Push-to-talk/cellular networking system
First Claim
1. An arrangement for providing inter-operability by a mobile device and a family radio service (FRS) radio comprising:
- a mobile network for coupling the mobile device for communication; and
a FRS gateway coupled to the FRS radio and to the mobile network, the FRS gateway for converting analog signals from the FRS radio and digital signals from the mobile device.

Abstract
A mobile device (80) is coupled to a dispatch server (50) via a mobile network (60, 70) and an internet protocol network (40). The mobile device triggers a push-to-talk request which is processed by the dispatch server. The dispatch server then transmits this push-to-talk request to a family radio service (FRS) gateway (30). FRS gateway (30) converts this digital request to an analog request and broadcasts the request via a base station 20 to a family service radio (10). The FRS radio can broadcast back to the FRS gateway, which will vocode the analog request, and transmit it back to the mobile device via the dispatch server. This invention allows mobile devices (cellular) equipped with PTT applications to network with FRS radios.

14. A method for networking a mobile device with a family radio service (FRS) radio comprising the steps of:
-
transmitting by the mobile device a session initiation protocol (SIP) invite message including at least a destination to a dispatch server;
sending by the dispatch server the SIP invite message to an FRS gateway associated with the destination; and
converting digital signals from the mobile device to analog signals for transmission to the FRS radio and for converting analog signals from the FRS radio to digital signals for transmission to the mobile device by the FRS gateway. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
