Description

Method and device for transmitting data

Technical Field

The embodiment of the invention relates to the field of communication, in particular to a method and a device for transmitting data in the field of communication.

Background

One wireless communication device may have multiple different radios, and this difference may be used to reduce the wireless communication low device operating power consumption due to the different radios' transmission rates and standby power consumption. A Station (STA) has two sets of radios, a primary radio and a secondary radio (otherwise known as a wake-up radio). The secondary radio has a receiving capability, the primary radio has both transmitting and receiving capabilities, the secondary radio has a lower power consumption, and the primary radio has a higher power consumption. 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 an STA, the AP first sends an awake signal, and when a secondary radio of the STA receives the awake signal, the AP sends an awake message (an output terminal provides voltage or current) to a main control chip, and the main control chip turns on a main radio device. After the primary radio of the STA is turned on, it can receive the 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 with which the STA is associated, the STA may be mistakenly woken up.

Detailed Description

It should be understood that the technical solutions of the embodiments of the present invention can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) System, a LTE Frequency Division Duplex (FDD) System, a LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), or a Worldwide Interoperability for microwave Access (WiMAX) communication System, and future communication systems.

The embodiment of the invention provides a method for transmitting data. The method may be performed by a awakened device (or called a sender) and/or an awakened device (or called a receiver). The awakened device has two sets of radios, a primary radio and a secondary radio (otherwise known as a wake-up radio). Or the awakened device has a set of radios that can operate in both primary and secondary radio modes. The secondary radio has a reception bandwidth less than the reception bandwidth and the transmission bandwidth of the primary radio. Further, the received signal frequency of the secondary radio is less than the received signal frequency and the transmitted signal frequency of the primary radio. In particular, the secondary radio has a receiving capability, which can receive the narrowband signal sent by the wake-up device, although the secondary radio may also have a sending capability; the primary radio has both transmit and receive capabilities and can receive or transmit broadband signals. The awakened device supports a Wake-up receiver (WUR) function, or the awakened device supports a Wake-up radio function. The awakened device supporting 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 awakened device, the wake-up device may first send a wake-up signal; when the secondary radio of the awakened device receives the wake-up signal, the primary radio is turned on. After the main radio device of the awakened device is turned on, the downlink data sent by the awakened device can be received. Since the power consumption of the secondary radio is less when it is active than the power consumption of the primary radio, the awakened device can reduce power consumption by such a way that the secondary radio listens to the wake-up signal and wakes up the primary radio in a dormant state by the wake-up signal.

The wake-up signal may be referred to as a characteristic narrowband signal, and the characteristic narrowband signal may be a narrowband signal having certain characteristic information, which is predetermined by the wake-up device and the wake-up device. For example, the characteristic information may include at least one of the following information of the signal: transmission frequency, transmission waveform, modulation and coding scheme, spread spectrum information, the number of repetitions of transmission, transmission time, Identification (Identification, abbreviated as "ID"), and the like. That is to say, 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 scheme, or the characteristic narrowband signal may be a signal transmitted at a specific time, or the characteristic narrowband signal may be a signal repeatedly transmitted for a specific number of times, and the specific form of the characteristic narrowband signal is not limited in the embodiment of the present invention. When the awakened device receives the characteristic narrowband signal, by identifying information such as frequency, waveform, modulation and coding scheme, etc. of the characteristic narrowband signal, the primary radio device may be awakened to receive the downstream data when one or more of the information is determined to match the characteristic information. When the feature ID is used to distinguish the awakened device or the awakened device group, or the feature tag ID is used to identify whether the feature narrowband signal is a broadcast signal. The awakened device and the awakening device can carry the characteristic indication of the characteristic narrowband signal in the association request, the association reply or the message or the dormancy negotiation message received or sent last before the awakened device enters the dormancy state, and the preset characteristic information is indicated.

The embodiment of the invention can be applied to a Wireless Local Area Network (WLAN for short), and the standard adopted by the WLAN at present is IEEE802.11 series. The WLAN may include a plurality of Basic Service Sets (BSSs).

