Method and apparatus for quality of service assurance for WebRTC sessions in 5G networks

An apparatus comprising:

• a communication interface;
• and
• a processor operably coupled to the communication interface, the processor configured to:
• receive an expected service level agreement (SLA) for a media service from a service provider, wherein the media service includes a plurality of media flows;
• provision a network slice that includes media functions based on the expected SLA;
• configure the media functions in the network slice with flow prioritization information for each media flow among the plurality of media flows;
• determine performance of each of the media flows;
• perform adjustment of service parameters based on the determination that the performance of one or more of the media flows is below the expected SLA;
• configure network segments in the network slice with different parameters based on a priority level for each network segment;
• transfer the media flows through the network segments based on priority levels for the media flows;
• and
• set a delay configuration for each of the network segments to set the priority level for each network segment.
