Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The communication method, the apparatus, the electronic device and the storage medium provided by the embodiments of the present application are described in detail with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 1, an embodiment of the present application provides a communication method, which is applied to a first terminal device, and the method includes:
the method provided by the embodiment of the application is applied to the first terminal device, wherein the first terminal device is a Bluetooth device, such as a Bluetooth headset, a bracelet and the like, or a mobile terminal with a Bluetooth function, such as a smart phone, a personal computer, a tablet computer or a wearable smart device and the like.
The second terminal device is a Bluetooth device or a mobile terminal with a Bluetooth function.
The first terminal equipment and the second terminal equipment start Bluetooth and directly carry out Bluetooth communication between the first terminal equipment and the second terminal equipment. I.e. the first signal is a bluetooth signal.
102, amplifying the first signal through a Wifi router through Wifi connection, and then sending a second signal to the second terminal device, where the second signal is demodulated by the second terminal device under the condition that it is determined that the signal strength of the second signal is greater than that 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 in a scene that the communication distance between the first terminal device and the second terminal device is large or an obstacle exists. Therefore, the Wifi router is used as a bluetooth relay between the first terminal device and the second terminal device.
Due to the fact that the Wifi network coverage is more and more popular, many public places such as subways, buses, squares and markets are covered by the Wifi network. Therefore, the Wifi router has a great practical value as a Bluetooth relay.
The first terminal device and the second terminal device have the same frequency as the Wifi router, for example, the first terminal device and the second terminal device all use a 2.4G network, so that the first terminal device and the second terminal device can communicate with the Wifi router.
The process of the first terminal device and the second terminal device communicating with the Wifi router is as follows:
1. the first terminal device sends a first signal P0 to the second terminal device and the Wifi router simultaneously;
2. after the first signal P0 is received by the Wifi router, the Wifi router amplifies the first signal P0, the amplified first signal P0 serves as a second signal P1, and the second signal P1 is sent to the second terminal device;
3. the second terminal equipment receives the first signal P0 and the second signal P1 in sequence, compares the signal strength of P0 with the signal strength of P1, and demodulates the signal with large signal strength. The signal strength is characterized by the level of the signal, and the greater the level, the greater the signal strength.
The propagation of the first signal P0 is affected by multipath effects, and the signal arriving at the second terminal device from the first terminal device is actually the result of the superposition of multiple signals.
As shown in fig. 2, the first signal P0 reaches 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 a 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 increased.
Fig. 3 shows a hardware block diagram of a Wifi router, which includes an antenna, a filter, a Wifi transceiver, a Wifi ap internal cache, and a PA (Power Amplifier).
The process of receiving the first signal P0 by the Wifi router includes: the first signal P0 is received by an antenna of the Wifi router, filtered by a filter and then input to a Wifi transceiver of the Wifi router. And the Wifi transceiver buffers the radio-frequency signals after down-converting the radio-frequency signals into baseband signals.
The transmission process of the first signal P0 by the Wifi router comprises the following steps: and the Wifi transceiver up-converts the baseband signals in the cache into radio frequency signals, amplifies the radio frequency signals by the PA, filters the radio frequency signals by the filter, and sends the radio frequency signals 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 frequency 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 additionally increased.
Although the second signal P1 is the first signal P0 amplified by 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 fig. 4, in a case where the distance between the Wifi router and the second terminal device B is much larger 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.
In the case that P1 is greater than P0, P1 is demodulated; in the case where P1 is smaller than P0, P0 is demodulated.
The embodiment of the application uses the wifi router as the Bluetooth relay, and the signal amplification function of the wifi router is used for amplifying the signal sent by the first terminal device, so that 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 the Bluetooth is enlarged under the condition that the Bluetooth power consumption is not changed, and extra professional equipment is not needed.
Optionally, before the first signal is amplified by the Wifi router through the Wifi connection and then sent to the second terminal device, the method further includes: displaying prompt information amplified by the Wifi router and used for forwarding signals 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;
when the first terminal device and the second terminal device establish Bluetooth connection, the first terminal device 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 device have the same frequency, so that the Wifi router and the first terminal device 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 display prompt information. The prompt message is used for prompting the user that the first signal can be amplified by the Wifi router. The display interface of the hint information 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 form of the first input may be a mouse click operation or a keyboard input operation, and the embodiment of the 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 hint information, a request for establishing a communication connection is sent to the Wifi router to establish a Wifi connection.
