Description

通信方法、设备及存储介质 技术领域
本发明涉及电子技术领域，尤其涉及一种通信方法、设备及存储介质。
背景技术
由于多层无线网络具有易于扩展及容易故障隔离等特点，因此，多层星形无线网络得到广泛应用。例如，一个控制端控制多个警用无人机以对某些场所(如车站)进行巡逻，一个控制端控制多个农用无人机以对农作物进行施肥，一个控制端控制多个监控设备以对某些区域(如商场)进行监控等等。
其中，以双层星形无线网络为例，该双层星形无线网络的网络拓扑结构如图1a所示。该双层星形无线网络可以包括一个高层节点及多个通信系统，图1a中以两个通信系统为例，分别为第一通信系统和第二通信系统。其中，高层节点用于控制各个通信系统，如为各个通信系统分配任务。每个通信系统可以包括一个或多个中间层节点，以及位于中间层节点下的一个或多个底层节点，所有的通信系统使用同一个工作频段，每个通信系统的最高层的中间层节点从该工作频段中获取一个频点作为对应通信系统内的工作频点。在严格的时分双工(Time Division Duplexing，TDD)系统下，上下行子帧使用相同频点，这个频点就定义工作频点；如果上行子帧使用跳频，那么只有下行频点定义为工作频点。通常通过测量子帧的方式来确定各个通信系统的工作频点，例如，图1a中的底层节点在测量子帧对多个频点进行扫描得到多个频点对应的干扰信息，并将扫描得到干扰信息上报给中间层节点，由中间层节点根据接收到的干扰信息及自身扫描得到的干扰信息确定底层节点和/或中间层节点的工作频点。实践中发现，存在测量子帧的位置设置不合理的问题，导致各个通信系统之间的无线干扰比较大，并降低了通信质量。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
为了更好理解本发明实施例提供的一种通信方法及设备，下面先对该通信方法应用的系统架构进行描述。
该通信方法应用的系统架构可以为多层无线网络。例如，该多层无线网络可以为多层星形无线网络，在其他实施方式中，多层无线网络也可以是其他合适的含有多个层级的无线网络。在本实施例中，以多层星形无线网络为例。进一步地，多层星形无线网络可以是双层星形无线网络或三层星形无线网络等。其中，该多层星形无线网络可包括至少两个通信系统，即至少包括 第一通信系统和第二通信系统。其中，该多层星形无线网络中各个通信系统中包括至少一个通信设备，各个通信设备可以被视为各个节点，用于在测量子帧扫描得到干扰信息。其中，通信系统中的最上层的中间层节点可根据通信系统中各个节点扫描得到的干扰信息来确定工作频点。在本实施例中，定义最上层的中间层节点为第一中间层节点。
以该多层星形无线网络为双层星形无线网络为例，如图1a所示，该双层星形无线网络包括第一通信系统和第二通信系统，该双层星形无线网络的每个通信系统均包括一个中间层节点，通信系统该中间层节点是与高层节点直接连接的节点。如图1a所示，第一通信系统的各个节点用于在测量子帧扫描得到干扰信息。其中，第一通信系统的各个底层节点在测量子帧结束后，将扫描得到的干扰信息发送至第一通信系统的中间层节点。第一通信系统的中间层节点根据自身扫描到的干扰信息和接收的由底层节点上报的干扰信息确定工作频点。第一通信系统的中间层节点确定工作频点之后，将工作频点下发至第一通信系统的各个底层节点。第二通信系统确定工作频点的原理与第一通信系统确定工作频点的原理相同，在此不赘述。
