The working method of one call of bar channel bearing, referred to as full rate (Full Rate, FR), and 2 calls of a channel bearing
Mode is referred to as half rate (Half Rate, HR).The bearer cap of half-rate channel relative to full speed channel can with double, from
And the investment of radio carrier frequency is saved, without extra carrier frequency dilatation, the increase of Abis interface and frequency planning, can efficiently solve
Network congestion caused by bursts of traffic amount.But half rate also brings along some negative effects, such as：During call speech quality decline,
Number of dropped calls increase etc., therefore, half rate be mainly used to alleviate bursts of traffic caused by radio congestion, should not using half rate as
The Main Means of wireless network dilatation, therefore, when carrying out channel distribution, it will typically follow busy increase HR use ratio
Example, FR use is reduced, idle reduces HR use, ensures the principle for the requirement that FR is preferentially used.However, the nothing of prior art
In the method for salary distribution of line channel, pressure communication is alleviated in the case where channel resource is in short supply usually using half rate in operator,
And it is often that HR startup threshold sets are very low in order to lift busy half rate HR ratios, it could so not gathered around in busy guarantee
Plug, but too low HR starts thresholding and causes idle to also have to start half rate, can not meet that idle will reduce HR use, need
FR is wanted preferentially to use.Therefore, wireless channel can not be adjusted flexibly according to the actual requirements for the method for salary distribution of prior art wireless channel

Embodiment
In order that technical problems, technical solutions and advantages to be solved are clearer, clear, tie below
Drawings and examples are closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only
To explain the present invention, it is not intended to limit the present invention.
The embodiment of the present invention one provides a kind of wireless signal channel collocation method, is set up in existing communication system hardware structure
One server, main two aspects of completing work：Traffic statistics in real-time synchronization NM server are (such as every 15 points
It is subsynchronous that clock carries out one).To taken traffic measurement, the adaptive configuration algorithm built in carries out data analysis, generation real-time half
Rate channel and packet Dedicated Traffic Channel (Packet Data Traffic Channel, PDTCH) allocation plan, and synchronously
Generate perform script and import NM server execution, complete adaptive configuration.Referring to Fig. 1, method flow includes：
S101, the traffic statistics for obtaining cell in a upper period in real time；
S102, the service condition according to cell channel resource in the traffic statistics analysis upper period；
S103, according to the service condition and default algorithm of the channel resource channel resource dynamically distributes are grouped
Traffic data channel PDTCH and half-rate channel quantity.
In an optional scheme, traffic statistics included the telephone traffic of cell, Dan Shi in the upper period
Gap multi-user voice business (Voice Services over adaptive Multi-user channels on one
Slot, Vamos) match busy telephone traffic, BCCH channel of broadcast control quantity, Separate Dedicated Control Channel SDCCH quantity, cell
Present channel quantity and packet data traffic channel PDTCH reusing degrees；
Step S102, the use feelings of cell channel resource in the upper period were analyzed according to the traffic statistics
Condition, including：
Calculate the telephone traffic and subtract the result of the Vamos pairings busy telephone traffic, and inquired about and liked according to result of calculation
Er Lanbiao obtains the traffic channel quantity being currently needed for；
Calculate currently available channel quantity, the available channel quantity=cell present channel quantity-BCCH
Quantity-SDCCH quantity；
Calculate half-rate channel breach x, traffic channel quantity-available channel quantity that x=needs；
The gear number of PDTCH reusing degrees is determined according to the PDTCH reusing degrees.
, can be with the gear number of empirically determined PDTCH reusing degrees in practical application：
It is defined as low grade when PDTCH reusing degrees are less than 1.5, is defined as when PDTCH reusing degrees are between 1.5 and 4
Middle-grade, it is defined as top grade when PDTCH reusing degrees are more than 4.
In an optional scheme, step S103, according to the default algorithm of the service condition of the channel resource to institute
The quantity of channel resource dynamically distributes Packet Data Traffic Channel and half-rate channel is stated, including：
According to the value of the half-rate channel breach x, the gear number of the PDTCH reusing degrees and the default algorithm distribution
The PDTCH and the half-rate channel quantity.
In practical application, balance can be found between channel congestion situation and CS and PS channel occupancy improving, and take into account
CS is preferential, and preferentially, preset formula can be according to following strategy setting for Traffic Channel (Traffic Channel, TCH)：
1. traffic channel preferentially takes, voice service is preferential.
