Description

A kind of signaling tracking method

Technical field

The present invention relates to moving communicating field, relate in particular to that a kind of have can be by the signaling tracking method of call-index (being CALL TRACE function) to trace information.

Background technology

Message tracking function in the mobile communication system be a kind of in practical operation and maintenance process very important function., orientation problem on-the-spot for record has very important effect.When mobile communication system is applied to commercial environment, wish the bigger effect of message tracking function performance, analyze to carry out network adjustment and optimization, ubiquitous problem in the large scale call under the understanding commercial environment such as being used to collect data.Therefore requiring message to follow the tracks of can break through on the original basis, the information of metered call process as often as possible, and rapid screening as required.

At present, carry out message and follow the tracks of the following three kinds of methods of mainly taking:

1, based on the signaling tracking method of standard interface

This method is followed the tracks of standard agreement message all on the specified interface by specify certain criteria interface (for example u interface of WCDMA system, IUR interface, UU interface, IUB interface) when creating tracing task.Accept or when sending a signaling message of following the tracks of interface, copy an informational message, send a copy to the message tracker, and show and preservation at the message tracker.

This method can be followed the tracks of the mass data of certain interface within a certain period of time.Be fit under the actual environment all ordinary calls be caught at the bulk information of this interface.But do not possess CALL TRACE function, can't find quickly and easily when noting abnormalities message and other interface messages that this unusual calling is associated take place, only be adapted at writing down the scene to a certain extent, and the application on orientation problem has very big limitation.And it is single to analyze gimmick, is difficult to by other analysis means.

2, based on calling party's message tracing method

When following the tracks of, this method need the user ID of designated call (as IMSI:International MobileSubscriber Identity; IMSI International Mobile Subscriber Identity).Accept or send one when relating to user signaling message to be tracked, copy a signaling message, send a copy to the message tracker, and show and preservation at the message tracker.

This method only is fit to the tracking of designated user, must provide the user ID of this designated call before following the tracks of earlier.Can only the user who appoint be followed the tracks of, the result of tracking can't be used for the analysis of network communication quality.

3, based on the message tracing method of signaling tracing instrument

This method can be followed the tracks of the message of each interface in the communication system by some signaling tracing instrument, and can carry out CALL TRACE.For example the signaling tracing instrument MA10 of gsm system can follow the tracks of the message of each interface of gsm system, and CALL TRACE function is arranged.

Before use signaling instrument is followed the tracks of, the signaling instrument must be connected on each interface of communication system, just can catch the message on these interfaces.In the process that connects the signaling instrument, need to interrupt the connection of these interfaces inevitably, cause communicating interrupt.And the signaling instrument is generally comparatively expensive.

Summary of the invention

The present invention proposes a kind of trace information can be may further comprise the steps by the signaling tracking method of call-index:

A: in the message tracker, create the message tracing task, the Selective Incoming Call condition of following the tracks of is set;

B: after radio network controller tracking execution body receives this tracing task, the calling that inserts is judged,, and carried the call identification of determining described calling simultaneously if satisfying described filtercondition then sends to the message tracker with the message of this calling;

C: the message tracker shows in real time the tracking message that receives and call identification and saves as the tracking results file, discerns simultaneously and indicates exceptional signaling.

According to said method of the present invention, comprise the steps: that also described message tracker under off-line state, carries out index and ordering according to call identification to the message of preserving in this document, make all information centralized displaying of same calling.

According to said method of the present invention, also comprise the steps: described message tracker screening and gather the exceptional signaling that indicates, and determine respective call according to the pairing call identification of exceptional signaling.

According to said method of the present invention, described call identification is UTRAN Radio Network Temporary Identifier (UTRAN Radio Network Temporary Identity:U-RNTI).

According to said method of the present invention, described tracking Selective Incoming Call condition is the standard interface of selected tracking.

According to said method of the present invention, described tracking Selective Incoming Call condition is the call coverage of selected tracking.

According to said method of the present invention, described tracking Selective Incoming Call condition is the call business of selected tracking.

According to said method of the present invention, described tracking Selective Incoming Call condition is to set the continuous time of tracking or the maximum number of calls of tracking.

According to said method of the present invention, send among the described step B and also carry timestamp sign, the veneer sign of handling current message and/or message direction sign in the tracking message of message tracker.

Method of the present invention can be followed the tracks of all signalings of certain several standard interface in certain time period, and CALL TRACE is provided function.As the message that in the message that traces into, notes abnormalities, use CALL TRACE function to call out review to unexpected message, find all relevant signalings of this calling, carry out the abnormal cause analysis again, solve the problem that exists, improve the network quality of communication system.

Method of the present invention both had been applicable to RNC (the Radio Network Controller of WCDMA system, radio network controller), also be applicable to the network element that has similar position with RNC in the mobile communcations system, CBSC (centralized base-station controller) of the BSC of gsm system (Base Station Controller, base station controller), cdma system etc. for example.

Description of drawings

Fig. 1 is the inventive method flow chart.

Embodiment

Below in conjunction with accompanying drawing method of the present invention is further elaborated.

With reference to flow chart shown in Figure 1, at first be positioned at tracing task of establishment on the message tracker of operation maintenance center, be provided with as required and follow the tracks of the filtercondition of calling out.

Can follow the tracks of all protocol messages of standard interface, perhaps only follow the tracks of all protocol messages of some or several standard interfaces, but also specify message type is further dwindled the tracking message scope.As for the WCDMA system, can select to follow the tracks of four standard interface message such as IU, IUB, IUR, UU, also can select only to follow the tracks of the message of one of them or several interfaces.

Can define the call coverage of following the tracks of as required.Such as, the condition that is provided with is only followed the tracks of the calling that inserts from some sub-district, and for example, only follow the tracks of and satisfy certain professional qualification, with the WCDMA system is example, can select to follow the tracks of interactive service, professional, the background service of stream, one or several business in the session service or the calling of service parameter.This point can be provided with flexibly according to existing technology, dwindles following range as required in a large amount of the calling.

Owing to started the tracking of total interface message in the communication system, a large amount of interface tracking information reportings must be arranged, for guaranteeing that these message that report can not influence the call handling process of communication system, need the time of restriction Continuous Tracking or the number of calls of following the tracks of simultaneously, and when message traffic is excessive, in time start flow control.

After RNC receives tracing task, the calling that inserts is judged that for the calling of satisfying filtercondition, then the message copying portion with this calling sends to the message tracker, carry the specific identifier of this calling simultaneously, this sign can unique numbering of determining this calling.As the U-RNTI in the WCDMA system (UTRANRadio Network Temporary Identity, UTRAN Radio Network Temporary Identifier).Also can carry other supplementary as required,, handle the veneer sign of this message, information such as message direction as timestamp.

Information and specific identifier that the message tracker will be called out show in real time, and are kept in the tracking results file.Discern and identify exceptional signaling simultaneously, use blue the demonstration as the message of normal flow, and the message of unusual flow process is used red display.Perhaps the not isolabeling with other makes a distinction unexpected message with normal messages.

Under off-line state, the message tracker is analyzed according to the trace information of preserving, and according to the call identification of calling out the message of preserving in this document is carried out index and ordering, makes all information centralized displaying of same calling.The message tracker can also screen under off-line state and gather the exceptional signaling that identifies, and demonstrates the pairing call identification of each exceptional signaling simultaneously.
