Technical Field

The present application relates to the field of terminal technologies, and in particular, to a data transmission method, an electronic device, and a storage medium

Background

With the development of technology in recent years, most electronic devices support Peer-TO-Peer (P2P) data transmission. However, when data is transmitted between devices through the P2P link, the P2P link is easily affected by a wireless network around the devices, and channel interference occurs, thereby increasing data transmission delay. The applicant found through testing that in the process of using the P2P transmission link to transmit data, if co-channel interference occurs (when the duty cycle is 75%), the network delay increases to 100ms. Under the different channel interference (when the duty ratio is 75%), the network delay is greatly fluctuated, and the maximum time delay can reach 1100ms.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. Wherein, in the description of the embodiments of the present application, unless otherwise indicated, "/" means or, for example, a/B may represent a or B; "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone.

The terms "first" and "second" are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the embodiments of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

As described above, when data is transmitted between devices through the P2P link, the P2P link is easily affected by WiFi networks around the devices, and channel interference occurs, thereby increasing data transmission delay.

Various methods have been proposed in the prior art to reduce the effects of channel interference. For example, in a screen-drop scenario, during a data transmission process of a source device and a target device through a P2P link, if the P2P link is interfered by one or more wireless networks around the source device or the target device, the source device may generally ensure a delay and a frame rate by reducing sharpness (i.e., a code rate). It is apparent that reducing sharpness necessarily reduces the user experience.

In order to solve the above technical problems, in the process of transmitting data by the first electronic device and the second electronic device through the P2P link, if the P2P link is detected to be affected, the first electronic device and the second electronic device may be connected to the same Access Point (AP), and the frequency band supported by the Access point is different from the frequency band supported by the P2P link. In this way, the first electronic device may transmit data to the second electronic device over the P2P link while forwarding data to the second electronic device over the connected access point. That is, the following is true. The first electronic device may send data to be transmitted to the second electronic device over both paths simultaneously. Through testing, the applicant finds that compared with the prior art, the average time delay can be reduced by 28%, and the frame rate can be improved by 10fps.

The method of data transmission provided by the application is explained and illustrated below with reference to the drawings in the specification. Fig. 1A-1B are schematic communication diagrams of a first electronic device and a second electronic device according to an embodiment of the present application.

The first electronic device and the second electronic device may include smart terminals such as a mobile phone, a tablet computer, and a wearable device.

Referring to fig. 1A, a first electronic device 102 accesses a first access point AP1106. Specifically, the first electronic device 102 and the first access point AP1106 may be connected via the second link 110. The second link may be a link in a second frequency band, that is, the first access point AP1106 may support the second frequency band.

Specifically, the first access point AP1106 may include a wireless router, a wireless gateway, a wireless bridge, or the like. Taking the first access point AP1106 as an example of a wireless router, the first access point AP1106 may implement access and forwarding of data of the first electronic device 102. In general, the wireless router may include a single frequency router, a dual frequency router, or a tri-frequency router. Wherein the single frequency router supports a communication band, such as 2.4g. The dual-band router supports two communication bands, such as 2.4g and 5g low frequencies. The three-frequency router supports three communication frequency bands of 2.4g,5g of low frequency and 5g of high frequency, and the corresponding communication frequencies are 2.4GHz,5GHz and 5.8GHz. It will be appreciated that, as communication technologies evolve, the communication frequency band supported by the wireless router may vary accordingly, and embodiments of the present application are not limited in this respect.

Illustratively, the second frequency band in the present application may include a 2.4G frequency band or a 5G frequency band. It is understood that the frequency range of the 2.4G band may be: 2400-2488 MHz. The frequency range of the 5G band may be: 4910-5835 MHz.

With continued reference to fig. 1A, a first link 108 may be established between the first electronic device 102 and the second electronic device 104, which may be a link 108 in a first frequency band. The first frequency band may include a 2.4G frequency band or a 5G frequency band. In one example, the first link 108 is a P2P link.

