See also Fig. 1, when being called out, certain PS (makes a general reference all called type business, comprise voice, note is submitted, missed call prompting (Missing Call) etc.), (SETUP) message that connects at first is broadcast to CSC and the CS under the current PA, and all CS that belong to current PA then send on paging channel (Paging) broadcasted in the paging of this PS.After the called PS response, letter the present afterwards transmits in point-to-point mode between PS and network.At high telephone traffic region, a large amount of beep-page messages makes paging channel become the main bottleneck of restriction system capacity.
Chinese patent discloses a kind of cellular communication system No. 93105317, and this system sends the paging request to the locating area of the last registration of desired mobile station, and described locating area comprises more than one cell.If do not receive response, then send the paging request to the paging domain that comprises a plurality of locating areas that may find this mobile radio station, and needn't be in the paging of whole coverage.If do not receive the page response of desired mobile station yet, just all locating areas send the paging request in the coverage.This cellular communication system is applicable to gsm system etc. by macro cells (macrocell) construction system, and the PHS system belongs to microcellulor sub-district (microcell), and the coverage of each base station is very little, not the notion of locating area.
Therefore, need to propose the paging method of a kind of PHS of being applicable to system really,, reduce the possibility of network congestion with effective saving paging channel.
Summary of the invention
The object of the present invention is to provide a kind of accurate paging method and device, reduce the paging bandwidth that beep-page message takies, improve the utilance of paging channel, thereby reduce the possibility that the hot zones paging channel is blocked, finally improve called call completing rate.
The present invention is by improving the paging occasion and the mode of base station, employing the CSC of nearest service is carried out a paging and do not have the response back other CSC in the current paging zone is carried out the secondary paging mode to reduce aerial paging traffic, finally reach the purpose that improves called call completing rate.
The network element that the present invention is used for personal handyphone system (PHS) is divided into plurality of paging district (PA) physically, a gateway (GW) comprises several PA, a PA comprises several base station controllers (CSC), a base station controller comprises several base stations (CS), gateway (GW) is set up mobile phone-base station controller (PS-CSC) correspondence table, and this correspondence table comprises the phone number (PS-Number) of mobile phone and provides the base station controller identifier (CSC-ID) of the CSC of service accordingly recently with this phone number; Comprise the steps:
1) when a phone number is called, a paging of the called for this reason initiation earlier of GW;
2) GW obtains the CSC of service recently according to phone number inquiry correspondence table, CSC under current PA and CS send (SETUP) message that connects then; " SETUP " message contains paging and sends indication; and indication has only the CS under the CSC of nearest service to send paging aloft, and remaining CS does not send;
3) CSC to " SETUP " message do not make any modification, the CS under being routed to it separately;
4) CS is according to receiving " SETUP " paging send indication and determine whether sending paging aloft;
5) if PS has response at the appointed time, signaling is transmitted in point-to-point mode between PS and network; Mobile phone-base station controller (PS-CSC) correspondence table is constant;
6) if PS does not respond at the appointed time, paging is overtime, illustrates that this PS is not under the CSC of service recently and under other CSC, so, GW initiates the secondary paging, and the CS under the CSC of indication service does not recently send paging, and remaining CS in the current paging zone sends paging.
7) after the paging of GW secondary is finished, new cell-phone-base station controller (PS-CSC) correspondence table more.
The present invention reduces the paging bandwidth that beep-page message takies by accurate paging, improves the utilance of paging channel, thereby reduces the possibility that the hot zones paging channel is blocked, and finally reaches the purpose that improves called call completing rate.In network, use this function, can under existence conditions, improve volume of business.

Fig. 2 is the main flow chart of the accurate paging method of personal handyphone system of the present invention.
Fig. 3 is for after using method of the present invention, and the schematic diagram of stream is broadcasted in a called paging.
Fig. 4 is for after using method of the present invention, and the schematic diagram of stream is broadcasted in called secondary paging.
Embodiment
The present invention is directed to the PHS network, the method by accurate paging is to reach the purpose that improves called call completing rate.Its measured PHS air interface and interface Q.931, the opportunity and the mode that the base station are sent paging are optimized improvement, reduce the paging bandwidth that beep-page message takies by accurate paging, improve the utilance of paging channel, thereby reduce the possibility that the hot zones paging channel is blocked, finally reach the purpose that improves called call completing rate.
The present invention improves the paging occasion and the mode of base station, employing the CSC of nearest service is carried out a paging and do not have the response back other CSC in the current paging zone is carried out the secondary paging mode to reduce aerial paging traffic, finally reach the purpose that improves called call completing rate.
To achieve these goals, GW at first will set up the PS-CSC correspondence table, and main information comprises the phone number (PS-Number) of PS and the base station controller identifier (CSC-ID) of the CSC of service is provided recently.When PS has experienced Location Registration, incoming call, exhalation, or the business crossed of any other and network interaction, GW can obtain the phone number of this PS and the CSC-ID of service is provided.GW inquires about this table according to phone number, if a new record PS-Number/CSC-ID is then inserted in the not login in table of this phone number; If this phone number existing record but provide the CSC of service to change in table, the CSC-ID of new record more then; Other situation then remains unchanged.
