Description
Technical field
The present invention relates to digital SPC exchange tandem exchange field, particularly the user data synchronization technology of double tandem office.
Background technology
The end office (EO) of existing communication network network operation, type is various, and some type is aging, and producer no longer safeguards.The tenability of their business is poor, can not satisfy user's demand.And end office's user data management dispersion, the operation cost of operator is increased.
If thoroughly change this situation, can opposite end office transform, but cost be too high.If realize the centralized management of opposite end office's user data in tandem exchange, can reduce the requirement of opposite end office, prolong the vitality of end office (EO), utilize less investment just can reach: user data is concentrated management, professional triggering is flexible, and the service logic relation is convenient to control etc.
Because existing tandem exchange possesses access register (VLR) function, can and home location register (HLR) carry out alternately, thereby synchronizing user data.Therefore general user data with end office (EO) is put on the HLR, and the function of access only plays in end office (EO), and the corresponding relation of record number and subscribers feeder no longer manages user data.All callings are handled by tandem exchange all to tandem exchange.Tandem exchange analyzes the number of receiving, calls out or carries out service log-on to HLR.
Work finely when this mode only is connected with a tandem exchange in end office (EO), still, in the existing communication network, in order to improve the reliability of tandem exchange, generally adopt double tandem office.That is to say in same tandem aspect and build two tandem exchanges, the route data basically identical, end office (EO) is linked into two tandem exchanges simultaneously, and end office (EO) is to the all-calls of tandem aspect, through the calling of tandem exchange, all adopt mode polling between two tandem exchanges of load sharing to end office (EO).This moment, user data need to leave in two tandem exchanges, for so that user when calling out through any one tandem exchange, the flow processs such as call authority is judged, professional triggering are finished unanimously, do not give the sensation of user's differentiation, need data to guarantee that synchronously the user data of two remittance interoffices is in full accord.
Summary of the invention
The technical problem to be solved in the present invention is the stationary problem of user data in the digital SPC exchange double tandem office, realizes the double tandem office user data consistence.
Technical scheme of the present invention is, in the system that comprises attaching position register, tandem exchange and access end office (EO), to (the Mobile Application Part of MAP in the No.7 signalling system between the tandem exchange, MAP) expand, increase the data sync operation, when making tandem exchange's user data in the double tandem office system change, another one also can change synchronously, if the failure of the user data update of one of them tandem exchange, the user data of another one tandem exchange also should be failed.Simultaneous operation comprises that the position type synchronously such as upgrades, inserts, deletes, cancels.
Wherein, described sync bit method for updating is:
3.1 the terminal use is to the registration of work tandem exchange, work tandem exchange sends " position updating request " to user place attaching position register,
3.2 attaching position register sends " insertion position renewal request of data " to work tandem exchange;
3.3 it is local that work tandem exchange inserts the user position update data; If the user position update data are inserted failure, directly return the insertion position to attaching position register and upgrade data failure and upgrade failure to terminal use's home position; Insert successfully if described user position update data are local, then carry out next step;
3.4 work tandem exchange will send data simultaneously operating request to backup tandem exchange, action type is " position renewal ",
3.5 after backup receiving request of tandem exchange " position renewal " the simultaneously operating request, user data is inserted into this locality, then to the whether success message of tandem exchange's return of working;
3.6 if work tandem exchange receives that backup tandem exchange upgrades failed message, then remove local data and return the insertion position to attaching position register and upgrade data failure and upgrade failed message to terminal use's home position; If receive the message that backup tandem exchange position is updated successfully, then return more new data and be updated successfully message to terminal use's home position of insertion position to attaching position register; Attaching position register will be write down the positional information after the renewal.
The method of described synchronous data inserting is:
The terminal use's who writes down when 4.1 attaching position register upgrades according to the position positional information, send " data inserting " message to work tandem exchange, local user data is at first revised by work tandem exchange, if local data is revised failure, directly return " data inserting failure " message to attaching position register; If this locality is successfully modified, then put user data " unreliable " sign, and send data simultaneously operating request to backup tandem exchange, action type is " insertion ", and etc. the response of tandem exchange to be backed up;
4.2 after backup receiving request of tandem exchange " insertion " the simultaneously operating request, will revise local user data, then to the whether success message of tandem exchange's return of working;
4.3 if backup tandem exchange returns success message, work tandem exchange is set on "reliable" sign user data, return the Update Table success to attaching position register simultaneously, if backup tandem exchange returns failed message, then return the Update Table failure to attaching position register.
