1. A method for communicating land mobile radio (LMR) content, the method comprising:
- assigning a different traffic multicast Internet Protocol (IP) address to each of a plurality of groups of LMR users;
encapsulating the LMR content within IP packets; and
transmitting the IP packets to one of the plurality of groups of LMR users using at least one of the assigned traffic multicast IP addresses.

Abstract
A method for radio frequency multicasting and a multicast site architecture are provided. The method includes assigning a different traffic multicast Internet Protocol (IP) address to each of a plurality of groups of LMR users and encapsulating the LMR content within IP packets. The method further includes transmitting the IP packets to one of the plurality of groups of LMR users using at least one of the assigned traffic multicast IP addresses.

15. A method for providing land mobile radio (LMR) radio frequency (RF) communication, the method comprising:
-
defining a control plane using at least one control multicast Internet Protocol (IP) address, the control plane communicating call control and signaling information to a plurality of LMR units; and defining a traffic plane using at least one traffic multicast IP address, the traffic plane communicating encapsulated LMR content to at least one of the plurality of LMR units associated with a group of LMR users. - View Dependent Claims (16, 17, 18)

19. A multicast site architecture for communicating land mobile radio (LMR) content, the multicast site architecture comprising:
-
a plurality of communication sites; and an LMR over Internet Protocol (IP) interface associated with at least one of the plurality of communication sites, the LMR over IP interface configured to transmit call control and signaling information to a plurality of LMR units using at least one control multicast IP address and to assign at least one traffic multicast IP address to communicate LMR content between a group of LMR users. - View Dependent Claims (20)
