Abstract
A mobile communication device (214) in a communication system (200) initiates a call over the fixed equipment network of the communication system to another mobile communication device (216). If the two mobile communication devices are within sufficient proximity to each other, they may switch to a direct mode of communication. (318). The direct mode and network mode of communication are in different frequency bands using different air interface protocols.