Fig. 1 shows a schematic view 100 of an application scenario provided in an embodiment of the present invention, which includes an AP110 and an STA120, an Access Point (AP) of an Access Point class and a non-Access Point class (non-AP STA). Each BSS may contain an AP and a plurality of non-AP STAs associated with the AP. In the embodiment of the present invention, the awakening device may be an AP, and the awakened device may be an STA; or the awakening device may be a STA and the awakened device may be an AP; or the awakening device may be an AP, and the awakened device may also be an AP; or the waking device may be a STA and the awakened device may also be a STA.

An AP is also referred to as a wireless access point or hotspot, etc. The AP is an access point for a mobile subscriber to enter a wired network, and is mainly deployed in a home, a building, and a campus, and typically has a coverage radius of several tens of meters to hundreds of meters, and may be deployed outdoors. The AP acts as a bridge connecting the network and the wireless network, and mainly functions to connect the wireless network clients together and then to access the wireless network to the ethernet. Specifically, the AP may be a terminal device or a network device with a wireless fidelity (WiFi) chip. Optionally, the AP may be a device supporting 802.11ax standard, and further optionally, the AP may be a device supporting multiple WLAN standards such as 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, or subsequent versions.

The STA may be a wireless communication chip, a wireless sensor, or a wireless communication terminal. For example, a mobile phone supporting a WiFi communication function, a tablet computer supporting a WiFi communication function, a set top box supporting a WiFi communication function, a smart television supporting a WiFi communication function, a smart wearable device supporting a WiFi communication function, a vehicle-mounted communication device supporting a WiFi communication function, and a computer supporting a WiFi communication function. Optionally, a station may support an 802.11ax system, and further optionally, the station supports multiple WLAN systems such as 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, or subsequent releases.

It should be understood that the awakened device receiving the wake-up signal via the secondary radio may be the awakened device receiving the wake-up signal via the secondary radio sent by the wake-up device associated with the awakened device, the wake-up signal then being a normal wake-up signal; or the awakened device receives a wake-up signal transmitted by an attacker through the secondary radio device, the wake-up signal being an abnormal wake-up signal, and specifically, the awakened device may determine whether the wake-up signal is an abnormal wake-up signal or a normal wake-up signal in S230.

Optionally, the method further comprises: the awakened device awakens the main radio device according to the awakening signal, and the main radio device enters an active state from a sleep state.

As an optional embodiment, after the awakened device awakens the primary radio device according to the wake-up signal, the method 200 further comprises: the awakened device causes the primary radio device to be in the active state for a first preset period of time; if the secondary radio device of the awakened device does not receive the frame sent by the awakening device associated with the awakened device within the first preset time period, the awakening device enables the primary radio device to enter the sleep state from the active state. I.e., when the primary radio does not receive a frame within the first preset time period, 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 consumption.

S220, the awakened device determines whether the receiving of the wake-up signal by the secondary radio device is an abnormal event.

In S220, the awakened device determines whether the receiving of the wake-up signal by the secondary radio device is an abnormal event, which may be determined by the following six ways:

in a first mode, the awakened 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 awakened device determines whether the secondary radio device receives the wake-up signal as an abnormal event based on the number and/or frequency of suspicious events occurring.

