异系统切换问题
TD站点做3/2G切换操作时,满足异系统切换条件,3A测量报告也发了,但就是不向2G切换,向CN发重定位请求后,CN直接释放,释放原因为“om intervention”,请高手指点。(测试站点共3个小区,1、2小区切无法切换,但3小区异系统切换正常)
异系统邻区没有问题,再次测试发现,1、2小区无法切换只是和部分G网小区无法切换,和其它G网邻区又能正常切换,不知道问题出在那?

从楼主的描述看,很可能是1、2小区漏配了相关2G邻区。建议重新核查一下邻区关系和切换参数设置。

邻区检查了,无漏配情况,从后台指标统计情况来看,1、2小区有发生异系统切换,且成功率为100%,只是对某一G网站点小区切换时会出现上述情况,不知道具体原因是什么?
2G那边小区信息变改了~~导致无法切换咯~~3A测量报告上去了~~RNC也进行相应处理并告诉CN进行2/3G切换,CN一般回应重定位失败~~~

询问局方负责2G网络的工程技术人员,是不是那个2G站点的网络参数(BCCH、BSIC等)做过修改,而没有通知3G侧,所以3G网络这边没有相应更新该站点的2G网络信息?
