概述为了后续的LTE网络CSFB流程优化做准备，对近期LTE网络的CSFB流程各指标进行取样分析。提取指标时间范围为8月5日全天。指标分析在此先将韶关瑞原平台与省公司博瑞德平台指标进行比较。瑞原平台博瑞德平台比较差值成功率平均时延成功率平均时延成功率平均时延CSFB被叫回落98.71%161.26363.04%2544.58435.67%-2383.321CSFB主叫回落98.78%128.07571.65%1998.62727.13%-1870.552CSFB回落98.75%143.90867.22%2262.25031.53%-2118.342从比较中可以明显发现，韶关瑞原平台与省公司博瑞德平台指标有着巨大的差异，瑞原平台的CSFB指标要大大优于博瑞德平台。而由于发起流程的不同，CSFB被叫回落的时延要较CSFB主叫回落高25.9%。维度分析在此对瑞原平台8月5日全天的CSFB指标分维度进行分析。MME维度分析取各MME于8月5日全天CSFB指标。MMECSFB被叫回落CSFB主叫回落尝试次数成功次数成功率平均时延尝试次数成功次数成功率平均时延GZMME120129220828797098.55%161.606632016431587698.66%128.1136GZMME130130711930179598.27%160.673733460332951498.48%127.7619GZMME150230396430104699.04%161.375733212532881699.00%128.5309GZMME160128658228376099.02%161.421331644231324898.99%127.8873可见各MME的CSFB指标均良好。CSFB被叫回落的时延同样较CSFB主叫回落高要高。小区维度分析于小区维度上为了更高的准确性，我们取各小区于8月4日至8月6日三天内全天的CSFB指标。提取时段匹配的CSFB主叫回落业务2950个CI中，成功率低于96%的共有41个，占比1.39%；CSFB被叫回落业务2949个CI中，成功率低于96%的共有47个，占比1.59%。如下表：成功率CSFB主叫回落CSFB被叫回落小区数小区占比小区数小区占比低于70%20.07%10.03%70%至90%50.17%120.41%90%至96%341.15%341.15%96%至98%913.08%1003.39%98%以上281895.53%280295.02%在此分别输出主叫回落和被叫回落三天业务次数大于100次的成功率低于96%小区。类型小区尝试次数成功次数成功率平均时延CSFB主叫回落韶关火车站D-ELH-22712240588.68%126.844CSFB主叫回落韶关仁化新市场D-ELH-22962264089.13%117.878CSFB主叫回落韶关火车站D-ELH-360954389.16%118.372CSFB主叫回落韶关仁化新市场D-ELH-32771248889.79%129.943CSFB主叫回落韶关火车站D-ELH-12581231889.81%115.403CSFB主叫回落韶关仁化新市场D-ELH-16339570990.06%125.132CSFB主叫回落韶关小岛饭店D-ELH-11557141490.82%106.451CSFB主叫回落韶关建国路D-ELH-31894172290.92%118.387CSFB主叫回落韶关建国路D-ELH03%109.153CSFB主叫回落韶关小岛饭店D-ELH-21356123991.37%120.776CSFB主叫回落韶关小岛饭店D-ELH-31603146991.64%116.104CSFB主叫回落韶关利民D-ELH-274468792.34%99.089CSFB主叫回落韶关仁化农业银行D-ELH-12377223193.86%124.605CSFB主叫回落韶关利民D-ELH-31961184193.88%104.611CSFB主叫回落韶关仁化农业银行D-ELH-3105599193.93%134.724CSFB主叫回落韶关利民D-ELH-11124105894.13%125.664CSFB主叫回落韶关仁化农业银行D-ELH-240137994.51%121.034CSFB主叫回落韶关香蜜园D-ELH-21978187094.54%115.939CSFB主叫回落韶关烟雨楼台D-ELH-214814094.59%110.764CSFB主叫回落韶关南雄梅岭2F-ELH-212011495.00%126.860CSFB主叫回落韶关曲江南约F-ELH-310910495.41%109.817CSFB主叫回落韶关工业西齿轮厂D-ELH-397693395.59%120.416CSFB主叫回落韶关莲花北路D-ELH-312211795.90%101.350CSFB主叫回落韶关香蜜园D-ELH-11131108595.93%120.049CSFB主叫回落韶关工业西齿轮厂D-ELH-21951187295.95%114.089CSFB被叫回落韶关仁化新市场D-ELH32%152.219CSFB被叫回落韶关火车站D-ELH-12313207089.49%153.800CSFB被叫回落韶关乐昌张溪F-ELH-339535489.62%178.542CSFB被叫回落韶关火车站D-ELH-22526226489.63%163.000CSFB被叫回落韶关仁化新市场D-ELH-32406215989.73%154.748CSFB被叫回落韶关仁化新市场D-ELH-22611234389.74%155.881CSFB被叫回落韶关小岛饭店D-ELH-21232110789.85%146.360CSFB被叫回落韶关火车站D-ELH-357351790.23%147.872CSFB被叫回落韶关小岛饭店D-ELH-11291116