4、he basic principles of wireless network quality is C/I ( CIR ). C/I improvement can reduce the bit error rate, frame loss rate, improve the quality of speech, MOS perception, is the underlying index of wireless network optimization; while others such as the drop rate, the success rate of switching,

5、wireless access, KPI index is high in the performance of the C/I reaction. Therefore, the focus of network optimization is the optimization of C/I, this deviation from the target, the blind pursuit of high KPI is unrealistic.1.2提高網(wǎng)絡(luò)質(zhì)量評(píng)價(jià)的關(guān)鍵Key 1.2 to improve network quality evaluation隨著網(wǎng)絡(luò)發(fā)展日益復(fù)雜，各種干擾也

6、越來越多，在功率配置問題上絕大多數(shù)網(wǎng)優(yōu)人員解 決干擾的手段是提高功率來抗干擾，高電平高干擾，這樣會(huì)導(dǎo)致高電平質(zhì)差比率升高，整網(wǎng) 質(zhì)量不高，且由于存在網(wǎng)絡(luò)質(zhì)量的不平衡分布，易使終端用戶產(chǎn)生感知上的差異化，引發(fā)投 訴上升及滿意度下降。在與競(jìng)爭(zhēng)對(duì)手的比拼中處于優(yōu)勢(shì)，和在網(wǎng)內(nèi)盡量保持各處同性是同樣 重要的。網(wǎng)絡(luò)優(yōu)化是一門平衡的藝術(shù)，平衡性是提高網(wǎng)絡(luò)質(zhì)量評(píng)價(jià)的關(guān)鍵。With the development of network is becoming more and more complex, various interference is also increasing, the power all

The advantage in the competition and the competition in the network, and try to keep all gay is equally important. Network optimization is an art of balance, the balance is the key to impro

9、ve the network quality evaluation.舉例：路測(cè)優(yōu)化。由于路測(cè)考核指標(biāo)越來越成為各運(yùn)營(yíng)商關(guān)注的重點(diǎn)，因此在優(yōu)化上也 就自然而然地會(huì)傾注更多的資源，對(duì)道路覆蓋小區(qū)頻率使用進(jìn)行傾斜、大功率保證C/I，提 升各類道路測(cè)試指標(biāo)。乍一看這樣的做法效果不錯(cuò)，可細(xì)想一下問題就來了，路測(cè)道路占整 體覆蓋面積不足10%，用戶不及20%，而這些區(qū)域C的強(qiáng)化勢(shì)必導(dǎo)致90%區(qū)域和80%用戶 的干擾上升，將顯著降低原本就覆蓋受限區(qū)域的C/I，影響客戶感知，從實(shí)際投訴比率上也 可以看到，室內(nèi)投訴比率占絕大多數(shù)。因此，一視同仁(道路和室內(nèi))的總體網(wǎng)絡(luò)優(yōu)化策略 能更好地改善用戶感知，提高滿意度，

10、這是平衡的觀點(diǎn)。For example: the road test optimization. Because the road test evaluation has increasingly become the focus of the operators, so in the optimization will come very naturally to pour more resources, covering area frequency using tilt, on the road of high power C/I, promote all kinds of road t

11、est index. At first glance this practice effect is good, can consider the issue came, road test road total covering area of less than 10%, the user less than 20%, while strengthening the regional C will lead to rising interference of the 90% region and the 80% user, will significantly reduce the ori

12、ginal coverage is limited to regional C/I, impact of customer perception, from the actual complaints the ratio can be seen, the majority of indoor complaint ratio. Therefore, make no exception ( road and indoor ) of the overall network optimization strategies can better improve user perception, incr

13、ease satisfaction, this is a balanced view.1.3 C/I和功率的關(guān)系Relationship between 1.3 C/I and power改善C/I的方法有兩個(gè)：提高C或降低I。提高用戶感知還可以運(yùn)用一些新功能，改善 相同C/I情況下的MOS表現(xiàn)，如AMR、跳頻等。Method for improving C/I has two: increasing C or reducing I. Improve the user perceived can also use some new functions, improve the MOS perf

14、ormance under the condition of the same C/I, such as AMR, frequency hopping.提高C的主要方法是提升功率、調(diào)整覆蓋、優(yōu)化鄰區(qū)配置；(1 ) the main method of improving C is to enhance the power, adjust to cover adjacent area configuration, optimization;降低I的主要方法是降低功率、調(diào)整覆蓋、優(yōu)化頻率配置、控制外部干擾等。(2 ) reduction of I is the main method of red

