Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific sequence or sequence. It is to be understood that the data so used can be interchanged under appropriate circumstances such that the embodiments of the application can be practiced in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.

The communication method, device, electronic device, and storage medium provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

As shown in Figure 1, this embodiment of the present application provides a communication method, which is applied to a first terminal device, and the method includes:

Step 101, the first terminal device sends a first signal to the second terminal device through a Bluetooth connection;

The method provided in the embodiment of this application is applied to a first terminal device, which is a Bluetooth device, such as a Bluetooth headset, a wristband, etc., or a mobile terminal with a Bluetooth function, such as a smart phone, a personal computer, a tablet computer or a Wear smart devices, etc.

The second terminal device is a bluetooth device or a mobile terminal with a bluetooth function.

The first terminal device and the second terminal device turn on Bluetooth, and directly perform Bluetooth communication between the two. That is, the first signal is a Bluetooth signal.

Step 102, after amplifying the first signal via a Wifi router through a Wifi connection, sending a second signal to the second terminal device, the second signal is determined by the second terminal device after determining the signal of the second signal Demodulation is performed when the signal strength is greater than the signal strength of the first signal; wherein the first signal and the second signal carry the same data packet.

Due to the low power of the Bluetooth, the coverage of the Bluetooth is very small, and the Bluetooth communication is unstable when the communication distance between the first terminal device and the second terminal device is relatively large or there are obstacles. Therefore, the Wifi router is used as a Bluetooth relay between the first terminal device and the second terminal device.

Due to the increasing popularity of Wifi network coverage, many public places, such as subways, buses, squares and shopping malls, have Wifi network coverage. Therefore, using a Wifi router as a Bluetooth relay has great practical value.

The first terminal device and the second terminal device have the same frequency as the Wifi router, for example, all three use a 2.4G network, so that the first terminal device and the second terminal device can communicate with the Wifi router.

The process that the first terminal device and the second terminal device communicate with the Wifi router is as follows:

1. The first terminal device simultaneously sends the first signal P0 to the second terminal device and the Wifi router;

2. After the first signal P0 is received by the Wifi router, the Wifi router amplifies the first signal P0, uses the amplified first signal P0 as the second signal P1, and sends the second signal P1 to the second terminal device;

3. The second terminal device successively receives the first signal P0 and the second signal P1, compares the signal strength of P0 with the signal strength of P1, and demodulates the signal with higher signal strength. Wherein, the signal strength is characterized by the level of the signal, and the greater the level, the greater the signal strength.

Since the propagation of the first signal P0 is affected by the multipath effect, the signal reaching the second terminal device from the first terminal device is actually the result of the superposition of multiple signals.

As shown in Figure 2, the first signal P0 reaches the second terminal device B through two paths from the first terminal device A, and is directly sent by the first terminal device A to the second terminal device B, or forwarded to the second terminal device B via a Wifi router. terminal device B.

The relay function of the Wifi router is equivalent to increasing the signal energy of the first signal P0 under a certain path, so that the signal power of the signal received by the second terminal device is increased.

The hardware block diagram of the Wifi router is shown in Figure 3. The Wifi router includes an antenna, a filter, a Wifi transceiver, a WifiAP internal cache, and a PA (Power Amplifier, power amplifier).

The process of receiving the first signal P0 by the Wifi router includes: the first signal P0 is received by the antenna of the Wifi router, filtered by a filter, and then input to the Wifi transceiver of the Wifi router. The Wifi transceiver down-converts the RF signal to a baseband signal and buffers it.

The transmission process of the first signal P0 by the Wifi router includes: the Wifi transceiver up-converts the baseband signal in the cache into a radio frequency signal, amplifies by the PA, filters it with a filter, and sends it to the second terminal device through the antenna.

The embodiment of the present application makes full use of the hardware circuit of the Wifi router, and the amplification and up-down conversion of the first signal P0 is completely multiplexed with the radio frequency front-end circuit of the Wifi router for processing. No professional bluetooth chip is required, no additional hardware circuit cost is required.

