<p>According to an exemplary embodiment an architecture for a new integrated TDMA system capable of carrying circuit data (e.g., voice, video, ISDN), packet data (e.g., X.25, Frame Relay, Internet, LAN), and ATM cells is disclosed. The architecture may be used for satellite and wireless TDMA networks, for example. For this transmission formats for bursts (101), channels (130, 140), TDMA frames (10) are defined and an adaptation layer for the three traffic types is described. In addition, the network has to carry its own management traffic and provide timing and control information to all terminals. For this the invention defines special bursts and along with their associated properties and formats. Each burst contains a data section which is divided into a number of channels. Each of the channels is adapted to carry protocol data units (141, 142, 143) which enable the system to efficiently allocate data according to its individual format or protocol thereby enabling maximum use of available bandwidth under prevailing communication conditions.</p> |
