下面结合附图对本申请实施例进行说明。
图2示出了本申请实施例提供的频点的信号质量信息确定方法适用的一种可能的通信***的架构。参阅图2所示,在该通信***中包括:网络设备201(如图中的网络设备201a、网络设备201b、网络设备201c、),以及终端设备202。
所述网络设备201,负责为所述终端设备202提供无线接入有关的服务,实现无线物理层功能、资源调度和无线资源管理、服务质量(Quality of Service,QoS)管理、无线接入控制以及移动性管理(例如小区的重选和切换)功能。
每个网络设备201负责管理至少一个小区。如图所示,网络设备201a负责管理小区A和小区C,网络设备201b负责管理小区B,网络设备201c负责管理小区D。
在该通信***中,每个小区均使用相应的频点为终端设备提供接入服务。需要说明的是,不同小区使用的频点可能相同,也可能不相同。例如,小区A使用频点1,小区B使用频点2,小区C使用频点3,小区D使用频点4。此外,在该通信***中,不同小区所归属的移动通信***的类型可能相同,也可能不同。例如,小区A和小区C归属的移动通 信***为第五代(The 5
th Generation,5G)移动通信***,小区B和小区D归属的移动通信***为***(The 4
th Generation,4G)。另外,归属同一移动通信***的不同小区也可以使用不同制式的移动通信技术。例如,小区A可以使用频分双工(frequency division duplex,FDD)通信技术,小区C可以使用时分双工(time division duplex,TDD)通信技术。另外,为了提高终端设备202的数据传输速率和通信***的***容量,该通信***可以使用载波聚合(carrier aggregation,CA)技术。
所述终端设备202,为通过所述网络设备201管理的小区接入网络的设备。
所述网络设备201和所述终端设备202之间通过Uu接口连接,从而实现所述终端设备202和所述网络设备201之间的通信。
本申请实施例提供的方法适用于多频场景,即通信***中的小区使用至少两个频点。为了保证接入服务小区的终端设备202的通信质量和业务传输效率,管理该服务小区的网络设备201需要根据各个频点的信号质量信息,为所述终端设备202选择载波,以实现小区重选或切换。
还需要指出的是,如图2所示的通信***作为一个示例,并不对本申请实施例提供的方法适用的通信***构成限定,本申请实施例提供的方法可以适用于能够产生多频场景的各种通信***。
下面以小区A和小区C使用频点1,小区B和小区D使用频点2,终端设备202接入小区A(即小区A为所述终端设备202的服务小区)为例进行说明:
网络设备201a在对终端设备202进行小区重选或切换过程中,需要获得频点1和频点2的信号质量信息,从而为所述终端设备202选择信号质量信息最优的或符合设定条件的目标频点,最终将使用该目标频点的邻小区作为所述终端设备202小区切换的目标小区,或者将使用该目标频点的所述服务小区继续为所述终端设备202服务。
在传统的方法中,网络设备201a需要通过终端设备202进行邻小区测量以获得频点1和频点2的信号质量信息,具体过程包括:
网络设备201a向终端设备202发送测量配置信息,其中,所述测量配置信息中包含待测量频点,待测量的小区列表,需要测量的信号质量参数,报告方式等内容。
可选的,所述测量配置信息可以携带在RRC连接重配置(RRC connection reconfiguration)消息中。待测量的频点中可以为频点1,或者频点2,或者频点1和频点2。当待测量的频点中包含频点2时,所述测量配置信息还可以包含测量gap配置信息。
终端设备202在接收到测量配置信息后,可以根据测量配置信息中包含的内容进行邻小区测量。例如,当测量配置信息中包含频点1(同频)时,所述终端设备202需要根据所述测量配置信息中的内容进行同频测量;当测量配置信息中包含频点2(异频)时,所述终端设备202需要根据所述测量配置信息中的内容进行异频测量或异***测量。
当所述终端设备202完成所有测量后,获得频点1和/或频点2的信号质量信息,然后向所述网络设备201a发送测量报告,其中,所述测量报告中包含获得的频点1和/或频点2的信号质量信息。
