Fig. 1 is the flow chart of paging parameters self-organization method one embodiment in LTE network of the present invention.As shown in figure 1,
Paging parameters self-organization method in the embodiment LTE network includes：
110, evolved base station（Evolved NodeB, eNodeB, referred to as：eNB）Monitor and count paging load and paging
Performance.
120, eNB are triggered according to predetermined period or based on predeterminable event, the paging load and paging performance that statistics is obtained
Statistical result report oam（OperationAdministration and Maintenance, OAM）System
System.
130, OAM systems according to the statistical result of paging load and paging performance determine the need for change paging parameters with
And need the paging parameters adjusted.
140, in response to needing to change paging parameters, OAM systems calculate the paging for needing to adjust using default optimized algorithm
The adjusted value of parameter, and paging parameters adjustment notification message is sent to eNB, paging parameters adjustment notification message includes needs
The paging parameters and its adjusted value of adjustment.
150, eNB adjust notification message according to the paging parameters received is adjusted to the paging parameters for needing to adjust,
And the paging parameters after adjustment are notified into UE, so that UE receives beep-page message according to the paging parameters after the adjustment.
Paging parameters self-organization method in the LTE network that the above embodiment of the present invention provides, eNB are monitored and are counted paging
After load and paging performance, statistical result is reported into OAM systems, OAM systems are according to the statistics of paging load and paging performance
As a result the paging parameters changed paging parameters and need to adjust are determined the need for, and when needing to change paging parameters, are adopted
The adjusted value for the paging parameters for needing to adjust is calculated with default optimized algorithm, and paging parameters adjustment notification message is sent to eNB,
It is adjusted by eNB according to the paging parameters adjusted accordingly to needs, and the paging parameters after adjustment is notified into user terminal UE,
So that UE receives beep-page message according to the paging parameters after the adjustment.Thus, the embodiment of the present invention is realized in LTE network
The self-optimizing of paging parameters, effectively increases the paging performance of LTE network, and reduces artificial network optimization cost, solves existing
The technical problem that technology artificial optimization's paging parameters are wasted time and energy.
In LTE, special physical layer Page Indication Channel is not configured for UE, beep-page message is shared by physical down
Channel（PDSCH）Carrying, and need to receive Physical Downlink Control Channel of the paging mark in routine of beep-page message（PDCCH）
Upper carrying.Comparatively, the PDCCH signaling duration is very short in LTE, therefore intermittently monitors PDCCH to UE power consumptions
Influence smaller.
UE periodically listens for PDCCH, if having demodulated pager wireless net network temporary mark from PDCCH channels（P-
RNTI）, i.e.,：Paging mark, then it represents that PDSCH corresponding to UE needs receptions, then pass through paging transmission channel（PCH）Parameter
The data block for going parsing to be received from PDSCH, and then obtain beep-page message.And if terminal does not parse P- on PDCCH
RNTI, then without going to receive PDSCH physical channels again.In LTE agreement, the logic channel of bearing call message（PCCH）、
Transmission channel（PCH）And physical channel（PDSCH）Mapping relations it is as shown in Figure 2.
Three class parameters can be carried in the beep-page message of LTE network：System message alteration sign, seismic sea wave alarm
System（Earthquake and Tsunami Warning System, ETWS）Early warning sign and the user being paged are whole
End mark（UE_ID）List.This three classes parameter has indicated respectively three kinds of different purposes of beep-page message.
The most important function of beep-page message is that Non-Access Stratum signaling connection establishes notice.In the beep-page message that terminal receives such as
Fruit carries UE_ID lists, and UE needs to be matched one by one with the UE_ID carried in beep-page message with the UE_ID of oneself, to sentence
Whether this disconnected beep-page message is to call oneself.According to the definition in LTE standard to beep-page message, in a beep-page message,
The at most carry-on UE_ID of network depends on the PDSCH number of resources for paging, in general, in a beep-page message,
The at most carry-on UE_ID of network is no more than 16.
Other LTE has done many extensions to the purposes of beep-page message, except being connect for the normal terminal of ICQ terminal
Receive（MT）Outside business, it can also notify UE system messages that there occurs change and some warning information, such as earthquake or tsunami
Early warning etc..
