Description

Method for acquiring wireless network utilization rate and network management equipment

技术领域 technical field

本发明涉及无线网络技术，尤其涉及一种无线网络利用率的获取方法和网管设备，属于通信技术领域。The invention relates to wireless network technology, in particular to a method for obtaining the utilization rate of a wireless network and network management equipment, and belongs to the field of communication technology.

背景技术 Background technique

目前，运营商在运营无线通信网络，例如全球移动通信系统（GlobalSystem for Mobile Communications，以下简称：GSM）网络时，需要采用无线网络利用率这一指标来评估网络资源使用状态。At present, when operators operate wireless communication networks, such as the Global System for Mobile Communications (Global System for Mobile Communications, hereinafter referred to as: GSM) network, they need to use the indicator of wireless network utilization to evaluate the status of network resource usage.

现有技术采用下述公式计算得到传统的无线网络利用率R_w，从而根据该无线网络利用率对网络资源的使用状态进行评估：The prior art uses the following formula to calculate the traditional wireless network utilization rate R _w , so as to evaluate the usage status of network resources according to the wireless network utilization rate:

${R R}_{w w} = = \frac{{M m}_{h h} + + {M m}_{s the s}}{{N N}_{x x} K K}$

其中，M_h为语音业务量，M_s为数据业务量，N_x为业务信道数，N_x＝N_z×6.67，N_z为配置载频数，6.67表示的是平均每个载频的业务信道数。M_s定义为激活的分组数据信道（Packet Data Channel，以下简称：PDCH）占用时长折算为爱尔兰，即PDCH平均占用时长除以3600秒；K值表示的是平均每个业务信道能够承载的无线容量。Among them, M _h is the volume of voice traffic, M _s is the traffic volume of data, N _x is the number of traffic channels, N _x = N _z × 6.67, N _z is the number of configured carrier frequencies, and 6.67 represents the average traffic channel of each carrier frequency number. M _s is defined as the active packet data channel (Packet Data Channel, hereinafter referred to as: PDCH) occupation time converted to Ireland, that is, the average PDCH occupation time divided by 3600 seconds; K value represents the average wireless capacity that each traffic channel can carry .

但是，针对高配置网络中同时存在语音业务和数据业务的情况来说，上述计算方式仅是简单地将语音业务量和数据业务量之和与全部业务信道上所能承载的无线容量相比来得到无线网络利用率，其并不能准确反映当前网络配置下的目标网络利用率，针对如何获取目标网络利用率，现有技术并无解决方案。However, for the situation where there are both voice services and data services in a high-configuration network, the above calculation method simply compares the sum of the voice service volume and data service volume with the wireless capacity that can be carried on all service channels Obtaining the utilization rate of the wireless network cannot accurately reflect the target network utilization rate under the current network configuration, and there is no solution in the prior art for how to obtain the target network utilization rate.

具体实施方式 Detailed ways

图1为本发明无线网络利用率的获取方法实施例一的流程图，如图1所示，本实施例的方法可以包括：FIG. 1 is a flow chart of Embodiment 1 of the method for obtaining wireless network utilization in the present invention. As shown in FIG. 1, the method of this embodiment may include:

步骤101、获取数据业务话务量与语音业务话务量的比例DVR、平均每小区可用语音业务信道TCHs、平均每小区可用分组数据信道数PDCHS、平均每个语音业务信道的语音业务容量KV、平均每个分组数据信道的数据业务容量KD、语音业务小区忙时不均衡系数β_V、数据业务小区忙时不均衡系数β_D；Step 101, obtain the ratio DVR of data traffic volume and voice traffic volume, the average voice traffic channel TCHs available in each cell, the average number of packet data channels available in each cell PDCHS, the average voice traffic capacity KV of each voice traffic channel, The average data service capacity KD of each packet data channel, the unbalanced coefficient β _V of the voice service cell when it is busy, and the unbalanced coefficient β _D when the data service cell is busy;

步骤102、采用公式（1）计算获取目标网络利用率α₁ Step 102. Use the formula (1) to calculate and obtain the target network utilization rate α ₁