Although the second signal P1 is the amplified signal of the first signal P0 through the Wifi router, the signal strength of P1 received by the second terminal device is not necessarily greater than the signal strength of P0.

For example, as shown in Figure 4, when the distance between the Wifi router and the second terminal device B is much greater than the distance between the first terminal device A and the second terminal device B, the signal strength of P1 may be stronger than that of P0 The signal strength is low.

As shown in FIG. 5 , when there is an obstacle in the path from the Wifi router to the second terminal device B, the signal strength of P1 may be smaller than that of P0 .

When P1 is greater than P0, P1 is demodulated; when P1 is smaller than P0, P0 is demodulated.

In the embodiment of the present application, by using the wifi router as a Bluetooth relay, the signal amplification function of the wifi router is used to amplify the signal sent by the first terminal device, and when the signal strength of the amplified signal is greater than that of the original signal, the amplified signal is decomposed. Adjustment, without changing the Bluetooth power consumption, expand the coverage of Bluetooth, and does not require additional professional equipment.

Optionally, before sending the second signal to the second terminal device after amplifying the first signal via a Wifi router through the Wifi connection, the method further includes: within a preset range of the first terminal device If there is a Wifi router with the same frequency as the first terminal device in the internal memory, display a prompt message for amplifying and forwarding the signal via the Wifi router;

While the first terminal device and the second terminal device establish a Bluetooth connection, the first terminal device detects whether there is a Wifi router within a preset range. The preset range is preset according to actual needs.

Moreover, the existing Wifi router and the first terminal device have the same frequency, so that the Wifi router and the first terminal device can communicate.

When a Wifi router with the same frequency as the first terminal device is detected, the first terminal device sends and displays prompt information. The prompt information is used to prompt the user to connect to the Wifi router to amplify the first signal. The display interface of the prompt information is shown in FIG. 6 .

receiving a first input; in response to the first input, sending a request for establishing a communication connection to the Wifi router, so as to establish the Wifi connection.

The form of the first input may be a mouse click operation or a keyboard input operation, and this embodiment of the present application is not limited to a specific form of the first input.

As shown in FIG. 6 , when the user clicks the "Yes" button on the display interface of the prompt information, a request for establishing a communication connection is sent to the Wifi router to establish a Wifi connection.

As shown in Figure 7, when there are multiple Wifi routers with the same frequency as the first terminal equipment within the preset range of the first terminal equipment, the relevant information of the Wifi routers is also displayed on the display interface of the prompt information .

The relevant information of the Wifi router includes the name and signal strength of the Wifi router, for example, the names of the Wifi router are Wifi router 1 and Wifi router 2.

When the user clicks the "Yes" button on the display interface of the prompt information, the Wifi router also needs to be selected. According to the click and selection operation of the user, a request for establishing a communication connection is sent to the Wifi router selected by the user, so as to establish a Wifi connection.

The first terminal device supports both bluetooth and Wifi. When the Wifi router acts as a Bluetooth relay, the first terminal device sends a control command to the Wifi router to establish a Wifi connection. The control command is Wifi signal.

The Wifi router listens to the signal sent by the first terminal device. Determine whether the signal is a Bluetooth signal or a Wifi signal by the bandwidth of the signal. For example, the Bluetooth signal has a bandwidth of 1M, and the Wifi signal has a bandwidth of 20M, ensuring that only the Bluetooth signal is amplified.

In the embodiment of the present application, when there is a Wifi router with the same frequency as the first terminal device within the preset range of the first terminal device, prompt information is displayed, so as to facilitate the user to perform Wifi connection operations according to the prompt information.

Optionally, the sending a request for establishing a communication connection to the Wifi router includes:

When it is determined that the received power corresponding to the signal sent through the Bluetooth connection is less than a preset threshold, a request for establishing a communication connection is sent to the Wifi router.

