在无线终端连接到AP后，无线终端与AP之间在大部分时间是不需要进行数据交互的。在无线终端与AP之间没有数据交互的时间内，AP会周期性向无线终端发送信标帧(Beacon)，该Beacon用于指示AP是否有需要发送给无线终端的下行数据。因此，为了节省功耗，无线终端的无线链路一直处于睡眠状态，只有监听到用于指示路由器有需要发送给无线终端的下行数据的Beacon时，无线终端才会唤醒该无线链路，以基于该无线链路与路由器之间进行数据交互。参见图2，无线终端在每个信标帧对应的时间生成接收电流，通过接收电流接收信标帧。由此可见，无线终端中用于无线链路的功耗取决于三个因素，即睡眠状态下无线链路睡眠电流、接收Beacon时的接收电流和Beacon的接收处理时间。After the wireless terminal is connected to the AP, data interaction between the wireless terminal and the AP is not required most of the time. During the time when there is no data interaction between the wireless terminal and the AP, the AP periodically sends a beacon frame (Beacon) to the wireless terminal, and the Beacon is used to indicate whether the AP has downlink data that needs to be sent to the wireless terminal. Therefore, in order to save power consumption, the wireless link of the wireless terminal is always in a sleep state, and the wireless terminal will wake up the wireless link only when it monitors the Beacon indicating that the router has downlink data that needs to be sent to the wireless terminal. Data interaction is performed between the wireless link and the router. Referring to FIG. 2 , the wireless terminal generates a receive current at a time corresponding to each beacon frame, and receives the beacon frame through the receive current. It can be seen that the power consumption used for the wireless link in the wireless terminal depends on three factors, that is, the sleep current of the wireless link in the sleep state, the receiving current when receiving the Beacon, and the receiving processing time of the Beacon.

例如，以信标帧的发送周期为100ms的AP为例进行说明。AP在每隔100ms的信标帧发送时刻(TBTT，Target Beacon Transmission Time)向无线链路发送一个信标帧，相应的，无线终端在TBTT时刻唤醒无线链路接收信标帧。则无线链路的平均电流功耗根据不同的链路状态下，无线链路的电流大小和每种状态持续的时长相关，参见公式一。For example, an AP whose transmission period of the beacon frame is 100 ms is used as an example for description. The AP sends a beacon frame to the wireless link at the beacon frame transmission time (TBTT, Target Beacon Transmission Time) every 100ms. Correspondingly, the wireless terminal wakes up the wireless link at the TBTT time to receive the beacon frame. Then the average current power consumption of the wireless link is related to the current size of the wireless link and the duration of each state according to different link states, see formula 1.

公式一：Formula one:

Current_avg＝(Current_bottom*(100-T_beacon)+Current_rx*T_beacon)/100Current_avg=(Current_bottom*(100-T_beacon)+Current_rx*T_beacon)/100

其中，Current_avg为无线链路在一个信标帧的接收周期中的平均电流功耗；Current_bottom为无线链路在睡眠状态下的电流功耗，Current_rx为无线链路在唤醒状态下的电流功耗，T_beacon为一个信标帧的接收周期中无线链路的唤醒时长。由于无线链路的接收电流通常比睡眠状态下的电流高十几倍甚至上百倍。所以，在同一信标帧接收周期中，T_beacon越大，Current_avg就越高。Among them, Current_avg is the average current consumption of the wireless link in the receiving period of a beacon frame; Current_bottom is the current consumption of the wireless link in the sleep state, Current_rx is the current consumption of the wireless link in the wake-up state, T_beacon is the wake-up duration of the wireless link in the reception period of one beacon frame. Because the receiving current of the wireless link is usually ten times or even hundreds of times higher than the current in the sleep state. Therefore, in the same beacon frame receiving period, the larger the T_beacon, the higher the Current_avg.

