A communication system () includes a first communication unit () capable of communicating over a full-duplex persistent-connection link provided by a full-duplex network () and a second communication unit () capable of communicating over a half-duplex dispatch link provided by a dispatch RF system (). The system () also includes a dispatch gateway (). The dispatch gateway () receives signals from a first communication unit () over a full-duplex persistent link through a full-duplex network () and provides communication between the first communication unit and a single dispatch communication unit () or a group of dispatch communication units () over a half-duplex communication link through a dispatch RF system (). The gateway operates in a manner so as to permit communication between full-duplex terminals () and half-duplex terminals ().

Method and apparatus for interactive communication between half-duplex and full-duplex systems

A method in a wireless communication device including requesting contextual information from a source outside the wireless communication device, the contextual information requested by a context aware application on the wireless communications device, and providing alternate contextual information to the context aware application with a contextual information discriminator of the wireless communications device when contextual information from the source from which contextual information is requested is not available.