2. due to a full speed channel can only user use, and a half-rate channel can make for two users
With compared with full speed channel, the bearer cap of half-rate channel can be with double.Therefore, when telephone traffic is busy just as far as possible
Full speed channel is converted to half-rate channel and uses (occupation proportion for improving half-rate channel), to alleviate congestion.
3. in the case where channel is enough, half rate is not used as far as possible, to improve voice quality.
4. in the case where full speed channel is enough, idle channel distributes dynamic PDTCH as far as possible, is beneficial to PS business speed
The offer of rate.
5. in the case of have different magnitude PDTCH assignment requests, accomplish half-rate channel and PDTCH channel distributions it
Between balance.
6. considering the behavior of system user, if PS requests are not met, can constantly retry, therefore, in any case
It should allow some leeway to PS business, at least retain one.
Based on mentioned above principle, the preset algorithm that is used in the present embodiment is following, it is necessary to explanation, under different scenes,
Corresponding preset algorithm also differs.
For convenience of description, half-rate channel breach x calculation formula is referred to as turning into formula one by the present invention：
Traffic channel quantity-available channel quantity that x=needs
It can be seen from formula one as x ＜ 0, illustrate that quantity is for available channel (Traffic Channel, TCH)
More than the TCH quantity of needs, half-rate channel is not at this moment needed；As x=0, show current TCH full speed channels quantity just
Meet the TCH of needs, without congestion；As x ＞ 0, show that current system traffic is busy.
Therefore, it is divided into three scenes according to x span to illustrate default formula：
Scene one：X ＜ 0
Now available TCH quantity has been above the TCH quantity needed, does not at this moment need half-rate channel.
Reference policy 4, when carrying out dynamically distributes, remaining full speed channel after CS demands will be met, maximized complete
Portion is converted to dynamic PDTCH, i.e.,：
Need the PDTCH quantity distributed：PDTCH_Dynamic=abs (x)；
Need the half-rate channel quantity distributed：HR_convert=0.
Scene two：X=0
Current TCH full speed channel quantity is just met for the TCH needed, without congestion (may not be most busy, nor
Most idle).Only consider from CS operation angles, at this moment do not need half-rate channel.But in order that half-rate channel and PDTCH distribution
It is reasonable, so as to balance PS channels, PDTCH distribution needs to consider following 4 kinds of situations：
When PDCTH reusing degrees are 0, i.e., there are not PDTCH assignment requests in a upper period, according to tactful 6, then needs point
With at least one PDTCH, and it is half rate to convert a TCH, i.e.,：
PDTCH_Dynamic=1；HR_convert=1.
When PDCTH reusing degrees are not 0, it is allocated according to the gear number of PDCTH reusing degrees：
If PDCTH reusing degrees are low grade, a PDTCH is distributed, changes a TCH as half-rate channel.I.e.：
PDTCH_Dynamic=1；
HR_convert=1.
If PDCTH reusing degrees are middle-grade, PDTCH quantity=PDTCH reusing degree middle-grade proportionality coefficient * TCH_ for distributing
Aval=Mid_pd*TCH_aval, while the available TCH quantity of corresponding conversion Mid_pd ratios is half-rate channel, i.e.,：
PDTCH_Dynamic=Mid_pd*TCH_aval；
HR_convert=Mid_pd*TCH_aval.
If PDCTH reusing degrees are top grade, the PDTCH quantity distributed=advanced proportionality coefficient * TCH_aval=High_
Pd*aval, while the available TCH of corresponding conversion High_pd ratios is for half rate：
PDTCH_Dynamic=High_pd*TCH_aval；
HR_convert=High_pd*TCH_aval..
Specifically, define PD reusing degree middle-grade proportionality coefficients Mid_Pd, high-grade proportionality coefficient High_Pd, recommendation Mid_
Pd=1/4；High_Pd=1/2；System can configure a scope when realizing, default value uses Mid_Pd=1/4；High_Pd
=1/2.