The first link 108 may be established in a variety of ways. In one example of the application, the first electronic device 102 and the second electronic device 104 may establish the first link 108 based on a WiFi P2P or the like protocol. It will be appreciated that the WiFi P2P protocol is still capable of implementing a point-to-point WiFi connection between devices such as smartphones and televisions in environments where there is no conventional WiFi network or WiFi access point. That is, in this example, the establishment of the first link 108 is not based on the first electronic device 102 and the second electronic device 104 being connected to an access point. It is to be appreciated that the first link 108 supporting the first frequency band may also be established based on other P2P protocols, which is not limiting to the present application.

Further, the first link 108 may be used to transmit a variety of data. For example, the first link 108 may be used to transmit the screen-casting data during the screen-casting of the first electronic device 100 and the second electronic device 104. However, as shown above, in the near field communication application scenario such as screen projection, the communication frequency band used by other wireless local area networks or cellular networks is the same as or adjacent to the first frequency band, and interference is easily generated to the first link 108, such as co-channel interference or off-channel interference, which results in an increase in data transmission delay.

In one embodiment of the application, the first electronic device 102 may acquire and compare the first frequency band and the second frequency band. If the first frequency band and the second frequency band are different, the first electronic device 102 may send a connection indication to the second electronic device 104 to instruct the second electronic device 104 to access the first access point AP1106.

Specifically, the first electronic device 102 may acquire, based on the network card related information thereof, a first frequency band supported by the first link 108 (i.e., a frequency band supported by the first access point) and a second frequency band supported by the second link 110.

Further, after the second electronic device 104 receives the connection instruction, the second electronic device 104 may access the first access point AP1106 based on the feature information of the first access point AP1106.

Note that the characteristic information of the AP1106 of the first access point may include a service set identifier (Service Set Identifier, SSID) and a physical (Media Access Control, MAC) address of the AP1106, and the like.

In one example of the present application, the first electronic device 102 may send the SSID, MAC, etc. of the first access point AP1106 to the second electronic device 104 at regular time, so that the second electronic device 104 accesses the first access point based on the characteristic information of the first access point after receiving the connection indication.

In an example of the present application, the connection instruction may include information such as an SSID or an MAC of the AP1106 of the first access point, so that the second electronic device 104 accesses the first access point based on the characteristic information of the first access point after receiving the connection instruction.

In another embodiment of the present application, the first electronic device 102 may measure the quality of service (Quality of Service, QOS) of the first link 108, and if the QOS of the first link 108 meets the preset condition, the first electronic device 102 may acquire and compare the first frequency band and the second frequency band. If the first frequency band is different from the second frequency band, the first electronic device 102 sends a connection indication to the second electronic device 104. In this embodiment, QOS of the first link may include packet loss rate, transmission bandwidth, transmission delay, and the like. Further, when one or more of the packet loss rate, the transmission bandwidth, the transmission delay, and the like is greater than a preset threshold, it is determined that QOS of the first link satisfies the preset condition. It can be understood that, in the present application, the QOS of the first link satisfying the preset condition indicates that the QOS of the first link is poor, and that channel interference is likely to occur.

Referring to fig. 1B, after the second electronic device 104 accesses the first access point AP1106, the first access point AP1106 and the second electronic device 104 may be connected through a third link 112, and the third link 112 may be a link in the second frequency band.

In another embodiment of the present application, if the first frequency band is different from the second frequency band, the first electronic device 102 may directly send the characteristic information of the first access point AP1106 to the second electronic device 104, and the second electronic device 104 decides whether to access the first access point. Specifically, after receiving the feature information of the first access point AP1106, the second electronic device 104 may measure the signal strength of the first access point AP1106, and if the signal strength meets the preset requirement, the second electronic device 104 may access the first access point AP1106.

Further, the characteristic information may further include a connection key of the first access point AP1106, so as to facilitate the second electronic device 104 accessing the first access point AP1106.

