It can effectively increase the paging success rate of the boundary region in mobile exchange center range by changing the region range of paging the mobile terminal; and succeeds in solving the problem that mobile terminal makes frequent register in the boundary region in the mobile exchange center range by setting the boundary region parameters of the mobile terminal.
Description
Technical field
The present invention relates to the paging technique in the wireless communication system, be meant the method for wireless boundary region problem in a kind of solution code division multiple access (CDMA) communication system mobile switching centre scope especially.
Background technology
The borderline region of wireless communication system tends to exist a lot of problems because signal changes complicatedly, and mainly have two problems at the borderline region of cdma communication system: frequent location registers and border paging success rate are low.
Borderline region can be divided into two kinds: a kind of is the interior borderline region of mobile switching centre (MSC) scope; Another kind is the borderline region between MSC.Each MSC administers a plurality of lane place (LAC), and LAC is meant that portable terminal can move arbitrarily and do not need to carry out the zone of location registers, and the borderline region of each LAC is exactly the borderline region in the MSC scope, also can be called the borderline region of MSC.Borderline region between the LAC of different MS C administration is exactly the borderline region between MSC.
Portable terminal in the cdma communication system is searched for the strongest pilot channel signal continuously on the frequency of current distribution, when portable terminal searched new pilot channel signal than the strong 3dB of old pilot channel signal in the time period of self determining, the idle switching took place in portable terminal.Portable terminal judges whether registration area (REG_ZONE) changes after carrying out the free time switching, if portable terminal is determined to carry out location registers; Otherwise portable terminal determines not need to carry out location registers.Portable terminal is after determining to carry out location registers, determine when to its system message that issues according to base station sub-system (BSS) again and carry out location registers, the final location registers of determining roughly has dual mode, and a kind of is location registers mode immediately, and promptly portable terminal carries out location registers immediately; A kind of is the delay position pattern register, and promptly in laggard line position registration of the time period that BSS sets, for example BSS sets 1 minute, and then portable terminal carries out location registers carrying out the free time switching after 1 minute.
Under the situation of the borderline region jitter in cdma communication system MSC scope, and when the registration area of portable terminal changes, if BSS is configured to location registers mode immediately, portable terminal will frequently carry out location registers, cause the cdma communication system message congestion; Because the frequent location registers of portable terminal will reduce the called paging success rate of portable terminal greatly.If BSS is configured to the delay position pattern register, then in the time period of setting, the calling of in the Anchor MSC scope portable terminal being initiated does not have the phenomenon of response with called paging occurring.
Fig. 1 shows MSC scope inner boundary area schematic, as shown in Figure 1, same MSC administration LAC1 and LAC2, borderline region 101 and borderline region 102 have been formed the borderline region in the MSC scope, be positioned at the intersection of borderline region 101 and borderline region 102 when portable terminal, because the borderline region jitter, portable terminal can frequently carry out location registers.If portable terminal is positioned at borderline region 102, and in LAC1, carried out location registers, when LAC1 carries out paging to portable terminal, may can't paging arrive portable terminal, so the paging success rate on the MSC scope inner boundary zone has been very low at all.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of method that solves the wireless boundary region problem, effectively improve the paging success rate in mobile switching centre scope inner boundary zone, and successfully solved portable terminal carries out frequent location registers in mobile switching centre scope inner boundary zone problem.

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 accompanying drawing.
During A interface paging portable terminal on MSC, two kinds of paging modes are arranged usually, a kind of is paging in the scope of sub-district (CI), and another kind is paging in the LAC scope.Because portable terminal may not carry out location registers after carrying out the free time switching between CI, caused the mobile terminal data of storage in the MSC/ Visited Location Registor (VLR) inaccurate often, the mode of paging in the therefore general employing LAC scope.
When portable terminal is positioned at the borderline region of MSC scope, generally speaking often paging less than, therefore in the present invention, adopt the method that changes the paging domain scope, promptly portable terminal is carried out paging, improve the paging success rate in MSC scope inner boundary zone in LAC main region and borderline region scope.
