Abstract
An apparatus and a method are provided for multiplexing different sessions using the same authorized contexts for media. The method includes distinguishing different control plane sessions by a user equipment, and identifying media flows of a same application among the different control plane sessions by the user equipment by setting a service identifier. The method further includes sending the service identifier by the user equipment to a call state control function including a policy decision function, and authorizing quality of service for a user plane context by the policy decision function. Furthermore, the method includes enabling, by the policy decision function based on the service identifier, the different control plane sessions with media flows of the same application to share the same user plane context with the authorized quality of service to multiplex the different control plane sessions with media flows of the same application.