进一步地，以该多层星形无线网络为三层星形无线网络为例，如图1b所示，该三层星形无线网络包括第一通信系统和第二通信系统，每个通信系统包括一个高层节点、两层中间层节点以及一层底层节点。其中，两层中间层节点包括第一中间层节点和第二中间层节点，其中，第一中间层节点用于与高层节点直接连接，第二中间层节点用于与底层节点直接连接。
具体地，如图1b所示，第一通信系统的各个节点用于在测量子帧扫描得到干扰信息。其中，第一通信系统的各个底层节点在测量子帧结束后，将扫描得到的干扰信息发送至第一通信系统的第二中间层节点。第二中间层节点在测量子帧结束后，将自身扫描得到的干扰信息和接收的干扰信息发送至第一中间层节点。第一中间层节点根据自身扫描到的干扰信息和接收的由第二中间层节点上报的干扰信息确定工作频点。第一通信系统的中间层节点确定工作频点之后，将工作频点下发至第一通信系统的各个节点。第二通信系统确定工作频点的原理与第一通信系统确定工作频点的原理相同，在此不赘述。
本申请实施例的多层星形无线网络中包括通信设备，该通信设备用于执行本申请的通信方法。该通信设备可以是多层星形无线网络中第一通信系统 中的任意一个节点。第一通信系统可以是多层星形无线网络中的任意一个通信系统。例如，该通信设备可以为图1a或图1b所示的第一通信系统的任一中间层节点或底层节点。其中，多层星形无线网络中的中间层节点可以为控制设备，如遥控器；多层星形无线网络中的底层节点可以为该移动机器人，所述移动机器人可以是无人飞行器、无人地面机器人、无人船、无人飞行器、无人地面机器人、无人船等等。
请参见图2，图2是本发明实施例提供的一种通信方法的流程示意图，该方法可以应用于上述通信设备，如图2所示，该通信方法可以包括如下步骤。
S201、通信设备获取第一通信系统的标识。
本发明实施例中，通信设备可以获取第一通信系统的标识，该标识可以是指第一通信系统的编号或名称等。该标识可以是由数字、汉字、字母及符号中的一种或多种组成的。其中，该多层星形无线网络中各个通信系统的标识不相同。
S202、该通信设备根据该第一通信系统的标识确定该第一通信系统的第一测量子帧的位置。
其中，在每个配置时间间隔之内，每个通信系统被配置至少一个测量子帧，根据多个通信系统中不同通信系统的标识，该多个通信系统中的不同通信系统被配置不同位置的测量子帧。其中，一个配置时间间隔可以是无线帧的时长的整数倍，例如，一个配置时间间隔可以是一个无线帧的时长或两个无线帧的时长等，本申请实施例不做限定。当然，一个配置时间间隔也可以不是无线帧的时长的整数倍，本申请实施例不做限定。其中，一个无线帧可以由多个子帧组成。通常一个无线帧包括10个子帧，一个子帧为1ms(毫秒)。其中，一个无线帧也可包括10个以上或10个以下的子帧，一个子帧也可以大于1ms或小于1ms，本申请实施例不做限定。
可选的，第一通信系统的第一测量子帧为第一个配置时间间隔内第一通信系统的测量子帧。
举例来说，多层星形无线网络中具有两个通信系统，分别为第一通信系统和第二通信系统。配置时间间隔为一个无线帧。第一通信系统在第一无线帧中被配置了一个或多个测量子帧，第二通信系统在第一无线帧中也被配置 了一个或多个测量子帧。第一通信系统在第二无线帧中被配置了一个或多个测量子帧，第二通信系统在第二无线帧中也被配置了一个或多个测量子帧。依次类推，第一通信系统和第二通信系统在每个无线帧中都被配置了一个或多个测量子帧。在第一无线帧中第一通信系统的测量子帧的位置和第二通信系统的测量子帧的位置不相同。在第二无线帧中第一通信系统的测量子帧的位置和第二通信系统的测量子帧的位置不相同，依次类推。其中，第一通信系统的第一测量子帧为第一无线帧中包括的测量子帧。
