摘要： It provides a method for multicast group management. The apparatus determines a request for joining a multicast service derived during establishment of a connection for carrying multicast service between a first device and a second device, and it sends a message indicative of joining said multicast service based on the request for joining if the multicast service is not available in said network device. As a consequence, it reduces the messages exchanged in unreliable wireless connection so as to reduce the probability of service interruption.

摘要： A method for reporting state information is provided. The receiver device receives a service, which is encoded in at least two layers over a communication channel, through a subset of said at least two layers; it measures a channel quality parameter; and in response to the channel quality parameter reaching a predetermined threshold value, it receives the service through a modified subset of the at least two layers as a function of the measured channel quality parameter and transmitting state information of the receiver device. Thus, the signal overhead is reduced.

摘要： A method of a mobile station receiving data packets from a serving base station via a multicast or broadcast connection in a wireless network is provided for performing a handover from the serving base station to a target base station. The method comprises, at the level of the mobile station, the steps of: upon the detection of the quantity of buffered data packets in the mobile station being lower than a first threshold value, establishing a unicast connection with the serving base station to receive data packets from the serving base station; and upon detection of the level of buffered data packets reaching the predetermined threshold level, performing a handover from the serving base station to the target base station. According to the invention, a seamless handover of a mobile station in a wireless network providing Multicast and Broadcast Service (MBS service) can be achieved to prevent the MBS service interruption during the handover.
