Description

Communication mode switching method, device, storage medium, processor and system

Technical Field

The present invention relates to the field of communications, and in particular, to a method, an apparatus, a storage medium, a processor, and a system for switching a communication mode.

Background

Wireless fidelity (WiFi) is a wireless local area network technology created in the IEEE 802.11 standard that is networked by radio waves, typically configured as a wireless router. The wireless router can be networked by adopting a WiFi connection mode in an effective range covered by electric waves.

Bluetooth Low Energy (BLE) is a personal area network technology. BLE significantly reduces power consumption and cost compared to classical bluetooth while maintaining comparable communication range.

At present, the electronic device provided in the related art is generally provided with a WiFi component and a BLE component, and the configuration manner of the electronic device generally includes the following two types:

the mode I, the WiFi assembly and the BLE assembly are respectively arranged on two different chips, and each chip respectively corresponds to one antenna and works independently.

In this way, the WiFi component and the BLE component do not need to work in coordination and do not interfere with each other, and therefore, the communication performance is good. However, this approach has the drawbacks that: the hardware cost is higher with the dual-chip structure.

And the second mode, the WiFi assembly and the BLE assembly are integrated on the same chip and share the same antenna.

In this way, the WiFi component and the BLE component alternately operate in a time division multiplexing manner, and therefore, the hardware cost of a single integrated chip structure adopted in this manner is low. However, this approach has the drawbacks that: because the WiFi component and the BLE component work alternately in a time-sharing multiplexing mode, the requirement on cooperative control of the WiFi component and the BLE component is extremely high, otherwise, higher packet loss rate is caused.

In view of the above problems, no effective solution has been proposed.

In accordance with one embodiment of the present invention, there is provided an embodiment of a method for switching communication modes, where the steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer executable instructions, and where a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from the order shown.

In this embodiment, a method for switching a communication mode of the workstation is provided, and fig. 2 is a flowchart of a method for switching a communication mode according to an embodiment of the present invention, as shown in fig. 2, the method includes the following steps:

step S20, waking up a first communication component on first communication equipment according to a preset beacon interval, wherein the first communication component communicates with external communication equipment through second communication equipment in a first communication mode, and the second communication equipment is used for establishing a wireless local area network;

step S21, a beacon frame from the second communication device is intercepted by the first communication component, where the beacon frame carries at least first indication information, and the first indication information is used to indicate whether downlink data to be sent to the first communication device is stored on the second communication device;

step S22, switching between a first communication mode and a second communication mode according to the first indication information, wherein the second communication component of the first communication device performs peer-to-peer communication with the third communication device in the second communication mode.

Through the steps, a first communication component on a first communication device can be awakened according to a preset beacon interval, the first communication component communicates with an external communication device through a second communication device in a first communication mode, the second communication device is used for establishing a wireless local area network, a beacon frame from the second communication device is intercepted through the first communication component, at least first indication information is carried in the beacon frame, the first indication information is used for indicating whether downlink data to be sent to the first communication device is stored on the second communication device, switching is carried out between the first communication mode and the second communication mode according to the first indication information, the second communication component on the first communication device carries out point-to-point communication with a third communication device in the second communication mode, and the purpose of optimizing the cooperative working logic of the first communication component (such as a WiFi component) and the second communication component (such as a BLE component) is achieved, therefore, the technical effects of improving the communication stability (especially the stability of WiFi) of the electronic equipment, reducing the operation complexity of cooperative control of the WiFi assembly and the BLE assembly and reducing the packet loss rate caused by time-sharing multiplexing are achieved, and the technical problems that in the related art, the operation complexity of cooperative control of the WiFi assembly and the BLE assembly is high and the high packet loss rate is caused easily under the condition that the WiFi assembly and the BLE assembly are integrated on the same chip and work alternately in a time-sharing multiplexing mode are solved.

In the related art, in the process that the WiFi component and the BLE component alternately operate in a time division multiplexing mode, if the WiFi component is in an operating state, the BLE component is in a dormant state. Similarly, if the BLE component is in the active state, the WiFi component is in the sleep state. Therefore, the working method of time division multiplexing inevitably causes a high packet loss rate, and is also easy to cause a problem of disconnection. Taking the preset beacon interval as 100ms as an example, according to the time division multiplexing mode of the WiFi component and the BLE component adopted in the related art, in the first 100ms time range, the WiFi component is in a working state, and the BLE component is in a sleep state. In the second 100ms time frame, the BLE component is in an active state and the WiFi component is in a dormant state. The reciprocating and alternate execution is not repeated herein.

