Transfer of data packets in a wireless telecommunications system

摘要

A wireless telecommunications system is provided for connecting to a data link and for routing data packets between the data link and a subscriber terminal. The wireless telecommunications system provides a group of communication channels arranged to utilise a radio resource. The group is shared by a plurality of subscriber terminals. A subscriber controller within the subscriber terminal is arranged, when a data packet is to be transmitted to the data link, to acquire a communication channel from the group to enable that data packet to be transmitted. A resource monitor is then used to receive information concerning traffic loading, and to apply predetermined criteria to determine how long the communication channel may be acquired for by the subscriber terminal before causing the subscriber controller to release the communication channel.