As shown in fig. 7, when a plurality of Wifi routers having the same frequency as the first terminal device exist within the preset range of the first terminal device, the related information of the Wifi routers is also displayed on the display interface of the prompt information.
The related information of the Wifi router includes the name and signal strength of the Wifi router, for example, the names of the Wifi routers are Wifi router 1 and Wifi router 2.
When the user clicks a 'yes' button on a display interface of the prompt message, the user needs to select the Wifi router. And sending a request for establishing communication connection to the Wifi router selected by the user according to the clicking and selecting operation 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 to establish Wifi connection. The control command is a Wifi signal.
The Wifi router listens for a signal sent by the first terminal device. 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 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 device exists in the preset range of the first terminal device, and a user can conveniently carry out Wifi connection operation according to the prompt information.
Optionally, the sending the request for establishing the communication connection to the Wifi router includes:
and sending a request for establishing communication connection to the Wifi router under the condition that the receiving power corresponding to the signal sent through the Bluetooth connection is smaller than a preset threshold value.
The signals transmitted through the bluetooth connection include signals transmitted by the first terminal device a and the second terminal device 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 a 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, the signal amplification function is started, and a 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 when the receiving power corresponding to the signal sent by the Bluetooth connection is small, so that the effective utilization of resources is realized.
Optionally, the method further comprises: and sending a transmission delay corresponding to data forwarding through the Wifi router to the second terminal device, wherein the transmission delay is used for indicating the second terminal device to receive the second signal after 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 the transmission delay t1 corresponding to the Wifi router for forwarding the first signal P0. The second terminal device does not receive the second signal until t 1. The second signal is received and then transmitted.
As shown in fig. 8, under the condition that neither the first terminal device a nor the second terminal device B passes through the Wifi router, a directly sends a signal to B, and B receives the signal at the same time. B then sends a signal directly to a, which receives the signal simultaneously. TX denotes transmission and RX denotes reception.
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 sends a signal to B through the Wifi router, resulting in a transmission delay t1, resulting in a delay t1 for B receiving and sending a signal, and a delay t1 for the received signal of a corresponding to the sent signal of B.
Then B sends a signal to A through a Wifi router, a 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 embodiment of the application, the transmission delay corresponding to the data forwarding through the Wifi router is sent to the second terminal device, the second terminal device is indicated to receive signals after the transmission delay, then the signals are sent, the first terminal device and the second terminal device are prevented from sending signals simultaneously, and the communication quality is improved.
Optionally, the method further comprises: determining the transmission delay based on the size of the data packet.
The transmission delay is determined according to the size of a data packet sent by the first terminal device to the second terminal device. The larger the packet is, the larger the transmission delay for data forwarding via the Wifi router is.
According to the embodiment of the application, the transmission delay is accurately determined, so that the second terminal equipment is indicated to receive signals after the transmission delay, the first terminal equipment and the second terminal equipment are better prevented from sending signals simultaneously, and the communication quality is improved.
As shown in fig. 10, the steps of the communication method according to the embodiment of the present application are as follows:
1. the first terminal device A and the 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 a first terminal device A exists in a preset range of the first terminal device A or not;
if the Bluetooth does not exist, the A and the B directly carry out Bluetooth communication without a Wifi router;
if the user does not connect with the Wifi router, prompting the user to connect with the Wifi router;
3. after the A is connected with the Wifi router, whether the receiving power corresponding to the signal sent by the A or the B is smaller than a preset threshold Pb or not is detected;
if not, the A and the B directly carry out Bluetooth communication without a Wifi router;
if yes, the A commands the Wifi router to start a Bluetooth signal amplification function, and the transmission delay t1 is agreed with the B;
4. the P0 sent by the A is amplified by the Wifi router to become a second signal P1, and the P1 is sent to the standby B through the Wifi router; while a sends P0 directly to B;
5. b judges whether P0 is smaller than P1, and demodulates the larger one.
