Abstract
A communication system () provides for improved dispatch communications, by providing a method for monitoring the signal quality at each of the Mobile Stations (MS) involved in a dispatch call. Once engaged in the dispatch call, the MSs () monitor the signal quality of their ACCH channel () and send a message back to the system () if their signal quality falls below a predetermined threshold. If the signal quality of any dispatch call participant falls below the given threshold (), the system alerts all the dispatch call participants () thereby avoiding any loss of communications, and tears down the previously set up dispatch call. If the signal quality becomes acceptable again () for those MS who had previously experienced poor signal quality, they send a message to the system, which automatically sets up a new dispatch call and alerts all the dispatch participants that the dispatch channel can be used again ().