本申请实施例中，多层星形无线网络根据通信系统的标识来配置在第一个配置时间间隔内该通信系统的测量子帧。多层星形无线网络根据不同的通信系统的标识在第一个配置时间间隔内为不同的通信系统配置不同位置的测量子帧。因此，根据第一通信系统的标识就可确定第一通信系统在第一个配置时间间隔内的测量子帧的位置，即根据第一通信系统的标识就可确定第一通信系统的第一测量子帧的位置。多层星形无线可根据第一通信系统的第一测量子帧的位置和配置时间间隔配置后续的第一通信系统的测量子帧。
举例来说，如图3所示，一个配置时间间隔为一个无线帧的时长。第一无线帧为第一个配置时间间隔，第二无线帧为第二个配置时间间隔。依次类推，第二无线帧之后的无线帧未在图3中示出，图3以第一无线帧和第二无线帧为例。多层星形无线网络根据各个通信系统的标识为各个通信系统在各个无线帧内配置一个或多个测量子帧，图3以在一个无线帧内每个通信系统被配置一个测量子帧为例。如图3所示，多层星形无线网络根据第一通信系统的标识，配置第一无线帧中的子帧2为第一通信系统的第一测量子帧。多层星形无线网络根据第二通信系统的标识配置第一无线帧中的子帧3为第二通信系统的第一测量子帧。多层星形无线网络根据第一通信系统的第一测量子帧的位置和配置时间间隔，配置第二无线帧中子帧2为第一通信系统的测量子帧。多层星形无线网络根据第二通信系统的第一测量子帧的位置和配置时间间隔，配置第二无线帧中子帧3为第二通信系统的测量子帧。因此，根据第一通信系统的标识可确定第一通信系统的第一测量子帧的位置为第一无线帧中的子帧2。进一步地，根据第二通信系统的标识可确定第二通信系统的第一测量子帧的位置为第一无线帧中的子帧3。
若多层星形无线网络中的每个通信系统的测量子帧的位置相同，则各个 通信系统在测量子帧内都处于接收信号的状态，没有通信系统处于发送信号状态，这将导致每个通信系统检测不到多层星形无线网络中其他通信系统的干扰信息，进而导致多个通信系统确定的工作频点可能相同或相邻。多个通信系统的工作频点相同或相邻会导致各个通信系统之间形成干扰，严重时导致多个通信系统无法正常工作。在图2所描述的方法中，根据不同通信系统的标识，不同通信系统被配置不同位置的测量子帧。因此，第一通信系统的通信设备可根据第一通信系统的标识确定第一通信系统的第一测量子帧的位置。由于第一通信系统的通信设备确定的第一通信系统的第一测量子帧的位置与其他通信系统确定的测量子帧的位置不相同，进而可使第一通信系统根据在第一测量子帧扫描得到的干扰信息确定的工作频点与其他通信系统确定的工作频点不相同。因此，通过实施图2所描述的方法，有利于降低各个通信系统之间的无线干扰。
作为一种可选的实施方式，多层星形无线网络中的各个通信系统的包括测量子帧的无线帧的帧结构不同。
举例来说，以配置时间间隔为一个无线帧以及各个通信系统在一个配置时间间隔内均包括一个测量子帧为例。第一通信系统及第二通信系统的无线帧的帧结构可以如图3所示。在图3中，D表示无线帧中的下行子帧，U表示上行子帧，M表示测量子帧；下行子帧为中间层节点向底层节点发送数据的子帧，上行子帧为底层节点向中间层节点发送数据的子帧。如图3所示，在第一无线帧中，第一通信系统的测量子帧的位置为第一无线帧中子帧2所在的位置，第二通信系统的测量子帧的位置为第一无线帧中子帧3所在的位置。同样，在第二无线帧中，该第一通信系统的测量子帧的位置为第二无线帧中子帧2所在的位置，第二通信系统的测量子帧的位置为第二无线帧中子帧3所在的位置。如图3所示，图3中第一通信系统的第一无线帧的帧结构与第二通信系统的第一无线帧的帧结构不同，图3中第一通信系统的第二无线帧的帧结构与第二通信系统的第二无线帧的帧结构不同。
