultaneously.

Realize the inter-network element signaling tracing by signaling network, a kind of imagination is also arranged at present, promptly realize the inter-network element signaling tracing by the expanded signalling agreement.No matter somewhere the expanded signalling agreement can be to revise the Signalling exchange flow process, allows the signaling that takes place in the calling procedure,, can both be transmitted back on the concentrated point.Such as IP multimedia type families system (IMS, IP Multimedia Subsystem) SIP (SIP in, SessionInitiation Protocol) signaling process, no matter where the user roams into, relevant signaling all must be transmitted back on the service call conversation control function (S-CSCF).The expanded signalling agreement also can be: additional data expense on signaling protocol, the each point of Signalling exchange all records the signaling information that this point takes place in the additional accessing cost for data, so that when any some tracking signaling, can both know and the relevant former interaction flow of institute's tracking signaling, thus the signaling tracing of realization inter-network element.The shortcoming that realizes the inter-network element signaling tracking method by the expanded signalling agreement is: expanded signalling protocol impact face is big, realizes not too easily; Increase signaling consumption, cost can be very high, and is difficult during practical application.

Step 401: client sends the signaling tracing request to the access module of Centroid or the access module of fringe node, comprises in the signaling tracing request: the sign that follow the tracks of the user.

When client is initiated the end-to-end signaling tracking of inter-network element usually, the user ID that input need be followed the tracks of, and determine that following the tracks of type is the end-to-end tracking of inter-network element, initiate the signaling tracing request then, and start reporting of window wait signaling tracing message.

Client can comprise following steps to the access module of Centroid or the access module transmission signaling tracing request of fringe node in the step 401:

Client sends log-on message to the access module of Centroid or the access module of fringe node, comprises in the log-on message: login name, Centroid domain name; The access module of Centroid or the access module of fringe node are carried out the legal information of authentication acquisition login name according to the Centroid domain name with the security module that log messages is forwarded to Centroid; The access module of Centroid or the access module of fringe node are to the information of client transmission authentication success, and client shows the interface that inter-network element the whole network is followed the tracks of; Client sends the signaling tracing request by the access module of Centroid or the access module of fringe node to the tracking module of Centroid, comprises in the signaling tracing request: follow the tracks of user's sign, can also comprise: follow the tracks of type of service.When carrying out the inter-network element signaling tracing, described tracking type of service is that inter-network element is followed the tracks of business.

Step 402: after the access module of Centroid or the access module of fringe node receive the signaling tracing request of client transmission, the signaling tracing request is forwarded to the tracking module of Centroid.

During practical application, client can have various ways:

A kind of form is that client form and purposes are bound, such as: the universe administrative client that can initiate the whole network and be the inter-network element signaling tracing can only be logined at Centroid, if login successfully, then can be used for the whole network and follows the tracks of; Can only initiate the local client of local signaling tracing can login at Centroid, also can login at fringe node, but after logining successfully, only carry out in the Centroid or the local trace in the fringe node, not the function of universe tracking.Universe client under this form is called the peculiar unit of Centroid at present embodiment.Universe client and local client are distinguished by software setting.

Another kind of form is that universe administrative client and local client can be an entity, and the signaling tracking interface that will be showed by the decision of login form.Wherein, if client is logined with the central field user, then no matter this client is the access module login from Centroid, still login from the access module of fringe node, logging request is all gone authentication by the safety management module that access module is forwarded to Centroid, after the authentication success, client shows universe management function interface, the universe management function comprises the whole network following function in the interface.After client is logined with the central field user, the module that all service request that client is initiated all can be forwarded to by the access module of access node in the business unit of Centroid is handled, such as: after the access module of the access module of Centroid or fringe node sent the signaling tracing request, described signaling tracing request will be transmitted to the tracking module of Centroid with the client of central field user login.If client is to login with the local domain user, the access module that logging request will be logged node is forwarded to the safety management module authentication of logining node, after the authentication success, local trace is only carried out at client shows local management function interface, local management function interface.Client is with after the local domain user login, and the access module that all service request that client is initiated will be access in node is forwarded to the resume module in the business unit of self node.Client in second kind of form is called other unit that are free on outside Centroid and the fringe node in the present embodiment.Described central field user is the user name that comprises the central field sign, described local domain user is the user name that does not comprise any sign or comprise the local domain sign, such as: tom@sys or tom@center can be the central field users, because contain central field sign @sys Huo @center etc. in the user name, and tom or tom@local can be the local domain users, because do not have domain identifier in the user name or comprise local domain sign @local.

Described step 401 and step 402 are clients when being other unit that are free on outside Centroid and the fringe node, and client sends the process of signaling tracing request to the tracking module of Centroid.

When client is the distinctive unit of Centroid, client to the tracking module of Centroid send the signaling tracing request process can for: be the client login Centroid of universe client and login successfully by software setting; Described client sends the signaling tracing request by the access module of Centroid to the tracking module of Centroid, comprises in the signaling tracing request: the sign that follow the tracks of the user.
