All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a control method of a multi-channel video call, which is applied to a multi-channel terminal, and as shown in figure 1, the method comprises the following steps:
s11, in the process of multi-path video call, when a new video call request is received, obtaining the values of the various influence parameters influencing the load-bearing capacity of the video call at present.
And S12, controlling the establishment of a new video call according to the values of the influence parameters.
In the multi-channel video call control method provided by the embodiment of the invention, in the multi-channel video call process, when a new video call request is received, the values of all the influence parameters influencing the bearing capacity of the video call at present are obtained, and the establishment of the new video call is controlled according to the values of all the influence parameters. Compared with the prior art, the method and the device can comprehensively evaluate whether the new call can be born or not according to the influence parameters influencing the bearing capacity of the video call before the new video call is established, and avoid blindly adding the new call, thereby ensuring the quality of the video call.
Wherein, step S12 may further include:
and S121, judging the video call establishment permission level corresponding to each influence parameter value.
Specifically, the value of the impact parameter may be compared with a preset level threshold, and a corresponding video call establishment permission level is determined according to the comparison result, where different impact parameters correspond to different level thresholds, and each impact parameter corresponds to at least two level thresholds.
And S122, establishing an allowable grade according to the video call corresponding to the value of each influence parameter, and comprehensively judging the allowable grade for establishing a new video call.
Specifically, the lowest one of the video call establishment permission levels corresponding to the values of each impact parameter may be used as the permission level for establishing a new video call.
And S123, controlling the establishment of the new video call according to the permission level of the new video call.
Specifically, when the permission level of the new video call is the lowest level, the establishment of the new video call is refused; and when the permission level of the new video call is not the lowest level, establishing the new video call according to the effect corresponding to the permission level of the new video call.
Further, when the allowable level of the new video call is the lowest level, a prompt that the new video call cannot be established can be sent to the user.
Further, when the allowable level of the new video call is the lowest level, one or more current video calls can be disconnected to release resources to carry the new video call.
The following describes the control method of the multi-channel video call in detail by using a specific example.
The factors affecting the video call carrying capacity can be divided into two aspects of terminal performance and environmental performance. The terminal performance refers to the processing capability of the terminal itself, and mainly includes the processing capabilities of a voice processor, a video processor, a CPU, a memory, and the like. Wherein,
a voice processor (Audio processor) is a unit in a terminal that specially processes voice. In multi-path communication, the work of coding, sending, decoding, mixing, playing and the like of a plurality of code streams needs to be processed simultaneously. The corresponding influence parameter of the voice processor is the processing number (R) of the voice streamA). The number of allowable voice stream processes for a single terminal is limited.
VideoThe processor (Video processor), similar to the speech processor, needs to process multiple paths of Video data simultaneously, control Camera acquisition and Video encoding. The impact parameter for a video processor is the number (R) of video streams processed simultaneously at a certain processing delay (e.g. maximum 100ms)V)。
The CPU is a core scheduling module for all operations of the terminal, and the processing capacity and real-time burden condition of the CPU are key to the situation that a new call cannot be established. The corresponding influencing parameter of the CPU is the current idle processing capacity (R)c)。
All processing and calculation consume a certain amount of memory, so that there is no way to establish a new call even if the memory is insufficient. The influencing parameter corresponding to the memory is the free amount (R) of the current memoryM)。
The environment performance refers to the performance of the wireless network environment where the terminal is currently located, and mainly refers to real-time data transmission capability. The transmission capabilities of LTE networks and WiFi networks are referred to in VoLTE and VoWiFi, respectively.
In an LTE network, when a terminal communicates using a VoLTE mode, it is necessary to transmit and receive data between an LTE module of the terminal and a base station. Each additional call requires one or more dedicated bearers to be established. At this time, the corresponding impact parameter is the transmission capability (R) of the LTE networkL)。
Under the WiFi network, when the terminal uses the VoWiFi mode to communicate, data transmission and reception between the WiFi module of the terminal and the WiFi hotspot may be required. At this time, the corresponding impact parameter is the transmission capability (R) of the WiFi networkW)。
For each of the above-mentioned influencing parameters, three critical values, optimum, medium and minimum, are set.
Optimum critical value (R)max) The method refers to the value of the impact parameter required to achieve the best video call effect, and when the value of the impact parameter is greater than the optimal critical value, the video call effect is the best.
Intermediate critical value (R)mid) The method is to indicate a value of an impact parameter that needs to be achieved to achieve a medium video call effect, and when the value of the impact parameter is greater than or equal to a medium critical value and less than an optimal critical value, the effect of the video call is slightly poor relative to the optimal effect, for example, the video resolution and the code rate are reduced, so that the consumption of system resources can be correspondingly reduced, and the purpose of considering both performance and experience is achieved.
Minimum critical value (R)min) The method refers to a value of an influence parameter which needs to be reached to achieve a poor video call effect, when the value of the influence parameter is greater than or equal to a minimum critical value and smaller than a medium critical value, the effect of the video call is slightly poor relative to the medium effect, user experience is slightly influenced, but the method can be accepted under the condition that certain delay, packet loss or fuzziness can occur, and the method is the minimum requirement which must be reached by video call establishment. When the value of the impact parameter is below a minimum threshold, a video call cannot be established.
And when a new video call request is received, obtaining the values of the influence parameters, and then judging the video call establishment permission level corresponding to the value (R) of each influence parameter. The specific judgment method is as follows:
when R < RminAnd then, judging that a new video call cannot be established.
When R ismin≤R＜RmidThen it is decided that the video call can be established with minimal effect.
When R ismid≤R＜RmaxIt is decided that the video call can be established with a medium effect.
When R > RmaxIt is decided that the video call can be established with the best effect.
Then, whether a new video call can be established or not and the effect of the new video call that can be established when it is determined that the new video call can be established are comprehensively determined according to the determination result corresponding to the value (R) of each influence parameter.
Specifically, when the judgment result corresponding to the value (R) of one of the impact parameters is that a new video call cannot be established, the terminal rejects the establishment of the new video call regardless of the judgment results corresponding to the values (R) of the other impact parameters, and simultaneously may send a prompt that the new video call cannot be established to the user, or may disconnect one or more current video calls to release resources to carry the new video call.
And when the judgment result corresponding to the value (R) without the influence parameter is that the new video call cannot be established, establishing the new video call according to the lowest effect in the judgment results corresponding to the values (R) of all the influence parameters.
