Original place location register HLR preserves the number of all users' CAMEL-Subscription-Information and user place work MSC/VLR, this HLR respectively with MSC POOL in work MSC/VLR be connected with backup MSC/VLR.HLR has disposed the pairing backup MSC/VLR number of MSC POOL simultaneously, if obstructed to the link of the interior work of MSC POOL MSC/VLR in certain exchange process, then sends a message on backup MSC/VLR.
GMSC (gateway mobile switching center) GMSC receive call for ask after, to routing iinformation and the routing call that HLR obtains the user, this GMSC is connected with work MSC/VLR among the MSC POOL.
By NRI, base station controller RNC (or BSC) message that mobile phone is up is routed to correct work MSC/VLR, this RNC respectively with MSC POOL in work MSC/VLR be connected with backup MSC/VLR, a plurality of RNC are generally arranged under the MSC POOL.
Cell phone UE connects by wireless signal between RNC, again with MSC POOL in work MSC/VLR be connected with backup MSC/VLR.
In the IuFlex network system, a MSC POOL is exactly the common service area that similar network element forms.This MSC POOL manages the network element node of its lower floor simultaneously, and a plurality of MSC servers form a MSC POOL.The machine in case work MSC/VLR server is wherein delayed, HLR is according to backup MSC/VLRNUMBER (corresponding relation of the last pre-configured MSC POOL of HLR and backup MSC/VLR NUMBER (provisional roaming number) of configuration, after office direction in MSC POOL is unreachable, just use backup MSC/VLR NUMBER), with backup MSC/VLR obtain carry out mutual.When user's re-accessing network (position renewal, call attempt etc.), RNC, HLR or GMSC etc. are dispensed to backup MSC/VLR among the MSC POOL with active user, MSC/VLRNUMBER in the HLR updating user data is the number of backup MSC/VLR, the user that this MSC server is responsible for can be taken over by the backup MSC among the MSC POOL/VLR at once, guarantee the professional unaffected of user, realized " zero " downtime.
Its operation principle is: work MSC/VLR moves identical software and data simultaneously with backup MSC/VLR, backup MSC/VLR is the mirror image of work MSC/VLR, the signaling link of backup MSC/VLR and ext nal network element HLR/GMSC/RNC is in non-activated state, in case work MSC/VLR breaks down, backup MSC/VLR will activate and be work MSC/VLR, then RNC selects corresponding M SC server in the MSC POOL, realizes the smooth and easy safety guarantee of real-time network truly.
The present invention also provides the MSC/VLR that works among the MSC POOL to delay behind the machine, backup MSC/VLR takes over the machine work MSC/VLR that delays, for the user under the machine work MSC/VLR that delays provides service method, in this method, the cellphone subscriber inserts under work MSC/VLR, and work MSC/VLR is synchronized to backup MSC/VLR with user's IMSI, ISDN and positional information; MSC/VLR delays behind the machine when work, and backup MSC/VLR MSC/VLR that takes over job sends to HLR with user profile, the signaling link of HLR is activated, realize the take over job work of MSC/VLR of backup MSC/VLR, guarantee the professional unaffected of user, realized " zero " downtime.
Yet when the user went wrong in calling and called call business, backup MSC/VLR was different to some extent by the step that the alternative machine work MSC/VLR that delays solves the MSC fault in the IuFlex system, consults Fig. 2 and Fig. 3.
Fig. 2 be in the realization IuFlex system of preferred embodiment of the present invention after the MSC fault user receive the system flow chart of called calling.In the day-to-day operation process, backup MSC/VLR is from synchronous all users' of work MSC/VLR IMSI, ISDN and positional information.Work MSC/VLR delays behind the machine, and backup MSC/VLR substitutes work MSC/VLR, distributes roaming number, and according to the network area distribution calling user of customer location and configuration, inserts the back the user and distribute new TMSI to the user, at last call establishment.After this flow process finished, follow-up business used the new TMSI that backup MSC/VLR distributed to handle at backup MSC/VLR, recovers up to the machine MSC/VLR that delays, and backup MSC/VLR withdraws from service.
Solving the IuFlex network system MSC method that the machine user receives called calling of delaying comprises the steps:
When step 201. work MSC/VLR normally moved, synchronous wherein user's IMSI, ISDN and positional information were to backup MSC/VLR;
The step 202. work MSC/VLR machine of delaying, HLR interrupts to the signaling link of work MSC/VLR, and HLR changes into and is routed to backup MSC/VLR to the message that Provides Roaming Number of work MSC/VLR;
Step 207.GMSC sends initial address message to backup MSC/VLR according to the roaming number routing call;
Step 2010. backup MSC/VLR initiates the heavy allocation flow of TMSI to portable terminal, distributes and has the TMSI of NRI to portable terminal;
Step 2011. backup MSC/VLR sends call setup message to the user;
Step 2012. mobile terminal ring returns ALERTING message, and backup MSC/VLR sends the address and arrives GMSC entirely;
Step 2013. portable terminal off-hook returns connection message, and backup MSC/VLR sends an acknowledgement to GMSC, call through.
