Description

数据发送、数据接收方法及装置、接入点、站点 技术领域
本公开涉及通信领域，例如涉及一种数据发送、数据接收方法及装置、接入点、站点。
背景技术
随着物联网行业快速发展，大量物联网设备接入网络，通过有线或者无线的方式互相连接，遍及智能交通、环境保护、政府工作、公共安全、平安家居、智能消防、工业监测、老人护理、个人健康、水系监测、食品溯源等多个领域。物联网应用中涉及的物联网设备数量巨大，可以称之为海量终端。这些终端大多通过电池供电进行工作。在多数应用场景中，如水质监测、环境监测和工业监测中，设备的安装地点并不容易随时进行检测维修，以及更换电池，在另一些场景中，如智能交通，电力抄表，服务提供商也希望设备一旦安装，可以长达数月甚至数年无需更换电池，这就需要物联网设备具有高性能的省电机制。
在多类省电机制中，其中一种方法是为具备无线通信能力的物联网设备增加一个超低功耗的监听唤醒模块，该监听唤醒模块的工作原理如下：当此监听唤醒模块开启时，设备可以关闭其他模块，例如传感器模块、微处理器模块、存储器模块、无线通信模块等等，仅保留监听唤醒模块工作，下文称设备的这种工作状态为省电状态。监听唤醒模块需要监听是否有发送给自己的唤醒信号，一旦收到，则根据唤醒信号的要求，触发其他模块进行工作，例如开启微处理模块，开启无线通信模块等，下文称这一过程为唤醒。
利用无线局域网技术提供物联网服务，是一种简单可行的方案。以无线网 中常见的设备：接入类站点，简称接入点(Access Point，AP)以及非接入类站点，简称站点(non-AP STA，STA)为例，说明上述工作方式。一个AP建立一个基本服务集(Basic Service Set，BSS)，STA为与该AP关联的一个无线设备，为该STA增加监听唤醒模块，则该STA在没有业务的情况下可以仅保留监听唤醒模块工作，用于接收唤醒信号。一段时间之后，AP需要向STA发送下行数据，则AP首先发送唤醒信号给STA，STA的监听唤醒模块收到唤醒信号，确认该唤醒信号是发送给自己的，则根据唤醒信号的内容，开启其他模块，执行相关操作，例如接收来自AP的下行数据。
在物联网络中，多数站点可能处于省电状态，当AP缓存有多个站点的数据时，需要唤醒多个站点并进行数据传输。AP可以在发送唤醒信号后的特定时间后盲发下行数据，但无法保证站点有效接收下行数据；或者AP收到站点对唤醒信号的回应后便可确认站点的主模块已进入清醒状态，为该站点发送下行数据。此方法可以确保有效地为已被唤醒的站点发送下行数据，但是站点如何快速高效地回应唤醒信号，既要避免碰撞传输又要提高响应速度以便站点能尽快接收到下行数据，是亟待解决的问题。

通过上述步骤，由于在用于唤醒一个或者多个站点的第一无线信号中指示了一个或者多个站点响应第一无线信号的方式，使得一个或者多个站点可以根据指示的响应方式快速高效的回应是否被唤醒，因此，可以解决相关技术中站点进入省电或者休眠状态时，无法快速高效的回应唤醒信号的问题。

可选地，在第二无线信道上接收一个或者多个站点发送的第二无线信号之前，本实施例提供的数据发送方法还包括：当第一无线信号携带有等待触发信息和唤醒类型指示信息中的至少一个时，在第二无线信道上向一个或者多个站 点发送第三无线信号，其中，第三无线信号包含以下信息至少之一：为一个或者多个站点在第二无线信道上以多用户正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)信号方式发送第二无线信号所配置的发送参数，为一个或者多个站点在第二无线信道上发送第二无线信号分配的专有资源信息，为一个或者多个站点在第二无线信道上发送第二无线信号分配的随机接入的资源信息，一个或者多个站点的标识信息，触发信号类型指示信息，信道检测请求信息，其中，触发信号类型指示信息指示第三无线信号为寻呼响应触发信息，信道检测请求信息用于指示是否请求一个或者多个站点在发送第二无线信号前检测专有资源或者选择的随机接入资源上的信道空闲状态。
