  • Patent number: 8185144
    Abstract: In a method for managing a target system from a Push-to-Talk station, a Gateway receives a request to manage the target system from the Push-to-Talk station. The request includes an identifier for the Push-to-Talk station and an identifier for the target system. A push-to-talk call session is established between the Push-to-Talk station and the Gateway. A second communication session is established between the target system and the Gateway using an appropriate protocol supported by the target system. The Gateway Transformer translates messages from the Push-to-Talk station into formats and protocols registered for use with the Push-to-Talk station for controlling and querying the target system.
