Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The communication method, the device, the electronic equipment and the storage medium provided by the embodiment of the application are described in detail through specific embodiments and application scenes thereof with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a communication method, which is applied to a first terminal device, and includes:
the method provided by the embodiment of the application is applied to first terminal equipment, wherein the first terminal equipment is Bluetooth equipment, such as Bluetooth headphones, a bracelet and the like, or mobile terminals with Bluetooth functions, such as smart phones, personal computers, tablet computers or wearable smart equipment and the like.
The second terminal device is a Bluetooth device or a mobile terminal with Bluetooth function.
The first terminal device and the second terminal device start Bluetooth, and Bluetooth communication is directly carried out between the first terminal device and the second terminal device. I.e. the first signal is a bluetooth signal.
Because bluetooth's power is low, lead to bluetooth's coverage very little, in the communication distance between first terminal equipment and the second terminal equipment great, or have the scene of barrier, bluetooth communication is unstable. Therefore, the Wifi router is used as a bluetooth relay between the first terminal device and the second terminal device.
As Wifi network coverage is becoming more and more popular, many public places, such as subways, buses, squares and markets, have Wifi network coverage. Therefore, the Wifi router has great practical value as a Bluetooth relay.
The first terminal device and the second terminal device are co-frequency with 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 communication process between the first terminal device and the second terminal device and the Wifi router is as follows:
1. the first terminal equipment simultaneously sends a first signal P0 to the second terminal equipment and the Wifi router;
2. after the first signal P0 is received by the Wifi router, the Wifi router amplifies the first signal P0, takes the amplified first signal P0 as a second signal P1, and sends the second signal P1 to the second terminal equipment;
3. The second terminal equipment receives the first signal P0 and the second signal P1 successively, compares the signal intensity of the first signal P0 with the signal intensity of the second signal P1, and demodulates the signal with large signal intensity. Wherein the signal strength is characterized by the level of the signal, the greater the level, the greater the signal strength.
The propagation of the first signal P0 is due to multipath effects, the signal arriving from the first terminal device to the second terminal device being actually the result of the superposition of a plurality of signals.
As shown in fig. 2, the first signal P0 arrives at the second terminal device B from the first terminal device a through two paths, and is directly sent to the second terminal device B by the first terminal device a, or is forwarded to the second terminal device B via the Wifi router.
The relay function of the Wifi router is equivalent to increasing the signal energy of the first signal P0 in a certain path, so that the signal power of the signal received by the second terminal device is improved.
The hardware block diagram of the Wifi router is shown in fig. 3, and the Wifi router includes an antenna, a filter, a Wifi transceiver, a Wifi ap internal buffer, and a PA (Power Amplifier).
The receiving process of the Wifi router on the first signal P0 includes: the first signal P0 is received by an antenna of the Wifi router, filtered by a filter and then input into a Wifi transceiver of the Wifi router. The Wifi transceiver down-converts the radio frequency signal into a baseband signal and then caches the baseband signal.
The transmitting process of the Wifi router to the first signal P0 includes: the Wifi transceiver up-converts the baseband signal in the buffer memory into a radio frequency signal, and the radio frequency signal is amplified by the PA, filtered by the filter and then transmitted to the second terminal equipment through the antenna.
According to the embodiment of the application, the hardware circuit of the Wifi router is fully utilized, and the amplification and up-down conversion of the first signal P0 are processed by the radio frequency front-end circuit of the Wifi router. And a professional Bluetooth chip is not needed, and the cost of a hardware circuit is not increased additionally.
The second signal P1 is a signal amplified by the Wifi router, but the signal strength of the second signal P1 received by the second terminal device is not necessarily greater than the signal strength of the first signal P0.
For example, as shown in fig. 4, in the case where the distance between the Wifi router and the second terminal device B is far greater than the distance between the first terminal device a and the second terminal device B, the signal strength of P1 may be smaller than that of P0.
As shown in fig. 5, in the case where 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.
Demodulating P1 in case P1 is greater than P0; in the case where P1 is smaller than P0, P0 is demodulated.
According to the embodiment of the application, the wifi router is used as a Bluetooth relay, the signal transmitted by the first terminal equipment is amplified by the signal amplification function of the wifi router, the amplified signal is demodulated under the condition that the amplified signal is larger than the signal intensity of the original signal, the coverage range of Bluetooth is enlarged under the condition that Bluetooth power consumption is not changed, and additional professional equipment is not needed.
Optionally, before the second signal is sent to the second terminal device after the first signal is amplified by the Wifi router through the Wifi connection, the method further includes: displaying prompt information of amplifying and forwarding signals through a Wifi router under the condition that the Wifi router with the same frequency as the first terminal equipment exists in the preset range of the first terminal equipment;
and when the first terminal equipment and the second terminal equipment establish Bluetooth connection, the first terminal equipment detects whether a Wifi router exists in a preset range. The preset range is preset according to actual needs.
And the existing Wifi router and the first terminal equipment have the same frequency, so that the Wifi router and the first terminal equipment can communicate.
And under the condition that the Wifi router with the same frequency as the first terminal equipment is detected, the first terminal equipment sends and displays prompt information. The prompt message is used for prompting the user to amplify the first signal by connecting with the Wifi router. The display interface of the prompt message is shown in fig. 6.
Receiving a first input; and responding to the first input, and sending a request for establishing communication connection to the Wifi router so as to establish the Wifi connection.
