The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present application and are not to be construed as limiting the present application.
Aiming at the technical problems that in the prior art, in the network video call process, video call pictures are not clear, and the phenomena of unsmooth display of video call images, blocking, screen display and the like occur, and the network call quality cannot be actually improved only by adjusting video call parameters, window size and the like, the application provides a network video call method, which comprises the steps of detecting the call smoothness of the network video call by adopting a first carrier bandwidth segment BWP to perform network video call, judging whether a communication state is abnormal if the call smoothness meets a set condition, and adopting a second BWP to perform network video call if the communication state is abnormal; wherein the communication capacity of the second BWP is larger than the communication capacity of the first BWP.
The following describes a network video call method, a device and an electronic device according to embodiments of the present application with reference to the accompanying drawings.
Fig. 1 is a flowchart of a network video call method according to an embodiment of the present application.
The network video call method is configured in a network video call device for example, and the network video call device can be applied to any electronic equipment so that the electronic equipment can execute video call functions.
The electronic device may be a personal computer (Personal Computer, abbreviated as PC), a cloud device, a mobile device, etc., and the mobile device may be a hardware device with various operating systems, such as a mobile phone, a tablet computer, a personal digital assistant, a wearable device, a vehicle-mounted device, etc.
As shown in fig. 1, the network video call method includes the following steps:
in step 101, a network video call is performed using the first carrier bandwidth segment BWP.
Wherein BWP, english is fully called Bandwidth Part, i.e. a Part of the Bandwidth. We sometimes refer to this technique, i.e. bandwidth adaptation, also by Bandwidth Adaptation.
In the embodiment of the application, when the user uses the electronic device to perform the 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 between the electronic devices can be performed.
It should be noted that, when the electronic device performs the network video call, the fifth generation mobile communication technology (5 th Generation Mobile Networks, abbreviated as 5G) is adopted, and the electronic device performs the network video call with a suitable bandwidth, i.e. the first BWP. When the electronic device performs network video call in the corresponding BWP, only the corresponding center frequency point and the sampling rate are needed, and each BWP is different in frequency point and bandwidth, and each BWP can be configured correspondingly. For example, the subcarrier spacing, single Side Band (SSB) period, etc. of each BWP may be configured differently to adapt to different service requirements.
In the embodiment of the application, the electronic device can monitor the call fluency of the video call in the network video call process by adopting the first BWP, so as to determine whether the electronic device has the condition of low call fluency such as blurring, screen-display, mosaic and the like in the network video call process.
As a possible implementation manner, the call fluency of the network video call may be determined according to a frame loss rate during the network video call performed by the electronic device using the first BWP.
As another possible implementation manner, the call smoothness of the network video call may also be determined according to the content loss proportion of the single frame picture in the process that the electronic device uses the first BWP to perform the network video call.
As another possible implementation manner, in the process of performing 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 proportion of a single frame picture in the network video call.
It should be noted that, in the present embodiment, the method for detecting the call fluency of the network video call is not limited to the above method, and other possible methods for detecting the call fluency of the network video call are also applicable to the present embodiment, which is not limited in the present embodiment.
When the communication smoothness of the network video communication is detected to not meet the set condition, the electronic device is indicated that the communication effect is better when the electronic device uses the carrier bandwidth of the current communication capacity to perform the network video communication, and the network video communication is continuously performed by adopting the first BWP.
In another possible case, when the electronic device performs the network video call, if it is detected that the call smoothness of the network video call meets the set condition, further, whether the communication state is abnormal is determined to determine whether to switch the bandwidth adopted when 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 call quality of the network video, and when the call fluency is lower than the call fluency threshold, whether the communication state is abnormal is determined.
As a possible implementation manner, when the frame loss rate is used to determine the call smoothness of the network video call in the process that the electronic device uses the first BWP to perform the network video call, when it is determined that the frame loss rate of the video call in the preset duration is greater than the preset frame loss rate, it may be determined that the call smoothness of the network video call meets the set condition.
As another possible implementation manner, when determining the call smoothness of the network video call by using the content loss ratio of the single frame picture in the network video call in the process that the electronic device uses the first BWP to perform the network video call, when determining that the content loss ratio of the single frame picture in the network video call is greater than the preset loss ratio, it may be determined that the call smoothness of the network video call meets the set condition.
As another possible implementation manner, in the process that the electronic device performs the network video call by adopting the first BWP, when determining the call smoothness of the network video call by adopting the frame loss rate of the network video call and the content loss proportion of the single frame picture in the network video call, if determining that the frame loss rate of the network video call is greater than the preset frame loss rate and the content loss proportion of the single frame picture is greater than the preset loss proportion, it may be determined that the call smoothness of the network video call meets the set condition.
In this embodiment, when it is detected that the call smoothness of the network video call performed by the electronic device by using the first BWP meets the set condition, further, the packet loss rate may be determined by counting Real-time transmission (Real-time Transport Protocol, abbreviated as RTP) data packets between the electronic device and the network side, so as to determine whether an abnormality exists in the communication state according to the packet loss rate. The packet loss rate refers to the ratio of the number of lost data packets to the transmitted data set.
104, if the communication state is abnormal, adopting a second BWP to carry out network video call; wherein the communication capacity of the second BWP is larger than the communication capacity of the first BWP.
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 equipment adopts the second BWP to carry out network video call, the improvement of the communication rate and the improvement of the group utilization rate are facilitated.
As a possible case, the network-side device may be a radio network controller (Radio Network Controller, hereinafter abbreviated RNC).
In the embodiment of the application, when real-time transmission data packets are counted, when the packet loss rate is higher than a set packet loss threshold value, the abnormal communication state is determined.
