具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请实施例的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”及“若”可以被解释成为“在……时”或“当……时”或“响应于确定”。
为了更好地描述本公开任一实施例，本公开一实施例以一个电表智能 控制系统的应用场景为例进行示例性说明。
如图1所示，本公开一实施例提供一种电表智能控制系统应用场景。请参见图2，电表智能控制系统包括电站控制中心21、接入点22、电表1、电表2和电表3等。需要说明的是，电站控制中心可以是电表智能控制系统中的智能网关。接入点可以是路由器。这里，电表为本公开实施例中的站点(STA，Station)。根据智能控制系统的调度需求，电站控制中心可以向接入点发送调度指令，指示接入点将存储的缓存数据配置给电表。这里，为了省电，电表可以是处于休眠状态，处于休眠状态的电表仍需要从接入点处获取缓存数据以实时执行对应的应用功能。
如图2所示，为本公开一实施例提供的一种进入休眠状态的站点获取缓存数据的方法示意图。请参见图2，站点在进入休眠状态之前，会与接入点协商苏醒周期来侦听信标帧(beacon)。站点周期性地苏醒以侦听接入点(AP，Access Point)发送的信标帧，并解析数据待传指示信息(TIM，Traffic Indication Map)，以获知接入点是否缓存有站点的下行数据帧。如果接入点缓存有站点的下行数据帧，则站点在竞争期内发送省电轮询帧(PS-poll，Power Saving poll)以获得资源来接收接入点缓存的下行数据。这里，发送省电轮询帧的方式包括两种：
第一种方式：站点在接收信标帧的连接下发送省电轮询帧，且在多个连接下同步接收缓存下行数据帧；
第二中方式：在每个连接下发送省电轮询帧，且在每个连接下独立接收缓存下行数据帧，在这种方式下，不同连接下接收的缓存下行数据帧的时间可相同或不同。如图3所示，为本公开一实施例提供的一种进入休眠状态的站点获取缓存数据的方法。请参见图3，站点在进入休眠状态之前会与接入点协商苏醒周期，周期性的在接入点规定的服务阶段(SP，service period)内获取接入点为其缓存的下行数据帧。这里，站点与接入点协商苏 醒周期。在非竞争期内，接入点通过非竞争轮询帧来发送接入点缓存的下行数据帧。这里，非竞争轮询帧由接入点发送给站点。这里，可以是在每个频段下发送，站点基于非竞争轮询帧接收缓存下行数据帧。
图2和图3示出的两种方式中，都是针对单连接进行数据传输的情况。为了提高系统的频谱利用效率，提高接入点和站点之间数据传输的速率和吞吐量，并降低数据传输的时延，需要设备在多连接下进行通信。这就需对以上两种方式进行增强，以适应多连接下的通信。这里，多连接可以是指一个频段下的多个带宽或是多个频段。
所述多个连接所使用的频率是不同的，例如，多个连接所使用的频率可以2.4GHz、5.8GHz及6-7GHz中的一个或多个。
如图4所示，本公开一实施例提供一种缓存的下行数据帧多连接下传输的指示方法。方法包括：
步骤S110，生成包含第一信息和第二信息的消息帧；其中，第一信息用于指示站点在接入点缓存有下行数据帧，第二信息用于指示站点在多连接下接收接入点缓存的下行数据帧；
