A method for establishing a communication link between a telecommunications network and a mobile station via a local station connected to said telecommunications network and a short range radio channel between said local station and said mobile station comprises a step in which at least one property of said radio channel is negotiated between said local station and said mobile station, a step in which said mobile station enters a power saving mode, a step in which said mobile station enters an active mode, and a step in which said local station links said mobile station to said telecommunications network via said radio channel using said at least one negotiated property. A local station and a mobile station have corresponding features. The invention is especially adapted for portable telephone and data transmission devices.
