Description

一种无线链路检测方法及相关装置 技术领域
本发明涉及无线通信领域, 特别涉及一种无线链路检测方法及相关装置。
背景技术
在无线通信网络中, 一个用户设备(User Equipment, UE )可以同时具有 至少两个服务小区, 其中的一个称为主小区 (Primary Cell, PCell ), 其余的称 为辅小区 ( Secondary Cell, SCell )。
UE可以在 PCell和至少一个 SCell上向基站 ( Base Station, BS )发送物 理上行控制信道 ( Physical Uplink Control Channel, PUCCH ), UE可以发送 PUCCH的 SCell可以称为主辅小区 ( Primary Secondary Cell, PSCell )。 PCell 和每一个 PSCell分别属于不同的小区组。以 UE只有一个 PSCell的情况为例, 此时 PCell所在的小区组可以称为第一' 区组, PSCell所在的小区组可以称为 第二小区组。
BS配置 UE对 PCell进行无线链路监测 ( Radio Link Monitoring, RLM ), 在 RLM中 UE对 PCell的信号质量进行测量, UE根据 RLM的信号质量测量 结果判断 PCell是否发生了无线链路失败( Radio Link Failure, RLF )。 一旦判 断 PCell发生了 RLF, UE发起无线连接重建过程, 在该重建过程中, UE释放 所有 SCell, 执行小区选择, 并且向选中的小区请求连接重建。 所谓释放所有 SCell即删除所有和该 SCell相关的配置。
但是, 当 PCell没有发生 RLF时, UE的某个 PSCell的信号质量可能已经 比较差,甚至可能已经与该 UE失步。此时, UE在该 PSCell上发送 PUCCH, 会造成上行干扰。

三、 激活没有发生 RLF的小区组
上述第三信息可以是 BS发送的激活消息, 具体地, BS可以选择一个没 有发生 RLF的小区组,然后向 UE发送激活消息以命令 UE激活相应的小区组。
以第一 PSCell所在的小区组发生了 RLF为例, 此时 BS 可以选择第二 PSCell所在的小区组, 然后向 UE发送一条激活消息, 该激活消息中包含用于 激活该第二 PSCell所在小区组的标志或者包含该第二 PSCell所在小区组的标 识, UE在收到该激活消息后激活相应的小区组。
所谓激活一个小区组, 即 UE开始在该小区组的无线链路上接收下行并且 开始在该小区组的无线链路上发送上行。
可以理解的是, 以上仅列举了 BS配置 UE以使 UE从当前 RLF中恢复的 几种可选操作方式,对于以上从无线链路失败状态中恢复的操作方式具体不作 限定。
本发明实施例中,通过基站向上述用户设备发送第三信息, 以使得上述用 户设备根据该第三信息从无线链路失败状态中恢复, 从而进入正常工作状态。
上述实施例中,基站设备还可以向用户设备发送第二配置信息对上述主小 区做第二无线链路监测, 请参阅图 22, 本发明实施例中无线链路监测方法另 一实施例包括:
2201、基站接收用户设备在该用户设备的主小区和主辅小区上分别发送的 物理上行控制信道;
BS接收 UE在该 UE的 PCell和 PSCell上分别发送的 PUCCH, 其中, 该 PSCell为该 UE向该 BS发送 PUCCH的 SCell;
2202、上述基站向上述用户设备发送第一配置信息, 以使得上述用户设备 根据上述第一配置信息确定上述主辅小区发生无线链路失败后停止在上述主 辅小区上向上述基站发送物理上行控制信道;
上述 BS向上述 UE发送第一配置信息, 以使得该 UE根据该第一配置信 息确定上述 PSCell发生 RLF后停止在该 PSCell上向该 BS发送 PUCCH; 其 中, 该第一配置信息用于该 UE对该 PSCell做第一 RLM。
