The embodiment of the disclosure provides a media stream service quality policy control method, which can be applied to an application environment as shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The data storage system may store data that the server 104 needs to process. The data storage system may be integrated on the server 104 or may be located on a cloud or other network server.

In one embodiment, as shown in fig. 2, a method for controlling a policy of service quality of a media stream is provided, and the method is applied to the server 104 in fig. 1 for illustration, and includes the following steps:

step S202, a strategy request of media stream service quality sent by a gateway is received, wherein the strategy request comprises a strategy identifier of the service quality, a media type and media content parameters determined by the gateway according to the media type contained in the media stream, and the strategy identifier corresponds to a preset initial strategy scheme of the media stream service quality.

The media stream is a streaming technology, so that streaming media can be played on a network, and may include various types of audio streams, video streams, touch streams, kinesthesia streams, and the like. The transmission bandwidth, transmission delay and jitter rate required by different media streams are different, and the required service quality is also different, so that the strategy request of the corresponding media stream service quality can be formulated according to the type of the media stream, and the transmission quality is improved.

Fig. 3 is a schematic diagram of a media stream service quality policy control method in an embodiment, which may include a media gateway, a dynamic policy engine, and a network awareness engine. The application end or some intermediate processing node sends the media stream to the media gateway, and the media gateway can confirm the policy request of the service quality of the media stream according to the type of the media stream, wherein the policy request can include the policy identifier of the service quality, the media type and the media content parameters. Wherein the policy identification is determined based on the media stream, e.g. the policy identification is a multi-bit binary value, wherein a value of 1 on a bit represents a specified media stream, e.g. 0001 is an audio stream, 0011 is an audio stream + video stream, 0100 is a haptic stream. The media types may include audio streams, video streams, haptic streams, kinesthetic streams, and the like. The media content parameters may include the size of the media stream, the code rate, etc.

The dynamic policy engine may generate a query request for the media processing node for querying a resource state of the media processing node according to the policy request. When multiple media streams are transmitted simultaneously, the service quality of the media streams may be affected due to occupation of the nodes, and the resource status of the media processing nodes needs to be queried. The resource status of a node may include node in use, node available, node busy, node offline, etc. The dynamic policy engine supports distributed deployment and can have multiple query interfaces with the network awareness engine.

According to the strategy identification in the strategy request, the initial strategy scheme of the preset media stream service quality is obtained, and the inquired resource state, media type and media content parameters of the media processing node are updated to the initial quality strategy scheme, so that the adjusted strategy scheme can be obtained.

Step S208, responding to the strategy request, and returning the strategy identification corresponding to the strategy scheme after adjustment to the gateway so as to instruct the gateway to send the media stream to a target media processing node for processing according to the strategy scheme after dynamic adjustment.

The policy identifier corresponds to the policy scheme, the adjusted policy scheme comprises a policy identifier, a node address, a service quality parameter and the like, the policy identifier can be returned to the gateway, the gateway can acquire the latest node address according to the policy identifier, and the media stream is sent to the target media processing node for processing.

The resource duty cycle of the node may be queried by the media processing node address, the resource duty cycle may be compared to a quality of service control parameter, and the target media processing node may be one or more depending on whether the node is busy or not. The adjusted policy scheme may include an address and a quality of service control parameter of a target media processing node that processes the media stream corresponding to the policy request, the media stream may be sent to the target media processing node for processing, the target media processing node obtains a corresponding policy scheme according to the policy identifier, and the quality of service control parameter in the adjusted policy scheme corresponding to the policy identifier may be invoked to process the media stream.

In some embodiments of the disclosure, the querying the resource state of the media processing node based on the query request includes:

After the network perception engine acquires the query request, the resource state of the media processing node can be refreshed, namely the latest node resource state is acquired, and whether the node is idle or busy is judged.

In some embodiments of the disclosure, the policy identification in the policy request includes a policy identification determined by the gateway based on a media type contained in the media stream and/or whether there is a specified type of sensitive data in the media stream;