After the first electronic device and the second electronic device access the same access point, the first electronic device 102 may redundantly transmit data to the second electronic device 104 via two paths. That is, the first electronic device 102 may send the first data to the second electronic device 104 over the first link 108, the first electronic device 102 forwards the second data to the second electronic device 104 over an access point that is simultaneously accessed by the second electronic device, and the first data and the second data are the same. That is, the same frame of data is transmitted simultaneously on two paths. Therefore, the second electronic equipment performs sequencing and de-duplication processing on the received data, so that the data transmission efficiency can be greatly improved, and the time delay is reduced.

In the present application, there are a plurality of networking modes for the first electronic device 102, the second electronic device 104, and the first access point AP 1. The networking mode in the embodiment of the present application is described below with reference to fig. 2A-2B.

Referring to fig. 2A, the first electronic device 102 is connected to the second electronic device 104 through the first link 108, the first electronic device 102 accesses the first access point AP1106, and the first electronic device 102 is connected to the first access point AP1106 through the second link 110.

Referring to fig. 2A, the first frequency band may be a 2.4G frequency band, and the second frequency band is a 5G frequency band, that is, the first access point AP1 may support the 5G frequency band.

Referring to fig. 2B, after the second electronic device 104 accesses the first access point 106, the second electronic device 104 is connected to the first access point AP1106 through a third link 112, where the third link 112 is a link in the second frequency band.

Referring to fig. 3A-3B, an exemplary diagram of networking according to one embodiment of the present application is shown.

Referring to fig. 3A, the first electronic device 102 is connected to the second electronic device 104 through the first link 108, the first electronic device 102 accesses the first access point AP1106, and the first electronic device 102 is connected to the first access point AP1106 through the second link 110.

Referring to fig. 3A, the first frequency band may be a 5G frequency band, and the second frequency band is a 2.4G frequency band, that is, the first access point AP1 may support the 2.4G frequency band.

Referring to fig. 3B, after the second electronic device 104 accesses the first access point AP1106, the second electronic device 104 is connected to the first access point AP1106 through a third link 112, where the third link 112 is a link in the second frequency band.

It can be seen that, in the networking shown in fig. 3A and fig. 3B, two data transmission paths exist between the first electronic device and the second electronic device, and compared with the single-path P2P transmission in the prior art, the data transmission efficiency can be further improved.

The interaction flow between the first electronic device and the second electronic device in one embodiment of the present application is explained and illustrated with reference to fig. 4.

In step 502, a first electronic device accesses a first access point.

In step 504, a first link in a first frequency band is established between the first electronic device and the second electronic device.

In step 506, the first electronic device sends the characteristic information of the first access point to the second electronic device, where the characteristic information may include information such as SSID, MAC, etc. of the first access point.

Step 508, the first electronic device detects the service quality of the first link, if the service quality is poor, further determines whether the first frequency band is consistent with the second frequency band, and if not, sends a first indication to the second electronic device. In particular, the first indication may be used to instruct the second electronic device to access the first access point.

Specifically, whether the quality of service of the first link satisfies the preset condition may be determined based on QOS related information. If the packet loss rate is greater than the preset threshold, it may be determined that the service quality of the first link is poor, and the above-mentioned two-way transmission is required.

Step 510, the second electronic device accesses the first access point, and establishes a third link in the second frequency band with the first access point.

In one example of the present application, after receiving the first indication, the second electronic device may measure whether the signal strength of the first access point is greater than a preset threshold, and if so, access the first access point. Specifically, the second electronic device may measure a signal strength value of the first access point based on the received characteristic information of the first access point. The signal strength value is used to characterize the channel quality and may be a received channel strength indication (received signal strength indication, RSSI). For example, the RSSI measured by the second electronic device.

In another example of the present application, after the second electronic device accesses the first access point, a message confirming access to the first access point may be sent to the first electronic device.

In step 512, the first electronic device sends the first data to the second electronic device through the first link, and the first electronic device forwards the second data to the second electronic device through the first access point, where the first data and the second data are the same data.

