A METHOD AND EQUIPMENT FOR PROVIDING UNICAST PREPARATION FOR IPTV

摘要

A method for providing switching of a media session transmitted from server to a user equipment from a multicast to a cast bearer. A preparation trigger recognised by the user equipment triggers a preparation phase where in an application server prepares for an up-coming switch by re-configuring the media session and by providing the re-configuration data to the user equipment. Subsequent to the preparation phase, a second trigger triggers a release phase, wherein the multicast bearer is released, and the media session is resumed by the unicast bearer.
