Communication terminal, system and a method for establishing a communication link

摘要

A terminal such as mobile station (101) includes an RF transceiver (203) for communication by an RF link with another terminal (105) and an infrared transmitter (214) operable to send an infrared signal to the other terminal (105) to establish an initial communication link with the other terminal. Also described is a method of establishing a wireless communication link between a first terminal (101) and a second terminal (105) including sending an infra-red signal from the first terminal to the second terminal to request the second terminal to indicate its identity, sending a signal in response from the second terminal to the first terminal indicating the requested identity and using the requested identity received from the second terminal by the first terminal to establish an RF link with the second terminal. Also described is a system of terminals which can operate to form a communication link by the method.
