Description

一种设备唤醒方法和设备Device wake-up method and device

技术领域Technical field

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。The present application relates to, but is not limited to, a wireless communication technology, and more particularly to a device wake-up method and device.

背景技术Background technique

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。At present, the Internet of Things industry is developing rapidly. A large number of IoT devices are connected to the network and connected to each other through wired or wireless means, including intelligent transportation, environmental protection, government work, public safety, safe home, intelligent fire protection, industrial monitoring, and elderly care. Personal health, water monitoring, food traceability and many other areas. The number of IoT devices involved in IoT applications is huge and can be called massive terminals. Most of these terminals work on battery power. In most application scenarios, such as water quality monitoring, environmental monitoring and industrial monitoring, the installation location of the equipment is not easy to detect and repair at any time, and to replace the battery, in other scenarios, such as intelligent transportation, power meter reading, service providers It is also hoped that once the device is installed, it can be replaced for several months or even years without replacing the battery, which requires the IoT device to have a high-performance power-saving mechanism.

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。Among the various power-saving mechanisms, one of the methods is to add a power-saving module to the IoT device with wireless communication capability. The working principle of the power-saving module is as follows: When the power-saving module is turned on, the device can shut down other modules. For example, the sensor module, the microprocessor module, the memory module, the wireless communication module, and the like, only the power saving module is reserved, and the working state may be referred to as a power saving state or a power saving mode. The power-saving module consumes very little power during operation, generally at the microwatt level. The power saving module needs to monitor whether there is a wake-up signal sent to itself. Once received, it triggers other modules to work according to the request of the wake-up signal, such as turning on the micro-processing module, turning on the wireless communication module, etc., which may be called wake-up. process.

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。The above-mentioned working mode is described by taking the common devices in the wireless network: an access point (AP, Access Point) and a non-access site (STA, non-AP STA) as an example. An AP establishes a basic service set (BSS), and the STA is a wireless device associated with the AP. If a power saving module is added to the STA, the STA can only reserve the power saving module without the service data. Work to receive wake-up signals. After the AP needs to send downlink data to the STA, the AP first sends a wake-up signal to the STA. The STA's power-saving module receives the wake-up signal and confirms. The wake-up signal is sent to itself, and according to the content of the wake-up signal, other modules are turned on, and related operations are performed, for example, receiving downlink data from the AP.

发明概述Summary of invention

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。The following is an overview of the topics detailed in this document. This Summary is not intended to limit the scope of the claims.

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。In some cases, when the STA is in the power saving mode that only keeps the power saving module working, the STA may move, thereby removing the coverage of the original associated AP. For example, in the cargo scenario, each box of goods is installed with wireless tracking equipment. When the goods enter the logistics link, they will soon be removed from the coverage of the original AP. At this time, the possible situation is that the original AP cannot know the location of the STA. When the network needs to send data to the STA, the original AP cannot wake up the corresponding device when the wake-up signal is sent. The original AP does not respond. In this case, the wake-up signal may be retransmitted multiple times, resulting in waste of air interface resources, and is not conducive to the AP power saving. On the other hand, the STA enters the coverage of other APs, and other APs are not notified, and other APs are not responsible for waking up the STA, which may result in the STA being unable to be woken up.

详述Detailed

下面结合附图对本发明的实施例作进一步详细的说明。The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

实施例一 Embodiment 1

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。In a wireless local area network, an AP establishes a BSS. The BSS has a certain coverage according to the AP's transmit power and antenna configuration. The station in the WLAN is within the coverage of a BSS. If the station enters the power-saving mode. In order to achieve the effect of waking up the site, several paging sets are established in this embodiment. Each paging set includes a number of BSSs and may include at least one BSS. Moreover, since a plurality of BSSs can form an extended service set (ESS), a plurality of BSSs in each paging set can also form an ESS or form a plurality of ESSs. Of course, the ESSs may not be formed. A BSS can also belong to multiple paging sets. The number of BSSs in the paging set needs to be set properly, and the premise of guarantee coverage If the number of APs sent by the paging message is too large, the channel collision is intensified, and the paging collision is not detected.

