Description

一种无线链路监测方法、相关设备和系统 技术领域
本发明实施例涉及通信领域，尤其涉及一种无线链路监测方法、相关设备和系统。
背景技术
随着分组业务和智能终端的迅速发展，高速、大数据量业务对频谱的需求不断增加。根据最新发布的FCC国际频谱白皮书，未授权频谱资源要大于授权频谱资源。未授权频谱包括用于工业、科学和医疗(ISM，Industrial、Scientific and Medical)等设备的频段，如在美国有三个频段902-928MHz、2400-2484.5MHz及5725-5850MHz，2.4GHz为各国共同的ISM频段。ISM频段上使用的主要技术是无线保真(WiFi，Wireless Fidelity)或称为无线局域网(WLAN，wireless local network)、蓝牙、紫蜂(Zigbee)等。WiFi基于电子电气工程师协会(IEEE，Institute ofElectrical and Electronics Engineers)802.11系列标准，如802.11a、802.11n、802.11ac等。WiFi在服务质量(QoS，quality ofservice)、多用户调度(scheduling)等方面效率较低，移动性管理(mobility management)功能有限。
第三代合作伙伴项目(3GPP，the 3rd generation partnership project)高级长期演进(LTE-A，Long Term EvaluationAdvanced)研究项目授权频率辅助的接入(LAA，licensed assisted access)正在研究将LTE-A蜂窝通信技术应用在非授权频段，以更有效利用非授权频段资源，提高LTE用户的可用频谱带宽。如图1a和1b所示，LAA基于的场景是授权频谱与非授权频段进行载波聚合(CA，CarrierAggregation),其中授权频谱上的载波作为主服务小区(PCell，Primary Cell)，非授权频段上的载波作为辅小区(SCell，Secondary Cell)。LTE-A CA中PCell和SCell可以共站址(collocate或co-site)或者非共站址，后者例如由演进基站(eNB)和远端射频头(RRH，Remote Radio Head)分别提供PCell和SCell。PCell是用户设备(UE，User Equipment)执行随机接入过程(random access procedure)初始接入系统时的小区(cell)或者执行切换过程 (handover procedure)接入到目标基站时的小区。PCell还提供安全性(security)和非接入层(NAS，Non-Access Stratum)信令传输。SCell主要提供额外的无线资源用于数据传输。
LTE-A双连接(DC，Dual Connectivity)指为UE进行载波聚合的载波由不同的基站提供，UE能够同时或分时与两个基站进行通信，以提高小区边缘的峰值速率和吞吐量。通常基站间的连接为非理想回程链路(backhaul)，即基站间的消息往来需要一定的时延，对容量也存在一定的限制。参与LTE-ADC的基站中包括一个主基站(MeNB，Master eNB)和一个辅基站(SeNB，Secondary eNB)，主基站提供PCell，可选的，还有其它SCell；辅基站提供主辅小区(PSCell，Primary Secondary Cell)，PSCell支持物理上行控制信道(PUCCH，Physical Uplink Control Channel)，可选的，还有其它SCell。主基站为UE提供S1-移动管理实体接口(S1-MME)连接的基站，辅基站主要用于提供额外的无线资源用于数据传输。
