Among the related technologies, the field of view (FOV) transmission technology is commonly used in VR applications, and is a technology for transmission based on the viewing angle picture currently seen by the user.

Detailed ways

The exemplary embodiments will be described in detail here, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

It should be understood that the "several" mentioned in this article refers to one or more, and the "plurality" refers to two or more. "And/or" describes the association relationship of the associated objects, indicating that there can be three types of relationships, for example, A and/or B, which can mean: A alone exists, A and B exist at the same time, and B exists alone. The character "/" generally indicates that the associated objects before and after are in an "or" relationship.

Currently, the transmission of VR images supports two main technical routes: full-view transmission scheme and FOV transmission scheme.

The full-view transmission technology refers to the transmission of all 360-degree surround VR images to the terminal. However, with the full-view transmission scheme, the viewer actually only sees the current field of view when watching, and the invisible part also occupies the network bandwidth, which causes a relatively large waste of network resources.

In view of the shortcomings of the full-view transmission technology in terms of transmission, the industry has proposed a FOV transmission technology for differentially transmitting VR images based on the viewing angle. For FOV transmission technology, there are many different implementation methods and algorithms in the industry. No matter which method or algorithm, it will greatly reduce the demand for network bandwidth. At present, there are pyramid projection transmission and Tile-based transmission schemes. Please refer to FIG. 1, which shows a schematic diagram of a VR image based on FOV transmission related to the present disclosure. As shown in Figure 1, the plane directly in front of the user's point of view is the FOV plane, and the VR server uses high resolution to encode the pictures in the FOV plane; the remaining four planes are non-FOV planes, and the VR server encodes the pictures in the non-FOV plane. At this time, the resolution gradually decreases from the edge that intersects the FOV plane to the vertex in the opposite direction of the viewing angle; through the coding scheme shown in Figure 1, the bandwidth requirement for viewing VR images can be reduced and the effective utilization of bandwidth can be improved.

In VR applications based on FOV transmission, the VR server needs to provide different VR image streams under different viewing angles. Among them, the VR image stream of a single angle of view only supports rotation within a small range of angles. If the switched angle of view exceeds a certain range, the VR terminal will You need to re-download the VR screen stream under the new perspective.

Please refer to FIG. 2, which shows a flow chart of VR picture transmission related to the present disclosure. As shown in Figure 2, in a wireless scenario, the VR picture transmission process is as follows:

1) The VR terminal detects that the viewing angle is rotated.

2) The VR terminal sends wireless data to the base station, and the wireless data contains information about viewing angle rotation.

3) The base station processes the wireless data after receiving the wireless data, and obtains the related information of the viewing angle rotation.

4) The base station sends the VR server a data packet containing information related to the viewing angle rotation.

5) After the VR server receives the data packet sent by the base station, it processes it, for example, parses the data packet to obtain information related to the viewing angle rotation, and determines or generates a new VR image according to the related information of the viewing angle rotation.

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

7) After the base station receives the data packet sent by the VR server, it processes it to obtain a new VR picture.

8) The base station sends wireless data containing the new VR screen to the VR terminal.

9) After the VR terminal receives the wireless data, it processes it to obtain a new VR screen and display it.

In VR applications, when a user has a large perspective switch, if the VR screen does not switch to a new perspective in time, the user is likely to feel dizzy. In order to ensure the user experience of VR applications, the industry currently requires that the time delay between the viewing angle rotation in VR applications and the response of the VR picture is not more than 20ms.

That is to say, after the step 1) shown in Figure 2 above is sent, from step 2) to the end of step 8), the delay between these needs to be controlled within 20ms in order to provide users with better VR Experience. Among them, when the VR terminal detects that the angle of view rotation is large, and the switched angle of view exceeds the rotation range supported by the VR screen stream of a single angle of view, a large amount of data needs to be transmitted in a short time, which requires the base station to perform step 7) in a short time To transmit large amounts of data, and in order to transmit large amounts of data in a short time, the VR terminal needs to occupy a large bandwidth. If the VR terminal does not have enough available bandwidth at this time, it will cause a large transmission delay and affect the VR service At the same time, due to the need to transmit a large amount of data in a short time, during this time, the VR service may occupy the transmission bandwidth that has been scheduled to other terminals, thereby affecting the wireless transmission effect of other terminals. In addition to VR services, similar problems also exist in Augmented Reality (AR) services in wireless scenarios. For example, when the AR terminal detects that the angle of view rotation is large, the server may need to send a large amount of new AR data to the AR terminal in a short time, including but not limited to text, pictures, audio and video, and so on.