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 to wait for receiving the wake-up device to send a frame, and when the primary radio device receives the frame sent by the wake-up device, the wake-up signal received by the secondary radio device can be considered as a normal wake-up signal, and the radio device can be considered as a normal event when receiving the wake-up signal; when the secondary radio device receives the frame sent by the wake-up device but the primary radio device does not receive the frame sent by the wake-up device, the secondary radio device is considered to receive the wake-up signal as an abnormal event, and the awakened 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 sent by the awakened device is received, for example, when the awakened device receives a signal through the secondary radio device, the primary radio device wakes up to receive data, but the primary radio device does not receive the frame sent by the awakened device, the awakened device considers the suspicious event as a suspicious event, records the number of times of occurrence of the suspicious event, and/or the frequency, and when the number of times of occurrence of the suspicious event is greater than a first threshold, the awakened device determines that the secondary radio device receives the awakened signal as an abnormal event; when the number of suspicious events occurring is less than the first threshold, the awakened device determining that the secondary radio device received the wake-up signal as a normal event; and/or, when the frequency of the suspicious event occurrence 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 frequency of the suspicious event occurrence is less than the second threshold, the awakened device determines that the secondary radio device receives the wake-up signal as a normal event. For example, the number of times a suspicious event occurs may be one or more times. Of course, a wake-up signal may wake up the primary radio device to receive a frame once, or a wake-up signal may wake up the primary radio device to receive a frame multiple times, or a wake-up signal may wake up the primary radio device to receive a frame within a specific time period, and specifically, the relationship between the wake-up signal and the frame may be specified by a network configuration or a protocol, which is not limited in the embodiments of the present invention.

As an alternative embodiment, the awakened device may send the number and/or frequency of suspicious events to the awakening device associated with the awakened device, and the awakening device associated with the awakened device determines whether the awakening signal received by the awakened device is an abnormal event according to the number and/or frequency of suspicious events, for example, if the awakened device receives three awakening signals, but does not receive the three awakening signals, wakes up the primary radio device 3 times, but the primary radio device has not received the frame sent by the awakening device, the awakened device will receive the 3 awakening signals as 3 suspicious events through the secondary radio device, and report the 3 suspicious events to the awakening device associated with the awakened device, and if the first threshold is 2, the awakening device associated with the awakened device determines that 3 is greater than 2, the radio may receive three wake-up signals as an exception event.

As an alternative embodiment, when the wake-up signal may include the first feature information and the security token, if the awakened device finds that the first feature information is the first preset feature information, but the security token does not match, the awakened device may determine the wake-up signal as the suspicious wake-up signal; or the awakened device finds that the first characteristic information does not match the first preset characteristic information but the security token matches, the awakened device may determine the wake-up signal as a suspect wake-up signal. The awakened device can send the times and/or frequency of the suspicious wake-up signals to the awakening device associated with the awakened device, the awakening device associated with the awakened device receives the times and/or frequency, comparison is carried out according to the times and/or frequency of the wake-up signals sent to the awakened device by the awakened device associated with the awakened device, when the sent times of the wake-up signals and the times of the suspicious wake-up signals reported by awakening are found to be the same, the awakened device is considered to be a normal event when receiving the wake-up signals through the secondary radio device, otherwise, the suspicious wake-up signals are abnormal events, and the suspicious wake-up signals can be understood as suspicious events.

In a second mode, the awakened device determines that the secondary radio device receives the wake-up signal as an abnormal event according to whether the first characteristic information in the wake-up signal received is the first preset characteristic information. The awakening device and the awakened device associated with the awakened device can negotiate in advance or configure first preset feature information in the awakening signal to identify the awakening signal, and when the first feature information in the awakening signal received by the awakened device through the secondary radio device is the first preset feature information, the awakened device determines that the awakening signal received through the secondary radio device is a normal event; when the first characteristic information in the wake-up signal received by the awakened device through the secondary radio device is not the first preset characteristic information, the awakened device determines that the wake-up signal received through 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 characteristic information may be encapsulated in a packet header of a Data packet, and when the awakened device matches the first characteristic information in the packet header of the Data packet with the first preset characteristic information and finds that the first characteristic information in the packet header of the Data packet is not the first preset characteristic information, the awakened device regards that the Data packet is not a normal Data packet, and may not receive a Physical layer protocol Data Unit (PPDU), that is, may not analyze the PPDU.

