Abstract
A method of managing a unicast-based media session is disclosed. A user terminal having access to channel identifiers of media channels available at a media server compiles a SIP-based channel request comprising a channel identifier of one of the available media channels and a port identifier of at least one media input port of the terminal. This message is sent to a network node for initiating delivery of media data of selected media channel to the announced media input port. The SIP-based data signaling also allows switching between unicast-based media channels and switching between unicast-bast and multicast/broadcast-based media channels during the ongoing media session.
