发明名称 Broadcast hand-over in a wireless network
摘要 A system and method are disclosed for providing multicast channel handover in a mobile device within a mobile network. First and second transmitters within first and second cells broadcast datagrams associated with a logical identifier according to link-level access parameters common to the first and second transmitters. A mobile device receives the broadcast datagrams for the logical identifier from the first transmitter by configuring the common link-level access parameters. As part of handover from the first cell to the second cell, the mobile device continues receiving the broadcast datagrams from the second transmitter by maintaining the common link-level access parameters. In one embodiment, the datagrams are IP datagrams transmitted in an MPEG2 transport stream. The link-level access parameters may include time slice parameters associated with burst transmissions from the first and second transmitters according to an embodiment of the invention.
