Currently, in order to achieve higher data transmission efficiency, many terminal devices are integrated with dual-receiving and dual-transmitting WIFI modules, that is, the WIFI modules support real-time operation of 2.4G frequency bands and 5G frequency bands, rather than a time division multiplexing operation mode. When the terminal equipment integrates the module, the ideal state is that the screen-throwing connection interface of the terminal equipment and the screen-throwing end equipment and the interface connected with an external network work on different frequency bands when the screen throwing is performed, so that signal interference is reduced. However, in the actual channel negotiation process, the working channel negotiated by the terminal device screen-switching connection interface may interfere with the working channel of the interface connected to the external network. At this time, since the terminal device automatically saves the time of repeating the network negotiation, the channel negotiation result of the screen-on connection with the current device is automatically saved. Therefore, when the same equipment is screen-switched again, the stored channels with mutual interference are continuously used for data transmission, namely the problem that the same equipment always performs data transmission on the channels with lower efficiency in the screen-switched process exists.
In order to solve the above problems, the present invention provides a method for optimizing a screen-projection channel, comprising: obtaining a negotiation result of networking negotiation with a screen throwing end; judging whether a working channel of a first connection interface between the screen throwing end and the first connection interface is an optimal channel according to the negotiation result; if the working channel of the first connection interface is the optimal channel, the negotiation result is saved; and transmitting the screen projection data by using the optimal channel according to the negotiation result. According to the method, before the networking negotiation result is stored, whether the working channel is an optimal channel or not, namely whether the working channel is a channel with higher transmission efficiency is judged, and the negotiation result is stored only when the working channel is the optimal channel, so that the same equipment always uses the optimal channel for data transmission in the subsequent screen throwing process. The problem that the same equipment always performs data transmission on a channel with lower efficiency in the screen throwing process is solved, and the technical effect of improving the data transmission efficiency is achieved.
The embodiment of the invention provides a screen-projection channel optimization method, and referring to fig. 2, fig. 2 is a flow chart of an embodiment of the screen-projection channel optimization method of the invention.
In this embodiment, the method for optimizing the screen-projection channel includes:
step S10, obtaining a negotiation result of networking negotiation with the screen throwing end.
In this embodiment, the executing body is a screen-thrown end in the screen-throwing process, for example, when the mobile phone end performs mirror image screen-throwing on the television end through the Miracast technology, the screen-thrown end at this time is the television end, that is, the executing body is a television, and in addition, the screen-thrown end may also be called a receiving end. The networking negotiation refers to a negotiation process of network construction between the screen-throwing end and the screen-throwing end when the screen-throwing is performed, and the negotiation result mainly refers to a working channel of a screen-throwing connection interface selected after the screen-throwing end and the screen-throwing end complete the negotiation, wherein the screen-throwing connection interface is an interface for transmitting audio and video data to be played in the screen-throwing process.
Specifically, for example, as shown in fig. 3, after the networking negotiation is completed, a negotiation channel ChanP p0 (i.e. a working channel of a first connection interface to be described later) is recorded, and according to the recorded negotiation channel ChanP p0, a negotiation result of the networking negotiation with the screen-throwing end is obtained for further performing other steps in fig. 3.
And step S20, judging whether the working channel of the first connection interface between the screen throwing end and the first connection interface is an optimal channel according to the negotiation result.
In this embodiment, the first connection interface refers to a screen-throwing connection interface for performing data transmission between a screen-throwing end and a screen-thrown end, and the optimal channel is a working channel with higher data transmission efficiency and no interference with other network connection interfaces of the screen-throwing end.
It should be noted that, at this time, the screen-thrown end needs to be configured with a WIFI module for implementing dual receiving and dual transmitting, and in this case, the screen-thrown end will only have the mutual interference of the two interface working channels, so it is only necessary to determine whether the working channel of the first connection interface is an optimal channel.
Specifically, for example, working channel information of a first connection interface between the first connection interface and the screen throwing end in the negotiation result is obtained, wherein the working channel information comprises frequency bands and specific channel information; to determine whether the working channel of the first connection interface is an optimal channel.
Optionally, step S20 further includes, after determining whether the working channel of the first connection interface between the first connection interface and the screen-throwing end is an optimal channel according to the negotiation result:
step S50, if the working channel of the first connection interface is not the optimal channel, the negotiation result is abandoned to be saved.
In this embodiment, the working channel of the first connection interface is not the optimal channel, that is, the working channel of the screen-throwing interface negotiated by the screen-throwing end and the screen-throwing end at this time, and the working channels of other network connection interfaces of the screen-throwing end will interfere with each other, resulting in lower transmission efficiency. For example, the working channels of the two interfaces are in different channels of the same frequency band, so that the WIFI module at the screen-thrown end needs to frequency-hopping between different channels of the same frequency band at the moment, thereby affecting the working performance of the two interfaces at the same time. Therefore, the function of automatically storing the negotiation result by the screen throwing end is limited at the moment, and the current negotiation result is not stored.