Scene three：X ＞ 0
Current system traffic is busy, and on the occasion of bigger, represents that system is busier.At this moment primarily solve asking for congestion
Topic, half-rate channel is changed as far as possible to meet traffic requirement.It can be now allocated according to jam situation.Congestion is calculated first
Rate HR_convert_threshold=x/TCH_aval；
If HR_convert_threshold ＞=100%, showing system extreme congestion, channel resource is inadequate, now,
Available channel is wholly converted into half-rate channel as far as possible, and PDTCH is not distributed as far as possible.But with reference to strategy 6, also at least to keep one
Pd, that is, a PDTCH is only distributed when distributing, remaining available channel is completely converted into half-rate channel, i.e.,：
PDTCH_Dynamic=1；
The available channel TCH_aval-1 of HR_convert=.
If HR_convert_threshold ＜ 100%, at this moment a TCH part is converted into half rate, now
The available channel quantity TCH_aval of traffic channel quantity TCH_request- that half-rate channel breach x=needs；
The calculation formula that residue need not turn the TCH quantity rest_TCH of half-rate channel is as follows：
Rest_TCH=TCH_aval-x=TCH_aval*2-TCH_reauest
Consider PDTCH demand, but because PDTCH is full speed channel, undertake the demand of traffic all the way.Therefore often with one
Bar needs more conversion half-rate channels to support the traffic demand needed for original full speed channel, therefore again in PDTCH
Need to be allocated according to PDCTH reusing degrees：
If DTCH reusing degrees are that 0, PDTCH originally need not divide in a upper period, CS business was all left for.But refer to plan
Slightly 6. will at least divide a pdtch, that is, distribute a PDCH, while change x+1 bar half-rate channels, i.e.,：
PDTCH_Dynamic=1；
HR_convert=1+x.
If DTCH reusing degrees are not 0 in a upper period, it was allocated according to the gear number of PDCTH reusing degrees.
If PDTCH reusing degrees are low grade, retain a PDTCH dynamic channel, one TCH of increase is half rate, i.e.,：
PDTCH_Dynamic=1；
HR_convert=1+x.
If PDTCH reusing degrees are middle-grade, retain PDTCH dynamic channels=intermediate proportionality coefficient * rest_TCH=
Mid_pd* (TCH_aval*2-TCH_request), the TCH of reciprocity quantity is changed as half rate, i.e.,：
PDTCH_Dynamic=Min { Mid_pd* (TCH_aval*2-TCH_ava1), rest_TCH/2 }；
HR_convert=x+PDTCH_Dynamic；
If PDTCH reusing degrees are top grade, retain PDTCH dynamic channels=advanced proportionality coefficient * rest_TCH* busy
PDTCH discount factors=High_pd*rest_TCH*y, the TCH of High_pd*rest_TCH*y quantity are changed as half rate, i.e.,：
PDTCH_Dynamic=Min { High_pd*rest_TCH*y, rest_TCH/2 }；
HR_convert=x+PDTCH_Dynamic.
It should be noted that in above-mentioned calculation formula, y refers to busy PD discount factors y.When traffic is busy, PDTCH is assigned
Requirement to channel can not meet simply, give a discount, the recommendation folding of default value 8,80%；To vacate TCH conversion half rates
Used for CS traffics.
The present embodiment is illustrated with reference to concrete scene, presets every 15 minutes and carries out a config update：
First, need to set 3 cell-level parameters in the server：
Intermediate proportionality coefficient Mid_pd；This be obtain the PDTCH reusing degrees of previous 15 minutes granularities between 1.5 and 4 it
Between, rule of thumb it is considered medium rank, recommends default value 25%；Corresponding regulation proportionality coefficient；
Advanced proportionality coefficient High_pd；This is that the PDTCH reusing degrees for obtaining previous 15 minutes granularities reach more than 4, root
It is considered high-grade according to experience, it is 50% to recommend default value；Corresponding regulation proportionality coefficient；
Busy PDTCH discount factors y：(when traffic is busy, PDTCH assigns the requirement to channel to meet simply, to beat
Individual discount, it is 80% to recommend the folding of default value 8, is used to vacate TCH conversion half rates for CS traffics.)
Secondly, wireless channel configuration server needs the traffic statistics read, including：
Preceding 15 minutes cellular traffics；
Preceding 15 minutes cells PDTCH reusing degrees；
Preceding 15 minutes cell Vamos match quantity --- increased Irish number；
Preceding 15 minutes cell BCCH quantity and SDCCH quantity.
