Description

Awakening method and device

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a wake-up method and a wake-up device.

Background

In a Wireless Fidelity (WiFi) network, a considerable part of energy of a device is wasted in listening (idle listening) when no signal is received, and in order to reduce the energy waste in listening of the device, the prior art uses a Low Power Wake Up Radio (LP-WUR) technology to reduce the energy waste in listening of the device.

The core idea of LP-WUR is that the sink device (e.g., station STA) includes a wake-up radio WUR portion in addition to a Primary Connectivity Radio (PCR). As shown in fig. 1, when the PCR is in the off state, the WUR wakes up to start working, when other devices (such as the Access Point AP in fig. 1) need to communicate with the device with the WUR and the PCR (such as the Station STA in fig. 1), the Access Point (AP) sends a wake-up frame to the WUR of the Station (Station, STA), after the WUR correctly receives the wake-up frame, the PCR is woken up to perform normal transceiving of the wireless frame, and the WUR itself can go to the sleep or the off state.

after the WUR of the STA receives the wakeup frame sent by the AP, there are two possible wakeup modes: in the first mode, the WUR of the STA wakes up the PCR after receiving the wake-up frame, and the PCR sends a response frame to the AP after successful contention through channel contention so as to inform the AP that the PCR enters the wake-up state; and in the second mode, the AP sends a wakeup frame to the WUR of the STA, and sends a trigger frame or a data frame to the PCR of the STA after waiting for a certain time delay, and the PCR sends a response frame to the AP after receiving the trigger frame or the data frame sent by the AP so as to inform the AP that the PCR enters the wakeup state.

In the prior art, the AP may configure the STA to notify the AP that the main transceiver module enters the wakeup state by using the wakeup mode one or the wakeup mode two, but the wakeup method in the prior art cannot effectively manage multiple wakeup modes, and has the problems of low network resource utilization rate and large energy consumption.

Detailed Description

The embodiment of the application provides a wake-up method, which is applied to a wireless local area network, wherein the system structure of the wireless local area network comprises at least one Access Point (AP) and at least one Station (STA). As shown in fig. 1, the STA in the embodiments of the present application includes a wake-up radio WUR module and a host transceiver module. Illustratively, the STA may be a tablet, a desktop, a laptop, a notebook, an Ultra-mobile Personal Computer (UMPC), a handheld Computer, a netbook, a Personal Digital Assistant (PDA), a mobile phone, or other user equipment that can be networked, and in this embodiment, the specific form of the STA is not particularly limited.

For example, as shown in fig. 1, when the STA has no information to transmit or receive, the host transceiver module (e.g., PCR) of the STA is in a shutdown state, and the WUR module of the STA wakes up to start operating. If the AP needs to communicate with the STA, the AP firstly sends a wakeup frame to a WUR module of the STA, the WUR module wakes up a PCR (polymerase chain reaction) of a main transceiver module of the STA after correctly receiving the wakeup frame, then the WUR module is switched into a sleep state or a closing state, at the moment, the PCR of the main transceiver module in the wakeup state can adopt a first wakeup mode or a second wakeup mode to inform the AP that the PCR of the main transceiver module enters the wakeup state, and the AP can communicate with the PCR of the main transceiver module in the wakeup state. After the main transceiver module PCR and the AP are communicated, the main transceiver module PCR can enter a closed state again, and meanwhile the WUR module wakes up to continuously monitor whether a wake-up frame exists or not so as to wake up the main transceiver module PCR again, and the energy waste during idle monitoring of the equipment can be effectively reduced. However, the wake-up method in the prior art cannot fully utilize network resources, and has the problem of high energy consumption. In order to solve the problem, embodiments of the present application provide a wake-up method, which can effectively manage wake-up modes of multiple WURs, maximize network resource utilization, and avoid unnecessary energy waste.

for example, the wake-up method provided in the embodiment of the present application may be applied to the STA100 shown in fig. 2. As shown in fig. 2, the STA100 includes: processor 101, memory 102, interface 103, bus 104, and the like.

