Fig. 1 shows a kind of method of elimination paging subchannel congestion of the embodiment of the present invention
Flow chart.
With reference to Fig. 1, the method for the elimination paging subchannel congestion that the embodiment of the present invention is proposed,
Specifically include following steps：
S11, the beep-page message quantity received according to IU interfaces, determining needs in paging subchannel
The beep-page message quantity dispatched by transmission；
S12, the paging capacity for obtaining the paging subchannel；
S13, when need in the paging subchannel dispatch send beep-page message quantity be more than
Or equal to the paging subchannel paging capacity threshold value when, checking needs in the paging subchannel
The paging reason of the beep-page message that scheduling sends；
Wherein, the paging capacity threshold value is less than the paging capacity；
S14, according to the paging reason of each beep-page message, it is suitable according to default paging priority
Sequence sends the beep-page message for needing scheduling to send.
Wherein, paging reason can be got from the beep-page message PAGING of IU interfaces, mesh
Paging reason is carried all in the beep-page message that front core net sends.
In this step, when beep-page message quantity to be sent is more than or equal to the paging subchannel
Paging capacity threshold value when, by preferential according to default type of service to beep-page message quantity
Level sequence, it is preferential to ensure that CS service pagings and the paging first of other PS business send.
The embodiment of the present invention, it is by being analyzed to the beep-page message more than paging capacity, excellent
First ensure the paging first of CS service pagings and other business, abandon the repetition of other business
Paging, is reduced to a certain extent due to the big caused RNC of device interior beep-page message amount
Machine utilization is raised, the probability that stability is reduced, and significantly reduces device interior message count
Amount, improves stabilization of equipment performance.
Specifically, in the present embodiment, the acquisition modes of the paging capacity threshold value, including：
According to equipment current loads state, capacity regulation coefficient is determined；
Using the product of the paging capacity and capacity regulation coefficient of the paging subchannel as described
The paging capacity threshold value of paging subchannel.
In this step, paging capacity * percent coefficient of the paging capacity threshold value by paging subchannel
Obtain, the percent coefficient is capacity regulation coefficient, and capacity regulation coefficient can be according to RNC
Load does dynamic adjustment.The paging quantity in certain paging subchannel that such as falls reaches the sub- letter
Road capacity paging capacity 90% when, start-up check paging reason by paging priority send work(
Can, all send less than when this, wherein:
Paging capacity threshold value=paging capacity x 90%.
It will be appreciated that paging capacity of the maximum of paging capacity for paging subchannel.
In an alternative embodiment of the invention, as shown in Fig. 2 the elimination paging subchannel is gathered around
The method of plug, it is further comprising the steps of：
S15, when need in the paging subchannel dispatch send beep-page message quantity be more than
During the paging capacity of the paging subchannel, the international mobile subscriber carried in counting beep-page message
Identification code IMSI, obtains statistical report form；
S16, the statistical report form is reported into equipment of the core network so that equipment of the core network according to
The paging interval of the corresponding beep-page messages of IMSI in the statistical report form adjustment statistical report form.
The embodiment of the present invention, by the paging capacity for calculating wall scroll paging subchannel, if single
Certain beep-page message time of reception corresponding paging in the position time (week PBP in paging week)
When beep-page message quantity to be sent on channel exceedes paging subchannel capacities, statistics paging disappears
IMSI value statistical report form is reported to submit to Virtual network operator in breath, Virtual network operator can evidence
This adjustment IMSI paging interval.Avoid due to paging caused by IMSI irrational distributions
Channel congestion, and be to receive carried out after beep-page message at once paging subchannel appearance from IU interfaces
Amount judgement, so that Virtual network operator is adjusted to IMSI paging intervals in time,
Reduced as device interior beep-page message amount is big and concentrates caused RNC to set to a certain extent
Standby load is raised, the probability that stability is reduced, and is set for paging channel congestion, reduction is reduced
Standby load, the purpose of raising stabilization of equipment performance have positive role.
Further, in step S14 according to default paging priority orders send institute
Before stating the beep-page message for needing scheduling to send, methods described is further comprising the steps of：
According to the requirement of real-time of the corresponding type of service of each beep-page message, to beep-page message
Paging prioritization is carried out, it is each in the beep-page message for needing scheduling to send to determine
The paging priority orders of beep-page message；
Specifically, the priority of the paging priority is followed successively by：
Voice paging>The paging first of the business in addition to speech business>In addition to speech business
Business repeated paging.
It should be noted that the embodiment of the present invention is wanted to real-time according to different kinds of business
Ask different, paging is carried out prioritization by reason by business, as shown in figure 3, preferentially
Level highest is important paging, such as voice paging, preferentially ensures that its paging is dispatched, is secondly
The paging first of other business in addition to speech business, priority it is low for inessential paging,
The repeated paging of the business such as in addition to speech business, occurs when certain paging subchannel is adjudicated
Loss priority relatively low beep-page message is paid the utmost attention to during congestion.
Further, the step of methods described also includes with not shown in figure below：
The beep-page message of the paging capacity more than current paging subchannel is abandoned, record is dropped
The corresponding IMSI information of beep-page message.
Specifically, the beep-page message quantity for sending in paging subchannel is close to paging subchannel
During capacity threshold, preferential guarantee speech business is sent to the paging scheduling in the paging subchannel
(Conversational) paging (include a paging of speech business, secondary paging, three times
The pagings such as paging) and the paging first of other business scheduling send, ensure in both first
The paging of speech business, next to that the paging first of the business in addition to speech business.Protecting
It is on the premise of card voice service page, the paging first of other business can obtain scheduling transmission, right
In other service pagings, send if it can obtain dispatching send opportunity, for more than paging
Subchannel capacities are then abandoned, and record is dropped the IMSI information of paging.
