1. A mobile repeater for relaying radio signals between mobile stations and one of at least a first and second base station of a cellular radio network, comprising:

  • a tunable downlink branch for receiving and demodulating data streams from base station radio signals, and for modulating, amplifying, and retransmitting said data streams as repeater radio signals in network standard format to the mobile stations;

    a tunable uplink branch for receiving and demodulating data streams from mobile station radio signals, and for modulating, amplifying and retransmitting said data streams as repeater radio signals in network standard format to the base station; and

    an intelligent control unit coupled to said downlink branch and said uplink branch for monitoring signaling traffic components of said data streams and for tuning said tunable downlink and uplink branches from frequency channels used for the first base station to frequency channels used for the second base station to support the handover of the relay connection from the first base station to the second base station.
