Background

In current Virtual Reality (VR) applications, a server on a network side is generally required to transmit data such as VR pictures to a terminal.

In the related art, a Field of View (FOV) transmission technique is a technique commonly used in VR applications, and performs transmission based on a View picture currently seen by a user. When VR pictures are transmitted by the FOV transmission technique, VR pictures in the direction directly opposite to the current view are encoded by a higher resolution, and VR pictures in other directions are encoded by a lower resolution.

In the FOV transmission scheme, when the view angle of the VR service changes greatly in a short time, the VR terminal needs to download a VR picture stream corresponding to a new view angle from the server, which may result in a large burst data transmission in a short time, and further result in a large data delay, affecting the transmission effect of the VR service.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

It is to be understood that reference herein to "a number" means one or more and "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The current transmission of VR pictures supports two main technical routes: a full-view transmission scheme and a FOV transmission scheme.

The full-view transmission technology refers to that 360-degree surrounding VR pictures are transmitted to a terminal. However, with the full-view transmission scheme, when a viewer watches, only the current view part is actually seen, and the invisible part also occupies the network bandwidth, which causes great waste to network resources.

In view of the disadvantages of the full-view transmission technology in transmission, FOV transmission technology for differentially transmitting VR pictures based on view angles is proposed in the industry. For the FOV transmission technology, there are many different implementation methods and algorithms in the industry at present, and whichever method and algorithm will greatly reduce the requirement for network bandwidth. Currently, there are pyramid projection transmission and Tile-based transmission schemes. Please refer to fig. 1, which illustrates a schematic diagram of a VR frame transmitted based on FOV according to the present disclosure. As shown in fig. 1, a plane right in front of a user viewpoint is an FOV plane, and a VR server encodes a picture in the FOV plane with high resolution; the other four planes are non-FOV planes, and when the VR server encodes pictures in the non-FOV planes, the resolution is gradually reduced from the edge intersected with the FOV plane to the vertex in the opposite direction of the view angle; by the encoding scheme shown in fig. 1, the bandwidth requirement for watching VR pictures can be reduced, and the effective utilization rate of the bandwidth can be improved.

In VR application based on FOV transmission, the VR server is required to provide different VR picture streams at different visual angles, wherein the VR picture stream at a single visual angle only supports rotation within a small range of the visual angle, and if the switched visual angle exceeds a certain range, the VR terminal needs to download the VR picture stream at a new visual angle again.

Please refer to fig. 2, which shows a flowchart of VR frame transmission related to the present disclosure. As shown in fig. 2, in a wireless scenario, the VR frame transmission process is as follows:

1) VR terminal detects that the visual angle rotates.

2) And the VR terminal sends wireless data to the base station, wherein the wireless data comprises the relevant information of the rotation of the visual angle.

3) And the base station receives the wireless data and then processes the wireless data to obtain the relevant information of the rotation of the visual angle.

4) And the base station sends a data packet containing the relevant information of the view angle rotation to the VR server.

5) And the VR server receives the data packet sent by the base station and then performs processing, for example, analyzes the data packet to obtain information related to the rotation of the angle of view, and determines or generates a new VR picture according to the information related to the rotation of the angle of view.

6) And the VR server sends a data packet containing the new VR picture to the base station.

7) And the base station receives the data packet sent by the VR server and then processes the data packet to obtain a new VR picture.

8) The base station transmits wireless data including the new VR screen to the VR terminal.

9) And the VR terminal receives the wireless data and then processes the wireless data to obtain a new VR picture for displaying.

In VR applications, when a user has a large switching angle, the user may feel dizzy if the VR screen is not switched to a new angle in time. In order to ensure the user experience of VR applications, currently, the requirement for the time delay between the view angle rotation and the VR picture reaction in VR applications in the industry is not more than 20 ms.

That is, after the step 1) in fig. 2 is transmitted, from the step 2) to the step 8), the delay between the steps needs to be controlled within 20ms to provide the user with a better VR experience. When the VR terminal detects that the rotation amplitude of the view angle is large and the switched view angle exceeds the rotation range supported by the VR picture stream of a single view angle, it needs to transmit large data in a short time, which requires the base station to transmit large data in step 7), and in order to transmit large data in a short time, the VR terminal needs to occupy large bandwidth, if the VR terminal does not have enough available bandwidth, it will result in large transmission delay and affect the transmission effect of the VR service, and meanwhile, because a large amount of data needs to be transmitted in a short time, in this time, the VR service may occupy the transmission bandwidth already scheduled to other terminals, thereby affecting the wireless transmission effect of other terminals. Similar problems may exist in Augmented Reality (AR) services in wireless scenarios, in addition to VR services. For example, when the AR terminal detects that the viewing angle rotation amplitude is large, the server may be required to send a large amount of new AR data including, but not limited to, text, pictures, audios and videos, and the like to the AR terminal in a short time.