在对终端配置授权LTE小区和非授权LTE小区进行载波聚合的情况下，终端不对非授权LTE小区进行无线链路监测。在配置终端单独使用非授权LTE小区，或配置终端对授权LTE小区和非授权LTE小区进行跨基站双连接的情况下，如果终端不对非授权LTE小区进行无线链路监测，则可能无法及时发现非授权LTE小区的无线信道由于恶化而无法向终端提供传输服务的情况，导致终端通信质量下降甚至中断，严重影响用户体验。

参见图2，为本发明实施例提供的一种无线链路监测方法的流程示意图，在本发明实施例中，所述方法包括：
S201基站竞争非授权频段的使用权。
具体的，非授权频段没有被分配给固定的使用者，多个使用者需要通过竞争的方式获取非授权频段的使用权。基站需要利用非授权频段传输数据(包括业务数据或控制信令)时，首先应该获得非授权频段信道的使用权，占用非授权频段信道一定时长，然后在占用的时长内传输数据。其中，基站竞争非授权频段信道的使用权的方法可以基于CCA(Clear ChannelAssessment，空闲信道评估，简称CCA)检测机制或ECCA(Enhanced Clear ChannelAssessment，增强的空闲信道评估，简称ECCA)检测机制。例如，基站在CCA时间内检测到非授权频段为空闲状态时，即竞争到非授权频段的使用权，占用非授权频段一定时长；或基站在CCA时间段内检测到非授权频段为忙碌状态时，触发ECCA检测流程，设置一个随机数，后续每在一个CCA时间段内检测到非授权频段为空闲状态时，随机数减1，当随机数达到0时，基站即竞争到非授权频段的使用权，占用非授权频段一定时长。其中，基站在CCA时间段检测非授权频段的状态的方法可以是：测量CCA时间内非授权频段上的接收信号功率，在接收信号功率小于预设功率阈值时，则判定非授权频段在CCA时间内为空闲状态。
S202、在当前时刻竞争到所述非授权频段的使用权后，所述基站向用户设备发送所述非授权频段的使用权的统计信息；其中，所述统计信息表示根据预设的统计方法对所述非授权频段的使用权进行统计后得到的数据。
具体的，基站竞争到非授权频段的使用权的时刻为当前时刻，例如，在CCA检测机制中，当前时刻为检测到非授权频段为空闲状态的CCA时间的结束时刻；在ECCA检测机制中，当前时刻为随机数达到0时对应的CCA时间段的结束时刻。基站在当前时刻竞争到非授权频段的使用权后，向非授权频段对应的小区内的用户设备发送非授权频段的使用权的统计信息。统计信息表示根据预设的统计方法对非授权频段的使用权进行统计后得到的数据。例如，对指定时间区间内的非授权频段的使用权的次数、时长、比例信息等进行统计得到的数据。指定时间区间可以是周期性的时间区间或非周期性的时间区间，本发明不作限制。
其中，基站向用户设备发送统计信息时，可以单独向用户设备发送统计信息，或者将统计信息携带在控制信令中发送给用户设备，例如可用指示消息中携带统计信息，可用指示消息用于表示非授权频段由忙碌状态转换为空闲状态，即非授权频段对应的非授权频段小区有不可用状态转换为可用状态。
实施本发明的实施例，基站在竞争到非授权频段的使用权时，向用户设备发送在指定的时间区间内竞争到的非授权频段的统计信息，从而在配置用户设备单独使用非授权小区或配置用户设备对授权小区和免授权小区进行跨基站双连接的情况下，解决用户设备无法及时发现免授权小区无线信道质量下降而导致终端通信质量下降甚至中断，提高用户设备的服务质量。
可选的，所述统计信息表示从起始时刻至竞争到所述非授权频段的使用权的时刻内竞争到所述非授权频段使用权的累计次数，且累计次数为约定数值范围内的循环计数值；
其中，所述起始时刻为所述基站首次参与竞争所述非授权频段的使用权的时刻或约定周期的时间区间的起始时刻。