For in wireless heterogeneous networks（Radio Resource Control, RRC）It is idle（RRC_IDLE）State or
Wireless heterogeneous networks connect（RRC_CONNECTED）UE under state, if changed in the beep-page message received with system message
Become sign, then it represents that system message will start to change in next modification cycle.In such cases, UE is disappeared by paging
Breath can not be accurately known that it is which system message is changed, so UE needs to re-read first in beep-page message
Class system relevent information block（System InformationBlock Type1,SIB1）, obtain the system information block in SIB1
（System InformationBlock, SIB）Ident value, then compare what this SIB ident value read was read with last time
Whether SIB ident values are identical, wherein, a SIB ident value is used to identify a system message.If this SIB read mark
Knowledge value is different with the SIB ident values that last time reads, then it represents that system message is changed, and UE is needed according to this reading
The schedule information of other systems message in SIB1 all again re-reads other all related system message one time, then makes
With business of the parameter in new system message before the cell is resident or is continued.
LTE network can notify UE to receive ETWS notification messages by beep-page message, allow user to obtain one in time
The information that a little emergencies occur.Earthquake or tsunami early warning are divided into two classes：The first kind is the early warning of emergency, is held by SIB10
Carry；Second class is to aid in the notice of rescue information, is carried by SIB11.
UE under RRC_IDLE patterns, discontinuous reception can be used（DRX）Mode go monitor beep-page message.
In one DRX cycle, UE can be only in corresponding paging frame（PF）On calling time（PO）Go to monitor and whether taken on PDCCH
With P-RNTI, and then go to judge whether there is bearing call message on corresponding PDSCH, the corresponding LTE radio frames of wherein PF,
PO corresponds to some subframe in mono- radio frames of LTE, and by PF and PO, UE is known that monitors beep-page message in which PF PO.
In LTE PHY, system wireless frame frame number（SFN）Repetition period be 256 frames, therefore each
SFN span is 0~255.Each SFN is divided into 10 subframes again, and the span of its subframe number is 0~9, each
1 millisecond of subframe.For one group of UE, PF and PO value have corresponded to the corresponding PDCCH for needing to detect in DRX cycle in running time-frequency resource
On the position of radio frames and the position of subframe in radio frames.Other times, UE can carry out DRX transmission, it is meant that Ke Yiguan
Receiver is closed to save the energy content of battery.
Wherein, PF value is determined by below equation：
SFN mod T=(T/N) * (UE_ID mod N)（1）
Wherein, T is DRX cycle, and mod represents remainder, and SFN mod T represent the remainder of SFN and T ratio, met above-mentioned
Formula（1）SFN value be PF.Other parameters are defined as follows in formula：
T：T takes UE acquiescence DRX parameters and the minimum value of specific DRX parameters.UE acquiescence DRX parameters are in LTE network
System message（SI）Middle broadcast, span 32,64,128,256, unit radio frames.UE specific DRX parameters are disappeared by RRC
Breath configuration, value 32,64,128,256, unit radio frames.
NB=4T, 2T, T, T/2, T/4, T/8, T/16, T/32, to page subframe parameter, the parameter is wide in the SI of network
Broadcast.
N=min (T, nB), it is the number of the paging frame in DRX cycle.
UE_ID:IMSI mod 1024, IMSI be UE unique International identification, international mobile subscriber identification code（IMSI）Take
Decimal number.
PO value is determined by below equation：
i_s=Floor（UE_ID/N）mod Ns （2）
Wherein, Floor represents downward round-off function, and mod represents remainder, and i_s is directed to accordingly page subframe, specific corresponding
Relation is as shown in table 1.Floor（UE_ID/N）Represent values of the UE_ID/N to round down.
Ns:Value is max (1, nB/T), indicates the number that subframe is paged in paging radio frames.For example, nB=T/2, Ns=1,
Illustrate only have a subframe to be used to page in each paging frame.
Table 1.i_s and PO corresponding relation（FDD）
| Ns | PO works as i_s=0 | PO works as i_s=1 | PO works as i_s=2 | PO works as i_s=3 |
| 1 | 9 | N/A | N/A | N/A |
| 2 | 4 | 9 | N/A | N/A |
| 4 | 0 | 4 | 5 | 9 |
It is exemplified below, if broadcast message is configured with T=32, nB=T, then according to formula（1）N=32 can be obtained, i.e., 32
In the DRX cycle of frame, it is likely to transmit beep-page message per frame；According to formula（1）With（2）Ns=1, i_s=0, according to table 1 can be obtained
Corresponding relation, can only have subframe 9 to transmit beep-page message per frame.Specific beep-page message and UE corresponding relations are SFN
32=UE_ID of mod mod 32, i.e. UE meet that the subframe 9 of formula S FN 32=UE_ID of mod mod 32 respective frame is supervised in SFN
Beep-page message is listened, the UE of all UE_ID mod N=0 monitors PCH, institute in the subframe 9 of the radio frames of SFN mod T=0
The UE for having UE_ID mod N=1 monitors PCH in the subframe 9 of the radio frames of SFN mod T=1, by that analogy.