According to the method, when judging that the working channel of the first connection interface for screen-throwing data transmission is not the optimal channel in the negotiation result, the current negotiation result is not saved, so that networking negotiation is conducted again when the same equipment is screen-throwing again, the working channel is reselected, and the transmission of screen-throwing data is not carried out by continuously using the channel with lower transmission efficiency negotiated in the previous screen-throwing process.
Step S30, if the working channel of the first connection interface is the optimal channel, the negotiation result is saved;
In this embodiment, when the working channel of the first connection interface is the optimal channel, the negotiation result, that is, the current working channel of the first connection interface is saved.
Specifically, for example, if the working channel of the first connection interface is an optimal channel, acquiring equipment identification information of the screen throwing end; and storing the negotiation result through a wpa (Wi-Fi Protected Access, wi-Fi network security access) module according to the equipment identification information of the screen throwing end. When the screen-throwing connection is carried out with the same equipment again, the stored working channel can be directly used for carrying out data transmission according to the equipment identification information, so that on one hand, the time for carrying out networking negotiation again is saved, and on the other hand, the used working channel is an optimal channel, and therefore the technical effect of improving the screen-throwing data transmission efficiency is achieved.
And step S40, transmitting screen projection data by using the optimal channel according to the negotiation result.
In this embodiment, the optimal channel is the working channel of the first connection interface stored in the foregoing step. Because the negotiation result is stored, when the screen-throwing end is connected with the corresponding screen-throwing end, the screen-throwing data is transmitted directly according to the working channel, namely the optimal channel, in the stored negotiation result.
Specifically, for example, when the screen projection data is transmitted, the working channel information in the stored negotiation result is acquired, and according to the working channel information, a corresponding working channel is selected to transmit the screen projection data.
The embodiment obtains a negotiation result of networking negotiation with the screen throwing end; judging whether a working channel of a first connection interface between the screen throwing end and the first connection interface is an optimal channel according to the negotiation result; if the working channel of the first connection interface is the optimal channel, the negotiation result is saved; and transmitting the screen projection data by using the optimal channel according to the negotiation result. Because the non-optimal channel is not stored in the negotiation result, when the channel efficiency used in the first negotiation result is lower, the next screen-throwing can renegotiate, thereby solving the problem that the same equipment always performs data transmission on the channel with lower efficiency in the screen-throwing process, and realizing the technical effect of improving the data transmission efficiency. In addition, because the optimal channel is stored, the channel with higher efficiency can be used for data transmission all the time in the screen throwing process, and the method is also beneficial to improving the picture quality in the screen throwing process and improving the user experience.
Further, in another embodiment of the present invention, the method further includes:
And step S60, carrying out networking negotiation with the screen throwing end according to the networking request initiated by the screen throwing end.
In this embodiment, the networking request is a request for establishing a peer-to-peer network. The screen-throwing end and the screen-throwing end transmit the screen-throwing data, and the peer-to-peer network is established, so that networking negotiation is required according to a networking request initiated by the screen-throwing end, and a working channel for transmitting the screen-throwing data is selected.
Specifically, for example, when a networking request of a screen-throwing end is received, equipment identification information of the screen-throwing end is obtained; judging whether a screen-thrown end stores a history negotiation result corresponding to the screen-thrown end according to the equipment identification information, and if so, directly acquiring the history negotiation result; if not, carrying out networking negotiation with the screen throwing end.
In this embodiment, the networking negotiation is performed with the screen-throwing end according to the networking request initiated by the screen-throwing end. Because whether the history negotiation result with the screen throwing end is stored in the screen throwing end can be judged according to the networking request, and the negotiation result is directly obtained when the history negotiation result is stored, the networking negotiation time is saved, and the speed of establishing the screen throwing connection is facilitated to be increased.
Optionally, step S60, performing networking negotiation with the screen-throwing end according to the networking request initiated by the screen-throwing end, includes:
step S61, selecting the working channel of the first connection interface as a group manager in the process of establishing peer-to-peer network connection with the screen throwing end.
In this embodiment, the group manager is GO (Group Owner), which is used to determine the working channel to be used, i.e. the screen-cast end is made to be the GO, so as to actively select the working channel of the screen-cast connection interface.
Specifically, for example, as shown in fig. 3, go_interval (with maximum intention value 15, minimum value 0, default value 7) of the screen-cast end is set to 14 (corresponding to the step of setting go_interval of the television end to 14 in fig. 3), so that the screen-cast end is used as a group manager as far as possible in the process of establishing peer-to-peer network connection by the screen-cast end, so as to select the working channel of the first connection interface for further performing other steps in fig. 3.
According to the embodiment, the screen-thrown end is used as a group manager to actively select the working channel of the first connection interface, and the working channel of other network connection interfaces can be acquired, so that when the working channel of the first connection interface is selected, the working channel which can interfere with other network connection interfaces can be avoided, and the technical effect of negotiating the working channel with higher transmission efficiency in the networking negotiation process is achieved.