具体来说，随着数据业务的迅速发展，仅考虑语音业务已不能真实地反映网络资源的利用情况，因此需要获知数据业务和语音业务并存情况下的实际网络利用率α₀，其定义如下：Specifically, with the rapid development of data services, considering only voice services can no longer truly reflect the utilization of network resources, so it is necessary to know the actual network utilization rate α ₀ under the coexistence of data services and voice services, which is defined as follows:

${α α}_{00} = = \frac{{A A}_{V V - - total total} + + {A A}_{D D. - - total total}}{{Σ Σ}_{i i = = 11}^{N N} {V V}_{i i}}$

其中，A_V-total表示系统忙时语音业务总话务量，A_D-total表示系统忙时数据业务总话务量，系统忙时指语音业务话务量和数据业务话务量之和最大的一个小时，N表示全网小区总数，V_i表示第i个小区实际可用的语音业务和数据业务的总容量。该语音业务容量的计算方法可以是每个小区根据其实际可用语音业务信道（以下简称：TCH）数，查ERL-B表得到，数据业务容量的计算理论上应根据ERL-C公式进行计算，其涉及的参数包括信道数、平均时延、包长、话务量等。但是，上述公式的计算需要对每个小区计算后进行累加，计算稍显复杂。Among them, A _V-total indicates the total traffic volume of the voice service when the system is busy, A _D-total indicates the total traffic volume of the data service when the system is busy, and the time when the system is busy refers to the maximum sum of voice service traffic and data service traffic N represents the total number of cells in the entire network, and V _i represents the total capacity of voice services and data services actually available in the i-th cell. The calculation method of the voice service capacity can be obtained by looking up the ERL-B table according to the actual number of available voice service channels (hereinafter referred to as: TCH) in each cell. The calculation of the data service capacity should be calculated theoretically according to the ERL-C formula. The parameters involved include the number of channels, average delay, packet length, and traffic volume. However, the calculation of the above formula needs to be accumulated after calculation for each cell, and the calculation is slightly complicated.

发明人针对语音业务话务容量进行了数据统计分析，结果如表1所示：The inventor has carried out statistical analysis of the data for the voice service traffic capacity, and the results are as shown in Table 1:

表1不同载频配置时每信道语音业务话务容量变化情况Table 1 Changes in the traffic capacity of voice services per channel under different carrier frequency configurations

载频数 Carrier frequency TCH信道数 Number of TCH channels 语音业务话务容量 Voice service traffic capacity 平均每信道语音业务话务容量 Average voice traffic capacity per channel 1 1 6 6 2.276 2.276 0.38 0.38 2 2 14 14 8.200 8.200 0.59 0.59 3 3 21 twenty one 14.036 14.036 0.67 0.67 4 4 28 28 20.150 20.150 0.72 0.72 5 5 36 36 27.343 27.343 0.76 0.76 6 6 43 43 33.758 33.758 0.79 0.79 7 7 51 51 41.189 41.189 0.81 0.81 8 8 58 58 47.758 47.758 0.82 0.82

通过统计分析发现，当小区配置的载频较少时，采用ERL-B表计算其语音业务容量比较准确，因为每小区的信道数有限，每信道的语音业务容量随信道数变化较大；当小区配置的载频较高时，每信道的语音业务容量随信道数变化不大。Through statistical analysis, it is found that when the number of carrier frequencies configured in a cell is small, it is more accurate to use the ERL-B table to calculate its voice service capacity, because the number of channels in each cell is limited, and the voice service capacity of each channel varies greatly with the number of channels; When the carrier frequency configured in the cell is high, the voice service capacity of each channel does not change much with the number of channels.

从上表1可以看出，当载频配置较低时，例如小区配置在三载频以下时，平均每信道的语音业务话务容量的变化在0.38erl/tch——0.67erl/tch，变化较大；而当载频配置较高时，例如小区配置在三载频以上时，平均每信道的语音业务话务容量的变化在0.67erl/tch——0.82erl/tch，变化较小，且在网络配置较高时，运营商也要求网络有一定的过负荷能力，不希望每信道负荷太高，此时可以采用信道数乘以每信道语音业务话务容量计算语音业务话务容量。It can be seen from Table 1 that when the carrier frequency configuration is low, for example, when the cell configuration is below three carrier frequencies, the average voice service traffic capacity per channel changes from 0.38erl/tch to 0.67erl/tch. Larger; and when the carrier frequency configuration is high, for example, when the cell configuration is more than three carrier frequencies, the average voice service traffic capacity per channel changes from 0.67erl/tch to 0.82erl/tch, the change is small, and When the network configuration is relatively high, the operator also requires the network to have a certain overload capacity, and the load per channel is not expected to be too high. At this time, the voice service traffic capacity can be calculated by multiplying the number of channels by the voice service traffic capacity of each channel.

