Description

一种终端、基站及其发送失败信息的方法
【技术领域】
本发明涉及通信技术领域，特别是涉及一种终端、基站及其发送失败信息的方法。

现有技术中终端在读取系统消息失败时，会导致基站出现误判。例如，在终端读取系统失败后，数据传输无法正常进行导致终端发生无线链路失败（Radio Link Failure，RLF），终端与基站进行重建，基站会误判终端在小区发生切换过晚，而实际应该切换过早或切换到错误小区。
【发明内容】
有鉴于此，本发明实施例提供了一种终端、基站及其发送失败信息的方法，以解决在终端读取系统消息失败时，造成基站出现误判的问题。
第一方面提供一种发送失败信息的方法，其包括：终端从第一小区切换到第二小区；终端读取第二小区的系统消息失败，在终端发生无线链路失败RLF时，则终端向进行无线资源控制协议RRC重建立或者RRC连接建立的第三小区所属的基站发送失败信息，以使基站根据失败信息确定终端的状态，其中失败信息包括失败原因值，失败原因值为读取系统消息失败。