In a third mode, the awakened device determines that the receiving of the awakening signal is an abnormal event according to whether second feature information in a frame sent by the awakening device and received by the main radio device is second preset feature information. The awakening device and the awakened device associated with the awakened device can negotiate in advance or configure second preset characteristic information in a frame to identify whether the awakened device and the awakened device are abnormal events or not, and when the second characteristic information in the frame received by the awakened device through the primary radio device is the second preset characteristic information, the awakened device determines that the awakening signal received by the secondary radio device is a normal event; when the second characteristic information in the frame received by the awakened device through the primary radio device is not the second preset characteristic information, the awakened device determines that the awakening signal received through the secondary radio device is an abnormal event. Specifically, the second preset characteristic information may be a dynamic AID and/or a dynamic MAC address.

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

A fourth way for the awakened device to determine whether the secondary radio receiving the wake-up signal is an abnormal event, includes: after the awakened device receives the wake-up signal through the secondary radio device, the awakened device receives a security token sent by the wake-up device; the awakened device determines from the security token whether the secondary radio receiving the wake-up signal is an anomalous event. Specifically, the wake-up device associated with the awakened device may negotiate a security token with the awakened device, for example, the security token may be: a dynamic password token, an asynchronous password token, a challenge response token, and the like, optionally, a specific field in a trigger frame sent by a wake-up device associated with the awakened device may carry the security token, and the specific field may be determined by negotiation or by configuration. The awakened device verifies the identity of the awakening device according to a preset security token in a specific field of the received trigger frame, and if the specific field bears the preset security token, the awakened device determines that the awakening signal received by the secondary radio device is a normal event; if the specific field carries information other than the preset security token, the awakened device determines that receiving the wake-up signal by the secondary radio device is an abnormal event.

Fifth, the awakened device determining whether the secondary radio receiving the wake-up signal is an abnormal event, comprising: after the awakened device causes the primary radio device to enter an active state from a sleep state in accordance with the wake-up signal, the awakened device sending a validation string to an awakening device associated with the awakened device; the awakened device receives verification reply information sent by the awakening device according to the verification character string; the awakened device determines from the verification reply message whether the secondary radio receiving the wake-up signal is an abnormal event. Specifically, after being woken up, the wakened device may send a verification character string to a wakening device associated with the wakening device, the wakening device associated with the wakening device replies verification reply information to the wakened device according to the verification character string and its own private information, and the wakened device verifies the identity of the wakening device according to the verification reply information, that is, it is also possible that an attacker intercepts the verification character string as the wakening device, but the attacker's own private information is different from the private information of the wakening device associated with the wakened device, and the wakened device determines that the secondary radio device receives the wake signal as an abnormal event if the attacker replies the verification reply information is not the verification reply information of the wakening device associated with the wakened device.

It should be understood that the awakened device may send the validation string after the main radio device of the awakened device is awakened, or send the validation string to the awakened device after the main radio device of the awakened device receives the downlink data packet, or the validation string may be carried in an acknowledgement message that the awakened device receives the downlink data packet.

A sixth way, the awakened device receives, via the master radio device, a frame sent by an awakening device associated with the awakened device, where the frame sent by the awakening device associated with the awakened device includes second indication information used by the awakened device to determine whether the radio device receiving the awakening signal is the abnormal event; the awakened device determines whether the secondary radio receiving the wake-up signal is the abnormal event according to the second indication information.

For example, the second indication information may have the following nine different indications:

1. the second indication information is used to indicate a number of times a wake-up device associated with the awakened device sends a wake-up signal to the secondary radio device. A waking device associated with a awakened device may broadcast a first frame to a plurality of awakened devices, which may include a number of times the waking device associated with the plurality of awakened devices transmits a wake-up signal to each awakened device.

2. The second indication information is used to indicate a frequency at which a wake-up device associated with the awakened device transmits a wake-up signal to the secondary radio device. A waking device associated with a awakened device may broadcast a first frame to a plurality of awakened devices, which may include therein a frequency at which the waking device associated with the plurality of awakened devices transmits a wake-up signal to each of the awakened devices.

