Description
本申请涉及但不限于无线通信技术,尤指一种设备唤醒方法和设备。
目前,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。
在各类省电机制中,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省电模块,该省电模块的工作原理如下:当此省电模块开启时,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,仅保留省电模块工作,这种工作状态可称为省电状态或省电模式。省电模块在工作时耗电量极低,一般在微瓦级别。省电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,这一过程可称为唤醒过程。
以无线网中常见的设备:接入点(AP,Access Point)以及非接入站点(STA,non-AP STA)为例,说明上述工作方式。一个AP建立一个基本服务集(BSS,Basic Service Set),STA为与该AP关联的一个无线设备,为该STA增加省电模块,则该STA在没有业务数据的情况下可以仅保留省电模块工作,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的省电模块收到唤醒信号,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。
发明概述
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
在某些情况下,STA处于仅保留省电模块工作的省电模式下时,可能进行移动,从而移出了原关联AP的覆盖范围。例如货运场景中,每箱货物被安装无线跟踪设备,当货物进入物流环节,很快会移出原AP的覆盖范围。此时,可能出现的情况是:原AP无法获知STA的位置情况,则当网络侧有需要发送给该STA的数据时,原AP发送唤醒信号时,无法唤醒相应设备,原AP在没有响应的情况下可能多次重发唤醒信号,导致空口资源的浪费,且不利于AP省电。另一方面,STA进入其他AP的覆盖范围,而其他AP并没有获得通知,其他AP也不会负责唤醒该STA,这就出现了STA无法被唤醒的情况。

详述
下面结合附图对本发明的实施例作进一步详细的说明。
实施例一
在无线局域网中,一个AP建立一个BSS,该BSS根据AP的发射功率以及天线配置情况,具有一定的覆盖范围,无线局域网中的站点处于某个BSS的覆盖范围内,若此站点进入省电模式,为达到唤醒该站点的效果,本实施例中建立若干寻呼集合。每个寻呼集合包括一定数量的BSS,可以包括至少一个BSS。并且,由于若干BSS可以组成一个扩展服务器集(ESS,Extended Service Set),因此,每个寻呼集合内的若干BSS还可以组成一个ESS,或者组成多个ESS,当然,也可以不组成ESS。一个BSS还可以属于多个寻呼集合。寻呼集合中BSS的数量设置需要合适,在保证覆盖的前提
下,数量不能过多,防止每次寻呼有太多数量的AP发送消息导致信道碰撞加剧,也不能太小,防止站点频繁检测到寻呼集合变化,进行上报。
图1为本发明实施例的寻呼集合的网络拓扑结构示意图;上述寻呼集合的实例可如图1所示。寻呼集合1包括三个BSS:BSS1、BSS2和BSS8,且BSS1,BSS2和BSS8组成了一个ESS1。寻呼集合2包括四个BSS:BSS3、BSS4、BSS5和BSS6,其中,BSS3和BSS4组成了ESS2,BSS5和BSS6组成了ESS3。寻呼集合3包含两个BSS:BSS7和BSS8,这两个BSS并没有组成ESS。可以看出,BSS8属于两个寻呼集合:寻呼集合1和寻呼集合3。在图1中,为多个寻呼集合配置了一个寻呼集合管理实体,所述寻呼集合管理实体用于管理寻呼集合1、寻呼集合2和寻呼集合3。管理实体的功能举例包括:
为每个寻呼集合分配寻呼集合标识;
维护每个寻呼集合的BSS列表和/或ESS列表;
当收到AP的请求消息时,根据所述请求消息,为与所述AP关联或未关联的站点分配或重分配唤醒标识,保证该唤醒标识在AP所在的寻呼集合内、或者ESS内、或者BSS内的唯一性,或者在整网内的唯一性;
维护站点与其唤醒标识,以及维护所述站点与其所在的BSS、ESS和寻呼集合的对应关系;
当识别到一个站点离开一个寻呼集合时,释放所述站点所占用的唤醒标识,识别方式可以是通过AP的报告;
触发至少一个寻呼集合内的至少一个AP发送携带至少一个唤醒标识的第一无线信号,以唤醒站点。被唤醒的站点可以是与AP关联或者未关联的站点。
图2为本发明实施例的寻呼集合的另一种网络拓扑结构示意图;如图2所示,不同于图1,在本示意中,为每个寻呼集合配置一个寻呼集合管理实体,在多个寻呼集合管理实体之上,还可能存在一个管理模块,负责对多个寻呼集合管理实体进行管理。管理多个寻呼集合管理实体的模块可以位于任一寻呼集合管理实体当中,也可以位于其他实体上。每个寻呼集合管理实体
的功能举例如下:
获取自身寻呼集合标识;
维护自身寻呼集合的BSS列表和/或ESS列表;
当收到AP的请求消息,根据所述请求消息,为与所述AP关联或未关联的站点分配或重分配唤醒标识,保证该唤醒标识在寻呼集合内、或者ESS内、或者BSS内的唯一性,或者在整网内的唯一性;
维护站点与其唤醒标识,以及维护所述站点与其所在的BSS,ESS的对应关系;
当识别到一个站点离开寻呼集合,释放所述站点所占用的唤醒标识,识别方式可以是通过AP的报告;
触发寻呼集合内的至少一个AP发送携带至少一个唤醒标识的第一无线信号,所述第一无线信号用于唤醒站点。被唤醒的站点可以是与AP关联或者未关联的站点。
在本发明各实施例中,寻呼集合管理实体是一个功能实体,一般位于网络侧,可以是AP层之上的接入控制器(AC,Access Controller)设备内的功能实体,也可以位于AP内,也可以位于终端侧。
采用本发明实施例的设备唤醒方法和设备,针对无线设备发生移动进而导致的无法被唤醒的情况,使得无线设备在移动过程中能够监测网络变化,并将自身的位置信息上报给网络,从而达到处于省电模式时能够准确地被唤醒的效果,在省电的同时,节约了空口资源。
实施例二
本发明实施例提供了一种设备唤醒方法。本实施例可以为寻呼集合管理实体的寻呼策略。图3为本发明实施例的设备唤醒方法的第一种流程示意图;如图3所示,所述方法包括:
步骤101:寻呼集合管理实体触发至少一个寻呼集合内的至少一个接入点发送第一无线信号;所述第一无线信号用于唤醒与所述接入点关联或未关联的站点;其中,所述寻呼管理实体管理至少一个寻呼集合。其中,每个寻呼集合中包括至少一个BSS,每个寻呼集合中的至少一个BSS可以组成至
少一个ESS,或者寻呼集合中的BSS不组成ESS;所述寻呼集合管理实体为所述寻呼集合内的与接入点关联或未关联的站点分配或重分配唤醒标识;所述唤醒标识在特定范围内具有唯一性;所述特定范围包括:基本服务集BSS、扩展服务器集ESS、寻呼集合或整个网络。
本实施例中,所述唤醒标识的取值根据以下参数的至少之一按运算获得:站点的介质访问控制MAC地址、站点的关联标识、站点所在的基本服务集BSS标识、站点所在的ESS标识、站点所在的寻呼集合的寻呼集合标识。
其中,所述唤醒标识的取值根据以下参数进行取值:站点是否移动、站点移动范围的大小、站点的类别、站点所在的BSS/ESS/寻呼集合/整个网络内站点的数量;本实施例中,以寻呼集合管理实***于AC为例,寻呼集合管理实体触发寻呼集合内的AP发送第一无线信号,所述第一无线信号用于唤醒站点。
