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 application.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. The objects distinguished by "first", "second", and the like are usually a class, and the number of the objects is not limited, and for example, the first object may be one or a plurality of objects. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The method for video call provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 1, an embodiment of the present application provides a method for video call, including:
Under different wireless access technologies, the uplink bandwidth of the network and the video quality requirements of the operator network on video calls are different, for example: the uplink bandwidth of a 4G Long Term Evolution (LTE) network is 10Mbps (the highest theoretical value), and the uplink bandwidth of a 5G New air interface (New Radio, NR) network is 100Mbps (the highest theoretical value); LTE Voice bearers (Voice over LTE, VoLTE) require level 3.0(960kbps, 480 × 640, 30fps), NR Voice bearers (Voice over NR, volr) require level3.1(2Mbps, 720 × 1280, 30fps) or even higher.
In this embodiment, when a first electronic device initiates a video call service, the first electronic device that needs to call needs to first determine a video quality parameter during the video call, for example: resolution, code rate, frame rate, etc. The first electronic device matches the video quality parameters suitable for the current RAT according to its registered RAT (i.e. the currently accessed RAT).
And 102, carrying out video call service according to the video quality parameters.
And after determining the video quality parameter matched with the target RAT currently registered by the first electronic equipment, transmitting video data according to the video quality parameter. When the video call service is performed, the video quality parameter matched with the target RAT registered by the current electronic device can be used, so that the bandwidth of the currently registered target RAT can meet the current video transmission rate, and the video quality of the video call performed by a plurality of electronic devices in the same serving cell at the same time can be ensured.
When the video call service is performed according to the video quality parameters, the video quality parameters determined by a first electronic device establishing a video call can be used for video data transmission, and the video quality parameters determined by a second electronic device establishing a video call with the first electronic device can also be used for video data transmission. Specifically, the first electronic device may negotiate with the second electronic device to determine the finally used video quality parameter.
According to the embodiment of the application, the video quality parameters suitable for the current RAT are matched according to the RAT currently accessed by the electronic equipment instead of the highest-level video quality parameters supported by the current electronic equipment, so that the problem of image abnormity caused by insufficient bandwidth when multiple devices in the same network service cell simultaneously carry out video call can be avoided, the user experience is enhanced, and network resources are saved.
Optionally, the step 101 includes: and under the condition that the first electronic equipment initiates a video call service, determining a first-level video quality parameter corresponding to the target RAT.
In this embodiment, the target RAT registered by the first electronic device may correspond to different levels of video quality parameters. For example: the first-level video quality parameter corresponding to the target RAT is a highest-level quality parameter, and if the first electronic device is registered in RAT F (for example, 5G), the first-level video quality parameter is level F, and the second-level video quality parameter is level E. Under the high uplink bandwidth (such as 5G uplink 100Mbps) of the RAT F (such as 5G), the pressure for simultaneously transmitting the level F video by a plurality of electronic devices in the same cell is avoided, so that the video quality problem is not easy to occur; it should be noted that the electronic device is simultaneously compatible with a lower level of image quality level E (for example, level 3.0), level D, and the like.
If the first electronic device is registered in RAT E (for example, 4G), the first-level video quality parameter corresponding to RAT E is level E, and the second-level video quality parameter is level D. Under the uplink bandwidth of the RAT E (for example, 10Mbps on a 4G line), the simultaneous transmission of level E (level 3.0, 960kbps, 480P, 30fps) videos by a plurality of electronic devices in the same cell has no pressure, and the video quality problem is not easy to occur.
In the embodiment, the video call service is performed by using the first-level video quality parameter (i.e., the highest-level video quality parameter) corresponding to the currently registered RAT, so that the current video transmission rate can be met, and the video quality of the video call performed by multiple electronic devices in the same serving cell at the same time can be ensured.
Specifically, the determining a first level video quality parameter corresponding to the target RAT includes: acquiring a mapping relation between the RAT and video quality parameters of different levels; and determining a first-grade video quality parameter corresponding to the target RAT according to the mapping relation.
The correspondence between the RAT registered by the electronic device and the video quality parameter may be stored in the electronic device, for example: the electronic device stores an RAT-level mapping table, where the mapping table is shown in fig. 2, level F is a highest-level video quality parameter (i.e., the first-level video quality parameter) supported by the electronic device, and when the electronic device is registered in the RAT F, the bandwidth is high, so that even if the highest-level video quality parameter level F is used, video transmission data loss is not easy to occur; similarly, the level E is not easy to lose video transmission data under the bandwidth of the RAT E; level F is more suitable for RAT F network, level E is more suitable for RAT E. It should be noted that RATs are downward compatible with Level, i.e., Level E is also suitable for RAT F (but not optimal).
Optionally, the method further comprises: when the first-level video quality parameters are utilized to carry out video call service, the transmission quality of video data is detected; the step 101 further comprises: determining a second-level video quality parameter corresponding to the target RAT under the condition that the transmission quality parameter value of the video data does not meet a preset quality threshold; wherein the second level video quality parameter has a level lower than the level of the first level video quality parameter.