Wi-Fi芯片的片上***(SOC，System on chip)包括CPU、媒体访问控制子层协议层/物理协议层(MAC/PHY，MAC，Media Access Control；PHY，Physical Layer)芯片和无线链路等。在进行数据的接收和发送的过程中，需要通过这几个芯片与无线链路之间的配合来完成。通常信标帧的接收过程通过以下步骤实现，包括：无线终端通过硬件电路在在TBTT之前的固定时刻为无线链路上电，唤醒无线链路。无线链路被唤醒后等待一段时间达到稳定状态，在稳定状态下接收信标帧。对信标帧中的PHY头进行检测和解调，得到信标帧的长度和MAC头的起点，基于该信标帧的长度和MAC头的起点对信标帧进行解调。The system-on-chip (SOC, System on chip) of the Wi-Fi chip includes CPU, media access control sublayer protocol layer/physical protocol layer (MAC/PHY, MAC, Media Access Control; PHY, Physical Layer) chip and wireless link, etc. . In the process of receiving and sending data, it needs to be completed through the cooperation between these chips and the wireless link. Usually, the process of receiving the beacon frame is implemented by the following steps, including: the wireless terminal powers on the wireless link at a fixed time before the TBTT through the hardware circuit, and wakes up the wireless link. After the wireless link is woken up, it waits for a period of time to reach a stable state, and receives beacon frames in the stable state. The PHY header in the beacon frame is detected and demodulated to obtain the length of the beacon frame and the starting point of the MAC header, and the beacon frame is demodulated based on the length of the beacon frame and the starting point of the MAC header.

相关技术中，为了降低接收信标帧的能耗，对通过软件唤醒无线链路的方法进行了改进，将定时唤醒无线链路和解析信标帧的过程设置在了硬件数字电路(HW，Hardware)中。参见图3，通过MAC/PHY数字电路定时唤醒自身以及无线链路，接收到信标帧后，对信标这中的PHY头和MAC头进行解析，确定信标帧中的是否包含用于指示下发数据的唤醒指示标识。如果唤醒指示标识指示没有需要下发的下行数据，不唤醒无线链路，重新关闭HW和无线链路，回到睡眠状态，这个过程中不需要CPU参与。因此，相对于软件方案，节省了 CPU定时唤醒无线链路和解析信标帧带来的额外的CPU电流功耗。In the related art, in order to reduce the energy consumption of receiving the beacon frame, the method of waking up the wireless link through software has been improved, and the process of waking up the wireless link regularly and parsing the beacon frame is set in the hardware digital circuit (HW, Hardware). )middle. Referring to Figure 3, the MAC/PHY digital circuit wakes up itself and the wireless link regularly, and after receiving the beacon frame, parses the PHY header and the MAC header in the beacon to determine whether the beacon frame contains information for indicating The wake-up indicator of the delivered data. If the wake-up indicator indicates that there is no downlink data to be sent, the wireless link will not be woken up, the HW and the wireless link will be closed again, and the sleep state will be returned. No CPU participation is required in this process. Therefore, compared with the software solution, the extra CPU current consumption caused by the CPU periodically waking up the wireless link and parsing the beacon frame is saved.

上述相关技术中，通过硬件唤醒无线链路和解析信标帧，该过程中HW在TBTT之前被定时唤醒。其中，2.4GHz频段的无线信标帧(Wi-Fi Beacon)的传输速率通常采用802.11b标准中的1Mbps，调制方式为二进制相移键控(BPSK，Binary Phase Shift Keying)调制。其中，PHY头和MAC有效数据包(MAC payload)都采用相同的调制方式。参见图4，图4为采用802.11b标准中的1Mbps的传输速率的信标帧的帧结构。其中，该帧结构包括物理层会聚协议前导码(PLCP preamble，Physical Layer Convergence Protocol preamble)、物理层会聚协议头(PLCP header)和子层业务数据单元(PSDU，Physical Service Data Unit)。其中，PLCP preamble包括同步结构(Synchronization)和帧起始定界符(SFD，StartofFrameDelimiter)；PLCP header包括信号(signal)、服务(service)、长度(length)和校验码(CRC，Cyclic Redundancy Check)；PSDU包括MAC头(Media Access Control header)、固定部分(fixed part)、唤醒指示标识(DTIM，Delivery Traffic indication)和其他信息(other IE)。In the above-mentioned related art, the wireless link is woken up by hardware and the beacon frame is parsed, and the HW is periodically woken up before the TBTT in this process. Among them, the transmission rate of the wireless beacon frame (Wi-Fi Beacon) in the 2.4GHz frequency band usually adopts 1Mbps in the 802.11b standard, and the modulation method is Binary Phase Shift Keying (BPSK, Binary Phase Shift Keying) modulation. Among them, both the PHY header and the MAC payload (MAC payload) use the same modulation method. Referring to FIG. 4, FIG. 4 is a frame structure of a beacon frame using a transmission rate of 1 Mbps in the 802.11b standard. The frame structure includes a physical layer convergence protocol preamble (PLCP preamble, Physical Layer Convergence Protocol preamble), a physical layer convergence protocol header (PLCP header) and a sublayer service data unit (PSDU, Physical Service Data Unit). Among them, PLCP preamble includes synchronization structure (Synchronization) and frame start delimiter (SFD, StartofFrameDelimiter); PLCP header includes signal (signal), service (service), length (length) and check code (CRC, Cyclic Redundancy Check) ); the PSDU includes a MAC header (Media Access Control header), a fixed part (fixed part), a wake-up indication (DTIM, Delivery Traffic indication) and other information (other IE).