The processor 101: is a core component of the STA100 and may be used to run an operating system of the STA100 and applications (including system applications and third party applications) on the STA 100.

In this embodiment, the processor 101 may be specifically a Central Processing Unit (CPU), a general purpose processor, a Digital Signal Processor (DSP), an application-specific integrated circuit (ASIC), a Field Programmable Gate Array (FPGA) or other programmable logic device, a transistor logic device, a hardware component, or any combination thereof, which may implement or execute various exemplary logic blocks, modules, and circuits described in connection with the disclosure of the embodiment of the present application; a processor may also be a combination of computing functions, e.g., comprising one or more microprocessors, a DSP and a microprocessor, or the like.

the memory 102: may be used to store software programs and modules that are stored in the memory 102 for execution by the processor 101 to perform various functional applications and data processing of the STA 100. Memory 102 may include one or more computer-readable storage media. The memory 102 includes a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required for at least one function, and the like, for example, a program implementing the wake-up method provided by the embodiment of the present application.

In this embodiment, the memory 102 may specifically include a volatile memory (volatile memory), such as a random-access memory (RAM); the memory may also include a non-volatile memory (non-volatile memory), a flash memory (flash memory), a hard disk (HDD) or a solid-state drive (SSD); the memory may also comprise a combination of memories of the kind described above.

The transceiver 103: the wireless monitoring system can comprise a main transceiver module and a WUR module, wherein the main transceiver module is used for communicating with other equipment, and if no information is transmitted or received within a period of time, the main transceiver module is switched from a wakeup state to a closed state so as to reduce energy waste when the main transceiver module is in idle monitoring; when the main transceiver module is in a closed state, the WUR module wakes up to start working, the WUR module wakes up the main transceiver module after receiving a wake-up frame sent by other equipment (such as an AP), and the WUR module is switched into a sleep state or a closed state after the main transceiver module enters the wake-up state. It can be understood that the off state of the main transceiver module in the embodiment of the present application is different from the sleep state of the main transceiver module in the prior art, and the main transceiver module is not completely turned off when in the sleep state, but only a majority of the main transceiver module is turned off, and when in the off state, the main transceiver module is completely turned off.

Bus 104: the bus of the computer can be divided into a data bus, an address bus and a control bus according to the types of information transmitted by the computer, and the data bus, the address bus and the control bus are respectively used for transmitting data, data addresses and control signals.

S301, the AP sends a wake-up frame to the STA.

The wakeup frame is used to wake up the PCR of the main transceiver module of the STA, for example, when the STA does not receive and transmit information, the PCR of the main transceiver module of the STA is in a closed state, and the WUR module wakes up to start working. When the AP needs to communicate with the STA, the AP may send a wakeup frame to the STA for waking up the main transceiver module PCR in the off state. For example, as shown in fig. 1, the AP may send a wake frame to the STA's wake-up radio WUR module for waking up the host transceiver module PCR.

s302, the STA receives the wake-up frame sent by the AP.

it is understood that step S302 may be performed by the transceiver 103 shown in fig. 2, and in one example, step S302 may be performed by a WUR module included in the transceiver 103.

s303, the STA awakens the main transceiver module according to the awakening frame, so that the main transceiver module enters an awakening state.

It is understood that step S303 may be performed by the processor 101 shown in fig. 2.

For example, as shown in fig. 1, the processing module of the STA may wake up the main transceiver module PCR of the STA according to the wake-up frame sent by the AP, so that the main transceiver module PCR enters a wake-up state, and then the WUR module transitions to a sleep or off state, and the AP may communicate with the wake-up main transceiver module PCR.

s304, if the STA adopts the second wake-up mode to inform the AP that the main transceiver module enters the wake-up state and the STA does not receive the wireless frame sent by the AP within the first time length, the STA adopts the first wake-up mode to inform the AP that the main transceiver module enters the wake-up state; or the main transceiver module is switched from the wake-up state to the off state.

It is understood that step S304 may be performed by the transceiver 103 shown in fig. 2, and in one example, step S304 may be performed by a primary transceiver module included in the transceiver 103.