Wherein, the signal sent through the Bluetooth connection includes the signal sent by the first terminal device A and the second terminal device B through the Bluetooth connection.

After A and B establish the Bluetooth connection, when A determines that the received power of the signal sent by A or B is less than the preset threshold Pb, A sends a request to establish a communication connection to the Wifi router to establish a communication connection between A and the Wifi router, Turn on the signal amplification function to amplify the first signal sent by A.

In the embodiment of the present application, the Wifi router is used as the Bluetooth relay only when the receiving power corresponding to the signal sent by the Bluetooth connection is small, so as to realize effective utilization of resources.

Optionally, the method further includes: sending to the second terminal device a transmission delay corresponding to data forwarding via the Wifi router, where the transmission delay is used to indicate that the second terminal device passes through the transmission delay Then the second signal is received.

Since the Bluetooth signal is a time-division signal, the first terminal device and the second terminal device cannot send signals at the same time. Therefore, when the Wifi router is used as the Bluetooth relay, the first terminal device and the second terminal device need to agree on a transmission delay t1 corresponding to the forwarding of the first signal P0 by the Wifi router. The second terminal device does not receive the second signal until t1 has elapsed. After the second signal is received, the signal is then sent.

As shown in FIG. 8 , when both the first terminal device A and the second terminal device B do not pass through the Wifi router, A directly sends a signal to B, and B receives the signal at the same time. Then B directly sends a signal to A, and A receives the signal at the same time. TX means send and RX means receive.

As shown in Figure 9, when both the first terminal device A and the second terminal device B pass through the Wifi router, A sends a signal to B through the Wifi router, resulting in a transmission delay of t1, resulting in a delay of t1 in receiving and sending signals from B, and B The corresponding received signal of A is also delayed by t1.

Then B sends a signal to A through the Wifi router, resulting in a transmission delay of t2, and the received signal of A corresponding to B's sent signal continues to be delayed by t2, that is, the total delay of A's received signal is t1+t2.

In this embodiment of the present application, by sending the transmission delay corresponding to the data forwarding via the Wifi router to the second terminal device, instructing the second terminal device to receive the signal after the transmission delay, and then to send the signal, avoiding the first terminal device and the second terminal device. Terminal devices send signals at the same time, improving communication quality.

Optionally, the method further includes: determining the transmission delay based on the size of the data packet.

The transmission delay is determined according to the size of the data packet sent by the first terminal device to the second terminal device. The larger the data packet, the greater the transmission delay for data forwarding via the Wifi router.

The embodiment of the present application realizes accurate determination of the transmission delay, thereby instructing the second terminal device to receive the signal after the transmission delay, better preventing the first terminal device and the second terminal device from sending signals at the same time, and improving communication quality.

As shown in Figure 10, the complete steps of the communication method in the embodiment of the present application are as follows:

1. The first terminal device A and the second terminal device B establish a Bluetooth connection;

2. The first terminal device A monitors whether there is a Wifi router with the same frequency as the first terminal device A within the preset range of the first terminal device A;

If it does not exist, then A and B communicate directly through Bluetooth without going through the Wifi router;

If it exists, prompt the user to connect to the Wifi router;

3. After A connects to the Wifi router, it detects whether the receiving power corresponding to the signal sent by A or B is less than the preset threshold Pb;

If not, then A and B directly communicate with Bluetooth without going through the Wifi router;

If so, then A orders the Wifi router to enable the Bluetooth signal amplification function, and agrees with B on the transmission delay t1;

4. The P0 sent by A becomes the second signal P1 after being amplified by the Wifi router, and sends P1 to the standby B through the Wifi router; at the same time, A directly sends P0 to B;

5. B judges whether P0 is smaller than P1, and demodulates the larger one.

As shown in Figure 11, the embodiment of the present application provides a communication method, which is applied to a second terminal device, and the method includes:

Step 1101, receiving a first signal sent by a first terminal device through a Bluetooth connection, and receiving a second signal sent by the first terminal device after amplifying the first signal through a Wifi router through a Wifi connection;

The method provided in the embodiment of the present application is applied to a second terminal device, which is a Bluetooth device, such as a Bluetooth headset, a wristband, etc., or a mobile terminal with a Bluetooth function, such as a smart phone, a personal computer, a tablet computer or a Wear smart devices, etc.