其中,所述寻呼集合管理实体触发AP发送第一无线信号的方式有多种。寻呼集合管理实体可以触发一个寻呼集合内的所有BSS的接入点发送第一无线信号;或者,触发一个寻呼集合内的部分BSS的接入点发送第一无线信号;或者,触发至少两个寻呼集合内的所有BSS的接入点发送第一无线信号;或者,
触发至少两个寻呼集合内的部分BSS的接入点发送第一无线信号。以实施例一中的图1的场景为例,多个寻呼集合配置了一个寻呼集合管理实体,则该寻呼集合管理实体触发AP发送第一无线信号的方式可以包括:
通知某个寻呼集合内的某些BSS的AP发送第一无线信号唤醒某站点,例如是同一个ESS中的所有AP,当这些AP发送第一无线信号在预定时间内没有收到响应帧,AP向寻呼集合管理实体上报唤醒失败,则寻呼集合管理实体可以通知所述寻呼集合内的其他BSS的AP发送第一无线信号,继续唤醒所述站点,或者更换寻呼集合,通知其他寻呼集合中的某些BSS的AP发送第一无线信号,唤醒所述站点,直到收到AP的确认,所述站点已被唤醒。
在上述实施方式中,寻呼集合管理实体采用了分级唤醒的方式,避免大
量AP发送第一无线信号,造成信道拥塞,寻呼集合管理实体可以根据之前收集到的站点(STA)的位置信息,判断触发哪些寻呼集合内的哪些AP发送第一无线信号。
或者,寻呼集合管理实体通知某个寻呼集合内的所有AP发送第一无线信号唤醒某站点,当这些AP发送第一无线信号在预定时间内没有收到响应帧,AP向寻呼集合管理实体上报唤醒失败,则寻呼集合管理实体更换寻呼集合,通知其他寻呼集合中的所有AP发送第一无线信号,唤醒所述站点,直到收到AP的确认,所述站点已被唤醒。
在上述实施方式中,寻呼集合管理实体内没有站点(STA)的位置信息,则每次唤醒都是在一个寻呼集合内所有的AP下进行的。
在上述实施方式中,多个AP发送第一无线信号的方式,可以竞争发送,也可以采用下行多用户的并行发送方式,即将多个AP的第一无线信号采用下行链路多用户(DL-MU,Down Link Multi-User)多输入多输出(MIMO,Multiple-Input Multiple-Output)或者下行链路(DL,Down Link)正交频分多址(OFDMA,Orthogonal Frequency Division Multiple Access)的方式进行发送。寻呼集合管理实体负责多个AP之间的时频域同步。
对于实施例一中的图2的场景,每个寻呼集合都有各自的寻呼集合管理实体,则对于每个寻呼集合管理实体触发AP发送第一无线信号的方式可以包括:
通知该寻呼集合内的某些BSS的AP发送第一无线信号唤醒某站点,例如是同一个ESS中的所有AP,当这些AP发送第一无线信号在预定时间内没有收到响应帧,AP向寻呼集合管理实体上报唤醒失败,则寻呼集合管理实体可以通知该寻呼集合内的其他BSS的AP发送第一无线信号,继续唤醒所述站点。寻呼集合管理实体需要上层中心节点通知其他寻呼集合管理实体触发在其他集合中的BSS的AP发送第一无线信号,唤醒所述站点,直到收到来自某个AP的确认,所述站点已被唤醒。
在上述实施方式中,寻呼集合管理实体根据之前收集到的STA的位置信息,判断触发寻呼集合内的哪些AP发送第一无线信号。
或者,寻呼集合管理实体通知寻呼集合内的所有AP发送第一无线信号唤醒某站点,当这些AP发送第一无线信号在预定时间内没有收到响应帧,AP向寻呼集合管理实体上报唤醒失败,则寻呼集合管理实体通过上层中心节点通知其他寻呼集合的寻呼集合管理实体,触发其他寻寻呼集合管理实体中的所有AP发送第一无线信号,唤醒所述站点,直到收到某个AP的确认,所述站点已被唤醒。
在上述实施方式中,寻呼集合管理实体没有STA的位置信息,则每次唤醒都是在一个寻呼集合内所有的AP下进行的。
