Description

Awakening method, receiving end equipment and sending end equipment

Technical Field

The present invention relates to the field of wireless local area networks, and in particular, to a wake-up method, a receiving end device, and a sending end device.

Background

With the development of mobile communication technology, mobile applications are becoming more and more diversified, and the functions of devices are becoming more and more abundant. Reducing the energy consumption of devices becomes one of the important technical goals of wireless networks, wherein, intelligent power saving of nodes is a main means for realizing low energy consumption. How to wake up a node after power saving sleep is a difficult problem to be solved, for example, when an emergency service demand or a real-time service demand occurs. In the field of Wireless Local Area Networks (WLANs), solutions related to conventional 802.11 protocols (e.g., 802.11b, 802.11a, 802.11g, 802.11n, 802.11ac, etc.) mainly focus on optimizing the sleep policy of devices.

In a WLAN, a considerable part of the energy of the device is wasted in idle listening (idle listening) when there is no received signal, so in addition to optimizing the sleep strategy, reducing the energy consumption of the device in idle listening is another technical approach to reduce the energy consumption. One current solution is to use a Low Power Wake-Up Receiver (LP-WUR) implementation, where the LP-WUR may be referred to as a Wake-Up Receiver (WUR) for short. The core idea of the scheme is that a receiving end device, such as a Station (STA), adds a new WUR in addition to a traditional main radio (main radio) device, such as an 802.11main radio device and a Wireless Fidelity (Wi-Fi) main radio device.

In this scheme, a sending end device, such as an Access Point (AP), requests a sleeping STA to perform a specific action, which is generally completed through several steps. The AP sends a wake-up packet on the WUR channel. After receiving the wake-up packet, the STA sends a Power Save-Poll (PS-Poll) frame to notify the AP that it is awake through the main radio. The AP sends a specific frame over the main radio channel indicating the behavior that the STA is to perform, e.g., instructing the STA to report data to the AP. And the STA reports data through a main radio channel after receiving the specific frame.

In the process, the sending end device wakes up the receiving end device to require the execution behavior, the signaling frames are more interactive, the flow is complex, and the receiving end device has low response speed to the instruction and is not beneficial to the energy conservation of the receiving end device.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The wake-up method of the embodiment of the invention can be applied to WLAN and other various communication systems, such as: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS) System, a Long Term Evolution (LTE) System, a LTE Frequency Division Duplex (FDD) System, a LTE Time Division Duplex (TDD) System, a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Communication (WiMAX) Communication System, and future Communication systems.

Taking WLAN as an example, the sending end device of the embodiment of the present invention may be an AP, and correspondingly the receiving end device is an STA; or, the sending end device may be an STA, and the receiving end device is an AP correspondingly, which is not limited in the embodiments of the present invention.

Fig. 1 is a schematic diagram of a typical application scenario of a WLAN. As shown in fig. 1, the WLAN includes a transmitting device (e.g., an AP shown in fig. 1) and a receiving device (e.g., a STA shown in fig. 1). The AP is responsible for bi-directional communication with multiple STAs, e.g., the AP shown in fig. 1 transmits downlink data to the STAs (e.g., STA1 and STA2 in fig. 1) or the AP receives uplink data from the STAs (e.g., STA3 in fig. 1). It should be understood that the number of APs and STAs shown in fig. 1 is merely illustrative and that any number of APs and STAs may be included in a WLAN.

Fig. 2 is a schematic diagram of interaction between a sending end device and a receiving end device in a conventional low power consumption scheme. The receiving end device includes a main radio (main radio) 2 and a WUR, and the sending end device includes a main radio (main radio) 1. When the main radio 2 of the receiving end device enters the dormancy, the WUR with low power consumption wakes up to start working. If the sending end device needs to communicate with the receiving end device, the sending end device firstly sends a wake-up packet (packet) to the WUR of the receiving end device through the WUR channel. After the WUR correctly receives the wake-up packet sent to itself, it wakes up the main radio 2 of the receiving end device. The sending end device communicates with the awakening main radio device 2 through the main radio device 1. After the main radio device 2 completes communication with the sending end device, the WUR listens whether there is a wake-up packet sent to the WUR, so that the main radio device 2 is waken up when the wake-up packet is received.