It should be noted that, the interaction flow in the first electronic device and the second electronic device in fig. 4 is only exemplary, and is not limited to the interaction flow shown in fig. 4. For example, the steps of steps 502 and 504 may be interchanged. For another example, steps 506 and 508 are combined, that is, the first electronic device detects the service quality of the first link, determines, based on the detection result, whether the first frequency band is consistent with the second frequency band, and if not, sends a first indication to the second electronic device, where the first indication further includes the characteristic information of the first access point.

In summary, the first electronic device and the second electronic device perform redundant transmission on data through two paths, so that data transmission efficiency is improved.

Referring now to fig. 5A-5B, a schematic diagram of communication between a first electronic device 102 and a second electronic device 104 is provided in another embodiment of the present application.

Referring to fig. 5A, the first electronic device 102 accesses the first access point AP1106, the first electronic device 102 may forward or receive data through the first access point AP1106, and in particular, the first electronic device 102 and the first access point AP1106 may be connected through the second link 110. The second link may be a link in a second frequency band, that is, the first access point AP1106 may support the second frequency band.

Further, the second electronic device 104 accesses to the second access point AP2114, and the second electronic device 104 may forward or receive data through the second access point AP2114, where the second electronic device 104 may transmit data with the second access point AP2114 through the fourth link 116 under the third frequency band, that is, the second access point AP2114 may support the third frequency band. The third frequency band in the present application may include a 2.4G frequency band or a 5G frequency band, etc.

With continued reference to fig. 5A, the first electronic device 102 and the second electronic device 104 are connected by a first link 108 in a first frequency band, the first link 108 comprising a P2P link.

In one embodiment of the application, the first electronic device 102 and the second electronic device 104 may exchange characteristic information of the connected access points. For example, the first electronic device 102 may send the characteristic information of the first access point AP1 to the second electronic device 104 at each interval for a preset period of time. The second electronic device 104 may also send the characteristic information of the second access point AP2114 to the first electronic device 102 at each interval for a preset period of time. The characteristic information may include SSID, MAC, operating band, etc. of the access point.

In one embodiment of the present application, the first electronic device 102 may measure the QOS of the P2P link, when detecting that the QOS of the P2P link meets the preset condition, the first electronic device 102 may compare the characteristic information of the first AP1106 and the second AP2112, and if the characteristic information (such as SSID and MAC) of the first AP1106 and the second AP1114 are inconsistent, it may be determined that the first AP1106 and the second AP1114 are not identical access points. That is, the first electronic device determines whether to perform the two-way transmission by measuring QOS of the first link of the link.

Further, after determining that the first access point and the second access point are not the same access point, the first electronic device 102 may acquire the first frequency band and the second frequency band, and acquire the third frequency band from the second electronic device 104, and compare the first frequency band with the second frequency band and the third frequency band, respectively.

In one embodiment, if the first frequency band is different from the second frequency band, the first electronic device 102 may send a connection indication to the second electronic device 104, where the connection indication is used to instruct the second electronic device 104 to disconnect from the second access point AP2114 and access the first access point AP1106, so that the second electronic device 104 is connected to the first access point AP1106 through the third link 112. In this way, the first electronic device may forward data to the second electronic device 104 through the first access point AP1106. In one example of the present application, the second electronic device 104 may disconnect directly from the second access point and access the first access point after receiving the connection indication. In another example of the present application, after receiving the connection instruction, the second electronic device 104 may measure the signal strength of the first access point AP1106, and based on the signal strength measurement result, decide whether to disconnect from the second access point AP2114 and access the first access point AP1106.

In another embodiment of the present application, if the first frequency band is different from the third frequency band, the first electronic device 102 may disconnect from the first access point AP1106 and directly access the second access point AP1106, so that the first electronic device 102 may forward data to the second electronic device directly through the second access point AP 2114.