需要说明的是, 该 PSCell属于该 UE的服务小区, 该 UE可以有至少一个 PSCell,对于 PSCell的个数此处不作限制。该 UE根据从 BS获取的用于 RLM 的参数对该 UE的 PSCell进行 RLM。 例如, 以该 UE具有 2个 PSCell的情况 为例, 此时该 UE获取该 BS发送的二套用于 RLM的参数, 分别是:
• 定时时长 T310-1 , 计数值 N310-1 , 计数值 N311-1 ;
• 定时时长 T310-2, 计数值 N310-2, 计数值 N311-2。
UE使用 T310-1 , N310-1和 N311-1对第一 PSCell进行 RLM, 具体过程 如下:
例如, 定时时长 T310-1设置为 10秒, 计数值 N310-1设置为 3, 计数值 N311-1设置为 2;
若 UE连续 N310-1次(例如 3次)监测到和第一 PSCell失步, 则 UE使 用定时时长 T310-1打开第一定时器, 即从 0秒开始计时或从 T310-1 (例如 10 秒)开始倒计时;
若 UE连续 N311-1次(例如 2次 )监测到和第一 PSCell同步且第一定时 器已经打开, 则 UE关闭第一定时器;
若第一定时器超时即超过 T310-1 (例如 10秒) 的门限值, 则 UE探测到 第一 PSCell发生 RLF;
UE使用 T310-2, N310-2和 N311-2对第二 PSCell进行 RLM, 具体过程 与 UE对第一 PSCell进行 RLM的过程相同。 同样的,对于其余的 PSCell进行 RLM的具体过程与上述类似, 此处不再赘述。

上述 BS向上述 UE发送第二配置信息, 以使得该 UE根据该第二配置信 息确定上述 PCell发生 RLF后停止在该 PCell上向该 BS发送 PUCCH; 其中, 该第二配置信息用于该 UE对该 PCell做第二 RLM。
需要说明的是, 该 BS向该 UE发送第二配置信息, 还可以使得该 UE根 据该第一配置信息和该第二配置信息确定该 PSCell和该 PCell均发生 RLF后 进行连接重建。
2204、上述基站接收上述用户设备发送的第一信息, 该第一信息用于指示 上述主辅小区发生无线链路失败;
上述 BS接收上述 UE发送的第一信息, 该第一信息用于指示上述 PSCell 发生 RLF。该第一信息中可以包含以下信息中至少一种: PSCell的标识、 PSCell 所在小区组的标识、 PSCell的小区标识。该第一信息中还可以包含上述 PSCell 发生 RLF的原因, 该失败原因可以是步骤 2202中第一定时器超时。 对于以上 第一信息中包含的区分信息此处不作限定。

上述 BS向上述 UE发送第三信息, 以使得该 UE根据该第三信息从 RLF 状态中恢复; 该第三信息包含以下四项中至少一项: 该主辅小区的标识、 该主 辅小区所在小区组的标识、没有发生无线链路失败的主辅小区的标识、没有发 生无线链路失败的主辅小区所在小区组的标识; 上述从 RLF状态中恢复的方 式参见步骤 2104, 此处不再赘述。
2206、上述基站接收上述用户设备发送的第二信息, 该第二信息用于指示 上述主小区发生无线链路失败;
上述 BS接收上述 UE发送的第二信息, 该第二信息用于指示上述 PCell 发生 RLF; 该第二信息与上述步骤 2204中第一信息包含的内容类似, 此处不 再赘述。其中该第二信息与该第一信息可以是不同的消息,也可以是同一条消 息。 当是同一条消息时, 该消息需要携带区分信息, 该区分信息用于帮助 BS 区分当前是 PCell发生了 RLF,还是 PSCell发生了 RLF。当 UE具有多个 PSCell 的时候,该区分信息还用于帮助 BS区分当前是哪一个 PSCell发生了 RLF。具 体的, 该区分信息可以是以下至少一种:
一、 PCell标志或者 PSCell标志, 当该消息包含 PCell标志时 BS获知当 前 PCell发生了 RLF,当该消息包含 PSCell标志时 BS获知当前 PSCell发生了 RLF;
