Description

Method for selecting channel and related equipment thereof

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a channel selection method and related equipment thereof.

Background

There are two forms of smart televisions at present, one is that the host computer and the screen are designed as an integrated structure, and the other is that the host computer and the screen are designed in a split type. However, as the wireless image transmission technology in the consumer scene has not been broken through yet, the host computer and the screen adopting the split design still adopt the cable connection mode to transmit information. With the further development and maturity of wireless technology, the adoption of the wireless technology for information transmission between a host and a screen becomes a scene of a future intelligent television.

For example, when information is transmitted between a host and a screen through a wireless-fidelity (Wi-Fi) router, the Wi-Fi router itself usually performs channel quality assessment, and directly selects a channel with a better assessment result to transmit the information between the host and the screen; or in the connection stage, the host and the screen synchronously scan channels and adopt a random collision mode, if the host and the screen find each other on a certain channel, the host and the screen directly select to transmit information by adopting the corresponding channel, and the channel quality of the channel is not required to be evaluated.

However, when the two modes are adopted to select the channel and transmit the information between the host and the screen through the Wi-Fi router, the current channel quality evaluation result only reflects the channel quality condition at the current time point, and the future channel quality condition cannot be estimated, if the current channel is adopted to transmit the information between the host and the screen, once the current channel is interfered by the interference source, the display quality of the wireless image transmitted between the host and the screen is poor, and the user experience is poor.

Detailed Description

The following detailed description of the present application refers to the accompanying drawings, which illustrate only some, but not all, embodiments of the application. The terms "first," "second," "third," "fourth" and the like in the description and in the claims and in the above drawings, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

In the related art, when information transmission between a split host and a screen is performed, for example, through a Wi-Fi router, the Wi-Fi router itself usually performs channel quality evaluation, and directly selects a channel with a better evaluation result to transmit the information between the host and the screen; or in the connection stage, the host and the screen synchronously scan channels and adopt a random collision mode, if the host and the screen find each other on a certain channel, the host and the screen directly select to transmit information by adopting the corresponding channel, and the channel quality of the channel is not required to be evaluated. However, when the two modes are adopted and information between the host and the screen is transmitted through the Wi-Fi router, the current channel quality evaluation result only reflects the channel quality condition at the current time point, and the future channel quality condition cannot be estimated, if the current channel is adopted between the host and the screen to transmit the information, once the information is interfered by an interference source, the display quality of a wireless image transmitted between the host and the screen is poor, and the user experience is poor.

Referring to fig. 1, a schematic diagram of interference from an interference source is provided in the prior art. As can be seen from fig. 1, the preferred civil unlicensed band of 5GHz overlaps with the frequency corresponding to the channel for transmitting Wi-Fi data, and considering that the civil unlicensed band of 5GHz has weak wall-penetrating performance, the split host and the split two screens are easily affected by the channel for transmitting WiFi data in the 5G Hz band from the same room when transmitting information, for example: a home router A; it can also be seen from fig. 1 that the two screens in the split type are also additionally interfered by the neighboring router B. If the host or screen selects the same channel as home router a or neighbor router B, the display quality of the transmitted wireless image is greatly compromised by interference, resulting in a poor user experience.

It can be understood that, in addition to the interference caused by the home router a and the neighboring router B, the foregoing fig. 1 may be also affected by potential interference devices such as the home router C and the neighboring router D in practical applications, and in particular, the embodiment of the present application is not limited to the description.

In order to solve the above problems, the embodiments of the present application provide a method for selecting a channel, which aims to avoid channels used by potential interference devices such as home routers and neighbor routers, integrate evaluation results of channel quality used by a host and a screen, and finally select a target use channel. Fig. 2 is a schematic diagram of a split system architecture according to an embodiment of the application. As can be seen from fig. 2, the split system architecture may include a first device and at least one second device, where the first device and the at least one second device are both split devices, and the first device and each of the at least one second device are connected by wireless communication, such as: wi-Fi, bluetooth, etc.

It will be appreciated that the above-described split device may be applied to a game scene, a macro-screen viewing scene, etc., and the corresponding first device may include, but is not limited to, a host, etc., where the host may include, but is not limited to, a game console, a set-top box, a digital television (digital television, DTV), or a home theater device, etc.; the second device may include, but is not limited to, a screen or the like that can be used for display. In addition, the first device may also be connected to a wireless audio device, for example: sound, microphone, etc.

Furthermore, the number of the second devices in the at least one second device described is not particularly limited in the embodiment of the present application, and may be depending on the actual situation. For example, taking a second device as an example of a screen, fig. 3a shows a schematic diagram of a split screen combination. As shown in fig. 3a, in a game scene, three screens may be used to combine to display a game screen in the game scene, such as: game screen (left), game screen (middle), and game screen (right). In addition, fig. 3b shows a schematic view of another split screen combination. As shown in fig. 3b, in the macro-screen video scene, four screens may be used to display movie pictures in the macro-screen video scene, for example: movie picture (upper left), movie picture (upper right), movie picture (lower left), and movie picture (upper right).

