Embodiment

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

Step 101, the ratio DVR obtaining data service telephone traffic and speech business telephone traffic, average every community available speech Traffic Channel TCH _s, average every community available packet data number of channel PDCH _s, the voice-service capacity KV of average each voice traffic channel, average each Packet Data Channel data service capacity KD, speech business busy cells time unbalance factor β _v, data service busy cells time unbalance factor β _d;

Step 102, employing formula (1) calculate and obtain objective network utilance α ₁

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

Wherein, M is the number of channel comprised in expression carrier frequency.

Specifically, along with developing rapidly of data service, only consider that speech business can not reflect the utilization power of Internet resources truly, therefore need to know data service and speech business and real network utilance α under depositing situation ₀, it is defined 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 expression system busy, A _d-totaldata service total traffic when representing system busy, refer to speech business telephone traffic and maximum one hour of data service telephone traffic sum during system busy, N represents the whole network community sum, V _irepresent the total capacity of the actual available speech business in i-th community and data service.The computational methods of this voice-service capacity can be each communities according to its actual available speech Traffic Channel (hereinafter referred to as TCH) number, look into ERL-B table to obtain, the theory of computation of data service capacity should calculate according to ERL-C formula, and its parameter related to comprises the number of channel, average delay, bag length, telephone traffic etc.But the calculating of above-mentioned formula needs to add up to after the calculating of each community, calculate slightly aobvious complicated.

Inventor has carried out data statistic analysis for speech business traffic capacity, and result is as shown in table 1:

Every channels voice business traffic capacity situation of change during the different carrier configuration of table 1

Carrier frequency number	The TCH number of channel	Speech business traffic capacity	Average every channels voice 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

Found by statistical analysis, when the carrier frequency of cell configuration is less, adopt ERL-B table to calculate its voice-service capacity relatively more accurate, because the number of channel of every community is limited, the voice-service capacity of every channel changes greatly with the number of channel; When the carrier frequency of cell configuration is higher, the voice-service capacity of every channel is little with number of channel change.

As can be seen from Table 1, when carrier configuration is lower, such as, when cell configuration is below three carrier frequency, the change of the speech business traffic capacity of average every channel is at 0.38erl/tch---and 0.67erl/tch, changes greatly; And when carrier configuration is higher, such as, when cell configuration is more than three carrier frequency, the change of the speech business traffic capacity of average every channel is at 0.67erl/tch---0.82erl/tch, change less, and when network configuration is higher, operator also requires that network has certain capability of overload, does not wish that every channel load is too high, the number of channel now can be adopted to be multiplied by every channels voice business traffic capacity and calculate speech business traffic capacity.

In like manner, when the PDCH of cell configuration is less, ERL-C table is adopted to calculate its data service traffic capacity comparatively accurate, when the data traffic channels of cell configuration is more, the data service traffic capacity of every channel is little with number of channel change, and concrete statistical content refers to following table 2:

Every channel data traffic traffic capacity situation of change during table 2 different pieces of information traffic channel configuration

The number of channel	Average delay	Bag is long	Telephone traffic	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 configuration is higher, the number of channel can be adopted to be multiplied by every channel data traffic traffic capacity and to carry out calculated data business traffic capacity.

Therefore when the configuration of network height, the total capacity V of i-th actual available speech business in community and data service _ican calculate with following formula:

V _i＝TCH _i×K _V+PDCH _i×K _D

Wherein, TCH _irepresent the available TCH number of i-th community; PDCH _irepresent the available PDCH number of i-th community; K _vrepresent the voice-service capacity that average each TCH channel can provide, value can between 0.6 ~ 0.8, and for ease of calculating, a local network can according to the actual conditions of self, and a value is got in unification; K _vcan calculate with the available TCH number of the speech business traffic capacity of the whole network than upper the whole network, when the network configuration of a local network does not have large variation, K _vvalue variation little, can definite value be thought; K _drepresent the data service capacity that average each PDCH channel can provide, value can between 0.6 ~ 0.8, and for ease of calculating, a local network can according to the actual conditions of self, and unification gets a value, K _dcan calculate with the available PDCH number of the data service traffic capacity of the whole network than upper the whole network, when the network configuration of a local network does not have large variation, K _dvalue variation little, can definite value be thought.