二、 PCell或者 PSCell所在小区组的标识, 当该消息包含 PCell所在小区 组的标识时 BS获知当前 PCell发生了 RLF, 当该消息包含 PSCell所在小区组 的标识时 BS获知当前 PSCell发生了 RLF;
三、 PCell或者 PSCell的小区标识, 当该消息包含 PCell的小区标识时 BS 获知当前 PCell发生了 RLF, 当该消息包含 PSCell的小区标识时 BS获知当前 PSCell发生了 RLF。
同样的, 该 UE用于指示 PCell发生 RLF的消息或者用于指示 PSCell发 生 RLF的消息中还可以包含失败的原因, 例如可以是步骤 2202中 T310-1超 时或者 T310-2超时, 具体此处不作限制。
2207、上述基站向上述用户设备发送第四信息, 以使得该用户设备根据该 第四信息从无线链路失败状态中恢复。

一、 释放发生 RLF的 PCell所在的小区组
具体地, 上述第四信息可以是 BS发送的一条重配置消息, 该重配置消息 中包含 PCell所在小区组的标识或者用于释放 PCell所在小区组的标志。当 UE 接收到该重配置消息后, 根据其中的标识或者标志释放 PCell所在的小区组。 所谓释放 PCell所在的小区组, 即 UE删除与该小区组相关的配置。
二、 去激活发生 RLF的 PCell所在的小区组
具体地, 上述第四信息可以是 BS发送的一条去激活消息, 该消息中包含 该 PCell所在小区组的标识或者用于去激活该 PCell所在小区组的标志。当 UE 接收到该去激活消息后,根据其中的标识或者标志去激活 PCell所在的小区组。
所谓去激活 PCell所在的小区组, 即 UE停止在该小区组的无线链路上发 送上行并且 UE停止在该小区组的无线链路上接收下行。
三、 激活没有发生 RLF的小区组
上述第四信息可以是 BS发送的激活消息, 具体地, BS可以选择一个没 有发生 RLF的小区组,然后向 UE发送激活消息以命令 UE激活相应的小区组。 以 PCell所在的小区组发生了 RLF为例, 此时 BS可以选择一个 PSCell 所在的小区组, 然后向 UE发送一条激活消息, 该激活消息中包含用于激活该 PSCell所在小区组的标志或者包含该 PSCell所在小区组的标识, UE在收到该 激活消息后激活相应的小区组。
所谓激活一个小区组, 即 UE开始在该小区组的无线链路上接收下行并且 开始在该小区组的无线链路上发送上行。
可以理解的是, 以上仅列举了 BS配置 UE以使 UE从当前 RLF中恢复的 几种可选操作方式,对于以上从无线链路失败状态中恢复的操作方式具体不作 限定。
本发明实施例中, 上述基站向上述用户设备发送第二配置信息, 以使得该 用户设备根据该第二配置信息确定上述主小区发生无线链路失败后停止在该 主小区上向该基站发送物理上行控制信道; 避免用户设备释放所有的辅小区, 进行小区选择并请求连接重建, 从而避免了数据传输中断。
为便于理解,下面以一具体应用场景对本发明实施例中无线链路检测方法 进行具体描述:
BS接收 UE在该 UE的 PCell和 PSCell上分别发送的 PUCCH, 以该 UE 具有 2个 PSCell的情况为例, PCell所属的小区组为第一小区组, 第一 PSCell 所在的小区组为第二小区组, 第二 PSCell所在的小区组为第三小区组; BS向 UE发送三套用于 RLM的参数, 分别是:
· 定时时长 T310, 计数值 N310, 计数值 N311 ;
• 定时时长 T310-1 , 计数值 N310-1 , 计数值 N311-1 ;
• 定时时长 T310-2, 计数值 N310-2, 计数值 N311-2。