In the method for described synchronous data inserting, if synchronously data inserting failure, the user makes a call, and enters work tandem exchange or backup tandem exchange;
If 5.1 enter work tandem exchange, will trigger " recovery " operation, namely again obtain data from attaching position register; Attaching position register inserts data in the work tandem exchange again, and work tandem exchange is with data backed up in synchronization tandem exchange; The synchronously again failure that " if recovery " operation triggers, this calling of this user will be failed, and the calling of initiating from work tandem exchange next time continues to trigger " recovery " operation;
If 5.2 enter backup tandem exchange, with the data of using before revising.
The method of described synchronous deleted data is:
6.1 the terminal use's who writes down when attaching position register upgrades according to the position positional information sends " deletion user data " message to work tandem exchange, local user data is at first revised by work tandem exchange; If local data is revised failure, directly return " failure of deletion user data " message to attaching position register; If this locality is successfully modified, then put user data " unreliable " sign, and send the data synchronization request operation to backup tandem exchange, action type is " deletion ", and etc. the response of tandem exchange to be backed up;
6.2 after backup receiving request of tandem exchange " deletion " the simultaneously operating request, will revise local user data, then to the whether success message of tandem exchange's return of working;
6.3 if backup tandem exchange returns success message, work tandem exchange is set on "reliable" sign user data, return the Update Table success to attaching position register simultaneously, if backup tandem exchange returns failed message, then return the Update Table failure to attaching position register.
The described method of cancelling the position synchronously is:
7.1 the terminal use's who writes down when attaching position register upgrades according to the position positional information sends " cancelling position requests " message to work tandem exchange, work tandem exchange sends the synchronization request operation to backup tandem exchange, and etc. the response of tandem exchange to be backed up;
7.2 after the simultaneously operating request " is cancelled " in the request of receiving of backup tandem exchange, user data is deleted from this locality, is returned to work tandem exchange then and whether successfully to cancel;
7.3 if work tandem exchange receives that backup tandem exchange returns success message, then delete local user data, return undo success message to attaching position register, return failed message if receive backup tandem exchange, then return to attaching position register and cancel failure.
The described method of cancelling the position synchronously can also for:
8.1 the terminal use sends de-registration request to work tandem exchange;
8.2 work tandem exchange before this user data of deletion, initiates the data synchronization request operation to backup tandem exchange earlier;
8.3 after backup tandem exchange receives, judge that wheel synchronization type is " cancelling ", with local data user deletion, return to work tandem exchange then;
8.4 work tandem exchange receives that backup tandem exchange returns undo success to the terminal use when returning successfully, returns failure if receive backup tandem exchange, then recovers local data and fails to terminal use's return.
The present invention has effectively solved the stationary problem of user data in the digital SPC exchange double tandem office system, realizes the double tandem office user data consistence.So that the user is when any one tandem exchange, the flow processs such as call authority is judged, professional triggerings are finished unanimously, to the sensation of user's differentiation.

Embodiment
As Fig. 1 is a kind of double tandem office system configuration schematic diagram that has end office (EO).Comprised in the whole system with the lower part: have the MAP signaling link between MAP signaling link, MS and the MS between ISUP (ISDN USER PART is the User Part of isdn signaling) signaling link, MS and the HLR between access end office (EO) (LS), stored-program control exchange tandem exchange (MS), attaching position register (HLR), LS and the MS.In native system, be connected, be connected by standard MAP signaling with attaching position register by the ISUP signaling between programme-controlled exchange tandem exchange and the end office (EO), the MAP signaling protocol by expansion between the tandem exchange connects.Whole data synchronization process is finished by the MAP signaling process software control of tandem exchange.
Tandem exchange's user data backup can be unit with the office, same tandem exchange is fixing to be standby office with another one tandem exchange, can also be unit with PSID (Personal Station Identifier travelling carriage identifier), a backup of each PSID configuration tandem exchange.Shown in Figure 1 is to be that unit carries out user data synchronization with the office.
MAP signaling between MS and MS is expanded, increased the data sync operation, realization is synchronous to user data.Expanded data simultaneous operation, parameter have wheel synchronization type, simultaneous user's sign, synchrodata, synchronized result etc., and wherein wheel synchronization type is divided into the position and type synchronously such as upgrades, inserts, deletes, cancels.
