Abstract: A method for providing a multicast and broadcast service (MBS) by transmitting a plurality of data frames in a wireless network. The method includes: generating a first MBS data information element (MBS-DATA-IE) in a first one of the data frames, the first MBS-DATA-IE including information relating to a logical channel of the MBS, and indicating a location of an MBS map (MBS-MAP) in a second one of the data frames; determining ones of the data frames between the first and second ones of the data frames in which to add a plurality of extra MBS-DATA-IEs; and generating the extra MBS-DATA-IEs, the extra MBS-DATA-IEs being generated in the determined ones of the data frames and including information relating to the logical channel.

Abstract: A system and method for reducing call establishment delay in wireless network is provided, in which a network node establishes a call to a wireless terminal controlled by an AP via a server. The wireless terminal notifies the server of its listen interval. In the power saving mode, the wireless terminal wakes up every listen interval and listen the beacon to check whether any buffered packet for it. When the wireless terminal learns from the beacon that there are packets waiting, it communicates with the access point to retrieve them. The server records a listen time at which the wireless terminal will wake up and listen to the AP based on the listen interval. When a network node calls the wireless terminal, the server buffers the request for a time interval based on the listen time, and then sends the request to the wireless terminal.

Abstract: Architecture for filing variable-bit-rate (VBR) video data on zoned disks based on the character of the VBR data and the character of the zoned disk. A "constant read-time" approach is disclosed to determine the filing layout of data. In this invention, the distribution of the data is determined by the sequence of retrieving the data. A multistage graph is used to describe the structure of the filing architecture of this invention. The invention also provides a segmentation algorithm to reduce time and space complexities in the processing of VBR data.
