Description
Technical field
The present invention relates to wireless communication field, relate in particular to the method that in WCDMA mobile communcations system and the GSM mobile communcations system periodical position renewing timer (T3212) duration is provided with.
Background technology
In PCS Personal Communications System, system need know the change in location of mobile station MS and record in the database, provides correct routing iinformation for going into to call out.Adopt the WAP (wireless access point) of two-layer centralized data base mode recording user in the existing mobile communication system: the number of the VLR Visitor Location Register (VLR) at attaching position register (HLR) store home user's CAMEL-Subscription-Information and the current place of user; The CAMEL-Subscription-Information copy of VLR storage visitor and current lane place (LA) information.When customer position information changed, the user can initiate more new technological process of position, reports latest position information to VLR, and upgraded relevant location information in the HLR database by the VLR start flow when needed.
But HLR might break down, make it database some be damaged.Though database can recover from Backup Data, the data recovered storehouse is not up-to-date situation, and the renewal that takes place between backup and the fault has just been lost the last time.In this case, to depend on the wireless access that enlivens of MS be that MS initiates out calling or enter new lane place trigger position to upgrade in the recovery of HLR database positional information.Reside in same position for a long time or rarely have the calling of going out to take place as if MS, system can cause going in a large number the call failure generation because the meeting recovery time of database location information is long so.
Therefore prevailing system has defined the periodic location update of MS, guarantees the positional information upper limit of recovery time by the regular wireless contact initiatively of MS.Except the customer position information data were recovered this function, periodic location update also had another critical function in addition.
System can not in time grasp state of user in some cases, as:
(1) user mobile phone automatic power down.
(2) user enters the blind area.
(3) the user when system sends the IMSI detach message because the wireless channel transmission quality is relatively poor, error rate height can not correctly be deciphered system.
When running into above-mentioned situation, system thinks that also the user is in attachment state in a very long time, perhaps in the end in the sub-district of registration.In this case, can waste the part Radio Resource and carry out invalid paging for going into calling system.For fear of this situation, system needs the method for the off-grid of finding the user.In prevailing system, it is the effective means of current discovery user off-grid that recessive shutdown is used in combination with periodic location update.If user's registration message is not received by system within a certain period of time, in the VLR of user registration, be released state just with user ID, be defaulted as user's shutdown.The duration of the T3212 of system is set to less than latent separation duration like this, if the user was related with system before latent separation timer expiry, and the reclocking of latent separation timer.When the latent timer expiry that separates, just can judge user's off-grid.
In service at existing network, the duration of T3212 and latent separation length of timer are the important parameters that influences mobile network property.On actual the setting, require the duration of T3212 to separate length of timer less than concealing, though the duration of T3212 is provided with the too short service performance that can promote network in general in addition, but can make the network signal flow increase greatly, reduce utilization ratio of wireless resources, shorten the average stand-by time of MS; Latent separation timer is provided with excessive, can make system can't in time find the off-grid user, causes waste of radio resources.Therefore the network operator need adjust this two length of timer meticulously according to actual conditions, just can make systematic function reach more excellent.
The duration of current T3212 disposes at base station controller (BSC) in gsm system, and sends MS in the system message of each Cell Broadcast CB, as shown in Figure 1.The WCDMA system similarly.
This method that the T3212 duration is set at BSC, can make troubles in following situation in actual use:
1. after HLR broke down, because the duration of T3212 guarantees the positional information upper limit of recovery time, operator just need reduce the duration of T3212 if wish to recover user's latest position information in the short period of time.According to present method, network operator need be reset the duration of T3212 on the webmaster of a plurality of BSC, and after thinking that HLR has recovered user's latest position information, recovers the duration of original T3212 again in the webmaster of a plurality of BSC.The operation more complicated.
2. find a certain regional signaling traffic when network operator and increase that VLR loads when excessive, need to increase the duration of T3212, to reduce the load of VLR.This moment, the duration of T3212 was revised the latent length of timer of separating of the system that need consider simultaneously, though in order to avoid user's start occurs and normally thought that by system the situation of off-grid occurs with system communication.But T3212 disposes in the webmaster of BSC at present, and the latent length of timer of separating disposes in the webmaster of VLR, and the cooperation of these two timers goes wrong easily.