The technology adopts the WUR with low power consumption to replace the main radio device 2 to monitor the channel when the receiving end equipment is idle, so that the energy waste of the receiving end equipment in idle triggering can be effectively reduced. WURs generally have low complexity in terms of circuit configuration, frame (e.g., wake-up packet) structure design, and the like in order to achieve low power consumption. The energy consumption of the WUR monitoring state is about 0.1-1% of that of the main radio device 2, namely less than 100 uW.

It should be understood that a main radio of a certain sink device can only be woken up by the WUR corresponding to the sink device. The main radio transceiver can also be called a main transceiver module or a main radio frequency module, a main radio frequency. Unless otherwise specified herein, the main radio and the WUR both refer to the main radio and the WUR of the same sink device. The sending end device may or may not include a WUR, and when the sending end device does not include a WUR, the main radio thereof may also be considered as a conventional transceiver.

It should be understood that the purpose of waking up the main radio is to put the main radio in an ON (i.e., awake state). Thus, a "wake-up main radio" encompasses the following situations: the main radio device is originally in an OFF (OFF) state, namely a dormant state, and the 'awakening main radio device' refers to a state of converting the main radio device into an ON state; the main radio device is originally in an ON state, and the "waking up of the main radio device" means maintaining the main radio device in the ON state.

As the functions of wireless devices are becoming diversified, the Internet of Things (IoT) has become a development trend of future wireless networks. Therefore, the functions of the devices themselves will play an important role in IoT, and it is necessary to perform appropriate actions at appropriate times. However, if the device is in a power saving state, and the network centric control node (e.g., the sending end device) requires the device to perform the corresponding function or behavior. The specific action that the sending end device requires the sleeping receiving end device to perform is generally completed in 4 steps, as shown in fig. 3. Fig. 3 illustrates an example in which the sending end device is an AP and the receiving end device is an STA. Step 1, the AP sends a wake-up packet on the WUR channel. Step 2, after receiving the wake-up packet, the STA sends a Power Save-Poll (PS-Poll) frame to notify the AP that the AP is awake through the main radio. And 3, the AP sends a specific frame through the main radio channel to indicate the behavior to be executed by the STA, for example, the STA is indicated to report data to the AP. And 4, after receiving the specific frame, the STA reports data through a main radio channel and sends a data (data) frame. In the process, the sending end device wakes up the receiving end device to require the execution behavior, the signaling frames are more interactive, the flow is complex, and the receiving end device has low response speed to the instruction and is not beneficial to the energy conservation of the receiving end device.

In order to solve the above problem, an embodiment of the present invention provides a wake-up method. Fig. 4 shows a schematic flow chart of a wake-up method 100 of an embodiment of the invention. The method 100 includes:

s110, the sending end device generates a wake-up packet, where the wake-up packet includes first information for indicating a behavior that the receiving end device needs to execute.

S120, the sending end device sends the wake-up packet to the receiving end device. Correspondingly, the receiving end device receives the wake-up packet sent by the sending end device.

S130, the receiving end device executes the behavior according to the first information.

According to the awakening method provided by the embodiment of the invention, the first information indicating the behavior required to be executed by the receiving terminal device is added in the awakening packet sent by the sending terminal device to the receiving terminal device, so that the receiving terminal device can directly execute the behavior after receiving the awakening packet, thereby avoiding excessive signaling interaction between the sending terminal device and the receiving terminal device in the awakening process, simplifying the flow, improving the response speed of the receiving terminal device, and reducing the power consumption of the receiving terminal device.

From the perspective of the receiving end device, the wake-up method includes: receiving a wake-up packet by receiving end equipment, wherein the wake-up packet comprises first information used for indicating behaviors which the receiving end equipment needs to execute; and the receiving terminal equipment executes the behavior according to the first information. From the perspective of the sending end device, the wake-up method includes: the method comprises the steps that a sending end device generates a wake-up packet, wherein the wake-up packet comprises first information used for indicating behaviors which need to be executed by a receiving end device; and the sending end equipment sends the awakening packet.

It should be understood that behaviors mentioned in the embodiments of the present invention include, but are not limited to, behaviors involved by applications in the IoT domain.

It should also be understood that the wake-up packet in the embodiment of the present invention may also be referred to as a wake-up frame.