According to the subsequent embodiments of the disclosure, a scheme is provided for switching bandwidth resources for the VR/AR terminal in advance before a visual angle changes to a larger extent in a VR/AR service scene, so that when the VR/AR terminal detects that a large amount of data is transmitted in a short time due to a larger visual angle rotation range, a base station can transmit a VR/AR picture at a new visual angle to the VR/AR terminal in time, and the transmission effect of the VR/AR service is improved.

The base station 320 and the terminal 310 may establish a wireless connection over a wireless air interface. The wireless air interface is based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; alternatively, the wireless air interface may be a wireless air interface based on a 5G next generation mobile communication network technology standard.

Optionally, the wireless communication system may further include a network management device 330.

The plurality of base stations 320 are respectively connected to the network management apparatus 330. The network Management device 330 may be a Core network device in a wireless communication system, for example, the network Management device 330 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC).

To sum up, in the solution shown in the embodiment of the present disclosure, a terminal running a service corresponding to a VR/AR service reports viewing angle rotation information to a base station when a viewing angle rotation angle in a measurement time window exceeds a viewing angle rotation angle threshold, and the base station switches a frequency domain resource used by the terminal from a first frequency domain resource to a second frequency domain resource after receiving the viewing angle rotation information, because when running the service corresponding to the VR/AR service, if the viewing angle rotation angle of the terminal in a certain time period (i.e., the measurement time window) is large, it indicates that the terminal has a large probability that a VR/AR picture under a new viewing angle needs to be acquired from a server, and a large data transmission may be generated in a short time, at this time, before the large data transmission comes, the base station may switch the frequency domain resource used by the terminal in advance, so that when the large data transmission comes in a short time, the terminal has larger bandwidth available, thereby reducing the time delay of the VR/AR picture transmission of large data volume in short time and improving the transmission effect of the VR/AR service.

In step 502, when the viewing angle rotation angle exceeds the viewing angle rotation angle threshold, reporting viewing angle rotation information to the base station, where the viewing angle rotation information is used to instruct the base station to switch the frequency domain resource used by the terminal from the first frequency domain resource to the second frequency domain resource.

and/or the presence of a gas in the gas,

Optionally, before obtaining the view rotation angle of the specified service in the measurement time window, the method further includes:

Optionally, the method further includes:

Optionally, when the angle of rotation of the view exceeds the threshold of the angle of rotation of the view, reporting the angle of rotation of the view to the base station, including:

the second timer is started when the terminal reports the view rotation information for the last time, and the timing duration is the report prohibition duration.

Fig. 6 is a flowchart illustrating a resource switching method according to an exemplary embodiment, where the resource switching method may be performed by a terminal and a base station in an interaction manner, for example, the terminal may be the terminal 310 in the implementation environment shown in fig. 3, and the base station may be the base station 320 of the terminal in the implementation environment shown in fig. 3. As shown in fig. 6, the method may include the following steps.

In step 601, the base station issues a measurement configuration to the terminal, and the terminal receives the measurement configuration issued by the base station; the measurement configuration includes measuring the duration of a time window and a threshold of a viewing angle rotation angle.

In this embodiment of the present disclosure, the terminal may be a terminal running a service corresponding to a specific service, where the specific service may be a VR service or an AR service.

For example, the terminal may be a terminal running a VR/AR application, and the VR/AR application needs to perform data interaction with the cloud server.

Optionally, the base station may issue the measurement configuration to the terminal through a reconfiguration message.

In a possible implementation manner, the base station may issue the measurement configuration to the terminal when the terminal starts a specific service, that is, the VR/AR service.

For example, when the terminal starts the VR/AR service, the terminal may report the service information of the VR/AR service to the base station, and after receiving the service information reported by the terminal, the base station may confirm that the terminal starts the VR/AR service, and at this time, the base station may issue measurement configuration to the terminal.

In another possible implementation manner, the base station may also issue the measurement configuration for the terminal when the terminal accesses the base station.

For example, when accessing a base station, a terminal supporting a VR/AR service may report service information of the VR/AR service supported by the terminal to the base station, and after acquiring the service information reported by the terminal, the base station may issue the measurement configuration for the terminal, and the terminal receives the measurement configuration and stores the measurement configuration locally. When starting the VR/AR service, the subsequent terminal can directly read the measurement configuration stored locally without reporting the service information again.

In the embodiment of the present disclosure, the configuration information issued by the base station for different terminals may be different, or for the same terminal, the base station may also issue different configuration information under different VR/AR services.

Optionally, before issuing the measurement configuration to the terminal, the base station may obtain service information of the specified service; when the measurement configuration is issued to the terminal, the base station may issue the measurement configuration to the terminal according to the service information.

Optionally, the service information may include at least one of a resolution of the specified service in the terminal and a coding mode of the specified service.

Optionally, the Service information may also include other information of the specified Service, such as Quality of Service (QoS) requirements, delay requirements, and the like of the VR/AR Service.

