1. A method for communicating land mobile radio (LMR) content, said method comprising:
- selectively determining, at an LMR radio unit, whether said LMR content will be wirelessly communicated from said LMR radio unit using a cellular data network having a cellular airlink protocol or an LMR network having an LMR airlink protocol;
if the LMR content is to be wirelessly communicated using the cellular data network thenforming, by a cellular data network communication module of said LMR radio unit, first encapsulated LMR content by encapsulating the LMR content using a first packet switching protocol header, andcommunicating said first encapsulated LMR content from said cellular data network communication module of the LMR radio unit to an LMR base station at least partially using a cellular data network employing said cellular airlink protocol; and
if the LMR content is to be wirelessly communicated using the LMR network thencommunicating said LMR content from an LMR communication module of said LMR radio unit to said LMR network using said LMR airlink protocol,receiving said LMR content at said LMR base station, andencapsulating said LMR content at said LMR base station using a second packet switching protocol header so as to form second encapsulated LMR content;
wherein said LMR content is generated by a common LMR application module comprising said LMR communication module of said LMR radio unit and said cellular data network communication module of said LMR radio unit.

Abstract
A system and method for providing land mobile radio (LMR) content using a cellular data network is provided. The method includes communicating the LMR content via at least one of an LMR network and a cellular data network. The method further includes encapsulating the LMR content using a packet switching protocol when communicating the LMR content via the cellular data network.

11. A system for communicating land mobile radio (LMR) content, said system comprising:
-
an LMR radio unit comprising at least one computer processor and performing the following operations; selectively determining whether said LMR content will be wirelessly communicated from the LMR radio unit using a cellular data network having a cellular airlink protocol or an LMR network having an LMR airlink protocol; if the LMR content is to be wirelessly communicated using the cellular data network, then forming, by a cellular data network communication module of said LMR radio unit, first encapsulated LMR content by encapsulating the LMR content using a first packet switching protocol header, and communicating said first encapsulated LMR content from said cellular data network communication module to an LMR base station at least partially using a cellular data network employing said cellular airlink protocol; and if the LMR content is to be wirelessly communicated using the LMR network then communicating said LMR content from an LMR communication module of said LMR radio unit to said LMR network with an LMR transmitter using said LMR airlink protocol; and at least one LMR base station receiving said LMR content, and then encapsulating said LMR content which has been received using a second packet switching protocol header so as to form second encapsulated LMR content; wherein said LMR content is generated by a common LMR application module comprising said LMR communication module of said LMR radio unit and said cellular data network communication module of said LMR radio unit. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
