Technical field

The embodiments of the present application relate to the field of communications, and in particular, to a method and apparatus for transmitting data in the field of communications.

Background technique

A wireless communication device can have a variety of different radios, and since the transmission rates and standby power consumption of different radios are different, the difference can be utilized to reduce the wireless communication low device operating power consumption. A station (STA) has two sets of radios, a primary radio and a secondary radio (or called a wake-up radio). The secondary radio has a receiving capability, the primary radio has both transmit and receive capabilities, the secondary radio consumes less power, and the primary radio consumes more power. When there is no data transmission, the STA is generally in a sleep state. When an access point (AP) needs to send downlink data to the STA, the AP first sends a wake-up signal. When the secondary radio of the STA receives the wake-up signal, it can send a wake-up message (the output terminal provides voltage or current) to the master. The control chip, the main radio chip is turned on by the main control chip. After the STA's primary radio is turned on, it can receive downlink data sent by the AP. However, if the STA receives the wake-up message sent by the attacker instead of the wake-up message sent by the AP associated with the STA, the STA may be caused to wake up by mistake.

The embodiment of the present application provides a method for transmitting data. The method can be performed by a wake-up device (or called a sender) and/or a wake-up device (or, a receiver). The awakened device has two sets of radios, a primary radio and a secondary radio (or called a wake-up radio). Or the device being woken up has a set of radios that can operate in both primary and secondary radio modes. The receiving bandwidth of the secondary radio is smaller than the receiving bandwidth and transmission bandwidth of the primary radio. Further, the received signal frequency of the secondary radio device is smaller than the received signal frequency and the transmitted signal frequency of the primary radio device. Specifically, the secondary radio device has a receiving capability, and can receive a narrowband signal transmitted by the wake-up device. Of course, the secondary radio device can also have a transmitting capability; the primary radio device has both transmitting and receiving capabilities, and can receive or transmit a wideband signal. The wake-up device supports the wake-up receiver (WUR) function, or the wake-up device supports the wake-up radio function. A wake-up device that supports the WUR function is in a sleep state when there is no data transmission. When the wake-up device needs to send downlink data to the wake-up device, the wake-up device may first send a wake-up signal; when the wake-up device receives the wake-up signal, the master radio device is turned on. After the master radio of the wake-up device is turned on, it can receive the downlink data sent by the wake-up device. Since the power consumption of the secondary radio device is smaller than the power consumption of the primary radio device when operating, the wake-up device can detect the wake-up signal through the secondary radio device, and reduce the work by awakening the wake-up signal to wake up the main radio device in the sleep state. Consumption.

The wake-up signal may be referred to as a characteristic narrowband signal, and the characteristic narrowband signal may be a narrowband signal having a certain characteristic information pre-approved by the wake-up device and the wake-up device. For example, the feature information may include at least one of the following information of the signal: a transmission frequency, a transmission waveform, a modulation and coding scheme, a spread spectrum information, a number of repetitions of transmission, a transmission time, an identification (ID), and the like. That is, the characteristic narrowband signal may be a signal having a specific frequency or a specific waveform, or the characteristic narrowband signal may be a signal of a specific modulation and coding mode, or the characteristic narrowband signal may be a signal transmitted at a specific time, or the feature The narrowband signal may be a signal that is repeatedly transmitted a certain number of times, and the specific form of the characteristic narrowband signal is not limited in this embodiment of the present application. When the wake-up device receives the characteristic narrowband signal, by identifying the frequency, waveform, modulation and coding mode of the characteristic narrowband signal, etc., when determining that one or more of the information matches the feature information, the master radio device can be woken up To receive downlink data. The feature ID here can be used to distinguish the wake-up device from the wake-up device group, or the signature ID can be used to identify whether the feature narrowband signal is a broadcast signal. The wake-up device and the wake-up device may carry a feature indication of the feature narrowband signal in the message or the dormancy negotiation message finally received or sent before the association request, the association reply, or the wake-up device enters the dormancy, and indicate the pre-agreed feature information.

FIG. 2 shows a method 200 for transmitting data provided by an embodiment of the present application. The method 200 includes:

S210. The awake device receives a wake-up signal through a secondary radio device, where the wake-up signal is used to wake up a primary radio device of the awake device, the awake device including the primary radio device and the secondary radio device.

It should be understood that the wake-up device receives the wake-up signal through the secondary radio device, and the wake-up device may receive the wake-up signal sent by the wake-up device associated with the wake-up device through the secondary radio device, and the wake-up signal is a normal wake-up signal; or The wake-up device receives the wake-up signal sent by the attacker through the secondary radio device, and the wake-up signal is an abnormal wake-up signal. Specifically, the wake-up device can determine whether the wake-up signal is an abnormal wake-up signal or a normal condition in S230. Wake up signal.

Optionally, the method further includes: the wake-up device wakes up the primary radio device according to the wake-up signal, and the master radio device enters an active state from a sleep state.

