Abstract

A method for providing switching of a media session transmitted from a content server to a user equipment from a multicast to a unicast bearer. A preparation trigger recognised by the user equipment triggers a preparation phase wherein an application server prepares for an upcoming 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.