通过上述步骤，可以避免唤醒的一个或者多个站点间的竞争碰撞，使得无线设备能高效地进行寻呼响应，从而达到省电模式设备进入清醒状态后能够高效地进行数据接收，在省电的同时，有效地利用空口资源。
可选地，上述实施例可以是第一无线信号携带有等待触发信息的指示信息的情况即第一无线信号请求站点在所述第二无线信道上等待接收第三无线信号的情况。而在第一无线信号不携带有等待触发信息的指示信息的情况时，即第一无线信号请求站点在所述第二无线信道上不等待接收第三无线信号的情况时，则在向一个或多个站点发送第一无线信号后等待站点反馈的第二无线信号。在预定时间后内未收到标识信息对应的部分或全部站点反馈的第二无线信号，继续发送第一无线信号直到达到阈值或直到获知标识信息对应的部分或全部站点已在其它区域被唤醒。
可选地，在第二无线信道上接收一个或者多个站点发送的第二无线信号包括：在专有资源上接收标识信息对应的站点发送的第二无线信号，或者，在随机接入的资源上接收标识信息对应的站点发送的第二无线信号。

可选地，在第二无线信道上接收一个或者多个站点发送的第二无线信号包括：在发送第一无线信号后在第二预定时间内等待接收一个或者多个站点发送的第二无线信号；在第二预定时间内未收到标识信息对应的部分或全部站点发送的第二无线信号，继续发送第一无线信号直到发送次数达到第二阈值或直到获知标识信息对应的部分或全部站点已在其它区域被唤醒。
可选地，第二无线信号中包含以下信息至少之一：站点的关联标识(Associated ID，AID)，站点的所关联的基本服务集标识(Basic Service Set ID，BSSID)，站点的媒体访问控制(Media Access Control，MAC)地址，站点的寻呼标识。

在步骤304中，在第二无线信道上发送第二无线信号。
在步骤306中，在第二无线信道上接收数据。
通过上述步骤，由于接收到的用于唤醒站点的第一无线信号中指示了站点反馈一个或者多个站点已被唤醒的方式，使得站点可以根据指示的响应方式快速高效的回应是否被唤醒，因此，可以解决相关技术中站点进入省电或者休眠状态时，无法快速高效的回应唤醒信号的问题。
可选地，第一无线信号中携带有以下信息至少之一：一个或者多个站点的标识信息，唤醒类型指示信息，等待触发信息的指示信息，预定时间信息，其中，唤醒类型指示信息用于指示一个或者多个站点在接入点上有待发送的数据，等待触发信息的指示信息用于请求所述一个或者多个站点在所述第二无线信道上等待接收第三无线信号；预定时间信息用于指示一个或者多个站点在接收到第一无线信号后的第三预定时间内在第二无线信道上接收第三无线信号。

可选地，在第二无线信道上发送第二无线信号包括：第三无线信号若第一无线信号中携带非零预定时间信息，则在预定时间后，若未接收到在第二无线信道上发送的第三无线信号，在第二无线信道上竞争发送第二无线信号；若第一无线信号中未携带预定时间信息，则在站点预配置的时间后，在第二无线信道上竞争发送第二无线信号，其中，竞争发送是指采用系统预定的接入等级发送。

例如，本实施例提出了一种省电设备的唤醒方法和装置，无线设备在进入休眠状态后，仅保持唤醒监听模块监听唤醒信号。当监听到唤醒信号后，无线设备通知唤醒设备的主模块已经进入清醒状态准备接收数据。为了及时地进行寻呼响应，同时又要避免多个无线设备竞争碰撞导致效率下降的情况，提出上述数据发送方法和数据接收方法，使得无线设备能高效地进行寻呼响应，从而达到省电模式设备进入清醒状态后能够高效地进行数据接收，在省电的同时，有效地利用空口资源。
下面分别以单用户唤醒及寻呼响应、多用户唤醒及寻呼响应对上述实施例进行说明。
图4是根据本实施例的单用户唤醒及寻呼响应示意图一，图5是根据本实施例的单用户唤醒及寻呼响应示意图二，下面结合图4和图5对单用户唤醒及寻呼响应进行说明。