The first wake-up mode comprises that after the STA competes for a channel successfully, a first response frame is sent to the AP, and the first response frame is used for informing the AP that the main transceiver module enters a wake-up state; the second awakening mode comprises that the STA sends a second response frame to the AP after receiving a wireless frame sent by the AP, and the second response frame is used for informing the AP that the main transceiver module enters an awakening state; the first time period is greater than 0.

for example, under the condition that the STA adopts the second awake mode, if the STA does not receive the wireless frame sent by the AP within the first duration after receiving the awake frame, there are two processing manners: the first processing mode is that after receiving the first time length of the wakeup frame, the STA informs the AP that the main transceiver module enters the wakeup state by adopting the first wakeup mode; the second processing mode is that after receiving the first time length of the wakeup frame, the main transceiver module switches from the wakeup state to the off state.

For example, the reason why the radio frame sent by the AP is not received by the STA within the first time period after the wake-up frame is received may include: when the link quality of the STA is poor, the STA may not receive the wireless frame sent by the AP; or, when the interference of the STA is strong, the STA may not receive the wireless frame sent by the AP; or, when the traffic volume currently sent by the AP is large, the STA may not receive the wireless frame sent by the AP; alternatively, other situations may also result in the STA not receiving the radio frame transmitted by the AP. The embodiment of the present application does not limit a specific reason why the STA does not receive the wireless frame sent by the AP within the first duration.

For example, if the main transceiver module PCR of the STA does not receive the wireless frame sent by the AP within the first duration after receiving the wakeup frame, in order to ensure that the AP can normally communicate with the STA and avoid unnecessary energy waste, a first processing mode may be adopted, in which the main transceiver module PCR performs channel contention, and after the channel contention succeeds, a first response frame is sent to the AP to notify the AP that the main transceiver module PCR enters the wakeup state. Compared with the prior art that when the AP configures the STA to adopt the second awakening mode, if the STA cannot receive the wireless frame sent by the AP all the time, the STA waits for the wireless frame sent by the AP all the time, the AP can be informed that the main transceiver module PCR of the STA enters the awakening state by adopting the first awakening mode when the wireless frame sent by the AP is not received within the first time length, so that the probability of successful communication between the AP and the STA is improved, and the purpose of energy conservation is achieved. For example, in order to improve the probability of successful communication between the AP and the STA while avoiding unnecessary energy waste, the embodiment of the present application may adopt a first processing manner.

For example, if the main transceiver module PCR of the STA does not receive the wireless frame sent by the AP within the first duration after receiving the wakeup frame, in order to reduce energy waste of the main transceiver module PCR, the second processing mode may also be directly adopted, and the main transceiver module PCR is switched from the wakeup state to the off state, so as to avoid unnecessary energy waste.

for example, the first duration in the embodiment of the present application may be configured in advance, or the STA may receive first timeout duration information sent by the AP, where the first timeout duration information is used to indicate the first duration. The first timeout duration information may be carried in a wakeup frame, a WUR mode setup response frame, a broadcast frame, an association response frame, a re-association response frame, or a probe response frame. It is to be understood that the frame structure of the above frame is as shown in fig. 4, and the first timeout period information may be carried in the WUR operation information element of the above frame.

for example, if the first timeout duration information is carried in the wakeup frame, the AP may send the WUR to the STA; if the first timeout duration information is carried in the mode establishing response frame, the AP can send the PCR to the STA; if the first timeout duration information is carried in the broadcast frame, the first timeout duration information can be sent out in the broadcast frame by the AP in advance; if the first timeout duration information is carried in an association response frame, a re-association response frame or a probe response frame, the association response frame, the re-association response frame and the probe response frame may be sent to a primary transceiver module PCR of the STA by the AP, where the association response frame, the re-association response frame and the probe response frame are sent by the AP after receiving an association request frame, a re-association request frame and a probe request frame sent by the STA, respectively. The embodiment of the present application does not limit in which frame the first timeout duration information is specifically carried.

