Claim:
A method of managing a unicast-based media session associated with a session identifier, said method comprising the steps of: a user terminal receiving channel identifiers of multiple available media channels; said user terminal generating a first Session Initiation Protocol (SIP) based channel request comprising a first channel identifier selected from said received channel identifiers and a port identifier of at least one media input port of said user terminal; said user terminal transmitting said SIP-based channel request to a network node for initiating delivery of media data of a first media channel to said at least one media input port; said user terminal transmitting a SIP-based termination message comprising said session identifier to said network node; said user terminal generating a second SIP-based channel request comprising a second channel identifier selected from said received channel identifiers and a port identifier of at least one media input port of said user terminal; and said user terminal transmitting said second SIP-based channel request to said network node for initiating delivery of media data of a second media channel to said at least one media input port, wherein said step of generating said second SIP-based channel request comprises said user terminal generating said second SIP-based channel request comprising said second channel identifier and a notification specifying that said at least one media input port identified in said first SIP-based channel request is to be re-used for said second media channel.
