The present invention provides one paging combining method.
Description
The invention belongs to communication technical field, especially design a kind of optimization using method of paging channel, it can make full use of channel resource, guarantees that paging information is handed down to travelling carriage quickly and accurately.
Paging procedure is an important procedure in the mobile communication, and relevant agreement proposes in ETSI (ETSI) standard.
Usually, in the mobile communication system that comprises a base station controller (BSC), a plurality of base transceiver station (BTS), a mobile switching centre (MSC) and a plurality of travelling carriage (MS), when calling out the MSC that Danone finds the user for one, MSC determines the lane place of mobile station login, and all BSC by this lane place control distributing paging (PAGING) message then.The identity that contains calling user in the message is determined the IMSI (international mobile logo) of paging subchannel and the sub-district table of necessary transmission beep-page message.BTS receives after the paging command (PAGINGCOMMAND) that BSC issues, and page queue is put in the paging application, and then with certain merging dispatching method, several different paging applications are merged and issues.In view of the characteristics of digital mobile communication system wireless transmission, when transmission quality lacks perfection, need take certain retransmission mechanism to guarantee to provide the service of appropriate mass to the user.Therefore in general, a beep-page message should only not sent out in a sub-district.Which equipment providing retransmission mechanism as for, agreement is not clearly stipulated, can select MSC, can select BTS yet.BTS provides retransmission mechanism that certain superiority is arranged, because BTS knows the behaviour in service of PAGCH (paging and access grant channel) resource, it can be optimized it; Meaningless repeating transmission was still carried out in many sub-districts when MSC provided retransmission mechanism then can avoid travelling carriage successfully to insert, because it will wait for the regular hour when application is retransmitted, and BTS and BSC can not connect replying with paging of travelling carriage.
The optimization operational version that the purpose of this invention is to provide a kind of paging channel, it can effectively be dispatched channel, preferably base station retransmission mechanism and mobile switching centre's retransmission mechanism are combined, very effectively utilize limited channel resource, realized that the optimization of Radio Resource is used to guarantee that paging information issues fast.
The invention provides a kind of paging channel of using and optimize using method in the mobile communication system that comprises base station controller, base station, mobile switching centre, travelling carriage, the base station adopts dispatching method to handle for paging block, comprising following steps:
Paging first is used to send assignation information; Carry out assignment immediately according to sending assignation information;
Retransmit paging according to judged result to assignation information immediately; According to the judged result of retransmitting paging is sent empty paging.
Provided by the invention to the processing of paging block in the step of dispatching method, better be to carry out in the following manner:
Send assignment message in reserved block, wherein access channel (AGCH) formation is granted in scanning earlier, and issues Radio Interface Layer 3 (RIL3) immediate assignment message that number is no more than access permission reserved block number (BS AG BLKS RES);
Scan paging group one by one, wherein scan the super group of paging N earlier, N=0..BS_PA_MFRMS scans the super group of paging N+1 during next the execution, so that can be with individual super full scan one time of organizing of BS_PA_MFRMS in the time of BS_PA_MFRMS multi-frame;
And judge whether to exist the paging item, if judged result be "Yes" and have paging Xiang Erqi number deficiency first, then retransmit the paging item and supply, these paging items merged in the corresponding RIL3 paging request message issue; If judged result is a "No", then scan the AGCH formation of this CCCH channel once more, only issue a RIL3 immediate assignment message;
On if the piece of this paging group correspondence is also of no use, then scan this paging group once more, and look for the paging item of a plurality of pagings by a first-in first-out principle and a merging method, merge to then in the RIL paging request and issue; On if the piece of this paging group correspondence is also of no use, then on this sky paging information, send empty paging.
The present invention also provides a kind of paging merging method, use in its repeating transmission paging step in can described in the above paging channel optimization method, it comprises step: if having continuous 4 paging requests and their mobile identifier to be the temporarily moved subscriber identification number in certain paging group formation, then these 4 paging requests are merged into a RIL3-RR (radio resource) message paging request type 3; If have continuous 2 paging requests and their mobile identifier to be the temporarily moved subscriber identification number in this paging group formation, then these 2 paging requests are merged into a RIL3-RR message-paging request type 2 together with subsequently a paging request; In other situation, one or two continuous paging requests are merged into a RIL3-RR message one paging request type 1.