Based on above-mentioned statistical analysis, following shown real network utilance α can be obtained 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 specific implementation, average every cell system busy speech business telephone traffic A can be obtained _v-ave, average every cell system busy data service telephone traffic A _d-ave, average every community available speech Traffic Channel TCH _s, average every community available packet data number of channel PDCH _s, average each speech data channel voice-service capacity K _v, average each Packet Data Channel voice-service capacity K _d, wherein said is average, and what be divided by the whole network community number is average, then, formula (3) can be adopted to calculate and obtain real network utilance α ₀.

Further, real network utilance is mostly adopted during current operator's assessment wireless network busy degree, the total traffic of this real network utilance and various places, traffic density, traffic distribute, the many factors such as population, economy, geographical environment is relevant, its numerical value can reflect the load variations of this network different time, but can not be used for carrying out lateral comparison between different districts and cities.So-called rationally network utilization, be when traffic demand is known, it is the most reasonable how network capacity configures.Rational network capacity should be that snugly meets traffic demand in a period of time, namely can meet the traffic demand of each community and removable off-load frequency not more than needed.Thus, can by speech business total traffic A during system busy _v-total, system busy time data service total traffic A _d-total, the whole network community number N, each community need configuration voice-service capacity and data service capacity sum C _icalculate and obtain this reasonable network utilization α, concrete calculating can adopt formula (4) to realize:

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

The statistical analysis referred again to given by above-mentioned table 1 and table 2 is known, and during the configuration of network height, the voice-service capacity of community needs configuration and the computational methods of data service capacity can be:

Each community is according to speech business telephone traffic A during its busy cells _v-idivided by COEFFICIENT K _vobtain the voice traffic channel number that it needs configuration, each community is according to data service telephone traffic A during its busy cells _d-idivided by COEFFICIENT K _dobtain the Packet Data Channel number that it needs configuration, wherein, K _vfor the voice-service capacity of average each TCH, K _dfor the data service capacity of average each Packet Data Channel.

Then, divided by BTS channel processing module size after the voice traffic channel number obtained and Packet Data Channel number are added, also namely divided by the number of channel M that a carrier frequency comprises, carrier frequency number can be obtained, then this carrier frequency number is rounded up; Due to when configuring carrier frequency, its step-length is M channel, and therefore, the present invention can according to the preferential principle of speech business in 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 is multiplied by COEFFICIENT K respectively _vand COEFFICIENT K _dobtain the traffic capacity of its actual needs configuration.

Based on above-mentioned analysis, the C in formula (4) _iformula (5) specifically can be adopted to calculate obtain:

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

Wherein, M represents the number of channel comprised in a carrier frequency, and ROUNDUP is the function that rounds up.For example, in gsm system, 8 channels in a carrier frequency, are comprised.

K _vrepresent the voice-service capacity that average each TCH channel can provide, value can between 0.6 ~ 0.8, and for ease of calculating, a local network can according to the actual conditions of self, and a value is got in unification; K _vcan calculate with TCH number than upper the whole network with speech business traffic capacity, when the network configuration of a local network does not have large variation, K _vvalue variation little, can definite value be thought; K _drepresent the data service capacity that average each PDCH can provide, value can between 0.6 ~ 0.8, and for ease of calculating, a local network can according to the actual conditions of self, and a value is got in unification; K _dcan calculate with PDCH number than upper the whole network with data service traffic capacity, when the network configuration of a local network does not have large variation, K _dvalue variation little, can definite value be thought.

It should be noted that, because present most of network has all opened half rate, and half rate telephone traffic accounting in subnetwork is larger, in order to reflect the utilization power of Internet resources more exactly, can consider by half half rate telephone traffic when computing system busy speech business total traffic, i.e. half rate traffic telephone traffic/2 during full rate telephone traffic+system busy during speech business telephone traffic=system busy during system busy.

When specific implementation, inventor finds further, and when above-mentioned formula (5) being brought into the reasonable network utilization of calculating in above-mentioned formula (4), need the summation process carrying out N number of community, computational process is comparatively loaded down with trivial details.In order to reduce amount of calculation, inventor has carried out further improvement to the computing formula after bringing above-mentioned formula (5) into 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-avefor average every cell system busy speech business telephone traffic, A _d-avefor average every cell system busy data service telephone traffic, β _vfor unbalance factor during speech business busy cells, β _dfor unbalance factor during data service busy cells, M represents the number of channel comprised in a carrier frequency, K _vfor the voice-service capacity of average each voice traffic channel.