在一个实施例中，多层星形无线网络中的各个通信系统的包括测量子帧的无线帧的帧结构不同时，在一个配置时间间隔内，不同的通信系统可具有不同数量的测量子帧。例如，如图4所示，配置时间间隔为一个无线帧。在第一无线帧和第二无线帧内，第一通信系统具有两个测量子帧，第二通信系 统具有一个测量子帧。
在一个实施例中，多层星形无线网络中的各个通信系统的包括测量子帧的无线帧的帧结构不同时，相邻的两个配置时间间隔可以相同或不同。例如，第一个配置时间间隔可以为一个无线帧的时长，第二个配置时间间隔可以为两个无线帧的总时长，第三个配置时间间隔可以为三个无线帧的总时长。
作为一种可选的实施方式，在一个配置时间间隔内，以目标时间为周期，多层星形无线网络中的各个通信系统被轮流配置至少一个测量子帧，其中，该配置时间间隔为该目标时间与该多层星形无线网络中通信系统数量的乘积。例如，该多层星形无线网络中包括2个通信系统，目标时间为1个无线帧的时长，则该配置时间间隔为2个无线帧的时长。可以理解，在其他实施例中，每个通信系统完成一次测量可能需要多个无线帧，此时目标时间为多个无线帧的时长，例如目标时间为3个无线帧的时长，此时配置时间间隔为3个无线帧的时长与该多层星形无线网络中通信系统数量的乘积。
其中，各个通信系统被轮流配置测量子帧的轮流配置次序可以是根据通信系统的标识设置的。例如，在一个配置时间间隔内，可以先为第一通信系统配置测量子帧，再为第二通信系统配置测量子帧。
举例来说，以多层星形无线网络中包括2个通信系统，目标时间为一个无线帧的时长，配置时间间隔为两个无线帧的时长以及各个通信系统在一个配置时间间隔内均包括一个测量子帧为例。如图5所示，第一个配置时间间隔为第一无线帧+第二无线帧。在第一个配置时间间隔内，先配置第一无线帧的子帧2为第一通信系统的测量子帧，再配置第二无线帧的子帧2为第二通信系统的测量子帧。同理，在第二个配置时间间隔内，先配置第三无线帧的子帧2为第一通信系统的测量子帧，再配置第四无线帧的子帧2为第二通信系统的测量子帧。因此，第一通信系统和第二通信系统在一个配置时间间隔内，是以一个无线帧的时长为周期轮流被配置测量子帧的。
在一个实施例中，在一个配置时间间隔内，以目标时间为周期，多个通信系统中的各个通信系统被轮流配置至少一个测量子帧，该配置时间间隔为目标时间与多个通信系统中通信系统数量的乘积，该各个通信系统包括测量子帧的无线帧的帧结构相同。如图5所示，第一通信系统的第一无线帧的结构与第二通信系统的第二无线帧结构相同，第一通信系统的第三无线帧的结 构与第二通信系统的第四无线帧结构相同。
在一个实施例中，在一个配置时间间隔内，以目标时间为周期多个通信系统中的各个通信系统被轮流配置至少一个测量子帧，该配置时间间隔为目标时间与多个通信系统中通信系统数量的乘积，在一个配置时间间隔内，不同的通信系统可具有不同数量的测量子帧。
在一个实施例中，在一个配置时间间隔内，以目标时间为周期，多个通信系统中的各个通信系统被轮流配置至少一个测量子帧，该配置时间间隔为目标时间与多个通信系统中通信系统数量的乘积，该多个通信系统包括第二通信系统，在一个该配置时间间隔之内，如果第一通信系统的测量子帧的位置在第二通信系统的测量子帧的位置之前，则该第二通信系统的测量子帧的位置在该第一通信系统确定工作频点之后。
