Embodiment

Fig. 1 is the flow chart of the acquisition methods embodiment one of wireless network utilance of the present invention, and as shown in Figure 1, the method for present embodiment can comprise:

Step 101, the ratio DVR that obtains data service telephone traffic and speech business telephone traffic, average every sub-district can use voice traffic channel TCHs, average every sub-district packets available data channel to count PDCHS, on average speech business capacity KV, average unbalance factor β during data service capacity KD, the speech business busy cells of each Packet Data Channel of each voice traffic channel _V, unbalance factor β during the data service busy cells _D

Wherein, the number of channel of M for comprising in carrier frequency of expression.

Specifically,, only consider that speech business can not reflect the situation of utilizing of Internet resources truly, therefore need know data service and speech business and deposit the real network utilance α under the situation along with developing rapidly of data service ₀, it defines as follows:

${\mathrm{\α}}_0=\frac{A_{V-\mathrm{total}}+A_{D-\mathrm{total}}}{\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{V}_i}$

Wherein, A _V-totalSpeech business total traffic during the expression system busy, A _D-totalData service total traffic during the expression system busy, finger speech sound business telephone traffic and data service telephone traffic sum are maximum one hour during system busy, and N representes the whole network sub-district sum, V _iRepresent the speech business that i sub-district is actual available and the total capacity of data service.The computational methods of this speech business capacity can be each sub-districts according to its actual available voice traffic channel (hereinafter to be referred as TCH) number; Looking into the ERL-B table obtains; Should calculate according to the ERL-C formula on the theory of computation of data service capacity, its parameter that relates to comprises the number of channel, average delay, bag length, telephone traffic etc.But the calculating of above-mentioned formula adds up after need calculating each sub-district, calculates to show complicated slightly.

The inventor has carried out data statistic analysis to the speech business traffic capacity, and the result is as shown in table 1:

Every channel speech business traffic capacity situation of change when the different carrier frequency of table 1 dispose

The carrier frequency number	The TCH number of channel	The speech business traffic capacity	Average every channel speech business traffic capacity
				1	6	2.276	0.38
2	14	8.200	0.59
				3	21	14.036	0.67
4	28	20.150	0.72
				5	36	27.343	0.76
6	43	33.758	0.79
				7	51	41.189	0.81
8	58	47.758	0.82

Find through statistical analysis, when the carrier frequency of cell configuration more after a little while, it is more accurate to adopt the ERL-B table to calculate its speech business Capacity Ratio because the number of channel of every sub-district is limited, the speech business capacity of every channel changes greatly with the number of channel; When the carrier frequency of cell configuration was higher, the speech business capacity of every channel changed little with the number of channel.

Can find out that from last table 1 when the carrier frequency configuration was low, for example cell configuration was when three carrier frequency are following, the variation of the speech business traffic capacity of average every channel is at 0.38erl/tch---and 0.67erl/tch changes bigger; And dispose when higher when carrier frequency; For example cell configuration is when three carrier frequency are above, and the variation of the speech business traffic capacity of average every channel is at 0.67erl/tch---and 0.82erl/tch changes less; And when network configuration is higher; Operator also requires network that certain capability of overload is arranged, and does not hope that every channel load is too high, can adopt this moment the number of channel to multiply by the professional traffic capacity of every channel speech business traffic capacity computing voice.

In like manner; When the PDCH of cell configuration more after a little while, it is comparatively accurate to adopt the ERL-C table to calculate its data service traffic capacity, when the data traffic channels of cell configuration more for a long time; The data service traffic capacity of every channel changes little with the number of channel, concrete statistical content sees following table 2 for details:

The professional traffic capacity situation of change of every channel data during table 2 different pieces of information traffic channel configuration

The number of channel	Average delay	Bag is long	Telephone traffic	The K value
					N	D1 (unit second)	S (unit second)	A（ERL）	Every channel telephone traffic
1	0.01	0.02	0.33	0.333
					2	0.01	0.02	1.15	0.577
3	0.01	0.02	2.06	0.686
					4	0.01	0.02	2.99	0.747
5	0.01	0.02	3.94	0.788
					6	0.01	0.02	4.9	0.816

As can be seen from Table 2, when carrier frequency disposes when higher, can adopt the number of channel to multiply by the professional traffic capacity of every channel data and come the professional traffic capacity of calculated data.