在解析的过程中，以PHY头作为起始位置，根据事先规定的标准同步信息对接收到的信标帧进行解析，确定出信标帧中PLCP preamble的位置，从而确定出PHY头的起始位置。根据PHY头的起始位置和信标帧中不同帧序列的长度确定唤醒指示标识的位置，根据唤醒指示标识的位置的数据确定是否唤醒无线链路。In the parsing process, the PHY header is used as the starting position, and the received beacon frame is parsed according to the pre-specified standard synchronization information, and the position of the PLCP preamble in the beacon frame is determined, thereby determining the beginning of the PHY header. Location. The position of the wake-up indicator is determined according to the starting position of the PHY header and the lengths of different frame sequences in the beacon frame, and whether to wake up the wireless link is determined according to the data of the position of the wake-up indicator.

上述相关技术中，需要接收完整的信标帧，再对完整的信标帧进行解析，接收和解析信标帧的过程中需要耗费较多的功耗。In the above-mentioned related art, it is necessary to receive a complete beacon frame and then parse the complete beacon frame, and the process of receiving and parsing the beacon frame requires a lot of power consumption.

The predetermined synchronization information is a sequence with fixed content. For example, the predetermined synchronization information includes a media access control sublayer protocol layer (MAC, Media Access Control) field or any of the physical protocol layer headers (PHY header, PHY, Physical Layer).

In some embodiments, the predetermined synchronization information is a sequence carrying fixed information of the access node and a sequence of other information. For example, the predetermined synchronization information is SSID+supported rate (supported rate). In this implementation manner, by increasing the length of the predetermined synchronization information, the accuracy of detecting the predetermined synchronization information is improved. The wake-up indication identifier is used to indicate the situation of downlink data to be delivered in the network node. For example, the wake-up indication is identified as a TIM IE (Traffic Indication Map Element) field or a DTIM (Delivery Traffic Indication) or the like. It should be noted that different types of wake-up indications are located in the same position in the frame structure of the beacon frame.

在本步骤中，无线终端基于同步信息的位置对监听信标帧的周期中的目标时刻进行配置。相应的，无线终端的无线链路包括配置模块、定时模块、同步模块、接收模块和判决模块。继续参见图5。无线终端通过硬件电路中的配置模块对定时模块、同步模块和判决模块进行配置。无线终端通过配置模块对定时模块进行配置，使得定时模块能够在目标时刻唤醒无线链路，通过无线链路接收信标帧。In this step, the wireless terminal configures the target time in the period of monitoring the beacon frame based on the location of the synchronization information. Correspondingly, the wireless link of the wireless terminal includes a configuration module, a timing module, a synchronization module, a receiving module and a decision module. Continue to see Figure 5. The wireless terminal configures the timing module, the synchronization module and the decision module through the configuration module in the hardware circuit. The wireless terminal configures the timing module through the configuration module, so that the timing module can wake up the wireless link at the target time and receive the beacon frame through the wireless link.