In general, an existing wake-up packet may carry the following information or carry a portion of the following information:

to be compatible with the 802.11legacy mode (802.11legacy mode), the wake up preamble in the wake-up packet may carry the 802.11legacy 802.11 preamble;

a wake-up preamble, whose functions may include wake-up packet detection (wake-up packet detection), channel estimation, etc.;

receiving an address to distinguish the WUR of the awakened receiving end device;

information for identifying the sender, such as a sending address, etc.;

other information, such as some control information, management information, etc.;

check information such as Frame Check Sequence (FCS) and the like.

A specific frame structure of a wake-up packet may be as shown in fig. 5. The wake-up packet includes a legacy 802.11preamble of the legacy 802.11 pilot and a payload of a wake-up packet of the wake-up packet. The payload of wake-up packet includes a wake-up pilot preamble, a Medium Access Control header (MAC header), a frame body (frame body) portion, and an FCS. The payload of wake-up packet may also be referred to as a data part.

In the embodiment of the invention, first information indicating behaviors required to be executed by receiving end equipment is carried in wake up packet. Specifically, the first information may be carried by including a field in the wake up packet, where the field indicates an action that needs to be performed by the receiving device. The field indicating the action to be performed by the receiving device may be a field newly added to the existing wake up packet, or another field multiplexing other functions in the existing wake up packet.

One possible implementation manner is that the wake-up packet includes a first field indicating an action that the receiving device needs to perform, where the first field may be located in a payload of wake-up packet portion or a data portion (data part) of the wake-up packet. Optionally, the first field may be located in the MAC header portion, or may be located in the frame body portion.

Another possible implementation manner is that the wake up packet includes a second field indicating whether the first information is included. When the second field indicates that the first information is contained (for example, the second field is 1), further, the first field indicating the behavior that the receiving end device needs to perform is also included in the wake up packet; when the second field indicates that the first information is not contained (e.g., the second field is 0), the first field is not included in the wake up packet.

Yet another possible implementation is that the wake up packet includes a third field indicating whether control information (or management information) is included. When the third field indicates that the control information (or management information) is contained, for example, the third field is 1, further, the wake up packet contains a fourth field, and the fourth field is used to indicate that the control information (or management information) is different from other management information, for example, the control information different from the management working channel, and is about an action that the receiving end device needs to perform. Further, a first field is included in the wake up packet to indicate a specific behavior.

Specifically, in an embodiment, the sending end device of S120 sends the wake-up packet, which may include: and the sending end equipment sends the awakening packet to the awakening receiver WUR of the receiving end equipment. Correspondingly, the sink device may include a wake-up receiver WUR and a main radio, and the sink device receives a wake-up packet, including: and the receiving end equipment receives the awakening packet through the WUR, wherein the awakening packet is used for awakening the main radio device.

In the embodiment of the present invention, a logic control module (control logic) may respond to and process the wake-up packet sent by the sending end device in the receiving end device. An example of the structure of the sink device may be as shown in fig. 6, and the sink device includes a main radio (main radio) unit, a WUR, a logic control module, an execution module 1, and an execution module 2. The logic control module can perform the function of waking up the main radio on the one hand and can control the execution module 1 and/or the execution module 2 to perform specific actions on the other hand. In particular, the main radio of embodiments of the present invention may be used to communicate with other devices, typically having a receiving function and/or a sending function, for receiving data and/or sending data. The main radio may include at least one of a receiver (receiver) and a transmitter (transmitter).

In an embodiment of the present invention, the wake-up packet may further include second information indicating whether to wake up the receiving function and/or the sending function of the main radio of the sink device. The receiving end device can perform an operation on the main radio according to the second information, for example, wake up a necessary function of the main radio according to the second information.

Specifically, the transmitting device may include second information indicating an awake mode in the awake packet. The wake-up mode refers to which function (receiving function and/or sending function) of the main radio is woken up. The receiving function may correspond to a receiver (receiver); the transmission function may correspond to a transmitter (transmitter). That is, waking up the main radio may refer to waking up at least one of a transmitter or a receiver in the main radio. The awake mode may include at least one of the following modes: neither the transmitter nor the receiver of the main radio needs to wake up; a transmitter to wake up the main radio; waking up a receiver of the main radio; waking up the transmitter and receiver of the main radio. For example, 2bit may be used to indicate the wake-up mode, 00 represents that neither the transmitter nor the receiver of the main radio needs to wake up, 01 represents that the transmitter of the main radio is woken up, 10 represents that the receiver of the main radio is woken up, and 11 represents that the transmitter and receiver of the main radio is woken up. The indication may be carried in an appropriate field of the wake-up packet, which is not limited in this embodiment of the present invention.