Using the currently available channel quantity of cell as 50, it is assumed that preceding 15 minutes minimum particle sizes are according to traffic statistic data meter
The traffic channel quantity that calculating needs is 80；The channel allocation algorithm of so next granularity is as follows：
X=80-50=30 bars, the algorithm of scene three is applicable, calculates congestion rate HR_convert_threshold=x/
TCH_aval=30/50 ＜ 100% according to the gear number of PDTCH reusing degrees, it is necessary to be allocated：
Remaining channel quantity rest_TCH=50*2-80=20 bars；
If at most 1/2 needs of the preceding 15 minutes PDTCH reusing degrees in top grade, remaining rest_TCH are converted into
PDTCH, now：
PDTCH_Dynamic=Min (High_pd*rest_TCH*y, rest_TCH/2)=Min (50%*20*80%,
20/2)=Min (8,10)=8
The PDTCH for needing to change is calculated no more than 10, busy PDTCH discount factors y is 80%, has beaten 8
Roll over for 8, i.e.,：
PD_Dynamic=8, now HR_convert=x+PD_Dynamic=30+8=38 bars.
End product is 80 CS business demands, has 38 TCH conversion half rates, forms 76 HR.Expired again with 4 TCH
The whole 80 CS business demands of foot.Then TCH_aval sums are 50, are left 50-38-4=8 bars, are used for PDTCH.
Can be more than 10 (parameter settings for depending on server) if High_pd*y is calculated, then PDTCH_
Dynamic at this moment also can only capping 10, i.e. PDTCH uses up 10, because also needing to have 10 TCH to be converted into again below
HR just balance corresponding to CS traffic demands.Finally calculate to obtain PDTCH_Dynamic=10, HR_convert=x+PDTCH_
Dynamic=30+10=40 bars.
In the case where traffic is very busy, PS portfolios are also very big, in order to protrude PS business demands, can by discount because
Son is arranged to 1, does not give a discount, TCH full speed channel resigning PS business demands.
At this moment system aspects realize equilibrium allocation, i.e., at next nearest 15 minutes, on the one hand can meet 80
User's communication demand, the remaining TCH channels of another aspect can also determine it is to be completely used for supporting PDTCH according to demand, still enter
The certain discount of row supports PDTCH again.
In practical application, opened in dynamic SDCCH functions, after a large amount of location updatings of appearance are a large amount of, dynamic translation is preferential,
Dispensed in TCH_aval.After location updating burst terminates, TCH category will be reverted to by participating in the channel of dynamic SDCCH conversions
Property, become TCH_aval again.
After the unlatching of Vamos functions, a regional telephone traffic should not substantially increase and add deduct because of Vamos opening
It is few, except non-congested serious cell or period.So under the occasion matched with Vamos, it may not be necessary to change above-mentioned algorithm,
FR after algorithm process and in HR mixing ratio, pairing is conciliate in the Vamos pairings for carrying out FR and HR.Can further it reduce
Congestion Level SPCC when busy.
It should be noted that when adding dynamic SDCCH and/or adding Vamos, dynamic SDCCH is in order to tackle burst signaling
The change of demand, mostly transient state；And Vamos adds the capacity of voice channel.
Dynamic SDCCH conversions influence the calculating to TCH_aval after starting, have no effect on algorithm in itself, and SDCCH dynamics turn
Change peculation and recovery that function completes TCH in itself.
Vamos functions are open-minded, beneficial to improving power system capacity, and algorithm uses as usual.After Vamos activation, it can alleviate busy
When congestion condition.Vamos is used at one's leisure, can cause the telephone traffic according to statistics, looks into the channel demands that Irish table obtains
It is on the high side.
And in practical application, if not using so multichannel, the feedback data matched according to Vamos is at this moment needed,
One compensation is done to PDTCH applications.The telephone traffic that current Vamos has more, the corresponding TCH quantity saved, can be fed to dynamic
PDTCH, on algorithm when calculating TCH_aval, the situation of busy traffic is matched according to previous granularity Vamos, is deducted.
The wireless signal channel collocation method of the present embodiment, traffic statistics that can be in real-time synchronization NM server.It is right
Taken traffic measurement adaptive configuration algorithm built in carries out data analysis, generates real-time half rate and PDTCH configuration sides
Case.And synchronously generate command script and import NM server and perform, when completing adaptive configuration, and can ensure system busy or
Idle, accomplish reasonable distribution between CS business and PS.
