Embodiment one

The present embodiment provides a kind of TBF resource allocation method, is applicable under the preferential prerequisite of voice, and as shown in Figure 1, the method comprises:

Step 101, BSS (Base Station Subsystem, base station sub-system) from GPRS (General Packet Radio Service, gather type and the achievement data of residential quarter in the traffic measurement data of STS subsystem (the Statistics And Traffic Measurement Subsystem) statistics of the general packet radio service technology)/EDGE (Enhanced Data Rate for GSM Evolution, the abbreviation of enhanced data rates for gsm evolution technology);

The traffic measurement data are existing data in existing network, in the present embodiment, obtain the scanning times that the above-mentioned type and achievement data comprise the traffic carrying capacity of (be used for determine threshold value): EPDCH (the E Packet Data Channel that is used for EDGE), the traffic carrying capacity of BPDCH (the B Packet Data Channel that is used for GPRS), residential quarter TCH total traffic, residential quarter TCH configurable number, GPRS (General Packet Radio Service, GPRS) at least from the traffic measurement data.

Step 102, BSS is identified for the threshold value of TBF resource distribution according to described type and achievement data;

In the present embodiment and following embodiment, this threshold value represents with TBFxLLIMIT, and particularly this threshold value is divided into: up TBF threshold value and descending TBF threshold value.Wherein, TBFULLIMIT represents up TBF threshold value, and TBFDLLIMIT represents descending TBF threshold value.

In step 102, BSS is according to comprising that the type of foregoing and achievement data just can be identified for the threshold value of TBF resource distribution, further, for the threshold value that guarantees to determine gets reasonability, the type of this residential quarter and achievement data can also comprise (being used for proofreading and correct the lower value of the door of determining) at least: congestion ratio, TBF empties rate, half rate traffic ratio.Due to this trimming process and non-essential technological means, therefore concrete method of proofreading and correct please see step 203 in following embodiment two for details.

Step 103, BSS is according to the channel resource between described threshold value distribution voice and data service.

Specifically distribute the scheme of the channel resource between voice and data service to carry out according to existing mode according to this TBFxLLIMIT.For example: the TBFxLLIMIT that establishes after determining is 30, under the preferential prerequisite of voice, if when data service request allocated channel is arranged, judge the TBF of the current PDCH that takies shares to count whether reached 30, if no, this data service is distributed to this PDCH channel; If reached 30, judge current whether available free PDCH, if having this data service can be assigned on this idle PDCH.

TBF resource allocation method in the present embodiment can automatically be determined TBFxLLIMIT according to the type and the achievement data that gather the residential quarter of coming from traffic data, not only efficient is high, but also combine the parameters such as the type of residential quarter and achievement data in determining the process of TBFxLLIMIT, therefore can obtain the index of weighing every data and voice, determine this TBFxLLIMIT according to the different situations of each residential quarter, make the channel resource reasonable distribution between voice and data service, namely do not affect on the basis of user perceptibility, can effectively utilize Internet resources again, and can improve the technique effect that TBF is created as power.

Embodiment two

This enforcement provides a kind of method of TBF resource distribution, and the method is used under the preferential prerequisite of voice, and as shown in Figure 2, the method comprises:

Step 201, BSS gathers type and the achievement data of residential quarter from the traffic measurement data;

The base station need to obtain the above-mentioned type from the traffic measurement data and achievement data comprises at least: the scanning times of the traffic carrying capacity of EPDCH, the traffic carrying capacity of BPDCH, residential quarter TCH total traffic, residential quarter TCH configurable number, GPRS; And congestion ratio, TBF empties rate, half rate traffic ratio.

