Abstract: A transcoder architecture and method for transcoding in land mobile radio (LMR) systems are provided. The LMR system (20) includes a first communication site configured to communicate using a first LMR communication protocol and a second communication site configured to communicate using a second LMR communication protocol. The LMR system further includes a transcoder (28) configured to receive LMR content from the first communication site communicated using the first LMR communication protocol and digitally convert the LMR content to the second LMR communication protocol to be communicated to the second communication site.

Abstract: A system and method for heartbeat signal generation are provided. The method (30) includes determining (38) a communication condition and generating (42) heartbeat signals based on the determined communication condition. The system (20) includes a plurality of communication cells (26) and at least one communication device (28) configured to generate heartbeat signals. A rate of generating the heartbeat signals is based on one of (i) a service priority or user group and (ii) communication requirements for a network type for each of the plurality of communication cells.

Abstract: A system and method for managing communication in a cellular communication system are provided. The method (30) includes measuring (32) communication conditions within at least one communication cell of the communication system and estimating (34) congestion within the at least one communication cell of the communication system based on the measured communication conditions. The method further includes adjusting (40, 42) communication links within the at least one communication cell based on the estimated congestion.
