太仓地区跨BSC间出小区切换分析1.1 BSC间出小区切换整治 问题描述打开测量观察与上海的切换情况，涉及参加切换的一共5个基站，统计如下：BSC间切出成功率都为0%，出小区有切换请求次数但却无切换成功次数。时间GCELL_GCELL目标的LAC目标的CI出小区切换请求次数出小区切换失败次数出小区切换成功次数出小区无线切换成功率08:00:00G-浮桥陆公-2518216403110009:00:00G-浮桥陆公-2518216403330010:00:00G-华能电厂-1518217283330011:00:00G-华能电厂-1518217283110012:00:00G-华能电厂-15182172832230007:00:00G-璜泾新海村-1518217283110009:00:00G-璜泾新海村-1518217283110010:00:00G-璜泾新海村-1518217283660012:00:00G-璜泾新海村-1518217283420013:00:00G-璜泾新海村-1518217283430007:00:00G-鹿河搪瓷厂-1518217283330009:00:00G-鹿河搪瓷厂-1518217283330010:00:00G-鹿河搪瓷厂-1518217283770011:00:00G-鹿河搪瓷厂-1518217283110012:00:00G-鹿河搪瓷厂-1518217283330013:00:00G-鹿河搪瓷厂-1518217283330011:00:00G-鹿河搪瓷厂-2518217283110008:00:00G-太海汽渡-1518217283330011:00:00G-太海汽渡-15182172831100 问题分析有切换请求次数，但无切换命令次数下发，怀疑为苏州数据问题或上海数据问题，建议：1、 检查外部小区的BSIC、LAC、BCCH定义是否错误2、 检查交换GT与MSC交换中心定义是否错误 处理结果1、 苏州交换中心定义上海的GT数据存在错误，处理后的出小区切换指标正常，详情如下：时间GCELL_GCELL目标的LAC目标的CI出小区切换请求次数出小区切换失败次数出小区切换成功次数出小区无线切换成功率14:00:00G-荡茜-251821731310110014:00:00G-浮桥童桥村-151821730310110014:00:00G-浮桥童桥村-151821731330310014:00:00G-华能电厂-151821731310110014:00:00G-璜泾新海村-151821728340410014:00:00G-鹿河搪瓷厂-151821728310110014:00:00G-鹿河搪瓷厂-251821728320210014:00:00G-仪桥-151821730330310015:00:00G-浮桥陆公-151821731320210015:00:00G-浮桥陆公-251821730310110015:00:00G-浮桥童桥村-151821731310110015:00:00G-华能电厂-151821728320110015:00:00G-华能电厂-251821730310110015:00:00G-华能电厂-251821731330310015:00:00G-璜泾新海村-151821728320110015:00:00G-鹿河搪瓷厂-151821728330310015:00:00G-鹿河搪瓷厂-251821728320210015:00:00G-仪桥-1518217303202100 BSC间出小区切换成功率优化变化情况修改后观察BSC间出小区的切换情况，整个BSC的切出成功率指标较好，详情如下：起始时间时间BSC整体BSC间出小区切换成功率12/11/201007:00:0092.25312/11/201008:00:0091.03712/11/201009:00:0091.9812/11/201010:00:0090.94512/11/201011:00:0093.64212/11/201012:00:0093.36912/11/
