Patent ID: 7092736

Claim:
A radio communication system, comprising: a base station to transmit first signals for first communication connections, the first signals being transmitted via an air interface using a first carrier frequency, and to transmit second signals for second communication connections, the second signals being transmitted via the air interface using a second carrier frequency; a first radio network controller to communicate the first communication connections with the base station; and a second radio network controller to communicate the second communication connections with the base station; the base station comprising: a common high-frequency component which processes signals of the first communication connections and signals of the second communication connections; a first communication port and a second communication port, the first communication port being connected to the first radio network controller and the second communication port being connected to the second radio network controller, wherein in the base station, the first communication connections are communicated via the first communication port and the second communication connections are communicated via the second communication port, and the base station assigns the first and second communication connections respectively to the first and second communication ports on the basis of connection identifiers provided in data of the first and second communications connections.