Fig. 3 for the MSC/VLR fault of working in the realization IuFlex system of preferred embodiment of the present invention after user's professional system flow chart that makes a call.Originally after the user who inserts under the work MSC/VLR made a call, RNC obtained NRI from the up user message of mobile phone, and the machine because the original corresponding MSC/VLR of NRI has delayed is so RNC routes messages to backup MSC/VLR, by backup MSC/VLR controlling call.Other business of Client-initiated are upgraded as the position, and short message is also observed same principle.After this flow process finishes, because the user has distributed new TMSI,, recover up to the machine MSC/VLR that delays so user's follow-up business is all handled at backup MSC/VLR by new TMSI, backup MSC/VLR withdraws from till the service.
Solving the IuFlex network system work MSC/VLR machine user professional method that makes a call of delaying comprises the steps:
Above-mentioned no matter be user's calling, or during called calling, the MSC in the IuFlex system delays after the machine problem solves, originally the work MSC/VLR of machine of delaying will carry out corresponding fault recovery, again drop into service, backup MSC/VLR then needs to withdraw from service, returns Status of Backups.Therefore, backup MSC/VLR starts the heavy allocation flow of load, and this process is divided into two stages, and the recovery flow process in first stage can be consulted Fig. 4, and the recovery flow process in second stage can be consulted Fig. 5.
Fig. 4 realizes that for the present invention fault MSC/VLR recovers the system flow chart of phase I in the IuFlex system.This stage continues the periodic location update duration of twice, and purpose is to transfer on other MSC/VLR the user who has carried out periodic location update on backup MSC/VLR, and its concrete steps are as follows:
Step 401. sends the heavy assignment commands of load by the maintenance management instrument simultaneously on backup MSC/VLR and RNC, after RNC received this message, the user that just no longer will newly enter MSC POOL was distributed on backup MSC/VLR;
Portable terminal under step 402. backup MSC/VLR carries out the position to be upgraded, and sends position updating request, and RNC is packaged into initial address message and sends to backup MSC/VLR;
Step 403. backup MSC/VLR carries out authentication and encryption to cell phone;
Step 404. backup MSC/VLR sends the heavy assignment commands of TMSI to cell phone, wherein carries non-broadcast location district and empty NRI, sends the position renewal simultaneously and receives cell phone, and cell phone returns TMSI and heavily assigned;
Compare the non-broadcast location district during step 405. cell phone preservation TMSI heavily distributes and the lane place of Cell Broadcast CB, the two difference, so the user uses TMSI to initiate the position renewal again;
Step 406.RNC receives position updating request, because the NRI among the TMSI is empty NRI, so redistribute the work MSC/VLR that this user inserts, this work MSC/VLR is the new work MSC/VLR beyond backup MSC/VLR among the MSC POOL, sends the initial user equipment message to new work MSC/VLR;
The work MSC/VLR that step 407. is new goes up because of user data of no use, thus at first obtain the subscription authentication parameter to HLR, and the user is carried out authentication;
After step 408. authentication was passed through, new work MSC/VLR sent position updating request to HLR, and HLR inserts user data, and home position upgrades and reply, and HLR renewal user's work MSC/VLR number is new work MSC/VLR number;
The work MSC/VLR that step 409. is new encrypts the user;
The work MSC/VLR that step 410. is new sends the heavy assignment commands of TMSI to cell phone, carries the NRI of reposition district and this MSC/VLR, sends the position renewal simultaneously and receives cell phone, and cell phone returns TMSI and heavily assigned.
After the phase I of the heavy allocation flow of backup MSC/VLR load finishes, originally inserted at backup MSC/VLR, and carried out the user that the position is upgraded, all be assigned on other work MSC/VLR, had only that current to carry out professional user last resident at backup MSC/VLR.Thereby second stage is exactly to enable for the heavy assignment problem that solves this part user.
Fig. 5 realizes the system flow chart of fault MSC/VLR recovery second stage in the IuFlex system for the present invention.The concrete steps in this stage are as follows:
The current cell phone that carries out business of step 501. backup MSC/VLR scanning sends the heavy assignment messages of TMSI to these users; Wherein carry non-broadcast location district and empty NRI, these information of user record are returned TMSI and have heavily been assigned;
Step 503.RNC receives position updating request, because NRI wherein is empty NRI, so redistribute the work MSC/VLR that this user inserts, this work MSC/VLR is the new work MSC/VLR beyond backup MSC/VLR among the MSC POOL, sends the initial user equipment message to this new work MSC/VLR;
The work MSC/VLR that step 504. is new does not have user's information, thus obtain user's authentication parameter to HLR, and portable terminal is carried out authentication;
The work MSC/VLR that step 505. is new sends position updating request to HLR, HLR inserts user data to new work MSC/VLR, the current VLR number of upgrade preserving of user, and home position upgrades and replys, the work MSC/VLR number that HLR upgrades the user is new MSC/VLR number;
The work MSC/VLR that step 506. is new encrypts the user;
The work MSC/VLR that step 507. is new distributes new TMSI to give cell phone, wherein comprises the NRI of this MSC/VLR, and the home position renewal receives cell phone.
After second stage finished, all cell phones were transferred to work MSC/VLR from backup MSC/VLR and are inserted, and the inaccessible signaling link to HLR of backup MSC/VLR returns Status of Backups.
Yet, for the present invention, can also adopt other technologies, such as, HLR can be undertaken by Signalling Transfer Point STP to the connection between work MSC/VLR and the backup MSC/VLR; The access base station controller of user UE signal wherein can also be BSC, or RNC and BSC are in same network and deposit use.
In a word, the present invention is not limited to above-mentioned execution mode, anyly is familiar with this operator, without departing from the spirit and scope of the present invention, all should drop within protection scope of the present invention.