Based on the system architecture provided in fig. 2, fig. 4 is a flow chart of a method for channel selection according to an embodiment of the present application, as shown in fig. 4, the method includes the following steps:

401. the second device evaluates the channel quality of the at least one channel used to obtain a first channel result reflecting the channel condition of the at least one channel used by the second device.

In an embodiment, the second device may include, but is not limited to, a screen or the like. And the second device, after completing connection with the first device through wireless communication or the like, may perform channel quality evaluation on at least one channel used by itself so as to obtain a first channel result. For example, for each of the at least one channel, the second device may extract various characteristic information from a signal from the signal source by capturing the signal, such as: standard deviation, kurtosis coefficient, inflection point, etc., and the quality condition of the channel where the signal is located is calculated and estimated by combining the various characteristic information. In this way, the second device can evaluate the quality condition of each channel in the at least one channel, thereby screening the channel with the quality reaching the standard.

It will be appreciated that the first channel results described may include each channel quality-qualified channel and the corresponding quality condition. Furthermore, the first channel result may be given by way of a first list (e.g., si_chan_list, where 1.ltoreq.i.ltoreq.n, n being a positive integer), such as:

si_chan_list table

Channel(s)	Quality condition
		64	5
128	5
		157	4
…	…

As can be seen from the si_chan_list table, the first channel result may include channel 64, channel 128, channel 157; and the respective corresponding mass conditions are 5, 5 and 4 respectively. Other channels with standard channel quality and corresponding quality conditions may also be included in the practical application, which are not limited herein.

402. The second device sends the first channel result to the first device.

In an embodiment, since the first device has a unified decision function, the second device needs to send the first channel result to the first device after evaluating the first channel result.

403. The third device queries at least one channel used by each of the at least two potentially interfering devices.

In an embodiment, the third device may include, but is not limited to, a router management device, a long-range home smart device, etc., and may manage at least two potential interfering devices, such as a home router and a neighbor router. Therefore, when the first device needs to know the channels used by at least two potential interference devices such as the home router, the neighbor router and the like, the first device can inquire and determine at least one channel used by at least two potential interference devices based on the inquiry request by sending the inquiry request to the third device; alternatively, the third device may actively query at least one channel used by each of the at least two potentially interfering devices during a periodic preset duration, which is not limited in the embodiment of the present application.

It is to be understood that the at least two potential interfering devices described may include at least one home router and at least one neighbor router.

404. The third device sends a second channel result to the first device, the second channel result being used to reflect channel conditions of at least one channel used by each of the at least two potentially interfering devices.

In an embodiment, after the third device queries at least one channel used by at least two potentially interfering devices, the at least one channel used by the at least two potentially interfering devices may be sent to the first device by way of a second channel result, so that the first device may receive the second channel result.

It will be appreciated that the second channel results described above may include at least one channel used by each of the at least two potentially interfering devices, and a corresponding quality condition for the channel. For example, the second channel result may include at least one channel used by the home router and a quality condition corresponding to the channel and at least one channel used by the neighbor router and a quality condition corresponding to the channel. For ease of understanding, the second channel result may also be given by means of a second list and a third list in the embodiment of the present application, where the second list (e.g., hap_list) may include at least one channel used by the home router and a quality condition corresponding to the channel, and the third list (e.g., nap_list) may include at least one channel used by the neighbor router and a quality condition corresponding to the channel, which is not limited in the embodiment of the present application.

For example, in some embodiments, the third device calculates the number of times each first identifier in the access list is scanned within a preset time period; and when the number of times the first identifier is scanned is greater than a preset threshold value, the third device determines that the device identified by the first identifier is a potential interference device. It is noted that the first identification described includes, but is not limited to, a service set identification (service set identifier, SSID).

For example, the third device may scan an Access Point (AP) list once every hour, and record the number of times each SSID is scanned in the AP list, if a certain SSID is scanned more than a preset threshold (e.g., m times, m > 0); the third device may record the device identified by the SSID as a neighbor router. In addition, the third device may record the channel last used by the neighboring router in the nap_list, as shown in the following table:

NAP_list table

SSID	Age	Recently used channels
			Huawei_A	60	64
Huawei_M	20	36
			…	…	…

As can be seen from the nap_list table, the neighbor routers may include huawei_a and huawei_m, where the last used channel identified by SSID huawei_a is 64 and the last used channel identified by SSID huawei_m is 36. The channels used by the devices identified by other SSID may also be included in the actual application, which is not limited herein.

405. The first device determines a third channel result reflecting channel conditions of the channel used by the first device.

The first device may also need to evaluate the channel quality of at least one channel used by itself, and the specific evaluation procedure may be understood in the manner described in step 401 above, which is not described here. In this way, the first device, after evaluating the channel quality of at least one channel used by itself, can obtain a third channel result, and the third channel result can be used to reflect the channel condition of the channel used by the first device.

