HANDOFF IN A HYBRID COMMUNICATION NETWORK

Abstract A method of effecting handoff of a mobile station from a first base station in a first cellular communications system (46) controlled by a first mobile switching control station to a second base station in a second, different cellular system (48) controlled by a second mobile switching control station is described. The method comprises measuring at the mobile station a parameter of a signal transmitted by said first base station and a parameter of a signal transmitted by said second base station. When the parameters reach a predetermined condition, a signal quality message is communicated from the mobile station via the first base station to said first mobile switching control station, which responds by generating information for a channel request message for the second mobile switching control station and transmitting the same to the mobile station.
