Abstract  Abstract

There is provided a method of a first mobile communication device for supporting a combinational circuit switched and packet switched session with other communication devices. During a combination session (100) between first and second mobile communication devices (110, 120), the first mobile communication device may forward or duplicate data to a third mobile communication device (210) without intervention from a remote server. There is also provided a method for supporting supplementary services in a combinational circuit switched and packet switched session between three or more mobile communication devices (110, 120, 210). Data is communicated between first and second mobile communication devices (110, 120) via a packet switched data session (140) while maintaining a circuit switched call session (130) between the first and second mobile communication devices. A multi-party conference call which includes the first and second mobile communication devices (110, 120) and one or more other mobile communication devices (210) is then established via the circuit switched call session (130, 220) while maintaining the packet switched data session (140) between the first and second mobile communication devices (110, 120).