例如，如图5所示，在一个该配置时间间隔之内，第一通信系统的测量子帧的位置在第二通信系统的测量子帧的位置之前。如图6所示，假设配置时间间隔为两个无线帧的时长，在一个配置时间间隔内，第一通信系统确定工作频点的时间为t1，第二通信系统的测量子帧的位置为t2，t1在t2之前，即第二通信系统的测量子帧的位置在第一测量子帧确定工作频点之后。其中，由于第一通信系统的中间层节点获取到干扰信息后，需要一定的时间来计算工作频点，因此，第一通信系统的测量子帧的位置与在第一通信系统确定工作频点之间具有一定的间隔。同理，在下一个配置时间间隔之内，第一通信系统的测量子帧的位置也在第二通信系统的测量子帧的位置之前，第二通信系统的测量子帧的位置也在该第一通信系统确定工作频点之后。
在一个实施例中，该多个通信系统包括第二通信系统，在一个该配置时间间隔之内，如果第一通信系统的测量子帧的位置在第二通信系统的测量子帧的位置之后，则该第一通信系统的测量子帧的位置在该第二通信系统确定工作频点之后。
例如，如图7所示，在图7中，以目标时间(即一个无线帧的时长)为周期第一通信系统和第二通信系统轮流被配置测量子帧。在第一无线帧，子帧2被配置为第二通信系统的测量子帧，在第二无线帧，子帧2被配置为第一通信系统的测量子帧。每个配置时间间隔(即两个无线帧的时长)第一通信系统具有一个测量子帧，每个配置时间间隔第二通信系统具有一个测量子 帧。如图7所示，在一个配置时间间隔之内，第一通信系统的测量子帧的位置在第二通信系统的测量子帧的位置之后。如图8所示，假设第一通信系统确定的测量子帧的位置为t4，第二通信系统的确定工作频点的时间为t3，其中，t4在t3之后，即该第一通信系统的测量子帧的位置在该第二通信系统确定工作频点之后。其中，由于第二通信系统的中层获取到干扰信息后，需要一定的时间来确定工作频点，因此，第二通信系统的测量子帧的位置与第二通信系统确定工作频点之间具有一定间隔。
在一个实施例中，该通信设备为所述第一通信系统的底层节点或所述第一通信系统中除第一中间层节点之外的中间层节点，该通信设备在该第一测量子帧针对多个频点扫描得到该多个频点对应的干扰信息，该通信设备将该多个频点对应的干扰信息发送到该第一通信系统的第一中间层节点，该多个频点对应的干扰信息用于该第一通信系统的第一中间层节点确定工作频点，该通信设备接收该第一通信系统的第一中间层节点反馈的该工作频点。
若该多层星形无线网络为双层星形无线网络，则该通信设备可为该第一通信系统的底层节点。例如，该通信设备可以为图1a所示的双层星形无线网络中第一通信系统的任一底层节点，该第一通信系统的第一中间层节点即为第一通信系统的中间层节点。第一通信系统的各个底层节点可以在该第一测量子帧针对多个频点扫描得到该多个频点对应的干扰信息，并将干扰信息上报至第一通信系统的中间层节点；由中间层节点根据接收到的干扰信息及自身扫描得到的干扰信息确定工作频点，并由中间层节点将工作频点反馈给第一通信系统的各个底层节点，第一通信系统的各个底层节点和中间层节点可以以该工作频点进行收发信息。
若该多层星形无线网络为三层星形无线网络或三层以上的星形无线网络，则该通信设备可以为该第一通信系统的底层节点或该第一通信系统中除第一中间层节点之外的中间层节点。例如，该通信设备可以为图1b所示的三层星形无线网络中第一通信系统的任一底层节点，该第一通信系统的第一中间层节点即为第一通信系统的第一中间层节点。第一通信系统的各个底层节点可以在该第一测量子帧针对多个频点扫描得到该多个频点对应的干扰信息，并将干扰信息上报至第一通信系统的第二中间层节点。由第一通信系统的第二中间层节点将自身扫描得到干扰信息及接收到的干扰信息上报至第一 通信系统的第一中间层节点，并由第一通信系统的第一中间层节点根据接收到的干扰信息及自身扫描得到的干扰信息确定工作频点。进一步，由第一通信系统的第一中间层节点将工作频点下发至第一通信系统的各个第二中间层节点，第一通信系统的各个底层节点接收由第一通信系统的各个第二中间层节点转发的该工作频点。