For this reason, with the power saving mode (power save mode) of IEEE 802.11, the WiFi component operating time is shortened as much as possible by the WiFi component low power consumption protocol, and most of the time is allocated to the BLE component for use.

IEEE 802.11power save mode is a standard WiFi low power protocol. Under the protocol, the WiFi state enters a power saving mode and turns off the RF module when there is no data to transmit or receive. The STATION is periodically woken up in a beacon interval (beacon interval) of the AP, thereby listening to beacon frames of the AP. The beacon frame of the AP is substantially a broadcast frame periodically transmitted by the AP, wherein the information carried in the broadcast frame may include, but is not limited to: the name of the AP (e.g., a Server Set Identifier (SSID)), the encryption method, and whether there is a flag (flag) for buffering data of each status associated with the AP on the AP, for example: a flag value (corresponding to first indication information) in a Traffic Indication Map (TIM).

Taking the status 1 in fig. 1 as an example, the status 1 wakes up the WiFi component on the status 1 at 100ms intervals. The WiFi assembly is communicated with external communication equipment (such as a mobile equipment control terminal such as a smart phone and a cloud server) through a WiFi AP in a WiFi working mode. STATION1 may listen for beacon frames from WiFi APs by the WiFi component. The beacon frame at least carries first indication information, and the first indication information is used for indicating whether downlink data to be sent to the state 1 is stored on the WiFi AP. And the state 1 switches between the WiFi operation mode and the BLE operation mode according to the first indication information. The BLE component on the STATION1 performs point-to-point communication with the BLE controller 1 in the BLE operating mode.

Fig. 3 is a schematic timing control diagram of a WiFi device and a BLE device according to an alternative embodiment of the present invention, and as shown in fig. 3, through an IEEE 802.11power save mode, the WiFi device on the state can be woken up once every 100ms, and the WiFi device set on the state is used to receive beacon frames and then immediately enters a sleep state, so as to achieve the purpose of saving power consumption of the WiFi device. Meanwhile, the downlink data sent to the state is cached on the AP, so the downlink data sent to the state is not lost. In addition, by utilizing the technical principle of the IEEE 802.11power save mode, the electronic device is switched to the BLE component operating mode at the timing of turning off the RF module of the WiFi component, thereby ensuring that the electronic device is in the BLE operating mode more than 90% of the time, and is in the WiFi operating mode only for a short time.

Optionally, in step S22, switching between the first communication mode and the second communication mode according to the first indication information may include the following steps:

step S220, determining that the downlink data to be sent to the first communication equipment is not stored on the second communication equipment according to the first indication information;

step S221, controlling the first communication component to enter a sleep state, and controlling the second communication component to enter a wake-up state, so that the first communication device is in the second communication mode.

Since all the downlink data to be sent to the status are cached in the AP in advance, when the AP does not store the cache data of the status, the TIM identifier representing the cache data in which the status does not exist may be set in the beacon frame. The TIM uses a Bitmap (Bitmap) structure to indicate whether or not downlink data of each state associated with an AP is cached on the AP. And each status checks the flag value at the corresponding position in the Bitmap through the Tim field in the beacon frame to determine whether corresponding downlink data is cached on the AP or not.

Table 1 is an optional example of using a Bitmap in the TIM to indicate whether downlink data addressed to the state is cached, as shown in table 1:

TABLE 1

STATION NO.	Beacon	Bitmap
			STATION
1	TIM flag 1	0
			STATION 2	TIM flag 2	1
STATION 3	TIM flag 3	1
			STATION 4	TIM flag 4	0
……	……	……
			STATION n-1	TIM flag n-1	1
STATION n	TIM flag n	0

Bitmaps in a TIM may typically be arranged in a matrix of M rows by N columns (M and N are positive integers). Each TIM flag corresponds to a different time. Taking table 1 as an example, state 1 corresponds to Tim flag 1 of the Tim field in the beacon frame, state 2 corresponds to Tim flag 2 of the Tim field in the beacon frame, state 3 corresponds to Tim flag 3 … of the Tim field in the beacon frame, and so on until state corresponds to Tim flag n of the Tim field in the beacon frame. If the value of the TIM flag is 1, indicating that downlink data corresponding to the TIME is cached on the AP; and if the value of the TIM flag is 0, indicating that the downlink data corresponding to the STATION is not cached on the AP. And when determining that downlink data corresponding to the status is not cached on the AP according to the value of the TIM flag, controlling the WiFi assembly to enter a dormant state, and controlling the BLE assembly to enter an awakening state so as to enable the status to be in a BLE working mode. For example: when determining that downlink data corresponding to the status 1 is not cached on the AP according to the value 0 of the TIM flag 1, the status 1 controls the WiFi component to enter a sleep state, and controls the BLE component to enter an awake state, so that the status 1 is in a BLE working mode.

step S222, determining that downlink data to be sent to the first communication equipment is stored on the second communication equipment according to the first indication information;

step S223, controlling the first communication component to keep the awake state, and controlling the second communication component to enter the sleep state, so that the first communication device is in the first communication mode.