具体的，统计信息表示从起始时刻至当前时刻内竞争到非授权频段的使用权的累计次数，即基站统计指定的时间区间内的竞争到非授权频段的使用次数，该指定的时间区间分为两种：一，基站首次参与竞争非授权频段的使用权 的时刻作为起始时刻和当前时刻组成的时间区间；二，约定周期的时间区间中的任意一个，时间区间每隔约定周期出现一次。在指定的时间区间为类型一的情况下，时间区间的持续时间可能会非常大，基站在指定的时间区间内每抢占到一次非授权频段的使用权时，计数值加1，当计数值超过预设值时，计数值清零，重新进行加1计数，次数的计数值即为累计次数，累计次数为循环计数值。如果指定的时间区间为类型二的情况下，基站在指定的时间区间内每抢占到非授权频段的使用权时，计数值加1，当计数值超过预设值时，计数值清零。在下一时间区间内，上一时间区间的计数值清零，当前时间区间内从初始值0开始计数。
所述统计信息表示从起始时刻至所述当前时刻内竞争到所述非授权频段的使用权的累计时长，且累计时长为约定数值范围内的循环计数值；
其中，所述起始时刻为所述基站首次参与所述非授权频段使用权竞争的时刻或约定周期的时间区间的起始时刻。
具体的，统计信息表示从起始时刻至当前时刻内竞争到非授权频段的使用权的累计时长，即基站统计指定的时间区间内占用非授权频段的累计时长，该指定的时间区间分为两种：一，基站首次参与竞争非授权频段的使用权的时刻作为起始时刻和当前时刻组成的时间区间；二，约定周期的时间区间中的任意一个，时间区间每隔约定周期出现一次。在指定的时间区间为类型一的情况下，时间区间的持续时间可能会非常大，在指定的时间区间内基站每竞争到非授权频段的使用权时，占用非授权频段一定的时长，将占用非授权频段的时长进行累加得到指定的时间区间内的累计时长，当累计时长超过预设值时，累计时长清零，重新统计累计时长；在指定的时间区间为类型二的情况下，基站每竞争到非授权频段的使用权时，占用非授权频段一定时长，基站统计指定的时间区间内占用非授权频段的累计时长。基站在新的时间区间内统计累计时长时，从初始值0开始统计。
需要说明的是，基站在竞争到非授权频段的使用权时，占用非授权频段预设时长，向非授权频段对应的非授权频段小区内的用户设备发送可用指示消息，可用指示消息中携带该预设时长，以使用户设备能够得到非授权频段对应的非授权频段小区可用的时间窗口，在时间窗口内传输数据。
可选的，所述统计信息表示从起始时刻至竞争到所述非授权频段的使用权的时刻内竞争到所述非授权频段的使用权的累计时长与从所述起始时刻至所述当前时刻的总时长的比值信息；
其中，所述起始时刻为所述基站首次参与竞争所述非授权频段的使用权的时刻或约定周期的时间区间的起始时刻。
具体的，统计信息表示从起始时刻至当前时刻竞争到非授权频段的使用权的累计时长与起始时刻至当前时刻的总时长的比例信息，当前时刻为竞争到所述非授权频段的使用权的时刻，即基站统计指定的时间区间内占用非授权频段的累计时长与该指定的时间区间的总时长的比值信息。指定的时间区间分为两种类型：一，基站首次参与竞争非授权频段的使用权的时刻作为起始时刻和当前时刻组成的时间区间；二，约定周期的时间区间中任意一个，时间区间每隔约定周期出现一次。在指定的时间区间为类型一的情况下，指定的时间区间为非周期性的，基站在指定的时间区间内统计占用非授权频段的累计时长，以及计算指定的时间区间的总时长，得出累计时长和总时长的比值信息；在指定的时间区间为类型二的情况下，指定的时间区间为以约定周期出现的时间周期中的任意一个，每个时间区间的总时长为固定值，基站统计指定的时间区间内占用非授权频段的累计时长，根据累计时长和总时长得出比值信息。
可选的，所述在当前时刻竞争到所述非授权频段的使用权后，所述基站向用户设备发送所述非授权频段使用权的统计信息，还包括：
