Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
Currently, most terminal devices support wireless local area network (WIFI) connection, wherein when the WIFI connection is performed, both communication parties can select corresponding frequency bands and channels for data transmission. The frequency bands of WIFI may include, but are not limited to, a 2.4G frequency band and a 5G frequency band, each frequency band corresponds to a plurality of channels, where there may be overlapping frequency ranges between the channels.
The operating modes of the WIFI connection may include a point-to-point (P2P) operating mode and a Station (STA) operating mode. The P2P operating mode is a wireless local area network direct connection mode (WIFI direct), and WIFI direct connection can be realized between different terminal devices to transmit data. For example, when the terminal device is connected to a television for wireless screen projection operation, the operating mode of the terminal device is the P2P operating mode. In the STA operation mode, the terminal device is connected as a Station (STA) to a wireless Access Point (AP), for example, the terminal device connects to a wireless router and accesses the internet through the wireless router to play a game.
In some scenarios, the terminal device performs data transmission in the P2P operating mode and the STA operating mode simultaneously, and the two operating modes are different channels in the 5G frequency band. For example, a mobile phone is wirelessly connected with a television for screen projection (in this connection, the mobile phone is in a P2P operating mode), and then the mobile phone is wirelessly connected with a router for network game (in this connection, the mobile phone is in an STA operating mode), at this time, the mobile phone needs to wirelessly project a screen with the television and needs to transmit data of the network game with the router.
However, the terminal device performs data transmission in the P2P operating mode and the STA operating mode at the same time, and since the two operating modes operate in channels with different frequency bands, frequent channel switching is required, so that the data transmission delay is high. For example, the mobile phone is wirelessly connected with the television for screen projection, and meanwhile, the mobile phone is wirelessly connected with the router for network game, so that the situations of jamming, high delay and the like may occur in the game process of the mobile phone, and the user experience is influenced. Further, in other scenes, the television may have a situation such as a screen splash, which affects the user experience.
The channel determining method is applied to terminal equipment, the terminal equipment can be a computer, a mobile phone, a tablet device, an intelligent wearable device and the like, and the method is not particularly limited to the terminal equipment as long as the terminal equipment has a WIFI function. The terminal device receives a starting instruction of a first P2P connection, acquires a first working channel of an established STA connection, and determines a second working channel of the first P2P connection according to the first working channel, wherein the frequency of the second working channel is completely overlapped with the frequency of the first working channel, namely the first P2P connection is the same as the working channel of the STA connection, so that the problem of frequently switching channels when both connections need to transmit data is solved, or the frequency band of the second working channel is different from that of the first working channel, so that both connections can simultaneously transmit data, and the first P2P connection is established based on the second working channel. When the terminal equipment is in the P2P working mode and the STA working mode at the same time, the data transmission delay is low, and the user experience is improved.
The following describes the technical solutions of the present disclosure and how to solve the above problems with specific examples.
Fig. 1 is a schematic flow chart of a method for determining a channel according to an embodiment of the present disclosure, as shown in fig. 1, the method of the present embodiment is executed by a terminal device, where the present disclosure is not limited, and the method of the present embodiment is as follows:
and S101, receiving a starting command of the first P2P connection.
Wherein, the starting instruction of the first P2P connection is used for indicating the starting of establishing the first P2P connection. The start instruction of the first P2P connection may be a start instruction of the first P2P connection received by the terminal device, and the start instruction of the first P2P connection may be various types of instructions. The starting instruction of the first P2P connection may be a touch instruction received by the electronic device at a specified position in a preset interface, for example, clicking a "first P2P connection" option in a WIFI setting interface starts the first P2P connection. The start instruction of the first P2P connection may also be a voice instruction, for example, the electronic device receives a voice message such as "connect P2P", "start to connect to tv" and the like through voice input, and starts the first P2P connection. The starting instruction of the first P2P connection may also be a preset clear gesture instruction, for example, if the electronic device receives a preset slide gesture, or if the user strokes a preset shape in the air, the first P2P connection is started. It is to be understood that the start command of the first P2P connection is not limited to the above form, and may be in other predefined forms. The received starting instruction of the first P2P connection may be in various forms, which is convenient for the user to select according to the actual needs, so as to start the first P2P connection.
For example, fig. 2 is a schematic diagram of a connection interface of a wireless screen projection device provided by the present disclosure, as shown in fig. 2, when a user clicks a "wireless screen projection" button on a terminal device to enter the connection interface of the wireless screen projection device, the terminal device automatically searches for surrounding devices that can be connected by wireless screen projection, and displays the devices in the connection interface of the wireless screen projection device, as exemplarily shown in fig. 2, 2 devices are respectively device 1 and device 2. The terminal device triggers and starts connection with the first P2P of the device by clicking the position corresponding to the device in the display interface, and if the user wants to connect the device 1 for wireless screen projection, the user can click the device 1 at the corresponding position in the interface, and the terminal device receives a starting instruction for performing the first P2P connection with the device 1, thereby triggering and starting the connection with the first P2P of the device 1.
S102, judging whether STA connection is established currently.
