Abstract
The present invention relates to a method for realizing user calling signalling tracking in a mobile communication system. When a user starts call, and a mobile terminal sends an authentication request to a visit position register, the visit position register leads a responsive message to be carried with a zone bit from which the present invention can judge whether signalling tracking needs to be carried out on the user; subsequently, the signalling tracking zone is transferred into a relevant signaling message along with a calling process; when the calling signalling flows across a module, a program judges whether the user's signalling tracking zone is true; if the user's signalling tracking zone is true, the corresponding signaling message and operation reported by a message body are used for maintaining the terminal. When the method of the present invention is adopted, operators and maintenance persons of the mobile communication system can easily obtain the internal signalling flow path and contents of a mobile user, can rapidly judge the problems encountered in the user's calling process, can solve the failure of the system in the shortest time, and can reduce the loss of the user and the carrier.
Description
(1) technical field
The present invention relates to realize in a kind of PHS communication system the method for user calling signalling tracking, is a kind of efficient real-time method to mobile subscriber's calling signalling tracking in the PHS communication system.By making in this way, the detailed process of PHS mobile subscriber call signaling and content can intactly be shown to terminal, thereby realize the tracking to customer call, be convenient to analyze with navigation system in Call failure, minimum to the system loading influence simultaneously.
(2) background technology
At present, mobile communication technology uses on a large scale, is penetrated in all trades and professions and people's the life.Mobile communcations system is between the moving body, between moving body and the fixed point user, and between fixed point user and the moving body, can set up the communication system of many information transfer channels.Mobile communication comprises collection, processing and the storage etc. of wireless transmission, wire transmission and information.The capital equipment that uses has radio receiving-transmitting unit, switch control device and mobile terminal device.The control switching point (CSP) of mobile communication system is mainly by MSC (mobile switching centre, Mobile Switch Center), HLR (attaching position register, Home Location Register), VLR (VLR Visitor Location Register, Visit LocationRegister), AC (AUC, Aucentication Center) and OMC (operational administrative center, OperateManager Center).In the process that the user calls out, system need carry out the conversion between wired and the wireless protocols, whole calling procedure, and signaling will be through the transmission and the conversion of a plurality of equipment.Equipment disperses often, and same equipment, same software version also has levels and the division of module, and when the customer call problem appearred in beginning, because what use is the released version of not being with Debugging message, the attendant was difficult to orientation problem and goes out in which link.And,, fix a breakdown because the difference of environment, data also differs and finds surely on-the-spot situation need take a long time to enough fault locations usually in the laboratory that can use debug version.And mobile communcations system is a system that real-time is very strong, and it is a system that is entirely customer service, causes system normally to move if break down, even have only very short a period of time, also can cause the discontented of user, influence the service level of operator.So need a kind of method of fault location as early as possible, when meeting accident fault, can in the shortest time, fix a breakdown.The method of signaling tracing has been followed the tracks of signaling in the process of user calling, is reported to webmaster, shows at the centralized operation maintenance interface, and the foundation of fault location is provided for daily maintenance.Traditional signaling tracking method that uses in wired fixed network communication system is, when needs carry out signaling tracing to a user, system is set to this user's unique identification in the resident module of signaling process and user data, when having the user to make a call, systematic comparison user unique identification, when will following the tracks of of being provided with in the sign of finding this user and the module user ID when consistent, this user's call signaling extracted report.This method is not suitable for mobile communcations system, because: one, mobile communcations system is different from wired, user locations is unfixed, when the user roams, the equipment that signaling can be flowed through and much be disperseed, if signaling process is intactly followed the tracks of, adopt broadcast mode that all devices is issued signaling tracing order to certain customer call, on program, can additionally increase a lot of unnecessary processing, if transmission goes wrong, to lose the signaling tracing sign in the certain module, the signaling that then reports is incomplete, can't reach the tracking purpose; Two, in the mobile system, distinct device and module are inconsistent for user's statement, as, some part, user power utilization words number unique identification, some part, use the protocol address unique identification, some part is used the mobile phone logo unique identification, if in each module tracking to certain user is set all, need carry out the conversion of many user ID, simultaneously, grow the compare operation of character string, can have a strong impact on the efficient of system.Three, signaling tracing sign record need issue and be recorded in each module, less stable, and the signaling tracing sign in certain module is lost, and easily causes signaling to report infull situation.