在无线局域网中，一个AP建立一个BSS。无线局域网中的站点处于一个BSS的覆盖范围内，与该BSS关联，并与该BSS的AP进行通信。若此站点进入省电模式，为达到即省电又能快速被唤醒以便进行数据通信的目的，站点通常关闭主模块，保持省电监听模块监听AP发送的唤醒信号(相当于上述第一无线信号)。当AP有该站点的下行数据时，首先唤醒该站点，确保该站点主模块进入清醒状态，然后与该站点进行正常通信。
AP向特定站点发送单播的唤醒信号，此信号中携带该站点的标识信息，该标识可以是站点在所关联的BSS内的局域标识或站点在寻呼区域内的唯一标识 或站点在所关联的BSS内的局域标识与所关联的BSS标识的组合。唤醒信号中还可以指示唤醒目的为发送下行缓存数据，还可以携带是否请求站点被唤醒后等待触发信息的指示信息。当AP在唤醒信号中携带并指示请求站点被唤醒后等待触发信息时，AP将在发送唤醒信号后的一段时间内发送触发信号，所述触发信号可以为单播或组播信号。该触发信号中携带为多个站点分配的专有上行资源或随机接入资源。若站点收到了唤醒信号，则唤醒该站点的主模块，使主模块由休眠状态进入清醒状态，并进行如下操作至少之一。
操作一：如图4所示，站点的主模块等待接收AP发送触发信号。若接收到的触发信号中为该站点分配了专有的上行资源，则在接收到触发信号后的特定帧间间隔(相当于第四预定时间)，例如SIFS(Short Inter frame space，SIFS)后，被唤醒的每个站点在各自所分配的专有资源上发送寻呼响应信息；若接收到的触发信号中分配了上行随机接入资源，则在接收到触发信号后的特定帧间间隔(Inter frame space，IFS)后，被唤醒的每个站点在所分配的多个随机接入资源单元(Resource Unit，RU)中根据特定条件选取其中一个RU发送寻呼响应信息。本例中寻呼响应信息可以为PS-POLL MAC帧。该MAC帧中包含以下信息至少之一：站点的局部标识，即关联标识AID(Associated ID)，所关联的BSS的MAC地址，站点的MAC地址等信息。此寻呼响应信息可以承载在上行多用户响应无线帧中，例如上行多用户OFDMA格式的无线帧。
操作二：如图5所示，站点的主模块进入清醒状态后，首先监听信道，当监听到一个无线帧并被该无线帧的时间信息设置了网络分配矢量(Network Allocation Vector，NAV)后，或者等待了一个特定探测延时(Probe Delay)后，站点按照竞争接入机制，例如增强型分布式信道接入机制(Enhanced Distributed Channel Access，EDCA)，进行信道接入。站点主模块可以采用最高或较高的接 入优先级，例如使用语音类业务或视频类业务对应的接入优先级(Access Category_Voice，AC-VO，或Access Category_Video，AC-VI)的EDCA接入参数进行退避竞争。当退避结束时，站点发送寻呼响应无线帧PS-POLL。
当AP在唤醒信号中未携带或指示不会发送触发信息时，AP将在发送唤醒信号后等待站点发送寻呼响应无线帧PS-POLL。站点在接收到唤醒信号后，依照上述操作二的方式发送寻呼响应无线帧PS-POLL。
当AP在唤醒信号中指示会发送触发信息时，站点在接收到唤醒信号后，可以依照上述操作一和操作二中的至少一种方式发送寻呼响应无线帧PS-POLL。
图6是根据本实施例的多用户唤醒及寻呼响应示意图一，图7是根据本实施例的多用户唤醒及寻呼响应示意图二，图8是根据本实施例的多用户唤醒及寻呼响应示意图三，下面结合图6、图7和图8对多用户唤醒及寻呼响应进行说明。
在无线局域网中，一个AP建立一个BSS。无线局域网中的站点处于一个BSS的覆盖范围内与该BSS关联，并与该BSS的AP进行通信。若多个站点进入省电模式，为达到即省电又能快速被唤醒以便进行数据通信的目的，这些站点通常关闭主模块，保持省电监听模块监听AP发送的唤醒信号(相当于上述第一无线信号)。当AP有这些站点的下行数据时，首先发送唤醒信号，确保这些站点的主模块进入清醒状态，然后与该站点进行正常通信。