同理，当小区配置的PDCH较少时，采用ERL-C表计算其数据业务话务容量较为准确，当小区配置的数据业务信道较多时，每信道的数据业务话务容量随信道数变化不大，具体统计内容详见下表2：Similarly, when the number of PDCHs configured in a cell is small, it is more accurate to use the ERL-C table to calculate its data traffic capacity. For details, see Table 2 below:

表2不同数据业务信道配置时每信道数据业务话务容量变化情况Table 2 Changes in the traffic capacity of each channel data service when different data service channel configurations are made

信道数 number of channels 平均时延 average delay 包长 package length 话务量 Traffic K值 K value N N D1（单位秒） D1 (in seconds) S(单位秒) S (in seconds) A（ERL） A (ERL) 每信道话务量 Traffic per channel 1 1 0.01 0.01 0.02 0.02 0.33 0.33 0.333 0.333 2 2 0.01 0.01 0.02 0.02 1.15 1.15 0.577 0.577 3 3 0.01 0.01 0.02 0.02 2.06 2.06 0.686 0.686 4 4 0.01 0.01 0.02 0.02 2.99 2.99 0.747 0.747 5 5 0.01 0.01 0.02 0.02 3.94 3.94 0.788 0.788 6 6 0.01 0.01 0.02 0.02 4.9 4.9 0.816 0.816

从上表2可以看出，当载频配置较高时，可以采用信道数乘以每信道数据业务话务容量来计算数据业务话务容量。It can be seen from Table 2 above that when the carrier frequency configuration is relatively high, the data service traffic capacity can be calculated by multiplying the number of channels by the data service traffic capacity of each channel.

因此当网络高配置时，第i个小区实际可用的语音业务和数据业务的总容量V_i可以用下式计算：Therefore, when the network is highly configured, the total capacity V _i of the voice service and data service actually available in the i-th cell can be calculated by the following formula:

V_i=TCH_i×K_V+PDCH_i×K_D V _i =TCH _i ×K _V +PDCH _i ×K _D

其中，TCH_i表示第i个小区的可用TCH数；PDCH_i表示第i个小区的可用PDCH数；K_V表示平均每个TCH信道能够提供的语音业务容量，取值可在0.6~0.8之间，为便于计算，一个本地网可以根据自身的实际情况，统一取一个值；K_V可以用全网的语音业务话务容量比上全网的可用TCH数计算得到，当一个本地网的网络配置没有大的变动的情况下，K_V的值变动不大，可认为是定值；K_D表示平均每个PDCH信道能够提供的数据业务容量，取值可在0.6~0.8之间，为便于计算，一个本地网可以根据自身的实际情况，统一取一个值，K_D可以用全网的数据业务话务容量比上全网的可用PDCH数计算得到，当一个本地网的网络配置没有大的变动的情况下，K_D的值变动不大，可认为是定值。Among them, TCH _i represents the number of available TCHs in the i-th cell; PDCH _i represents the number of available PDCHs in the i-th cell; K _V represents the average voice service capacity that each TCH channel can provide, and the value can be between 0.6 and 0.8 , for the convenience of calculation, a local network can uniformly take a value according to its actual situation; K _V can be calculated by comparing the voice service traffic capacity of the entire network with the available TCH number of the entire network. When the network configuration of a local network In the case of no major changes, the value of K _V does not change much, which can be considered as a fixed value; K _D represents the average data service capacity that each PDCH channel can provide, and the value can be between 0.6 and 0.8. For the convenience of calculation , a local network can uniformly take a value according to its actual situation. K _D can be calculated by using the data traffic capacity of the entire network to compare the number of available PDCHs on the entire network. When the network configuration of a local network does not change significantly In the case of , the value of K _D does not change much and can be considered as a fixed value.