According to the awakening method provided by the embodiment of the application, the main transceiver module of the STA is awakened by receiving the awakening frame sent by the AP according to the awakening frame, so that the main transceiver module enters an awakening state; if the STA adopts the second wake-up mode to inform the AP that the main transceiver module enters the wake-up state and the STA does not receive the wireless frame sent by the AP within the first time period, the STA adopts the first wake-up mode to inform the AP that the main transceiver module enters the wake-up state or the main transceiver module is switched from the wake-up state to the off state. Compared with the prior art that when the STA fails to receive the wireless frame sent by the AP, the wireless frame sent by the AP is waited for all the time, the awakening method in the application can not only avoid unnecessary energy waste, but also improve the probability of successful communication between the AP and the STA.

The present application further provides an embodiment, referring to fig. 5, in the case that the PCR is in the wake-up state, the wake-up method may further include S305 to S308.

s305, the STA transmits a WUR mode setup request frame to the AP.

it is understood that step S305 may be performed by the transceiver 103 shown in fig. 2, and in one example, step S305 may be performed by a primary transceiver module included in the transceiver 103.

S306, the AP receives the WUR mode setup request frame.

s307, the AP sends a WUR mode setup response frame to the STA.

The WUR mode setup response frame carries indication information, and the indication information is used to indicate the STA to adopt the second awake mode. For example, the AP may send a WUR mode setup response frame to the PCR of the STA for informing the STA that the AP configures the awake mode of the STA to be the second awake mode.

S308, the STA receives the WUR mode establishment response frame sent by the AP.

it is understood that step S308 may be performed by the transceiver 103 shown in fig. 2, and in one example, step S308 may be performed by a primary transceiver module included in the transceiver 103.

referring to fig. 6, if the STA uses the second wake-up mode to notify the AP of the STA to perform the wake-up state and the STA does not receive the wireless frame sent by the AP within the first time period, the STA uses the first wake-up mode to notify the AP that the main transceiver module enters the wake-up state, and then the wake-up method further includes S309.

And S309, if the STA adopts the first wake-up mode and the STA fails to receive the wireless frame sent by the AP in the second time length, the main transceiver module is switched from the wake-up state to the closed state.

It is understood that step S309 may be performed by the transceiver 103 shown in fig. 2, and in one example, step S309 may be performed by a main transceiver module included in the transceiver 103.

for example, the STA adopts the first awake mode, and the STA does not successfully receive the radio frame sent by the AP within the second duration, where there may be a case that:

The first case: the main transceiver module PCR competition channel is not successful within a second time length when the STA enters the first wake-up mode;

The second case: the STA enters a second time length of the first wake-up mode, after the main transceiver module successfully competes for the channel by the PCR, a first response frame is sent to the AP, and the AP does not receive the first response frame sent by the PCR;

The third situation: and in a second time length when the STA enters the first wake-up mode, after the main transceiver module PCR competes for the channel successfully, the STA sends a first response frame to the AP, and after the AP receives the first response frame sent by the main transceiver module PCR successfully, the AP sends a wireless frame to the main transceiver module PCR, but the main transceiver module PCR does not receive the wireless frame.

The above situations may be considered that the STA does not successfully receive the wireless frame sent by the AP within the second duration of entering the first awake mode. The embodiment of the application does not limit the specific situation that the STA does not successfully receive the wireless frame sent by the AP within the second duration of entering the first awake mode.

illustratively, when the STA notifies the AP that the primary transceiver module PCR enters the awake state by using the first awake mode, if the STA does not successfully receive the wireless frame sent by the AP within the second duration, to avoid unnecessary energy waste, the STA instructs the primary transceiver module to switch from the awake state to the off state, thereby further saving energy.

for example, the second duration in the embodiment of the present application may be configured in advance, or the STA may receive second timeout duration information sent by the AP, where the second timeout duration information is used to indicate the second duration. The second timeout duration information may be carried in a wakeup frame, a WUR mode setup response frame, a broadcast frame, an association response frame, a re-association response frame, or a probe response frame. It is to be understood that the frame structure of the above frame is as shown in fig. 7, and the second timeout period information may be carried in the WUR operation information element of the above frame.