在本实施例中，消息帧可以是接入点发送给站点的消息帧。例如，在电表智能控制系统中，路由设备为接入点，智能电表为站点，则消息帧可以是路由设备发送给智能电表的消息帧。这里，消息帧可以是信标帧(beacon)。还可以是非竞争轮询CF(contention-free)-poll帧。这里，多连接可以是指一个频段下的多个带宽/多个频段。这里，可以将多连接理解为多个传输数据的通道。多连接中的每个连接对应一个传输数据的通道，每个通道可以对应一个频段下的一个一个频段。需要说明的是，这里的“多连接下”还可以表述为为“多个连接下”、“多连接上”、“多个连接上”、“多传输连接上”、“多传输连接下”、“多个传输连接上”、“多个传输连接下”等。这里，接入点缓存的下行数据帧可以是接入点预先缓存的数据。还可 以是由第三方设备发送给接入点的数据。请再次参见图1，在智能电表智能控制系统中，接入点22缓存的下行数据帧可以是电表智能控制系统的电站控制中心21的设备发送给接入点22的数据。
在本实施例中，消息帧中可以包含不同的信息域，每个信息域可以包含多个比特位。每个比特位的取值为“1”或“0”时，分别代表指示不同的信息。这里，包含第一信息和第二信息的消息帧可以包含第一信息域和第二信息域。这里，第一信息域可以包含多个比特位，每个比特位可以关联一个站点。例如，1000个比特位可以关联1000个站点。当比特位取值为“1”时，代表比特位对应的站点在接入点缓存有下行数据帧。这里，可以是比特位位置对应的关联标识(AID，Association Identifier)指示的站点在接入点缓存有下行数据帧。这里，关联标识符是在接入点与站点进行关联时由接入点分配给站点的。当比特位取值为“0”时，代表对应比特位关联的站点在接入点没有缓存下行数据帧。这里，第二信息域可以包含多个比特位，每个比特位关联站点与接入点之间的一个连接。当比特位取值为“1”时，代表对应比特位关联的站点与接入点之间的连接可以进行下行数据帧的传输。当比特位取值为“0”时，代表对应比特位关联的站点与接入点之间的连接不能进行下行数据帧的传输。这里，站点在接收到包含第一信息和第二信息的消息帧后，可以通过解析消息帧的比特位对应的数值，获得第一信息和第二信息。这里，由于第一信息指示了站点在接入点缓存有下行数据帧，第二信息指示了站点在多连接下接收接入点缓存的下行数据帧，因此，站点可以确定在多连接下接收接入点缓存的下行数据。这里，可以是在当确定用于指示站点在接入点缓存有下行数据帧的第一信息时，确定用于指示站点在多连接下接收接入点缓存的下行数据帧的第二信息。需要说明的是，当第一信息域中的比特位设置为“0”时，第二信息域中的比特位不进行设置。
步骤S120，发送消息帧。
在本实施例中，消息帧可以是接入点周期性地向站点发送。站点通过接收到的消息帧获知接入点的存在。这里，站点和接入点之间的距离在设置范围内，以确保站点能够接收到接入点发送的消息帧。这里，接入点所在服务区域内可以包括多个站点。消息帧可以是通过广播的方式发送。
本公开实施例中，这样，站点在接收到消息帧后，基于第一信息能够获知在接入点缓存有需要获取的下行数据帧，基于第二信息能够获知可以在多连接下接收接入点缓存的下行数据帧。从而站点可以在多连接下接收接入点缓存的下行数据帧，提高了接入点和站点之间数据传输的速率和吞吐量，并降低了数据传输的时延。
如图5所示，本公开一实施例提供一种缓存的下行数据帧多连接下传输的指示方法。在步骤S110中，生成包含第一信息和第二信息的消息帧，包括：
步骤S210，当站点采用竞争的方式接收接入点缓存的下行数据时，生成包含第一缓存指示域和第一连接能力指示域的信标帧；其中，第一缓存指示域携带第一信息，第一连接能力指示域携带第二信息。