在本步骤中，无线终端基于监听信息中每个序列与预定同步信息的匹配度确定该同步信息的位置。该过程通过以下步骤(A1)-(A3)实现，包括：In this step, the wireless terminal determines the position of the synchronization information based on the degree of matching of each sequence in the monitoring information with the predetermined synchronization information. This process is achieved through the following steps (A1)-(A3), including:

(A1)无线终端确定该预设同步信息与监听信息中的序列之间的匹配度。(A1) The wireless terminal determines the matching degree between the preset synchronization information and the sequence in the monitoring information.

其中，该预定同步信息与监听信息中的序列之间的匹配度通过预定同步信息与每个序列之间的相似度确定。无线终端将接收到的监听信息与预定同步信息进行相关运算，得到预定同步信息与监听信息中每个序列之间的匹配度。其中，该监听信息中的每个序列为基于信标帧的结构确定的序列。Wherein, the matching degree between the predetermined synchronization information and the sequence in the monitoring information is determined by the similarity between the predetermined synchronization information and each sequence. The wireless terminal performs a correlation operation between the received monitoring information and the predetermined synchronization information, and obtains the matching degree between the predetermined synchronization information and each sequence in the monitoring information. Wherein, each sequence in the monitoring information is a sequence determined based on the structure of the beacon frame.

(A2)无线终端将匹配度最高的序列确定为该同步信息。(A2) The wireless terminal determines the sequence with the highest matching degree as the synchronization information.

无线终端从多个序列中，确定与该预定同步信息匹配度最高的序列。例如，无线终端对该多个序列对应的匹配度进行排序，得到排序结果，从排序结果中确定与该预定同步信息匹配度最高的序列。The wireless terminal determines the sequence with the highest degree of matching with the predetermined synchronization information from the multiple sequences. For example, the wireless terminal sorts the matching degrees corresponding to the multiple sequences, obtains a sorting result, and determines the sequence with the highest matching degree with the predetermined synchronization information from the sorting result.

(A3)确定该同步信息的位置。(A3) The location of the synchronization information is determined.

无线终端将该匹配度最高的序列确定为该同步信息，将该匹配度最高的序列所在的位置确定为该同步信息的位置。The wireless terminal determines the sequence with the highest matching degree as the synchronization information, and determines the position of the sequence with the highest matching degree as the position of the synchronization information.

在本实现方式中，通过确定监听信息中各个序列与同步信息的匹配度，确定同步信息的位置，进而确定监听信息中同步信息的位置，完成同步，保证了无线终端能够通过监听到的监听信息确定出唤醒指示标识的位置。In this implementation manner, by determining the matching degree of each sequence in the monitoring information and the synchronization information, the position of the synchronization information is determined, and then the position of the synchronization information in the monitoring information is determined to complete the synchronization, and it is ensured that the wireless terminal can pass the monitored monitoring information. The location of the wake-up indicator is determined.

其中，无线终端基于无线终端与接入节点之间的数据交互确定当前无线节点对应的同步信息，基于该同步信息对该无线链路的定时模块进行配置，使得无线链路能够基于该同步信息接收信标帧中的唤醒指示标识。其中，无线终端从该同步信息的位置处，开始接收所述信标帧。该接收信标帧的过程通过以下步骤(1)-(4)实现，包括：The wireless terminal determines the synchronization information corresponding to the current wireless node based on the data interaction between the wireless terminal and the access node, and configures the timing module of the wireless link based on the synchronization information, so that the wireless link can receive the synchronization information based on the synchronization information. Wakeup indicator in beacon frames. Wherein, the wireless terminal starts to receive the beacon frame from the position of the synchronization information. The process of receiving the beacon frame is implemented through the following steps (1)-(4), including:

(1)无线终端确定该信标帧中该同步信息之前的数据量。(1) The wireless terminal determines the amount of data before the synchronization information in the beacon frame.