Therefore when the high configuration of network, the speech business that i sub-district reality is available and the total capacity V of data service _iCan use computes:

V _i=TCH _i×K _V+PDCH _i×K _D

Wherein, TCH _iThe available TCH number of representing i sub-district; PDCH _iThe available PDCH number of representing i sub-district; K _VThe speech business capacity that average each the TCH channel of expression can provide, value can be between 0.6 ~ 0.8, and for ease of calculating, a local network can be according to the actual conditions of self, and a value is got in unification; K _VCan calculate with the speech business traffic capacity of the whole network available TCH number, when the network configuration of a local network does not have under the situation of big change K than last the whole network _VValue change little, can think definite value; K _DThe data service capacity that average each the PDCH channel of expression can provide, value can be between 0.6 ~ 0.8, and for ease of calculating, a local network can be according to the actual conditions of self, a unified value, the K of getting _DCan calculate with the data service traffic capacity of the whole network available PDCH number, when the network configuration of a local network does not have under the situation of big change K than last the whole network _DValue change little, can think definite value.

Based on above-mentioned statistical analysis, can obtain the real network utilance α shown in following ₀Computing formula (3);

${\mathrm{\α}}_0=\frac{A_{V-\mathrm{ave}}+A_{D-\mathrm{ave}}}{{\mathrm{TCH}}_S\×K_V+{\mathrm{PDCH}}_S\×K_D}---\left(3\right).$

When concrete the realization, can obtain average every cell system speech business telephone traffic A when busy _V-ave, data service telephone traffic A when average every cell system is busy _D-ave, average every sub-district can use voice traffic channel TCH _s, average every sub-district packets available data channel counts PDCH _S, the average speech business capacity K of each speech data channel _V, the average speech business capacity K of each Packet Data Channel _D, wherein said average, be average divided by the whole network sub-district number, then, can adopt formula (3) to calculate and obtain real network utilance α ₀

Further; Adopt the real network utilance during the busy not busy degree of the wireless network of operator's assessment at present mostly; Multiple factors such as the total traffic of this real network utilance and various places, traffic density, traffic distribution, population, economy, geographical environment are relevant; Its numerical value can reflect the load variations of this network different time, but can not be used for to carrying out lateral comparison between different districts and cities.So-called network utilization rationally is under the known situation of traffic demand, and it is the most reasonable how network capacity disposes.Reasonably network capacity should be that snugly satisfies traffic demand in a period of time, promptly can satisfy the traffic demand of each sub-district and removable off-load frequency not more than needed.Thus, speech business total traffic A in the time of can passing through system busy _V-total, data service total traffic A during system busy _D-total, the whole network sub-district counts speech business capacity and the data service capacity sum C that N, each sub-district need dispose _iCalculate and obtain this reasonable network utilization α, concrete calculating can adopt formula (4) to realize:

$\mathrm{\α}=\frac{A_{V-\mathrm{total}}+A_{D-\mathrm{total}}}{\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{C}_i}---\left(4\right).$

Referring again to the given statistical analysis of above-mentioned table 1 and table 2 can know, during the high configuration of network, the speech business capacity that the sub-district need dispose and the computational methods of data service capacity can for:

Each sub-district is speech business telephone traffic A during according to its busy cells _V-iDivided by COEFFICIENT K _VObtain the voice traffic channel number that it need dispose, each sub-district is data service telephone traffic A during according to its busy cells _D-iDivided by COEFFICIENT K _DObtain the Packet Data Channel number that it need dispose, wherein, K _VBe the speech business capacity of average each TCH, K _DData service capacity for average each Packet Data Channel.

Then, voice traffic channel number that obtains and Packet Data Channel are counted after the addition big or small, also, can be obtained the carrier frequency number, again this carrier frequency number is rounded up promptly divided by a number of channel M that carrier frequency comprised divided by the BTS channel processing module; Because when the configuration carrier frequency; Its step-length is a M channel, and therefore, the present invention can be according to speech business principle of priority in the existing network; Cause the number of channel of polygamy to distribute to speech business rounding up, other channel then can be pro rata distributed between speech business and data service; The number of channel that last speech business and data service distribute multiply by COEFFICIENT K respectively _VAnd COEFFICIENT K _DObtain the traffic capacity of its actual needs configuration.