基于上述统计分析，即可获得下述所示的实际网络利用率α₀的计算公式（3）；Based on the above statistical analysis, the calculation formula (3) of the actual network utilization rate α ₀ can be obtained as shown below;

${α α}_{00} = = \frac{{A A}_{V V - - ave ave} + + {A A}_{D D. - - ave ave}}{{TCH TCH}_{S S} \times \times {K K}_{V V} + + {PDCH PDCH}_{S S} \times \times {K K}_{D D.}} - - - - - - ((33)) . .$

在具体实现时，可以获取平均每小区系统忙时语音业务话务量A_V-ave、平均每小区系统忙时数据业务话务量A_D-ave、平均每小区可用语音业务信道TCH_s、平均每小区可用分组数据信道数PDCH_S、平均每个语音数据信道的语音业务容量K_V、平均每个分组数据信道的语音业务容量K_D，其中所述的平均，均为除以全网小区个数的平均，然后，可以采用公式（3）计算获取实际网络利用率α₀。In specific implementation, the average system busy hour voice traffic volume A _V-ave per cell, the average data traffic volume A _D-ave per cell system busy time, the average available voice traffic channel TCH _s per cell, and the average The number of available packet data channels PDCH _S per cell, the average voice service capacity of each voice data channel K _V , and the average voice service capacity of each packet data channel K _D , where the average is divided by the number of cells in the entire network The average of the numbers, and then, formula (3) can be used to calculate and obtain the actual network utilization α ₀ .

进一步地，目前运营商评估无线网络忙闲程度时大多采用实际网络利用率，该实际网络利用率与各地的总话务量、话务密度、话务分布、人口、经济、地理环境等多种因素有关，其数值可以反映该网络不同时间的负荷变化，但不能用来对不同地市间进行横向比较。所谓合理网络利用率，即为在话务需求已知的情况下，网络容量应如何配置最合理。合理的网络容量，应当是恰如其分地满足一段时间内话务需求，即既能满足各小区的话务需求而又没有富余的可拆减载频。由此，可以通过系统忙时语音业务总话务量A_V-total、系统忙时数据业务总话务量A_D-total、全网小区数N、各小区需要配置的语音业务容量和数据业务容量之和C_i来计算获取该合理网络利用率α，具体计算可以采用公式（4）实现：Furthermore, most current operators use the actual network utilization rate when assessing the busyness of the wireless network. The actual network utilization rate is related to the total traffic volume, traffic density, traffic distribution, population, economy, geographical environment, etc. Its value can reflect the load change of the network at different times, but it cannot be used to make horizontal comparisons between different cities. The so-called reasonable network utilization refers to the most reasonable allocation of network capacity when the traffic demand is known. A reasonable network capacity should properly meet the traffic demand for a period of time, that is, it can not only meet the traffic demand of each cell but also have no spare detachable carrier frequency. Thus, the total voice traffic A _V-total when the system is busy, the total data traffic A _D-total when the system is busy, the number of cells in the entire network N, the voice traffic capacity and data traffic that each cell needs to configure The sum of capacities C _i is used to calculate and obtain the reasonable network utilization α. The specific calculation can be realized by formula (4):

$α α = = \frac{{A A}_{V V - - total total} + + {A A}_{D D. - - total total}}{{Σ Σ}_{i i = = 11}^{N N} {C C}_{i i}} - - - - - - ((44)) . .$

再次参见上述表1和表2所给出的统计分析可知，网络高配置时，小区需要配置的语音业务容量和数据业务容量的计算方法可以为：Referring again to the statistical analysis given in Table 1 and Table 2 above, it can be seen that when the network is highly configured, the voice service capacity and data service capacity that the cell needs to be configured can be calculated as follows:

每个小区根据其小区忙时语音业务话务量A_V-i除以系数K_V得到其需要配置的语音业务信道数，每个小区根据其小区忙时数据业务话务量A_D-i除以系数K_D得到其需要配置的分组数据信道数，其中，K_V为平均每个TCH的语音业务容量，K_D为平均每个分组数据信道的数据业务容量。Each cell obtains the number of voice service channels to be configured according to the voice traffic volume A _Vi when the cell is busy, divided by the coefficient K _V , and each cell divides the data traffic volume A _Di by the coefficient K _D when the cell is busy The number of packet data channels to be configured is obtained, wherein K _V is the average voice service capacity of each TCH, and K _D is the average data service capacity of each packet data channel.