Exemplarily, if the second timeout duration information is carried in the wakeup frame, the AP may send the WUR to the STA; if the second timeout duration information is carried in the mode establishment response frame, the AP may send the PCR to the STA; if the second timeout duration information is carried in the broadcast frame, the second timeout duration information can be sent out in the broadcast frame by the AP in advance; if the second timeout duration information is carried in the association response frame, the re-association response frame, or the probe response frame, the association response frame, the re-association response frame, and the probe response frame may be sent to the primary transceiver module PCR of the STA by the AP, where the association response frame, the re-association response frame, and the probe response frame are sent by the AP after receiving the association request frame, the re-association request frame, and the probe request frame sent by the STA, respectively. The embodiment of the present application does not limit in which frame the second timeout duration information is specifically carried.

For example, in this embodiment of the present application, the first timeout duration information and the second timeout duration information may be carried in the same frame, or may be carried in different frames. It can be understood that, when the first timeout duration information and the second timeout duration information are carried in the same frame, the frame structure of the frame is as shown in fig. 8, and the first timeout duration information and the second timeout duration information may be carried in the WUR operation information unit of the frame.

According to the awakening method provided by the embodiment of the application, the main transceiver module of the STA is awakened by receiving the awakening frame sent by the AP according to the awakening frame, so that the main transceiver module enters an awakening state; if the STA adopts the second wake-up mode to inform the AP that the main transceiver module enters the wake-up state, and the STA does not receive the wireless frame sent by the AP within the first time period, the STA adopts the first wake-up mode to inform the AP that the main transceiver module enters the wake-up state, and if the STA does not successfully receive the wireless frame sent by the AP within the second time period, the main transceiver module is switched from the wake-up state to the off state. Compared with the prior art that when the STA fails to receive the wireless frame sent by the AP, the wireless frame waiting for the AP to send all the time is not needed, the awakening method in the application can avoid unnecessary energy waste, improve the probability of successful communication between the AP and the STA, and can turn off the main transceiver module when the STA adopts the first awakening mode and does not successfully receive the wireless frame sent by the AP within the second time length, so that energy is further saved.

In another embodiment of the present application, a wake-up method is provided, referring to fig. 9, and is applied to a station STA, the STA including a wake-up radio WUR module and a master transceiver module, the master transceiver module being in an off state, and the method may include S901-S904.

S901, the AP sends a wake-up frame to the STA.

S902, the STA receives the wake-up frame sent by the AP.

it is understood that step S902 may be performed by the transceiver 103 shown in fig. 2, and in one example, step S902 may be performed by a WUR module included in the transceiver 103.

And S903, the STA awakens the main transceiver module according to the awakening frame, so that the main transceiver module enters an awakening state.

It is understood that step S903 may be performed by the processor 101 shown in fig. 2.

And S904, if the STA adopts the first wake-up mode to inform the AP that the main transceiver module enters the wake-up state and the STA does not successfully receive the wireless frame sent by the AP within the third duration, the main transceiver module is switched from the wake-up state to the closed state.

It is understood that step S904 may be performed by the transceiver 103 shown in fig. 2, and in one example, step S904 may be performed by a primary transceiver module included in the transceiver 103.

For example, when the preconfigured STA notifies the AP that the primary transceiver module PCR enters the awake state using the first awake mode, if the STA does not successfully receive the wireless frame sent by the AP within the third duration, to avoid unnecessary energy waste, the STA instructs the primary transceiver module PCR to switch to the off state. It is understood that the third time period is greater than 0, and the third time period may be the same as or different from the first time period and the second time period.

For example, the third duration in the embodiment of the present application may be configured in advance, or the STA may receive third timeout duration information sent by the AP, where the third timeout duration information is used to indicate the third duration. The third timeout duration information may be carried in a wakeup frame, a WUR mode setup response frame, a broadcast frame, an association response frame, a re-association response frame, or a probe response frame. The third timeout duration information, the first timeout duration information, and the second timeout duration information may be carried in the same frame or may be carried in different frames. The frame structure of the frame carrying the third timeout period information may refer to the frame structure diagrams shown in fig. 4 and 7.