In the embodiment of the present invention, if it exceeds paging subchannel capacities do discard processing, it is to avoid
Beep-page message is distributed on all cell place DSP by LAC/RAC and judges that paging is believed again
Whether road has congestion, using device interior message number is this approach reduced, improves equipment steady
It is qualitative.
Further, the beep-page message quantity received according to IU interfaces, determines paging
Need to dispatch the beep-page message quantity for sending on channel, specifically include with not shown in figure below
Step：
When the beep-page message of equipment of the core network transmission is received, according to taking in the beep-page message
The IMSI of band calculates the paging time of reception of the beep-page message and corresponding paging subchannel；
The beep-page message quantity that paging subchannel described in counting the paging time of reception is received.
It will be appreciated that the working mechanism of RNC is such, IU interfaces are received
The beep-page message that MSC/SGSN sends, will count according to IMSI to each beep-page message
Calculation should be sent in which bar paging subchannel, when next paging cycle is reached, sought
Delivery time is exhaled to have beep-page message send by PICH channel notifications UE, then in paging
The time of reception sends out paging, and terminal receives paging in the paging time of reception, so as to realize
The discontinuous paging receiving message of terminal.
In actual applications, what the IU interfaces of RNC received that MSC or SGSN sends seeks
Message is exhaled, calling time (Paging Occasion) and the beep-page message time of reception is calculated
(Paging Message Receiving Occasion), believes in PICH in calling time RNC
Road sends paged end message, and terminal reads the data that PICH sends in calling time,
Indicate to judge to abandon if oneself corresponding position is as 0 according to bitmap after receiving, wait until down
One calling time reads PICH channels again, if 1, then illustrates have on PCH channels
One's own beep-page message, terminal calculate the beep-page message time of reception, and in beep-page message
The time of reception reads paging data from PCH channels.UTRAN and terminal employ identical
Formula and parameter calculate calling time and the beep-page message time of reception, therefore ensure that net
Network side sends message and receives the consistent of message moment, calling time and beep-page message with terminal
The time of reception is calculated by equation below：
Paging Occasion={ (IMSI div K) mod (DRX cycle length div PBP) }
*PBP+n*DRX cycle length+Frame Offset
Paging Message Receiving Occasion=Paging Occasion+NPICH
+NGAP+{(DRX Index mod Np)mod NPCH}*2
Parameter declaration is as follows：
IMSI：International mobile subscriber identity, is the mark for distinguishing mobile subscriber, stores handss
Machine is in SIM.
K：The SCCPCH channel numbers of configuration, require each factory of current existing network according to operator
Commercial city is configured to 1
DRX cycle length：Discontinuous reception length of the cycle, existing network representative value are configured to
64 (unit is frame, and one frame of TD-SCDMA system is 10ms)
n:For discontinuous reception length of the cycle number of times, value 0,1,2,3 ..., paging is in DRX
Interior transmission.(illustrate, if DRX is 128 (0～127), when sending paging for the first time
Carve as 100, then second delivery time is 100+DRX length 128, third time paging is sent out
Send be constantly 100+2*DRX length 128 ...., by that analogy)；
PBP(Paging Block Periodicity)：Paging block periodicity, with DRX cycle length
64 frames are equally.
NPICH：The successive frame number of mark PICH channel occupancies.
NPCH:The paging subchannel number that mark PCH is included, each manufacturer's configuration of existing network is by most
Big value 8 is configured.
NGAP：Represent the frame number between the ending and the beginning of PCH blocks of PICH blocks.
Np：The paging included in each PICH Block indicates number, a wireless son
Frame carries data 352bit, and a paging indicating length is 8, therefore Np=352/8=44.
Frame Offset：Vertical shift is represented, for equally loaded.For common signal channel, Frame
Offset is always defined as zero.
RNC indicates block (PICH Block), paging with paging respectively in PICH, PCH channel
Block (PCH Block) sends paging indicating message and beep-page message for unit, and a paging refers to
Show that block takes 2*N in time domainPICHIndividual radio frames, a paging block take 2*N in time domainPCH
Individual radio frames, NPCHIt is the number of the paging subchannel included in paging block, therefore one is sought
Subchannel is exhaled to take 2 radio frames in time domain.
Paging Sub-Channel Number is calculated by (DRX Index mod Np) mod NPCH,
TS25.304 agreements specify that the computing formula of DRX Index is as follows：
DRX Index=IMSI div 8192
Illustrate：Assume that an IMSI is 460027670433352, then by (DRX Index
mod Np)mod NPCHFormula is calculated：
(((460027670433352/8192) mod 44) mod 8)=4, then this IMSI is corresponding
The beep-page message of UE send in the paging subchannel 4 of PCH channels.
The embodiment of the present invention, after the high-level signaling of RNC receives IU interface paging message, i.e.,
The paging subchannel for calculating the beep-page message time of reception and transmission is carved, and counts the paging
The beep-page message quantity that paging subchannel described in the time of reception is received, judges correspondence paging son letter
Whether road can occur paging congestion, rather than be made a decision until dispatching transmission again, have
Effect reduces RNC inside stories interaction, improves system stability.
In embodiments of the present invention, the method for the elimination paging subchannel congestion, also include with
The step of not shown in figure below：
When the beep-page message of equipment of the core network transmission is received, judge that current beep-page message is
It is no to belong to paging first.