然后，将获得的语音业务信道数和分组数据信道数相加后除以基站信道处理模块大小，也即除以一个载频所包含的信道数M，即可获得载频数，再对该载频数向上取整；由于在配置载频时，其步长是M个信道，因此，本发明可以按照现有网络中语音业务优先的原则，把向上取整导致多配的信道数分配给语音业务，而其它信道则可以在语音业务和数据业务之间按比例分配；最后语音业务和数据业务分配的信道数分别乘以系数K_V和系数K_D得到其实际需要配置的话务容量。Then, after adding the obtained voice traffic channel number and packet data channel number and dividing by the base station channel processing module size, that is, dividing by the channel number M contained in a carrier frequency, the carrier frequency number can be obtained, and then the carrier frequency number Round up; because when configuring the carrier frequency, its step size is M channels, therefore, the present invention can allocate the number of channels that are rounded up to the voice service according to the principle of voice service priority in the existing network, The other channels can be allocated proportionally between the voice service and the data service; finally, the number of channels allocated for the voice service and the data service is multiplied by the coefficient K _V and the coefficient K _D respectively to obtain the traffic capacity that actually needs to be configured.

基于上述分析，公式（4）中的C_i具体可以采用公式（5）计算获得：Based on the above analysis, C _i in formula (4) can be calculated by formula (5):

${C C}_{i i} = = {A A}_{V V - - i i} + + {A A}_{D D. - - i i} + + {{ROUNDUP ROUNDUP [[\frac{{A A}_{V V - - i i} / / {K K}_{V V} + + {A A}_{D D. - - i i} / / {K K}_{D D.}}{M m}]] - - \frac{{A A}_{V V - - i i} / / {K K}_{V V} + + {A A}_{D D. - - i i} / / {K K}_{D D.}}{M m}}} \times \times M m \times \times {K K}_{V V} - - - - - - ((55))$

其中，M表示一个载频中包含的信道数，ROUNDUP为向上取整函数。举例来说，在GSM系统中，一个载频中包含8条信道。Among them, M represents the number of channels contained in a carrier frequency, and ROUNDUP is an upward rounding function. For example, in the GSM system, one carrier frequency contains 8 channels.

K_V表示平均每个TCH信道能够提供的语音业务容量，取值可在0.6~0.8之间，为便于计算，一个本地网可以根据自身的实际情况，统一取一个值；K_V可以用语音业务话务容量比上全网可用TCH数计算得到，当一个本地网的网络配置没有大的变动的情况下，K_v的值变动不大，可认为是定值；K_D表示平均每个PDCH能够提供的数据业务容量，取值可在0.6~0.8之间，为便于计算，一个本地网可以根据自身的实际情况，统一取一个值；K_D可以用数据业务话务容量比上全网可用PDCH数计算得到，当一个本地网的网络配置没有大的变动的情况下，K_D的值变动不大，可认为是定值。K _V represents the average voice service capacity that each TCH channel can _provide . The traffic capacity is calculated from the number of available TCHs in the entire network. When the network configuration of a local network does not change significantly, the value of K _v does not change much, which can be considered as a fixed value; K _D means that each PDCH can The data service capacity provided can be between 0.6 and 0.8. For the convenience of calculation, a local network can take a uniform value according to its actual situation; _KD can use the data service capacity to compare with the PDCH available on the entire network. According to the calculation, when the network configuration of a local network does not change greatly, the value of K _D does not change much, which can be considered as a fixed value.

需要说明的是，由于现在大部分网络都开通了半速率，且部分网络中的半速率话务量占比较大，为了更加准确地反映网络资源的利用情况，在计算系统忙时语音业务总话务量时可以对半速率话务量折半进行考虑，即系统忙时语音业务话务量=系统忙时全速率业务话务量+系统忙时半速率业务话务量/2。It should be noted that, since half-rate traffic is enabled on most networks now, and half-rate traffic accounts for a large proportion in some networks, in order to more accurately reflect the utilization of network resources, the total voice traffic volume when the computing system is busy The half-rate traffic can be halved when the system is busy, that is, the voice service traffic when the system is busy = the full-rate business traffic when the system is busy + the half-rate business traffic/2 when the system is busy.

