Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
Aiming at the technical problems that in the prior art, in the process of network video call, video call pictures are not clear, the phenomena of unsmooth video call images such as blurring, blocking, and screen splash display occur, and the network call quality cannot be actually improved only by adjusting video call parameters, window sizes and other modes, the application provides a network video call method, wherein a first carrier bandwidth segment BWP is adopted to carry out network video call, the call fluency of the network video call is detected, if the call fluency meets set conditions, whether the communication state is abnormal or not is judged, and if the communication state is abnormal, a second BWP is adopted to carry out the network video call; wherein the communication capacity of the second BWP is greater than the communication capacity of the first BWP.
The network video call method, device and electronic equipment according to the embodiments of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a schematic flowchart of a network video call method according to an embodiment of the present application.
The embodiment of the present application is exemplified by the network video call method being configured in a network video call device, and the network video call device can be applied to any electronic equipment, so that the electronic equipment can execute a video call function.
The electronic device may be a Personal Computer (PC), a cloud device, a mobile device, and the like, and the mobile device may be a hardware device having various operating systems, such as a mobile phone, a tablet Computer, a Personal digital assistant, a wearable device, and an in-vehicle device.
As shown in fig. 1, the network video call method includes the following steps:
Wherein, BWP is called Bandwidth Part in english, that is, a Part of Bandwidth. We also sometimes refer to this technique, Bandwidth Adaptation, with Bandwidth Adaptation.
In the embodiment of the application, when a user uses the electronic device to perform a network video call, the network side of the electronic device allocates the first carrier bandwidth segment BWP to the electronic device, so that the network video call can be performed between the electronic devices.
It should be noted that, the electronic device performs a network video call by using a fifth Generation Mobile communication technology (5G for short), and the electronic device performs the network video call by using a proper bandwidth, that is, the first BWP. When the electronic device performs network video call on the corresponding BWP, only the corresponding central frequency point and sampling rate need to be adopted, and each BWP is not only different in frequency point and bandwidth, but also can correspond to different configurations. For example, the subcarrier spacing, Single Side Band (SSB) period, etc. of each BWP may be configured differently to meet different service requirements.
In the embodiment of the application, the electronic device may monitor the communication fluency of the video call during the network video call by using the first BWP, so as to determine whether the electronic device has the situations of low communication fluency, such as blur, splash screen, mosaic, and the like, during the network video call.
As a possible implementation manner, the call fluency of the network video call may be determined according to a frame loss rate in the process of performing the network video call by using the first BWP.
As another possible implementation manner, the call fluency of the network video call may also be determined according to a content loss ratio of a single frame of picture in the process of the network video call by the electronic device using the first BWP.
As another possible implementation manner, during the network video call by the electronic device using the first BWP, the call smoothness of the network video call may be determined according to the frame loss rate of the network video call and the content loss ratio of the single frame in the network video call.
It should be noted that, in the embodiment, the method is not limited to the above method when detecting the smoothness of the network video call, and other methods that may detect the smoothness of the network video call are also applicable to the embodiment, which is not limited in the embodiment.
And 103, judging whether the communication state is abnormal or not if the communication fluency meets the set condition.
In a possible situation, when the electronic device performs the network video call and detects that the call fluency of the network video call does not meet the set condition, indicating that the electronic device performs the network video call using the carrier bandwidth of the current communication capacity and the call effect is better, the electronic device continues to perform the network video call by using the first BWP.
In another possible situation, when the electronic device performs the network video call and detects that the call smoothness of the network video call meets the set condition, further, whether the communication state is abnormal is judged to judge whether to switch the bandwidth adopted in the network video call.
For example, the setting condition may be that the call fluency of the network video call is lower than a call fluency threshold, the call fluency threshold may be preset according to the network video call quality, and when the call fluency is lower than the call fluency threshold, whether the communication state is abnormal or not is determined.
As a possible implementation manner, when determining the call smoothness of the network video call by using the frame dropping rate in the process of performing the network video call by using the first BWP, when determining that the frame dropping rate of the video call within the preset duration is greater than the preset frame dropping rate, it may be determined that the call smoothness of the network video call satisfies the set condition.
