建议：将 XA109-1的BCCH由78改为87。 3XAS283-0过覆盖：问题描述：在亚建高尔夫院内的测试中，手机首先占用XA928-1，通话结束后，重选到全向小区XAS283-0，而后占用跳频信道进行通话，此时电平70dBm，TA=20，由于覆盖过远，被同跳频组的小区干扰，话质较差，并且在此形成孤岛，没有合适的邻小区可以切出，以致严重影响了该区域的通话质量。下图是XAS283-0地理位置：XAS283-0的小区性能如下：cellNameTimeDateTCH掉话率不含切换切换成功率TCH分配执行失败率uplinkleveldownlinkleveluplinkqualitydownlinkqualityXA109_110:0023-May-052.36%92.02%2.00%-73.36-78.220.551.75XA109_110:0024-May-051.75%89.98%1.83%-72.41-78.090.561.40XA109_110:0025-May-051.24%69.67%1.88%-72.90-78.250.651.65XA109_119:0023-May-051.58%90.34%2.70%-75.85-80.200.832.37XA109_119:0024-May-050.71%90.58%3.11%-73.48-78.600.632.02XA109_119:0025-May-050.40%89.67%1.79%-79.84-81.410.751.67XA109_120:0023-May-050.57%86.22%2.70%-74.00-78.170.742.39XA109_120:0024-May-051.57%82.00%2.59%-75.35-79.930.782.33XA109_120:0025-May-051.65%92.30%1.43%-79.84-80.651.001.96XA602_110:0023-May-050.22%91.49%0.45%-72.87-74.880.661.07XA602_110:0024-May-050.59%96.06%0.30%-73.58-75.430.760.91XA602_110:0025-May-050.48%95.34%1.33%-73.30-75.130.721.03XA602_119:0023-May-051.36%91.36%1.16%-74.91-76.400.960.86XA602_119:0024-May-050.25%94.57%0.90%-72.69-74.590.740.93XA602_119:0025-May-051.13%94.07%0.75%-74.35-75.890.700.98XA602_120:0023-May-050.83%94.63%0.75%-72.74-74.530.750.87XA602_120:0024-May-050.82%93.66%0.68%-73.44-74.830.840.92XA602_120:0025-May-050.68%90.26%0.43%-76.16-77.650.821.07XA619_110:0023-May-050.67%97.15%0.67%-81.82-79.130.721.33XA619_110:0024-May-050.00%93.67%0.62%-83.51-81.000.821.73XA619_110:0025-May-050.20%74.62%0.41%-87.25-84.710.941.78XA619_119:0023-May-050.52%94.35%0.00%-83.33-80.680.751.29XA619_119:0024-May-052.49%92.22%0.50%-81.58-80.480.691.13XA619_119:0025-May-050.41%97.01%0.41%-82.47-80.160.711.15XA619_120:0023-May-050.76%92.71%1.13%-82.91-80.190.711.61XA619_120:0024-May-050.68%94.50%0.00%-84.11-81.650.841.89XA619_120:0025-May-051.39%88.89%1.03%-86.02-83.500.911.43XA913_010:0023-May-051.56%91.89%1.54%-85.91-76.071.781.16XA913_010:0024-May-051.51%94.53%1.51%-84.53-75.311.651.23XA913_010:0025-May-051.04%92.30%1.27%-83.63-74.091.571.08XA913_019:0023-May-051.27%93.50%2.01%-82.71-73.511.251.04XA913_019:0024-May-051.30%93.62%0.90%-82.52-72.671.270.76XA913_019:0025-May-051.31%93.02%1.52%-85.38-76.101.340.88XA913_020:0023-May-051.03%88.27%1.14%-85.23-75.391.431.02XA913_020:0024-May-051.23%82.96%2.02%-85.08-75.031.761.33XA913_020:0025-May-051.43%83.87%1.33%-85.80-75.641.801.01XAS283_010:0023-May-051.12%94.78%2.19%-83.13-78.231.010.88XAS283_010:0024-May-052.01%93.64%2.00%-83.62-77.991.001.11XAS283_010:0025-May-050.65%83.70%3.57%-84.21-78.051.280.98XAS283_019:0023-May-051.46%90.15%3.67%-82.59-77.460.941.03XAS283_019:0024-May-050.99%89.46%2.90%-83.38-77.441.150.99XAS283_019:0025-May-052.53%91.99%3.96%-84.21-78.101.461.28XAS283_020:0023-May-051.53%85.73%4.56%-84.76-79.091.251.02XAS283_020:0024-May-052.98%89.37%3.30%-83.45-76.971.420.92XAS283_020:0025-May-052.08%89.74%2.20%-85.73-79.551.270.96调整建议：降低XAS283-0站高，或者，将XAS283-0进行O改S并且增加俯仰角缩小覆盖。