A method, system and memory are provided for enabling interoperability. A
communication session between different communication systems, such as
radio systems, operating using different protocols is initiated by
receiving a scenario identifier from one of the user devices. An
interoperability server receives the scenario identifier and accesses
interoperability data to obtain the connection information corresponding
the scenario matching the scenario identifier. The data includes
scenarios for communication sessions and the connections required for
each scenario. Once the interoperability server obtains the connection
information, the communication session is initiated.