Step 202, BSS calculates according to the scanning times of the traffic carrying capacity of the traffic carrying capacity of the EPDCH in the above-mentioned type and achievement data, BPDCH, residential quarter TCH total traffic, the total configurable number of residential quarter TCH, GPRS the threshold value that is used for the TBF resource distribution;

Particularly, in the present embodiment, this threshold T BFxLLIMIT that determines can be divided into up TBF threshold T BFULLIMIT and descending TBF threshold T BFDLLIMIT.Therefore, correspondingly, above-mentioned BSS calculates according to the scanning times of the traffic carrying capacity of the traffic carrying capacity of EPDCH, BPDCH, residential quarter TCH total traffic, the total configurable number of residential quarter TCH, GPRS the threshold value that is used for the TBF resource distribution should specifically be divided into following two kinds of situations:

1, calculate according to the traffic carrying capacity of the traffic carrying capacity of up EPDCH, up BPDCH, residential quarter TCH total traffic, the total configurable number of residential quarter TCH, up GPRS scanning times the TBFULLIMIT that is used for the TBF resource distribution.Computational methods can be with reference to following formula one

$\mathrm{TBFULLIMIF}=10\×\mathrm{ABS}\left(\frac{\mathrm{ULTBFPEPDCH}+\mathrm{ULTBFPBPDCH}}{({\mathrm{TOTAL}}_{\mathrm{TCH}}-\mathrm{ERLANG}(A,0.002))\×\mathrm{TRAFFULGPRSSCAN}}\right)$ (1)

Wherein, TBFULLMIMIT represents up TBF threshold value, and ULTBFPEPDCH represents the traffic carrying capacity of up EPDCH, and ULTBFPBPDCH represents the traffic carrying capacity of up BPDCH, TOTAL _TCHRepresent residential quarter TCH configurable number, A represents residential quarter TCH total traffic, and TRAFFULGPRSSCAN represents up GPRS scanning times; ABS represents the function that takes absolute value, and ERLANG represents according to ERLANG B value function.

2, calculate according to the traffic carrying capacity of the traffic carrying capacity of descending EPDCH, descending BPDCH, residential quarter TCH total traffic, the total configurable number of residential quarter TCH, descending GPRS scanning times the TBFDLLIMIT that is used for the TBF resource distribution.Computational methods can be with reference to following formula two

$\mathrm{TBFDDLLIMIT}=10\×\mathrm{ABS}\left(\frac{\mathrm{DLTBFPEPDCH}+\mathrm{DLTBFPBPDCH}}{({\mathrm{TOTAL}}_{\mathrm{TCH}}-\mathrm{ERLANG}(A,0.002))\×\mathrm{TRAFFDLGPRSSCAN}}\right)$ (2)

Wherein, TBFDLLMIMIT represents descending TBF threshold value, and DLTBFPEPDCH represents the traffic carrying capacity of descending EPDCH, and DLTBFPBPDCH represents the traffic carrying capacity of descending BPDCH, TOTAL _TCHRepresent residential quarter TCH configurable number, A represents residential quarter TCH total traffic, and TRAFFDLGPRSSCAN represents descending GPRS scanning times; ABS represents the function that takes absolute value, and ERLANG represents according to ERLANG B value function.

The method of calculating TBFxLLMIMIT (being TBFDLLMIMIT and TBFULLMIMIT) is one of pith of the present embodiment, therefore below take the method for calculating TBFDLLMIMIT as example, specifically introduce the derivation of above-mentioned formula two.

During due to channel allocation in the voice priority scheme, at first distribute full rate TCH channel; Along with traffic increases, after the TCH channel of original free time is all occupied, with emptying the dynamic PDCH channel that takies, carry newly-increased traffic, start thresholding until reach half rate.After reaching half rate startup thresholding, newly-increased traffic empties dynamic PDCH with continuing, and newly-increased traffic will use half rate.So we can be divided into voice traffic channel with the TCH channel and be designated as CS _TCH, data traffic channels is designated as PS _PDCH

For the PS territory, if can gather TBF number that the PDCH number that distributes shares with each PDCH from the traffic measurement of GPRS/EDGE calculates and allows each TBF (TBF represents the user of a request msg business) when monopolizing a PDCH, therefore the PDCH number that needs need to first calculate descending total traffic (in like manner also can calculate up total traffic).

AllocatedPDCH number * descending PDCH reusing degree=descending TBF number (number of users)=descending PS _PDCH(1)

Owing to being each TBF of hypothesis situation of monopolizing a PDCH here, so the TBF number PDCH number in PS territory namely is also descending total traffic simultaneously.