The embodiment of the invention can flexibly control whether the receiving function and/or the sending function of the main radio device wakes up or not, and awakens the receiving function and/or the sending function according to the requirement, and does not wake up the receiving function and/or the sending function when the behavior indicated by the first information does not need to transmit or receive data, thereby better saving energy.

For example, for an embodiment in which the receiving end device does not need to reply with any information and is not prepared to receive a downlink frame (downlink frame) from the sending end device, the sending end device may include the second information 00 in the wake-up packet. For the embodiment that the receiving end device needs to send information, the sending end device may include the second information 01 in the wake-up packet. When the transmitting device includes the second information 10 in the wake-up packet, the receiver of the receiving device wakes up to prepare to receive a downlink frame (downlink frame) from the transmitting device. When the sending end device includes the second information 11 in the wake-up packet, both the transmitter and the receiver of the receiving end device wake up, and the receiving end device can reply the information and prepare to receive the downlink frame from the sending end device.

In this embodiment, the sender device does not specify the state of the sender if it is considered that the sender wakes up or sleeps may be decided by the receiver device itself or implicitly based on whether the receiver device needs to send information. At this time, the second information indication included in the wake-up packet of the sending end device may only need 1 bit. The 1bit is used to indicate that the receiver does not need to wake up or to indicate that the receiver is awake.

It should be noted that the receiving end device wakes up the necessary modules according to the indication of the second information of the sending end device, and other modules may select an OFF (sleep) state to save energy. Of course, the receiving end device may also determine whether other modules are to wake up or sleep according to its own needs, which is not limited in the embodiment of the present invention.

In another embodiment of the present invention, the wake-up packet itself can be used to wake up the main radio transceiver of the sink device without additional second information for indication.

In one specific example, a main radio can be used to report data. Here, the reporting data may be reporting data to the sending end device. Execution module 1 and execution module 2 may each be used to perform different types of actions. For example, execution module 1 is used to perform action 1 and execution module 2 is used to perform action 2. In the embodiment of the invention, the sending end equipment adds a first field corresponding to first information in the Wake-up packet to indicate a behavior required to be executed by the receiving end equipment, and the receiving end equipment executes the corresponding behavior according to the first information carried in the first field.

It should be noted that, the specific implementation of the receiving end device may have various ways, and is not limited to the above structure. The receiving end device may also implement connection or control of different modules in other manners, which is not limited in the embodiment of the present invention.

Optionally, as an embodiment, the behavior is to report first data; s130 the receiving end device executes the behavior according to the first information, including: and the receiving terminal equipment reports the first data according to the first information. Specifically, the first information may be used to indicate that the behavior that the receiving end device needs to execute is to report first data to the sending end device; s130 the receiving end device performs the action according to the first information, which may include: and the receiving end equipment reports the first data to the sending end equipment according to the first information. Correspondingly, the sending terminal equipment receives the reported first data.

Specifically, in an example, the first data is data recorded by the receiving end device, that is, the action that the receiving end device needs to perform may be instructing the receiving end device to report the recorded data to the sending end device. For example, the first data may be at least one of temperature information, humidity information, and brightness information collected by the receiving end device. The specific steps of the wake-up method may be as shown in fig. 7:

step 1, a sending end device sends a wake-up packet on a WUR channel, wherein the wake-up packet comprises first information used for indicating a behavior (behavior) required to be executed by a receiving end device, and the first information is carried by a first field. The behavior in fig. 7 is to report the recorded data to the sending end device.

Step 2, the receiving end device wakes up the main radio device (here, the sending function of the main radio device) after receiving the wake-up packet including the first information, sends a Data frame on the main radio channel, and reports the recorded first Data.

For example, the action may be a specific action such as closing a curtain, turning on a television power supply, and turning on a water heater power supply. The specific steps of the wake-up method may be as shown in fig. 10:

The behavior in fig. 10 is to perform a first action (action), for example, an action to close the window covering.

And 2, after receiving the wake-up packet including the first information, the receiving end device wakes up the main radio and executes the action of closing the curtain (executes the first action).