例如, 定时时长 T310设置为 20秒, 计数值 N310设置为 3, 计数值 N311 设置为 2; 定时时长 T310-1设置为 10秒, 计数值 N310-1设置为 3, 计数值 N311-1设置为 2; 定时时长 T310-2设置为 10秒, 计数值 N310-2设置为 3, 计数值 N311-2设置为 2;
UE使用 T310、 N310和 N311对 PCell进行 RLM, 具体过程如下: 若 UE连续 N310次(例如 3次)次监测到和 PCell失步, 则 UE使用定时 时长 T310打开第一定时器, 即从 0秒开始计时或从 T310 (例如 20秒 )开始 倒计时;
若 UE连续 N311次(例如 2次)监测到和 PCell同步且第一定时器已经 打开, 则 UE关闭第一定时器;
若第一定时器超时即超过 T310(例如 20秒)的门限值,则 UE探测到 PCell 发生 RLF。
UE使用 T310-1 , N310-1和 N311-1对第一 PSCell进行 RLM, 具体过程 ^口下:
若 UE连续 N310-1次(例如 3次)监测到和第一 PSCell失步, 则 UE使 用定时时长 T310-1打开第二定时器, 即从 0秒开始计时或从 T310-1 (例如 10 秒)开始倒计时;
若 UE连续 N311-1次(例如 2次 )监测到和第一 PSCell同步且第二定时 器已经打开, 则 UE关闭第二定时器;
若第二定时器超时即超过 T310-1 (例如 10秒) 的门限值, 则 UE探测到 第一 PSCell发生 RLF。
UE使用 T310-2, N310-2和 N311-2对第二 PSCell进行 RLM, 具体过程 与 UE对第一 PSCell进行 RLM的过程相同。
当 UE对第一 PSCell进行 RLM探测到该 UE的第一 PSCell发生 RLF后, 该 UE停止在该第一 PSCell上向上述 BS发送 PUCCH, 并将该第一 PSCell发 生 RLF 的信息通过与第一小区组或者第三小区组之间的无线链路指示给该 BS。: BS收到该指示后,向 UE发送另一指示信息,该指示信息中包含第一 PSCell 所在小区组的标识, 当 UE接到该指示信息后, 根据其中的标识执行相应的操 作方式使得 UE从当前 RLF中恢复。
当 UE对第二 PSCell进行 RLM探测到该 UE的第二 PSCell发生 RLF后, 该 UE停止在该第二 PSCell上向上述 BS发送 PUCCH, 并将该第二 PSCell发 生 RLF 的信息通过与第一小区组或者第二小区组之间的无线链路指示给该 BS。: BS收到该指示后,向 UE发送另一指示信息,该指示信息中包含第二 PSCell 所在小区组的标识, 当 UE接到该指示信息后, 根据其中的标识执行相应的操 作方式使得 UE从当前 RLF中恢复。
当 UE对 PCell进行 RLM探测到该 UE的 PCell发生 RLF后,该 UE停止 在该 PCell上向上述 BS发送 PUCCH,并将该 PCell发生 RLF的信息通过与第 二小区组或者第三小区组之间的无线链路指示给该 BS。 BS收到该指示后, 向 UE发送另一指示信息, 该指示信息中包含 PCell所在小区组的标识, 当 UE 接到该指示信息后,根据其中的标识执行相应的操作方式使得 UE从当前 RLF 中恢复。
当 UE对上述 PSCell和上述 PCell分别进行 RLM并探测到该 UE的 PCell、 第一 PSCell以及第二 PSCell均发生 RLF后, 该 UE释放所有 SCell, 执行小 区选择, 并且向选中的小区请求连接重建。
以上实施例仅用以说明本发明的技术方案, 而非对其限制; 尽管参照前述 实施例对本发明进行了详细的说明, 本领域的普通技术人员应当理解: 其依然 可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进 行等同替换; 而这些修改或者替换, 并不使相应技术方案的本质脱离本发明各 实施例技术方案的精神和范围。