再例如，该通信设备可以为图1b所示的该第一通信系统中除第一中间层节点之外的中间层节点，即该通信设备可以为该第一通信系统中的第二中间层节点中的任一中间层节点，该第一通信系统的第一中间层节点即为第一通信系统的第一中间层节点。第一通信系统的各个第二中间层节点可以在该第一测量子帧针对多个频点扫描得到该多个频点对应的干扰信息，并将自身扫描得到干扰信息及各个底层节点扫描得到的干扰信息上报给第一通信系统的第一中间层节点。由第一通信系统的第一中间层节点根据自身扫描得到干扰信息及接收到的干扰信息确定工作频点，该第一通信系统中的各个第二中间层节点可以接收第一通信系统的第一中间层节点发送的工作频点。该第一通信系统中的各个第二中间层节点还可以将该工作频点转发至第一通信系统的各个底层节点，该第一通信系统的第一中间层节点、各个第二中间层节点、各个底层节点可以以该工作频点进行收发信息。
在另一个实施例中，该通信设备为该第一通信系统的第一中间层节点，该通信设备接收该第一通信系统的多个底层节点和/或该第一通信系统中除第一中间层节点之外的中间层节点发送的多个频点对应的干扰信息，该多个频点对应的干扰信息是该第一通信系统的多个底层节点和/或所述第一通信系统中除第一中间层节点之外的中间层节点在该第一测量子帧针对多个频点扫描得到的，该通信设备根据接收到的干扰信息确定每个频点对应的平均干扰值，该通信设备将平均干扰值最小的频点作为工作频点，该通信设备将该工作频点反馈给该第一通信系统的多个底层节点和/或所述第一通信系统中除第一中间层节点之外的中间层节点。具体地，每个频点对应的干扰值可以是平均干扰值，也可以是通过诸如计算方差等其他合适的算法得到的干扰值。
例如，该通信设备可以为图1a所示的双层星形无线网络中第一通信系统的中间层节点，该多个频点为f 0～f M，M为频点个数，该干扰信息可以为包括每个频点对应的干扰值。通信设备可以接收各个底层节点发送的干扰信息， 每个底层节点发送的干扰信息均包括在第一测量子帧针对频点f 0～f M中各个频点测量得到的每个频点对应的干扰值，中间层节点根据接收到干扰信息及自身扫描得到的干扰信息计算每个频点对应的平均干扰值，将该平均干扰值最小的频点作为工作频点，并返回给各个底层节点。其中，通信设备可以采用公式(1)计算工作频点。
freq_working＝f iwhith min(average_ipsd(f i))    (1)
其中，average_ipsd(f i)表示所有的底层节点在第一测量子帧针对f i频点上测量得干扰值的平均值，f i表示第i个频点，i＝1，2…，M，freq_working表示第一通信系统的工作频点。
再例如，该通信设备可以为图1b所示的多层星形无线网络中第一通信系统的第一中间层节点，第一通信系统的第一中间层节点可接收第一通信系统的各个第二中间层节点发送的干扰信息，该干扰信息包括第一通信系统的各个第二中间层节点自身扫描得到的干扰信息及第一通信系统的各个底层节点扫描得到的干扰信息。第一通信系统的第一中间层节点可以根据接收到的干扰信息及第一通信系统的第一中间层节点自身扫描得到的干扰信息确定工作频点。第一通信系统的第一中间层节点可以将该工作频点发送至第一通信系统的第二中间层节点，由第一通信系统的第二中间层节点将该工作频点转发至第一通信系统的各个底层节点。