这里，站点是否采用竞争的方式接收接入点缓存的下行数据可以在无线网络组网时进行设置或者规定。接入点可以通过检测已经设置好或规定好的参数信息确定站点是否采用竞争的方式接收接入点缓存的下行数据。信标帧可以是无线通信中的管理帧。信标帧中可以包含数据待传指示信息(TIM，traffic indication map)。第一缓存指示域和第一连接能力指示域可以是设置在数据待传指示信息TIM域中。例如，请参见图6，第一缓存指示域可以是对应数据待传指示信息TIM域的关联标识符(AID，Association Identifier)域中。这里，关联标识符域包括的每个比特位可以关联一个站点。如果关联标识符域可以包含多个比特位，则关联标识符域可以关联多个站 点。例如，关联标识符的2008个比特位可以关联2008个站点。当站点对应的比特位为“1”时，代表站点在接入点缓存有下行数据帧。这里，第一缓存指示域承载第一信息包括的站点在接入点缓存有下行数据帧的信息。
需要说明的是，第一缓存指示域和第一连接能力指示域还可以设置在数据待传指示信息TIM域的其它信息域，例如图6中的X域，这里X域对应一个信息域，Y域原来可以是一个空白域。也可以是设置在信标帧中除数据待传指示信息TIM域之外的其它信息域中。例如，请参见图7，第一连接能力指示域设置在Y域，这里Y域对应一个信息域，Y域原来可以是一个空白域。Y域包括的每个比特位可以关联站点与接入点之间的一个连接。这里，第一连接能力指示域可以包含多个比特位，每个比特位关联一个连接。当连接对应的比特位为“1”时，代表该连接下可以进行数据传输。第一连接能力指示域承载了第二信息包括的站点能在多个连接下进行数据传输的信息。
在本实施例中，在第一连接能力指示域包括：多个第一子域，一个第一子域对应于接入点与站点之间的一个连接；生成包含第一缓存指示域和第一连接能力指示域的信标帧，包括：
生成包含第一缓存指示域和多个第一子域的信标帧，其中，连接的负载低于第一设置阈值时，对应的第一子域携带有使能连接的使能标识。
在本实施例中，第一缓存指示域可以与具体的站点关联，第一缓存指示域中比特位个数与站点的对应关系可以根据需求确定。例如，请参见图9，第一缓存指示域可以关联第一站点。第一缓存指示域可以是通过一个比特位关联一个站点。在检测到接入点缓存有发送给站点的下行数据帧时，这个比特位可以被设置为“1”。第一缓存指示域还可以是通过多个比特位关联一个站点。例如，第一缓存指示域通过3个比特位关联一个站点，则在检测到接入点有缓存的发送给站点的下行数据帧时，这3个比特位可以被 设置为“001”。
在本实施例中，第一子域跟接入点与站点之间的每个连接关联。例如，请参见图8，第一连接能力指示域包括多个第一子域。这里，多个第一子域分别与连接1、连接2、连接3、…、连接N关联。第一子域可以是对应一个比特位。以第一子域关联的连接是连接1为例，当连接1下连接的负载低于第一设置阈值时，这个比特位可以被设置为1。第一子域还可以是对应多个比特位。以第一子域关联的连接是连接1、第一子域包括3个比特位为例，当连接1下连接的负载低于第一设置阈值时，这3个比特位可以被设置为“001”。这里，多个第一子域在信标帧中可以是相邻设置，也可以是间隔设置。这里，第一设置阈值可以根据网络需求灵活设置。例如，当对连接的传输性能要求较高时，可以设置一个较低的第一设置阈值；当对连接的传输性能要求较低时，可以设置一个较高的第一设置阈值。这里，使能位的标识可以是包括第一子域对应比特位的取值。
请参见图9，在一实施例中，第一缓存指示域与第一站点关联。第一缓存指示域包括1个比特位，比特位携带有使能标识“1”，表示接入点缓存有第一站点的下行数据帧。第一连接能力指示域包括4个第一子域，4个第一子域分别关联接入点与站点之间的连接1、连接2、连接3和连接4。第一设置阈值设置为4。连接1对应连接了3个站点，连接2对应连接了2个站点，连接3对应连接了5个站点，连接4对应连接了1个站点。由于只有连接1、连接2、连接4满足负载低于第一设置阈值，因此，第一连接能力指示域的比特位被设置为1101。可以指示站点在连接1、连接2和连接3上接收接入点缓存的下行数据帧。