Still as shown in table 1, when it is determined that downlink data corresponding to the status is cached on the AP according to the value of the TIM flag, the WiFi component is controlled to keep an awake state, and the BLE component is controlled to enter a sleep state, so that the status is in a WiFi operating mode. For example: when determining that the downlink data corresponding to the status 2 is cached on the AP according to the value 1 of the TIM flag 2, the status 2 controls the WiFi component to keep an awake state, and controls the BLE component to enter a sleep state, so that the status 2 is in a WiFi working mode.

Optionally, in step S22, after switching between the first communication mode and the second communication mode according to the first indication information, the method may further include the following steps:

step S23, sending a first null data frame to the second communication device, where the first null data frame carries second indication information, the second indication information is identified as a first value, and the first value is used to indicate that the first communication component is in an awake state;

step S24, receiving downlink data from the second communication device through the first communication component;

and step S25, executing corresponding control operation according to the downlink data.

The null data (nulrdata) frame is responsible for transmitting power saving state change information of the STATION to the AP. The STA (corresponding to the second indication information) is a field in the Nulldata frame, and notifies the AP of a power save state change of the STATION. Table 2 is an alternative example of using the STA to indicate a power saving state change of the state, as shown in table 2:

TABLE 2

STATION NO.	Nulldata No.	STA
			STATION
1	Nulldata 1	0-represents work
			STATION 2	Nulldata 2	1-indicates sleep
STATION 3	Nulldata 3	1
			STATION 4	Nulldata 4	0
……	……	……
			STATION n-1	Nulldata n-1	1
STATION n	Nulldata n	0

Taking the state 1 as an example, firstly, the state 1 sends Nulldata1 to the AP, where a value of an STA field carried by the Nulldata1 is 0, which indicates that the state 1 is in the WiFi operating mode. Second, the status 1 receives downlink data from the AP through the WiFi component. And then the state 1 executes corresponding control operation according to the downlink data. The following describes, in conjunction with a plurality of application scenarios, the execution of corresponding control operations by the STATION1 according to downlink data:

in an application scenario I, it is assumed that the state 1 is an intelligent lamp, and the downlink data is control information that the intelligent lamp needs to be automatically turned on at 6 o 'clock at night through the cloud server, so that the state 1 can be automatically turned on at 6 o' clock at night according to the downlink data.

In an application scenario two, if the state 1 is an intelligent lamp, downlink data is control information that the intelligent lamp needs to be automatically turned on immediately when a user opens a door and enters a room, which is detected by other intelligent household equipment (such as an intelligent security door), the state 1 is automatically turned on immediately according to the downlink data to illuminate the user.

And in an application scene three, assuming that the state 1 is an intelligent lamp, and the downlink data is control information that a user needs to enter a reading mode or a cinema mode through the brightness adjustment of the intelligent lamp set by the smart phone, the state 1 adjusts the light brightness according to the reading mode or the cinema mode according to the downlink data.

Optionally, in step S23, after sending the first null data frame to the second communication device, the method may further include the following steps:

step S26, under the condition that the downlink data is determined to be received completely, controlling the first communication component to enter a dormant state and controlling the second communication component to enter a wake-up state, so that the first communication device is in a second communication mode;

step S27, sending a second null data frame to the second communication device, where the second null data frame carries second indication information, and the second indication information is identified as a second value, where the second value is used to indicate that the first communication component is in a dormant state.

Taking the status 2 as an example, in the case that the status 2 determines that the downlink data reception is completed, the status 2 controls the WiFi component to enter the sleep state, and controls the BLE component to enter the wake state, so that the status 2 is in the BLE operating mode. Then, the STATION2 sends Nulldata 2 to the AP, where a value of an STA field carried by the Nulldata 2 is 1, which indicates that the STATION2 is in a BLE operating mode.

Optionally, the method may further include the following steps:

step S28, a broadcast frame from the third communication device is intercepted through the second communication component, wherein the broadcast frame carries a control instruction;

and step S29, executing corresponding control operation according to the control instruction.

While the WiFi component remains connected, the BLE component on the STATION can still listen for broadcast frames from the BLE controller without having to establish a connection and synchronization. The broadcast frame carries control instructions. The state executes a corresponding control operation according to the control instruction.

