1. A method for operating a radio telecommunications system comprising a mobile station and two or more cell site units each capable of communicating by radio with the mobile station on at least two communication channels having different frequencies;
- wherein the mobile station is in traffic communication on a traffic communication channel with at least two of the cell site units;
the method comprising;
the mobile station receiving signals for each of said two or more cell site units on each of the at least two communication channels;
the mobile station determining an estimate of the level of interference with signals on each of the at least two communication channels for each of said two or more cell site units;
the mobile station communicating to a handover controller the estimate of the level of interference with signals with each of the at least two communication channels for each of said two or more cell site units; and
the handover controller determining to which of the cell site units to hand over traffic communication of the mobile station on the basis of at least the estimates of the level of interference with signals on each of the at least two communication channels for each of the two or more cell site units.

10. A mobile station for operation in a telecommunications system comprising at least two cell site units, wherein the mobile station is in traffic communication on a traffic communication channel with at least two of the cell site units, each cell site unit being capable of communicating by radio with the mobile station on at least two communication channels having different frequencies;
- the mobile station comprising;
a receiver capable of receiving signals from a cell site unit on a communication channel; an interference estimation unit for estimating the level of interference on a communication channel on which the receiver receives signals; a channel analysis unit coupled to the receiver and the interference estimation unit for causing the receiver to receive signals from each of the cell site units on each of the respective communication channels in turn and receiving from the interference estimation unit an estimate of the level of interference on each of the at least two channels; and a transmitter coupled to the channel analysis unit for transmitting to the mobile station communicating to a handover controller the estimate of the level of interference with signals with each of the at least two communication channels for each of the at least two cell site units; wherein the mobile device is arranged to perform a handover in dependence on the handover controller determining to which of the cell site units to hand over traffic communication of the mobile station on the basis of at least the estimates of the level of interference with signals on each of the at least two communication channels for each of the at least two cell site units. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method for operating a radio telecommunication system comprising a mobile station and two or more cell site units, wherein the mobile station is in traffic communication on a traffic communication channel with at least two of the cell site units, each cell site unit being capable of communicating by radio with the mobile station on at least two communication channels having different frequencies;
- the method comprising;
the mobile station storing an indication of the timing difference between signals on the communication channels; the mobile station receiving signals on one of the communication channels; and the mobile station interrupting said receiving in order to receive signals on another of the communication channels at a time dependent on the stored indication; the mobile station determining an estimate of the level of interference with signals received on each of the communication channels for each of the two or more cell site units; the mobile station communicating to a handover controller the estimate of the level of interference with signals with each of the communication channels for each of the two or more cell site units; and the handover controller determining to which of the cell site units to hand over traffic communication of the mobile station on the basis of at least the estimates of the level of interference with signals on each of the communication channels for each of the two or more cell site units.