在本实施例中，生成包含第一信息和第二信息的消息帧，包括：
当站点采用非竞争的方式接收接入点缓存的下行数据时，生成包含第二缓存指示域和第二连接能力指示域的非竞争轮询CF(contention-free)-poll 帧；其中，第一缓存指示域携带第一信息，第二连接能力指示域携带第二信息。
这里，站点是否采用非竞争的方式接收接入点缓存的下行数据可以在无线网络组网时进行设置或者规定。接入点可以基于检测已经设置好或规定好的参数信息确定站点是否采用非竞争的方式接收接入点缓存的下行数据。第二缓存指示域和第二连接能力指示域可以是设置在非竞争轮询CF(contention-free)-poll帧包含的一个信息域中。例如，请参见图10，第二缓存指示域可以是对应非竞争轮询CF(contention-free)-poll帧包含的第一信息域中。这里，第二缓存指示域包括的每个比特位可以关联一个站点。这里，第二缓存指示域可以包含多个比特位，多个比特位可以关联多个站点。当站点对应的比特位为“1”时，代表站点在接入点缓存有下行数据帧。请再次参见图10，第二连接能力指示域设置在第二信息域，第二信息域包括的每个比特位可以关联站点与接入点之间的一个连接。这里，第二连接能力指示域可以包含多个比特位，多个比特位可以关联多个连接。当连接对应的比特位为“1”时，代表该连接下可以进行数据传输。
在本实施例中，第二连接能力指示域包括：多个第二子域，一个第二子域对应于接入点与站点之间的一个连接；
根据第二信息在多连接下接收接入点缓存的下行数据帧，包括：
根据第二连接能力指示域，在携带有使能标识的第二子域指示的多个连接上接收接入点缓存的下行数据帧。
在本实施例中，第二缓存指示域与站点关联。例如，请参见图11，第二缓存指示域关联第一站点。第二缓存指示域可以是通过一个比特位来关联一个站点。在检测到接入点有缓存的发送给站点的下行数据帧时，这个比特位可以被设置为1。第二缓存指示域还可以是通过多个比特位来关联一个站点。例如，第二缓存指示域通过3个比特位关联一个站点，则在检测 到接入点有缓存的发送给站点的下行数据帧时，这3个比特位可以被设置为001。
在本实施例中，第二子域与接入点与站点之间的每个连接关联。例如，请参见图11，多个第二子域分别于连接1、连接2、连接3、…、连接N关联。第二子域可以是通过一个比特位关联一个连接。以第二子域关联的连接是连接1为例，当连接1下连接的负载低于第二设置阈值时，这个比特位可以被设置为1。第二子域还可以是通过多个比特位关联一个连接。以第二子域关联的连接是连接1、第二子域通过3个比特位关联一个连接为例，当连接1下连接的负载低于第二设置阈值时，这3个比特位可以被设置为001。这里，多个第二子域在非竞争轮询CF(contention-free)-poll帧中可以是相邻设置，也可以是间隔设置。这里，第二设置阈值可以根据网络需求灵活设置。例如，当对连接的传输性能要求较高时，可以设置一个较低的第二设置阈值；当对连接的传输性能要求较低时，可以设置一个较高的第二设置阈值。这里，使能位的标识可以是包括第二子域对应比特位的取值。
请参见图12，在一实施例中，第二缓存指示域与第一站点关联。第二缓存指示域通过1个比特位与一个站点关联，比特位携带有使能标识“1”，表示接入点缓存有第一站点的下行数据帧。第二连接能力指示域包括4个第二子域，4个第二子域分别关联接入点与站点之间的连接1、连接2、连接3和连接4。第二设置阈值设置为4。连接1对应连接了3个站点，连接2对应连接了2个站点，连接3对应连接了5个站点，连接4对应连接了1个站点。由于只有连接1、连接2、连接4满足负载低于第二设置阈值，因此，第二连接能力指示域的比特位被设置为1101。可以指示站点在连接1、连接2和连接3上接收接入点缓存的下行数据帧。