In another example of the present application, if the first frequency band is different from the second frequency band and the third frequency band, the first electronic device 102 may measure and obtain the first signal strength of the first access point AP1106 and the second signal strength of the second access point AP2114, and obtain the third signal strength of the second electronic device 102 under the second access point AP2114 and the fourth signal strength of the second electronic device 104 under the second access point AP2114 from the second electronic device 104, respectively. The first electronic device 102 compares the first signal strength with the third signal strength and the second signal strength with the fourth signal strength, and based on the comparison result, determines whether to access the second access point AP2114 or send a connection indication to the second electronic device 104. For example, if the first signal strength is greater than the third signal strength and the second signal strength is greater than the fourth signal strength, the first electronic device 102 may send a connection indication to the second electronic device 104. If the first signal strength is less than the third signal strength and the second signal strength is less than the fourth signal strength, the first electronic device 102 may switch from the first access point to the second access point.

It can be seen that there are two paths between the first electronic device and the second electronic device for data interaction. I.e. the first electronic device may send data to the second electronic device via the first link, or may forward data to the second electronic device 104 via the first access point AP 1106.

In another embodiment of the present application, before the second electronic device 104 disconnects from the second access point AP2114, the wifi outbound interface route thereof may be changed to the first link 108 (P2P link), and the wifi IP/listening port may be sent to the first electronic device 102 to proxy surfing through the first electronic device 102. In this way, when the second electronic device is in the core network for data interaction, the second access point AP2114 is disconnected, so that the second electronic device is prevented from being disconnected, and the user experience is prevented from being affected.

In the present application, since the first frequency band, the second frequency band, and the third frequency band may all include multiple frequency bands, in the present application, there are multiple networking modes for the first electronic device 102, the second electronic device 104, and the first access point AP1 and the second access point AP 2.

Referring to fig. 7A, the first electronic device 102 is connected to the second electronic device 104 through the first link 108, the first electronic device 102 accesses the first access point AP1106, and the first electronic device 102 is connected to the first access point AP1106 through the second link 110. The second electronic device 104 accesses the second access point AP2114, and the second electronic device 104 is connected to the second access point AP2114 through the fourth link 116.

The first frequency band supported by the first link 108 is a 5G frequency band, the second frequency band supported by the second link 110 is a 2.4G frequency band, and the third frequency band supported by the fourth link 116 is a 2.4G frequency band.

Referring to fig. 7B, after the second electronic device 104 accesses the first access point 106, the second electronic device 104 is connected to the first access point AP1106 through a third link 112, where the third link 112 is a link supporting the second frequency band.

In this example, the first electronic device 102 and the second electronic device 104 may access the second access point AP2114 simultaneously.

Referring to fig. 8A, the first electronic device 102 is connected to the second electronic device 104 through the first link 108, the first electronic device 102 accesses the first access point AP1106, and the first electronic device 102 is connected to the first access point AP1106 through the second link 110. The second electronic device 104 accesses the second access point AP2114, and the second electronic device 104 is connected to the second access point AP2114 through the fourth link 116.

The first frequency band supported by the first link 108 is a 2.4G frequency band, the second frequency band supported by the second link 110 is a 5G frequency band, and the third frequency band supported by the fourth link 116 is a 5G frequency band.

Referring to fig. 8B, after the second electronic device 104 accesses the first access point 106, the second electronic device 104 is connected to the first access point AP1106 through a third link 112, where the third link 112 is a link supporting the second frequency band.

Referring to fig. 9A, the first electronic device 102 is connected to the second electronic device 104 through the first link 108, the first electronic device 102 accesses the first access point AP1106, and the first electronic device 102 is connected to the first access point AP1106 through the second link 110. The second electronic device 104 accesses the second access point AP2114, and the second electronic device 104 is connected to the second access point AP2114 through the fourth link 116.

The first frequency band supported by the first link 108 is a 2.4G frequency band, the second frequency band supported by the second link 110 is a 5G frequency band, and the third frequency band supported by the fourth link 116 is a 2.4G frequency band.

Referring to fig. 9B, after the second electronic device 104 accesses the first access point 106, the second electronic device 104 is connected to the first access point AP1106 through a third link 112, where the third link 112 is a link supporting the second frequency band.

It can be seen that, in the networking shown in fig. 6A-6B, fig. 7A-7B, fig. 8A-8B, and fig. 9A-9B, two data transmission paths exist between the first electronic device and the second electronic device, and compared with the single-path P2P transmission in the prior art, the data transmission efficiency can be further improved.

