SYSTEM AND METHOD FOR ENHANCING INTEROPERABILITY BETWEEN MOBILE COMMUNICATION SYSTEM COMPONENTS USING DIFFERENT AUDIO ENCODING FORMATS

摘要

A system and method for improving the interoperability of communication system components using multiple audio encoding formats within a single talkgroup is provided. The system includes at least two base site repeaters, each of which may be configured to receive and process voice calls from communication units using different audio encoding formats. The system also includes a transcoder provided at either the base sites or as a separate infrastructure server. When a voice call is transmitted to a first repeater using a first audio encoding format, the audio signal is transcoded by the transcoder and provided to a second repeater using a second audio encoding format. The second repeater then broadcasts the voice call to any communication unit within range using the second audio encoding format