(3) summary of the invention
The signaling tracing mode that adopts in the PHS communication system that provides among the present invention is to add one whether to carry out signaling tracing with recording user in user property.The signaling tracing sign issues with call flow, when user's call flow during to certain module, module only need compare in the signaling with tracking mark, whether just can judge this user needs to carry out signaling tracing.Discarded broadcasting and issued the method for signaling tracing sign, saved the communication resources of system, and the signaling tracing sign of customer call is recorded in the HLR, good stability is difficult for losing; Simultaneously owing to just write down the signaling tracing sign with one, in module to user property relatively the time to the system effectiveness influence not quite.
Technical problem to be solved by this invention is to propose a kind of new method, so that in the PHS communication system, realize tracking to the customer call signaling, be that system only needs the phone number by the user, on the Operation and Maintenance platform, start the signaling tracing order, just can follow the tracks of the detailed interior signaling of user, and the signaling content preserved, with maintenance and the failure location that is used for system.
The main thinking of this method is, adds one and whether the user is carried out signaling tracing with record in user property, and the signaling tracing sign is kept in the HLR (attaching position register).Why the signaling tracing sign being kept at HLR, is because the mobile subscriber calls out the process that authentication is at first arranged, and must arrive first HLR and obtain authentication code and just can make a call.And HLR is general, and what use is to operate in business databases such as ORACLE on the server or SQL SERVER, good stability, and data are difficult for losing.When the user who has been set up the signaling tracing sign begins to call out, the signaling tracing sign issues with call flow, promptly in each signaling interface, add a position, as the signaling tracing sign. when user's call flow arrives certain module, module only need compare in the signaling with tracking mark, whether just can judge this user needs to carry out calling signalling tracking.
The signaling tracing sign is taken in the signaling process, in each bar signaling message, all use a sign to represent whether this signaling is in tracked state exactly, to be HLR be provided with according to the setting of signaling tracing the signaling (generally being authentication message) that is provided with the signaling tracing mark in certain user's the all-calls signaling at first, and the signaling of back then copies from previous signaling and comes.
Background maintenance interface designated user (telephone number, when if No. one two machine is arranged, be defaulted as the mobile subscriber) issue the manmachine command that signaling tracing begins, if telephone number is effective, HLR is changed to the sign that whether carries out signaling tracing in the user property very, and HLR notice VLR Visitor Location Register VLR revises user property.If number is invalid, HLR can return miscue.
During customer call, when portable terminal when VLR Visitor Location Register is sent out authentication request, VLR Visitor Location Register in the message of replying with on this user whether carry out the flag bit of signaling tracing.After, the signaling tracing sign is along with in call flow the is delivered to relevant signaling message, when call signaling certain module of flowing through is that program judges whether this user signaling tracking mark is true, if be true, the operating maintenance terminal that corresponding signaling message and message body are reported then.
The step of the method for realization user calling signalling tracking is as follows in a kind of PHS communication system:
The first step: the input of Operation and Maintenance platform needs the mobile subscriber number of tracking, issues signaling tracing and begins message;
Second step: attaching position register HLR receives the message that begins to follow the tracks of that the Operation and Maintenance platform issues, whether the user who judges input exists, when the input user is inactive users, HLR returns error code, finish this signaling tracing, when the user was validated user, HLR was true with the signaling tracing mark position in this mobile subscriber attribute, the beginning signaling tracing;
The 3rd step: HLR notice VLR Visitor Location Register VLR revises the user property of current mobile user;
The 4th step: when the user when HLR sends authentication request, HLR in return messages with on this user whether carry out the flag bit of signaling tracing, the signaling tracing sign in calling subsequently along with call flow is delivered in all signaling messages;
The 5th step: all signaling tracing signs all have been provided with and have finished, and system is reported to the Operation and Maintenance platform with the interior signaling of process of user calling;
The 6th step: the Operation and Maintenance platform issues the order that stops signaling tracing, and HLR judges input user's validity, when the user is the user who is following the tracks of, the signaling tracing sign that System Cleaning is all, stop this user's calling signalling tracking, otherwise HLR returns error code, signaling tracing is proceeded.