Assuming that the state is an intelligent lamp, and the BLE controller is a remote controller matched with the intelligent lamp, a control instruction for turning on the lamp can be sent to the intelligent lamp through the remote controller, and then the intelligent lamp executes a corresponding operation for turning on the lamp according to the control instruction. Similarly, the remote controller can send a light-off control instruction to the intelligent electric lamp, and then the intelligent electric lamp executes corresponding light-off operation according to the control instruction.

Optionally, in step S28, listening for the broadcast frame by the second communicating component may include performing the following steps:

step S281, the second communication device listens to the broadcast frame via a predetermined channel, wherein the predetermined channel is selected from a plurality of candidate channels and is determined by a negotiation between the first communication device and the third communication device.

The broadcasting process of the BLE component may originally work on a plurality of different channels (channels), and therefore, in order to improve the success rate of the BLE component for receiving data, the broadcasting process of the BLE component may be fixed on any one of the channels. As to which channel is actually fixed, it needs to be determined by each STATION and the corresponding BLE controller through negotiation in advance, so that each STATION listens to the broadcast frame from the corresponding BLE controller via the fixed channel.

Optionally, the beacon frame further carries an updated beacon interval, and after listening to the beacon frame by the first communication component in step S21, the method may further include the following steps:

step S30, adjusting the preset beacon interval to the updated beacon interval, and waking up the first communication component again according to the updated beacon interval.

In general, the AP transmits a beacon frame once according to beacon interval (e.g., 100 ms). The preset duration can be self-defined and adjusted by a user to obtain an updated beacon interval. Then, the AP will carry the updated beacon interval in the beacon frame and send the beacon frame to the state, so that the state wakes up the WiFi component according to the updated beacon interval.

There is also provided, in accordance with an embodiment of the present invention, an embodiment of a method for processing a broadcast frame, including the steps illustrated in the flowchart of the figure as being executable by a computer system, such as a set of computer-executable instructions, and although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be executed in an order different than that illustrated or described herein.

In this embodiment, a method for processing a broadcast frame operating in the BLE controller is provided, and fig. 4 is a flowchart of a method for processing a broadcast frame according to an embodiment of the present invention, as shown in fig. 4, the method includes the following steps:

step S40, determining that the first communication device is switched from a first communication mode to a second communication mode, wherein the first communication device communicates with an external communication device through a second communication device in the first communication mode, the second communication device is used for establishing a wireless local area network, and the first communication device communicates with a third communication device point-to-point in the second communication mode;

step S41, responding to the control operation acted on the third communication equipment, and determining a control instruction to be sent;

step S42, repeatedly sending a broadcast frame to the first communication device within a preset time duration, where the broadcast frame carries a control instruction.

In order to reduce the packet loss probability of the BLE component, a retransmission mechanism is newly added at the end of the BLE controller, so that it is ensured that the control instruction of the BLE controller can be retransmitted for multiple times within a preset time period, and the probability that the BLE control instruction is received by the STATION is obviously improved. The control operation of the BLE controller can be completed by a physical control keyboard consisting of physical keys, a virtual control keyboard consisting of virtual keys on a touch display screen, and a physical touch panel matched with the display screen. When the BLE controller detects that a user performs pressing operation on a physical key, or touch operation performed on a touch display screen, or touch operation performed on a touch panel, the BLE controller determines a BLE control instruction (such as a light-on instruction) to be sent. Then, the BLE controller repeatedly sends the BLE control instruction to the STATION for a preset time length.

In an alternative embodiment, the predetermined duration is greater than the predetermined beacon interval.

In order to ensure that the STATION successfully receives the BLE controller transmission control instruction, the continuous retransmission time may be controlled to be greater than a preset beacon interval (e.g., 100 ms). Of course, the preset time length may also be set to be less than or equal to 100ms according to the actual application scenario.

Optionally, in step S42, the repeatedly sending the broadcast frame to the first communication device within the preset time period may include the following steps:

step S420, repeatedly sending a broadcast frame to the first communication device via a preset channel within a preset time period, where the preset channel is selected from a plurality of candidate channels and is determined by negotiation between the first communication device and the third communication device in advance.

The broadcasting process of the BLE component may originally work on a plurality of different channels, and therefore, in order to improve the success rate of the BLE component for receiving data, the broadcasting process of the BLE component may be fixed on any one of the channels. As to which channel is actually fixed, it needs to be determined by each STATION and the corresponding BLE controller through negotiation in advance, so that each STATION listens to the broadcast frame from the corresponding BLE controller via the fixed channel.