Further, in another embodiment of the screen-projection channel optimization method of the present invention, step S20 of determining whether the working channel of the first connection interface with the screen-projection end is an optimal channel according to the negotiation result includes:
Step S21, acquiring a working channel of a second connection interface between the working channel and an external network;
In this embodiment, the second connection interface is an interface that the screen-cast terminal connects to an external network, for example, when the screen-cast terminal is a television, the second connection interface may be an interface that the television connects to the router.
Specifically, for example, current wifi connection information is obtained, and a working channel of a second connection interface between the current wifi connection information and an external network is obtained.
Step S22, judging whether the working channel of the first connection interface and the working channel of the second connection interface belong to the same frequency band;
In this embodiment, the frequency band refers to the frequency range of the radio wave, specifically includes two frequency bands of 2.4G and 5G, and the channel is a data signal transmission channel using a wireless signal as a transmission carrier, and there are different channels in the same frequency band. For example, the 2.4G band in our country typically includes 13 channels. It is therefore necessary to determine whether the working channels of the two interfaces are in the same frequency band.
Step S23, if the working channels do not belong to the same frequency band, the working channels of the first connection interface are judged to be the optimal channels.
In this embodiment, if the working channels of the two interfaces do not belong to the same frequency band, for example, the first connection interface works in the 5G frequency band, and the second connection interface works in the 2.4G frequency band, the performance of the dual-reception dual-transmission wifi module can be exerted to the greatest extent at this time, and the interference of audio and video data transmission is reduced, so that higher transmission efficiency is achieved, and the working channel of the first connection interface is the optimal channel at this time.
Optionally, step S22, after determining whether the working channel of the first connection interface and the working channel of the second connection interface belong to the same frequency band, further includes:
step S24, if the working channels belong to the same frequency band, judging whether the working channel of the first connection interface and the working channel of the second connection interface belong to the same channel;
In this embodiment, when the working channels of the two interfaces belong to the same frequency band, for example, both are 5G frequency bands or both are 2.4G frequency bands, it is further required to determine whether the working channels of the two interfaces belong to the same channel.
Step S241, if the channels belong to the same channel, determining that the working channel of the first connection interface is the optimal channel.
In this embodiment, if the working channels of the two interfaces are the same channel, for example, the working channels of the two interfaces are both channels 6 in the 2.4G frequency band, then the wifi module only needs to work in one channel at this time, and frequent frequency hopping is not needed, so that the working performance of the 2 interfaces is not affected at this time, so that the working channel of the first connection interface is determined to be the optimal channel at this time, and the negotiation result is automatically saved at a later time.
Optionally, step S24, if the working channels belong to the same frequency band, determines whether the working channel of the first connection interface and the working channel of the second connection interface belong to the same channel, and further includes:
Step S242, if the channels do not belong to the same channel, determining that the working channel of the first connection interface is not the optimal channel.
In this embodiment, if the working channels of the two interfaces are not the same channel, for example, the working channel of the first connection interface is channel 6 in the 2.4G frequency band, and the working channel of the second connection interface is channel 1 in the 2.4G frequency band, because the wifi module needs to hop back and forth between different channels in the same frequency band at this time, the working performance of the 2 interfaces will be affected at the same time, so the transmission efficiency of the working channel of the first connection interface at this time will also be lower, so it is determined that the working channel of the first connection interface is not the optimal channel at this time, and the negotiation result at this time is discarded and stored in the subsequent steps.
For better understanding of the above embodiments, referring to fig. 3, the executing body (i.e. the screen-to-be-screened end) is the tv end, and in the networking negotiation process, the GO content of the tv end is set to be 14; recording a negotiation channel ChanP p0 (i.e. a working channel of a first connection interface) after networking negotiation is completed, and judging whether ChanWlan0 (i.e. a working channel of a second connection interface) and ChanP p0 belong to the same frequency band; if not, the negotiation configuration is saved (namely, the negotiation result is saved); if yes; then determine ChanWlan0 and ChanP2p0 if they belong to the same channel; if the same channel is used, the negotiation configuration is saved, and if the same channel is not used, the negotiation configuration is abandoned.
According to the method and the device, the working channel of the second connection interface of the screen-thrown end connected with the external network and the working channel of the first connection interface of the screen-thrown end connected with the screen-thrown end in the negotiation result are obtained, whether the working channel of the first connection interface is an optimal signal or not is judged, so that whether the negotiation result is saved is judged, the negotiation result when only the working channel of the first connection interface is the optimal channel is realized, and the phenomenon that the same equipment always performs data transmission on a channel with lower efficiency in the screen-throwing process due to the fact that the negotiation result is saved when the non-optimal channel is avoided. In addition, since automatic judgment of whether to perform the save operation is realized without manual judgment or operation, the technical effect of simplifying the operation is also realized.