As another possible implementation manner, when determining the call fluency of the network video call by using the content loss ratio of the single frame image in the network video call in the process that the electronic device performs the network video call by using the first BWP, when determining that the content loss ratio of the single frame image in the network video call is greater than the preset loss ratio, it may be determined that the call fluency of the network video call satisfies the set condition.
As another possible implementation manner, when the frame loss rate of the network video call and the content loss ratio of the single frame picture in the network video call are simultaneously used to determine the call smoothness of the network video call during the network video call by using the first BWP, when it is determined that the frame loss rate of the network video call is greater than the preset frame loss rate and the content loss ratio of the single frame picture is greater than the preset loss ratio, it may be determined that the call smoothness of the network video call satisfies the setting condition.
In the embodiment of the application, when it is detected that the call fluency of the electronic device using the first BWP to perform the network video call meets the set condition, further, the packet loss rate may be determined by counting Real-time Transport Protocol (RTP) packets transmitted between the electronic device and the network side, and then whether the communication state is abnormal or not may be determined according to the packet loss rate. The packet loss rate is a ratio of the number of lost packets to the number of transmitted data packets.
Wherein the bandwidth of the second BWP is larger than the bandwidth of the first BWP, and/or the subcarrier spacing of the second BWP is larger than the subcarrier spacing of the first BWP. Therefore, when the electronic device performs the network video call by using the second BWP, the communication rate and the group utilization rate can be improved.
As a possible scenario, the Network side device may be a Radio Network Controller (RNC).
In the embodiment of the application, when the real-time transmission data packets are counted and the packet loss rate is higher than the set packet loss threshold, it is determined that the communication state is abnormal.
It should be explained that the fluency reduction of the network video call may be caused by network reasons or factors at the electronic equipment end, and therefore, the reason of the fluency reduction of the network video call needs to be determined by whether the communication state is abnormal or not.
After determining that the communication state is abnormal, the electronic device further detects whether a bandwidth with a communication capacity higher than that of the first BWP exists in each BWP already allocated by the network-side device, and in the case that it is determined that the bandwidth allocated by the network-side device exists in the second BWP with a communication capacity higher than that of the first BWP, the electronic device transmits a bandwidth switching request to the network-side device. After receiving the switching request sent by the electronic device, the network-side device switches the bandwidth of the electronic device to a second BWP with a bandwidth higher than the first BWP when receiving the switching response sent by the network-side device, so as to perform the network video call by using the second BWP. Therefore, the second BWP with higher communication capacity is used for carrying out the network video call, and the call smoothness of the network video call of the electronic equipment can be improved.
It should be noted that, in NR (New Radio, New air interface), a bandwidth of an electronic device for performing a network video call may be dynamically changed, a carrier bandwidth may be divided into multiple BWPs, and one electronic device may be configured with multiple BWPs at the same time, but only one activated BWP may be on one carrier by one electronic device at the same time. If the electronic device is configured with multiple carriers, there may be one active BWP on each carrier. When the call fluency of the first BWP currently adopted by the electronic device for the network video call cannot meet the user requirement and there is a communication abnormality on the network side, the network-side device needs to be requested to switch the BWP with higher communication capacity to adopt a second BWP with higher communication capacity than the first BWP for the network video call.
The network video call method of the embodiment of the application adopts a first carrier bandwidth segment BWP to carry out network video call; detecting the call fluency of the network video call; if the call fluency meets the set conditions, judging whether the communication state is abnormal; if the communication state is abnormal, a second BWP is adopted for network video call; wherein the communication capacity of the second BWP is greater than the communication capacity of the first BWP. Therefore, whether the communication state of the network side is detected or not is triggered through the communication fluency of the network video call, when the communication state of the network side is abnormal, the network side is requested to switch the BWP with higher communication capacity, so that the network video call can be clearer and smoother, and the technical problem of poor visual experience of a user when the network video call quality is improved through adjusting video call parameters, window sizes and other modes in the prior art is solved.