15、ucing the power, adjust the coverage, frequency allocation, optimization control of external interference.功率調(diào)整最為糾結(jié)，增加功率即增加了 C和I，增加單小區(qū)抗干擾能力的同時(shí)增加了全 局干擾；減少功率降低I的同時(shí)也降低了 C。The struggle for power adjustment, increase power is increased by C and I, and increase the anti-interference ability of single cell

16、increased global interference; reduce the power reduction of I also reduces the C.I由白噪聲、外部干擾(各類干擾設(shè)備)和內(nèi)部干擾(頻率干擾和交調(diào)干擾)構(gòu)成，可 見在調(diào)整功率時(shí)主要影響的是內(nèi)部干擾。下面模擬了一條C/I VS Lev的曲線做個(gè)簡(jiǎn)單示意 圖，如圖1所示：I consists of white noise, the external disturbance ( all kinds of jamming equipment ) and internal interference ( frequency i

The simulation of a C/I VS Lev curves do a simple diagram, as shown in figure 1:其中，橫軸為全網(wǎng)的平均接收電平；縱軸為全網(wǎng)的平均C/I。圖1主要分為3個(gè)區(qū)、1 個(gè)點(diǎn)，具體描述如下：Among them, the horizontal axis is the average received power networ

Figure 1 is divided into 3 zones, 1 points, is described as follows:A區(qū)：此處屬于低功率區(qū)域，干擾主要由底噪、外部干擾強(qiáng)度決定，因此隨著電平功率 的提升，C/I上升很快。A area: here belongs to the low power region, determines the interference is mainly composed of background noise, external disturban

20、強(qiáng)度已經(jīng)無法進(jìn)一步提升，全網(wǎng)電平 的提升是部分小區(qū)的提升貢獻(xiàn)的，對(duì)一個(gè)小區(qū)覆蓋而言，其主控面積遠(yuǎn)小于干擾面積，因此 在不能全網(wǎng)提升功率的情況下，C的增加速度會(huì)慢于I的增加速度，導(dǎo)致C/I的下降。而隨 著平均電平的增加，功率受限區(qū)域也不斷增加，I的增加亦越來越快，C/I呈現(xiàn)加速下滑。 目前大部分網(wǎng)絡(luò)運(yùn)行在C區(qū)（以暴制暴的結(jié)果）。C area: level of intensity in the deep web coverage or coverage area has been unable to further enhance the level of ascension, is part

21、of the contribution to the upgrading of the District, covering a area, the main area is much smaller than the interference area, so not all network upgrade in power, the increase of C speed will be slower than I growth rate, lead to the decrease of C/I.

27、nversion從上文可知，大部分網(wǎng)絡(luò)運(yùn)行在C區(qū)，不是網(wǎng)絡(luò)的最佳運(yùn)行區(qū)域，將網(wǎng)絡(luò)置于P點(diǎn)運(yùn) 行才能獲得最佳質(zhì)量。那么如何確定P點(diǎn)呢？首先網(wǎng)絡(luò)功率水平的調(diào)整主要依靠最大功率 水平設(shè)置(會(huì)影響覆蓋、話務(wù)分布等，在下面介紹中不采用)和功控參數(shù)設(shè)置(功控范圍、 功控區(qū)間)實(shí)現(xiàn)。實(shí)現(xiàn)網(wǎng)絡(luò)P點(diǎn)運(yùn)行有以下難度：From the above shows, most of the network operation in the C District, the best operation area is not the network, the network in the P operation can o

The first network power level adjustment mainly rely on setting a maximum power level ( will affect the coverage, traffic distribution, do not use in the following introduction ) and power control parameters ( power control range, power contro

Realization of network points operation has the following difficulty: 從現(xiàn)有的GSM網(wǎng)絡(luò)統(tǒng)計(jì)中，缺乏對(duì)C/I的統(tǒng)計(jì)，無法很好地評(píng)價(jià)調(diào)整效果；(1 ) from the GSM network statistics available, the lack of statistics on the C/I, are unable to evaluate the adjustment effect;功率水平的統(tǒng)計(jì)是平均值，在設(shè)置上是區(qū)間值，也較難實(shí)現(xiàn)參數(shù)設(shè)置和網(wǎng)絡(luò)響應(yīng) 的吻

30、合，橫坐標(biāo)位置較難確定。(2 ) the level of statistical power is the mean value, in the set is an interval, it is more difficult to achieve consistent parameter setting and the response of the network, it is difficult to determine the horizontal position.需要想一個(gè)變通的方法將這兩個(gè)指標(biāo)轉(zhuǎn)化為易獲取、易度量且相關(guān)性極強(qiáng)的指標(biāo)。在GSM網(wǎng)絡(luò)中，受C/I影響最大最直接的指標(biāo)是

