That is, the terminal device 100 may be understood as a video source device provided with a video capture component.

In particular, the terminal equipment may be mobile terminals such as mobile telephones (or so-called "cellular" telephones) and computers with mobile terminals, e.g. mobile devices which may be portable, pocket, hand-held, computer-included or vehicle-mounted, which exchange language and/or data with a radio access network; the terminal device may also be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a tablet computer, a Wireless modem (modem), a handheld device (handset), a laptop computer (laptop computer), a Machine Type Communication (MTC) terminal, or the like; the Terminal Device may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), a User Device or User Equipment, and the like, and the embodiments of the present application are not limited thereto.

The Display device 400 may be used to represent a device for displaying a video, such as a Liquid Crystal Display (LCD), a Light Emitting Diode (LED) Display, an Organic Light Emitting Display (OLED) Display, and the like, which is not limited in the embodiments of the present application.

It should be noted that the above example is only used to exemplarily illustrate application scenarios to which the wireless signal-based video control method according to the embodiment of the present application may be applied, and is not to be construed as a limitation to the application scenarios of the wireless signal-based video control method according to the embodiment of the present application.

For example, the application scenario of the video control method based on wireless signals according to the embodiment of the present application may be applicable to different network systems, such as Narrow Band-Internet of Things (NB-IoT), Global System for Mobile Communications (GSM), Enhanced Data rate GSM Evolution (Enhanced Data rate for GSM Evolution), Wideband Code Division Multiple Access (EDGE) WCDMA), Code Division Multiple Access (Code Division Multiple Access, CDMA2000), Time Division-synchronous Code Division Multiple Access (emd-Synchronization Code Division Multiple Access, TD-SCDMA), Long Term Evolution (Long Term Evolution, LTE), bluetooth System, WiFi System, and triple application scenarios, such as url, bb, llc and llc of 5G Mobile communication System.

As another example, elements may be adaptively added or subtracted in an application scenario such as that shown in FIG. 1, such as a server may be integrated with a display device, and so forth.

It should be noted that, in the embodiment of the present application, the terminal device 100 and the base station 200 are connected through a wireless network, for example, the terminal device 100 is connected to the base station 200 through an air interface, the terminal device 100 may send a video to the base station 200 based on a wireless signal provided by the wireless network, the base station 200 forwards the video to the server 300, the server 300 processes the video and sends the video to the display device 400, and the display device 400 displays the video.

When the display device 400 displays video, situations such as video jamming and screen splash are likely to occur, and in the related art, in order to avoid video jamming and screen splash, a video control method is generally adopted: the server determines the packet loss rate and the like of the video, and sends adjustment information for indicating the terminal equipment to adjust the video to the terminal equipment according to the packet loss rate and the like.

However, by the video control method in the related art, the reason causing the packet loss rate cannot be determined, that is, the reasons of video blocking, screen splash and the like cannot be accurately determined, so that the terminal device cannot correctly adjust the video, and the playing quality of the video is poor.

The inventor of the application obtains the inventive concept of the application through creative work: the attribute information of the wireless signal is determined by the location information of the terminal device, and an instruction message for adjusting or interrupting the video is generated according to the attribute information.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

According to an aspect of the embodiments of the present application, the embodiments of the present application provide a video control method based on a wireless signal, which may be applied to an application scenario as shown in fig. 1, and which may be applied to a server as shown in fig. 1.

Referring to fig. 2, fig. 2 is a flowchart illustrating a video control method based on wireless signals according to an embodiment of the present application.

As shown in fig. 2, the method includes:

s101: and the server receives the position information sent by the terminal equipment.

That is, the terminal device may acquire the location information where it is located, and transmit the acquired location information to the server.

The embodiment of the application does not limit the way for the terminal device to acquire the position information.

S102: and the server determines the attribute information of the wireless signal used for transmitting the video by the terminal equipment according to the position information.

The attribute information may be used to characterize information related to the wireless signal, such as information related to signal quality of the wireless signal, information related to signal strength of the wireless signal, information related to signal capability of the wireless signal, and the like, which is not limited in this embodiment.

S103: and the server generates and sends an indication message to the terminal equipment according to the attribute information, wherein the indication message is used for indicating the terminal equipment to adjust or interrupt the video.