Subsequent embodiments of the present disclosure provide a solution for switching bandwidth resources for the VR/AR terminal in advance in the VR/AR business scenario before the viewing angle changes significantly, so that the VR/AR terminal detects the viewing angle rotation When the amplitude is large and a large amount of data is transmitted in a short period of time, the base station can transmit the VR/AR screen under the new perspective to the VR/AR terminal in time to improve the transmission effect of the VR/AR service.

The viewing angle rotation angle in the measurement time window) is larger, which means that the terminal has a high probability of obtaining the VR/AR picture under the new viewing angle from the server, which may cause large data transmission in a short time. At this time, the base station It is possible to switch the frequency domain resources used by the terminal in advance before the arrival of large data transmission, so that when large data transmission arrives in a short time, the terminal has a large bandwidth available, thereby reducing the large amount of data in a short time.

Wherein, the second timer is started when the terminal reports the viewing angle rotation information last time, and the timing duration is the timer for the duration of the reporting prohibition.

Fig. 6 is a flow chart showing a resource switching method according to an exemplary embodiment. The resource switching method may be executed interactively by a terminal and a base station. For example, the terminal may be the terminal 310 in the implementation environment shown in Fig. 3, and the base station It may be the base station 320 of the terminal in the implementation environment shown in FIG. 3. As shown in Figure 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 the length of the measurement time window and the viewing angle rotation angle threshold.

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

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

Optionally, the base station can deliver the measurement configuration to the terminal through a reconfiguration message.

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

For example, when the terminal starts the VR/AR service, it can report the service information of the VR/AR service to the base station. After the base station receives the service information reported by the terminal, it can confirm that the terminal has started the VR/AR service. At this time, the base station can Deliver the measurement configuration to the terminal.

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

For example, when a terminal supporting VR/AR services accesses a base station, it can report the service information of the VR/AR service it supports to the base station. After the base station obtains the service information reported by the terminal, it can issue the above measurement configuration for the terminal. The terminal receives the measurement configuration and stores it locally. When the subsequent terminal starts the VR/AR service, it does not need to report the service information again, and can directly read the locally stored measurement configuration.

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

Optionally, before sending the measurement configuration to the terminal, the base station may obtain the service information of the specified service; when sending the measurement configuration 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 the resolution corresponding to the designated service in the terminal, and the coding mode of the designated service.

Optionally, the service information may also include other information about the specified service, for example, the quality of service (QoS) requirements and delay requirements of the VR/AR service.

In a possible implementation, if the above service information is the service information reported by the terminal when the VR/AR service is started, the base station can issue measurements for the terminal according to the service information of the VR/AR service started this time by the terminal Configuration. The parameters in the measurement configuration are related to the content carried in the service information. For example, when the resolution carried in the service information is low, the base station can configure a longer measurement time window or a higher viewing angle rotation angle threshold.

In another possible implementation manner, if the above service information is the service information reported when the terminal accesses the base station, the base station can, according to the service information of the various VR/AR services supported by the terminal, be the various VR/AR services supported by the terminal. The AR service delivers the corresponding measurement configuration. When the terminal starts a certain VR/AR service, it can obtain the pre-configured measurement configuration corresponding to the current VR/AR service from the local.

For example, when the above-mentioned measurement configuration is a measurement configuration issued by the base station according to the service information reported by the terminal when the VR/AR service is started, the measurement configuration may include the above-mentioned measurement start instruction. After the terminal receives the measurement start instruction, that is, The subsequent step 602 can be performed.

In another possible implementation, when the above-mentioned measurement configuration is a measurement configuration issued by the base station according to the service information reported by the terminal during access, the terminal can directly obtain the corresponding locally when it subsequently starts the VR/AR service. Measure the configuration and start step 602.

In addition, in order to avoid a waste of signaling resources caused by frequent reporting by the terminal in the case of a large view angle change, the foregoing measurement configuration also includes a reporting prohibition period for controlling the reporting interval of the terminal.