3. The second indication information indicates that a waking device associated with the awakened device is not transmitting frames to the primary radio device. The waking device associated with the plurality of awakened devices may broadcast a first frame to the plurality of awakened devices, but the first frame may be addressed to a specific awakened device, for example, to the first awakened device, but the first frame includes second indication information indicating that the waking device associated with the plurality of awakened devices does not transmit the first frame to the primary radio device of the second awakened device, that is, the second awakened device does not need to receive the wake-up signal, the primary radio device of the second awakened device does not wake up to receive the first frame, and when the second awakened device receives the wake-up signal through the secondary radio device, it may be considered that the second awakened device receives the wake-up signal through the secondary radio device as an abnormal event.

4. The second indication information is used to indicate a waking device associated with the awakened device to transmit a frame to the primary radio device. The wake-up device associated with the plurality of awakened devices may broadcast a first frame to the plurality of awakened devices, but the first frame may be addressed to a specific awakened device, for example, to the first awakened device, but the first frame includes second indication information indicating that the wake-up device associated with the plurality of awakened devices transmits a first frame to the primary radio device of the first awakened device, that is, the first awakened device needs to receive the wake-up signal, the primary radio device of the first awakened device needs to wake up to receive the first frame, and when the first awakened device receives the wake-up signal through the secondary radio device, it may be considered that the first awakened device receives the wake-up signal through the secondary radio device is a normal event.

5. The second indication information is used for indicating that the awakened device does not need to send a frame to the awakening device associated with the awakened device. The wake-up device associated with the plurality of awakened devices may broadcast a first frame to the plurality of awakened devices, but the first frame may be sent to a specific awakened device, for example, to the first awakened device, but the first frame includes second indication information indicating that the awakened device does not need to send a frame to the wake-up device associated with the awakened device, that is, the second awakened device does not need to send data.

6. The second indication information is used for the awakened device to send a frame to the awakening device. The wake-up device associated with the plurality of awakened devices may broadcast a first frame to the plurality of awakened devices, but the first frame may be sent to a specific awakened device, for example, to the first awakened device, the first frame includes second indication information indicating that the awakened device needs to send a frame to the wake-up device associated with the awakened device, and when the first awakened device receives the wake-up signal through the secondary radio device and receives a first message sent by the wake-up device associated with the plurality of awakened devices, the first message requesting the second awakened device to send data, the first awakened device may be considered to be a normal event when receiving the wake-up signal through the secondary radio device.

7. The second indication information is used to indicate that a wake-up device associated with the awakened device is not transmitting the wake-up signal to the secondary radio device. The waking device associated with the plurality of awakened devices may broadcast a first frame to the plurality of awakened devices, but the first frame may be addressed to a specific awakened device, for example, to the first awakened device, but the first frame includes second indication information indicating that the waking device associated with the awakened device does not transmit the wake signal to the secondary radio device of the second awakened device, that is, the second awakened device does not need to receive the wake signal, and when the second awakened device receives the wake signal through the secondary radio device, it may be considered that the second awakened device receives the wake signal through the secondary radio device as an abnormal event.

8. The second indication information is also used to indicate that the master radio device is not indicated from the sleep state to the active state by a wake-up device associated with a awakened device. A waking device associated with a woken device may broadcast a first frame to a plurality of woken devices, for example, the first frame including second indication information indicating that the primary radio of the first woken device is not indicated by the associated device with the woken device from a sleep state to an active state, and when the secondary radio of the first woken device receives a wake-up signal, the wake-up signal wakes up the primary radio so that the primary radio enters the active state from the sleep state, the secondary radio of the first woken device may be considered to receive the wake-up signal as an abnormal event.

9. The second indication information is further used for indicating the number of times that the wake-up device associated with the awakened device sends the wake-up signal. When the number of times the awakened device receives the wake-up signal is greater than or less than the number of times the wake-up signal is transmitted as indicated by the second indication information, it may be considered that the awakened device receives the wake-up signal through the secondary radio device as an abnormal event.