Wherein, the PDCH number that the representative of Allocated PDCH number in above-mentioned formula (1) distributes, it comprises EPDCH channel and the BPDCH channel of distribution, and this part can be by the calculating of PDCH mean allocation quantity, and as for the EPDCH channel, formula is as follows:

Wherein, DLEPDH represents the quantity of descending EPDCH, and TRAFFDLGPRSSCAN represents descending GPRS scanning times.For BPDCH in like manner, be not repeated herein.

Descending PDCH reusing degree in above-mentioned formula (1) also is called sharing factor, is used for representing have what users sharing this PDCH on 1 PDCH.Owing to not having direct calculator to show on BSS, so descending PDCH reusing degree can calculate with following formula (3):

Wherein, DLTBFPBPDCH represents the traffic carrying capacity of descending BPDCH, DLTBFPGPDCH represents that the traffic carrying capacity of descending GPDCH is (because the traffic carrying capacity of general GPDCH is 0, so also can ignore), DLTBFPEPDCH represents the traffic carrying capacity of descending EPDCH, and DLBPDCH represents descending BPDCH number, and DLGPDCH represents that descending GPDCH number (is generally 0, can ignore), DLEPDCH represents descending EPDCH number.And that the descending PDCH reusing degree representative in formula (3) is EPDCH, BPECH, the average reusing degree of these three kinds of channels of GPDCH.In like manner also can derive up PDCH reusing degree, be not repeated herein.

In addition, owing to comprising for EPDCH in existing BSS, the difference of BPDCH is added up, and so for top descending PDCH reusing degree, descending EPDCH is namely calculated respectively in refinement more, the reusing degree of descending BPDCH, for example,

Then according in mean P DCH quantity allotted, calculate TBF business module quantity on each residential quarter.

Descending total traffic=EDGE traffic carrying capacity+gprs service amount (5)

Descending EDGE traffic carrying capacity=EPDCH mean allocation quantity+EPDCH reusing degree (6)

Descending gprs service amount=BPDCH mean allocation quantity+BPDCH reusing degree (7)

According to formula (1), (2) and (4), the equivalent formula that can derive formula (6) is:

So result of calculation is

In like manner can get

Can draw the following conclusions in sum:

In like manner,

Wherein, ULTBFPEPDCH represents up EPDCH number, and UPTBFPBPDCH represents up BPDCH number, and TRAFFULGPRSSCAN represents up GPRS scanning times.

On the other hand, for the CS territory, in the Cellular Networks system, 3 kinds of traffic concepts are arranged usually, voice provide traffic carrying capacity T _{Afferred_traffic}, voice service traffic carrying capacity T _{Served_traffic}, voice call loss traffic carrying capacity T _{Less_traffic}, the relation between these three kinds of amounts as shown in Figure 3,

Wherein,

T _{served_traffic}＝T _{afferred_traffic}+(1-GoS) (13)

Wherein, GoS represents the percent of call lost.

And then can obtain:

$T_{\mathrm{offerred\; traffic}}=\frac{T_{\mathrm{servedtraffic}}}{(1-\mathrm{GoS})}---\left(14\right)$

It is generally acknowledged for the full rate traffic:

${\mathrm{GoS}}_F\≈\frac{\mathrm{TFTHARDCONGS}}{3600}\%---\left(15\right)$

Wherein, the full rate congestion ratio after the TFTHARDCONGS representative empties.Because that use is TFTHARDCONGS, so the GoS here _FExpression be to have comprised the GoS that empties after PDCH under full rate; Get rid of and empty impact, can replace TFTHARDCONGS with the congestion ratio TFTCONGS under the normal condition full rate.Be namely:

${\mathrm{GoS}}_F\≈\frac{\mathrm{TFTCONGS}}{3600}\%---\left(16\right)$

So,

$F_{\mathrm{offerred}\_\mathrm{traffic}}=\frac{F_{\mathrm{served}\_\mathrm{traffic}}}{1-{\mathrm{GoS}}_F}---\left(17\right)$

Wherein, F _{Offerred_traffic}Represent that the voice under full rate provide traffic carrying capacity, F _{Servedd_traffic}Represent the voice service traffic carrying capacity under full rate, GoS _FRepresent the GoS under full rate.

In like manner, can obtain following formula for half rate traffic

${\mathrm{GoS}}_H\≈\frac{\mathrm{THTCONGS}}{3600}\%---\left(18\right),$

Wherein, GoS _HRepresent the GoS under half rate, THTCONGS represents the congestion ratio under half rate.

