Abstract
The invention concerns a method (300) and system (100) for interrupting a dispatch call. The method can be practiced in a dispatch communications system (100) having at least a first communications channel (162) for carrying voice traffic and a second communications channel (164) for carrying communications-enabling information. The method includes the steps of assigning (312) the first communications channel to at least a first caller (133) and a second caller (135) to permit the first and second callers to engage in a dispatch call and as the first caller has control over the first communications channel, transmitting (314) an interrupt message (505) over the second communications channel to inform the first caller of an interrupt status of the second caller. The transmitting step is performed without terminating the dispatch call.