在上述实施方式中,属于多个寻呼集合的BSS能够和多个寻呼集合管理实体进行通信,因此,当一个在寻呼集合内唤醒某站点(STA)失败时,该寻呼集合的寻呼集合管理实体可以通过属于多个寻呼集合的那个BSS通知其他寻呼集合管理实体继续进行站点(STA)唤醒。在上述例子中,多个AP发送第一无线信号的方式,可以竞争发送,也可以采用下行多用户的并行发送方式,即将多个AP的第一无线信号采用DL-MU MIMO或者DLOFDMA的方式进行发送。寻呼集合管理实体负责多个AP之间的时频域同步。
也就是说,所述寻呼集合管理实体触发一个寻呼集合内的所有BSS的接入点发送第一无线信号;或者,所述寻呼集合管理实体触发一个寻呼集合内的部分BSS的接入点发送第一无线信号;或者,所述寻呼集合管理实体触发至少两个寻呼集合内的所有BSS的接入点发送第一无线信号;所述寻呼集合管理实体触发至少两个寻呼集合内的部分BSS的接入点发送第一无线信号。
对于站点(STA),如果接收到多个第一无线信号,其中都携带了自身的唤醒标识,则站点(STA)可以选择接收信号强度最强的第一无线信号对应的发送AP作为与进行通信的AP,而忽略其他第一无线信号对应的AP。其中,所述站点(STA)可以是与AP关联或者未关联的站点。
其中,AP可以事先通知STA接收第一无线信号的信道。目前同一ESS内的BSS可能具有不同的运行信道或主信道,因此可以为一个ESS或一个寻呼集合内的BSS固定至少一个发送第一无线信号的信道并通知给站点,
让站点能够减少扫描信道的时间并可以尽快接收到第一无线信号。该信道的带宽可以小于STA和AP正常数据传输的带宽。
采用本发明实施例的设备唤醒方法和设备,针对无线设备发生移动进而导致的无法被唤醒的情况,使得无线设备在移动过程中能够监测网络变化,并将自身的位置信息上报给网络,从而达到处于省电模式时能够准确地被唤醒的效果,在省电的同时,节约了空口资源。
实施例三
本发明实施例还提供了一种设备唤醒方法。本实施例可以为站点位置信息上报过程。图4为本发明实施例的设备唤醒方法的第二种流程示意图;如图4所示,所述方法包括:
步骤201:接入点发送携带有识别信息的第二无线信号;所述第二无线信号用于站点检测自身所处以下网络环境的至少之一是否发生改变:寻呼集合、BSS、ESS。
步骤202:站点接收第二无线信号,根据所述第二无线信号判断自身所处的网络环境;所述网络环境包括以下网络环境的至少之一:寻呼集合、基本服务集BSS、扩展服务器集ESS。
本实施例中,处于寻呼集合内的AP,采用周期或者事件触发的方式,以组播或广播的形式发送第二无线信号。第二无线信号类似于***信息,但仅携带识别信息,用于令处于其覆盖范围内的STA识别当前自身位置的变化情况。
在所述第二无线信号中,所述识别信息包括以下信息的至少之一:所述接入点的接入点标识信息或所述接入点的部分接入点标识信息、所述接入点所属的ESS标识信息或所述接入点所属的部分ESS标识信息、所述接入点所属的寻呼集合的寻呼集合标识信息或所述接入点所属的寻呼集合的部分寻呼集合标识信息。其中,携带的识别信息可以为以下信息的至少之一:
AP的BSSID,或者AP的BSS color;或者AP的部分BSSID,例如完整48比特的BSSID的高N个字节(N为正整数),或者是接入点的BSSID经某种运算获得的值,该值可用于识别一个AP;
AP所属的ESS的ESSID,或者AP所属的部分ESSID,例如ESSID的高M个字节(M为正整数),或者是AP所属的ESS的ESSID经某种运算获得的值,该值可以识别一个ESS;
AP所属的寻呼集合的寻呼集合标识,或部分寻呼集合标识,例如寻呼集合标识的部分字节,或寻呼标识经过运算得到的值,该值可以识别一个寻呼集合。