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：FIG. 1 is a schematic diagram of a network topology structure of a paging set according to an embodiment of the present invention; an example of the foregoing paging set may be as shown in FIG. 1. The paging set 1 includes three BSSs: BSS1, BSS2, and BSS8, and BSS1, BSS2, and BSS8 constitute one ESS1. The paging set 2 includes four BSSs: BSS3, BSS4, BSS5, and BSS6, wherein BSS3 and BSS4 constitute ESS2, and BSS5 and BSS6 constitute ESS3. Paging Set 3 contains two BSSs: BSS7 and BSS8, which do not form an ESS. It can be seen that BSS8 belongs to two paging sets: paging set 1 and paging set 3. In FIG. 1, a paging set management entity is configured for a plurality of paging sets, and the paging set management entity is configured to manage paging set 1, paging set 2, and paging set 3.

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。At least one AP within the at least one paging set is triggered to send a first wireless signal carrying at least one wake-up identifier to wake up the station. The awakened site can be a site that is associated with or not associated with the AP.

实施例二 Embodiment 2

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：The embodiment of the invention provides a device wake-up method. This embodiment may be a paging policy of the paging set management entity. FIG. 3 is a first schematic flowchart of a method for waking up a device according to an embodiment of the present invention; as shown in FIG. 3, the method includes:

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。Step 101: The paging set management entity triggers at least one access point in the at least one paging set to send a first wireless signal; the first wireless signal is used to wake up a site associated with or not associated with the access point; The paging management entity manages at least one paging set. Wherein each paging set includes at least one BSS, and at least one BSS in each paging set may be composed to One less ESS, or the BSS in the paging set does not form an ESS; the paging set management entity allocates or reallocates a wakeup identity for a site associated with or not associated with the access point within the paging set; The identity is unique within a particular scope; the specific scope includes: a basic service set BSS, an extended server set ESS, a paging set, or an entire network.

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。In this embodiment, the value of the wake-up identifier is obtained according to at least one of the following parameters: a media access control MAC address of the site, an associated identifier of the site, a basic service set BSS identifier where the site is located, and an ESS identifier of the site where the site is located. The paging set identifier of the paging set where the site is located.

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。The value of the wake-up identifier is determined according to the following parameters: whether the site moves, the size of the site moving range, the category of the site, the BSS/ESS/paging set where the site is located, or the number of sites in the entire network; For example, in the case that the paging set management entity is located in the AC, the paging set management entity triggers the AP in the paging set to send the first wireless signal, where the first wireless signal is used to wake up the station.

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，The paging set management entity triggers the AP to send the first wireless signal in multiple manners. The paging set management entity may trigger an access point of all BSSs in a paging set to send a first wireless signal; or an access point that triggers a partial BSS in a paging set to send a first wireless signal; or, trigger at least The access points of all BSSs in the two paging sets send the first wireless signal; or,

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：An access point that triggers a portion of the BSS within at least two paging sets transmits a first wireless signal. For example, in the scenario of FIG. 1 in the first embodiment, a plurality of paging sets are configured with a paging set management entity, and the manner in which the paging set management entity triggers the AP to send the first wireless signal may include:

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。Notifying the APs of some BSSs in a certain paging set to send a first wireless signal to wake up a certain station, for example, all APs in the same ESS. When these APs send the first wireless signal, the response frame is not received within a predetermined time. The AP reports the wakeup failure to the paging set management entity, and the paging set management entity may notify the APs of other BSSs in the paging set to send the first wireless signal, continue to wake up the site, or replace the paging set to notify other The APs of some of the BSSs in the paging set send a first radio signal, waking up the station, until the acknowledgment of the AP is received, the station has been woken up.

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。In the above embodiment, the paging set management entity adopts a hierarchical wake-up manner to avoid large The AP transmits the first wireless signal, causing channel congestion. The paging set management entity can determine which APs in the paging set are triggered to send the first wireless signal according to the location information of the previously collected station (STA).

