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.

Claims

1. 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.

2. Method according to claim 1, wherein the step of transmitting data includes the step of transmitting a synchronizing signal in each package.

3. Method according to claim 1, wherein the step of applying includes dividing each frame into time slices of equal length.

4. Method according to claim 1, wherein the step of transmitting data includes the step of transmitting a synchronizing signal in each package, wherein said synchronizing signal includes data distinguishing said information packages from said control packages.