如图13所示，本公开一实施例提供一种缓存的下行数据帧多连接下的 接收方法，应用于站点，其中，方法包括：
步骤S130，接收包含第一信息和第二信息的消息帧；
在本实施例中，消息帧可以是接入点发送给站点的消息帧。例如，在电表智能控制系统中，消息帧可以是路由设备发送给智能电表的消息帧。这里，消息帧可以是信标帧(beacon)。还可以是非竞争轮询CF(contention-free)-poll帧。
步骤S140，当第一信息指示接入点有缓存站点的下行数据帧时，根据第二信息在多连接下接收接入点缓存的下行数据帧。
这里，可以将多连接理解为多个传输数据的通道。例如，多连接中的每个连接对应一个传输数据的通道。需要说明的是，这里的多连接下还可以理解为多个连接下、多连接上、多个连接上、多传输连接上、多传输连接下、多个传输连接上、多个传输连接下等。这里，接入点缓存的下行数据帧可以是接入点预先存储的数据，还可以是由第三方设备发送给接入点的数据。例如，请再次参见图1，在电表智能控制系统中，接入点22缓存的下行数据帧可以是控制中心21发送的数据。
在本实施例中，消息帧中可以包含不同的信息域。每个信息域可以包含多个比特位，每个比特位取值为“1”或“0”时，分别代表指示不同的信息。这里，包含第一信息和第二信息的消息帧包含第一信息域和第二信息域。这里，第一信息域可以包含多个比特位，每个比特位可以关联一个站点。当比特位取值为“1”时代表比特位对应的站点在接入点缓存有下行数据帧。这里，可以是比特位位置对应的关联标识(AID，Association Identifier)指示的站点在接入点缓存有下行数据帧。这里，关联标识符是在接入点与站点进行关联时有接入点分配给站点的。当比特位取值为“0”时，代表对应比特位对应的站点在接入点没有缓存下行数据帧。这里，第二信息域包含多个比特位，每个比特位关联站点与接入点之间的一个连接。当 比特位取值为“1”时，代表对应比特位关联的站点与接入点之间的连接可以进行下行数据帧的传输。当比特位取值为“0”时，代表对应比特位关联的站点与接入点之间的连接不能进行下行数据帧的传输。这里，站点在接收到包含第一信息和第二信息的消息帧后，可以解析消息帧的比特位对应的数值，获得第一信息和第二信息。由于第一信息指示了站点在接入点缓存有下行数据帧，第二信息指示了站点在多连接下接收接入点缓存的下行数据帧，因此，站点可以确定在多连接下接收接入点缓存的下行数据。
在本实施例中，消息帧可以是定期被站点接收，站点通过接收到的消息帧获知接入点的存在。这里，站点和接入点之间的距离在设置范围内，以确保站点能够接收到接入点发送的消息帧。这里，接入点所在服务区域内可以包括多个站点。消息帧可以是通过广播的方式发送。
在本实施例中，接收包含第一信息和第二信息的消息帧，包括：
当采用竞争的方式获取接入点缓存的下行数据时，接收包含第一缓存指示域和第一连接能力指示域的信标帧；其中，第一缓存指示域携带第一信息，第一连接能力指示域携带第二信息。
这里，站点是否采用竞争的方式接收接入点缓存的下行数据可以在无线网络组网时进行设置或者规定。接入点可以基于检测已经设置好或规定好的参数信息确定站点是否采用竞争的方式的方式接收接入点缓存的下行数据。信标帧可以是无线通信中的管理帧。信标帧中可以包含数据待传指示信息(TIM，traffic indication map)域。第一缓存指示域和第一连接能力指示域可以是设置在数据待传指示信息TIM域中。例如，请再次参见图7，第一缓存指示域可以是对应数据待传指示信息TIM域的关联标识符(AID，Association Identifier)域中。这里，关联标识符包括的每个比特位可以关联一个站点。这里，关联标识符可以包含多个比特位。当站点对应的比特位为“1”时，代表站点在接入点缓存有下行数据帧。