Step 3, after the receiving end device finishes executing the action, or when the action cannot be completed after the specified threshold time is exceeded, sending action feedback information on the main radio channel, for example, specifically, the action feedback information may be included, and feeding back the result of executing the action, for example, the curtain has been closed or the curtain has failed to be closed, to the sending end device. Specifically, when the Action is successfully executed, the Action feedback information may be Action success (ACK of Action) information; the Action feedback information may be an Action failure (NACK of Action) information when the Action cannot be completed beyond a predetermined threshold time.

In the embodiment of the present invention, after receiving the wake-up packet including the first information, the receiving end device may choose to leave only the main radio, the execution module 2 performing the action, and the necessary processing module awake, and other unrelated modules (e.g., the execution module 1) may remain dormant.

Optionally, as shown in fig. 11, in the embodiment of the present invention, the method may further include: and the receiving end equipment sends a wakeup confirmation frame to the sending end equipment. Correspondingly, the sending end device receives the wakeup confirm frame sent by the receiving end device. The scheme is suitable for the condition that the time required by the receiving end equipment to execute the action is long.

The motion feedback information may be carried in a wakeup confirm frame. The action feedback information may be sent by the receiving end device to the sending end device.

Specifically, the action indicating that the sink device needs to perform may be indicating that the sink device performs a specified action (e.g., a first action). For example, the action may be a specific action such as closing a curtain, turning on a television power supply, and turning on a water heater power supply. The specific steps of the wake-up method may be as shown in fig. 12:

step 1, a sending end device sends a wake-up packet on a WUR channel, wherein the wake-up packet comprises first information used for indicating a behavior (behavior) required to be executed by a receiving end device, and the first information is carried by a first field. The behavior in fig. 12 is to perform a first action (action), for example, an action to close the window covering.

Step 2, after receiving the wake-up packet including the first information, the receiving end device wakes up the main radio (at least wakes up the sending function) and executes the action of closing the curtain (executes the first action); and then the receiving end equipment sends action feedback information on a main radio channel, wherein the action feedback information is carried in the awakening confirmation frame. Alternatively, the wakeup confirm frame may be a PS-Poll frame. Specifically, the receiving end device sends a PS-Poll frame including motion feedback information on the main radio channel.

It should be understood that the above case where the receiving-end device feeds back the motion feedback information after performing the motion is described. The wake-up packet sent by the sending end device to the receiving end device may further include a fifth field for indicating whether the receiving end device needs to feed back the action feedback information. For example, the fifth field is used to indicate that no feedback is needed or needed, or to indicate feedback when execution is successful or when execution fails.

It should also be understood that the embodiments of the present invention are merely exemplary in nature and are not intended to limit the specific forms of various packets and frames, such as wake-up packets, data frames, PS-Poll frames, etc.

Optionally, as an embodiment, the first information is a first behavior identifier with a length of N bits. Therefore, the wake-up packet can be simplified by indicating the identification of the N bit instead of directly sending the content of the action required to be executed by the receiving end equipment. This requires that the sending end device and the receiving end device store therein third information indicating a one-to-one correspondence relationship between a plurality of behavior identifiers having a length of M bits and contents of a plurality of behaviors, and a first set formed by the plurality of behaviors is a full set of behaviors that can be executed by the receiving end device served by the sending end device. Optionally, N ═ M, where the plurality of behavior identifiers with the length of M bits include the first behavior identifier.

It should be understood that the third information may be specified in a protocol, or may be determined by negotiation between the sending end device and the receiving end device, which is not limited in this embodiment of the present invention.

Specifically, the sending end device and the receiving end device may pre-define a mapping table, where the mapping table is used to indicate a one-to-one correspondence relationship between an M-bit behavior identifier and contents of multiple behaviors. The full set of behaviors that can be performed by the receiving end device served by the sending end device constitutes a behavior set. The M bit behavior mark can define 2 at most^NThere are different behaviors. For example, 256 behaviors can be defined with 8 bits in table 1.

TABLE 1 mapping table

M bit behavior identification	Content of behaviors
		00000000	Wake up main radio ware
00000001	Reporting temperature information
		……	……
11111101	Turning on the power supply of the water heater
		11111110	Closing curtain
11111111	Reserved field (Reserved bit)

The length of the first information carried in the wake-up packet sent by the sending end device to the receiving end device is N bits. The sender device sets the first information to a corresponding value (e.g., to 00000001) if the receiver device wants to perform a certain action. After receiving the wake-up packet, the receiving end device may obtain the behavior to be executed according to the corresponding relationship (00000001 corresponds to the reported temperature information) in the mapping table, and execute the corresponding operation. The sending terminal equipment in the embodiment of the invention indicates specific behavior content by sending the behavior identifier, has less information amount, accords with the simple design principle of WUP, and can improve the efficiency of signaling transmission.