$H_{\mathrm{offerred}\_\mathrm{traffic}}=\frac{H_{\mathrm{served}\_\mathrm{traffic}}}{1-{\mathrm{GoS}}_H}---\left(19\right)$

Wherein, H _{Offerred_traffic}Represent that the voice under half rate provide traffic carrying capacity, H _{Servedd_traffic}Represent the voice service traffic carrying capacity under half rate, GoS _HRepresent the GoS under half rate.

Therefore, CS territory, whole residential quarter provides traffic carrying capacity Totalo _{Fferred_traffic},

Total _{offerred_traffic}＝F _{offerred_traffic}+H _{offerred_traffic}(20)

By existing ERLANG B (Erlang B table), can find and to support so large Total _{Offerred_traffic}Need how many TCH, i.e. CS _TCH

The result in CS territory and PS territory to sum up,

Total _TCH＝CS _TCH+PS _PDCH (21)

In channel allocation, at first guaranteeing under the preferential prerequisite of voice, the data traffic channels of distributing is PS_PDCH, comprise EPDCH, the channels such as BPDCH, for busy residential quarter, PDCH efficient desired value is approximately 4kbps-5kbps (group's desired value), the corresponding single PDCH flow of single busy 1.8MB-2.25MB (unified is 2MB) is if the sole user monopolizes BPDCH

According to gsm wireless data service resource distribution principle, in the shared mechanism of PDCH, each PDCH can be shared by 8 business at most, if network congestion is not especially severe, the access of service request is not had direct impact.The EDGE mobile phone allows alone family to take a plurality of time slots.Gprs system has been introduced the coded system of different wireless channels: CS-1, CS-2, CS-3 and CS-4, and data rate is followed successively by 9.05Kbps, 13.4Kbps, 15.6Kbps, 21.4Kbps, MSC-9 coding, 59.2kbit/s/EPDCH, much larger than the expected rate of PDCH.Multi-user user shares the PDCH channel, and the maximum reusing degree of single PDCH channel is TBFxLLIMIT.

At this, the TBF capacity that can set PDCH channel maximum is

TBF sum=PS _PDCHTBFxLLIMIT

According to formula 21Total _TCH=CS _TCH+ PS _PDCHAs can be known, preferential in order to guarantee voice, what should extract the residential quarter is statistical time range from busy, also obvious to tying up of data business because speech business this moment is the busiest, so this moment, the TBFxLLIMIT that calculates was the maximum of this residential quarter.Can calculate by ERLANG B, under the prerequisite of the percent of call lost 2%, carrying is A from the TCH traffic total amount of busy voice telephone traffic amount, and the so required number of channel is made as ERLANG (A, 0.02),

PS _PDCH＝TOTAL _TCH-ERLANG(A，0.02) (23)

So can get according to formula (22) and (23):

Descending TBF sum=(TOTAL _TCH-ERLANG (A, 0.02)) * TBFDLLIMIT (24)

Because descending total traffic should equate with descending TBF total amount, that is: descending total traffic=descending TBF sum (25), according to formula (25), formula (24) and (11) are brought into respectively and can be drawn:

$\mathrm{TBFDLLIMIT}=\frac{\mathrm{DLTBFPEPDCH}+\mathrm{DLTBFPBPDCH}}{({\mathrm{TOTAL}}_{\mathrm{TCH}}-\mathrm{ERLANG}(A,0.002))\×\mathrm{TRAFFDLGPRSSCAN}}---\left(25\right)$

Very busy for traffic, the data service also the possibility of result that draws of a lot of residential quarter has negative value, and this carrier frequency that shows the traffic carrying capacity that carrying is so large is greater than current configuration carrier frequency, thus we such value is taken absolute value without exception, that is:

$\mathrm{TBFDLLIMIT}=\mathrm{ABS}\frac{\mathrm{DLTBFPEPDCH}+\mathrm{DLTBFPBPDCH}}{({\mathrm{TOTAL}}_{\mathrm{TCH}}-\mathrm{ERLANG}(A,0.002))\×\mathrm{TRAFFDLGPRSSCAN}}---\left(26\right)$