本实施例中,STA在与一个AP关联时,获取了该AP的BSSID,该AP所在的ESS的ESSID,以及该AP所在的寻呼集合的标识信息,STA将这些信息保存在本地。每当收到一个第二无线信号时,STA将其中的识别信息与本地保存的信息进行对比,若有参数发生了改变,STA可以判断自己所处的BSS、ESS、寻呼集合中的哪些发生了变化。例如,根据参数的对比结果进行判断,STA可能移出了之前关联的BSS,但仍处于原ESS和寻呼集合当中;或者,STA移出了原BSS和ESS,但仍处于原寻呼集合当中;或者,STA移出了原寻呼集合。
其中,STA在移动过程中,根据最近一次收到的第二无线信号,不断更新本地保存的识别信息,用于判断自身位置的变化情况。
当STA识别到自己所处的BSS、ESS或者寻呼集合改变了,STA上报给AP。上报策略可以是以下其中之一:
当站点(STA)检测到自身所处的BSS变更,站点发送第三无线信号,上报自身位置;
当站点(STA)检测到自身所处的ESS变更,站点发送第三无线信号,上报自身位置;
当站点(STA)检测到自身所处的寻呼集合变更,站点发送第三无线信号,上报自身位置。
其中,站点(STA)选择的第三无线信号的接收方AP可以是未与其关联的AP,例如STA进入了一个新的AP的覆盖范围,STA发送第三无线信号给该AP,上报自身位置。STA也可以不指定第三无线信号的接收方AP,即发送一个接收地址为广播地址的第三无线信号,则任意AP收到该信号,
都可以上报给网络侧。
其中,所述第三无线信号中携带了能够识别STA的站点标识信息,例如是STA的48比特MAC地址,STA的关联标识AID,或者是部分AID,或者当STA的唤醒标识表征整网唯一性时,是STA的唤醒标识等。第三无线信号可以仅是一个没有MAC层负载的空数据包(NDP,Null Data Packet)帧。
AP接收到一个STA发送的第三无线信号,则会保存其中的站点标识信息,并将此信息上报给AP所属的寻呼集合管理实体,寻呼集合管理实体进行进一步操作和决策,包括:更新STA当前所在的BSS、ESS、寻呼集合;如果是新进入一个寻呼集合的STA,为该STA重新分配唤醒标识,并触发AP将重新分配的唤醒标识发送给STA,或者触发AP为该STA重新分配唤醒标识。
STA发送第三无线信号的方法较为灵活,由于当前STA处于省电模式,STA可以使用STA内置的省电模块接收和解析第二无线信号,当需要时,使用省电模块发送第三无线信号。接收第二无线信号,发送第三无线信号时,站点除省电模块以外的其他模块处于关闭状态。或者,STA可以使用其他具备通信能力的模块,以低功耗,低速率的方式发送第三无线信号。
AP可在发送第二无线信号和/或接收第三无线信号之前,通知STA接收所述第二无线信号和/或发送所述第三无线信号使用的至少一个信道。目前ESS内的BSS可能具有不同的运行信道或主信道,因此可以为一个ESS或一个寻呼集合内的BSS固定至少一个发送第二无线信号的信道和/或发送第三无线信号的信道并通知给站点上述信道的带宽可以小于STA和AP正常数据传输的带宽。
采用本发明实施例的设备唤醒方法和设备,针对无线设备发生移动进而导致的无法被唤醒的情况,使得无线设备在移动过程中能够监测网络变化,并将自身的位置信息上报给网络,从而达到处于省电模式时能够准确地被唤醒的效果,在省电的同时,节约了空口资源。
实施例四
本发明实施例还提供了一种设备唤醒方法,本实施例为唤醒标识的分配与重分配过程。图5为本发明实施例的设备唤醒方法的第三种流程示意图;如图5所示,所述方法包括:
步骤301:站点接收接入点发送的第一无线信号;所述第一无线信号中可能携带所述站点的唤醒标识。
本实施例中,当STA处于一个AP的覆盖范围内时,STA完成与所述AP的关联认证,STA这时被称为接入所述AP。STA在关联过程中,由AP为其分配一个关联标识AID,该AID在该BSS内是唯一的。STA可能进入省电模式,因此为该STA分配唤醒标识。
