摘要： A mobile telephony network comprises base stations operating according to a predetermined standard. A transfer node allows the transfer of data from a first base station to a second base station in the mobile telephone network. Data is sent from the first base station to a data receiver of the data transfer node via a first wireless communications channel complying with the said standard. The received data is transferred via an interface within the transfer node to a data sender of the data transfer node. The data sender sends the transferred data to the second base station via a second wireless communications channel complying with the said standard. The interface within the transfer node does not comply with the operating standard because it transfers data only within the node. Data may be sent from the second base station to the first base station via the node in similar manner. Preferably, the receiver appears to the first base station to be a relay and the sender appears to the second base station to be a user terminal.
