ABSTRACT:
Communication networks and methods are disclosed for negotiating control over a PTT call between an OMA PoC network and a P25 network. If an OMA PoC PTT server receives a request for the PTT call from a calling party, then the PTT server transmits a call initiation message for the PTT call to the P25 network offering control over the PTT call to a PTT server in the P25 network. The P25 PTT server processes the call initiation message to identify the offer for control, assumes control over the PTT call, and determines whether the calling or called party has the floor for initial transmission for the PTT call. The P25 PTT server then transmits a response message to the OMA PoC PTT server indicating which one of the calling or called party has the floor. The party granted the floor may then initiate voice communications for the PTT call.