After receiving the start instruction of the first P2P connection, the terminal device needs to determine whether the STA connection is currently established, that is, the terminal device needs to determine whether a scenario in which the STA connection and the first P2P connection perform data transmission simultaneously occurs. If no STA connection is currently established, a first P2P connection is established according to the existing flow. If the STA connection is currently established, S103 is continuously performed.
S103, acquiring a first working channel of the established STA connection.
And S104, determining a second working channel connected with the first P2P according to the first working channel.
The frequency of the second working channel is completely overlapped with the frequency of the first working channel, or the frequency band of the second working channel is different from the frequency band of the first working channel.
In a possible implementation manner, it may be determined that, according to the first working channel of the established STA connection, the frequency of the second working channel of the first P2P connection completely overlaps with the frequency of the first working channel, that is, the working frequency band of the first P2P connection is the same as that of the STA connection, and the channels are the same.
Optionally, in a case that the frequency of the second operating channel completely overlaps with the frequency of the first operating channel, after the first P2P connection is established, the method of this embodiment may further include:
and controlling the first P2P connection and the STA connection to transmit data on the first working channel in a Time Division Multiplexing (TDM) manner.
In this embodiment, since the first P2P connection and the STA connection have the same channel, different signals may be transmitted in different time periods in a time division multiplexing manner, the time for transmitting data in the channel is divided into a plurality of time slices (referred to as time slots), and the time slots are allocated to the first P2P connection or the STA connection, so as to achieve the purpose of transmitting data in two operating modes (the first P2P connection and the STA connection), and further, the channel does not need to be frequently switched.
In another possible implementation manner, it may be determined that, according to the first operating channel of the established STA connection, a frequency band of the second operating channel of the first P2P connection is different from a frequency band of the first operating channel, that is, an operating frequency band of the first P2P connection is different from an operating frequency band of the STA connection.
Optionally, in a case that the operating frequency band of the first P2P connection is different from the operating frequency band of the STA connection, after the first P2P connection is established, the method of this embodiment may further include:
and controlling the first P2P connection and the STA connection to transmit data in an antenna multiplexing mode.
In this embodiment, the antenna multiplexing is to use the same antenna to perform data transmission in different frequency bands, and since the operating frequency bands of the P2P operating mode and the STA operating mode are different, an antenna multiplexing mode may be adopted, signals of the P2P operating mode and the STA operating mode may be transmitted in a parallel manner without interfering with each other, and transmission delay may not be considered when transmitting signals of any one of the two operating modes, so as to achieve the purpose of transmitting data in the two operating modes (the first P2P connection is connected with the STA), and the two operating modes do not interfere with each other, so that there is almost no transmission delay.
And S105, establishing a first P2P connection based on the second working channel.
In the process of establishing the first P2P connection, the two devices determine the working channel used by the first P2P connection through negotiation. In this embodiment, after the terminal device determines the second working channel, in the process of establishing the first P2P connection, the peer device connected with the first P2P negotiates to determine that the second working channel is used for the connection.
Further, in the process of establishing the first P2P connection, the two parties of the connection determine a master device (GO) and a slave device (GC) through negotiation, and the master device may set an operating channel used for the first P2P connection. In this embodiment, in the process of establishing the first P2P connection, the terminal device sets the P2P operation channel (P2P operation channel) as the second working channel, and sets a willingness value (GO intent) to become the master device at the same time, where the GO intent is 15 at maximum, and the larger the GO intent value is, the more willing to make the master device is indicated, so that the terminal device sets the GO intent to 15 (or 14), which indicates that the master device needs to be made, and after it is determined that the terminal device becomes the master device, the working channel connected by the first P2P is the second working channel.
In this embodiment, the terminal device obtains the first working channel of the established STA connection by receiving the start instruction of the first P2P connection, and determines the second working channel of the first P2P connection according to the first working channel, where the frequency of the second working channel completely overlaps with the frequency of the first working channel, that is, the first P2P connection is the same as the working channel of the STA connection, so as to avoid the problem of frequently switching channels when both connections need to transmit data, or the frequency band of the second working channel is different from the frequency band of the first working channel, so that both connections can simultaneously perform data transmission, thereby establishing the first P2P connection based on the second working channel. When the terminal equipment is in the P2P working mode and the STA working mode at the same time, the data transmission delay is low, and the user experience is improved.
On the basis of the foregoing embodiment, further, in the process of establishing the STA connection, the working channel of the STA connection is determined by the AP, and the terminal device cannot determine the working channel of the STA connection, so that if the terminal device has already established the first P2P connection, and the terminal device needs to establish the STA connection at this time, it may determine whether to disconnect the first P2P connection first according to the channels of the STA connection and the already established first P2P connection, and then establish the first P2P connection by using the foregoing method.
Fig. 3 is a schematic flow diagram of another channel determination method provided in the embodiment of the present disclosure, where fig. 3 is based on the embodiment shown in fig. 1, and further, as shown in fig. 3, the method of this embodiment may further include S1001, S1002, and S1003:
s1001, receiving a starting instruction of STA connection and establishing the STA connection.