Based on above-mentioned analysis, the C in the formula (4) _iSpecifically can adopt formula (5) to calculate obtains:

$C_i=A_{V-i}+A_{D-i}+\left\{\mathrm{ROUNDUP}\right[\frac{A_{V-i}/K_V+A_{D-i}/K_D}{M}]-\frac{A_{V-i}/K_V+A_{D-i}/K_D}{M}\}\×M\×K_V---\left(5\right)$

Wherein, M representes the number of channel that comprises in the carrier frequency, and ROUNDUP is the function that rounds up.For instance, in gsm system, comprise 8 channels in the carrier frequency.

K _VThe speech business capacity that average each the TCH channel of expression can provide, value can be between 0.6 ~ 0.8, and for ease of calculating, a local network can be according to the actual conditions of self, and a value is got in unification; K _VCan calculate with the TCH number than last the whole network with the speech business traffic capacity, when the network configuration of a local network does not have under the situation of big change K _vValue change little, can think definite value; K _DThe data service capacity that average each PDCH of expression can provide, value can be between 0.6 ~ 0.8, and for ease of calculating, a local network can be according to the actual conditions of self, and a value is got in unification; K _DCan calculate with the PDCH number than last the whole network with the data service traffic capacity, when the network configuration of a local network does not have under the situation of big change K _DValue change little, can think definite value.

Need to prove; Because present most of network has all been opened half rate; And the half rate telephone traffic accounting in the subnetwork is bigger; In order to reflect the situation of utilizing of Internet resources more exactly, when computing system is busy, can consider by half the half rate telephone traffic during speech business total traffic, i.e. half rate traffic telephone traffic/2 during full rate telephone traffic during speech business telephone traffic during system busy=system busy+system busy.

When concrete the realization, the inventor further finds, when bringing above-mentioned formula (5) into the middle calculating of above-mentioned formula (4) reasonable network utilization, need carry out the summation of N sub-district and handle, and computational process is comparatively loaded down with trivial details.In order to reduce amount of calculation, the inventor has carried out further improvement to the computing formula of above-mentioned formula (5) being brought into behind the formula (4), adopts following formula (6) to calculate and obtains reasonable network utilization α:

$\mathrm{\α}=\frac{A_{V-\mathrm{ave}}+A_{D-\mathrm{ave}}}{A_{V-\mathrm{ave}}\×{\mathrm{\β}}_V+A_{D-\mathrm{ave}}\×{\mathrm{\β}}_D+M/2\×K_V}---\left(6\right)$

Wherein, A _V-aveSpeech business telephone traffic when hurrying for average every cell system, A _D-aveData service telephone traffic when hurrying for average every cell system, β _VUnbalance factor during for the speech business busy cells, β _DUnbalance factor during for the data service busy cells, M are represented the number of channel that comprises in the carrier frequency, K _VSpeech business capacity for average each voice traffic channel.

Specifically, with said A _V-totalDivided by said N, can obtain said A _V-aveWith said A _D-totalDivided by said N, can obtain said A _D-aveSaid speech business traffic capacity can be used the voice traffic channel number divided by the whole network, can obtain said K _VSpeech business telephone traffic is divided by A during with busy cells _V-total, can obtain said β _VThe data service telephone traffic is divided by A during with busy cells _D-total, can obtain said β _D

After having obtained reasonable network utilization, the real network utilance that just can utilize aforementioned formula (3) to calculate to obtain and formula (6) calculate the difference acquisition wireless network overloading ratio Δ α=α of the reasonable network utilization that obtains ₀-α) carry out lateral comparison between different districts and cities, the province, and can calculate current network and need increase the wireless network capacitance of joining.

Δ α weighs the not busy index of network busy, when Δ α when negative, represent that present network is relatively notr busy, traffic still has room for promotion, can promote telephone traffic through means such as telephone traffic marketing and increase, thus the utilance of lifting existing network.When Δ α is zero, represent that the network configuration of current telephone traffic and reality is mated just, be the state of network resource usage fullest.When Δ α is correct time, represent that present network is busier, the wireless network capacitance configuration is not enough, need satisfy current traffic demand through dilatation.

The overloading ratio definition can know that when overloading ratio Δ α was zero, the capacity of wireless network just satisfied business demand, neither needs dilatation, does not also have the removable carrier frequency that subtracts, and is the state that Radio Resource utilizes fullest from the front.Therefore, from utilization of resources angle, the network utilization that present embodiment has defined when overloading ratio is zero is the objective network utilance.