唤醒标识可以在STA关联AP之前分配给STA,或者关联AP过程中分配给STA,也可以在STA发起进入省电模式的过程中分配给STA。分配唤醒标识的实体可以是寻呼集合管理实体,也可以是接入点,还可以是其他网络实体。所述唤醒标识还可以是站点根据下面描述的取值方式,经自身运算得到。所述唤醒标识在特定范围内具有唯一性,所述特定范围包括:在STA关联BSS内唯一,或者在BSS所在的ESS内唯一,或者是在BSS所属的寻呼集合内唯一,或者是在整个网络内是唯一的。所述唤醒标识的取值可以考虑以下因素:STA是否移动,移动范围的大小,STA的类别,STA所在的BSS/ESS/寻呼集合/整个网络内站点的数量。
所述唤醒标识的取值根据以下参数的至少之一按运算获得:以STA的MAC地址、站点的关联标识(AID),STA所在的BSS的BSSID,STA所在的ESS的ESSID,站点所在的寻呼集合的寻呼集合标识。运算可以是截取、级联、哈希(HASH)、逻辑运算等等。其中,截取运算包括,截取上述MAC地址、AID、BSSID、ESSID,寻呼集合标识的部分字节或比特;级联运算包括:将上述MAC地址、AID、BSSID、ESSID,寻呼集合标识中的至少一个级联得到,或者将上述MAC地址、AID、BSSID、ESSID,寻呼集合标识中的至少一个首先进行截取,然后进行级联得到;HASH运算是将上述MAC地址、AID、BSSID、ESSID,寻呼集合标识中的至少一个执行HASH运算,或者首先进行截取,再进行HASH;逻辑运算包括:以上述MAC地址、AID、BSSID、ESSID,寻呼集合标识中的至少一个为参数进行“与”、
“或”、“非”等运算,或者首先进行截取,再进行逻辑运算。如果AP支持多BSS属性,则BSSID可以选择AP支持的BSSID集合中的任意一个。
综合以上因素,唤醒标识的取值方式有多种方案,举例如下:
如果STA是一个不具备移动能力的设备,使用STA的AID作为其唤醒标识,唤醒标识在BSS内是唯一的;
如果STA仅在ESS内移动,使用STA的AID与STA所在的BSS的BSSID进行某种运算产生STA的唤醒标识,可以是STA自身运算得到,或者是由AP、ESS管理实体,或寻呼集合管理实体统一分配,保证该唤醒标识在ESS内唯一;
或者,使用STA的AID、与STA所在的BSSID、ESSID和/或寻呼集合标识经运算产生STA的唤醒标识,可以是STA自身运算得到,或者由AP、ESS管理实体、或寻呼集合管理实体统一分配,所述唤醒标识在寻呼集合内唯一;
或者,寻呼集合管理实体或者其他网络实体进行整网统一分配唤醒标识,保证所述唤醒标识在整个网络内唯一,其他网络实体可以是接入网络队列协议(ANQP,Access Network Query Protocol)或通用应用服务器(GAS,Generic Application Server);
所述唤醒标识可以由多级字段组成,每级字段具有若干字节或比特,例如,如果能够获知STA的类别,例如STA的设备类型,或者STA的应用类型,或STA所属的运营商,则唤醒标识可以采用设备/应用类型/运营商识别码级联设备编码的取值方式;或者唤醒标识可以使用寻呼集合标识级联站点标识的取值方式;
如果STA所在的BSS中的站点数量很少,可以采用部分AID来作为唤醒标识,如果站点数量增多,则可以采用完整的AID来作为唤醒标识。
以上例子中,STA的唤醒标识如果根据STA是否移动,移动范围的大小,STA的类别,STA所在的BSS/ESS/寻呼集合/整个网络内站点的数量是可变长标识,比如在某些情况下唤醒标识可能使用部分AID,在某些情况下可能使用完整AID,则在所有包含唤醒标识的信号中,例如第一无线信号、
第四无线信号等信号中指示所使用的标识的长短,可以是一个长短指示位,0表示采用短标识,1表示采用长标识。STA读取长短指示位,则知道当前信号中的唤醒标识应该读取多少位进行解析。