It will be appreciated that in embodiments of the present application, the third channel result may also be provided by way of a fourth list (e.g., m_chan_list), where the fourth list may include at least one channel used by the first device and a quality condition corresponding to the channel,

in addition, it should be noted that, with respect to the execution sequence of the steps 401 to 402, 403 to 404, and 405 described above, the steps 403 to 404, 405 may be executed first, the steps 401 to 402 may be executed later, and so on in practical applications, and the execution sequence is not limited herein.

406. The first device selects a target usage channel based on at least one of the first channel result, the second channel result, and the third channel result, the target usage channel being used to transmit communication information between the first device and each of the second devices.

The first device, after learning at least one of the first channel result, the second channel result and the third channel result, may select a target usage channel from the at least one first channel result, the selected target usage channel is effectively a channel in the second channel result, so that the communication information between the first device and each second device can be transmitted by using the target usage channel, and the influence of the channel used by the potentially interfering device is avoided.

Specifically, selecting the target usage channel may be performed in the following manner: the first equipment determines an intersection of at least one first channel result and a third channel result to obtain a first operation result; the first equipment determines an intersection of the first operation result and a second channel result to obtain a second operation result; the first device selects a target usage channel from a difference set of the first operation result and the second operation result based on a quality condition of each channel in the difference set.

That is, it is understood that, since each first channel result includes at least one channel used by the corresponding second device, and each third channel result also includes at least one channel used by the corresponding first device, the first device may first intersect all first channel results and third channel results in the at least one first channel result to obtain a first operation result, where the first operation result may reflect a set of channels searched by the first device and each second device together; then, the first device acquires an intersection of the first operation result and a second channel result to obtain a second operation result, and the second operation result reflects a set of channels searched by the first device, each second device and a third device together; thus, in order to potentially interfere with the effects of the channels used by the device, the first device also needs to determine a set of differences between the first and second results, where each channel in the set of differences may be considered a candidate set of channels. In this way, the first device then selects the preferred channel as the target usage channel based on the quality condition of each channel in the difference set.

For ease of understanding, taking the example that the potentially interfering device includes one home router and one neighbor router, and describing the first channel result corresponding to the ith second device using the above-described first list (si_chan_list), the second list (hap_list) describes at least one channel used by the home router and the quality case corresponding to the channel, and the third list (nap_list) may describe at least one channel used by the neighbor router and the quality case corresponding to the channel, then the second channel result may be described using the second list and the third list, and the fourth list (m_chan_list) describes the third channel result. Thus, a specific channel selection algorithm is as follows:

D_chan_list＝M_chan_list∩S1_chan_list∩…∩Si_chan_list∩…∩Sn_chan_list；

pchan=max ((d_chan_list-d_chan_list ≡hap_list)), where d_chan_list represents the first operation result and Pchan represents the target usage channel.

In addition, in other embodiments, when the first device performs the exclusive-or operation based on the first operation result and the second channel result, and cannot obtain a corresponding result, then the first device may further delete at least one channel used by each of the at least two potential interference devices from the second channel result in turn according to a preset policy, so as to obtain a fourth channel result; then, the first device determines an intersection of the first operation result and the fourth channel result to obtain a second operation result.

That is, when the channel selection algorithm has no result, the first device may delete the channels in the second channel result in sequence according to a preset policy such as the interference strength of the interference source, and then further combine the first operation result to take the intersection. For example: according to the interference intensity of the neighbor router is smaller than that of the home router, corresponding channels are deleted in sequence from NAP_list to HAP_list, so that channels with strong interference can be eliminated conveniently.

It can be understood that, in practical application, if a certain second device cannot evaluate and obtain a first channel result (si_chan_list) with qualified channel quality due to the placement location, then the preset policy at this time may also be to select a channel with relatively better channel quality from candidate channels with unqualified channel quality and record the channel in the si_chan_list. It is understood that the channel quality described does not reach the standard, and it is understood that the channel quality does not reach the preset threshold, etc., and the description is not given here.

Alternatively, if d_chan_list=m_chan_list n s1_chan_list n … n si_chan_list n … n sn_chan_list in the above-described channel selection algorithm shows no result, then the preset policy at this time may also be to include the channel with the best average channel quality used by each second device into the respective list; or a weight value may be set for each second device, so that the second devices with low weight values are discarded, and a channel with better channel quality is selected from the second devices with high weight values as a result, and the preset policy is not limited herein.

407. The first device sends a first message to each of the second devices and a second message to the third device.

408. The second device transmits communication information with the first device in the target usage channel based on the indication of the first message.

In an embodiment, since the first message indicates that the second device transmits communication information with the first device in the target usage channel, the first message includes: wireless image, etc., then the second device, upon receiving the first message sent by the first device, may directly use the communication information between the target usage information transmission and the first device under the direction of the first message.