Effect of the present invention is: adopt the method for the invention, make PHS communication system operation and maintenance personnel can obtain mobile subscriber's interior signaling flow process and content easily, judge the problem that runs in the process of user calling, the fault of resolution system in the shortest time rapidly.And this signaling tracking method, just in user property, increased a signaling tracing flag bit, little to the burden influence of system.Adopt this method, can overcome because of the tracking difficulty that user in the PHS communication system moves, equipment disperses, each several part user unique identification method disunity causes, can improve existing systems very easily, systematic cost is little, information is comprehensive, originally the problem that is difficult to location mobile subscriber's Call failure is become simply, can help research and development and maintenance department in the shortest time, to solve fault, reduced the loss of user and operator.
For further specifying above-mentioned purpose of the present invention, design feature and effect, the present invention is described in detail below with reference to accompanying drawing.

(5) embodiment
The present invention is applicable to the user calling signalling tracking of PHS communication system.
Now lift a specific embodiment: the realization of PHS communication system user calling signalling tracking method in the ZXPCS system.
The ZXPCS system is a kind of realization of PHS system (personal handyphone system).The PHS system is a kind of mobile communcations system of ripe development, is the product that a kind of wired access network technology and mobile handoff technique combine from technical system, belongs to the mobile communication product of 2.5G.Along with the development of PHS technology, its data transmission capabilities is close towards the standard of 3G.The signaling process layer of PHS system transmits call signaling by the signaling management layer of open V5 agreement and switch, carries out alternately with subscriber's line signaling and bearer management layer.Signaling Layer software cooperates the Signaling Layer software of bearing bed, database and switch to finish the call control procedure of speech business, control release of speech channel of signaling management layer and continuing of speech channel, and mobile subscriber's speech channel is switched.
Calling subscriber's calling signalling tracking concrete steps are as follows in the ZXPCS system:
The first step: the input of Operation and Maintenance platform needs the mobile subscriber number of tracking, issues signaling tracing and begins message, waits for returning of HLR, and when the input user was inactive users, HLR returned error code, finishes this signaling tracing.When the user was validated user, HLR was true with the signaling tracing mark position in this mobile subscriber attribute, the beginning signaling tracing.
Second step: HLR notice VLR Visitor Location Register is revised the user property of PHS system.
The 3rd step: when calling subscriber's bearing bed when VLR Visitor Location Register is sent out authentication request, VLR Visitor Location Register in the Ev_GetKeyAck that replys (authentication return messages) message with going up the flag bit whether this user carries out signaling tracing.After bearing bed is received this message, judge whether to carry out signaling tracing, if message and the content that the front is not traced into reissued to the signaling tracing process earlier, the signaling tracing process sends to the Operation and Maintenance platform with tracking results, is presented on the terminal interface.
The 4th step: bearing bed is data link layer and bearing bed, and the message of the relevant calling between bearing bed and the VLR Visitor Location Register and message content are transmitted to the signaling tracing process transmitting on the normal call message basis.
The 5th step: whether bearing bed carries out the flag bit of signaling tracing with last user in issuing the PHS_Hookoff of Signaling Layer (off-hook) message.Signaling Layer is judged this sign, if carry out signaling tracing, the message and the message content of relevant calling between ensuing bearing bed and Signaling Layer is issued the signaling tracing process.
The 6th the step: all signaling tracing signs all have been provided with and have finished, system with the V5 signaling of process of user calling and Q.931 signaling be reported to the Operation and Maintenance platform.
The 7th step: the Operation and Maintenance platform issues the order that stops signaling tracing, and HLR judges input user's validity, when the user is the user who is following the tracks of, all signaling tracing signs are known by system, stop this user's calling signalling tracking, otherwise HLR returns error code, signaling tracing is proceeded.