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。Alternatively, the paging set management entity notifies all APs in a certain paging set to send the first wireless signal to wake up a certain station. When the AP sends the first wireless signal and does not receive the response frame within a predetermined time, the AP manages the paging set. If the entity fails to report the wakeup, the paging set management entity replaces the paging set, notifies all APs in the other paging set to send the first wireless signal, wakes up the site, and receives the acknowledgement of the AP, and the site has been woken up.

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。In the above embodiment, if there is no location information of the station (STA) in the paging set management entity, each wake-up is performed under all APs in one paging set.

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。In the above embodiment, the manner in which the plurality of APs transmit the first wireless signal may be contend for transmission, or may be a parallel multi-user parallel transmission mode, that is, the first wireless signal of multiple APs adopts downlink multi-user (DL- MU, Down Link Multi-User) MIMO (Multiple-Input Multiple-Output) or DL (Down Link) Orthogonal Frequency Division Multiple Access (OFDMA) send. The paging set management entity is responsible for time-frequency domain synchronization between multiple APs.

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：For the scenario of FIG. 2 in the first embodiment, each paging set has a respective paging set management entity, and the manner in which each paging set management entity triggers the AP to send the first wireless signal may include:

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。Notifying the APs of some BSSs in the paging set to send a first wireless signal to wake up a certain station, for example, all APs in the same ESS. When these APs send the first wireless signal, the response frame is not received within a predetermined time, the AP If the wakeup failure is reported to the paging set management entity, the paging set management entity may notify the APs of other BSSs in the paging set to send the first wireless signal, and continue to wake up the site. The paging set management entity needs the upper central node to notify other paging set management entities to trigger the APs of the BSSs in other sets to send the first wireless signal, wake up the site until receiving confirmation from an AP that the site has Was awakened.

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。 In the foregoing embodiment, the paging set management entity determines, according to the previously collected location information of the STA, which APs in the triggered paging set send the first wireless signal.

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。Alternatively, the paging set management entity notifies all APs in the paging set to send the first wireless signal to wake up a certain station. When the AP sends the first wireless signal and does not receive the response frame within a predetermined time, the AP reports to the paging set management entity. If the wakeup fails, the paging set management entity notifies the paging set management entity of the other paging set by the upper central node, triggers all APs in the other paging set management entity to send the first wireless signal, and wakes up the site until receiving. Upon confirmation of an AP, the site has been woken up.

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。In the above embodiment, the paging set management entity does not have the location information of the STA, and each wake-up is performed under all APs in one paging set.

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。In the above embodiment, the BSS belonging to the plurality of paging sets can communicate with the plurality of paging set management entities, and therefore, when a certain station (STA) fails to be awakened within the paging set, the paging set is searched. The call set management entity may notify the other paging set management entity to continue the station (STA) wakeup by the BSS belonging to the plurality of paging sets. In the above example, the manner in which the plurality of APs transmit the first wireless signal may be contending for transmission, or may be the parallel transmission mode of the downlink multi-user, that is, the first wireless signal of multiple APs is performed by using DL-MU MIMO or DLADMA. send. The paging set management entity is responsible for time-frequency domain synchronization between multiple APs.

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。That is, the paging set management entity triggers an access point of all BSSs in a paging set to send a first wireless signal; or the paging set management entity triggers a partial BSS connection in a paging set. Transmitting a first wireless signal; or the paging set management entity triggers an access point of all BSSs in at least two paging sets to send a first wireless signal; the paging set management entity triggers at least two seeks The access point of the partial BSS within the call set transmits the first wireless signal.

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。For a station (STA), if a plurality of first wireless signals are received, each of which carries its own wake-up identifier, the station (STA) may select to send the corresponding AP corresponding to the first wireless signal with the strongest signal strength as the communication. AP, while ignoring APs corresponding to other first wireless signals. The site (STA) may be a site associated with or not associated with the AP.

