Abstract:
1. A method for communicating land mobile radio (LMR) content, comprising: selecting, with an LMR unit, a preferred network from among a plurality of networks to be used for communicating LMR content, said plurality of networks including an LMR network and a cellular data network; selectively providing an LMR protocol header to the LMR content and using an LMR transmitter to communicate said LMR content to said LMR network if said LMR content is to be communicated using the LMR network; selectively IP encapsulating said LMR content at said LMR unit using a packet switch protocol header, and using a cellular radio modem to communicate the encapsulated LMR content to a cellular data network if said LMR content is to be communicated using the cellular data network; receiving said IP encapsulated LMR content at said cellular data network; decapsulating said LMR content in said cellular data network, by removing the packet switch protocol header; processing said LMR content in at least one processor in said cellular data network to selectively determine at least one action which is to be performed, wherein said at least one action includes determining if said LMR content is to be routed to said LMR network or said cellular data network; reencapsulating said LMR content for transmission within one of the LMR network and the cellular data network; and selectively routing said LMR content to a destination within one of said LMR network or said cellular data network based on said processing step.