The starting instruction of the STA connection is used for indicating the starting of establishing the STA connection. The STA connection start instruction may be a STA connection start instruction received by the terminal device, and the STA connection start instruction may be an instruction in various forms. The STA connection starting instruction may be a touch instruction received by the electronic device at a specified position in a preset interface, for example, the "STA connection" option is clicked in a WIFI interface to start the STA connection. The STA connection starting instruction may also be a voice instruction, for example, the electronic device receives a voice message such as "connect STA", "start to connect WIFI" input by voice, and starts the STA connection. The start instruction of the STA connection may also be a preset idle gesture instruction, for example, when the electronic device receives a preset sliding gesture, or the user strokes a preset shape in the air, the STA connection is started. It is to be understood that the STA connection start instruction is not limited to the above-described form, and may be in another predefined form, and the STA connection start instruction is different from the first P2P connection start instruction. The received starting instruction of the STA connection can be in various forms, and a user can conveniently select the starting instruction according to actual needs, so that the STA connection is started.
In this embodiment, the STA connection is established according to the received start instruction of the STA connection, and then the working channel of the STA connection may be determined.
S1002, judging whether a second P2P connection is established currently.
After the STA connection is established, the terminal device needs to determine whether a second P2P connection is established currently, that is, the terminal device needs to determine whether a scenario that the STA connection and the second P2P connection perform data transmission simultaneously occurs.
If the second P2P connection is not established, data transmission of the STA connection is performed according to the existing procedure, and further, after the STA connection is established, if a start instruction of the first P2P connection is received, the first P2P connection may be established according to the method shown in fig. 1.
If the second P2P connection has been established, execution continues with S1003.
S1003, judging whether the STA connection and the established second P2P connection are in different channels of the same frequency band.
If the STA connection and the established second P2P connection are not in different channels of the same frequency band, that is, the STA connection and the established second P2P connection are in the same channel, or the STA connection and the established second P2P connection are in different frequency bands, the data transmission of the STA connection and the data transmission of the second P2P connection are performed according to the existing procedure.
If the STA connects to a different channel in the same frequency band as the established second P2P connection, S1004 is executed continuously.
And S1004, disconnecting the established second P2P connection.
If the STA connection and the established second P2P connection are in different channels of the same frequency band, the STA connection and the established second P2P connection may cause a high data transmission delay when transmitting data simultaneously, so that the established second P2P connection may be disconnected.
Further, after the established second P2P connection is disconnected, the first P2P connection may be automatically reestablished, or the first P2P connection may be established after receiving a start command of the first P2P connection.
In this embodiment, after receiving an STA connection start instruction and establishing an STA connection, determining that the STA connection and the established second P2P connection are in different channels of the same frequency band, at this time, when the STA connection and the established second P2P connection transmit data simultaneously, data transmission delay is high, the established second P2P connection may be disconnected, and then, according to the established first working channel of the STA connection, the first P2P connection may be re-established, and the second working channel of the first P2P connection is determined, so that when the terminal device is in the P2P working mode and the STA working mode simultaneously, data transmission delay is low, and user experience is improved.
Fig. 4 is a schematic flowchart of a method for determining a channel according to another embodiment of the present disclosure, where fig. 4 is based on the embodiment shown in fig. 1 or fig. 3, and further, as shown in fig. 4, the method of this embodiment may further include S106:
and S106, suspending part of the service operated by the STA connection.
Wherein, part of the services include: scanning for wireless local area network access point traffic, and/or wireless roaming traffic.
In the STA operating mode, part of the service of WIFI may be run, for example, scan wlan access point service, and/or wireless roaming service. The operation of part of services will affect the data transmission of the STA connection, and therefore, the operation of part of services of the STA connection can be reduced or suspended.
In this embodiment, by suspending part of the service in which the STA is connected to operate, the data transmission in which the STA is connected to is less delayed by the operation of the part of the service, so that when the terminal device is in the P2P operating mode and the STA operating mode at the same time, the data transmission delay is low, and the user experience is improved.
On the basis of the above embodiment, further, after S105, the method may further include: the resolution of the data transmitted in the first P2P connection is adjusted to a preset resolution interval, and/or the frame rate is adjusted to a preset frame rate interval.
For example, when the first P2P connection is used for wireless screen projection, if the resolution of the current image quality is 4K, the frame rate is 60 frames, and the current image quality is ultra high definition, the resolution and/or the frame rate of the data transmitted in the first P2P connection can be reduced to a corresponding section, and the data transmitted in the first P2P connection can be reduced without affecting the image quality.
In this embodiment, the resolution of the data transmitted in the first P2P connection is adjusted to a preset resolution interval, and/or the frame rate is adjusted to a preset frame rate interval. The amount of data transmitted in the first P2P connection can be made small, so as to further solve the problem of high data transmission delay, so that the data transmission delay in the first P2P connection is low, and the user experience is improved.
Fig. 5 is a schematic structural diagram of a channel determination apparatus provided in an embodiment of the present disclosure, and as shown in fig. 5, the apparatus of this embodiment may include:
a receiving module 501, configured to receive a start instruction of a peer-to-peer first P2P connection, and acquire a first working channel to which an established STA is connected;