See also Fig. 2 to Fig. 4, specific implementation method of the present invention comprises the steps:
1) when submitting when called, GW is called for this reason to initiate a paging earlier.
2) GW obtains the CSC of service recently according to phone number inquiry correspondence table, CSC under current PA and CS send (SETUP) message that connects then; " SETUP " message contains paging and sends indication; and indication has only the CS under the CSC of nearest service to send paging aloft, and remaining CS does not send.Because PS can return page response by the arbitrary CS under current PA after receiving paging, thus the CS that does not send paging before page response also receivable to and keep that GW sends " SETUP " message.
3) CSC to " SETUP " message do not make any modification, the CS under being routed to it separately.
4) CS is according to receiving " SETUP " paging send indication and determine whether sending paging aloft.No matter whether send paging, CS receives " SETUP " after should start the page response that the T301 timer is waited for PS.
5) if PS responds at the appointed time, then signaling is transmitted in point-to-point mode between PS and network, and the PS-CSC correspondence table is constant.
6) if PS does not respond at the appointed time, paging is overtime, illustrates that this PS is not under the CSC of service recently and under other CSC.So, GW initiates the secondary paging, and different with a paging is to indicate the affiliated CS of CSC of service recently not send paging, remaining CS transmission paging in the current paging zone.
7) for the secondary paging, the way of CSC and CS is identical with a paging, and after the secondary paging was finished, GW was according to the PS CSC at place, more new cell-phone-base station controller (PS-CSC) correspondence table at that time.
The present invention only need revise network side related protocol Q.931, and PS without any specific (special) requirements, is not existed compatible and transitional problem.Existing systems need be done corresponding modification to following components:
1.GW change:
1) GW sets up and safeguards the PS-CSC correspondence table, and main information is the phone number of PS and the CSC-ID that the CSC of service is provided recently.When PS has experienced Location Registration, incoming call, exhalation, or the business crossed of any other and network interaction, GW can obtain the PS-Number of this PS and the CSC-ID of service is provided.GW inquires about this table according to PS-Number, if a new record PS-Number/CSC-ID is then inserted in this PS-Number not login in table; If this PS-Number existing record but provide the CSC of service to change in table, the CSC-ID of new record more then; Other situation then remains unchanged.
When 2) one of every startup is called, GW sends a paging earlier, obtain the CSC of service recently according to PS-Number inquiry correspondence table, CSC under current PA and CS send then " SETUP " message; " SETUP " message contains paging and sends indication; and indication has only the CS under the CSC of nearest service just really to send paging aloft, and remaining CS does not all send.
3) if PS does not respond at the appointed time, paging is overtime, illustrates that this PS is not under the CSC of service recently and under other CSC.So, GW initiates the secondary paging, and different with a paging is to indicate the affiliated CS of CSC of service recently not send paging, remaining CS transmission paging in the current paging zone.After the secondary paging, GW is according to the PS CSC at place, more new cell-phone-base station controller (PS-CSC) correspondence table at that time.
2.CSC change: CSC only needs compatiblely comprise paging and send the called of indication " SETUP " message.
3.CS change:
1) CS is according to receiving " SETUP " paging send indication and determine whether sending paging aloft.
2) no matter whether send paging, CS receives " SETUP " after should start the page response that the T301 timer is waited for PS.
Existing paging scheme is that all CSC and the CS under the current PA sends paging aloft, and it is bigger not consider that PS still is in the interior possibility of nearest service range, thereby has sent a lot of ineffertive pagers.The present invention depends on the hit rate of a paging to the reduced rate of aerial paging traffic, and just PS still is in probability under the nearest service CSC when a paging.
Suppose that a GW connects N CSC, each CSC connects K CS, and a paging hit rate is P, and under M called situation, the Various types of data of aerial paging can be calculated by following formula so:
A paging number is by the CSC transmission of nearest service: M *K
A paging is successfully counted: M *P
Paging failure number a: M *(1-P)
Secondary paging number is sent by other CSC: M *(1-P) *(N-1) *K
Total paging number is twice paging sum: M *K+ (M *(1-P) *(N-1)) *K
Original total paging number: M *N *K
With original comparing, total paging number of minimizing: M *N *K-(M+ (M *(1-P) *(N-1))) *K
Suppose that probability P is average probability 1/N, so
The total paging number that reduces: M *N *K-(M+ (M *(1-1/N) *(N-1))) *K=(M-1) *In fact K considers user behavior, and the moving range of most of user's most of the time is limited, and PS still is in nearest service CSC probability P down much larger than average probability 1/N during a paging, so total paging number of minimizing should be much larger than (M-1) *K.