In a possible implementation manner, if the service information is service information reported by the terminal when the terminal starts the VR/AR service, the base station may issue measurement configuration for the terminal according to the service information of the VR/AR service started by the terminal this time, where parameters in the measurement configuration are related to content carried in the service information, for example, when resolution carried in the service information is low, the base station may configure a longer measurement time window or a higher angle-of-view rotation threshold.

In another possible implementation manner, if the service information is service information reported when the terminal accesses the base station, the base station may issue corresponding measurement configurations for various VR/AR services supported by the terminal according to the service information of the various VR/AR services supported by the terminal, and the terminal may obtain a measurement configuration corresponding to a current VR/AR service, which is configured in advance, from a local location when starting a certain VR/AR service.

For example, when the measurement configuration is a measurement configuration issued by the base station according to service information reported when the terminal starts the VR/AR service, the measurement configuration may include the measurement starting instruction, and after receiving the measurement starting instruction, the terminal may perform the subsequent step 602.

In another possible implementation manner, when the measurement configuration is a measurement configuration issued by the base station according to the service information reported by the terminal during access, the terminal may directly obtain the corresponding measurement configuration from the local and start to execute step 602 when the terminal subsequently starts the VR/AR service.

In addition, in order to avoid the waste of signaling resources caused by frequent reporting of the terminal under the condition of large visual angle change, the measurement configuration also comprises a report prohibition duration for controlling a report interval of the terminal.

In step 602, when the terminal runs a service corresponding to the specified service, the view angle rotation angle in the measurement time window is obtained.

In the embodiment of the disclosure, when the terminal runs the service corresponding to the VR/AR service, if the measurement configuration is already obtained, the angle of rotation of the terminal in the measurement time window may be obtained.

For example, the terminal may periodically acquire the view angle rotation angle in the measurement time window at certain time intervals, and start and stop times of the measurement time window corresponding to the view angle rotation angle acquired each time are different.

For example, taking the length of the measurement time window as 5ms as an example, the terminal acquires the view angle rotation angle within the measurement time window every 1ms, and the start time of the measurement time window when the view angle rotation angle is acquired twice in the adjacent time is 1ms apart.

For example, assume that the terminal receives the measurement configuration at 10ms and acquires the view angle rotation angle within the measurement time window for the first time at 11ms, which is a measurement time window having a duration of 5ms from 7ms to 11 ms; after that, the terminal acquires the view angle rotation angle within the measurement time window for the first time at 12ms, which is a measurement time window having a duration of 5ms from 8ms to 12ms, and so on.

In step 603, when the viewing angle rotation angle exceeds the viewing angle rotation angle threshold, the terminal reports the viewing angle rotation information to the base station; correspondingly, the base station receives the view angle rotation information reported by the terminal.

And when the terminal acquires the visual angle rotating angle in one measuring time window every time, comparing the visual angle rotating angle with a visual angle rotating angle threshold in the measuring configuration, and if the visual angle rotating angle exceeds the visual angle rotating angle threshold, reporting the visual angle rotating information to the base station by the terminal.

Optionally, the terminal may report the view rotation information through a measurement report message.

Optionally, the view rotation information includes a view rotation angle of the terminal within a measurement time window.

Optionally, when the measurement configuration includes a report prohibition duration and the terminal reports the view angle rotation information to the base station, the terminal may start the first timer at the same time, and the timing duration of the first timer is the report prohibition duration. In the running process of the first timer, if the terminal measures that the visual angle rotating angle in the new measuring time window exceeds the visual angle rotating angle threshold again, the terminal cannot report the visual angle rotating information again until the running of the first timer is finished, so that the repeated reporting of the visual angle rotating information is reduced, and the waste of signaling resources is avoided.

Correspondingly, when the visual angle rotation angle exceeds the visual angle rotation angle threshold and a second timer is not operated in the terminal, reporting the visual angle rotation information to the base station; the second timer is started when the terminal reports the view rotation information for the last time, and the timing duration is the report prohibition duration.

When the terminal measures that the visual angle rotation angle in the measurement time window exceeds the visual angle rotation angle threshold at a certain time, whether a second timer started when the previous visual angle rotation information is reported runs or not can be checked, if the second timer running currently runs, the fact that the interval between the current time and the last time of reporting the visual angle rotation information does not reach the report prohibition time length is shown, at this time, the terminal cannot report the visual angle rotation information at this time, otherwise, if the second timer running currently does not exist, the fact that the terminal has not reported the visual angle rotation information before is shown, or the interval between the current time and the last time of reporting the visual angle rotation information exceeds the report prohibition time length is shown, at this time, the terminal can report the visual angle rotation information.

In step 604, the base station switches the frequency domain resources used by the terminal from the first frequency domain resources to the second frequency domain resources.

Wherein the load of the first frequency domain resource is greater than the load of the second frequency domain resource;
