Abstract

A method of determining whether to communicate or handover between trunked mode and direct mode in a communications system having a first mobile station and a second mobile station communicating via a base station using a first frequency on an uplink communication and a second frequency on a downlink communication. The method includes receiving a transmitted signal from the first mobile station on the first frequency at the second mobile station and at the base station, receiving the transmitted signal from the base station on the second frequency at the second mobile station, and determining whether to communicate in direct mode based on the received signals.