On the basis of the foregoing embodiment, after step 104, when the electronic device performs the network video call by using the second BWP, and when it is detected that the call fluency of the video call is higher than the call fluency threshold, the electronic device requests the network-side device to switch back from the second BWP to the first BWP, so as to continue to perform the network video call by using the first BWP, thereby reducing the power consumption of the electronic device. Next, the above processes are described in detail with reference to the second embodiment, and fig. 2 is a schematic flow chart of a network video call method according to the second embodiment of the present application.
As shown in fig. 2, after step 104, the network video call method may further include the following steps:
In the embodiment of the application, when the electronic device performs the network video call by using the second BWP allocated by the network-side device, the call fluency of the network video call by using the second BWP is continuously detected, so as to determine whether situations with lower call fluency, such as blur, screen splash, mosaic, and the like, exist in the electronic device when the network video passes through.
As a possible implementation manner, the call fluency of the network video call may be determined according to a frame loss rate in the process that the electronic device performs the network video call by using the second BWP.
As another possible implementation manner, the call fluency of the network video call may also be determined according to a content loss ratio of a single frame of picture in the process of the network video call by the electronic device using the second BWP.
As another possible implementation manner, during the network video call by the electronic device using the second BWP, the call fluency of the network video call may be determined according to the frame loss rate of the network video call and the content loss ratio of the single frame in the network video call.
It should be noted that, in the embodiment, the method is not limited to the above method when detecting the smoothness of the network video call, and other methods that may detect the smoothness of the network video call are also applicable to the embodiment, which is not limited in the embodiment.
In the embodiment of the application, whether the call smoothness of the network video call meets the set condition or not can be judged according to the call smoothness of the network video call determined in the process that the electronic device adopts the second BWP to carry out the network video call. Wherein, the setting condition can be that the call fluency is lower than the threshold value
As a possible implementation manner, when determining the call fluency of the network video call by using the frame dropping rate in the process that the electronic device performs the network video call by using the second BWP, when determining that the frame dropping rate of the video call within the preset duration is less than the preset frame dropping rate, it may be determined that the call fluency of the network video call is higher than the call fluency threshold.
As another possible implementation manner, when determining the call fluency of the network video call by using the content loss ratio of the single frame of picture in the network video call in the process that the electronic device performs the network video call by using the second BWP, when determining that the content loss ratio of the single frame of picture in the network video call is smaller than the preset loss ratio, it may be determined that the call fluency of the network video call is higher than the call fluency threshold.
As another possible implementation manner, when the frame loss rate of the network video call and the content loss ratio of the single frame picture in the network video call are simultaneously used to determine the call fluency of the network video call during the network video call by using the second BWP, when it is simultaneously determined that the frame loss rate of the network video call is less than the preset frame loss rate and the content loss ratio of the single frame picture is less than the preset loss ratio, it may be determined that the call fluency of the network video call is higher than the call fluency threshold.
And step 203, determining that the call fluency of the network video call does not meet the set condition, and continuing to adopt the first BWP to carry out the network video call.
In this embodiment, when the electronic device performs the network video call by using the second BWP and detects that the call fluency of the network video call is higher than the call fluency threshold, it may be determined that the call fluency becomes better when the electronic device switches to the second BWP with higher communication capacity to perform the network video call. In this case, the network-side device may be requested to switch back from the second BWP to the first BWP to continue the network video call using the first BWP.
In the embodiment of the application, when the electronic device performs the network video call by using the second BWP and detects that the call smoothness of the network video call is lower than the call smoothness threshold, further, the electronic device performs statistics on real-time transmission RTP data packets between the electronic device and the network side to determine a packet loss rate, and further determines whether the communication state is abnormal according to whether the packet loss rate is higher than a set packet loss threshold.
According to the network video call method, whether the call fluency of the network video call meets the set condition is judged by detecting the call fluency of the network video call by adopting the second BWP, when the call fluency of the network video call does not meet the set condition is determined, the network video call is continuously carried out by adopting the first BWP, and when the call fluency of the network video call meets the set condition is determined, whether the communication state is abnormal is detected. Therefore, when the electronic device adopts the second BWP to carry out the network video call and the call fluency during the network video call does not meet the set condition of the user, the first BWP is adopted to carry out the network video call, so that the intelligent switching of the BWP is realized, the network resource allocation is fully utilized, and the power consumption of the electronic device is reduced.