4.XA619-1过覆盖：问题描述：图示位置亚建高尔夫院内，占用XA928-1信号，通话质量较差，话质7级。问题分析：测试中，手机占用XA928-1非跳频信道，TCH82，由于亚建高尔夫院内地形起伏较大，信号很不稳定，电平在78dBm左右波动，话质7级，从现象看同频，邻频的干扰的可能性较大，观察邻小区电平，发现邻频的XA619-1（BCCH83）在此处信号较强，电平在75dBm左右。XA619-1的地理位置图如下：XA619-1的小区性能如下：cellNameTimeDateTCH掉话率不含切换切换成功率TCH分配执行失败率uplinkleveldownlinkleveluplinkqualitydownlinkqualityXA109_110:0023-May-052.36%92.02%2.00%-73.36-78.220.551.75XA109_110:0024-May-051.75%89.98%1.83%-72.41-78.090.561.40XA109_110:0025-May-051.24%69.67%1.88%-72.90-78.250.651.65XA109_119:0023-May-051.58%90.34%2.70%-75.85-80.200.832.37XA109_119:0024-May-050.71%90.58%3.11%-73.48-78.600.632.02XA109_119:0025-May-050.40%89.67%1.79%-79.84-81.410.751.67XA109_120:0023-May-050.57%86.22%2.70%-74.00-78.170.742.39XA109_120:0024-May-051.57%82.00%2.59%-75.35-79.930.782.33XA109_120:0025-May-051.65%92.30%1.43%-79.84-80.651.001.96XA602_110:0023-May-050.22%91.49%0.45%-72.87-74.880.661.07XA602_110:0024-May-050.59%96.06%0.30%-73.58-75.430.760.91XA602_110:0025-May-050.48%95.34%1.33%-73.30-75.130.721.03XA602_119:0023-May-051.36%91.36%1.16%-74.91-76.400.960.86XA602_119:0024-May-050.25%94.57%0.90%-72.69-74.590.740.93XA602_119:0025-May-051.13%94.07%0.75%-74.35-75.890.700.98XA602_120:0023-May-050.83%94.63%0.75%-72.74-74.530.750.87XA602_120:0024-May-050.82%93.66%0.68%-73.44-74.830.840.92XA602_120:0025-May-050.68%90.26%0.43%-76.16-77.650.821.07XA619_110:0023-May-050.67%97.15%0.67%-81.82-79.130.721.33XA619_110:0024-May-050.00%93.67%0.62%-83.51-81.000.821.73XA619_110:0025-May-050.20%74.62%0.41%-87.25-84.710.941.78XA619_119:0023-May-050.52%94.35%0.00%-83.33-80.680.751.29XA619_119:0024-May-052.49%92.22%0.50%-81.58-80.480.691.13XA619_119:0025-May-050.41%97.01%0.41%-82.47-80.160.711.15XA619_120:0023-May-050.76%92.71%1.13%-82.91-80.190.711.61XA619_120:0024-May-050.68%94.50%0.00%-84.11-81.650.841.89XA619_120:0025-May-051.39%88.89%1.03%-86.02-83.500.911.43由此判断XA619-1过覆盖，对XA928-1形成邻频干扰。调整建议：将XA619-1的俯仰角增加3度。5.XA637-1过覆盖：问题描述：图示位置，占用XA637-1信号，通话质量较差。问题分析：测试中，手机占用XA637-1跳频信道，电平在68dBm左右，但是通话质量较差，话音质量在4级左右，TA12，从邻小区列表看，XA109-1电平高于XA637-1，且与XA637-1具有相同的跳频组，因此断定是XA637-1过覆盖，被周围同跳频组小区跳频干扰。调整建议：将XA637-1的俯仰角增加3度。6.XA389-0和XA389-2天馈线接反：问题描述：图示位置，占用XA107-2小区的跳频信道，电平75dBm,通话质量较差,话音质量7级。问题分析：从现象看，跳频干扰的可能性较大，从邻小区列表里发现XA389-2（BCCH=93,BISC=67）在此处电平较强（72dBm），覆盖区域与其地理位置不符，为此我们对基站XA389（紫薇二号站）进行了路测，结果发现XA389-0和XA389-2的天馈线接反。XA389_2（BCCH=93,BISC=67）覆盖如下图所示，本应该为0面覆盖区域XA389_0(BCCH=75,BISC=62)覆盖如下图所示，本应该为2面覆盖区域，并且与XA448-2造成同频BCCH干扰。调整建议：对接反的天馈线进行整改。7.XA602-0掉话分析：问题描述：图示位置，占用XA602-0（BCCH=89,BISC=67）信号，通话质量恶化，并掉话。问题分析：测试中，手机占用XA602-0小区的非跳频信道，TCH=89,电平在68dBm左右，通话质量较差，话音质量为7级，无法进行正常的切换，最后产生无线链路掉话，对这一区域进行频率检查，发现有同频的小区XA322-1距离掉话点仅250米，而且还发现XA223-0与XA602-1同频同色。具体如下：据此断定是XA322-1对XA602-0产生同频干扰。由于XA223-0与XA602-1同频同色码，且XA322-0和XA223-1都定义了和XA223-0的切换关系，所以导致大量的切出失败，具体如下：cellNameTimeDate切换成功率切换请求总数切出请求数切出执行数切出成功数切出执行失败数切出成功率XA223_110:0030-May-0585.03%8058457826849880.95%XA223_119:0030-May-0574.67%3373862962653168.65%XA223_120:0030-May-0586.04%3