The first terminal device is a bluetooth device or a mobile terminal with a bluetooth function.

The first terminal device and the second terminal device turn on Bluetooth, and directly perform Bluetooth communication between the two. That is, the first signal is a Bluetooth signal.

Due to the low power of the Bluetooth, the coverage of the Bluetooth is very small, and the Bluetooth communication is unstable when the communication distance between the first terminal device and the second terminal device is relatively large or there are obstacles. Therefore, the Wifi router is used as a Bluetooth relay between the first terminal device and the second terminal device.

The first terminal device and the second terminal device have the same frequency as the Wifi router, for example, all three use a 2.4G network, so that the first terminal device and the second terminal device can communicate with the Wifi router.

The second terminal device receives the first signal P0 sent by the first terminal device through two paths. One path is to directly receive the first signal P0 sent by the first terminal device; the other path is to amplify the first signal P0 sent by the first terminal device into the second signal P1 after being amplified by the Wifi router, and receive the second signal sent by the Wifi router P1.

Step 1102, if it is determined that the signal strength of the second signal is greater than the signal strength of the first signal, demodulate the second signal; wherein, the first signal and the second signal carry same packet.

Although the second signal P1 is the amplified signal of the first signal P0 through the Wifi router, the signal strength of P1 received by the second terminal device is not necessarily greater than the signal strength of P0.

For example, when the distance between the Wifi router and the second terminal device is much greater than the distance between the first terminal device and the second terminal device, or there is an obstacle between the Wifi router and the second terminal device, the signal of P1 The intensity may be less than the signal intensity of P0.

The second terminal compares P0 and P1. When P1 is greater than P0, P1 is demodulated; when P1 is smaller than P0, P0 is demodulated.

In this embodiment of the present application, the wifi router is used as a Bluetooth relay, and the signal amplification function of the wifi router is used to amplify the signal sent by the first terminal device. When the signal strength of the amplified signal is greater than that of the original signal, the second terminal device amplifies Amplify the signal for demodulation, expand the coverage of Bluetooth without changing the power consumption of Bluetooth, and do not require additional professional equipment.

Optionally, the method further includes: receiving a transmission delay corresponding to data forwarding via the Wifi router sent by the first terminal device, and performing signal reception after the transmission delay passes.

Since the Bluetooth signal is a time-division signal, the first terminal device and the second terminal device cannot send signals at the same time. Therefore, when the Wifi router is used as the Bluetooth relay, the first terminal device and the second terminal device need to agree on a transmission delay t1 corresponding to the forwarding of the first signal P0 by the Wifi router.

After receiving the transmission delay t1 sent by the first terminal device, the second terminal device receives the signal after t1 has elapsed. The second terminal does not send the signal until after the signal has been received.

In this embodiment of the present application, the second terminal device receives the transmission delay corresponding to the data forwarding via the Wifi router sent by the first terminal device, receives the signal after the transmission delay, and then sends the signal, avoiding the first terminal device and the second terminal device. Terminal devices send signals at the same time, improving communication quality.

Optionally, the transmission delay is determined based on the size of the data packet.

The transmission delay is determined according to the size of the data packet sent by the first terminal device to the second terminal device. The larger the data packet, the greater the transmission delay for data forwarding via the Wifi router.

The embodiment of the present application realizes accurate determination of the transmission delay, so that the second terminal device receives signals after the transmission delay, better avoids simultaneous transmission of signals by the first terminal device and the second terminal device, and improves communication quality.