无线终端基于信标帧的帧结构确定信标帧中，同步信息之前的数据量。其中，该数据量为信标帧中同步信息之前的序列的字节数。无线终端在与接入节点建立连接后，接收接入节点发送的信标帧，对该信标帧进行解析，根据解析得到的解析结果确定同步信息之前的数据量。The wireless terminal determines the amount of data before the synchronization information in the beacon frame based on the frame structure of the beacon frame. The amount of data is the number of bytes in the sequence before the synchronization information in the beacon frame. After establishing the connection with the access node, the wireless terminal receives the beacon frame sent by the access node, parses the beacon frame, and determines the amount of data before the synchronization information according to the parsing result obtained by the parsing.

(2)无线终端基于该数据量和该无线链路的传输速率，确定接收该数据量所需的传输时长。(2) The wireless terminal determines the transmission time required to receive the data amount based on the data amount and the transmission rate of the wireless link.

在本步骤中，无线终端将该数据量和传输速率的商确定为接收该数据量所需的传输时长。In this step, the wireless terminal determines the quotient of the data volume and the transmission rate as the transmission duration required to receive the data volume.

(3)无线终端将该监听周期的起始时刻延后该传输时长，得到目标时刻。(3) The wireless terminal delays the start time of the listening period by the transmission duration to obtain the target time.

其中，该目标时刻为监听该信标帧的新的起始时刻。无线终端基于原始的监听策略，确定监听信标帧的监听周期，将每个监听周期的起始时刻延后该传输时长，得到监听该信标帧的每个监听周期的目标时刻。Wherein, the target time is a new start time for monitoring the beacon frame. The wireless terminal determines the monitoring period for monitoring the beacon frame based on the original monitoring strategy, delays the start time of each monitoring period by the transmission duration, and obtains the target time for monitoring the beacon frame for each monitoring period.

在本步骤中，无线终端将不同的信标帧监听周期中的起始时刻均延后该传输时长，从而延后了无线终端唤醒无线链路的时间。In this step, the wireless terminal delays the start time of different beacon frame monitoring periods by the transmission duration, thereby delaying the time for the wireless terminal to wake up the wireless link.

(4)无线终端从该目标时刻开始，接收该信标帧。(4) The wireless terminal receives the beacon frame from the target time.

需要说明的一点是，不同的接入节点对应的同步信息不同，同步信息与唤醒指示标识之间的距离也不同。在本步骤之前，无线终端通过配置模块对接入节点的同步信息进行配置。相应的，无线终端在第一次接入该接入节点时，存储该接入节点的信标帧对应的同步信息。在之后与接入节点建立连接后，根据连接的接入节点获取该接入节点对应的预定同步信息，通过配置模型基于该预定同步信息对定时模块进行配置，使得定时模块能够在每个监听周期的目标时刻接收监听信息。It should be noted that the synchronization information corresponding to different access nodes is different, and the distance between the synchronization information and the wake-up indication identifier is also different. Before this step, the wireless terminal configures the synchronization information of the access node through the configuration module. Correspondingly, when the wireless terminal accesses the access node for the first time, the synchronization information corresponding to the beacon frame of the access node is stored. After establishing a connection with the access node, obtain the predetermined synchronization information corresponding to the access node according to the connected access node, and configure the timing module based on the predetermined synchronization information through the configuration model, so that the timing module can be used in each monitoring period. The target time to receive monitoring information.

无线终端在每次连接接入节点后，都对监听该接入节点的目标时刻进行配置，则无线终端每次连接到接入节点，通过步骤(1)-(3)确定监听该接入节点的目标时刻。在另一些实施例中，无线终端对定时模块的配置过程，在无线电路与接入节点第一次建立连接时进行，在配置完成后，无线终端存储该目标时刻与接入节点的对应关系，在下一次连接该接入节点时，根据接入节点的节点标识，确定该节点标识对应的目标时刻。相应的，无线终端在与接入节点建立连接时，配置该接入节点对应的信标帧监听周期的起始时刻。无线终端将接入节点与目标时刻的对应关系存储在本地。在每次连接接入点后，确定该接入点是否为第一次接入，如果为第一次接入执行本步骤(1)-(3)；如果不是第一次接入，则根据接入点与目标时刻的对应关系，确定该接入点对应的监听周期的起始时刻。After the wireless terminal connects to the access node each time, it configures the target time to monitor the access node, then each time the wireless terminal connects to the access node, it determines to monitor the access node through steps (1)-(3). target moment. In some other embodiments, the configuration process of the timing module by the wireless terminal is performed when the wireless circuit and the access node are connected for the first time, and after the configuration is completed, the wireless terminal stores the corresponding relationship between the target time and the access node, When connecting to the access node next time, the target time corresponding to the node identifier is determined according to the node identifier of the access node. Correspondingly, when establishing a connection with an access node, the wireless terminal configures the start time of the beacon frame listening period corresponding to the access node. The wireless terminal stores the correspondence between the access node and the target time locally. After each access point is connected, determine whether the access point is the first access, if it is the first access, perform the steps (1)-(3); if it is not the first access, according to The corresponding relationship between the access point and the target time determines the start time of the listening period corresponding to the access point.