Optionally, as another embodiment, the first information is a first behavior identifier with a length of N bits. The sending end device and the receiving end device store third information for indicating a one-to-one correspondence relationship between behavior identifiers with lengths of M bits and contents of a plurality of behaviors, and a first set formed by the behaviors is a full set of behaviors that can be executed by the receiving end device served by the sending end device. Before the receiving end device receives the wake-up packet sent by the sending end device, the method may further include: the receiving end device sends fourth information to the sending end device, where N is less than M, a second set formed by behaviors respectively corresponding to at least one behavior identifier with a length of N bits is a full set of behaviors that the receiving end device can execute, and the at least one behavior identifier with a length of N bits includes the first behavior identifier. Correspondingly, before the sending end device generates the wake-up packet, the sending end device may further receive fourth information, which is sent by the receiving end device and used for indicating a one-to-one correspondence relationship between at least one behavior identifier with a length of N bits and at least one behavior identifier with a length of M bits. The sending end device generates the wake-up packet, which may include: and the sending end equipment generates the awakening packet according to the third information and the fourth information.

Specifically, the sending end device and the receiving end device store mapping tables shown in table 1. The mapping table includes a complete set of different behaviors that may be supported by all receiving end devices in the network. In fact, for a receiving end device, its specific behavior may be a subset of the full set. For example, one sensor in the kitchen may be functional to report temperature and humidity information without requiring or supporting the act of closing a window covering.

The following provides a procedure of configuring and negotiating the behavior mapping between the sending end device and the receiving end device. The sending end device and the receiving end device both store mapping tables shown in table 1. The length of the first information carried in the wake-up packet sent by the sending end device to the receiving end device is N bit, wherein N is smaller than M. Thereby, the number of bits occupied by the first information can be further reduced. The negotiation flow between the sending end device and the receiving end device is as follows.

Step 1, the receiving end device generates an N-M mapping table according to its executable behavior and the content in table 1, that is, fourth information indicating a one-to-one correspondence relationship between at least one behavior identifier with a length of N bits and at least one behavior identifier with a length of M bits. Wherein, the action identification of each N bit represents an action which can be executed by the user. And meanwhile, the logic control module of the self is configured to store the N-M mapping table so as to execute the action when receiving the instruction from the sending terminal equipment. For example, when N is 2, the receiving end device may configure the behavior identifier of 2bit as: 00 represents the behavior of waking up the main radio, 01 represents turning on the power supply of the water heater, 10 represents closing the curtain, and 11 represents a reserved field. The N-M mapping table generated by the receiving end equipment is as follows: 00 corresponds to 00000000, 01 corresponds to 11111101, 10 corresponds to 11111110, and 11 corresponds to 11111111.

Step 2, in the network access association stage of the receiving end device or a certain stage after the network access of the receiving end device, the receiving end device sends the N-M mapping table (i.e. 00 corresponds to 00000000, 01 corresponds to 11111101, 10 corresponds to 11111111110, and 11 corresponds to 11111111111) to the sending end device so as to inform the sending end device of the behavior that the receiving end device can execute.

And 3, after receiving the N-M mapping table sent by the receiving end equipment, the sending end equipment inquires the M bit behavior identifier in the table 1, so that the behavior represented by the N bit behavior identifier can be obtained (00 represents a behavior wake main radio module, 01 represents opening of a water heater module, 10 represents closing of a curtain, and 11 represents a reserved field), the N-M mapping table is stored, and a self logic control module is configured, so that an instruction is sent to the receiving end equipment to indicate the receiving end equipment to execute the corresponding behavior when needed. It should be understood that each receiving end device corresponds to its own N-M mapping table. When a sending end device can communicate with multiple receiving end devices, the sending end device needs to store an N-M mapping table corresponding to each receiving end device.

And 4, after receiving the N-M mapping table, the sending end device can send a mapping confirmation frame to the sending end device to inform the sending end device that the N-M mapping table is successfully received. It should be understood that step 4 is an optional step.