As an optional embodiment, after the awake device wakes up the primary radio device according to the wake-up signal, the method 200 further includes: the wake-up device causes the primary radio device to be at a first preset time The segment is in the activated state; if the secondary radio device of the awake device does not receive the frame sent by the awake device associated with the awake device within the first preset time period, the awake device makes The master radio enters the sleep state from the activated state. That is, when the primary radio does not receive a frame within the first predetermined time period, in order to reduce the power consumption of the primary radio, the awakened device may cause the primary radio to enter a sleep state to save power.

S220. The wake-up device determines whether the wake-up signal is received by the secondary radio device as an abnormal event.

In S220, the device that wakes up to determine whether the wake-up signal is received by the secondary radio device is an abnormal event, and may be determined by the following six manners:

In a first mode, the wake-up device determines whether the secondary radio device receives the wake-up signal as a suspicious event according to whether the primary radio device receives a frame sent by the wake-up device; the wake-up device occurs according to a suspicious event. The number and/or frequency determines whether the secondary radio receives the wake-up signal as an abnormal event.

Specifically, when the secondary radio device of the wake-up device receives the wake-up signal, the primary radio device wakes up according to the wake-up signal and waits for the receiving wake-up device to send the frame. When the primary radio device receives the frame sent by the wake-up device, the secondary radio may be considered as the secondary radio. The wake-up signal received by the device is a normal wake-up signal. It can be considered that the receiving of the wake-up signal by the radio is a normal event; when the secondary radio receives the frame sent by the wake-up device, but the primary radio does not receive the frame sent by the wake-up device If the secondary radio receives the wake-up signal as an abnormal event, which can be considered as a wake-up signal sent by the attacker, the wake-up device determines that the received wake-up signal is an abnormal event.

More specifically, the awakened device may determine a suspicious event according to whether a frame transmitted by the awake device is received, for example, when the awake device receives a signal through the secondary radio, the primary radio wakes up to receive data, but the primary radio does not receive Wake up the frame sent by the device, consider this thing to be a suspicious event, the wake-up device records the number of occurrences of the suspicious event, and/or frequency. When the number of suspicious events occurs is greater than the first threshold, the wake-up device will Receiving, by the secondary radio device, the wake-up signal as an abnormal event; when the number of occurrences of the suspicious event is less than the first threshold, the wake-up device determines that the secondary radio device receives the wake-up signal as a normal event And/or, when the frequency of the suspicious event occurs is greater than a second threshold, the awakened device determines that the secondary radio device receives the wake-up signal as an abnormal event; when the suspicious event occurs less frequently than the a second threshold, the wake-up device receiving the wake-up letter from the secondary radio Determined to be normal event. For example, a suspicious event can occur one or more times. Of course, a wake-up signal can wake up the main radio to wake up Receiving a frame, or a wake-up signal, can wake up the master radio to wake up to receive multiple frames, or a wake-up signal can wake up the master radio to wake up to receive the frame within a certain period of time, specifically, can be configured through the network or The protocol stipulates the relationship between the wake-up signal and the frame, and the embodiment of the present application is not limited thereto.

As an optional embodiment, the awake device may send the number and/or frequency of occurrence of the suspicious event to the awake device associated with the awake device, and the awake device associated with the awake device may occur according to receiving the suspicious event. The number and/or frequency determines whether the wake-up signal received by the wake-up device is an abnormal event. For example, the wake-up device receives three wake-up signals, but does not receive it, wakes up the master radio 3 times, but the master radio device has been If the frame sent by the wake-up device is not received, the wake-up device will receive 3 wake-up signals through the secondary radio device as 3 suspicious events, and report the 3 suspicious events to the wake-up device associated with the wake-up device, assuming the first The threshold is 2, and if the wakeup device associated with the device being woken up determines that 3 is greater than 2, the radio device may receive the three wakeup signals as an abnormal event.

As an optional embodiment, when the wakeup signal may include the first feature information and the security token, if the wakeup device finds that the first feature information is the first preset feature information, but the security token does not match, the The wake-up signal is determined as a suspicious wake-up signal; or the wake-up device finds that the first feature information does not match the first preset feature information, but the security token matches, and the wake-up device can determine the wake-up signal as a suspicious wake-up signal. The awakened device may transmit the number and/or frequency of the suspect wake-up signal to the wake-up device associated with the wake-up device, the wake-up device associated with the wake-up device receiving the number and/or frequency, according to the wake-up device The wake-up device compares the number and/or frequency of wake-up signals sent by the wake-up device, and when the number of sent wake-up signals is found to be the same as the number of wake-up reported suspicious wake-up signals, the wake-up device is considered to pass the secondary radio. The device receives the wake-up signal as a normal event, otherwise it is an abnormal event, and the suspicious wake-up signal can be understood as a suspicious event.