所述网络设备201a根据获得的频点1和/或频点2的信号质量信息,为所述终端设备202选择目标频点,进而在所述目标频点对应的载波中选择目标载波,进而完成小区重选或切换。
需要说明的是,当所述终端设备202为CA用户时,所述网络设备为所述终端设备选 择多个目标载波。其中,所述多个目标载波可以是同一个目标频点对应的,也可以是不同的目标频点对应的,本申请对此不作限定。
众所周知地,终端设备202在进行同频测量时不需要切换工作频点,那么终端设备202可以在进行业务传输的同时进行同频测量,所以,终端设备202执行同频测量不需要暂停业务传输,不会影响终端设备202的业务传输,同频测量的过程也不会出现时间上的延误。但是终端设备202在进行异频测量或异***测量时,需要在测量gap内暂停业务传输,另外,测量每个频点消耗的时间(一般为几百ms)远远大于测量gap(一般为6ms)的时间,因此,终端设备202需要多个测量gap完成异频测量或异***测量,这就需要多次中断终端设备202的业务传输。另外,由于测量时间较长,进一步延长了网络设备202为终端设备选择载波的时间,影响了载波选择的增益。
为了保证终端设备的业务吞吐率,缩短网络设备确定异频的信号质量信息的时间,本申请实施例提供了一种频点的信号质量信息确定方法。该方法可以应用于具有多频场景的通信***中,例如图2所示的通信***。参阅图3所示,该方法的流程包括:
S301:网络设备获取终端设备测量的第一频点的信号质量信息,所述第一频点为所述终端设备接入的服务小区使用的频点。
其中,所述第一频点的信号质量信息为该终端设备通过同频测量得到的。其中,所述第一频点的信号质量信息中包含第一邻小区的信号质量参数。所述第一邻小区为使用所述第一频点的、所述服务小区的邻小区,又称为同频邻小区。所述第一邻小区的数量可以为至少一个。
可选的,所述网络设备可以但不限于通过以下方式,获取终端设备测量的所述第一频点的信号质量信息:
方式一:所述网络设备可以向所述终端设备发送测量配置信息,通知所述终端设备进行同频测量。其中,所述测量配置信息中可以包含以下信息:待测量的频点(为所述第一频点),待测量的小区列表(所述第一邻小区列表)、需要测量的信号质量参数,报告方式等。
方式二:所述终端设备可以自行进行同频测量并将测量得到的所述第一频点的信号质量信息上报给所述网络设备。
S302:所述网络设备根据所述第一频点的信号质量信息、存储的第一映射关系,确定第二频点的信号质量信息,其中,所述第二频点与所述第一频点不相同,所述第一映射关系为所述第一频点的信号质量信息与所述第二频点的信号质量信息之间的映射关系。
可选的,当通信***中存在多个第二频点时,相应的所述第一映射关系的数量也为多个,即每个第二频点对应一个第一映射关系。任一个第二频点对应的第一映射关系用于确定该第二频点的信号质量信息。
可选的,每个第二频点对应的第一映射关系是对所述第一频点的信号质量信息样本数据、该第二频点的信号质量信息样本数据进行建模后得到的。
其中,所述第一频点的信号质量信息样本数据中包含:多次通过接入所述服务小区的多个终端设备测量的所述第一频点的信号质量信息。每个终端设备测量的所述第一频点的信号质量信息中包含第一邻小区的信号质量参数。
第二频点的信号质量信息样本数据中包含:多次通过接入所述服务小区的多个终端设备测量的所述第二频点的信号质量信息。每个终端设备测量的所述第二频点的信号质量信 息中包含第二邻小区的信号质量参数。所述第二邻小区为使用所述第二频点、所述服务小区的邻小区,又可以称为异频邻小区。所述第二邻小区的数量为至少一个。
通过以上步骤,所述网络设备可以根据从终端设备获取的该终端设备进行同频测量得到的同频(即第一频点)的信号质量信息,快速地得到异频(即第二频点)的信号质量信息。
在S302之后,所述网络设备可以根据获得的所述第一频点的信号质量信息和确定的所述第二频点的信号质量信息,为所述终端设备选择信号质量高的目标频点,然后将所述目标频点对应的载波作为所述终端设备的目标载波,并将使用该目标载波的小区作为所述终端设备小区重选或切换的目标小区,从而可以保证所述终端设备切换到所述目标小区后所述终端设备的信号传输质量。