需要说明的另一点是，该无线链路为2.4GHz频段的无线链路。其中，该无线链路为单Wi-Fi场景下的无线链路，或者，该无线链路为双Wi-Fi场景下的无线链路。在本申请实施例中，对此不作具体限定。其中，双Wi-Fi场景指无线链路同时通过两个无线链路连接两个接入节点的场景。该两个接入节点为同一路由器中的接入节点，或者，两个接入节点为不同路由器中的接入节点。在本申请实施例中，对此不作具体限定。另外，该双Wi-Fi场景下，无线终端的两个无线链路的频段相同或者不同，例如，两个无线链路均为2.4GHz频段的无线链路；或者，两个无线链路中，一个无线链路为2.4GHZ频段的无线链路，另一个无线链路为5GHz、6GHz等频段的无线链路。Another point that needs to be explained is that the wireless link is a wireless link in the 2.4GHz frequency band. The wireless link is a wireless link in a single Wi-Fi scenario, or the wireless link is a wireless link in a dual Wi-Fi scenario. In the embodiments of the present application, this is not specifically limited. The dual Wi-Fi scenario refers to a scenario in which a wireless link connects two access nodes through two wireless links at the same time. The two access nodes are access nodes in the same router, or the two access nodes are access nodes in different routers. In the embodiments of the present application, this is not specifically limited. In addition, in the dual Wi-Fi scenario, the frequency bands of the two wireless links of the wireless terminal are the same or different, for example, the two wireless links are both wireless links in the 2.4GHz frequency band; or, in the two wireless links, One wireless link is a wireless link in the 2.4GHz frequency band, and the other wireless link is a wireless link in the 5GHz, 6GHz and other frequency bands.

步骤602：无线终端根据该同步信息的位置和位置偏移信息，确定该唤醒指示标识的位置。Step 602: The wireless terminal determines the location of the wake-up indicator according to the location and location offset information of the synchronization information.

其中，该位置偏移信息用于指示该同步信息与该唤醒指示标识之间的位置偏移。Wherein, the position offset information is used to indicate the position offset between the synchronization information and the wake-up indication identifier.

唤醒指示指标与监听信息中的同步信息之间的偏移量固定。在本步骤中，无线终端基于同步信息的位置和位置偏移信息，在监听到的监听信息中确定唤醒指示标识。The offset between the wakeup indicator and the synchronization information in the monitoring information is fixed. In this step, the wireless terminal determines the wake-up indication identifier in the monitored monitoring information based on the position and position offset information of the synchronization information.

其中，该位置偏移信息用于表示该同步信息与该唤醒指示标识之间的位置偏移量。Wherein, the position offset information is used to represent the position offset between the synchronization information and the wake-up indication identifier.

无线终端在监听到的监听信息中，以该同步信息为起点，在该监听信息中，向后偏移该位置偏移信息对应的位置偏移量，得到该唤醒指示标识的位置。In the monitoring information monitored by the wireless terminal, the synchronization information is used as a starting point, and the position offset corresponding to the position offset information is offset backward in the monitoring information to obtain the position of the wake-up indicator.

