Description
Technical field
The present invention relates to the mobile communication technology field, particularly improve the method and the device of inter-system paging success rate in CDMA (Code Division MultipleAccess, code division multiple access) 2000 network systems.
Background technology
Inter-system paging is at two or more MSC (mobile switchcenter in the CDMA2000 network, mobile switching centre) is the place of circuit domain core network element adjacency, in order to improve paging success rate, in paging, the method for two or more MSC paging simultaneously.Generally when realizing inter-system paging, all can carry out repeatedly paging, promptly paging failure for the first time carries out the paging second time again.The MSC that the MSC of user's initial registration is called service MSC and its adjacency is called in abutting connection with MSC, has user position information on the service MSC, can find in abutting connection with MSC according to positional information.Inter-system paging is that service MSC initiates, and in service MSC paging, finds the information in abutting connection with MSC according to positional information, initiates inter-system paging to adjacency MSC.
When carrying out inter-system paging, have following a kind of particular case: the user begins to register on service MSC, because the user is on the border of two MSC, the user begins to register to adjacency MSC, suppose just in time during this time to initiate paging, because the user registers impossible paging success.When the user be registered in go up in abutting connection with MSC after, according to the agreement regulation, HLR (Home Location Register, attaching position register) finds that the MSC of user's registration has changed, will be to former registration MSC, promptly serve MSC and send out registration and cancel message RegCancel.At this moment paging for the first time is overtime, because the user is registered in now on MSC, at this moment can initiate inter-system paging to adjacency MSC as crossing, so paging to probability be very big, but because the customer position information of service MSC is deleted, can't find in abutting connection with MSC according to positional information, so can't initiate paging to adjacency MSC, paging has just been failed probably like this.This kind particular case is the situation of a kind of paging and registration conflict.
A kind of existing solution is, in the paging first time, if service MSC receives RegCancel message, illustrate that the user has registered from another one MSC, to keep user position information and not delete, in paging next time, will initiate paging like this to adjacency MSC.But a problem of Cun Zaiing is like this, will be very complicated for the retention position management of information.
Referring to Fig. 1, the detailed process of inter-system paging is as follows when paging and registration conflict in the CDMA2000 communication system
Step S101: service MSC sends out beep-page message Page to its BSC (base station controller, base station controller);
Step S102: service MSC sends out inter-system paging message ISPage2 to border MSC; Meanwhile, mobile phone is initiated location update message LocUpd from border MSC;
Step S103: border MSC initiates beep-page message Page to its BSC;
Step S104: border MSC is that attaching position register is initiated registration message RetNot to HLR;
Step S105:HLR sends out registration cancellation message RegCancel to service MSC;
Step S106: service MSC returns registration cancellation success message regcancel (Success) to HLR;
Step S107:HLR returns registration success message retnot (Success) to border MSC;
Step S108: border MSC puts renewal success message locupd (success) for its BSC return;
Step S109: at this moment paging is overtime;
Step S110: service MSC sends out paging for the second time to its BSC.Because at this moment mobile phone is deleted in the positional information of service MSC, so can't find border MSC and initiate inter-system paging to border MSC.
From said process as can be seen, when key was paging for the second time, the user had been registered in border MSC and has gone up, if can initiate inter-system paging to border MSC, paging probability of successful at this moment should be very big.But because mobile phone is deleted in the positional information of service MSC, so can't initiate inter-system paging to border MSC.
For addressing this problem, existing at present a kind of realization technology is after registration on the MSC of border, still to preserve user's information such as position at mobile phone on service MSC.But this processing method is to the location information management of the preserving more complicated of getting up.