为了减少唤醒信号的开销，AP可以向一组站点发送组播的唤醒信号，此信号中携带该组站点的标识信息，该组标识可以是站点在所关联的BSS内的局域标识集合或组标识，或者是站点在寻呼区域内的唯一标识集合或组标识，或者站点在所关联的BSS内的局域标识集合与所关联的BSS标识的组合。唤醒信号中还可以指示唤醒目的为发送下行缓存数据，进一步还可以携带是否请求站点 被唤醒后等待触发信息的指示信息。当AP在唤醒信号中携带并指示请求该组站点被唤醒后等待触发信息时，AP将在发送唤醒信号后的一段时间内发送触发信号，所述触发信号可以为单播或组播信号。该触发信号中携带为站点分配的专有上行资源或随机接入资源。
若站点收到了唤醒信号，则唤醒其主模块，使主模块由休眠状态进入清醒状态，并进行如下操作，如图6所示。
站点的主模块等待接收AP发送触发信号。若接收到的触发信号中为该站点分配了专有的上行资源，则在接收到触发信号后的特定帧间间隔(Inter frame space，IFS)后，在所分配的专有资源上发送寻呼响应无线帧；若接收到的触发信号中分配了上行随机接入资源，则在接收到触发信号后的特定帧间间隔，例如SIFS(Short Inter frame space，SIFS)后，在所分配的多个随机接入资源单元(Resource Unit，RU)中根据特定条件选取其中一个RU发送寻呼响应。本例中寻呼响应可以为PS-POLL MAC帧。该MAC帧中包含以下信息至少之一：站点的局部标识，即关联标识AID(Associated ID)，所关联的BSS的MAC地址，站点的MAC地址等信息。所述多个站点的寻呼响应可以承载在上行多用户响应无线帧中。
当AP在唤醒信号中未携带或指示不会发送触发信息时，每个站点的主模块进入清醒状态后，首先监听信道，当监听到一个无线帧并被该无线帧的时间信息设置了网络分配矢量(Network Allocation Vector，NAV)后，或者等待了一个特定探测延时(Probe Delay)后，站点按照竞争接入机制，例如增强型分布式信道接入机制(Enhanced Distributed Channel Access，EDCA)，进行信道接入。由于AP的唤醒信号包含多个站点，如果采用高优先级接入参数，竞争窗口较小，多个被唤醒站点可能同时竞争信道造成碰撞，如图7所示。为了避免多个被唤 醒的站点的竞争碰撞，每个站点可以采用较低的接入优先级，例如使用背景类业务或尽力而为类业务对应的接入优先级(Access Category_Background，AC-BK，或Access Category_Best Effort，AC-BE)的EDCA接入参数进行退避竞争。当某个站点的退避结束时，该站点发送寻呼响应无线帧PS-POLL，如图8所示。
站点可以基于触发信号的寻呼响应，下面对站点基于触发信号的寻呼响应过程进行描述。
例如，根据上述实施例，AP发送了唤醒信号给一个或多个站点。若唤醒信号携带并指示请求站点被唤醒后等待触发信号，则AP在唤醒信号之后的一段时间发送触发信号。若在触发信号中AP为站点分配专有的资源，在触发信号后的特定帧间间隔IFS后，站点忽略当前物理或虚拟的信道检测结果，即不考虑在IFS时间内信道是否空闲，直接在所分配的资源上发送寻呼信号来响应AP的触发信号。若在触发信号中AP分配了随机接入资源，在触发信号后的特定帧间间隔IFS后，站点根据特定条件随机选择一个随机接入资源单元RU，并且忽略当前物理或虚拟的信道检测结果，即不考虑在IFS时间内所选择的RU信道是否空闲，直接在所选择的RU上发送寻呼信号来响应AP的触发信号。
AP在触发信号之后的特定时间内若没有收到部分或全部指定站点的寻呼信号，可以多次发送唤醒信号和触发信号中的至少一个，直到最大发送次数或收到高层通知所唤醒站点已经在其它BSS内唤醒。