The first input may be in the form of a mouse click operation or a keyboard input operation, and embodiments of the present application are not limited to the 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 message, a request for establishing a communication connection is sent to the Wifi router to establish the Wifi connection.
As shown in fig. 7, when a plurality of Wifi routers with the same frequency as the first terminal device exist in a preset range of the first terminal device, related information of the Wifi routers is also displayed on a display interface of the prompt information.
The related information of the Wifi router comprises the name and signal strength of the Wifi router, such as the name of the Wifi router is a Wifi router 1 and a Wifi router 2.
The user clicks the yes button on the display interface of the prompt message and also needs to select the Wifi router. And sending a request for establishing communication connection to the Wifi router selected by the user according to clicking and selecting operations of the user so as to establish Wifi connection.
The first terminal device supports both Bluetooth and Wifi. When the Wifi router is used as a Bluetooth relay, the first terminal device sends a control instruction to the Wifi router, and Wifi connection is established. The control instruction is a Wifi signal.
The Wifi router monitors signals sent by the first terminal equipment. Whether the signal is a Bluetooth signal or a Wifi signal is judged through the bandwidth of the signal, if the Bluetooth signal is 1M bandwidth, wifi is 20M bandwidth, and only the Bluetooth signal is guaranteed to be amplified.
According to the embodiment of the application, the prompt information is displayed under the condition that the Wifi router with the same frequency as the first terminal equipment exists in the preset range of the first terminal equipment, so that a user can conveniently perform Wifi connection operation according to the prompt information.
Optionally, the sending a request for establishing a communication connection to the Wifi router includes:
and sending a request for establishing communication connection to the Wifi router under the condition that the received power corresponding to the signal sent through the Bluetooth connection is smaller than a preset threshold value.
The signals sent through the Bluetooth connection comprise signals sent by the first terminal equipment A and the second terminal equipment B through the Bluetooth connection.
After the Bluetooth connection is established between the A and the B, when the A determines that the receiving power of the signal sent by the A or the B is smaller than the preset threshold Pb, the A sends a request for establishing communication connection to the Wifi router so as to establish the communication connection between the A and the Wifi router, a signal amplifying function is started, and the first signal sent by the A is amplified.
According to the embodiment of the application, the Wifi router is used as the Bluetooth relay only under the condition that the receiving power corresponding to the signal sent by the Bluetooth connection is smaller, so that effective utilization of resources is realized.
Optionally, the method further comprises: and sending a transmission delay corresponding to the data forwarding through the Wifi router to the second terminal equipment, wherein the transmission delay is used for indicating the second terminal equipment to receive the second signal after the second terminal equipment passes through the transmission delay.
Since the bluetooth signal is a time division signal, the first terminal device and the second terminal device cannot transmit signals at the same time. Therefore, after 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 Wifi router to forward the first signal P0. The second terminal device receives the second signal after t1. The second signal is received before the signal transmission is performed.
As shown in fig. 8, in the case that neither the first terminal device a nor the second terminal device B passes through the Wifi router, a directly transmits a signal to B, and B simultaneously receives a signal. Then B sends a signal directly to a, which receives the signal simultaneously. TX means transmit and RX means receive.
As shown in fig. 9, in the case where both the first terminal device a and the second terminal device B pass through the Wifi router, a transmits a signal to B through the Wifi router, generating a transmission delay t1, resulting in delay of B reception and transmission signals by t1, and delay of a reception signal of a corresponding to the transmission signal of B by t1.
And then B sends a signal to A through the Wifi router, the transmission delay t2 is generated, and the received signal of A corresponding to the sent signal of B continues to be delayed by t2, namely, the received signal of A is delayed by t1+t2 in total.
According to the method and the device, the transmission delay corresponding to the data forwarding through the Wifi router is sent to the second terminal equipment, the second terminal equipment is instructed to receive signals after the transmission delay, then the signals are sent, the first terminal equipment and the second terminal equipment are prevented from sending signals at the same time, and the communication quality is improved.
Optionally, the method further comprises: 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 packet, the greater the transmission delay for forwarding data via the Wifi router.
The embodiment of the application realizes accurate determination of the transmission delay, thereby indicating the second terminal equipment to receive the signal after the transmission delay, better avoiding the first terminal equipment and the second terminal equipment from simultaneously transmitting the signal and improving the communication quality.
As shown in fig. 10, the complete steps of the communication method in the embodiment of the present application are as follows:
1. the method comprises the steps that a first terminal device A and a second terminal device B establish Bluetooth connection;
2. the method comprises the steps that a first terminal device A monitors whether a Wifi router with the same frequency as the first terminal device A exists in a preset range of the first terminal device A;
if the wireless communication system does not exist, the A and the B directly carry out Bluetooth communication without passing through a Wifi router;
if yes, prompting the user to connect with the Wifi router;
3. after the A is connected with the Wifi router, detecting whether the receiving power corresponding to the signal sent by the A or the B is smaller than a preset threshold Pb or not;
if not, the A and the B directly carry out Bluetooth communication without passing through a Wifi router;
if yes, the A commands the Wifi router to start a Bluetooth signal amplifying function, and the B agrees with the transmission delay t1;
4. the P0 sent by the A is amplified by a Wifi router and then becomes a second signal P1, and the P1 is sent to the B through the Wifi router; meanwhile, the A directly sends P0 to the B;
5. b judges whether P0 is smaller than P1, and demodulates the larger one.
