[0059] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0060] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the present application are all information and data authorized by the user or authorized by all parties.

[0061] The embodiments of the present disclosure provide a media stream quality of service policy control method, which can be applied to an application environment as shown in Figure 1 . The terminal 102 communicates with the server 104 through the network. The data storage system can store the data required to be processed by the server 104. The data storage system can be integrated on the server 104, or placed on the cloud or other network servers. The terminal 102 can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things device can be a smart speaker, a smart television, a smart air conditioner, a smart vehicle device, etc. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, etc. The server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

[0062] In one embodiment, as shown in Figure 2 , a media stream quality of service policy control method is provided. Taking the server 104 in Figure 1 as an example, the method includes the following steps:

[0063] Step S202, receiving a policy request of media stream quality of service sent by a gateway, the policy request including a policy identifier of quality of service determined by the gateway according to a media type contained in the media stream, the media type, and a media content parameter, the policy identifier corresponding to an initial policy scheme of media stream quality of service pre-set.

[0064] The media stream is a streaming manner, so that the streaming media is played on the network, which can include audio stream, video stream, touch stream, dynamic stream and other types. Different media streams require different transmission bandwidth, transmission delay, jitter rate, and different quality of service. The quality of service policy request can be formulated according to the type of media stream to improve the transmission quality.

[0065] Figure 3 For a schematic diagram of the media stream quality of service policy control method in one embodiment, it can include a media gateway, a dynamic policy engine, and a network perception engine. The application end or some intermediate processing node sends the media stream to the media gateway, which can confirm the media stream quality of service policy request according to the type of the media stream. The policy request can include the quality of service policy identifier, media type, and media content parameters. The policy identifier is determined based on the media stream, for example, the policy identifier is a multi-bit binary value, and the value of a certain bit is 1, which represents a specified media stream, such as 0001 for audio stream, 0011 for audio stream + video stream, and 0100 for touch stream. The media type can include audio stream, video stream, touch stream, dynamic stream, etc. The media content parameters can include the size and code rate of the media stream.

[0066] The media stream can have a pre-set initial media stream quality of service policy scheme, wherein one policy identifier can correspond to one initial policy scheme.

[0067] Step S204, generating a query request of a media processing node according to the policy request, and querying the resource state of the media processing node based on the query request.

[0068] The dynamic policy engine can generate a query request of a media processing node according to the policy request, which is used to query the resource state of the media processing node. When multiple media streams are transmitted at the same time, the quality of service of the media stream may be affected due to the occupation of the node, and the resource state of the media processing node needs to be queried. The resource state of the node can include node in use, node available, node occupation, node offline, etc. The dynamic policy engine supports distributed deployment, and can have multiple query interfaces with the network perception engine.

[0069] Step S206, obtaining the corresponding initial quality policy scheme based on the policy identifier, and updating the initial quality policy scheme according to the queried resource state of the media processing node, media type, and media content parameters to obtain an adjusted policy scheme.

[0070] The network perception engine can perform a refreshing operation on all nodes connected to the network perception engine after receiving the query request to obtain the latest resource state information of the nodes. The network perception engine can send the latest resource state information to the dynamic policy engine. The resource state information can include resource duty ratio, node address, etc. The resource duty ratio of a node can be queried through the node address. The target node is specified according to whether the node is busy.

[0071] According to the policy identifier in the policy request, an initial policy scheme of the media stream quality of service is obtained. The resource state, media type, and media content parameters of the queried media processing node are updated to the initial quality policy scheme, and an adjusted policy scheme is obtained.

[0072] In step S208, in response to the policy request, a policy identifier corresponding to the adjusted policy scheme is returned to the gateway to instruct the gateway to send the media stream to the target media processing node for processing according to the dynamically adjusted policy scheme.

[0073] The policy identifier corresponds to the policy scheme. The adjusted policy scheme includes a policy identifier, a node address, a quality of service parameter, etc. The policy identifier can be returned to the gateway. The gateway can obtain the latest node address according to the policy identifier and send the media stream to the target media processing node for processing.

[0074] In the above media stream quality of service policy control method, the policy identifier can be determined according to the media type of the media stream, and the resource state of the media processing node is queried. The policy scheme of the quality of service is dynamically adjusted according to the resource state of the media processing node. The media gateway can send the media stream to the target media processing node for processing according to the dynamically adjusted policy scheme. The node information is dynamically adjusted according to the node query, and the media stream quality of service policy control can be dynamically performed.