Fig. 2 is various data manipulation data synchronous flow journey figure of the present invention to Fig. 5;
(1) Fig. 2 is that the synchronous flow process of flow data is upgraded in the position
Terminal use A is to the work MS1 of tandem exchange registration, MS1 sends " position updating request " to user A place attaching position register HLR, can upgrade the position after HLR judges, sends " insertion position renewal request of data " to MS1, after MS1 receives, the user position update data are inserted local.If local data inserts failure, directly upgrade failure to the HLR home position.
If local the insertion successfully judges that this user needs synchronously, then will send the data synchronization request operation to the backup MS2 of tandem exchange, action type is " position renewal ", and waits for the response of MS2.
After the MS2 request of receiving " position renewal " the simultaneously operating request, user data is inserted into this locality, then whether successful to MS1 return.
MS1 receives that the response of MS2 judges later on, if backup tandem exchange position is upgraded successfully, then upgrades successfully to the HLR home position, if fail then remove local data and fail to the renewal of HLR home position.
HLR receives after the position renewal success message of MS1, will write down the positional information of MS1.
(2) Fig. 3 and Fig. 4 are the synchronous flow processs that user data inserts and deletes
At first consider to increase from HLR the CAMEL-Subscription-Information of terminal use A.The positional information of the A that HLR writes down when upgrading according to the position sends " insertion data " message to MS1, and MS1 at first revises local user data.If local data is revised failure, directly return " data inserting failure " message to HLR.
If this locality is successfully modified, will put and judge that this user needs synchronously, then to put user data " unreliable " sign, and send the data synchronization request operation to the backup MS2 of tandem exchange, action type is " insertion ", and waits for the response of MS2.
After the MS2 request of receiving " insertion " the simultaneously operating request, will revise local user data, then whether successful to MS1 return.
Work tandem exchange is judged, if backup tandem exchange returns success, then user data is set on "reliable" sign, and returns the Update Table success to HLR simultaneously, if failure then return the Update Table failure to HLR.After the failure, the user makes a call, and may enter MS1 or MS2.
A: enter MS1.Owing to do not remove " unreliable " mark, therefore, if next time, user A made a call from MS1, MS1 will trigger " recovery " operation, namely again obtain data from HLR.HLR inserts data among the MS1 again, and MS1 again can be with the synchronous MS2 of data.Guarantee that the user uses new data this moment.The synchronously again failure that " if recovery " operation triggers, this calling of this user will be failed.The calling of initiating from MS1 next time continues to trigger " recovery " operation.
B: enter MS2.With the data of using before revising.
Consider again from HLR deletion user's relevant CAMEL-Subscription-Information.The positional information of the A that HLR writes down when upgrading according to the position sends " deletion user data " message to MS1, and MS1 at first revises local user data.If local data is revised failure, directly return " failure of deletion user data " message to HLR.Later the same surface analysis of flow process similar just will " insertions " operates and changes " deletion " into and operate.
Consider that again the user revises CAMEL-Subscription-Information by terminal.The user initiates " insertion user data " operation to certain tandem exchange (being assumed to MS1), and MS1 sends message to HLR.HLR judges and can revise, sends " insertion user data " or " deletion user data ", later operation and top similar to MS1.
(3) Fig. 5 is a HLR position destruction operation data sync flow process
When user A moved, HLR need to cancel the positional information operation.According to existing procedure, the positional information of the A that HLR writes down when upgrading according to the position sends " cancelling position requests " message to MS1, and MS1 judges that this user needs synchronously, at first sends the synchronization request operation to the backup MS2 of tandem exchange, and waits for the response of MS2.
After the simultaneously operating request " is cancelled " in the request of receiving of backup tandem exchange, user data is deleted from this locality, returned to MS1 then and whether successfully to cancel.
MS1 judges, if MS2 returns success, then deletes local user data, returns undo success to HLR, if failure then return to HLR and to cancel failure.
HLR receives the MS1 success response, continues more new technological process of position, inserts user data, if receive the MS1 failure response, failure is upgraded in the position.
User A also can break away from network by cancelling binding, and send de-registration request to MS1 this moment.MS1 is before this user data of deletion, initiate the data synchronization request operation to MS2 earlier, after MS2 receives, judge that wheel synchronization type is " cancelling ", with local data user deletion, return to MS1 then, when MS2 returns successfully, MS1 returns undo success to user A, if failure MS1 recovers local data and fails to user A return.
