Abstract
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 Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
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.
Claim 2
Dependent Claim
141 words
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.
Claim 3
Dependent Claim
22 words
Method according to claim 1, wherein the step of transmitting data includes the step of transmitting a synchronizing signal in each package.
Claim 4
Dependent Claim
20 words
Method according to claim 1, wherein the step of applying includes dividing each frame into time slices of equal length.
Claim 5
Dependent Claim
36 words
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.
