Data load redistribution within a relay enhanced telecommunication network
First Claim
1. A method for changing the data load distribution within a mobile wireless telecommunication network comprising a first base station, a second base station and a relay node being connected to the first base station and/or to the second base station, the method comprising:
- establishing for each of a plurality of user equipments a first indirect connection to the first base station via the relay node,establishing in a collective manner for each of the plurality of user equipments a second indirect connection to the second base station via the relay node,monitoring by the relay node of a plurality of base stations neighboring the relay node,determining a ranking of the monitored plurality of base stations, wherein the ranking is indicative of the suitability of each respective base station of the monitored plurality of base stations to act as the second base station,selecting a highest ranking base station of the monitored plurality of base stations as the second base station, andterminating in a collective manner for each of the plurality of user equipments the first indirect connection, wherein prior to terminating the first indirect connection, the relay node establishes a backhaul connection for data traffic to each of the first base station and the second base station.