在本步骤之前，无线终端在与接入节点建立连接时，对接入节点发送的信标帧进行解析，确定接入节点的节点标识，以及该信标帧中唤醒指示标识的位置。无线终端根据该唤醒指示标识的位置与同步信息的位置，确定二者之间的位置偏移量，将该位置偏移量记录为该接入节点的位置偏移信息。在本步骤中，无线终端基于当前连接的接入节点的节点标识，从节点标识和位置偏移信息中确定该节点标识对应的位置偏移信息。参见图5，配置模块根据该接入节点对应的位置偏移信息对该判决模块进行配置。在本步骤中，无线终端通过该判决模块，基于该接入节点对应的位置偏移信息确定该唤醒指示标识的位置。Before this step, when establishing a connection with the access node, the wireless terminal parses the beacon frame sent by the access node to determine the node identifier of the access node and the location of the wake-up indication identifier in the beacon frame. The wireless terminal determines the position offset between the position of the wake-up indication and the position of the synchronization information, and records the position offset as the position offset information of the access node. In this step, the wireless terminal determines the location offset information corresponding to the node identifier from the node identifier and the location offset information based on the node identifier of the currently connected access node. Referring to FIG. 5 , the configuration module configures the decision module according to the position offset information corresponding to the access node. In this step, the wireless terminal determines the location of the wake-up indication identifier based on the location offset information corresponding to the access node through the decision module.

该位置偏移信息为同步信息的长度以及同步信息与唤醒指示指标之间的其他信息的长度之和。例如，信标帧中同步信息长度为Tag length：16；同步信息之后的其他信息长度分别为：Tag length：8和Tag length：1，则确定该值偏移信息为25。The position offset information is the sum of the length of the synchronization information and the lengths of other information between the synchronization information and the wake-up indicator. For example, the length of the synchronization information in the beacon frame is Tag length: 16; the lengths of other information after the synchronization information are: Tag length: 8 and Tag length: 1 respectively, then determine the value of the offset information to be 25.

步骤603：无线终端基于该唤醒指示标识的位置，监听该唤醒指示标识。Step 603: The wireless terminal monitors the wake-up indicator based on the location of the wake-up indicator.

无线终端在进入睡眠状态后，在每个监听周期定时唤醒，接听接入节点下发的信标帧。After the wireless terminal enters the sleep state, it wakes up regularly in each listening period and listens to the beacon frame sent by the access node.

在本步骤中，无线终端将每个监听周期的起始时刻确定为目标时刻。即无线终端控制无线链路在每个监听周期的目标时刻唤醒，从该监听周期的目标时刻开始接收信标帧中的监听信息，基于监听到的监听信息中的唤醒指示标识确定是否唤醒该无线链路。该过程通过以下步骤实现，包括：In this step, the wireless terminal determines the start time of each listening period as the target time. That is, the wireless terminal controls the wireless link to wake up at the target time of each monitoring period, starts to receive the monitoring information in the beacon frame from the target time of the monitoring period, and determines whether to wake up the wireless terminal based on the wake-up indication in the monitored monitoring information. link. The process is accomplished through the following steps, including:

(1)无线终端通过该无线链路进行监听，得到监听信息。(1) The wireless terminal performs monitoring through the wireless link to obtain monitoring information.

其中，该监听信息为信标帧中的部分序列。在本步骤中，无线链路在每个监听周期对应的目标时刻唤醒该无线链路，接收信标帧中的部分序列，得到监听信息。The monitoring information is a partial sequence in the beacon frame. In this step, the wireless link wakes up the wireless link at the target time corresponding to each monitoring period, receives part of the sequence in the beacon frame, and obtains monitoring information.

需要说明的一点是，该监听信息为信标帧中的部分信息。在一些实施例中，响应于监听到该唤醒指示标识，无线终端停止监听。参见图7，在本实现方式中，无线终端在目标时刻之前处于睡眠状态，不接收信标帧中目标时刻之前对应的信息，无线链路在目标时刻被唤醒，接收信标帧中的部分监听信息，在接收到信标帧中的唤醒指示标识后，停止监听本监听周期对应的信标帧，继续进行睡眠状态，直到下一个监听周期。It should be noted that the monitoring information is part of the information in the beacon frame. In some embodiments, in response to monitoring the wake-up indication, the wireless terminal stops monitoring. Referring to Figure 7, in this implementation, the wireless terminal is in a sleep state before the target time, does not receive information corresponding to the target time in the beacon frame, the wireless link is woken up at the target time, and receives part of the monitoring in the beacon frame information, after receiving the wake-up indication in the beacon frame, stop monitoring the beacon frame corresponding to the current monitoring period, and continue to sleep until the next monitoring period.