That is to say, the server may generate the indication message according to the attribute information, and may understand the indication message from two dimensions, where one dimension is a dimension for adjusting the display quality of the video, that is, the indication message may be used to instruct the terminal device to adjust the video, and in some embodiments, the indication message may include the adjustment information, so that the terminal device adjusts the video based on the adjustment information; another dimension is the dimension in which the display of the video is stopped, i.e. the indication message may be used to instruct the terminal device to interrupt the video.

It should be noted that, in the related art, since the video backhaul (i.e., the video collected by the terminal device is sent to the server through the base station and displayed on the display device through the server) is a service of an application layer of the server, and a service transmission channel is mainly used between the application layer and the terminal device, and there is no mechanism of wireless signal transmission, it is difficult to think of analyzing the reason causing the poor video quality by combining the attribute information of the wireless signal itself without creative labor, and the inventor of the present application, after creative labor, conceives by inventing: the server determines the attribute information by combining the position information of the terminal equipment, thereby realizing the analysis of the reason causing the poor video quality from the characteristics of the wireless signal, realizing the accuracy and reliability of the analysis of the reason causing the poor video quality, further improving the technical effects of the stability and the reliability of video display, and realizing the technical effects of saving the cost of software and hardware without matching a private interface and a private signaling flow on the terminal equipment.

Referring to fig. 3, fig. 3 is a flowchart illustrating a video control method based on wireless signals according to another embodiment of the present application.

As shown in fig. 3, the method includes:

s201: and the server receives the position information sent by the terminal equipment.

For the description of S201, reference may be made to S101, which is not described herein again.

S202: and the server determines attribute information of a wireless signal used for transmitting the video by the terminal equipment according to the position information, wherein the attribute information comprises link path loss and/or signal strength.

For a part of the description about S202, refer to S102, which is not described herein again, and in this embodiment, the attribute information is further described, where the attribute information may be link loss, signal strength, or both link loss and signal strength.

S203: if the attribute information meets a preset first preset condition, the server generates and sends an indication message to the terminal equipment, wherein the first preset condition comprises:

the link path loss is greater than a preset path loss threshold; and/or

The signal strength is less than a preset strength threshold.

Wherein, this step can include: the server judges whether the attribute information meets a first preset condition, if so, an indication message is generated and sent to the terminal equipment; if not (i.e., the attribute information does not satisfy the first preset condition), the process returns to S201.

In some embodiments, if the first preset condition is that the link path loss is greater than a preset path loss threshold, the step may specifically include: the server judges whether the link path loss is greater than a path loss threshold value, and if so, an indication message is generated; if not (i.e., the link path loss is less than or equal to the path loss threshold), the process returns to S201.

In some embodiments, if the first preset condition is that the signal strength is greater than a preset strength threshold, the step may specifically include: the server judges whether the signal strength is greater than the strength threshold value, if so, an indication message is generated; if not (i.e., the signal strength is less than or equal to the strength threshold), then return is made to S201.

In some embodiments, if the first preset condition is that the link path loss is greater than a preset path loss threshold, and the signal strength is less than a preset strength threshold, the step may specifically include: the server judges whether the link path loss is greater than a path loss threshold value, if so, the server continuously judges whether the signal strength is greater than a strength threshold value, and if so, the server generates an indication message; if the link path loss is greater than or equal to the path loss threshold, or the signal strength is greater than or equal to the strength threshold, the process returns to S201. The embodiment of the present application does not limit whether the server first determines that the link path loss is greater than the path loss threshold, or whether the signal strength is greater than the strength threshold.

The path loss threshold and/or the strength threshold may be set by the server based on a requirement, a history, a test, and the like, which is not limited in the embodiment of the present application.

Now, taking an example in which the path loss threshold is set by the server based on the requirement, the following explanation is made:

the demand can be used for representing the demand of the display quality of the video preset in the server, and the server can select a relatively low path loss threshold value aiming at the demand of relatively high display quality so as to improve the quality of video display; conversely, the server may select a relatively high path loss threshold for a demand that the display quality is relatively low.

Now, taking an example in which the path loss threshold is set by the server based on the history, the following explanation is made:

the server knows from the history that the display quality of the video is relatively high when the road loss threshold is a certain section, and the server can determine the road loss threshold based on the section.

