Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with specific embodiment.
The embodiment of the invention mainly is to carry out prioritization by the registration message to the user, and when the user of obliterated data registered in VLR, VLR earlier sent the high registration message of priority to HLR by D interface, alleviates impact to D interface with this; Further, the user of obliterated data does when called in VLR, and by each user data of users of backup before resetting at VLR, VLR preferentially uses the positional information of backup to alleviate impact to the channel of eating dishes without rice or wine.
At first, the structure of VLR provided by the present invention is done detailed description, as shown in Figure 1, Fig. 1 is the VLR structural representation.Its structure comprises following a few part:
Service Processing Module 101: be used to receive the register requirement of the user of visit VLR to the VLR transmission, and register requirement is sent to order module 102, according to the ranking results of order module 102, preferentially send the high registration message of priority to HLR then by D interface with HLR; Also be further used for judging and HLR between D interface flow excess load whether, after determining excess load, carries out described register requirement is sent to order module 102, after definite not excess load, directly register requirement is sent to HLR.
Order module 102: the registration message that receives is carried out prioritization, and with prioritization result notification Service Processing Module.
More preferably, this VLR also comprises:
Backup module 103: with user data backup externally on the memory device; Read the user data that backs up on the memory device externally, the user data that is read is sent to Service Processing Module 101.
VLR database 104: the user data of depositing the called subscriber of the visit VLR that Service Processing Module 101 recovers.
Below the concrete implementing procedure of this method is done detailed description.
When VLR obtained user data, the user need carry out this user's registration.For example VLR owing to the upgrading, fault is restarted or other reason cause reset after, VLR loses user data, when losing this VLR of user visiting of user data in VLR, need carry out this user's registration.The embodiment flow process of register method provided by the present invention as shown in Figure 2, this method mainly contains following a few step:
After step 201:VLR resetted, the user who visits this VLR sent register requirement to VLR.
Carry out not needing to send register requirement when some is professional the user, but the user who visits this VLR directly registers to VLR.
Wherein, this user's data not among the VLR recited above.
Step 202: judge whether excess load of D interface flow; If, execution in step 203; If not, execution in step 204.
Judge described in this step the D interface flow whether can be judged by VLR by excess load, for example the Service Processing Module in the first embodiment of the invention; Independent device also can be set to be judged.
Step 203: when registration, the registration message that receives is carried out prioritization, first to the high registration message of HLR transmission priority according to the VLR as a result of prioritization by D interface, thus make location registration process level and smooth, process ends.
In this step, VLR sends the high registration message of priority to HLR earlier by D interface, and then, according to the flow system flow situation, the back sends the low registration message of priority to HLR, does not perhaps send the low registration message of priority.
In step 201, step 202 and the step 203 of the invention described above method that embodiment provides, can realize by some concrete devices, with the VLR device that first embodiment of the invention was provided is example, send the high registration message of priority to HLR earlier by D interface, the back sends the low registration message of priority to HLR and can be finished by Service Processing Module 101, in the step 203 registration message is carried out prioritization and can be finished by order module 102.
Recited above to registration message carry out prioritization generally be according to the registration parameter come registration message is carried out prioritization.
Wherein, the registration parameter can comprise: registration type and front position district parameter etc.
In this step, when according to the registration type of registration in the parameter registration message being carried out prioritization, it is the highest that the registration hiding message in the time of will carrying out business is made as priority, and it is minimum that other periodic registration message is made as priority.
In this step, when according to the front position district parameter of registration in the parameter registration message being carried out prioritization, it is the highest that new Internet user's registration message is made as priority, and it is minimum that other registration message is made as priority.Wherein, when judging whether,, be new Internet user often if not then illustrating by judging whether front position district parameter is the lane place that this MSC/VLR covers to new Internet user.
Step 204: register according to normal register flow path, need in registration process, not carry out prioritization to registration message.
In the described method flow of Fig. 2, whether the flow of at first having judged D interface before registration message is carried out prioritization excess load, also can not carry out the judgement of step 202, whether excess load is not all carried out the ordering of priority to guard system, and VLR sends the high registration message of priority to HLR earlier by D interface then.
If visiting the user of this VLR does called, after VLR resets, VLR receives visiting this VLR user's calling, VLR receives that to this called subscriber's distributing paging VLR is restoring user data from HLR after this called subscriber's the page response, at this moment, if the D interface excess load with HLR then continues flow process described in Fig. 2, the method that sorts by the priority to registration message is alleviated the impact to the D mouth.
Above-mentioned is by registration the user who visits VLR, VLR obtains the method flow of user data, further, the user of visit VLR does when called, because lost this user's data among the VLR, cause the message traffic surge of open paging channel easily, so consider that at this user may do the method for the VLR restore data when called.
Its flow process as shown in Figure 3, its method has following steps:
Step 301: before VLR resets, user data is backed up.
The user data of wherein said backup can only comprise: identifying information, positional information and other paging necessary information; Also can comprise all reset before user data among the VLR.
These user data can back up in switching equipment with the form of database, also can back up in hard disk or other External memory equipment.
This step can be finished by the backup module among the VLR 103.
Step 302:VLR is after resetting, and the user of visit VLR does when called, and call proceeding is to VLR.
At this moment, the data that do not have this called subscriber among the described VLR.
Step 303:VLR is according to the called subscriber's positional information in the user data of backup, to called subscriber's distributing paging.
In this step, the called subscriber's positional information in the user data can be carried out reading and sending by backup module 103 and be carried out issuing of called subscriber's paging for Service Processing Module 101.
After step 304:VLR receives called subscriber's page response, promptly in the VLR scope, find this called subscriber and this called subscriber's paging receiving after, VLR uses the user data of backup to recover called subscriber's user data; If do not receive called subscriber's page response, then VLR does not need user data is recovered.
If user data backup is in switching equipment, then VLR extracts the user data that user data recovers the called subscriber from switching equipment; If user data backup is on hard disk, then VLR extracts the user data that user data recovers the called subscriber from hard disk; If user data backup is on other External memory equipment, then VLR extracts the user data that user data recovers the called subscriber from other External memory equipment.
In addition, VLR checks that the backup user data is free restriction, in the several hrs of general recommendations after VLR resets, just need not check after promptly most of user has surfed the Net again.
In this step, Service Processing Module 101 is carried out the process of the user data that recovers called subscribers, and the called subscriber's that recovered user data is left in the VLR database.
In the described method flow of Fig. 3, VLR also can use the user data restoring user data of backup earlier, then according to positional information to user's distributing paging.
Further, after VLR resets, VLR can recover user's partial data earlier according to backed up data, positional information etc. for example, VLR receives after the calling of visiting this VLR user then, to this called subscriber's distributing paging, receive this called subscriber's page response after, recover other data of this user again according to backed up data.
In addition, VLR can not do when called the user yet, initiatively recovers user's data.For example, in the traffic ebb stage, the user does not do calledly, and at this moment, VLR can initiatively carry out the recovery of user data, can recover to HLR, also can recover by the user data of backup.
In above two embodiment, if resetting, VLR belongs to active behavior, as system upgrade or artificial reset etc., then on time point, should be chosen in the traffic ebb stage, and also the stage of traffic ebb in follow-up several hrs as far as possible, as morning, between the user that can guarantee like this to shut down in a large number started shooting in the morning, the user that do not shut down surfed the Net by periodically registering.
As seen from the above, the present invention is by the user during in caller, in registration process, registration message is carried out prioritization, the registration earlier that priority is high, the post-registration that priority is low, further, by backing up each user data of users, the preferential positional information restoring user data of using backup when called, the impact that when alleviating VLR and obtain user data system is caused with this.