In an optional embodiment, the BLE controller may repeatedly send the broadcast frame to the corresponding STATION at equal time intervals via the fixed channel for a preset time period. For example, when the preset time duration is 100ms, the BLE controller repeatedly transmits 10 broadcast frames to the corresponding STATION at time intervals of 10 ms. Of course, the BLE controller may not repeatedly transmit the broadcast frame to the corresponding state at equal time intervals. For example, when the preset duration is 100ms, the BLE controller repeatedly transmits the broadcast frame to the corresponding STATION 4 times in 10ms, 30ms, 60ms, and 100ms, respectively.

Optionally, in step S42, after the broadcast frame is repeatedly sent to the first communication device within the preset time period, the method may further include the following steps:

in step S43, if a feedback message is received from the first communication device within the preset time period, the broadcast frame is stopped from being transmitted before the end time of the preset time period is reached, where the feedback message is used to indicate that the first communication device has successfully executed the control instruction.

In order to enable the first communication device to timely and accurately receive the control instruction carried in the broadcast frame, the third communication device repeatedly sends the broadcast frame to the first communication device within a preset time length. In order to effectively save or reduce the power consumption of the third communication device, a feedback mechanism may be added to the first communication device.

In an alternative embodiment, the feedback message may be used to indicate that the first communication device has successfully executed the control instruction. If the first communication device has received the control instruction from the third communication device and the first communication device successfully executes the control instruction, the first communication device may send a feedback message to the third communication device so that the third communication device can determine that the first communication device has successfully executed the control instruction. Therefore, the third communication equipment does not need to repeatedly broadcast the frame to the first communication equipment, and the power consumption of the third communication equipment can be effectively saved or reduced.

In an alternative embodiment, the feedback message may also be used to indicate that the first communication device failed to execute the control instruction. If the first communication device has received the control instruction from the third communication device but the first communication device fails to execute the control instruction successfully, the first communication device may still send a feedback message to the third communication device so that the third communication device can determine that the first communication device fails to execute the control instruction successfully. Thus, the third communication device can broadcast the frame to the first communication device again in a targeted manner.

in step S44, if a feedback message from the first communication device is not received when the end time of the preset duration is reached, the broadcast frame is stopped from being transmitted and the first communication device enters the sleep state, where the feedback message is used to indicate that the first communication device has successfully executed the control instruction.

In an alternative embodiment, the feedback message may be used to indicate that the first communication device has successfully executed the control instruction. If the third communication device does not receive the feedback message from the first communication device when the end time of the preset duration is reached, the third communication device may stop repeatedly sending the broadcast frame and enter a sleep state (i.e., a low power consumption state), so that power consumption of the third communication device can be effectively saved or reduced.

The overall operation flow of the communication mode switching system will be described in further detail with reference to the alternative embodiment shown in fig. 5. Fig. 5 is a flowchart illustrating an operation of the system for switching communication modes according to an alternative embodiment of the present invention. As shown in fig. 5, the process may include the following process steps:

step S502, the WiFi AP sends a beacon frame to the STATION, wherein the beacon frame carries a beacon interval, a TIM field and an SSID field. And the value of the TIM flag corresponding to the STATION in the TIM field is 0, which indicates that the STATION enters a BLE working mode.

In step S504, the state receives a lighting control command from the BLE controller.

Step S506, the WiFi AP sends beacon frame to the STATION, where the beacon frame carries beacon interval, TIM field, and SSID field. And the value of the TIM flag corresponding to the STATION in the TIM field is 1, which indicates that the STATION enters the WiFi working mode.

Step S508, the STATION sends a Nulldata frame to the WiFi AP, where the Nulldata frame carries an STA field. And the attribute value of the STA field is 0, and the WiFi AP is informed that the STATION enters the WiFi working mode, so that the WiFi AP sends the content which is stored in the WiFi AP and is associated with the STATION to the STATION.

In step S510, the WiFi AP sends the content associated with the status stored in the WiFi AP to the status.

In step S512, the WiFi AP clears the content associated with the status stored in the WiFi AP.

Step S514, the STATION sends a Nulldata frame to the WiFi AP, wherein the Nulldata frame carries the STA field. And the attribute value of the STA field is 1, and the WiFi AP is informed that the STATION enters the BLE working mode.

Step S516, the WiFi AP sends beacon frame to the STATION, where the beacon frame carries beacon interval, TIM field, and SSID field. And the value of the TIM flag corresponding to the STATION in the TIM field is 0, which indicates that the STATION enters a BLE working mode.

In step S518, the state receives other control instructions (e.g., adjusting the light intensity, turning off the light) from the BLE controller.