又例如，根据上述实施例，AP发送了唤醒信号给一个或多个站点。若唤醒信号指示唤醒目的为发送下行缓存数据但未携带或未指示请求站点被唤醒后等待触发信号，则AP在唤醒信号之后的一段时间内等待站点主动竞争发送寻呼响应信号。若在特定时间内没有收到部分或全部指定站点的寻呼信号，可以多次 发送唤醒信号，直到最大发送次数或收到高层通知所唤醒站点已经在其它BSS内唤醒。此特定时间可以为探测延迟probe delay时间。
又例如，AP发送了唤醒信号给一个或多个站点。唤醒信号中包含了一个业务指示比特映射信息，具体可以包含以下信息至少之一：起始站点标识信息，业务指示比特映射图，业务指示比特映射图长度信息；其中，业务指示比特映射图中的每个比特表示对应站点是否有待发送的数据。站点根据指示的起始站点标识信息或者默认的起始站点标识信息，以及业务指示比特映射图长度确定该组站点的标识范围。若站点的标识属于在该组站点的标识范围以内，则根据业务指示比特映射图中的对应自己的比特确定是否有待发送的数据，比特置“1”，表示有待发数据，否则表示无待发数据。
当确定有自己的待发数据后，即为被唤醒站点。
当站点接收到唤醒信号并判断自己为被唤醒站点时，即默认等待接收触发信号，若在站点默认的预定时间内未接收到触发信号，则可以主动竞争信道并发送寻呼响应信号。为减小多个站点竞争接入碰撞的概念，站点采用系统预定义的较低接入等级所对应的接入参数竞争信道，例如AC-BE或AC-BK接入等级。
又例如，AP在唤醒信号中指示请求站点等待触发信号，并携带预定时间信息指示被唤醒站点在接收到唤醒信号后的预定时间内等待触发信号。当站点接收到唤醒信号并判断自己为被唤醒站点时，即等待接收触发信号，若在预定时间内未接收到触发信号，则可以主动竞争信道并发送寻呼响应信号。为减小多个站点竞争接入碰撞的概念，站点采用系统预定义的较低接入等级所对应的接入参数竞争信道，例如AC-BE或AC-BK接入等级。

  45. 根据权利要求43所述的站点，其中，所述第三发送装置，还设置为若所述第一无线信号中携带非零预定时间信息，则在所述预定时间后，未接收到在所述第二无线信道上发送的第三无线信号时，在所述第二无线信道上竞争发送所述第二无线信号；若所述第一无线信号中未携带预定时间信息，则在站点预配置的时间后，在所述第二无线信道上竞争发送所述第二无线信号，其中，竞争发送是指采用系统预定的接入等级发送。
  46. 根据权利要求44所述的站点，其中，所述第三发送装置，还设置为若所述信道检测请求信息指示请求所述一个或者多个站点在发送所述第二无线信号前检测所述专有资源或者选择的随机接入资源上的信道空闲状态，则在接收到所述第三无线信号后的第四预定时间内进行信道检测，当信道检测为空闲时， 在所述第四预定时间后发送所述第二无线信号，其中，所述信道检测包括以下至少之一：虚拟信道检测，物理信道检测；若所述信道检测请求信息指示不请求所述一个或者多个站点在发送所述第二无线信号前检测所述专有资源或者选择的随机接入资源上的信道空闲状态，或所述第三无线信号中未携带信道检测请求信息，则在接收到所述第三无线信号后的所述第四预定时间后发送所述第二无线信号。
  47. 根据权利要求43所述的站点，其中，所述第三发送装置，还设置为根据所述第一无线信号中所述站点的标识信息和唤醒类型指示信息中的至少一个判断所述站点是否为被唤醒站点；在判断结果为是的情况下，判断所述站点是否是所述第一无线信号唤醒的唯一站点；在判断结果为是的情况下，唤醒所述第二无线信道上的主装置，并以第一预定接入优先级竞争信道发送所述第二无线信号；在判断结果为否的情况下，唤醒所述第二无线信道上的主装置，并以第二预定接入优先级发送所述第二无线信号；所述第一预定接入优先级高于所述第二预定优先级。
  48. 根据权利要求42至47中的任一项所述的站点，其中，所述第二无线信号包含以下信息至少之一：所述站点的关联标识AID，所述站点的所关联的基本服务集标识BSSID，所述站点的媒体访问控制MAC地址，所述站点的寻呼标识。
  49. 一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令用于执行权利要求1-16任一项的方法。