可选的,在本申请实施例中,还可以通过以下步骤,确定所述服务小区的频谱效率:
所述网络设备获取所述第一邻小区的负载信息;
所述网络设备根据所述第一频点的信号质量信息、所述第一邻小区的负载信息,以及存储的第二映射关系,确定所述服务小区的频谱效率,其中,所述第二映射关系为所述第一频点的信号质量信息、所述第一邻小区的负载信息二者与所述服务小区的频谱效率之间的映射关系。
所述第一邻小区的负载信息是所述网络设备从管理所述第一邻小区的网络设备中获取的。
与所述第一映射关系类似的,所述第二频点与所述第二映射关系也是一一对应的,即当通信***中存在多个第二频点时,每个第二频点对应一个第二映射关系。
可选的,每个第二频点对应的第二映射关系是对所述第一频点的信号质量信息样本数据、所述第一邻小区的负载信息样本数据,以及所述服务小区的频谱效率样本数据进行建模后得到的。
其中,所述第一邻小区的负载信息样本数据中包含:每次接入所述服务小区的多个终端设备测量所述第一频点的信号质量信息时所述第一邻小区的负载信息。
所述服务小区的频谱效率样本数据中包含:每次接入所述服务小区的多个终端设备测量所述第一频点的信号质量信息时所述服务小区的频谱效率。
通过以上步骤,所述网络设备还可以根据获取的所述第一邻小区的负载信息,快速地得到服务小区的频谱效率。
这样,所述网络设备在为所述终端设备选择目标频点以及目标载波(即目标小区)时,还可以综合所述服务小区的频谱效率这一因素,使得所述终端设备在切换到所述目标小区后,不仅可以保证终端设备的信号传输质量,还可以保证所述终端设备的信号传输效率。
可选的,在本申请实施例中,还可以通过以下步骤,确定所述第二邻小区频谱效率:
所述网络设备获取所述第二邻小区的负载信息;
所述网络设备根据所述第一频点的信号质量信息、所述第二邻小区的负载信息,以及存储的第三映射关系,确定所述第二邻小区的频谱效率,其中,所述第三映射关系为所述第一频点的信号质量信息、所述第二邻小区的负载信息二者与所述第二邻小区的频谱效率之间的映射关系。
所述第二邻小区的负载信息是所述网络设备从管理所述第二邻小区的网络设备中获取的。
与所述第一映射关系、第二映射关系类似的,所述第二频点与所述第三映射关系也是一一对应的,即当通信***中存在多个第二频点时,每个第二频点对应一个第三映射关系。
可选的,每个第二频点对应的第三映射关系是对所述第一频点的信号质量信息样本数据、所述第二邻小区的负载信息样本数据,以及所述第二邻小区的频谱效率样本数据进行建模后得到的。
其中,所述第二邻小区的负载信息样本数据中包含:每次接入所述服务小区的多个终端设备测量所述第二频点的信号质量信息时所述第二邻小区的负载信息。
所述第二邻小区的频谱效率样本数据中包含:每次接入所述服务小区的多个终端设备测量所述第二频点的信号质量信息时所述第二邻小区的频谱效率。
通过以上步骤,所述网络设备还可以根据获取的所述第二邻小区的负载信息,快速地得到第二邻小区的频谱效率。
这样,所述网络设备在为所述终端设备选择目标频点以及目标载波(即目标小区)时,还可以综合所述第二邻小区的频谱效率这一因素,使得所述终端设备在切换到所述目标小区后,不仅可以保证终端设备的信号传输质量,还可以保证所述终端设备的信号传输效率。
需要说明的是,在本申请实施例中,当所述终端设备为CA用户时,所述网络设备可以根据得到和确定的各项因素,为所述终端设备选择目标载波组合。
采用本申请实施例提供的上述方法,终端设备无需执行异频测量和异***测量,只需要执行同频测量并将同频的信号质量信息上报给网络设备,网络设备即可确定异频的信号质量信息,这样,网络设备可以通过同频和异频的信号质量信息,为所述终端设备选择载波(即在小区重选或切换中为所述终端设备选择目标小区)。显然,由于终端设备无需执行异频测量和异***测量,因此,该方法可以在保证载波选择的增益的同时,还可以保证终端设备的业务连续性和业务吞吐率,以及避免异频测量和异***测量的开销。另外,由于终端设备执行同频测量的时间远小于执行异频测量和异***测量的时间,因此,该方法还可以缩短网络设备确定异频的信号质量信息的时间。