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。The AP may notify the STA in advance to receive the channel of the first wireless signal. Currently, the BSSs in the same ESS may have different operating channels or primary channels, so that at least one channel that transmits the first wireless signal may be fixed to an ESS or a BSS in a paging set and notified to the station. Allows the station to reduce the time to scan the channel and receive the first wireless signal as quickly as possible. The bandwidth of the channel can be smaller than the bandwidth of the normal data transmission of the STA and the AP.

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：The embodiment of the invention further provides a device wake-up method. This embodiment may be a site location information reporting process. FIG. 4 is a schematic diagram of a second process of a device wake-up method according to an embodiment of the present invention; as shown in FIG. 4, the method includes:

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。Step 201: The access point sends a second wireless signal carrying the identification information. The second wireless signal is used by the station to detect whether at least one of the following network environments is changed: a paging set, a BSS, and an 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。Step 202: The station receives the second wireless signal, and determines, according to the second wireless signal, the network environment in which the network is located. The network environment includes at least one of the following network environments: a paging set, a basic service set BSS, and an extended server set. 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。In this embodiment, the AP in the paging set sends the second wireless signal in the form of multicast or broadcast in a periodic or event triggered manner. The second wireless signal is similar to system information, but only carries identification information for the STAs within its coverage to recognize changes in the current location.

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：In the second wireless signal, the identification information includes at least one of: access point identification information of the access point or partial access point identification information of the access point, the access The ESS identification information to which the point belongs or the partial ESS identification information to which the access point belongs, the paging set identification information of the paging set to which the access point belongs, or the partial paging of the paging set to which the access point belongs Collection identification information. The carrying identification information may be at least one of the following information:

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； The BSSID of the AP, or the BSS color of the AP; or the partial BSSID of the AP, such as the high N bytes of the complete 48-bit BSSID (N is a positive integer), or the value obtained by some operation of the BSSID of the access point, This value can be used to identify an 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；The ESSID of the ESS to which the AP belongs, or the partial ESSID to which the AP belongs, such as the high M bytes of the ESSID (M is a positive integer), or the value obtained by some operation of the ESSID of the ESS to which the AP belongs. This value can identify one. 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。The paging set identifier of the paging set to which the AP belongs, or the partial paging set identifier, such as a partial byte of the paging set identifier, or a calculated value of the paging identifier, which value identifies a paging set.

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。In this embodiment, when the STA is associated with an AP, the STA obtains the BSSID of the AP, the ESSID of the ESS where the AP is located, and the identifier information of the paging set where the AP is located, and the STA saves the information locally. Whenever a second wireless signal is received, the STA compares the identification information with the locally stored information. If the parameter changes, the STA can determine which of the BSS, ESS, and paging set it is in. Change. For example, based on the comparison result of the parameters, the STA may move out of the previously associated BSS, but still in the original ESS and paging set; or, the STA moves out of the original BSS and ESS, but is still in the original paging set; or The STA moves out of the original paging set.

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。The STA continuously updates the locally saved identification information according to the second wireless signal received last time during the moving process, and is used to determine the change of the position.

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：When the STA recognizes that the BSS, ESS, or paging set it is in is changed, the STA reports to the AP. The escalation strategy can be one of the following:

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；When the station (STA) detects the change of the BSS in which it is located, the station sends a third wireless signal and reports its own location;

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；When the station (STA) detects the change of the ESS in which it is located, the station sends a third wireless signal and reports its own location;

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。When the station (STA) detects the change of the paging set in which it is located, the station sends a third wireless signal and reports its own location.

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。The receiving AP of the third wireless signal selected by the station (STA) may be an AP that is not associated with the AP. For example, the STA enters the coverage of a new AP, and the STA sends a third wireless signal to the AP to report its location. The STA may also not specify the receiver AP of the third wireless signal, that is, send a third wireless signal whose receiving address is a broadcast address, and then any AP receives the signal. Can be reported to the network side.