31、quality, quality的統(tǒng)計(jì)也非常容易獲取，這 就是變色龍算法第一步。將上面的C/I VS Lev的圖轉(zhuǎn)換為目標(biāo)quality VS實(shí)際quality的圖， 如圖2所示：Need a flexible method to convert the two indexes for easy access, easy and extremely strong correlation index. In GSM network, the largest and most directly affected by C/I index is quality, quality statistics

32、 is also very easy to get, this is the first step of chameleon algorithm. Convert C/I VS above Lev patterns for quality VS quality map, as shown in figure 2:其中，橫軸為目標(biāo)質(zhì)量(自左向右，由好到壞)；豎軸為實(shí)際質(zhì)量(自下而上，由好到 壞)。Among them, the horizontal axis is the target quality ( from left to right, from good to bad ); the v

33、ertical axis for the actual quality ( from bottom to top, from good to bad ).A區(qū)：當(dāng)目標(biāo)質(zhì)量要求較低時(shí)，電平配置較低，C/I比較差，仍有功率及質(zhì)量提升空間。A area: when the target quality requirement is low, level configuration is low, C/I is relatively poor, still have the power and enhance the quality of space.C區(qū)：當(dāng)目標(biāo)質(zhì)量要求較高時(shí)，電平配置升高，產(chǎn)生的干

34、擾增大，導(dǎo)致C/I變差，實(shí)際 質(zhì)量差于目標(biāo)值。C area: when the target of higher quality requirements, high level configuration, increasing interference, leading to C/I variation, the actual quality is poor in the target value.P線：不同網(wǎng)絡(luò)特性的最佳點(diǎn)P，在此處能達(dá)到實(shí)際質(zhì)量最佳。在圖2中表現(xiàn)為目標(biāo)質(zhì) 量和實(shí)現(xiàn)質(zhì)量一致，即斜率為1，匯聚成P線。Line P: the best point of different n

35、etwork characteristics of P, here to achieve practical best quality. As shown in Figure 2 for the target quality and achieve consistent quality, namely, a slope of 1, converge into P line.通過這樣的圖形轉(zhuǎn)換，就把問題簡(jiǎn)化到了以質(zhì)量為目標(biāo)的優(yōu)化過程，而質(zhì)量統(tǒng)計(jì)非常方 便，便于實(shí)現(xiàn)調(diào)整和評(píng)估的工作。Conversion through this graph, the problem is reduced to t

36、he optimization process to quality as the goal, and the quality of statistics is very convenient, easy adjustment and evaluation work.2.2逼近P點(diǎn)2.2 approximation of P完成圖形轉(zhuǎn)化后，仍需要找到P點(diǎn)的位置，通過實(shí)踐和研究總結(jié)出了一套算法，由于 其能敏銳捕捉周圍環(huán)境變化，自適應(yīng)調(diào)整無線參數(shù)，將網(wǎng)絡(luò)置于最佳點(diǎn)P運(yùn)行，降低干擾， 提高網(wǎng)絡(luò)質(zhì)量，因此取名“變色龍”。Complete the graphics transformation, sti

38、prove the quality of network, so the name chameleon .變色龍算法的第二步是尋找P點(diǎn)，這里采用無限逼近的方法，說明如下：The chameleon algorithm for the second step is to look for points, here using method of infinite approximation, as described below:假設(shè)網(wǎng)絡(luò)最初目標(biāo)質(zhì)量設(shè)置是q1，網(wǎng)絡(luò)反饋的實(shí)際質(zhì)量是q2；接著以q2為目標(biāo)質(zhì)量， 網(wǎng)絡(luò)會(huì)反饋出q3；再以q3得出q4由于P線的斜率為1，因此網(wǎng)絡(luò)的反饋會(huì)逐步收斂， 這樣

39、網(wǎng)絡(luò)運(yùn)行點(diǎn)就無限逼近P線，達(dá)到網(wǎng)絡(luò)最佳質(zhì)量。在此過程中排除了人為的對(duì)參數(shù)設(shè) 定的猜測(cè)，而全由網(wǎng)絡(luò)反饋決定參數(shù)設(shè)置，形成了自適應(yīng)過程，也就是說網(wǎng)絡(luò)需要多少能量， 就會(huì)去要求獲取，通過這一過程大大提高了無線參數(shù)設(shè)置的準(zhǔn)確性，如圖3所示：The initial goal hypothesis network quality setting is Q1, the actual quality of feedback network is Q2; and then takes Q2 as the goal of quality, the network will feedback to the Q4 Q

