Description

发现无线网络问题的方法、 装置及系统 本申请要求于 2009年 2月 20日提交中国专利局、 申请号为 200910078405.6、 发明名称为"发现无线网络问题的方法、装置及系统,,的中国专利申请的优先权, 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及无线网络领域, 尤其涉及一种发现无线网络问题的方法、 装置 及系统。 背景技术
目前,在用户设备 UE进行无线网络接入的过程中,有可能会发生各种无线 网络问题,例如无线链路失败( Radio Link Failure, RLF )或切换失败( Hand Over Failure, HOF ) 、 切换过早、 切换过晚、 乒乓切换等问题。
当 UE发生 RLF问题时,会在指定时间内进行无线资源控制( Radio Resource Control, RRC ) 的重建, 若在指定时间内重建失败, 则 UE后继可以发起 RRC 建立请求; 当 UE收到切换命令,在指定时间内切换失败,即发生了 HOF问题时, 会在指定时间内进行 RRC重建过程, 同样若在指定时间内重建失败, 则 UE后继 也可以发起 RRC建立请求。 另外, 当 UE发生 RLF问题时, 可以把 UE在发生 RLF 之前待过的小区称为前服务小区 ( P-Cell ) , 其它小区统称为新小区 ( N-Cell ); 而当 UE发生了 HOF问题时,由于涉及到了切换概念,因此存在源小区(S-Cell )、 目标小区 ( T-Cell )和第三小区 ( O-Cell ) 。
举例来说, 当 UE发生 RLF问题时, 无线资源控制 RRC重建或建立的流程示 意图如图 1所示, 包括以下内容。
1、 UE发生了 RLF。
2、 UE发起 RRC连接重建或建立过程。
具体来说, UE可能在前服务小区 P-Cell或新小区 N-Cell进行 RRC连接重建; 或者在 RRC重建失败后, UE再发起后续的 RRC建立过程, 同样可以在前服务小 区或新小区上来建立。
当 UE进行切换, 并发生 HOF时, RRC重建或建立的流程示意图如图 2所示, 包括以下内容。
1、 源小区 (S-Cell )对 UE进行测量配置。
2、 UE进行相应的测量。
3、 如果测量结果满足设置的条件后, UE会上报测量报告给源小区。
4、 源小区根据 UE上报的测量报告决定将该 UE切换到目标小区(T-Cell ) 。 5、 S-Cell向 T-Cell发送切换请求消息。
6、 T-Cell向 S-Cell返回切换响应消息。
7、 S-Cell向 UE发送切换命令。
8、 此时如果 T-Cell的无线信号不是 4艮好, 就会导致 UE在指定时间内不能 正常地切换到 T-Cell。
9、 当 UE侧所设置的定时器超时后, UE就发生了 HOF, 此时就会发起 RRC 连接重建过程。
具体来说, UE可以在前一切换的 S-Cell或 T-Cell或第三小区 O-Cell来进行 RRC连接重建过程, 其中 O-Cell是指除 S-Cell及 T-Cell之外的小区; 或者在 RRC 重建失败后, UE再发起后续的 RRC建立过程, 同样的, 该 RRC建立过程也可以 在 S-Cell、 T-Cell或 O-Cell侧来进行。
从上述现有技术的方案可知, 现有技术中没有自动识别并发现这些无线网 络问题场景的方案, 这样就有可能导致后继由于参数设置的不合理而引起的各 种无线网络问题,例如切换过早或切换过晚等问题,从而导致 UE出现掉话的现 象, 影响了用户的使用。 发明内容