It should be explained that the decrease in the fluency of the network video call may be caused by a network cause or may be caused by a factor at the electronic device side, and therefore, it is necessary to determine the cause of the decrease in the fluency of the network video call by whether the communication state is abnormal.
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 when determining that a second BWP with a communication capacity higher than that of the first BWP exists in the bandwidth allocated by the network side device, the electronic device sends a bandwidth switching request to the network side device. After the network side device receives the switching request sent by the electronic device, when the electronic device receives the switching response sent by the network side device, the bandwidth of the electronic device is switched to a second BWP with the bandwidth higher than that of the first BWP, so that the network video call is carried out by adopting the second BWP. Thus, the communication smoothness of the network video call of the electronic device can be improved by performing the network video call through the second BWP with higher communication capacity.
It should be noted that, in NR (New Radio), the bandwidth of an electronic device for performing a network video call may be dynamically changed, and one carrier bandwidth may be divided into a plurality of BWP, and one electronic device may be configured with a plurality of BWP at the same time, but only one active BWP may be provided 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 communication smoothness of the network video call performed by the first BWP currently adopted by the electronic device cannot meet the user requirement and the communication abnormality exists on the network side, the network side device needs to be requested to switch the BWP with higher communication capacity so as to perform the network video call by adopting the second BWP with higher communication capacity than the first BWP.
According to the network video call method, network video call is conducted by adopting the first carrier bandwidth segment BWP; detecting the communication fluency of network video communication; if the communication fluency meets the set condition, judging whether the communication state is abnormal; if the communication state is abnormal, adopting a second BWP to carry out network video call; wherein the communication capacity of the second BWP is larger than the communication capacity of the first BWP. Therefore, the communication state of the network side is triggered and detected through the communication fluency of the network video call, so that when the communication state of the network side is abnormal, the network side is requested to switch the BWP with higher communication capacity, the network video call can be ensured to be clearer and smoother, and the technical problem that the user visual experience is poor when the network video call quality is poor in the prior art is solved by adjusting the video call parameters, the window size and other modes to improve the network call quality.
On the basis of the above embodiment, after step 104, when the electronic device performs the network video call using the second BWP and detects that the call smoothness of the video call is higher than the call smoothness threshold, the network side device is requested to switch from the second BWP back to the first BWP so as to continue performing the network video call using the first BWP, so as to reduce the power consumption of the electronic device. The following describes the above process in detail with reference to the second embodiment, and fig. 2 is a schematic flow chart of a network video call method provided in the second embodiment of the present application.
As shown in fig. 2, after step 104, the network video call method may further include the steps of:
in step 201, the call fluency of the network video call using the second BWP is detected.
In the embodiment of the present 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 the electronic device has the condition of low call fluency such as blurring, screen-displaying, and mosaic 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 during the network video call performed by the electronic device using the second BWP.
As another possible implementation manner, the call smoothness of the network video call may also be determined according to the content loss proportion of the single frame picture in the process that the electronic device uses the second BWP to perform the network video call.
As another possible implementation manner, in the process of performing the network video call by the electronic device using the second 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 proportion of a single frame picture in the network video call.
It should be noted that, in the present embodiment, the method for detecting the call fluency of the network video call is not limited to the above method, and other possible methods for detecting the call fluency of the network video call are also applicable to the present embodiment, which is not limited in the present embodiment.
In the embodiment of the application, whether the call fluency of the network video call meets the set condition can be judged according to the call fluency of the network video call determined in the process of carrying out the network video call by the electronic equipment by adopting the second BWP. Wherein, the setting condition can be that the call fluency is lower than the call fluency threshold
As a possible implementation manner, when the frame loss rate is used to determine the call smoothness of the network video call in the process that the electronic device uses the second BWP to perform the network video call, it may be determined that the call smoothness of the network video call is higher than the call smoothness threshold when it is determined that the frame loss rate of the video call in the preset duration is less than the preset frame loss rate.
As another possible implementation manner, in the process that the electronic device performs the network video call by using the second BWP, when determining that the call smoothness of the network video call is determined by using the content loss ratio of the single frame picture in the network video call, if determining that the content loss ratio of the single frame picture in the network video call is smaller than the preset loss ratio, it may be determined that the call smoothness of the network video call is higher than the call smoothness threshold.
As another possible implementation manner, in the process that the electronic device performs the network video call by adopting the second BWP, when determining the call smoothness of the network video call by adopting the frame loss rate of the network video call and the content loss proportion of the single frame picture in the network video call, if determining that the frame loss rate of the network video call is smaller than the preset frame loss rate and the content loss proportion of the single frame picture is smaller than the preset loss proportion, determining that the call smoothness of the network video call is higher than the call smoothness threshold.
In the embodiment of the present application, when the electronic device performs the network video call by using the second BWP, it may be determined that the call smoothness when the electronic device switches to the second BWP with higher communication capacity to perform the network video call is improved when it is detected that the call smoothness of the network video call is higher than the call smoothness threshold. 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 this embodiment of the present application, when the electronic device performs a network video call by using the second BWP, when detecting that the call smoothness of the network video call is lower than the call smoothness threshold, further, statistics is performed on real-time transmission RTP data packets between the electronic device and the network side to determine a packet loss rate, and further, whether the communication state is abnormal is determined 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 using the second BWP, when the call fluency of the network video call is determined not to meet the set condition, the network video call is continuously performed by using the first BWP, and when the call fluency of the network video call is determined to meet the set condition, whether the communication state is abnormal is detected. Therefore, when the electronic equipment adopts the second BWP to conduct network video call, and when the call smoothness during the network video call does not meet the user setting condition, the first BWP is adopted to conduct the network video call, so that intelligent BWP switching is realized, network resource allocation is fully utilized, and the power consumption of the electronic equipment is reduced.