[0075] In some embodiments of the present disclosure, the adjusted policy scheme includes an address of a target media processing node processing the media stream corresponding to the policy request and a quality of service control parameter. The return of the adjusted policy scheme to the gateway to instruct the gateway to send the media stream to the target media processing node for processing according to the adjusted policy scheme includes:

[0076] According to the address of the target media processing node, the media stream is sent to the target media processing node for processing;

[0077] The policy identifier is sent to the target media processing node to instruct the target media processing node to call the quality of service control parameter in the adjusted policy scheme corresponding to the policy identifier to process the media stream.

[0078] The resource occupation ratio of the node can be queried by the media processing node address, the resource occupation ratio is compared with the quality of service control parameter, and the target media processing node is specified according to whether the node is busy. The target media processing node can be one or more. The adjusted strategy scheme can include the address of the target media processing node processing the media stream corresponding to the strategy request and the quality of service control parameter. The media stream can be sent to the target media processing node for processing. The target media processing node obtains the corresponding strategy scheme according to the policy identifier, and can call the quality of service control parameter in the adjusted strategy scheme corresponding to the policy identifier to process the media stream.

[0079] In some embodiments of the present disclosure, the resource state of the media processing node is queried based on the query request, including:

[0080] The resource state of the media processing node is refreshed, and the refreshed resource state of the media processing node is obtained.

[0081] After the network perception engine obtains the query request, the resource state of the media processing node can be refreshed, that is, the latest node resource state is obtained, and it is judged whether the node is idle or busy.

[0082] In some embodiments of the present disclosure, the policy identifier in the strategy request includes a policy identifier determined by the gateway based on the media type contained in the media stream and / or whether there is specified type of sensitive data in the media stream;

[0083] And when it is determined that the media stream contains a specified type of media type, and / or there is a specified type of sensitive data in the media stream, the received policy identifier is a specific policy identifier determined by the gateway.

[0084] The policy identifier can be identified by numbers, letters, symbols, etc. The policy identifier corresponds to the policy scheme. The policy identifier can be determined according to the media type contained in the media stream, and / or used to specify sensitive data. The media type can include video stream, audio stream, tactile stream, dynamic stream, etc. The sensitive data can include personal information, social attributes, etc. of the user, and also includes special face information, fingerprint information, etc. When the media stream contains a specified type of media type, and / or sensitive data, such policy identifier can be determined as a specific policy identifier.

[0085] In some embodiments of the present disclosure, Figure 4 The flowchart of the media stream quality of service policy control method in one embodiment is shown. Before generating the query request of the media processing node according to the strategy request, the method further includes:

[0086] Step 402, determining whether the policy identifier is a specific policy identifier of a pre-type;

[0087] If yes, a query request of the media processing node is generated according to the policy request.

[0088] Before the query request of the media processing node is generated, if it is judged that the policy identifier is a specific policy identifier of a specified type, special information can be processed, and then the query request of the media processing node is generated according to the policy request. For example, user privacy data is shielded, or face information and fingerprint information are encrypted.

[0089] In some embodiments of the present disclosure, the initial quality policy scheme is updated according to the resource state, the media type and the media content parameter of the media processing node to obtain an adjusted policy scheme, including:

[0090] The resource state, the media type and the media content parameter of the media processing node are compared with the content in the initial quality policy scheme;

[0091] According to the comparison result, the content in the initial quality policy scheme is adjusted and / or selected, and the adjustment and selection at least meet the service requirements of the media stream quality of service.

[0092] After the network-aware engine refreshes the node, the latest resource state of the media processing node can be obtained, the policy identifier can be obtained according to the type of the media stream, the policy identifier corresponds to the initial policy scheme, the initial policy scheme includes the original resource state, the media type and the media content parameter, and the latest information of the media processing node is compared to judge whether the parameters are adjusted and whether the node is replaced, according to the comparison result, the content in the initial quality policy scheme is adjusted and / or selected to meet the service requirements of the media stream quality of service.

[0093] In some embodiments of the present disclosure, before the initial quality policy scheme corresponding to the policy identifier is obtained, the method further includes:

[0094] If the initial quality scheme corresponding to the policy identifier is not obtained through the query, a new adjusted policy scheme is generated according to the resource state, the media type and the media content parameter of the media processing node, and the new adjusted policy scheme is associated with the policy identifier.

[0095] The initial quality scheme may be invalid or difficult to query due to poor network quality. If the initial quality scheme corresponding to the policy identifier is not obtained through the query, a new adjusted policy scheme can be generated according to the resource state, the media type and the media content parameter of the media processing node, and the policy identifier is selected to correspond to the policy scheme.

[0096] It should be understood that although each step in the flowchart involved in the above embodiments is shown in sequence according to the arrow, these steps are not necessarily executed in the order indicated by the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other orders. Moreover, as described above, at least part of the steps in the flowchart involved in the above embodiments can include multiple steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least part of other steps or steps or stages in other steps.