AP实现在ESS内统一分配唤醒标识的方式,可以包括:由ESS管理实体统一为ESS内的各AP预分配地址空间,再由AP将预分配地址空间中的值分配给STA;
AP或ESS管理实体实现在整网内统一分配唤醒标识的方式,可以包括:由寻呼集合管理实体为各AP或ESS管理实体预分配地址空间,再由AP将预分配地址空间中的值分配给STA。
如果网络侧判断一个STA移出BSS/ESS/寻呼集合,则允许将该STA使用的唤醒标识分配给其他STA。判断的依据可以是根据STA上报的第三无线信号,或者网络侧设置定时器,一定时间内没有收到STA的任何信号,认为STA移出。
一旦寻呼集合管理实体或其他网络实体为STA重新分配了唤醒标识,则将新标识发送给AP,经由AP发送至STA。AP可以在收到STA发送第三无线信号后,通过第四无线信号发送重分配的唤醒标识。或者,AP可以单独发送第四无线信号,为STA更新唤醒标识。AP还可以在第一无线信号中携带STA正在使用的唤醒标识和重新分配的唤醒标识,STA收到后,进行自身唤醒标识的更新。STA接收第四无线信号和第一无线信号可以使用STA内置的省电模块,接收第四无线信号和第一无线信号时,站点除省电模块以外的其他模块处于关闭状态。AP可以在发送第四无线信号之前,通知STA接收第四无线信号的至少一个信道。可以为一个ESS或一个寻呼集合内的BSS固定至少一个发送第四无线信号的信道并通知给站点,该信道的带宽可以小于STA和AP正常数据传输的带宽。采用本发明实施例的设备唤醒方法和设备,针对无线设备发生移动进而导致的无法被唤醒的情况,使得无线设备在移动过程中能够监测网络变化,并将自身的位置信息上报给网络,从而达到处于省电模式时能够准确地被唤醒的效果,在省电的同时,节约了空口资源。
实施例五
本实施例描述AP的唤醒标识的分配方法。由于AP本身也是一个站点,因此在一些场景下,AP也可以进入省电模式,当STA有数据要发送给AP时,STA可以发送第一无线信号来唤醒AP,此时,第一无线信号中携带AP的唤醒标识。
AP的唤醒标识可以在STA关联到AP之后通知STA,也可以在STA未关联时通过解析AP发送的任一携带AP唤醒标识的信号来获得,或者在AP进入省电模式时通知STA。
为AP分配唤醒标识的实体可以是寻呼集合管理实体,ESS管理实体、也可以是其他网络实体。所述唤醒标识还可以是AP根据下面描述的取值方式,经自身运算得到。所述唤醒标识在特定范围内具有唯一性,所述特定范围包括:在AP所属的ESS内唯一,在AP所属的寻呼集合内唯一,或者是在整个网络内是唯一的。
所述唤醒标识的取值可以考虑以下因素:AP是否移动,移动范围的大小,AP的类别,AP所在的ESS/寻呼集合/整个网络内AP或中继节点的数量。
所述唤醒标识的取值根据以下参数的至少之一按运算获得:AP的MAC地址(即BSSID)、AP所在的ESS的ESSID,AP所在的寻呼集合的寻呼集合标识,AP使用的特殊AID值(如AID 0或AID 2047)。运算可以是截取、级联、哈希(HASH)、逻辑运算等等。其中,截取运算包括,截取上述MAC地址、ESSID,寻呼集合标识、AP的AID值的部分字节或比特;级联运算包括:将上述MAC地址、ESSID,寻呼集合标识、AP的AID值中的至少一个级联得到,或者将上述MAC地址、ESSID,寻呼集合标识、AP的AID值中的至少一个首先进行截取,然后进行级联得到;HASH运算是将上述MAC地址、ESSID,寻呼集合标识、AP的AID值中的至少一个执行HASH运算,或者首先进行截取,再进行HASH;逻辑运算包括:以上述MAC地址、ESSID,寻呼集合标识中、AP的AID值的至少一个为参数进行“与”、“或”、“非”等运算,或者首先进行截取,再进行逻辑运算。如果AP支持多BSS属性,则MAC地址可以选择AP支持的BSSID集合中
