Abstract
In one embodiment, a method and apparatus of multiplexing and demultiplexing radio channels includes receiving data through at least one multicast media channel available for use in an Internet Protocol Interoperability and Communications System (IPICS) comprising multiple communication endpoints linkable to a Land Mobile Radio (LMR) in the IPICS; channel mapping the at least one multicast media channel to multiple media channels of the LMR; receiving an audio signal through the at least one multicast media channel; controlling access to the LMR by applying communication access control policies based on the received data upon reception of the audio signal; and operatively linking the LMR to a specified endpoint through the at least one multicast media channel based on the communication access control policies.
