Telecommunication network with improved access protocol

摘要

A telecommunication network including a plurality of secondary stations and a primary station wherein the secondary stations a least partially share a common transmission channel to the primary station, thus obtaining high data transmission efficiency under high load conditions. To prevent interference, an access protocol is employed according to which all secondary stations which have data to transmit send transmission request signals to the primary station. The primary station then transmits to those secondary stations an allocation signal assigning respective time slots to them. The secondary stations then transmit in their assigned time slots. Directly upon completion of transmission in its assigned time slot a secondary station transmits a further transmission request signal to the primary station it such secondary station still has further data to transmit.