在具体实现时，发明人进一步发现，将上述公式（5）带入上述公式（4）中计算合理网络利用率时，需要进行N个小区的求和处理，计算过程较为繁琐。为了降低计算量，发明人对将上述公式（5）带入公式（4）后的计算公式进行了进一步的改进，采用下述公式（6）计算获取合理网络利用率α：In actual implementation, the inventor further found that when the above formula (5) is incorporated into the above formula (4) to calculate the reasonable network utilization rate, the summation processing of N cells is required, and the calculation process is relatively cumbersome. In order to reduce the amount of calculation, the inventor further improved the calculation formula after incorporating the above formula (5) into formula (4), and used the following formula (6) to calculate and obtain a reasonable network utilization rate α:

$α α = = \frac{{A A}_{V V - - ave ave} + + {A A}_{D D. - - ave ave}}{{A A}_{V V - - ave ave} \times \times {β β}_{V V} + + {A A}_{D D. - - ave ave} \times \times {β β}_{D D.} + + M m / / 22 \times \times {K K}_{V V}} - - - - - - ((66))$

其中，A_V-ave为平均每小区系统忙时语音业务话务量，A_D-ave为平均每小区系统忙时数据业务话务量，β_V为语音业务小区忙时不均衡系数，β_D为数据业务小区忙时不均衡系数，M表示一个载频中包含的信道数，K_V为平均每个语音业务信道的语音业务容量。Among them, A _V-ave is the average traffic volume of the voice service in each cell when the system is busy, A _D-ave is the average traffic volume of the data service in each cell when the system is busy, β _V is the unbalance coefficient of the voice service cell in busy hours, β _D Is the unbalance coefficient of the data service cell during busy hours, M indicates the number of channels contained in one carrier frequency, and K _V is the average voice service capacity of each voice service channel.

具体来说，将所述A_V-total除以所述N，即可得到所述A_V-ave；将所述A_D-total除以所述N，即可得到所述A_D-ave；将所述语音业务话务容量除以全网可用语音业务信道数，即可得到所述K_V；将小区忙时语音业务话务量除以A_V-total，即可得到所述β_V；将小区忙时数据业务话务量除以A_D-total，即可得到所述β_D。Specifically, divide the A _V-total by the N to obtain the A _V-ave ; divide the A _D-total by the N to obtain the A _D-ave ; The K _V can be obtained by dividing the voice service traffic capacity by the number of available voice service channels in the whole network; the β _V can be obtained by dividing the voice service traffic volume by A _V-total when the cell is busy; The β _D can be obtained by dividing the traffic volume of the data service when the cell is busy by A _D-total .

在获取了合理网络利用率之后，就可以利用前述公式（3）计算获取的实际网络利用率与公式（6）计算获取的合理网络利用率的差值获得无线网络超载率Δα=α₀-α）来进行不同地市、省份之间的横向比较，并且可以计算出来当前网络需要增配的无线网络容量。After obtaining the reasonable network utilization rate, the difference between the actual network utilization rate calculated by the aforementioned formula (3) and the reasonable network utilization rate calculated by the formula (6) can be used to obtain the wireless network overload rate Δα=α ₀ -α ) to conduct horizontal comparisons between different cities and provinces, and can calculate the wireless network capacity that needs to be added to the current network.

Δα是衡量网络忙闲的指标，当Δα为负时，表示目前的网络比较闲，话务尚有提升空间，可以通过话务量营销等手段来推动话务量增长，从而提升现网的利用率。当Δα为零时，表示当前的话务量和实际的网络配置恰好匹配，是网络资源利用最充分的状态。当Δα为正时，表示目前的网络比较繁忙，无线网络容量配置不足，需要通过扩容来满足当前的话务需求。Δα is an index to measure the busyness of the network. When Δα is negative, it means that the current network is relatively idle, and there is still room for improvement in traffic. Traffic volume marketing and other means can be used to promote traffic growth, thereby improving the utilization of the existing network Rate. When Δα is zero, it means that the current traffic volume and the actual network configuration just match, which is the most fully utilized state of network resources. When Δα is positive, it means that the current network is relatively busy, and the wireless network capacity configuration is insufficient, and capacity expansion is needed to meet the current traffic demand.

