Patent ID: 6965768

Claim:
A method for allocating a channel requested for a telecommunication link via a telecommunication network between a caller and a called party, the method comprising the steps of: selecting at least one physical channel having a different wanted-to-unwanted signal ratio when a data channel is requested than when a voice channel is requested such that at least one physical channel having a better wanted-to-unwanted signal ratio is preferentially selected when a data channel is requested than when a voice channel is requested, wherein the better wanted-to-unwanted signal ratio of a data channel compared with a voice channel is achieved by allocating, in a mobile radio cell, at least one physical channel in each case to a data channel a disturbance of which by physical channels of at least one of identical and adjacent frequencies in adjacent radio cells is less than in the case of other physical channels; and allocating the selected physical channel for an air interface in a mobile radio network.