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。The third wireless signal carries the station identification information that can identify the STA, such as a 48-bit MAC address of the STA, an association identifier AID of the STA, or a partial AID, or the unique identifier of the STA when the wake-up identifier of the STA is used. When it is, it is the wake-up flag of the STA. The third wireless signal may be only one null data packet (NDP) frame without MAC layer loading.

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。After receiving the third wireless signal sent by the STA, the AP saves the site identification information and reports the information to the paging set management entity to which the AP belongs. The paging collection management entity performs further operations and decisions, including: The current BSS, ESS, and paging set of the STA; if it is a new STA that enters a paging set, the AP re-allocates the wake-up identifier to the STA, and triggers the AP to send the re-assigned wake-up identifier to the STA, or triggers the AP as the STA. Reassign the wakeup ID.

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。The method for the STA to send the third wireless signal is flexible. Because the current STA is in the power saving mode, the STA can receive and parse the second wireless signal by using the power saving module built in the STA, and use the power saving module to send the third wireless signal when needed. When the second wireless signal is received and the third wireless signal is transmitted, the other modules except the power saving module are in the off state. Alternatively, the STA may use other communication capable modules to transmit the third wireless signal in a low power, low rate manner.

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。The AP may notify the STA to receive the second wireless signal and/or transmit at least one channel used by the third wireless signal before transmitting the second wireless signal and/or receiving the third wireless signal. The BSS in the current ESS may have different operating channels or primary channels, so that at least one channel for transmitting the second wireless signal and/or the channel for transmitting the third wireless signal may be fixed for one ESS or a BSS within one paging set and notified. The bandwidth of the above channel to the station may be smaller than the bandwidth of the normal data transmission of the STA and the AP.

实施例四 Embodiment 4

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：The embodiment of the invention further provides a device wake-up method, which is a process for allocating and reallocating wake-up identifiers. FIG. 5 is a schematic diagram of a third process of a device wake-up method according to an embodiment of the present invention; as shown in FIG. 5, the method includes:

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。Step 301: The station receives the first wireless signal sent by the access point, where the first wireless signal may carry the wake-up identifier of the site.

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。In this embodiment, when the STA is in the coverage of an AP, the STA completes the association authentication with the AP, and the STA is referred to as accessing the AP at this time. During the association process, the STA assigns an association identifier AID to the AP, and the AID is unique within the BSS. The STA may enter a power saving mode, so the STA is assigned a wakeup identity.

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。The wake-up identifier may be allocated to the STA before the STA associates with the AP, or may be allocated to the STA during the process of the associated AP, or may be allocated to the STA during the process of the STA initiating the power-saving mode. The entity that assigns the wakeup identifier may be a paging set management entity, an access point, or other network entity. The wake-up identifier may also be obtained by the station according to the value method described below. The wake-up identifier is unique within a specific range, including: unique within the STA-associated BSS, or unique within the ESS in which the BSS is located, or unique within the paging set to which the BSS belongs, or throughout It is unique within the network. The value of the wake-up identifier may consider the following factors: whether the STA moves, the size of the mobile range, the category of the STA, the BSS/ESS/paging set where the STA is located, or the number of sites in the entire network.

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。The value of the wake-up identifier is obtained according to at least one of the following parameters: the MAC address of the STA, the association identifier (AID) of the station, the BSSID of the BSS where the STA is located, the ESSID of the ESS where the STA is located, and the location of the ESS where the STA is located. The paging set identifier of the call set. Operations can be truncation, cascading, hashing, logical operations, and so on. The intercepting operation includes: intercepting the MAC address, the AID, the BSSID, the ESSID, and a partial byte or a bit of the paging set identifier; the cascading operation includes: the foregoing MAC address, the AID, the BSSID, the ESSID, and the paging set identifier. At least one of the cascading is obtained, or at least one of the foregoing MAC address, AID, BSSID, ESSID, and paging set identifier is first intercepted, and then cascading is obtained; the HASH operation is to use the MAC address, the AID, the BSSID, and the ESSID. At least one of the paging set identifiers performs a HASH operation, or first performs interception, and then performs HASH; the logical operation includes: performing "AND" with at least one of the foregoing MAC address, AID, BSSID, ESSID, and paging set identifier as parameters. , "or", "non" and other operations, or first intercept, and then logical operations. If the AP supports multiple BSS attributes, the BSSID may select any one of the BSSID sets supported by the AP.

