Abstract
A method and apparatus of linking communication systems of different types. Call requests are directed from a sourcing communication unit in a first communication system (101) to a gateway (114), which translates identity and call type information from the first system to at least one other system (113). Next, the gateway requests radio frequency (RF) resources from each system to support the call. After sufficient RF resources have been received, and prior to the sourcing communication unit starting a call, the gateway (114) issues call start information to each of the communication systems (101, 113). Then, the gateway (114) is operable to receive and translate a message payload from the sourcing communication unit and distribute the translated message payload to communication units in the at least one other system.