Fig. 2 shows and changes paging domain scope schematic diagram, as shown in Figure 2, same MSC administration LAC1 and LAC2, the overlapping part of LAC1 and LAC2 is the borderline region in the MSC scope.For the portable terminal called paging, the borderline region in the definition MSC scope is LAC12, and LAC12 is the virtual location district; The LAC of the part that overlaps is the LAC main region, and promptly the do not overlap zone of part of LAC1 and LAC2 is the LAC1 main region, and LAC2 and the LAC1 zone partly that do not overlap is the LAC2 main region.Because what dispose among the original BSS is LAC1 or the interior data of LAC2 scope, after making BSS receive paging request in the LAC12 scope, can correctly handle portable terminal, need in BSS, dispose the data of the borderline region in the MSC scope, be the data of LAC12, the sub-district that comprises of LAC12 for example, so that after the base station controller among the BSS (BSC) is received paging request to portable terminal, this paging request can be sent to relevant base station transceiver station (BTS), finally complete successfully paging portable terminal.
In addition, the definition in virtual location district is diversified, more than description only is a kind of definition mode wherein, also the overlap-add region of definable LAC main region and LAC borderline region is the virtual location district, when LAC comprises a plurality of borderline region, can be set to each independent borderline region that LAC comprises in the virtual location district, or the virtual location district is set to the set of whole borderline regions that LAC comprises, or the virtual location district directly is set to the overlapping portion of whole borderline regions that the LAC main region comprises with it.
Fig. 3 shows MSC and changes paging domain scope flow chart, and as shown in Figure 3, the processing procedure that MSC changes the paging domain scope may further comprise the steps:
Step 303:MSC to portable terminal, finishes the paging to portable terminal with current call proceeding.
Step 304:MSC carries out paging to portable terminal after changing the paging domain scope once more.MSC is a virtual location district scope to the regional extent that portable terminal carries out paging once more, or is the overlap-add region scope in LAC main region and virtual location district.
In addition, MSC also can directly carry out paging to portable terminal in the overlap-add region scope in LAC main region and virtual location district.By the method for above change paging domain scope, can effectively improve the paging success rate in MSC scope inner boundary zone.
When if the paging channel message traffic is big in the LAC scope, MSC can be set at virtual location district scope to the regional extent that portable terminal carries out paging once more; If the paging channel message traffic hour in the LAC scope, MSC can directly be set at the regional extent of portable terminal being carried out paging the overlap-add region scope in LAC main region and virtual location district; When if the paging channel message traffic is moderate in the LAC scope, the regional extent that MSC carries out paging to portable terminal once more can be set at the overlap-add region scope in LAC main region and virtual location district.
As shown in Figure 2, MSC judges in LAC1 main region scope whether success of the paging of portable terminal, if success, with current call proceeding to portable terminal; Otherwise MSC carries out paging to portable terminal in the LAC12 scope, or MSC carries out paging to portable terminal in the overlap-add region scope of LAC1 main region and LAC12.Correspondingly, MSC judges whether the paging to portable terminal is successful in the LAC2 scope, if success, current calling continues; Otherwise MSC carries out paging to portable terminal in the LAC12 scope, or MSC carries out paging to portable terminal in the overlap-add region scope of LAC2 main region and LAC12.In addition, MSC also can directly carry out paging to portable terminal in the overlap-add region scope of LAC1 main region and LAC12; Correspondingly, MSC also can directly carry out paging to portable terminal in the overlap-add region scope of LAC2 main region and LAC12.
If all there is the borderline region in the MSC scope lane place and a plurality of lane place, promptly comprise a plurality of virtual locations district in a LAC scope, and when the geofence that MSC carries out paging to portable terminal once more is virtual location district scope, then MSC will carry out a paging to portable terminal in each virtual location district scope, until completing successfully, or portable terminal was carried out a paging until each the virtual location district scope in the LAC scope to the portable terminal paging.At this moment, if the virtual location district is set to the overlapping portion of whole borderline regions that the LAC main region comprises with it, then MSC only needs carry out a paging to portable terminal.
Overall area number (TOTAL_ZONE) in the portable terminal borderline region parameter is set to 2, zone time, (ZONE_TIME) was set to 5～10 minutes, like this under the unsettled situation of MSC scope inner boundary regional signal, portable terminal switches to LAC2 by LAC1, switch to LAC1 again, just can not initiate location registers immediately, portable terminal is just initiated location registers behind the timer expiry by the time, has therefore effectively avoided the generation of frequent location registers phenomenon.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