在一个实施例中，该第一测量子帧的相邻子帧中至少包括一个上行子帧。由于TDD系统的射频收发切换，频点带宽切换需要稳定时间。射频芯片往往会配置两个锁相环(PLL)分别作用于接收事件和发送事件，因此在接收事件和发送事件之间切换频点和带宽开销相对较小，而在两个接收事件之间切换频点和带宽开销较大，因此在设计上要尽量避免。而DUDMDDDUDDD的帧结构上存在接收和测量子帧相邻情况，子帧切换时会涉及频点和带宽的变化，导致测量子帧可能不到1ms，这会带来测量效率的降低，某些情况下甚至无法完成测量。为了避免这种情况，可以为该第一测量子帧的相邻子帧中至少配置一个上行子帧。例如，可以将第一通信系统的包括测量子帧的无线帧结构设置为DUMDDDDUDDD或DUDDDDUMDD。
进一步地，在一个实施例中，该多层星形无线网络包括高层节点，该通信设备的时间基准通过该高层节点获取。为了使多层星形无线网络中每个节 点的时间同步，可以由高层节点为该高层节点的下层节点发送时间基准。相应的，该通信设备的时间基准是通过该高层节点获取的。在一种实施方式中，该高层节点可以是RTK基站或顶层调度机。
本发明实施例中，通信设备可以获取第一通信系统的标识，并根据第一通信系统的标识确定第一通信系统的第一测量子帧的位置，使多个通信系统的测量子帧的位置不相同，可以避免各个通信系统获取工作频点的时间重叠的问题，可减低各个通信系统之间的无线干扰，提高通信质量。
基于上述对通信方法的描述，本发明实施例提供另一种通信方法，该方法可以应用于上述通信设备，本发明实施例主要体现不同的通信系统的包括测量子帧的无线帧的帧结构不同的情况。如图9所示，该通信方法可以包括如下步骤。
S901、通信设备获取第一通信系统的标识。
本发明实例中，该通信设备如何获取第一通信系统的标识请参见S201对应的说明，在此不赘述。
S902、该通信设备根据该第一通信系统的标识确定该第一通信系统的第一测量子帧的位置，该多个通信系统中的各个通信系统的测量子帧的位置不相同。
本发明实例中，该通信设备如何根据该第一通信系统的标识确定该第一通信系统的第一测量子帧的位置请参见S202对应的说明，在此不赘述。
其中，不同的通信系统的包括测量子帧的无线帧的帧结构不同。
S903、该通信设备根据该第一测量子帧的位置和配置时间间隔确定该第一通信系统的第二测量子帧的位置。
本发明实施例中，多层星形无线根据不同的通信系统的标识在第一个配置时间间隔内为不同的通信系统配置不同位置的测量子帧。多层星形无线可根据第一通信系统的第一测量子帧的位置和配置时间间隔配置后续的第一通信系统的测量子帧。因此，通信设备确定第一测量子帧的位置之后，可根据该第一测量子帧的位置和配置时间间隔确定该第一通信系统的第二测量子帧的位置。其中，该第二测量子帧可以是指配置于除第一个配置时间间隔以外的任一配置时间间隔内的任一测量子帧。
例如，如图3所示，一个配置时间间隔为一个无线帧的时长。第一通信系统的通信设备确定第一无线帧中的子帧2的位置为第一通信系统的第一测量子帧的位置之后，第一通信系统的通信设备根据第一无线帧中的子帧2的位置和配置时间间隔，确定第二无线帧中的子帧2的位置为第二无线帧的位置。
