Description

切换故障的检测、检测处理方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种切换故障的检测、检测处理方法及装置。
背景技术
长期演进(Long Term Evolution，简称为LTE)系统中，用户设备(User Equipment，简称为UE)需要在LTE系统与通用陆地无线接入网络(Universal Terrestrial Radio Access Network，简称为UTRAN/UMTS陆地无线接入网络)或GSM/EDGE无线接入网络(GSM EDGE Radio Access Network，简称为GERAN)系统之间执行切换。
在LTE网络与UTRAN或GERAN网络重叠覆盖的区域，UE移动到LTE小区边缘后，需要发起切换。如果在LTE小区边缘与其他LTE小区以及UTRAN或GERAN小区覆盖都有重叠，那么UE移动到此处后可以选择切换到LTE小区也可以切换到UTRAN或GERAN小区。对于LTE UE，需要尽量使其驻留在LTE网络内接受服务。
但是由于切换参数设置不合适，在交叠覆盖区域，UE向LTE邻区切换条件比UE向UTRAN或GERAN切换更难满足，那么此时在LTE小区和UTRAN或GERAN小区信号强度相同的情况下，UE就可能切换到UTRAN或GERAN小区，这种切换是不必要的。

针对相关技术中存在的上述问题，下面结合可选实施例进行说明，在下述可选实施例中结合了上述可选实施例及其可选实施方式。
本可选实施例主要说明了当UE在执行系统间切换时，发生由于切换参数不合适而导致的切换过早或切换过晚时，如何将这些类型的切换失败检测出来。
下面以在LTE侧如何检测UE从LTE到异系统发生不必要切换为例进行说明。
首先明确场景，LTE小区与UTRAN或GERAN小区覆盖交叠，在LTE小区覆盖的边缘区域，LTE邻区和UTRAN、GERAN小区的信号强度相近。UE从LTE小区中心向LTE、UTRAN、GERAN小区交叠覆盖区移动。UE未向LTE邻区发起切换，而向UTRAN、GERAN小区切换，发生不必要切换。不必要切换场景示意图如图5所示。
图6是根据本发明实施例的不必要切换检测流程示意图，如图6所示，LTE基站服务小区在给UE下发异系统移动性测量控制信令(B2Event)时，判断如果服务小区配置了其他LTE邻区，则在下发B2测量时，一起下发LTE移动性测量控制(A5Event)，其中B2和A5事件测量配置中的服务小区门限设置成一致，记录为B2-1thd和A5-1thd。A5事件的测量上报次数设置成infinity。A5事件中的邻区门限与B2事件中的邻区门限设置的相近。这样基站在收到B2测量报告前后一段时间内，能够充分获取到通过UE上报的A5事件测量结果包含的LTE邻区信息。根据UE在LTE小区执行业务所需的信号强度经验值设置检测门限值Threshold。
基站收到B2和A5事件测量结果后，判断不必要切换判断原则：
1.UE上报B2事件结果并从LTE小区向异系统邻区发生切换。
2.在基站收到UE上报B2的时间点前后一段时间Duration内(0～100秒)，基站能收到UE上报的A5事件。
3.A5事件上报的服务小区信号和/或LTE邻区信号满足门限值Threshold。
实施例1：
图7是根据本发明实施例的不必要切换检测实施例1示意图，下面结合附图7，对如下场景的不必要切换故障检测流程做如下说明：
如图7所示：
执行图7中的步骤S702，UE在LTE小区中移动到小区边缘区域时，LTE小区为UE下发B2事件测量配置和A5事件测量配置。
执行图7中的步骤S704，UE上报B2测量报告，携带服务小区和UTRAN邻区(GERAN邻区)的测量结果。
执行图7中的步骤S706，Duration时间范围内，UE上报A5测量报告，携带服务小区和LTE邻区的测量结果。
执行图7中的步骤S708，A5事件上报的LTE邻区信号满足门限值Threshold，检测到LTE到异系统不必要切换。
实施例2：
图8是根据本发明实施例的不必要切换检测实施例2示意图，下面结合附图8，对如下场景的不必要切换故障检测流程做如下说明：
如图8所示：
执行图8中的步骤S802，UE在LTE小区中移动到小区边缘区域时，LTE小区为UE下发B2事件测量配置和A5事件测量配置。
执行图8中的步骤S804，UE上报B2测量报告，携带服务小区和UTRAN邻区(GERAN邻区)的测量结果。
执行图8中的步骤S806，Duration时间范围内，UE上报A5测量报告，携带服务小区和LTE邻区的测量结果。
执行图8中的步骤S808，A5事件上报的服务小区信号满足门限值Threshold，检测到LTE到异系统不必要切换。
实施例3：
图9是根据本发明实施例的不必要切换检测实施例3示意图，下面结合附图9，对如下场景的不必要切换检测流程做如下说明：
如图9所示：
执行图9中的步骤S902，UE在LTE小区中移动到小区边缘区域时，LTE小区为UE下发B2事件测量配置和A5事件测量配置。
执行图9中的步骤S904，UE上报B2测量报告，携带服务小区和GERAN邻区(UTRAN邻区)的测量结果。
执行图9中的步骤S906，Duration时间范围内，UE上报A5测量报告，携带服务小区和LTE邻区的测量结果。
执行图9中的步骤S908，A5事件上报的服务小区信号和LTE邻区信号满足门限值Threshold，检测到LTE到异系统不必要切换。
综上所述，通过本发明解决了相关技术中不能将不必要切换现象检测出来的问题，进而达到了能够将不必要切换的现象检测出来的效果。