所述基站向所述用户设备发送所述约定周期的时间区间标识信息。
具体的，基站在当前时刻竞争到非授权频段信道的使用权后，基站获取指定的时间区间内的非授权频段的使用权的统计信息，统计信息包括：指定时间区间内非授权频段为空闲状态的累计次数、指定时间区间内占用非授权频段的累计时长、累计时长和/或指定的时间区间的总时长的比值信息，基站向用户设备发送获取到的统计信息，统计基站还需向用户设备发送指定的时间区间的标识信息，告知用户设备统计信息是在哪个时间区间内统计的。
可以理解的是，在指定的时间区间为类型一的情况下，基站也需要向用户设备发送指定的时间区间的标识信息，用户设备根据标识信息得到基站在哪个时间区间内统计的。
可选的，所述方法还包括：
所述基站向所述用户设备发送可用指示消息，所述可用指示消息用于指示所述非授权频段对应的非授权频段小区由不可用状态转换为可用状态，所述可用指示消息中携带所述统计信息。
具体的，基站在CCA时间段内监听到非授权频段为空闲状态，在CCA时间段结束时向用户设备发送可用指示消息，可用指示消息用户表示非授权频段小区由不可用状态转换为可用状态，其中可用指示消息中携带统计信息和用于表示基站占用非授权频段的时长的占用时长。用户设备可用在于基站相同的时间区间内获取统计信息，因为基站向用户设备发送可用指示消息的过程中，用户设备可能会接收不到该指示消息，导致用户设备在指定的时间区间内统计的统计信息和基站在指定的时间区间内统计的统计信息存在偏差，用户设备比较自身统计到的统计信息和来自基站的统计信息，来校准RLM(Radio Link Monitoring，无线链路监测，简称RLM)结果。RLM结果表示用户设备和基站之间的无线链路的质量。
需要说明的是，当用户设备自身统计的统计信息和基站统计的统计信息的偏差值大于预设值时，表明用户设备和基站之间的无线链路失败，用户设备向基站发起RRC重连接，或用户设备向基站报告无线链路失败。
可选的，所述在当前时刻竞争到所述非授权频段的使用权后，所述基站向用户设备发送所述非授权频段使用权的统计信息之后，还包括：
所述基站接收所述用户设备发送的RLM结果；
所述基站根据所述RLM结果，指示所述用户设备停止使用所述非授权频段小区。
具体的，用户设备向基站发送RLM结果的方式包括事件触发和周期触发，在事件触发的情况下，基站接收到用户设备发送的RLM结果，指示用户设备停止使用非授权频段小区；如果为周期性触发的情况下，基站需要判断用户设备上报RLM结果对应的时间区间，基站获取该时间区间内的统计信息和RLM结果中的统计信息进行比较，根据比较结果决定是否指示用户设备停止使用非授权频段小区。
参见图3，为本发明实施例提供的一种无线链路监测方法的流程示意图， 在本发明实施例中，所述方法包括：
S301、用户设备接收基站发送的第一统计信息；其中，所述第一统计信息为所述基站在指定时间区间内竞争到的非授权频段的使用权的统计信息。
具体的，用户设备接收基站发送的第一统计信息，第一统计信息为基站在指定时间区间内竞争到的非授权频段的使用权的统计信息，例如：第一统计信息包括：基站在指定区间内竞争到非授权频段的使用权的的累计次数，即基站在指定时间区间内每抢占到非授权频段的使用权时，向用户设备发送可用指示消息，计数值加1，指定时间区间结束时，获取最终的计数值，该最终的计数值即为累计次数；或基站在指定时间区间内占用的非授权频段的累计时长；或累计时长与指定时间区间的总时长的比值信息。
S302、所述用户设备根据所述基站发送的可用指示信息确定所述指定时间区间内所述非授权频段的使用权的第二统计信息；其中，所述第二统计信息为所述用户设备在所述指定时间区间内统计到的所述非授权频段的使用权的统计信息。