Specifically, by described A _v-totaldivided by described N, described A can be obtained _v-ave; By described A _d-totaldivided by described N, described A can be obtained _d-ave; By institute's voice traffic traffic capacity divided by the whole network available speech Traffic Channel number, described K can be obtained _v; By speech business telephone traffic during busy cells divided by A _v-total, described β can be obtained _v; By data service telephone traffic during busy cells divided by A _d-total, described β can be obtained _d.

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

△ α is the index weighing network busy, and when △ α is for time negative, represent that current network is notr busy, traffic still has room for promotion, can promote telephone traffic and increase, thus promote the utilance of existing network by means such as telephone traffic marketing.When △ α is zero, representing that current telephone traffic and actual network configuration are mated just, is the most sufficient state of network resource usage.When △ α is timing, represent that current network is busier, wireless network capacitance configuration is not enough, needs to meet current traffic demand by dilatation.

From overloading ratio definition above, when overloading ratio △ α is zero, the capacity of wireless network just meets business demand, neither needs dilatation, does not also have the removable carrier frequency subtracted, and is that Radio Resource utilizes the most sufficient state.Therefore, from utilization of resources angle, the present embodiment network utilization defined when overloading ratio is zero is objective network utilance.

According to the approximate formula of comprehensive real network utilance and reasonable network utilization, i.e. formula (3) and formula (6), make these two formula equal, and the ratio DVR of setting data business telephone traffic and speech business telephone traffic, then the approximate formula can deriving objective network utilance is as follows:

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

If K _vvalue and K _dvalue is identical, then above 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 specific implementation, before adopting formula (1) or formula (7) acquisition objective network utilance, can following preprocessing process be carried out:

By the whole network available speech Traffic Channel number divided by described the whole network community number, obtain described TCH _s;

By the whole network available packet data number of channel divided by described the whole network community number, obtain described PDCH _s;

By speech business traffic capacity divided by described the whole network available speech Traffic Channel number, obtain described K _v;

By data service traffic capacity divided by described the whole network available data traffic channels number, obtain described K _d; By speech business telephone traffic during busy cells divided by speech business total traffic during system busy, obtain described β _v;

By data service telephone traffic during busy cells divided by data service telephone traffic during system busy, obtain described β _d.

Therefore, the present embodiment, for the situation that there is speech business and data service in high configuration network simultaneously, by DVR, TCH of obtaining _s, PDCH _s, K _v, K _d, β _vand β _dcan calculate the objective network utilance of acquisition system, and this computational process is carried out on the basis of the statistical analysis to speech business traffic capacity and data service traffic capacity, it calculates simple, and result is accurate, the target network resource configuration needed for system can be reflected comparatively objectively.

After employing above-described embodiment obtains objective network utilance, following formula (2) can also be adopted to obtain wireless network goal discrepancy △ α ₀:

△α ₀＝α ₀-α ₁ (2)

Wherein, α ₀for real network utilance, α ₀adopt formula (3) to calculate to obtain.

△ α ₀it is the index weighing network busy.As △ α ₀during >0, represent the best telephone traffic that current telephone traffic is greater than network and can carries, network is partially busy; As △ α ₀<0, represent the best telephone traffic that current telephone traffic is less than network and can carries, network is partially idle, and current network still has certain telephone traffic room for promotion; As △ α ₀=0, current telephone traffic and actual network configuration are mated just, are the most sufficient states of network resource usage.

This wireless network goal discrepancy △ α ₀following function can be had when the network planning and adjustment:

As △ α ₀during <0, traffic still has room for promotion, can promote telephone traffic and increase, thus promote the utilance of existing network by means such as telephone traffic marketing.During system busy, the computing formula of traffic room for promotion is as follows:

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

As △ α ₀when=0, representing that current telephone traffic and actual network configuration are mated just, is the most sufficient state of network resource usage.

As △ α ₀during >0, represent that current network is busier, wireless network capacitance configuration is not enough, needs to meet current traffic demand by dilatation, needs the computing formula increasing the wireless capacity of joining as follows:

Telephone traffic when needing to increase the wireless capacity=existing network system busy of joining/rationally network utilization-existing network wireless capacity.

When it should be noted that existing network system busy, telephone traffic refers to speech business telephone traffic and data service telephone traffic sum, and existing network wireless capacity refers to voice-service capacity and data service capacity sum.

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

For △ α ₀province between-5% ~ 0%, can value up to standard directly using objective network utilance as network utilization;

For △ α ₀province between-10% ~-5%, the value up to standard of network utilization can be real network utilance+| △ α ₀|/2

For △ α ₀province between-25 ~-10%, the value up to standard of network utilization be real network utilance+| △ α ₀|/3.