综合以上因素，唤醒标识的取值方式有多种方案，举例如下：Based on the above factors, there are various options for the value of the wake-up identifier. The examples are as follows:

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；If the STA is a device that does not have mobility, the STA's AID is used as its wake-up identifier, and the wake-up identifier is unique within the BSS;

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；If the STA moves only within the ESS, the AID of the STA and the BSSID of the BSS where the STA is located perform some operation to generate the wakeup identifier of the STA, which may be obtained by the STA itself, or managed by the AP, the ESS management entity, or the paging set. The entity is uniformly allocated to ensure that the wakeup identifier is unique within the ESS;

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；Alternatively, using the STA's AID, the BSSID, the ESSID, and/or the paging set identifier of the STA to generate the wake-up identifier of the STA may be obtained by the STA itself, or by the AP, the ESS management entity, or the paging set management entity. Unified allocation, the wake-up identifier is unique within the paging set;

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)；Alternatively, the paging set management entity or other network entity performs the entire network to uniformly allocate the wake-up identifier to ensure that the wake-up identifier is unique within the entire network, and other network entities may be an Access Network Query Protocol (ANQP) or a universal Application Server (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；The wakeup identifier may be composed of a plurality of levels of fields, each of which has a number of bytes or bits. For example, if the category of the STA, such as the device type of the STA, or the application type of the STA, or the operator to which the STA belongs, The wakeup identifier may be a device/application type/operator identifier cascading device coded value manner; or the wakeup identifier may use a paging set to identify a value of the cascading site identifier;

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。If the number of sites in the BSS where the STA is located is small, a partial AID may be used as the wakeup identifier. If the number of sites increases, the complete AID may be used as the wakeup identifier.

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。In the above example, if the STA wake-up identifier is based on whether the STA moves, the size of the mobile range, the category of the STA, the number of sites in the BSS/ESS/paging set/the entire network where the STA is located, the variable length identifier, such as in some In case the wake-up identifier may use a partial AID, in some cases it may be possible to use the full AID, in all signals containing the wake-up identifier, such as the first wireless signal, The length of the identifier used in the signal such as the fourth wireless signal may be a long and short indication bit, where 0 indicates that a short identifier is used, and 1 indicates that a long identifier is used. The STA reads the long and short indication bits, and knows how many bits should be read by the wakeup identifier in the current signal for parsing.

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；The manner in which the AP implements the unified allocation of the wakeup identifier in the ESS may include: the ESS management entity unconditionally allocates an address space for each AP in the ESS, and then the AP allocates the value in the pre-allocated address space to the 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。The method for the AP or the ESS management entity to uniformly allocate the wakeup identifier in the entire network may include: pre-allocating the address space by the paging set management entity for each AP or the ESS management entity, and then assigning the value in the pre-allocated address space by the AP. To the 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。If the network side determines that one STA moves out of the BSS/ESS/Paging Set, the Wakeup ID used by the STA is allowed to be allocated to other STAs. The judgment may be based on the third wireless signal reported by the STA or the timer set on the network side, and no signal is received from the STA within a certain period of time, and the STA is considered to be removed.

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。 Once the paging set management entity or other network entity reassigns the wakeup identity to the STA, the new identity is sent to the AP and sent to the STA via the AP. After receiving the third wireless signal, the AP may send the redistributed wake-up identifier through the fourth wireless signal. Alternatively, the AP may separately send the fourth wireless signal to update the wakeup identifier for the STA. The AP may further carry the wake-up identifier and the re-assigned wake-up identifier that the STA is using in the first wireless signal, and after the STA receives the update, the STA wakes up the identifier. The STA receiving the fourth wireless signal and the first wireless signal may use the power saving module built in the STA. When receiving the fourth wireless signal and the first wireless signal, the other modules except the power saving module are in a closed state. The AP may notify the STA to receive at least one channel of the fourth wireless signal before transmitting the fourth wireless signal. At least one channel for transmitting the fourth wireless signal may be fixed for one ESS or a BSS within a paging set and notified to the station, the bandwidth of the channel may be smaller than the bandwidth of the normal data transmission of the STA and the AP. The method and device for waking up the device in the embodiment of the present invention can be used to monitor the network change during the mobile process, and the location information of the device can be reported to the network. The effect of being able to be awakened accurately when in the power saving mode saves air resources while saving power.