需要说明的是，第一缓存指示域和第一连接能力指示域还可以设置在数待传指示信息TIM域的其它信息域，例如图6中的X域。也可以是设置信标帧的其它信息域中。例如，请再次参见图7，第一连接能力指示域设置在除数待传指示信息TIM域之外的Y域，Y域包括的每个比特位可以关联站点与接入点之间的一个连接。这里，第一连接能力指示域可以包含多个比特位，多个比特位关联多个连接。当连接对应的比特位为“1”时，代表该连接下可以进行数据传输。

当采用非竞争的方式接收接入点缓存的下行数据时，接收包含第一缓存指示域和第二连接能力指示域的非竞争轮询CF(contention-free)-poll帧；其中，第一缓存指示域携带第一信息，第二连接能力指示域携带第二信息。
这里，站点是否采用非竞争的方式接收接入点缓存的下行数据可以在无线网络组网时进行设置或者规定。接入点可以基于检测已经设置好或规定好的参数信息确定站点是否采用非竞争的方式的方式接收接入点缓存的下行数据。第二缓存指示域和第二连接能力指示域可以是设置在非竞争轮 询CF(contention-free)-poll帧包含的一个信息域中。例如，请再次参见图10，第二缓存指示域可以是对应非竞争轮询CF(contention-free)-poll帧包含的第一信息域中。这里，第二缓存指示域包括的每个比特位可以关联一个站点。这里，第二缓存指示域可以包含多个比特位。当站点对应的比特位为“1”时，代表对应站点在接入点缓存有下行数据帧。第二信息包括站点在接入点缓存有下行数据帧的信息。请再次参见图10，第二连接能力指示域设置在第二信息域，第二信息域包括的每个比特位可以关联站点与接入点之间的一个连接。这里，第二连接能力指示域可以包含多个比特位。当连接对应的比特位为“1”时，代表该连接下可以进行数据传输。

在本实施例中，第二子域与接入点与站点之间的每个连接关联。例如，请再次参见图11，多个第二子域分别于连接1、连接2、连接3、…、连接N关联。第二子域可以是通过一个比特位关联一个站点。以第二子域关联的连接是连接1为例，当连接1下连接的负载低于第二设置阈值时，这个 比特位可以被设置为1。第二子域还可以是通过多个比特位关联一个站点。以第二子域关联的连接是连接1、第二子域通过3个比特位关联一个站点为例，当连接1下连接的负载低于第二设置阈值时，这3个比特位可以被设置为001。这里，多个第二子域在非竞争轮询CF(contention-free)-poll帧中可以是相邻设置，也可以是间隔设置。这里，第二设置阈值可以根据网络需求灵活设置。例如，当对连接的传输性能要求较高时，可以设置一个较低的第二设置阈值；当对连接的传输性能要求较低时，可以设置一个较高的第二设置阈值。这里，使能位的标识可以是包括第二子域对应比特位的取值。
请再次参见图12，在一实施例中，第二缓存指示域与第一站点关联。第二缓存指示域通过1个比特位关联一个站点，比特位携带有使能标识“1”，表示接入点缓存有第一站点的下行数据帧。第二连接能力指示域包括4个第二子域，4个第二子域分别关联接入点与站点之间的连接1、连接2、连接3和连接4。第二设置阈值设置为4。连接1对应连接了3个站点，连接2对应连接了2个站点，连接3对应连接了5个站点，连接4对应连接了1个站点。由于只有连接1、连接2、连接4满足负载低于第二设置阈值，因此，第二连接能力指示域的比特位被设置为1101。可以指示站点在连接1、连接2和连接4上接收接入点缓存的下行数据帧。