从前面超载率定义可知，当超载率Δα为零时，无线网络的容量刚好满足业务需求，既不需要扩容，也没有可拆减的载频，是无线资源利用最充分的状态。因此，从资源利用角度，本实施例定义了超载率为零时的网络利用率为目标网络利用率。From the definition of the overload rate above, we can see that when the overload rate Δα is zero, the capacity of the wireless network just meets the business needs, and there is no need for capacity expansion, and there is no removable carrier frequency, which is the state where the wireless resources are fully utilized. Therefore, from the perspective of resource utilization, this embodiment defines the network utilization rate as the target network utilization rate when the overload rate is zero.

根据综合的实际网络利用率和合理网络利用率的近似公式，即公式（3）和公式（6），令这两个公式相等，并设定数据业务话务量与语音业务话务量的比例DVR，则可以推导出目标网络利用率的近似公式如下：According to the approximate formula of comprehensive actual network utilization rate and reasonable network utilization rate, that is, formula (3) and formula (6), make these two formulas equal, and set the ratio of data service traffic to voice service traffic DVR, the approximate formula for the target network utilization can be deduced as follows:

如果K_V取值与K_D取值相同，则上式可简化为下式：If the value of K _V is the same as that of K _D , the above formula can be simplified to the following formula:

${α α}_{11} = = \frac{((11 + + DVR DVR)) \times \times (({Tch Tch}_{S S} - - M m / / 22 + + {PDCH PDCH}_{S S}))}{(({Tch Tch}_{S S} + + {PDCH PDCH}_{S S})) \times \times (({β β}_{V V} + + DVR DVR \times \times {β β}_{D D.}))} - - - - - - ((77))$

在具体实现时，采用公式（1）或者公式（7）获取目标网络利用率之前，可以进行如下预处理过程：In actual implementation, before using formula (1) or formula (7) to obtain the target network utilization, the following preprocessing process can be performed:

将全网可用语音业务信道数除以所述全网小区数，得到所述TCH_s；Divide the number of voice service channels available in the entire network by the number of cells in the entire network to obtain the TCH _s ;

将全网可用分组数据信道数除以所述全网小区数，得到所述PDCH_S；Divide the number of available packet data channels in the entire network by the number of cells in the entire network to obtain the PDCH _S ;

将语音业务话务容量除以所述全网可用语音业务信道数，得到所述K_V；Dividing the voice service traffic capacity by the number of voice service channels available in the entire network to obtain the _KV ;

将数据业务话务容量除以所述全网可用数据业务信道数，得到所述K_D；将小区忙时语音业务话务量除以系统忙时语音业务总话务量，得到所述β_V；Divide the data service traffic capacity by the number of available data service channels in the entire network to obtain the _KD ; divide the voice service traffic volume when the cell is busy by the total voice service traffic volume when the system is busy to obtain the β _V ;

将小区忙时数据业务话务量除以系统忙时数据业务话务量，得到所述β_D。The β _D is obtained by dividing the traffic volume of the data service when the cell is busy by the traffic volume of the data service when the system is busy.

因此，本实施例，针对高配置网络中同时存在语音业务和数据业务的情况，通过获取的DVR、TCHs、PDCH_S、K_V、K_D、β_V以及β_D，可以计算获得系统的目标网络利用率，且该计算过程是在对语音业务话务容量和数据业务话务容量的统计分析的基础上进行的，其计算简单，且结果准确，能够较为客观地反映系统所需的目标网络资源配置。Therefore, in this embodiment, aiming at the situation where there are both voice services and data services in a high-configuration network, the target network of the system can be calculated and obtained through the obtained DVR, TCHs, PDCH _S , K _V , K _D , β _V and β _D Utilization, and the calculation process is based on the statistical analysis of the voice service traffic capacity and data service traffic capacity, the calculation is simple and the result is accurate, which can objectively reflect the target network resources required by the system configuration.

