1. A method comprising:
- receiving a request to initiate a call being one of a data-only call and a voice-only call;
selecting one of a plurality of pre-defined call profiles responsive to the request to initiate the call, each call profile being associated with a respective handle, each call profile defines one or more parameters, including one or more of data rate in a channel, data rate adaptation, full/half duplex, and speech codec type, for communication between a mobile station and a mobile switching center;
establishing a wireless communications link with an opposing party; and
,transmitting a call setup request containing said associated handle to said opposing party.