Be 10 times of actual value due to parameter value, calculate so the result of formula (26) be multiply by 10, according to the mapping relations of TBFxLLIMIT, can obtain final above-mentioned formula two:

$\mathrm{TBFDLLIMIT}=10\×\mathrm{ABS}\left(\frac{\mathrm{DLTBFPEPDCH}+\mathrm{DLTBFPBPDCH}}{({\mathrm{TOTAL}}_{\mathrm{TCH}}-\mathrm{ERLANG}(A,0.002))\×\mathrm{TRAFFDLGPRSSCAN}}\right)$ (2)

In like manner can draw above-mentioned formula one:

$\mathrm{TBFULLIMIT}=10\×\mathrm{ABS}\left(\frac{\mathrm{ULTBFPEPDCH}+\mathrm{ULTBFPBPDCH}}{({\mathrm{TOTAL}}_{\mathrm{TCH}}-\mathrm{ERLANG}(A,0.002))\×\mathrm{TRAFFULGPRSSCAN}}\right)$ (1)

The whole process of this calculating can be completed automatically, the TBFxLLIMIT that calculates is namely the threshold value that is used for the TBF resource distribution of determining, and because the layoutprocedure of this threshold value is calculated automatically, the frequency of therefore adjusting TBFxLLIMIT also has dynamic.For example can one week adjust once this TBFxLLIMIT, also can adjust one time TBFxLLIMIT in one day, even adjustment in 2 hours once all can, not only efficient is high, reasonability is strong, also helps the reasonable distribution of channel resource between data and speech business.

Need to prove: the formula that can be used for calculating TBFxLLIMIT in the present embodiment is not limited to the form of above-mentioned formula one and formula two.The for example formula one after multiply by parameter X simultaneously on molecule and denominator or formula two.And because those skilled in the art all can to the formula one in the present embodiment and formula two be out of shape or equivalent transformation etc.; and obtain easily with the present embodiment in the formula of formula one or two same functions, so the formula after these distortion or equivalent transformation also should belong among protection scope of the present invention.

For reasonability and the accuracy that guarantees TBFxLLIMIT, after calculating threshold value for this TBFxLLIMIT by above-mentioned formula one or two in the present embodiment, also to proofread and correct according to other indexs of residential quarter.For example, for up TBF, consider whether to have paging congested, if having, need dilatation CCCH (Common Control Channel).And unsuitable excessive for arranging of TBFxLLIMIT, otherwise affect the PDCH bearer rate, affect client perception, too smallly can't provide the channel bearing user again, so the method for the present embodiment also comprises:

Step 203, at least one of emptying in rate and half rate traffic ratio according to the type of residential quarter and the congestion ratio in achievement data, TBF of BSS proofreaies and correct described threshold value;

Because needs are proofreaied and correct, also comprised congestion ratio in the type of the residential quarter that therefore gathers and achievement data in step 201, TBF empties rate, half rate traffic ratio;

Particularly, step 203 can realize (because this mode is all applicable for TBFDLLIMIT and TBFULLIMIT, therefore not distinguishing uplink and downlink in following narration process) in the following way:

When described threshold value is positioned at the first correcting area, determine the first coefficient according at least one item that described congestion ratio, TBF empty in rate and half rate traffic ratio, and according to described the first coefficient and described threshold value calculation correction threshold value;

When described threshold value is positioned at the second correcting area, determine the second coefficient according at least one item that described congestion ratio, TBF empty in rate and half rate traffic ratio, and according to described the second coefficient and described threshold value calculation correction threshold value;

When described threshold value is positioned at the 3rd correcting area, determine the 3rd coefficient according at least one item that described congestion ratio, TBF empty in rate and half rate traffic ratio, and according to described the 3rd coefficient and described threshold value calculation correction threshold value.

For example: the correction gate limit value of regulation TBFxLLIMIT is T ', and the span of setting T ' be [20,60], exceed or deficiency carry out polishing, make it reach the scope that we preset.Therefore, the first correcting area is that TBFxLLIMIT＜20%, the second correcting area is that 20%＜TBFxLLIMIT＜40%, the three correcting area is TBFxLLIMIT＞40%, and is corresponding, sets calibration principle such as following table one
