Abstract

A system and method for connecting two or more peripheral stations to a central station over a common service resource. Each station is connected to one or more switching units; the common service resource is adaptively shared as a function of traffic going to and from the switching units. In one embodiment, capacity in the common service resource is divided into a series of frames, each frame having a set number of time slices, with information form one or more of the switching units being transferred within a time slice. In one such embodiment, time slices which will not be used during a particular frame due to the lack of or repetitive nature of information from a particular switching unit can be used to transfer information from a different switching unit.

Claims4

Dependent claims

Method in a radio communications system for transferring digital signals consisting of segments of user data between a transmitting station and a receiving station through a radio channel, including the steps of:

analyzing consecutive segments of said data with respect to content and amount of data that is to be transferred;
adaptively assigning channel capacity based on said analyzing;
applying said signals to a time frame structure, each frame having a predetermined number of time slices;
transmitting data included in said time slices as packages through said radio channel;
transmitting control data from said transmitting station to said receiving station, said control data being provided in control packages in time slices of said time frame structure;
and
assigning dynamically and selectively to said signals time slices in said frame structure, said slices of user data signals being transmitted as information packages.