具体的，用户设备根据基站发送的可用指示消息确定指定时间区间内非授权频段的使用权的第二统计信息。由于用户设备根据可用指示消息统计的，如果错过可用指示消息，用户设备在指定时间区间内统计的第二统计信息与第一统计信息不一致。例如，用户设备统计指定时间区间内接收到的可用指示消息的数量，将可用指示消息的数量作为用户设备统计到的非授权频段为空闲状态的累计次数，该累计次数为第二统计信息；或者，用户设备根据指定时间区间内接收到的可用指示消息携带的非授权频段的占用时长，统计在指定时间区间内占用非授权频段的累计时长，该累计时长为第二统计信息；或用户设备根据该累计时长和指定时间区间的总时长得到比例信息，该比值信息为第二统计信息。
S303、所述用户设备根据所述第一统计信息和所述第二统计信息得到RLM结果。
具体的，用户设备得到的第一统计信息为基站发送的，为准确值，用户设备根据第二统计信息进行校正，得到RLM结果。
可选的，所述指定时间区间为周期性的时间区间；或所述用户设备接入所述非授权频段对应的非授权频段小区的时刻至当前时刻组成的时间区间。
具体的，时间区间每隔一定周期出现一次，指定时间区间为周期性的时间区间中的任意一个；或指定时间区间为用户设备接入非授权频段小区的时刻至当前时刻组成的时间区间。其中，用户设备测量的时间区间和基站测量的时间区间必须保持一致。
可选的，所述RLM结果为所述第一统计信息与所述第二统计信息的差值或所述RLM结果为所述第二统计信息与所述第一统计信息的差值。
示例性的，第一统计信息和第二统计信息为累计次数，第一统计信息对应的累计次数为10次，第二统计信息对应的累计次数为8次，则RLM结果为10-8＝2次；第一统计信息和第二统计信息为累计时长，第一统计对应的累计时长为100ms，第二统计信息对应的累计时长为90ms，则RLM结果为100ms-90ms＝10ms；第一统计信息和第二统计信息为比值信息时，总时长为150ms，则第一统计信息对应的比值信息为100/150＝0.77，第二统计信息对应的比值信息为90/150＝0.6，RLM结果为0.77-0.6＝0.16。
需要说明的是，RLM结果的绝对值大于预设值时，表明用户设备错误大量的可用指示消息，用户设备与基站之间的无线链路失败，此时用户设备可以向基站上报RLM结果，基站根据RLM结果指示用户设备停止使用非授权频段小区。
可选的，本发明实施例还提供了一种无线链路监测方法，包括：用户设备确定在预设时间区间内接收到基站发送的可用指示信息的累计次数；其中，所述预设时间区间的起始时刻为所述用户设备上一次接收到所述基站发生的可用指示信息的时刻或周期性的时间区间的起始时刻或所述用户设备接入所述非授权频段对应的非授权频段小区的时刻；如果在所述预设时间区间内接收到所述接收到可用指示信息的累计次数小于预设次数，所述用户设备发起RRC连接重建立过程；和/或向基站发送无线链路失败的报告。
具体的，预设时间区间内用户设备接收到的可用指示消息的累计次数小于预设次数表明，用户设备和基站之间的链路状态恶化，无法维持正常的通信，次数用户设备可发起RRC(Radio Resource Control，无线资源控制，简称RRC)重连接和/或向基站发送无线链路失败的报告。
可选的，所述第二统计信息表示在所述指定时间区间内统计到所述非授权 频段使用权的累计次数，且累计次数为约定数值范围内的循环计数值。
具体的，指定时间区间为基站通知用户设备的时间区间，第二统计信息表示用户在指定时间区间内统计到的非授权频段的使用权的累计次数，用户设备统计累计次数的方法可以是根据基站在指定时间区间内发送的可用指示消息来确定，基站在指定时间区间内每检测到非授权频段为空闲状态时，向用户设备发送可用指示消息，因此可用指示消息的次数等于竞争到非授权频段的使用权的累计次数，累计次数为指定数值范围内的循环计数值，因为在指定时间区间的持续时间足够长的情况下，累计次数可能会超过计数器的范围，为了避免这种情况的发生，累计次数在大于预设值时归零，重新进行计数。