实施例五Embodiment 5

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。This embodiment describes a method for allocating a wakeup identifier of an AP. Since the AP itself is also a site, in some scenarios, the AP can also enter the power saving mode. When the STA has data to send to the AP, the STA can send the first wireless signal to wake up the AP. At this time, in the first wireless signal. Carry the wake-up identifier of the AP.

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。The wake-up identifier of the AP may be notified to the STA after the STA is associated with the AP, or may be obtained by parsing any signal sent by the AP that carries the AP wake-up identifier when the STA is not associated, or notifying the STA when the AP enters the power-saving mode.

实施例六Embodiment 6

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：The embodiment of the invention further provides a device wake-up method; this embodiment is a station (STA) wake-up process. FIG. 6 is a fourth schematic flowchart of a method for waking up a device according to an embodiment of the present invention; as shown in FIG. 6, the method includes:

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。Step 401: The access point sends a first wireless signal, where the first wireless signal is used to wake up a station associated with or not associated with the access point.

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。In this embodiment, when there is downlink data for a certain STA, and the STA is in the power saving mode, the AP wakes up the STA and sends data to the STA. Using the policy in the foregoing embodiment 2, the paging set management entity triggers the AP to send the first wireless signal to wake up the station.

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。The AP sends the first wireless signal to the STA, where the first wireless signal carries the wake-up identifier of the STA, and the AP can wake up the STA associated with the local AP, and can also wake up the STA that has not been associated with the local AP. The AP may also carry multiple wake-up identifiers in the first wireless signal, so as to wake up multiple STAs at a time. The AP may also send multiple first wireless signals carrying multiple wake-up identifiers in a downlink multi-user manner, so that the number of STAs that wake up at one time is more.

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。In addition to the wake-up identifier, the first wireless signal may also carry some control instruction, indicating that the awake STA is received to perform a corresponding action, that is, the first wireless signal is used to indicate a site associated with or not associated with the access point. At least one of the following operations is triggered: reporting own location information, waiting for downlink data reception, performing uplink data transmission, and performing network access. After receiving the first wireless signal including the self-awake identifier, the STA parses the signal and performs related operations.

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。The control command may include: asking the STA to send a third wireless signal to report its own location, waiting for downlink data reception, performing uplink data transmission, and performing network access, and the like. If the control command indicates that the STA waits for downlink data reception, the STA sends an acknowledgement frame after being woken up. The AP notifies the AP that it is ringed, and then waits for the AP to send downlink data. If the control command indicates that the STA performs uplink data transmission, the STA sends the data that has been prepared in the previous buffer to the AP, or immediately collects data, and collects the data. The data is sent to the AP. If the control command indicates whether the network access is performed, if the indication is YES, the STA and the AP start the associated authentication process. If the indication is No, the AP allows the STA to not perform the associated authentication. Data can be sent and received directly with the AP.

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。When multiple APs are transmitting the first wireless signal when attempting to wake up a STA, the STA may receive multiple first wireless signals carrying the self-awake identifier. In this case, the STA selects the AP with the strongest signal strength, and Performing an operation indicated in the first wireless signal transmitted by the AP.

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。In this embodiment, when the STA enters the power saving mode, it starts to monitor at least one of the following wireless signals: the first wireless signal, the second wireless signal, and the fourth wireless signal, and the STA can receive and analyze the above by using the built-in power saving module. The first wireless signal, the second wireless signal, or the fourth wireless signal. The instructions in the first wireless signal may need to be completed by other modules than the power saving module.

