Abstract:
1. A method for interrupting a communication unit transmitting a call in a communication system, the method comprising: assigning the call to a communication channel; receiving the call from the communication unit on an inbound link of the communication channel; determining whether the communication unit should be interrupted; sending an interrupt grant to a base site upon determining that the communication unit should be interrupted; generating, at the base site, an interrupt message upon receiving the interrupt grant; and broadcasting the interrupt message to the communication unit; wherein broadcasting the interrupt message includes broadcasting the interrupt message on an outbound link of the communication channel; wherein the inbound link is comprised of a first time division multiple access (TDMA) time slot and the outbound link is comprised of a second TDMA time slot; wherein the second TDMA time slot is comprised of a plurality of TDMA bursts, and wherein broadcasting the interrupt message includes broadcasting at least a portion of the interrupt message within an embedded signaling information field of one or more of the plurality of TDMA bursts.
