Media Control at the Network Edge

Third party session control can be useful in many Internet of Things (IoT) use cases including monitoring and assistance of elderly and mission critical communications. Enhanced session control with media playing, collecting and recording interaction adds value and enables more information to be provided and gathered. The Multi-access Edge Computing (MEC), which brings the cloud computational and storage power at the network edge, can address many IoT use cases. The paper studies the capabilities of exposing media control to MEC applications. MEC Application Programming Interfaces that enable third party application to play media message, to collect and record media interactions within ongoing session, are presented. Media control data model is proposed. As a proof of the concept, state models supported by the network and MEC application are presented, formally described and verified.