690.32%143.545CSFB被叫回落韶关建国路D-ELH-32042184890.50%153.725CSFB被叫回落韶关小岛饭店D-ELH-31475134591.19%146.257CSFB被叫回落韶关建国路D-ELH-12930267691.33%151.278CSFB被叫回落韶关乐昌转村F-ELH-115514392.26%94.671CSFB被叫回落韶关利民D-ELH-263058292.38%144.797CSFB被叫回落韶关利民D-ELH-11117103292.39%169.671CSFB被叫回落韶关仁化农业银行D-ELH-238735892.51%156.640CSFB被叫回落韶关仁化韶音亭F-ELH-114913892.62%134.355CSFB被叫回落韶关仁化观日亭F-ELH-265360592.65%138.593CSFB被叫回落韶关仁化农业银行D-ELH-388882492.79%156.150CSFB被叫回落韶关利民D-ELH-31744162393.06%143.148CSFB被叫回落韶关仁化观日亭F-ELH-135533895.21%136.340CSFB被叫回落韶关仁化农业银行D-ELH-12045195195.40%155.325CSFB被叫回落韶关新丰龙文F-ELH-354552095.41%145.379CSFB被叫回落韶关曲江苏拱F-ELH-254051695.56%150.107CSFB被叫回落韶关乳源茶园底F-ELH-11955187295.75%157.648CSFB被叫回落韶关香蜜园D-ELH-21946186495.79%156.554CSFB被叫回落韶关韶医科教楼D-ELH-238637095.85%140.414用户维度分析同样的，取用户维度8月5日全天CSFB指标。在此分别输出主叫回落和被叫回落当天业务次数TOP10的用户。于用户维度上，并没有明显的集中性，当天CSFB流程次数较多的前十用户都有着较高的成功率。类型IMSI尝试次数成功次数成功率CSFB主叫回落所有用户1303334128745498.78%CSFB主叫回落（空白）23895923441098.10%CSFB主叫回落46002020568163230830699.35%CSFB主叫回落460020350327534145145100.00%CSFB主叫回落46000986562375913713699.27%CSFB主叫回落46000986574405613413399.25%CSFB主叫回落460001632176596125125100.00%CSFB主叫回落46000986577233112512398.40%CSFB主叫回落46000076072386212112099.17%CSFB主叫回落46000788420817411611498.28%CSFB主叫回落46000986564676811211199.11%CSFB主叫回落460028165085349110110100.00%CSFB被叫回落所有用户1189873117457198.71%CSFB被叫回落（空白）21654521169797.76%CSFB被叫回落46000220895563461661499.68%CSFB被叫回落46000008149346652552399.62%CSFB被叫回落46000792325923740640299.01%CSFB被叫回落46007915563746835435299.44%CSFB被叫回落46000794322315411811496.61%CSFB被叫回落460020156773964114114100.00%CSFB被叫回落46000986565145111311299.12%CSFB被叫回落46002999922855210610599.06%CSFB被叫回落460009780369665100100100.00%CSFB被叫回落460007512222660989798.98%失败原因分析对8月5日全天CSFB流程的失败原因进行分析。类型失败原因失败次数CSFB主叫回落release-due-to-eutran-generated-reason5606CSFB主叫回落unspecified2014CSFB主叫回落interaction-with-other-procedure701CSFB主叫回落x2-handover-triggered649CSFB主叫回落user-inactivity178CSFB主叫回落Timeout150CSFB主叫回落radio-connection-with-ue-lost61CSFB主叫回落handover-desirable-for-radio-reason51CSFB主叫回落s1-intra-system-handover-triggered17CSFB主叫回落interrat-redirection8CSFB主叫回落failure-in-radio-interface-procedure4CSFB主叫回落ho-failure-in-target-EPC-eNB-or-target-system4CSFB被叫回落release-due-to-eutran-generated-reason4806CSFB被叫回落unspecified2053CSFB被叫回落interaction-with-other-procedure1513CSFB被叫回落x2-handover-triggered238CSFB被叫回落Timeout71CSFB被叫回落user-inactivity66CSFB被叫回落radio-connection-with-ue-lost12CSFB被叫回落failure-in-radio-interface-procedure7CSFB被叫回落han