40、3 Q3Dueto the slope of the P curve was 1, so the network feedback will gradually converge, so that the network operating point of infinite approximation of the P line, achieve the best network quality. In the process of eliminating the human to set the parameters of speculation, but by the network f

42、 algorithm.GSM廠家功控算法的理想目標(biāo)是在質(zhì)量允許的條件下功率盡可能低，這就需要去尋找 這個(gè)質(zhì)量和電平的穩(wěn)定區(qū)域。大多數(shù)優(yōu)化人員會(huì)根據(jù)經(jīng)驗(yàn)定一套區(qū)間參數(shù)放到現(xiàn)網(wǎng)上運(yùn)行， 細(xì)致點(diǎn)的可能會(huì)考慮分場(chǎng)景設(shè)置功控參數(shù)。然而，什么樣的設(shè)置才能真正滿足適合場(chǎng)景、規(guī) 劃、話務(wù)、外部干擾等多種變量引起的功率需求變動(dòng)呢？Ideal power control algorithm for GSM manufacturers in quality under the conditions allowed power as low as possible, the stable region which n

However, what settings can really meet the power demand for the scene, plannin

44、g, traffic, external interference and other variables caused changes?變色龍算法的第三步是將靶心圖中的質(zhì)量區(qū)間和電平區(qū)間盡量重疊，使功率趨于穩(wěn)定， 并且盡可能地降低發(fā)射功率，減少整網(wǎng)的干擾。這樣做能使電平和質(zhì)量做合理轉(zhuǎn)換，因?yàn)樵?GSM網(wǎng)內(nèi)質(zhì)量的參數(shù)設(shè)定為07,電平設(shè)定為-110dBm-47dBm，顯然電平設(shè)置更為精細(xì)， 質(zhì)量區(qū)間和電平區(qū)間靠近的好處是不會(huì)由于兩者的偏離導(dǎo)致功控方向的不確定。The third step is the chameleon algorithm will target chart of qualit

45、y interval and level interval to overlap, so that the power tends to be stable, and as far as possible to reduce the transmission power to reduce interference, the whole network. It can make the level and quality of reasonable conversion, because the parameters of quality in GSM network is set to 0

46、7, the level set is -110dBm -47dBm, apparently level setting more fine, close to the quality and level of interval interval is not good because of the uncertainty of the deviation caused power control direction.通過采集話務(wù)統(tǒng)計(jì)數(shù)據(jù)收集測(cè)量報(bào)告，進(jìn)行電平質(zhì)量二維整理，完成環(huán)境數(shù)據(jù)的收集。 某小區(qū)的情況如表1所示：Collect measurement reports by collect

A small case such as shown in table 1:其中，填色部分的數(shù)字表示對(duì)應(yīng)電平等級(jí)以下、下一級(jí)電平等級(jí)以上的對(duì)應(yīng)上行質(zhì)量等 級(jí)的采樣點(diǎn)比例，所有填色格子相加為100。通過質(zhì)量和電平的綜合分析，能很方便地確定 穩(wěn)定區(qū)域，實(shí)現(xiàn)質(zhì)量和電平的等效轉(zhuǎn)換。Among them, coloring number corresponding level under the l

Through a comprehensive analysis of the quality and level, can easily determine the stability region, achieve equivalent quality and level conversion.由表1可見，電平強(qiáng)的時(shí)候，質(zhì)差占比較低；而電平弱的時(shí)

49、候較高。功控的目的是保證 質(zhì)量的情況下盡可能降低發(fā)射功率，也就是說合理設(shè)置功控電平區(qū)間，不宜設(shè)得過低引起質(zhì) 差，不宜設(shè)得過高產(chǎn)生干擾。反饋的結(jié)果能進(jìn)一步修正設(shè)置的精確度。Can be seen from table 1, when the level of strong, poor quality of relativelylow; and when the weak high level.

50、wer, that is to say a reasonable set of power control level interval, should not be set too low due to poor quality, should not be too high to produce interference. The results can be further feedback correction setting accuracy.通過測(cè)量報(bào)告能清晰地了解干擾分布狀況，進(jìn)行精確功率分配，可以說有多少小區(qū)就有 多少場(chǎng)景，實(shí)現(xiàn)因地制宜。更精細(xì)的做法是可以根據(jù)不同時(shí)段進(jìn)行功控參