According to the approximate formula of comprehensive real network utilance with reasonable network utilization; Be formula (3) and formula (6); Make these two formula equate, and the ratio DVR of professional telephone traffic of setting data and speech business telephone traffic, the approximate formula that then can derive the objective network utilance is following:

${\mathrm{\α}}_1=\frac{(1+\mathrm{DVR})\×\{({\mathrm{Tch}}_S-M/2)\×K_V+{\mathrm{PDCH}}_S\×K_D\}}{({\mathrm{Tch}}_S\×K_V+{\mathrm{PDCH}}_S\×K_D)\×({\mathrm{\β}}_V+\mathrm{DVR}\×{\mathrm{\β}}_D)}---\left(1\right)$

If K _VValue and K _DValue is identical, and then following formula can be reduced to following formula:

${\mathrm{\α}}_1=\frac{(1+\mathrm{DVR})\×({\mathrm{Tch}}_S-M/2+{\mathrm{PDCH}}_S)}{({\mathrm{Tch}}_S+{\mathrm{PDCH}}_S)\×({\mathrm{\β}}_V+\mathrm{DVR}\×{\mathrm{\β}}_D)}---\left(7\right)$

When concrete the realization, adopt formula (1) or formula (7) to obtain before the objective network utilance, can carry out following preprocessing process:

The whole network can be obtained said TCH with the voice traffic channel number divided by said the whole network sub-district number _s

The whole network packets available data channel number divided by said the whole network sub-district number, is obtained said PDCH _S

The speech business traffic capacity can be used the voice traffic channel number divided by said the whole network, obtain said K _V

The data service telephone traffic obtained said β when the data service telephone traffic was divided by system busy during with busy cells _D

Therefore, present embodiment is to the situation that has speech business and data service in the high configuration network simultaneously, through DVR, TCHs, the PDCH that obtains _S, K _V, K _D, β _VAnd β _DCan calculate the objective network utilance of acquisition system, and this computational process is on the basis to the statistical analysis of speech business traffic capacity and data service traffic capacity, to carry out, it calculates simple; And the result is accurate, can reflect the target network resource configuration that system is required comparatively objectively.

After employing the foregoing description obtains the objective network utilance, can also adopt following formula (2) to obtain wireless network goal discrepancy Δ α ₀:

Wherein, α ₀Be real network utilance, α ₀Adopting formula (3) to calculate obtains.

Δ α ₀Be to weigh the not busy index of network busy.As Δ α ₀>0 o'clock, represent the best telephone traffic that current telephone traffic can be carried greater than network, network is busy partially; As Δ α ₀<0, represent the best telephone traffic that current telephone traffic can be carried less than network, network is idle partially, and current network still has certain telephone traffic room for promotion; As Δ α ₀=0, current telephone traffic is mated with actual network configuration just, is the state of network resource usage fullest.

This wireless network goal discrepancy Δ α ₀Can when the network planning and adjustment, have following function:

As Δ α ₀<0 o'clock, traffic still had room for promotion, and can promote telephone traffic through means such as telephone traffic marketing and increase, thus the utilance of lifting existing network.The computing formula of traffic room for promotion is as follows during system busy:

Telephone traffic during traffic room for promotion during system busy=existing network wireless capacity * objective network utilance-existing network system busy.

As Δ α ₀=0 o'clock, represent that the network configuration of current telephone traffic and reality is mated just, be the state of network resource usage fullest.

As Δ α ₀>0 o'clock, represent that present network is busier, the wireless network capacitance configuration is not enough, need satisfy current traffic demand through dilatation, and the computing formula that need increase the wireless capacity of joining is as follows:

Network utilization-existing network the wireless capacity of telephone traffic in the time of need increasing the wireless capacity of joining=existing network system busy/rationally.

Telephone traffic refers to speech business telephone traffic and data service telephone traffic sum when it should be noted that the existing network system busy, and the existing network wireless capacity refers to speech business capacity and data service capacity sum.

In addition, for Δ α ₀>0 province can be with the up to standard value of reasonable network utilization as its network utilization;

For Δ α ₀Province between-5% ~ 0% can be directly with the up to standard value of objective network utilance as network utilization;