Taking the example of the road loss threshold value being selected by the server based on the experiment, the following explanation is made:

in the test stage, a plurality of threshold intervals are preset in the server. The server respectively generates the display quality of the video in the test stage based on each threshold interval, and sets a path loss threshold based on the display quality of the video in each test stage.

It should be noted that the above examples are only used for exemplary illustration, and the server sets the possible implementation manner of the path loss threshold, and is not to be construed as limiting the embodiments of the present application.

For the principle of setting the intensity threshold by the server, reference may be made to a method for setting a path loss threshold by the server, and details are not described here.

Based on S203, if the attribute information satisfies the first preset condition, the server may generate and send an indication message to the terminal device, and when the content of the indication message is different (for example, the indication message may be used to indicate the terminal device to adjust the video, or may be used to indicate the terminal device to interrupt the video), the path loss threshold and/or the intensity threshold set by the server may be different, now taking the path loss threshold as an example, the indication message triggering the server to generate different content is exemplarily described, where the path loss threshold includes a first path loss threshold and a second path loss threshold, and the first path loss threshold is smaller than the second path loss threshold:

if the server determines that the link path loss is larger than the first path loss threshold and the link path loss is smaller than the second path loss threshold, generating and sending an indication message for indicating the terminal equipment to adjust the video to the terminal equipment; and if the server determines that the link path loss is greater than the first path loss threshold and the link path loss is greater than or equal to the second path loss threshold, generating and sending an indication message for indicating the terminal equipment to interrupt the video to the terminal equipment. For example:

the server judges whether the link path loss is larger than a first path loss threshold value or not, if so (namely the link path loss is larger than the first path loss threshold value), the server continuously judges whether the link path loss is smaller than a second path loss threshold value or not, and if so (the link path loss is smaller than the second path loss threshold value), an indication message for indicating the terminal equipment to adjust the video is generated and sent to the terminal equipment; and if the server judges that the link path loss is greater than or equal to the second path loss threshold value, generating and sending an indication message for indicating the terminal equipment to adjust the video to the terminal equipment.

Taking the strength threshold as an example, the exemplary description is made on the indication message that triggers the server to generate different contents, where the strength threshold includes a first strength threshold and a second strength threshold, and the first strength threshold is smaller than the second strength threshold:

if the server determines that the signal intensity is greater than the first intensity threshold and the signal intensity is less than the second intensity threshold, generating and sending an indication message for indicating the terminal equipment to adjust the video to the terminal equipment; and if the server determines that the signal intensity is greater than the first intensity threshold and the signal intensity is greater than or equal to the second intensity threshold, generating and sending an indication message for indicating the terminal equipment to interrupt the video to the terminal equipment. For example:

the server judges whether the signal intensity is greater than a first intensity threshold value, if so, the server continues to judge whether the signal intensity is less than a second intensity threshold value, and if so, an indication message for indicating the terminal equipment to adjust the video is generated and sent to the terminal equipment; and if the server judges that the signal intensity is greater than or equal to the second intensity threshold value, generating and sending an indication message for indicating the terminal equipment to interrupt the video to the terminal equipment.

The description of the server determining to generate the indication message with different contents based on the two dimensions of the path loss threshold and the strength threshold may be combined with the above-mentioned principle of the example described from a single dimension, and is not repeated here.

Referring to fig. 4, fig. 4 is a flowchart illustrating a video control method based on wireless signals according to another embodiment of the present application.

As shown in fig. 4, the method includes:

S4: and the server acquires the link path loss and/or the signal strength according to the position information and the strategy determined by the S3.

For example, the server determines a propagation model by determining parameters such as a basic propagation model and propagation model compensation, and performs link budget and/or signal estimation and the like according to the propagation model to generate link path loss and/or signal strength.

It should be noted that, reference may be made to the related art for specific implementation of link budget and/or signal estimation, and the embodiments of the present application are not limited thereto.

That is, in some embodiments, the policy employed by the server to generate the indication message may be different for different serving cells.

For example, in some embodiments, the policy determined based on S8 includes: generating the indication message by means of a single threshold, S9 may include:
