Abstract:
1. A method for registering a user equipment (UE) in an IP multimedia subsystem (IMS) the method comprising the steps of: A system comprising: a processor; a memory; a medium access engine, which is processed by the processor and the memory, operative to contend for access to a channel and to control transmission of data streams, the data streams belonging to a particular access class of a plurality of different access classes, the medium access engine operative to discriminate quality of service based on the different access classes; and a burst channel access engine, which is processed by the processor and the memory, operative to maintain a burst list having a transmission order of stations which is generated based on a received order of the transmitted data streams and to control transmission of the data streams based on the transmission order of the stations in the burst list, wherein the transmitted data streams are separated in transmission by a short interframe space (SIFS) interval, wherein the burst channel access engine at a station generates the burst list after the medium access engine at the station gains access to the channel for a data stream of a particular access class, and for each data stream belonging to the access class, the burst channel access engine monitors transmission of other stations to form a burst list of access stations with data streams belonging to the access class, and wherein when the burst channel access engine at the station monitors the data stream of the particular access class, other stations on the burst list with data streams for the access class subsequently transmit after an SIFS interval, without any channel contention from data streams of other access classes during transmission of data streams from the particular access class.
