Method for transferring data packets
First Claim
1. A method for transferring data packets in a network of user stations, the data packets being transferred over a set of channels with a frequency-hopping method and the channels being in this context selected for data transfer in accordance with a frequency-hopping pattern in temporally successive time slots, and there being assigned to a user station time slots in which it is authorized to transmit as needed, wherein in a first frequency-hopping pattern, data packets are transferred as needed, and in at least one second frequency-hopping pattern orthogonal to the first frequency-hopping pattern, data packets are transferred in a redefinable time grid, synchronously in the network, and wherein each user station has a transmission/reception section that is set alternatively on a channel from the first or the second frequency-hopping pattern.

Abstract
A method for transferring data packets in a network of user stations is described, the data packets being transferred over a set of channels with the frequency-hopping method and the channels being in this context selected for data transfer in accordance with a frequency-hopping pattern in temporally successive time slots. Time slots in which a user station is authorized to transmit are assigned to it as needed.

- 12. A central station for a network of user stations which transfers data packets, such that the data packets are transferred over a set of channels with a frequency hopping method and the channels are in that context selected for data transfer in accordance with a frequency-hopping pattern in temporal succession, the central station having a first transmission/reception section which processes a first frequency-hopping pattern in order to transfer data packets in load-dependent fashion to/from the user stations and a second transmission/reception section that processes, approximately simultaneously, a second frequency-hopping pattern, orthogonal to the first frequency-hopping pattern, in order to transfer data packets in a predefinable time grid.
- 14. A user station for a network of such user stations which transfers data packets, such that the data packets are transferred over a set of channels with a frequency-hopping method and the channels are in that context selected for data transfer in accordance with a frequency-hopping pattern in temporal succession, such that the user station is equipped to store a first frequency-hopping pattern and process it as specified by a central station, wherein the user station is equipped to store two frequency-hopping patterns and call them up selectively in order to transfer a data packet, data packets being transferred in load-dependent fashion in the first frequency-hopping pattern and data packets being transferred in a predefinable time grid in the second frequency-hopping pattern orthogonal to the first.