According to the awakening method provided by the embodiment of the application, the main transceiver module of the STA is awakened by receiving the awakening frame sent by the AP according to the awakening frame, so that the main transceiver module enters an awakening state; and if the STA adopts a first wake-up mode to inform the AP that the main transceiver module enters a wake-up state and the STA fails to successfully receive the wireless frame sent by the AP within a third time length, the main transceiver module is switched from the wake-up state to a closed state. Compared with the prior art that when the AP configures the STA to adopt the first wake-up mode, if the STA does not successfully perform frame interaction with the AP all the time, the main transceiver module is always in the wake-up state, the wake-up method in the application can close the PCR of the main transceiver module when the STA adopts the first wake-up mode and the STA does not successfully receive the wireless frame sent by the AP in the third time length, so that unnecessary energy waste is avoided.

the present application further provides an embodiment, referring to fig. 10, in the case that the PCR is in the wake-up state, the method may further include S905-S908.

S905, the STA sends a WUR mode establishment request frame to the AP.

It is understood that step S905 may be performed by the transceiver 103 shown in fig. 2, and in one example, step S905 may be performed by a primary transceiver module included in the transceiver 103.

S906, the AP receives the WUR mode setup request frame.

S907, the AP sends a WUR mode setup response frame to the STA.

the WUR mode setup response frame carries indication information, which is used to indicate the STA to adopt the first awake mode. For example, the AP may send a WUR mode setup response frame to the PCR of the STA for informing the STA that the AP configured awake mode is the first awake mode.

S908, the STA receives the WUR mode setup response frame sent by the AP.

As shown in fig. 11, after the WUR module receives the wakeup frame sent by the AP, the processing module wakes up the main transceiver module according to the wakeup frame, and there are different wakeup methods when the STA uses different wakeup modes.

In the first case: when the pre-configured STA adopts the first wake-up mode, if the STA fails to perform frame interaction with the AP within the third time length after entering the wake-up mode, the main transceiver module is switched from the wake-up state to the off state, and unnecessary energy waste is avoided.

in the second case: when the pre-configured STA adopts a second wake-up mode, if the STA receives the wireless frame sent by the AP within the first time period after receiving the wake-up frame, the STA sends a second response frame to the AP after receiving the wireless frame sent by the AP so as to inform the AP main transceiver module to enter a wake-up state.

In the third case: when the preconfigured STA adopts the second wake-up mode, if the STA does not receive the wireless frame sent by the AP within the first duration after receiving the wake-up frame, two processing manners may be adopted, where the first manner is: after receiving the first duration of the wakeup frame, the STA informs the AP that the main transceiver module enters the wakeup state by adopting a first wakeup mode, so that the probability of successful communication between the AP and the STA is improved, and unnecessary energy waste is avoided; the second way is: after the STA receives the first duration of the wakeup frame, the main transceiver module is switched from the wakeup state to the off state, and unnecessary energy waste is avoided.

In a fourth case: when the pre-configured STA adopts the second wake-up mode, the STA does not receive the wireless frame sent by the AP within the first time length after receiving the wake-up frame, if the STA receives the first time length of the wake-up frame, the STA adopts the first wake-up mode to inform the AP that the main transceiver module enters the wake-up state, and the STA does not successfully receive the wireless frame sent by the AP within the second time length after entering the first wake-up mode, the main transceiver module is switched from the wake-up state to the off state, and energy is further saved.

According to the awakening method provided by the embodiment of the application, the AP is informed to enter the awakening state or the main transceiver module is switched from the awakening state to the closing state by adopting the first awakening mode in the first time length after the awakening frame is received when the wireless frame sent by the AP is not received, the wireless frame sent by the AP does not need to be waited all the time like the prior art, unnecessary energy waste can be avoided, and the probability of successful communication between the AP and the STA can be improved by switching to the first awakening mode. And the STA closes the main transceiver module when the wireless frame sent by the AP is not successfully received within the second time after entering the first wake-up mode, so that energy can be further saved.