需要说明的是，指定时间区间可以为周期性的时间区间中的任意一个，或基站指定的非周期性的任意时间区间，例如，基站首次参与竞争非授权频段的时刻至当前时刻组成的时间区间，或用户设备首次接入非授权频段至当前时刻组成的时间区间等。
可选的，所述第二统计信息表示在所述指定时间区间内统计到的所述非授权频段的使用权的累计时间。
具体的，基站在指定时间区间内监听到非授权频段为空闲状态时，向用户设备发送可用指示消息，可用指示消息中还携带基站占用非授权频段的时长，用户设备可以根据每次接收到的可用指示消息以及携带的占用非授权频段的时长统计指定时间区间内非授权频段的使用权的累计时间。例如，指定时间区间的持续时间为100ms，用户设备接收3次可用指示消息，每次可用指示消息携带的占用非授权频段的时长为10ms，则用户设备统计指定时间区间内非授权频段的累计时长为30ms。
可选的，所述第二统计信息表示在所述指定时间区间内统计到的所述非授权频段的使用权的累计时长与从起始时刻至所述当前时刻的总时长的比值信息。
具体的，基站在指定时间区间内监听到非授权频段为空闲状态时，向用户设备发送可用指示消息，可用指示消息中还携带基站占用非授权频段的时长，用户设备可以根据每次接收到的可用指示消息以及携带的占用非授权频段的时长统计指定时间区间内非授权频段的使用权的累计时间。例如，指定时间区 间的持续时间为100ms，用户设备接收3次可用指示消息，每次可用指示消息携带的占用非授权频段的时长为10ms，则用户设备统计指定时间区间内非授权频段的累计时长为30ms，得到累计时长与指定时间区间的总时长的比值信息为30/100＝0.3。
可选的，当所述指定时间区间结束后，向所述基站报告所述RLM结果，以使所述基站根据所述RLM结果执行相应的小区控制策略。
具体的，RLM结果包括基站在指定时间区间竞争到的非授权频段的使用权的累计次数与用户设备在指定时间区间内统计到的非授权频段的使用权的累计次数的差值的绝对值；或基站在指定时间区间内竞争到的非授权频段的使用权的累计时长与用户设备在指定时间区间内统计到的非授权频段的使用权的累计时长的差值的绝对值；或设基站在指定时间区间内竞争到的非授权频段的使用权的累计时长与指定时间区间的总时长为第一比值信息；设用户设备在指定时间区间内统计到的非授权频段的使用权的累计时长与指定时间区间的总时长为第二比值信息，RLM结果为第一比值信息和第二比值信息的差值的绝对值。当指定时间区间结束后，用户设备向基站上报RLM结果，基站根据RLM结果执行相应的小区控制策略，例如，RLM结果大于预设值时，表明无线链路失败，基站指示用户设备停止使用非授权频段对应的非授权频段小区。
需要说明的是，用户设备并不限于在指定时间区间结束后向基站上报RLM结果至基站，用户设备在上报之前判断RLM结果是否大于预设值，例如累计次数的差值的绝对值大于预设值，或累计时长的差值的绝对值大于预设值或比值信息的差值的绝对值大于预设值才将RLM结果上报给基站，否则，用户设备不上报RLM结果。
示例性的参见图4，基站监听到非授权频段小区为可用状态时，向用户设备发送可用指示消息，可用指示消息中携带占用非授权频段的时长。从图4中可以看出，基站在指定时间区间内竞争到的非授权频段的使用权的次数为4次，用户设备没有接到到基站在第2次发送的可用指示消息，用户设备在指定时间区间内统计到的非授权频谱的使用权的次数为3次。
参见图5，为本发明实施例提供的一种基站的结构示意图，在本发明实施例中，所述基站包括竞争模块501和发送模块502。