在采用上述实施例获取目标网络利用率之后，还可以采用下述公式（2）获取无线网络目标差Δα₀：After obtaining the target network utilization ratio by using the above embodiment, the following formula (2) may also be used to obtain the wireless network target difference Δα ₀ :

Δα₀=α₀-α₁ （2）Δα ₀ =α ₀ -α ₁ (2)

其中，α₀为实际网络利用率，α₀采用公式（3）计算获得。Among them, α ₀ is the actual network utilization, and α ₀ is calculated by formula (3).

Δα₀是衡量网络忙闲的指标。当Δα₀>0时，表示当前的话务量大于网络能够承载的最佳话务量，网络偏繁忙；当Δα₀<0，表示当前的话务量小于网络能够承载的最佳话务量，网络偏闲置，当前的网络尚有一定的话务量提升空间；当Δα₀＝0，当前的话务量和实际的网络配置恰好匹配，是网络资源利用最充分的状态。Δα ₀ is an index to measure the busyness of the network. When Δα ₀ >0, it means that the current traffic is greater than the optimal traffic that the network can carry, and the network is busy; when Δα ₀ <0, it means that the current traffic is less than the optimal traffic that the network can carry , the network is relatively idle, and the current network still has a certain room for traffic increase; when Δα ₀ =0, the current traffic and the actual network configuration just match, which is the most fully utilized state of network resources.

该无线网络目标差Δα₀可以在网络规划和调整时具有如下功能：The wireless network target difference Δα ₀ can have the following functions during network planning and adjustment:

当Δα₀<0时，话务尚有提升空间，可以通过话务量营销等手段来推动话务量增长，从而提升现网的利用率。系统忙时话务提升空间的计算公式如下所示：When Δα ₀ <0, there is still room for traffic improvement, and traffic volume marketing and other means can be used to promote traffic growth, thereby increasing the utilization rate of the existing network. The formula for calculating the traffic boost space when the system is busy is as follows:

系统忙时话务提升空间=现网无线容量×目标网络利用率-现网系统忙时话务量。Traffic improvement space when the system is busy = wireless capacity of the existing network × target network utilization rate - traffic volume when the system is busy.

当Δα₀＝0时，表示当前的话务量和实际的网络配置恰好匹配，是网络资源利用最充分的状态。When Δα ₀ =0, it means that the current traffic volume exactly matches the actual network configuration, which is the state where network resources are fully utilized.

当Δα₀>0时，表示目前的网络比较繁忙，无线网络容量配置不足，需要通过扩容来满足当前的话务需求，需要增配的无线容量的计算公式如下所示：When Δα ₀ >0, it means that the current network is relatively busy and the wireless network capacity configuration is insufficient, and capacity expansion is required to meet the current traffic demand. The calculation formula for the additional wireless capacity is as follows:

需要增配的无线容量=现网系统忙时话务量/合理网络利用率-现网无线容量。The wireless capacity that needs to be added = the traffic volume of the existing network system during busy hours / the reasonable network utilization rate - the wireless capacity of the existing network.

需要注意的是，现网系统忙时话务量指的是语音业务话务量与数据业务话务量之和，现网无线容量指的是语音业务容量与数据业务容量之和。It should be noted that the traffic volume of the existing network system during busy hours refers to the sum of voice service traffic and data service traffic, and the existing network wireless capacity refers to the sum of voice service capacity and data service capacity.

另外，对于Δα₀>0的省份，可以以合理网络利用率作为其网络利用率的达标值；In addition, for provinces where Δα ₀ >0, reasonable network utilization can be used as the standard value of network utilization;

对于Δα₀在-5%~0%之间的省份，可以直接以目标网络利用率作为网络利用率的达标值；For provinces where Δα ₀ is between -5% and 0%, the target network utilization rate can be directly used as the standard value of the network utilization rate;

对于Δα₀在-10%～-5%之间的省份，网络利用率的达标值可以为实际网络利用率+|Δα₀|/2For provinces where Δα ₀ is between -10% and -5%, the up-to-standard value of network utilization can be the actual network utilization +|Δα ₀ |/2

对于Δα₀在-25～-10%之间的省份，网络利用率的达标值为实际网络利用率+|Δα₀|/3。For provinces where Δα ₀ is between -25 and -10%, the standard value of network utilization is the actual network utilization +|Δα ₀ |/3.
