    Abstract: Apparatus for testing one or more mobiles, each mobile being adapted to transmit and receive respective signals compatible with a cellular communications network. The apparatus includes station simulation circuitry which is adapted to simulate a plurality of base station controllers (BSCs) operative simultaneously in the cellular communications network. The apparat us also includes mobile interface circuitry which is coupled to transfer the respective signals between the station simulation circuitry and the one or more mobiles.

    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.

    Abstract: Testing apparatus, including a base station transceiver (BTS) simulator, which is adapted to simulate signals transmitted by a BTS and to process signals that are ordinarily received by the BTS. The apparatus also includes a channel simulation unit, which is adapted to provide a communication channel for the simulated signals and to communicate with a mobile cellular telephone, and a coupling connecting the BTS simulator and the channel simulation unit, enabling the BTS simulator and channel simulation unit to communicate digitally.