In addition, described in the above paging channel is optimized in the using method, and reasonable for the life cycle that guarantees any one paging item, the number of times of transmission that all will retransmit the paging item when CCCH scheduling each time adds 1, and the scope that exceeds the OM setting just abandons it.
Fig. 1 is the schematic flow diagram of the dispatching method of paging according to an embodiment of the invention that uses in mobile communication system;
Fig. 2 shows a kind of according to an embodiment of the invention schematic diagram of paging merging method.
Also in conjunction with the embodiments technical scheme of the present invention is done a detailed description with reference to Fig. 1 and Fig. 2 below.
Fig. 1 shows the schematic flow diagram of the paging dispatching method of the embodiments of the invention that use in mobile communication system.Wherein per 51 multi-frames of CCCH (Common Control Channel) message scheduler task are carried out once.This flow process comprises step: at first carry out system initialization; In reserved block, send assignment message then, wherein first scan A GCH (permission access channel) formation, and issue RIL3 (Radio Interface Layer 3) immediate assignment message that number is no more than BS AG BLKS RES (insert and allow the reserved block number), that is, send assignation information (step S1) in reserved block;
Then, scan the paging resistance one by one, wherein at first scan the super group of paging N (N=0..BS_PA_MFRMS, the super group of scanning paging N+1 when carry out next time like this can be with BS_PA_MFRMS super group full scan one time in the time of the individual multi-frame of BS_PA_MFRMS (frame number between identical paging)) (step S2);
Then judge whether to exist the paging item, its process is called when scanning certain page queue M of the super group of paging N, several that take out this paging group queue heads by first-in first-out (FIFO) principle and paging merging methodological principle not paging the paging item and judge (step S3); If if the judged result of step 3 is a "Yes", promptly there is paging Xiang Erqi number deficiency first, then flow process enters next step and gets and retransmit the paging item and supply, and then, these paging items is merged in the corresponding RIL3 paging request message issue (step S5); If the judged result of step 3 is a "No", then flow process enters a following other step, if promptly there is not the paging item of not paging among this page queue M, then scan the AGCH formation of this CCCH channel once more, at most only issue a RIL3 immediate assignment message (step S4) specifically.Then carry out the judgement (step S6) of sky paging block; If the piece of this paging group correspondence still be of no use on, then carry out calling retransmission step (step S7), promptly, scan paging group M once more, be to merge methodological principle (a kind of merging method that will describe in detail as the back) by FIFO principle and a kind of paging to look for the paging item of several pagings specifically, merge to then in the RIL3 paging request and issue.If the piece of this paging group correspondence still be of no use on, BTS will send empty beep-page message by the requirement of agreement on this paging block, and process ends.
Fig. 2 shows the flow chart of a kind of paging merging solution of the embodiment of the invention, and this flow process is following carrying out: at first carry out system initialization; From page queue, take out N＜=4 a paging item then; And the mobile logo number (MSID) of 4 paging items differentiated, if have continuous 4 paging requests and their mobile identifier to be TMSI (temporarily moved subscriber identification number) in certain paging group formation, then these 4 paging requests are merged into RIL3-RR message paging (request) type 3, and finish this flow process; If have continuous 2 paging requests and their mobile identifier to be TMSI in this paging group formation, then these 2 paging requests are merged into a RIL3-RR message-paging (request) type 2 together with subsequently a paging request (if present, no matter its MS Id is TMSI or IMSI); Other situation is merged into a RIL3-RR message-paging (request) Class1 with one or two continuous paging requests.
Such a case may appear in the priority orders based on above-mentioned paging channel is used, and certain exists paging request for a long time to issue once more, and this moment, travelling carriage discharged channel already.This will inevitably increase the weight of system burden.Therefore, when CCCH scheduling each time, the number of times of transmission that we will retransmit the paging item adds 1, and the scope that exceeds OM (Operation and Maintenance) setting just abandons it.All added 1 owing to sent number of times during each the scheduling, so when calling retransmission, we do not upgrade the number of times of transmission of retransmitting the paging item.So both can guarantee enough repeating transmission number of times, and be unlikely to allow same paging item in formation, exist long-time again meaninglessly.
Scheme provided by the invention is handled by the priority orders of paging first-assignment immediately-repeating transmission paging-empty paging certain paging block with dispatching method, has improved the utilance of descending CCCH channel to greatest extent.