In step 602, when the terminal runs the service corresponding to the specified service, the viewing angle rotation angle within the measurement time window is acquired.

In the embodiment of the present disclosure, when the terminal is running the service corresponding to the VR/AR service, if the measurement configuration has been obtained, the viewing angle rotation angle of the terminal within the measurement time window can be obtained.

For example, the terminal may periodically obtain the viewing angle rotation angle within the measurement time window at a certain time interval, and the start and end times of the measurement time window corresponding to the viewing angle rotation angle acquired each time are different.

For example, taking the length of the measurement time window of 5 ms as an example, the terminal obtains the viewing angle rotation angle within the measurement time window every 1 ms, and the start time of the measurement time window when obtaining the viewing angle rotation angle twice is separated by 1 ms.

For example, suppose that the terminal receives the measurement configuration at the 10th ms, and acquires the viewing angle rotation angle in the measurement time window for the first time at the 11th ms. The measurement time window acquired for the first time is the duration from the 7th ms to the 11th ms. The measurement time window is 5ms; after that, the terminal obtains the viewing angle rotation angle in the measurement time window for the first time at the 12th ms. The measurement time window obtained for the first time is 5ms from the 8th to the 12th ms. The measurement time window, 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 viewing angle rotation information reported by the terminal.

Each time the terminal obtains a viewing angle rotation angle within a measurement time window, it compares the viewing angle rotation angle with the viewing angle rotation angle threshold in the measurement configuration. If the viewing angle rotation angle exceeds the viewing angle rotation angle threshold, the terminal reports the viewing angle to the base station Turn information.

Optionally, the terminal may report the above-mentioned viewing angle rotation information through a measurement report message.

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

Optionally, when the aforementioned measurement configuration includes the reporting prohibition time length, when the terminal reports the viewing angle rotation information to the base station, the first timer may be started at the same time, and the timing duration of the first timer is the reporting prohibition time length. During the operation of the first timer, if the terminal again measures that the viewing angle rotation angle in the new measurement time window exceeds the viewing angle rotation angle threshold, the terminal will no longer report the viewing angle rotation information until the end of the first timer. Thereby, repeated reporting of viewing angle rotation information is reduced, and the waste of signaling resources is avoided.

Correspondingly, when the viewing angle rotation angle exceeds the viewing angle rotation angle threshold, and a second timer is not running in the terminal, the viewing angle rotation information is reported to the base station; wherein, the second timer is the last time the terminal reported viewing angle rotation Started when the message is sent, and the timing duration is the timer for which the reporting duration is prohibited.

Among them, when the terminal measures that the viewing angle rotation angle in the measurement time window exceeds the viewing angle rotation angle threshold at a certain time, it can first check whether there is a second timer that was started when the viewing angle rotation information was reported previously. If there is a running second timer It means that the interval between the current time and the time when the viewing angle rotation information was reported last time has not reached the reporting prohibition period. At this time, the terminal will not report the viewing angle rotation information this time. On the contrary, if there is no second timer running locally This means that the terminal has not reported viewing angle rotation information before, or the interval between the current time and the time when the viewing angle rotation information was reported last time has exceeded the reporting prohibition period. At this time, the terminal can report the viewing angle rotation information.

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

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

And/or, the number of carriers of the first frequency domain resource is less than the number of carriers of the second frequency domain resource.

In the embodiments of the present disclosure, after the base station receives the viewing angle rotation information reported by the terminal, it can confirm that a large data volume burst transmission will occur. At this time, the base station can switch the terminal to a lighter load based on the load conditions of each frequency band. Frequency band; Or, the base station can also increase the number of carriers that can be used by the terminal; Or, the base station can also switch the terminal to a complex and lighter frequency band while increasing the number of carriers that can be used by the terminal.

Optionally, when the viewing angle rotation information includes the viewing angle rotation angle of the terminal in the measurement time window; the base station may also switch the frequency domain resource used by the terminal from the first frequency domain resource to the second frequency domain resource according to the viewing angle rotation angle. Frequency domain resources.

For example, when the viewing angle rotation angle is small, the base station can switch the terminal to a lighter-loaded frequency band, and/or add a small number of carriers for the terminal; and when the viewing angle rotation angle is large, the base station can switch the terminal to a more loaded frequency band. Lighter frequency bands, and/or, increase the number of carriers for the terminal.
