The present application is filed on the basis of a Chinese patent application filed on Jan.

Technical field

The present application relates to a wireless communication technology, and in particular, to a virtual reality service processing method, a radio access network element device, and a storage medium.

Background technique

Existing virtual reality (VR)/Augmented Reality (AR) transmissions are demanding on the network, especially interactive (immersive) VR applications need to meet the requirements of "low latency, high bandwidth". For example, 4K resolution video playback requires 25Mbps bandwidth, single-eye 8K resolution 3D panoramic video playback requires 5Gbps bandwidth, and immersive VR has strict requirements for delay (MTP-Motion to Photon, 3D due to user's viewing angle change) The scene switching delay is less than 20ms).

In the VR application scenario, 3D scene switching due to changes in the user's perspective is involved. The technologies involved include a full view transmission scheme and a field of view (FoV) transmission scheme. In the display system, FoV is the angle between the edge of the display and the point of view (eye).

In the full-view transmission scheme, 360-degree surrounding pictures are transmitted to the terminal, and all processing is done locally at the terminal, the code rate is 5-10 times that of ordinary plane video, and the monocular 8K panoramic video requires bandwidth of 5G. The bandwidth requirements are higher, the delay requirements are lower, and the "maintenance of bandwidth" can directly utilize existing mainstream video transmission technologies such as MPEG, DASH, HAS, HLS, and HPD.

In the FoV transmission scheme, the corresponding frame data is constructed according to the user's perspective posture. One frame of data only contains partial visual information equal to or larger than the angle of view, and the terminal determines the posture position of the user's perspective, and sends the interactive signal to the cloud. Request corresponding frame data, including terminal processing delay, network transmission delay, and cloud processing delay. The bandwidth requirement is reduced, the delay requirement is higher, and the "time delay is used for bandwidth". For example, Facebook's FoV transmission scheme based on pyramid projection can reduce the average bit rate of media files to 20% of the original image quality of ERP projection. Sacrifice part of the image quality experience to reduce the need for MTP 20ms interaction. The pre-generated corresponding 30 cone full-view files are stored on the server (storage delay).

Since FoV can reduce the demand for the network, the FoV transmission scheme is currently a hot spot. Taking FoV-based transmission as an example, as shown in Figure 1, when the perspective FoV changes, if the perspective FoV changes, the threshold does not exceed the threshold. There is no need to retransmit the FoV data; if the angle of view FoV changes beyond the threshold and affects the VR resolution, the new FoV data needs to be retransmitted. Therefore, a large pulse-type traffic transmission may occur, which may cause great impact on the network. The impact.

However, in the related art, there is no effective solution to the above problem.