In a second mode, the awakened device determines, according to whether the first feature information in the wake-up signal is the first preset feature information, that the secondary radio device receives the wake-up signal as an abnormal event. The wake-up device associated with the device being woken up and the device being woken up may negotiate in advance or configure first preset feature information in the wake-up signal to identify the wake-up signal, when the wake-up device receives the first one of the wake-up signals through the secondary radio device When the feature information is the first preset feature information, the wakeup device determines that the wakeup signal is received by the secondary radio device is a normal event; when the wakeup device receives the wakeup signal through the secondary radio device, the first feature information is not the first pre- When the feature information is set, the wake-up device determines that the wake-up signal received by the secondary radio device is an abnormal event. Specifically, the first preset feature information may be a dynamic associated identity (AID) and/or a dynamic media access control (MAC) address. For example, the first feature information may be encapsulated in a packet header of the data packet. When the wakeup device matches the first preset feature information by using the first feature information in the data packet header, the first feature information in the packet header of the data packet is not found. When the first preset feature information is used, the device that wakes up considers that the data packet is not a normal data packet, and may not receive a physical layer protocol data unit (PPDU), that is, the PPDU may not be parsed.

In a third mode, the wake-up device determines whether to receive the wake-up signal as an abnormal event according to whether the second feature information in the frame sent by the wake-up device received by the master radio device is the second preset feature information. The wake-up device associated with the device being woken up and the device being woken up may negotiate in advance or configure second preset feature information in the frame to identify whether it is an abnormal event, when the wake-up device receives the second of the frames received by the master radio device When the feature information is the second preset feature information, the wake-up device determines that receiving the wake-up signal by the secondary radio device is a normal event; when the second feature information in the frame received by the wake-up device through the primary radio device is not the second preset When the feature information is called, it is called The wake-up device determines that the wake-up signal received by the secondary radio is an abnormal event. Specifically, the second preset feature information may be a dynamic AID and/or a dynamic MAC address.

It should be understood that, in the embodiment of the present application, the frame received by the awake device may be the control plane data or the user plane data, which is not limited in this embodiment of the present application.

In a fourth mode, the wake-up device determines whether the secondary radio device receives the wake-up signal as an abnormal event, including: after the wake-up device receives a wake-up signal by using a secondary radio device, the wake-up device receives wake-up a security token sent by the device; the wake-up device determining, according to the security token, whether the secondary radio device receives the wake-up signal as an abnormal event. Specifically, the awake device associated with the awake device may negotiate a security token used by the awake device, for example, the security token may be: a dynamic password token, an asynchronous crypto token, and a challenge response token, etc., optionally The specific field in the trigger frame sent by the wake-up device associated with the wake-up device may carry the security token, and the specific field may be determined by negotiation or determined by configuration. The wake-up device verifies the identity of the wake-up device according to the preset security token in the specific field of the received trigger frame. If the specific field carries the preset security token, it is considered that the wake-up device determines that the wake-up signal is received by the secondary radio device. Normal event; if the specific field carries not the preset security token but other information, the wake-up device determines that receiving the wake-up signal through the secondary radio is an abnormal event.

In a fifth mode, the wake-up device determines whether the secondary radio device receives the wake-up signal as an abnormal event, including: causing the master radio device to enter an active state from a sleep state according to the wake-up signal. After the state, the awake device sends a verification string to the awake device associated with the awake device; the awake device receives verification reply information sent by the awake device according to the verification string; the awake device is based on The verification reply information determines whether the secondary radio device receives the wake-up signal as an abnormal event. Specifically, the wake-up device may send a verification string to the wake-up device associated with the wake-up device after being woken up, and the wake-up device associated with the wake-up device returns the verification reply message to the wake-up device according to the verification string and the information of the private device. The wake-up device verifies the identity of the wake-up device according to the verification reply information, that is, the attacker may intercept the verification string as the wake-up device, but the attacker's own private information is different from the private information of the wake-up device associated with the wake-up device, and the attacker The verification reply message replied by the user is not the verification reply information of the wake-up device associated with the device being woken up, and the wake-up device determines that the secondary radio device receives the wake-up signal is an abnormal event.

It should be understood that the wakeup device may send the verification string after the wakeup device's master radio device is woken up, or send the verification string to the wakeup device after the wakeup device's master radio device receives the downlink data packet. The string, or the verification string, may be carried in the confirmation message that the wakeup device receives the downlink data packet. The timing and manner of sending the verification string to the wake-up device are not limited in this embodiment.

The primary radio device of the first awake device needs to wake up to receive the first frame. When the first awake device receives the wake-up signal through the secondary radio device, the first awake device can be considered to receive the wake-up signal through the secondary radio device. Normal event.

5. The second indication information is used to indicate that the wake-up device does not need to send a frame to a wake-up device associated with the awakened device. The awake device associated with the plurality of awake devices may broadcast the first frame to the plurality of awake devices, but may be sent to the specific awake device in the first frame, for example, to the first awake device, but the first Included in the frame, the second indication information indicates that the awake device does not need to send a frame to the awake device associated with the awake device, that is, the second awake device does not need to send data, and the second The wake-up device receives the wake-up signal through the secondary radio device, and receives the first message sent by the wake-up device associated with the plurality of wake-up devices, where the first message requests the second wake-up device to send data, then the second The wake-up signal received by the wake-up device through the secondary radio is an abnormal event.