The user does when called, and step is similar, and just the usertracking sign of Signaling Layer is that it obtains when database is looked into the customer location district.Signaling Layer brings bearing bed with RingingEvent (ring) message with tracking mark.
When switching, Signaling Layer has kept user's tracking mark, and the bearing bed of reposition obtains user's tracking mark once more from the authentication message of VLR Visitor Location Register is returned.
Referring to Fig. 1, Fig. 1 begins (stopping) flow chart for PHS communication system user calling signalling tracking.
Operation and Maintenance platform OMC issues signaling tracing (tracking user's telephone number) beginning message to HLR, after HLR receives message, judge input user's validity, if the input user is already present validated user, then with (HLR in the user property of relative users, VLR) signaling tracing sign is changed to very, begins the input user signaling is followed the tracks of.If the input user does not exist, then return error message, stop this signaling tracing setting.
Operation and Maintenance platform OMC issues signaling tracing (tracking user's telephone number) and stops message to HLR, after HLR receives message, judge input user's validity, if the input user is masked as very for already present validated user and the present signaling tracing of this user, then the signaling tracing sign in the user property of relative users is changed to vacation, stops this signaling tracing.If the input user does not exist, then return error message, stop this signaling tracing and stop to be provided with.
Referring to Fig. 2, Fig. 2 is PHS communication system user calling signalling tracking customer call signaling report flow figure.
The customer call signaling reports process in the calling procedure of indicating among the figure.When a user begins to call out, send authentication message to HLR; HLR adds the user signaling tracking mark in the authentication message of returning; After flow process in the signaling tracing sign with the call flow transmission.When this user's call flow is flowed through some modules, signaling tracing flag bit in the user property of this module verification input, if be true, then on the basis of carrying out the normal call flow process with detailed signaling message report to the Operation and Maintenance platform, and continuation call flow, if be false, then continue call flow, do not carry out reporting of call signaling.
Referring to Fig. 3, Fig. 3 is the calling subscriber of a ZXPCS system calling signalling tracking sequential chart.
Shown user's all signaling message when doing caller among the figure.The signaling tracing sign passes to bearing bed by EV_GetKeyAck (authentication return messages) message, and bearing bed is delivered to Signaling Layer by PHSHookOff (off-hook) message with the signaling tracing sign again.Bearing bed is received the EV_GetKeyAck message of database, has 3 message not trace into before, and they are Setup (link setup) message, CallPreeding (calling out beginning) message and EV_GetKey (authentication) message.When bearing bed knows that this user need carry out signaling tracing, when reporting EV_GetKeyAck message, can be with three information reportings that do not report in the past.
Referring to Fig. 4, Fig. 4 is the called subscriber of a ZXPCS system calling signalling tracking sequential chart.
Shown among the figure that the user is doing signaling messages all when called.The signaling tracing sign passes to Signaling Layer by EV_SendUserLocation (transmission location area information) message, and Signaling Layer is delivered to bearing bed by RingingEvent (paging) message with the signaling tracing sign again.Signaling Layer is received the EV_SendUserLocation message of database, has 1 message not trace into before, is EV_QueryUserLocation (request customer position information) message.Know this user when Signaling Layer and need carry out signaling tracing, when reporting EV_SendUserLocation message, can be with the information reporting that does not report in the past.
Referring to Fig. 5, the message time sequence figure that Fig. 5 switches for the ZXPCS system.
PHS user might produce switching in moving process, this moment, the signaling tracing sign also needed to transmit, and can both report to guarantee all signalings.The signaling tracing sign passes to bearing bed by EV_GetKeyAck message from database during switching.This moment, the signaling tracing sign of Signaling Layer did not change, and two message Setup (beep-page message), EV_GetKey (authentication) that bearing bed will receive before the signaling tracing sign are reported to operating maintenance terminal with EV_GetKeyAck message.
Referring to Fig. 6, Fig. 6 is the terminal displayed map of the signaling tracking method used in the ZXPCS system.
This figure uses signaling tracking method in the ZXPCS system, and when the user was carried out signaling tracing, the signaling tracked results that system reports was in the demonstration of operating maintenance terminal.