The transmission quality parameters of the video data may be: transmission rate, bit error rate, block error rate, etc. In this embodiment, when selecting the video quality parameter, the highest-level video quality parameter corresponding to the RAT currently registered by the electronic device is preferentially selected. If a video call service is performed by using the highest-level video quality parameter, a video data transmission fault occurs, such as: when a network problem occurs in the video process, which results in the loss of video data packets, the electronic device adjusts the video quality parameters of adjacent low-level video data to adapt to the change of the network and maintain the stability of video data transmission.
When the video call service is performed by using the highest-level video quality parameter, if it is detected that the parameter value of the transmission quality of the video data does not satisfy the preset quality threshold, for example: and if the parameters such as the error rate, the block error rate and the like do not meet the video call requirement, adjusting to the second-level video quality parameter to carry out the video call. The quality threshold of the transmission quality of the video data can be set according to the requirement on the video image. For example: when the electronic equipment is registered in the RAT F, the level F is the highest-level video quality parameter matched with the RAT F, namely the first-level video quality parameter, and the level E is the second-level video quality parameter matched with the RAT F, and when the video quality parameter of the level F is used for carrying out video call, if the transmission quality of video data does not meet the condition of a preset threshold, the video quality parameter of the level E is adjusted to be used for carrying out the video call.
In the video call process of the embodiment, the network resources may change at any time, and if the network becomes poor, the electronic device may negotiate a level with lower image quality to perform video transmission, thereby avoiding image abnormality caused by data loss.
Optionally, the step 102 includes: performing video quality parameter negotiation with a second electronic device to be subjected to the video call service, and determining a target video quality parameter used by the video call service; after the negotiation is finished, establishing a video call with the second electronic equipment; and transmitting video data with the second electronic equipment by using the target video quality parameter.
When the first electronic equipment and the second electronic equipment establish the video call, the video quality parameter negotiation is completed before the call is established, so that the electronic equipment of the two parties can use the video quality parameters of the same grade to carry out the video call. For example: when the first electronic device is registered in an RAT F (such as 5G), selecting a level F video parameter for negotiation, and performing video data transmission by using the level F video parameter index by default after the video is connected; when the first electronic device is registered in RAT E (for example, 4G), even if the first electronic device supports level F at the highest level, the first electronic device may select a video quality parameter of level E (a highest-level video quality parameter suitable for RAT E) to perform negotiation, and perform video data transmission using a video quality parameter index that is a default video level E after the negotiation is completed.
When video quality parameter negotiation is carried out, the first electronic device and the second electronic device which need video call mutually inform the video quality parameters which are determined according to the currently registered RAT, and the video quality parameters which can meet the video call quality requirements of the two parties are selected as the target video quality parameters through negotiation. For example: the first electronic equipment determines that the first-grade video quality parameter is the highest-grade quality parameter, and the video quality (image quality, transmission rate and other requirements) required by the first electronic equipment can be met; and the second electronic equipment determines that the second-level video quality parameter is the highest-level quality parameter supported by the second-level video quality parameter, the video quality required by the second electronic equipment can be met, and in order to ensure the video call quality of both sides, the second-level video quality parameter can be selected as the target video quality parameter. Or, if the highest-level quality parameters supported by the first electronic device and the second electronic device are both the first-level video quality parameters, the first-level video quality parameters may be used as the target video quality parameters.
When the video call is just established, the negotiated video parameters before the call establishment are used for the call, the bandwidth of the current registered RAT is enough to meet the current video transmission rate, and the video quality of the video call of a plurality of electronic devices in the same service cell can be guaranteed. After a video call is established, network resources may also change at any time, if the network becomes poor, no matter which RAT is currently registered, which level of video quality parameter is used, and a network problem occurs in the video process to cause loss of a video data packet (affect video quality), the electronic device adjusts to the low-level video quality parameter to adapt to the change of the network, maintain the stability of video data transmission, and avoid image abnormality caused by data loss.
The following describes a video call method according to the present application by using a specific embodiment, as shown in fig. 3:
the method comprises the following steps: the electronic equipment initiates a video call service;
step two: the electronic device queries an RAT-level mapping table according to a currently registered RAT, selects an appropriate video quality parameter, and performs media negotiation such as SDP (Session Description Protocol) negotiation when a user video call is established;
step three: and negotiating video quality parameters and establishing a video call. When a video call is just established, the negotiated video parameters before call establishment are basically used, and the highest-level video quality parameters matched with the currently registered RAT are selected, so that the bandwidth of the currently registered RAT is generally enough to meet the current video transmission rate, and the video quality of video calls simultaneously performed by a plurality of terminals in the same service cell can be ensured.
According to the embodiment of the application, the video quality parameters suitable for the current RAT are matched according to the RAT currently accessed by the electronic equipment instead of the highest-level video quality parameters supported by the current electronic equipment, so that the problem of image abnormity caused by insufficient bandwidth when multiple devices in the same network service cell simultaneously carry out video call can be avoided, the user experience is enhanced, and network resources are saved.