另外,在该方案中所述网络设备可以快速地得到第一频点的信号质量信息、第二频点的信号质量信息、服务小区的频谱效率、第二邻小区的频谱效率,并综合考虑以上因素为所述终端设备选择目标小区,这样,在所述终端设备在切换到所述目标小区后,不仅可以保证终端设备的信号传输质量,还可以保证所述终端设备的信号传输效率。
需要说明的是,在上述实施例中,上述第一映射关系、第二映射关系以及第三映射关系均可以是计算设备采用机器学习技术,根据相应的样本数据进行建模得到的。所述计算设备可以是网络设备,也可以是服务器、核心网设备等其他设备。当所述计算设备不是网络设备时,所述计算设备在建模得到上述映射关系后,还可以将该映射关系发送给所述网络设备。
下面以所述计算设备为所述网络设备为例,对所述网络设备对每种映射关系的维护流程进行详细说明。
网络设备对任一个第二频点对应的第一映射关系进行维护的步骤包括:
A1:所述网络设备采集多条第一样本数据。
在本步骤中,所述网络设备多次通知接入所述网络设备管理的服务小区的多个终端设备进行同频测量,以及异频测量或异***测量;然后接收所述多个终端设备通过同频测量测量到的第一频点的信号质量信息,以及接收所述多个终端设备通过异频测量或异***测 量测量到的第二频点的信号质量信息。
其中,一条第一样本数据中包含所述网络设备同一次通知终端设备进行同频测量得到的第一频点的信号质量信息,以及通知终端设备进行异频测量或异***测量得到的第二频点的信号质量信息。
一种示例,在多次第一样本数据采集阶段,所述网络设备每次通知进行邻小区测量的终端设备可以相同,也可以不同,本申请实施例对此不作限定。
一种可能的实现方式中,在任意一次第一样本数据采集时,所述网络设备通知进行同频测量的终端设备和进行异频测量或异***测量的终端设备可以相同,也可以不同,本申请实施例内对此不作限定。

A3:所述网络设备对所述第一映射关系的准确性进行监控,当所述第一映射关系的准确性较低时,所述网络设备停止使用所述第一映射关系,并可以通过重复A1和A2步骤,或者重复A2步骤,更新所述第一映射关系。
可选的,所述网络设备可以但不限于以下方式对所述第一映射关系的准确性进行监控。
方式一:所述网络设备监控小区配置成功率,当所述配置成功率低于设定成功率阈值时,所述网络设备确定所述第一映射关系的准确性较低。
所述网络设备在每次使用所述第一映射关系确定所述第二频点的信号质量信息,并基于所述第二频点的信号质量信息为终端设备选择目标小区之后,所述网络设备更新所述小区配置成功率。
其中,该小区配置成功率=成功接入所述网络设备为其确定的目标小区的终端设备的数量/所述网络设备为其确定的目标小区的终端设备的总数量。
方式二:所述网络设备周期性的对所述第一映射关系进行测试。
在本方式中,所述网络设备可以通知接入所述服务小区的终端设备进行同频测量,以及异频测量或异***测量,得到第一频点的信号质量信息、第二频点的信号质量信息。然后,所述网络设备将得到的所述第一频点的信号质量信息、所述第二频点的信号质量信息作为测试数据,所述网络设备根据测试数据中所述第一频点的信号质量信息和所述第一映射关系,计算得到第二频点的信号质量信息。最后,所述网络设备判断计算得到的所述第二频点的信号质量信息与测试数据中的所述第二频点的信号质量信息差值,当该差值小于设定差值阈值时,表示所述第一映射关系的准确性较高;当该差值大于或等于该设定差值阈值时,表示所述第一映射关系的准确性较低。
通过上述步骤A3,所述网络设备可以保证所述第一映射关系的准确性,从而在使用所 述第一映射关系计算第二频点的信号质量信息时,可以降低计算得到的所述第二频点的信号质量信息与实际的所述第二频点的信号质量信息之间的误差。
网络设备对任一个第二频点对应的第二映射关系进行维护的步骤包括:
B1:所述网络设备采集多条第二样本数据。
在本步骤中,所述网络设备多次通知接入所述网络设备管理的服务小区的多个终端设备进行同频测量;然后接收所述多个终端设备通过同频测量测量到的第一频点的信号质量信息。所述网络设备在每次通知终端设备进行同频测量时,从管理第一邻小区的网络设备中获取所述第一邻小区的负载信息,以及接收接入所述服务小区的终端设备上报获得服务小区的频谱效率。所述第一邻小区为使用所述第一频点的、所述服务小区的邻小区,又称为同频邻小区。