The interaction flow between the first electronic device and the second electronic device in one embodiment of the present application is explained and illustrated with reference to fig. 10.

In step 1100, a first link in a first frequency band is established between a first electronic device and a second electronic device.

In step 1102, the first electronic device accesses to a first access point, where the first electronic device is connected to the first access point through a second link in a second frequency band, and the first access point can support the second frequency band.

In step 1104, the second electronic device accesses the second access point, where the second access point may support the third frequency band, and the second electronic device is connected to the second access point through a fourth link in the third frequency band.

In step 1106, the first electronic device sends the characteristic information of the first access point to the second electronic device, where the characteristic information may include information such as SSID, MAC, etc. of the first access point.

In step 1108, the second electronic device sends the characteristic information of the second access point to the second electronic device, where the characteristic information may include information such as SSID, MAC, etc. of the second access point.

At step 1110, the first electronic device detects QOS for the first link. Specifically, QOS may specifically include a packet loss rate, a transmission delay, a transmission bandwidth, and the like in a data transmission process of the first link.

In step 1112, the first electronic device 102 determines whether the characteristic information of the first access point and the characteristic information of the second access point are consistent based on the measurement result.

The step is used for judging whether the first access point and the second access point belong to the same access point. It is appreciated that based on the SSID, MAC, etc. information of the first access point AP1106 and the second access point, it may be determined whether the first access point and the second access point belong to the same access point.

In an example of the present application, the SSID, MAC, etc. information of the first access point and the second access point are consistent, that is, the first access point and the second access point belong to the same access point, the first electronic device may send the first data to the second electronic device through the first link, and the first electronic device forwards the first data to the second electronic device through the first access point (step 1122), thereby improving the data transmission efficiency.

In step 1114, the first electronic device determines whether the first frequency band is the same as the second frequency band and/or the third frequency band.

In one embodiment of the present application, if the first access point and the second access point do not belong to the same access point, the first electronic device determines whether the first frequency band supported by the first link is the same as the second frequency band supported by the second link and/or the third frequency band supported by the fourth link.

In one example of the present application, if the first frequency band and the third frequency band are different, the first electronic device may be disconnected directly from the first access point, connected to the second access point, and forward data to the second electronic device through the second access point (step 1124). Further, if the first frequency band is different from the third frequency band, the first electronic device may further measure the signal strength of the second access point, and if the signal strength of the second access point is greater than a preset threshold, the first electronic device may disconnect from the first access point and access to the second access point. The first electronic device may send the first data to the second electronic device through the first link, and the first electronic device forwards the first data to the second electronic device through the second access point (step 1126), thereby improving data transmission efficiency.

In step 1116, if the first frequency band is different from the second frequency band, the first electronic device sends a connection indication to the second electronic device.

In one example of the present application, if the first frequency band and the second frequency band are different, the first electronic device sends a connection instruction to the second electronic device, and the second electronic device may disconnect from the second access point directly after receiving the connection instruction, and then access the first access point (step 1116), so that the first electronic device forwards the first data to the second electronic device through the first access point.

In another example of the present application, if the first frequency band is different from the second frequency band, the first electronic device sends a connection instruction to the second electronic device, the second electronic device may measure the signal strength of the first access point after receiving the connection instruction, and if the signal strength of the first access point is greater than a preset threshold, the second electronic device disconnects from the second access point and then accesses the first access point, so that the first electronic device forwards the first data to the second electronic device through the first access point. Further, before the second electronic device disconnects from the second access point, the wifi output interface route of the second electronic device may be changed to the first link 108 (P2P link), and the wifi IP/listening port may be sent to the first electronic device 102, so as to proxy surfing through the first electronic device 102. In this way, when the second electronic device is in the core network for data interaction, the second access point AP2114 is disconnected, so that the second electronic device is prevented from being disconnected, and the user experience is prevented from being affected. The applicant finds through tests that the average time delay can be reduced by 28% compared with the prior art by adopting the scheme of the application, and the frame rate is improved by 10fps.