本发明实施例中，通信设备可以获取第一通信系统的标识，并根据第一通信系统的标识确定第一通信系统的第一测量子帧的位置，多个通信系统的测量子帧的位置不相同，可以避免各个通信系统获取工作频点的时间重叠的问题，可减低各个通信系统之间的无线干扰，提高通信质量。并且可以根据第一测量子帧的位置及配置时间间隔确定该第一通信系统的第二测量子帧，以便可以周期性的获取工作频点。
基于上述对通信方法的描述，本发明实施例提供又一种通信方法，该方法可以应用于上述通信设备，本发明实施例体现描述不同的通信系统的包括测量子帧的无线帧的帧结构相同的情况。如图10所示，该通信方法可以包括如下步骤。
S1001、通信设备获取第一通信系统的标识。
S1002、该通信设备根据该第一通信系统的标识确定该第一通信系统被轮流配置测量子帧的轮流配置次序。
其中，多层星形无线网络的多个通信系统中的各个通信系统的测量子帧的位置不相同。在一个所述配置时间间隔内，以目标时间为周期所述多个通信系统中的各个通信系统被轮流配置至少一个测量子帧，所述配置时间间隔为所述目标时间与所述多个通信系统中通信系统数量的乘积。各个通信系统包括测量子帧的无线帧的结构相同。
S1003、该通信设备根据该轮流配置次序确定该第一通信系统的第一测量子帧的位置。
其中，通信系统的标识与轮流配置的轮流配置次序具有对应关系。通信设备预先可存储该对应关系。或者，通信设备可以从上层节点获取第一通信系统的标识与轮流配置的轮流配置次序之间的对应关系。相应的，针对第一通信系统，通信设备可以根据第一通信系统的标识确定第一通信系统对应的 轮流配置次序，进而根据该轮流配置次序确定该第一通信系统的第一测量子帧的位置。例如，第一通信系统的标识与轮流配置次序1相对应，第二通信系统的标识与轮流配置次序2相对应，也就是说在一个配置时间间隔之内，先配置第一通信系统的测量子帧，再配置第二通信系统的测量子帧。例如，如图5所示，在第一无线帧中配置第一通信系统的测量子帧，在第二无线帧中配置第二通信系统的测量子帧。可选的，测量子帧在无线帧的位置可以是预先规定好的固定位置，例如，如图5所示，测量子帧在第一无线帧和第二无线帧的子帧2。通信设备确定轮流配置次序之后，就可确定第一无线帧的子帧2为第一通信系统的测量子帧。
S1004、该通信设备根据该目标时间及该多个通信系统中的通信系统数量确定配置时间间隔。即该配置时间间隔为该目标时间与该多个通信系统中通信系统数量的乘积，假设多层星形无线网络包括2个通信系统，第一时间时间为10ms，则2*10＝20ms，即配置时间间隔可以为20ms。
S1005、该通信设备根据该配置时间间隔及该第一测量子帧的位置确定该第一通信系统的第二测量子帧的位置。
例如，通信设备可以轮流配置各个通信系统的测量子帧，多层星形无线网络包括第一通信系统和第二通信系统，假设第一通信系统和第二通信系统的第一测量子帧如图5所示，则第一通信系统的第二测量子帧的位置为第一通信系统的第一测量子帧的位置加上配置时间间隔，即第一通信系统的第二测量子帧的位置为第三无线子帧中的子帧2所在的位置；第二通信系统的第二测量子帧的位置为第二通信系统的第一测量子帧的位置加上配置时间间隔，即第二通信系统的第二测量子帧的位置为第四无线子帧中的子帧2所在的位置。
本发明实施例中，通信设备可以获取第一通信系统的标识，该通信设备根据该第一通信系统的标识确定该第一通信系统被轮流配置测量子帧的轮流配置次序，根据该轮流配置次序确定该第一通信系统的第一测量子帧的位置。可以避免各个通信系统获取工作频点的时间重叠的问题，可减低各个通信系统之间的无线干扰，提高通信质量。并且可以根据该配置时间间隔及该第一测量子帧的位置确定该第一通信系统的第二测量子帧的位置，以便可以周期性的获取工作频点。
