在实际应用过程中,当出现下行数据链路故障时,例如,核心网出现下行路由故障、计费鉴权系统故障等时,终端设备通常可以发送上行数据,但终端设备无法接收到核心网侧发送的下行数据,导致用户无法通过终端设备获取正常的数据业务。该种情况下,用户通常需要根据个人经验重开终端设备的数据开关、或者开启并关闭终端设备的飞行模式等,以实现终端设备可以正常获取数据业务。
然而,在上述过程中,用户可以明显感知到上网故障,并需要依赖用户的个人经验解决网络故障,导致用户体验差。

在上述过程中,可以自动对下行数据链路故障进行检测,且在检测到下行数据链路故障时,可以自动对下行数据链路故障进行修复,使得用户不会再感知到网络出现故障,也无需用户手动进行修复,进而提高用户体验。

另一种可行的实现方式:
判断数据链路层中上行缓冲队列中的数据单元的数量是否小于第二阈值、且数据链路层中下行缓冲队列中的数据单元是否大于第三阈值;
若是,则重新获取IP连接资源;
若否,重建RRC连接,并判断下行数据链路故障是否被修复,若判断下行数据链路故障未被修复,则重新获取IP连接资源。
在另一种可能的实施方式中,重建RRC连接,包括:
确定终端设备当前连接的基站;
重建与基站之间的RRC连接。
通过重建终端设备和基站之间的RRC连接,可以确定终端设备和基站之间可以正常通信。

确定发送上行数据时使用的第一PDN连接;
判断终端设备当前存在的公共数据网络PDN连接数量是否大于1;
若是,断开、重建第一PDN连接;
