Method and apparatus for providing quality of service for web-based real-time communication

A network device for web-based real-time communication, the network device comprising:

• a network interface;
• and
• a processor that controls the network interface to:
• establish a websocket connection with a user equipment (UE) for web traffic of a web-based real-time communication service,
• receive, from the UE, a bearer setup request message requesting establishment of a signaling bearer for signaling messages of the web-based real-time communication service, before transmitting the signaling messages related to the web-based real-time communication service,
• obtain information on a policy and charging control (PCC) rule to be applied for the signaling messages of the web-based real-time communication service on the bearer, the PCC rule including service data filter information and quality of service (QoS) parameters with a higher priority than the web traffic of the web-based real-time communication service,
• establish the signaling bearer with the UE based on the PCC rule, and
• communicate the signaling messages for the web-based real-time communication service with the UE through the websocket connection and the signaling bearer, according to the service data filter information and the QoS parameters included in the PCC rule,
• wherein the web traffic of the web-based real-time communication service and the signaling messages of the web-based real-time communication service are transmitted via the websocket connection and the signaling bearer, respectively, and
• wherein the UE waits until the signaling bearer is established before transmitting the signaling messages related to the web-based real-time communication service.
