    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: The present invention is a method and system for supporting a beamfonming antenna system in a mobile broadband communication network with an improved beam pattern, beam sweep pattern, pilot channel design with feedback and reporting rules, and control signaling design. Specifically, the improved beam pattern includes a method of supporting wireless communications in a wireless network forming at least two spatial beams within a cell segment where the at least two spatial beams are associated with different power levels, and separately, where at least two spatial beams can be moved across the cell segment according to a unique sweep pattern. The pilot channel design improves network bandwidth performance and improve user mobility tracking. Feedback and reporting rules can be established using a particular field designator, CQI, in the preferred embodiment.

    摘要: The present invention provides apparatus and methods for measuring multimedia demand and for maximizing broadcast channel utilization. A first, two way communications channel or channels, from a customer to a broadcaster are provided, as well as a second broadcast channel, which may be, in some embodiments, combined with the two way channel. A bid cycle is established for available programs, whereby one or more programs is listed as available on said two way channel, whereupon one or more customers may bid on those programs in order to view those programs. If the aggregated bids reached a threshold value, the broadcaster will then broadcast the program to the bidding customers, thus closing the bid cycle. If the threshold is not reached, the bid cycle is unsatisfied.