It should be understood that the second indication information may have at least one of the nine indications, and may be determined as required during the implementation process, the second indication information may be that the wake-up device associated with the awakened device is carried in a frame and sent to the awakened device, or may be that the wake-up device associated with the awakened device is sent to the awakened device separately, which is not limited in this embodiment of the present invention, and in addition, the second indication information may also indicate the awakened device in other manners, for example, the second indication information may indicate that the awakened device and the awakened device associated with the awakened device do not send the wake-up signal to the awakened device for a specific second period of time, when the awakened device receives the wake-up signal via the secondary radio within the second time period, then the receipt of the wake-up signal via the secondary radio is considered an abnormal event.

S230, when the awakened device determines that the secondary radio device receives the wake-up signal as the abnormal event, the awakened device sends a channel switching request message to an awakening device associated with the awakened device, wherein the channel switching request message is used for requesting to switch a channel for receiving the wake-up signal; or, the awakened device sends a change awakening signal request message to the awakening device associated with the awakened device, where the change awakening signal request message is used to request to change the awakening signal.

Optionally, when the awakened device determines that the secondary radio receives the wake-up signal as the abnormal event, and the awakened device has been awakened, the awakened device configures the primary radio device to enter a sleep state.

As an optional embodiment, when the awakened device determines that the secondary radio device receives the wake-up signal as a normal event, the awakened device makes the primary radio device keep active or sleep according to first indication information included in the wake-up signal, where the first indication information is used for indicating that the awakened device keeps the primary radio device active or sleep.

Specifically, when the awakened device determines that receiving the wake-up signal by the secondary radio is an abnormal event, then processing may take three ways:

first, when the primary radio has been awakened, the awakened device may configure the primary radio to enter a sleep state from an active state to reduce power consumption by the primary radio.

In a second way, the awakened device may send a channel switching request message to the awakening device associated with the awakened device, where the channel switching request message is used to request to switch channels, that is, when the awakened device determines that the secondary radio device receives the awakening signal is an abnormal event, the awakening device associated with the awakened device may select an appropriate first channel for the awakened device according to the channel switching request message when receiving the channel switching request message, and then send a switching message to the awakened device, where the switching message includes, for example, a number of the first channel, and the awakened device may switch the channel receiving the awakening channel from the current channel to the first channel according to the number of the first channel in the switching message, and optionally, the switching message may be carried in a High-Throughput Control (High Throughput Control, simply "H-Control") field or an Aggregate Control (simply "a-Control") field.

In a third mode, the awakened device sends a wake-up signal change request message to the awakening device associated with the awakened device, and when the awakening device associated with the awakened device receives the wake-up signal request message, the awakening device may update the wake-up signal, for example, change the waveform characteristic of the wake-up signal, change the number of the wake-up signal, and send the updated information of the wake-up signal to the awakened device. The wake-up device associated with the awakened device may send a dynamic wake-up signal to the awakened device, and the dynamic wake-up signal may be associated with the awakened device, thereby ensuring that the received dynamic wake-up signal is the only wake-up signal.

It should be understood that in the examples of the present invention, mention is made of: a awakened device sends a message to an awakening device associated with the awakened device, either a primary wireless device of the awakened device sends a message to the awakening device associated with the awakened device, or a secondary wireless device of the awakened device sends a message to the awakening device associated with the awakened device; the secondary radio device may send a message to the wake-up device associated with the awakened device as long as the secondary radio device has the capability to send data, and likewise, the secondary radio device may receive the message sent by the wake-up device before the primary radio device is awakened when receiving the message sent by the wake-up device, and the primary radio device may receive the message sent by the wake-up device and the secondary radio device may also receive the message sent by the wake-up device after the primary radio device is awakened, although the embodiments of the invention are not limited thereto.

Therefore, according to the method for transmitting data provided by the embodiment of the present invention, the awakened device may determine whether the secondary radio device receives the wake-up signal as an abnormal event, and when the wake-up signal is an abnormal event, may adopt an appropriate processing manner, for example, to enable the primary radio device to enter a sleep state, so as to reduce the power consumption of the primary radio device; or, the awakened device can request to change the awakening signal or change the signal for receiving the awakening signal, so that the reliability and stability of the received data are further ensured.