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。In this embodiment, the STA receives the first wireless signal or the fourth wireless signal to re-allocate the wake-up identifier for itself, and the STA updates the locally saved own wake-up identifier.

实施例七Example 7

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：This embodiment also provides a device wakeup method. This embodiment describes the complete process of the paging set management entity, the access point, and the site, including the following contents:

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。The paging set management entity configures an ESS to be a paging set. All paging sets are managed by a unified paging set management entity. Each ESS has multiple BSSs, and the paging set identifier is ESSID. The paging set management entity uniformly allocates a wake-up identifier to the station entering the power-saving mode under each AP in each paging set, and the wake-up identifier is unique within the paging set.

STA进入省电模式，开启内置的省电模块，监听第一无线信号和第二无线信号。其中，所述第一无线信号是用来唤醒STA的，所述第二无线信号是用于STA确认自身所处的位置。The STA enters the power saving mode, turns on the built-in power saving module, and monitors the first wireless signal and the second wireless signal. The first wireless signal is used to wake up the STA, and the second wireless signal It is used by the STA to confirm its location.

AP周期性发送第二无线信号，信号中携带的BSSID和ESSID。STA收到第二无线信号，判断自身是否移出BSS。STA一旦判断自身移出BSS，则发送第三无线信号，所述第三无线信号中携带自身的MAC地址，AP接收到所述第三无线信号后，上报给寻呼集合管理实体。STA使用第三无线信号上报自身当前的位置给AP，AP再将信息发送给网络侧，便于网络侧对STA进行定位。对于新进入一个寻呼集合的STA，寻呼集合管理实体为该STA分配新的唤醒标识。The AP periodically sends a second wireless signal, the BSSID and the ESSID carried in the signal. The STA receives the second wireless signal and determines whether it has moved out of the BSS. The STA sends a third wireless signal, and the third wireless signal carries its own MAC address. After receiving the third wireless signal, the AP reports the signal to the paging set management entity. The STA uses the third wireless signal to report its current location to the AP, and the AP sends the information to the network side to facilitate the positioning of the STA by the network. For STAs that newly enter a paging set, the paging set management entity assigns a new wakeup identity to the STA.

另一种情况下，AP周期性发送第二无线信号，信号中携带的BSSID和ESSID。STA收到所述第二无线信号，判断自己是否移出寻呼集合。STA一旦判断自身移出寻呼集合，则发送第三无线信号，所述第三无线信号中携带自己的MAC地址，AP收到后，上报给寻呼集合管理实体，对于新进入一个寻呼集合的STA，为STA分配新的唤醒标识。STA使用第三无线信号上报自身当前的位置给AP，AP再将信息发送给网络侧，便于网络侧对STA进行定位。一旦有数据要发送给STA，寻呼集合管理实体触发寻呼集合内的所有AP发送第一无线信号，尝试唤醒STA。STA收到第一无线信号，其中的唤醒标识与自身唤醒标识匹配，则STA根据第一无线信号中的指示，判断是否要执行网络接入，回复确认帧并等待下行数据，或者发送上行数据。In another case, the AP periodically sends a second wireless signal, the BSSID and the ESSID carried in the signal. The STA receives the second wireless signal and determines whether it has moved out of the paging set. The STA sends a third wireless signal, and the third wireless signal carries its own MAC address, and the AP reports the information to the paging set management entity for entering a paging set. STA, assigns a new wakeup identifier to the STA. The STA uses the third wireless signal to report its current location to the AP, and the AP sends the information to the network side to facilitate the positioning of the STA by the network. Once there is data to be sent to the STA, the paging set management entity triggers all APs in the paging set to send the first wireless signal, attempting to wake up the STA. The STA receives the first wireless signal, where the wake-up identifier matches the self-awake identifier, and the STA determines whether to perform network access according to the indication in the first wireless signal, returns an acknowledgement frame and waits for downlink data, or sends uplink data.
