Abstract: A method and system for performing multicast broadcast handover in a wireless data network are disclosed. Each cell broadcasts administrative announcements over a logical channel to mobile terminals. The announcements indicate which multicast broadcasts are available in specified cells, as well as connection information for each cell. The mobile terminals may tune to a multicast broadcast as defined by the administrative announcements. While tuned to the multicast, the mobile terminal continues to receive administrative announcements. As the broadcast fades out or is otherwise interrupted, the mobile terminal can retune to the same multicast broadcast in another cell, based on the cell connection information included in the previously received administrative announcements.

Abstract: The invention relates to signalling in broadcast and multicast environments. For a service in the broadcast is defined an indicator, which is formulated into a unique indicator. The indicator is mapped into one time-slot in a signalling channel. A notification relating to the service is transmitted during the said time-slot. The notification is used for enabling the receiver for receiving said service, wherein the receiver may be turned off at other times.

Abstract: An apparatus, system method, and computer program product that combine the attributes of ALC and NORM for communicating data between devices on a network. A sending device uses multiple data rates on different channels to reliably send data packets and receivers use NACKs to request retransmission of missing or mangled data from the sending device or other receiving devices on the network. The sending device using an active ALC mechanism and the receiving devices use NACK and transmitting mechanisms for transmitting acknowledgements or data from the device. The sending and receiving devices can be located in the same or in different networks for communicating data packets during a data transmission session.