的任意一个。
AP的唤醒标识可以由多级字段组成,每级字段具有若干字节或比特,例如,如果能够获知AP的类别,例如AP的设备类型,或者AP的应用类型,或AP所属的运营商,则唤醒标识可以采用设备/应用类型/运营商识别码级联设备编码的取值方式;或者唤醒标识可以使用寻呼集合标识级联AP的AID值,或级联AP的(部分)BSSID等取值方式。
实施例六
本发明实施例还提供了一种设备唤醒方法;本实施例是站点(STA)唤醒过程。图6为本发明实施例的设备唤醒方法的第四种流程示意图;如图6所示,所述方法包括:
步骤401:接入点发送第一无线信号;所述第一无线信号用于唤醒与所述接入点关联或未关联的站点。
本实施例中,当有给某个STA的下行数据,而STA处于省电模式时,则AP唤醒所述STA,将数据发送给所述STA。采用上述实施例二中的策略,寻呼集合管理实体触发AP发送第一无线信号,唤醒该站点。
其中,AP将第一无线信号发送至STA,所述第一无线信号中携带STA的唤醒标识,AP可以唤醒与本AP关联的STA,也可以唤醒尚未与本AP关联的STA。AP还可以在第一无线信号中同时携带多个唤醒标识,目的是一次唤醒多个STA。AP还可以将多个携带了多个唤醒标识的第一无线信号采用下行多用户方式发送,这样一次唤醒的STA数量就更多。
第一无线信号中除了唤醒标识,还可以携带一些控制指令,指示收到被唤醒的STA进行相应的动作,即所述第一无线信号用于指示与所述接入点关联或者未关联的站点触发以下操作的至少之一:上报自身位置信息、等待下行数据接收、进行上行数据发送、是否执行网络接入。STA收到包括了自身唤醒标识的第一无线信号,则解析该信号,执行相关操作。
其中,所述控制指令可以包括:请STA发送第三无线信号报告自身位置、等待下行数据接收、进行上行数据发送以及是否执行网络接入等等。如果控制指令表示STA等待下行数据接收,则STA在被唤醒后发送确认帧给
AP,通知AP已被环形,然后等待AP发送下行数据;如果控制指令表示STA进行上行数据发送,则STA将之前缓存中已经准备好的数据发送给AP,或者立即进行数据收集,并将收集的数据发送给AP;如果控制指令表示是否执行网络接入,若指示为“是”时,则STA和AP开始关联认证过程,若指示为“否”时,则表明AP允许STA不执行关联认证就可以直接与AP进行数据收发。
由于当尝试唤醒一个STA时,多个AP都在发送第一无线信号,可能STA先后收到多个携带自身唤醒标识的第一无线信号,这时,STA选择接收信号强度最强的AP,并执行所述AP发送的第一无线信号中指示的操作。
本实施例中,STA进入省电模式,就开始监听以下无线信号的至少之一:第一无线信号、第二无线信号、第四无线信号,STA可以使用自身内置的省电模块接收和解析上述第一无线信号、第二无线信号或第四无线信号。而第一无线信号中的指令,可能需要省电模块之外的其他模块来完成。
本实施例中,STA接收到第一无线信号或者第四无线信号为自己重分配了唤醒标识,STA要更新本地保存的自己的唤醒标识。
采用本发明实施例的设备唤醒方法和设备,针对无线设备发生移动进而导致的无法被唤醒的情况,使得无线设备在移动过程中能够监测网络变化,并将自身的位置信息上报给网络,从而达到处于省电模式时能够准确地被唤醒的效果,在省电的同时,节约了空口资源。
实施例七
本实施例还提供了一种设备唤醒方法。本实施例针对寻呼集合管理实体、接入点以及站点的完整流程进行描述,包括以下内容:
寻呼集合管理实体配置一个ESS即是一个寻呼集合,所有寻呼集合由统一寻呼集合管理实体进行管理,每个ESS下有多个BSS,寻呼集合标识即ESSID。该寻呼集合管理实体为每个寻呼集合内的每个AP下的进入省电模式的站点统一分配唤醒标识,该唤醒标识在该寻呼集合内是唯一的。