在本实现方式中，无线终端在监听信标帧时，对于目标时刻之前的监听信息不进行监听，在监听到唤醒指示标识后，停止监听，这样不仅在目标时刻之前不用唤醒无线链路，在监听到唤醒指示标识后，就进入睡眠状态，进一步节省了监听信标帧的时长，进而减小了监听信标帧的功耗。In this implementation, the wireless terminal does not monitor the monitoring information before the target time when monitoring the beacon frame, and stops monitoring after monitoring the wake-up indication, so that not only does it not need to wake up the wireless link before the target time, but also After monitoring the wake-up indication, it enters a sleep state, which further saves the time for monitoring the beacon frame, thereby reducing the power consumption for monitoring the beacon frame.

在一些实施例中，响应于监听到该唤醒指示标识，无线终端继续监听，直到监听完当前监听周期。参见图8，在本实现方式中，无线终端在目标时刻之前处于睡眠状态，不接收信标帧中目标时刻之前对应的信息，无线链路在目标时刻被唤醒，接收信标帧中的部分监听信息，直到该监听周期结束。在本实现方式中，基于无线终端在监听信标帧时，对于目标时刻之前的监听信息不进行监听，这样不仅在目标时刻之前不用唤醒无线链路，节省了监听信标帧的时长，进而减小了监听信标帧的功耗。In some embodiments, in response to monitoring the wake-up indication, the wireless terminal continues to monitor until the current monitoring period is completed. Referring to Figure 8, in this implementation, the wireless terminal is in a sleep state before the target time, does not receive information corresponding to the target time in the beacon frame, the wireless link is woken up at the target time, and receives part of the monitoring in the beacon frame information until the listening period ends. In this implementation, when the wireless terminal monitors the beacon frame, it does not monitor the monitoring information before the target time, so not only does it not need to wake up the wireless link before the target time, but also saves the time for monitoring the beacon frame, thereby reducing The power consumption of monitoring beacon frames is reduced.

(2)无线终端从该监听信息中确定该唤醒指示标识的位置。(2) The wireless terminal determines the location of the wake-up indicator from the monitoring information.

(3)无线终端基于该位置，从该监听信息中解析该唤醒指示标识。(3) Based on the location, the wireless terminal parses the wake-up indication from the monitoring information.

在本步骤中，无线终端在该监听信息的该位置进行解析，得到用于指示唤醒指示标识。In this step, the wireless terminal parses the position of the monitoring information to obtain an indication identifier for indicating wake-up.

在本实现方式中，无线终端通过设置同步信息，使得能够基于同步信息的位置，重新确定信标帧的监听起始时刻，基于新的信标帧起始时刻监听信标帧，从而监听完整的信标帧，减少了监听信标帧的时长，进而降低了无线链路监听信标帧的功耗。In this implementation manner, by setting the synchronization information, the wireless terminal can re-determine the monitoring start time of the beacon frame based on the position of the synchronization information, and monitor the beacon frame based on the new start time of the beacon frame, thereby monitoring the complete The beacon frame reduces the duration of monitoring the beacon frame, thereby reducing the power consumption of the wireless link for monitoring the beacon frame.

需要说明的一点是，在解析唤醒指示标识后，如果唤醒指示标识用于指示需要唤醒无线链路，则无线终端唤醒无线链路，向无线链路连接的接入节点发送唤醒指示信息，表明无线链路已被唤醒。如果唤醒指示标识用于指示无需唤醒无线链路，则无线链路进入睡眠状态后，在下一监听周期继续监听信标帧。It should be noted that, after parsing the wake-up indicator, if the wake-up indicator is used to indicate that the wireless link needs to be woken up, the wireless terminal wakes up the wireless link and sends the wake-up indicator information to the access node connected to the wireless link, indicating that the wireless link needs to be woken up. The link has woken up.
