System and method for terminating a voice call in any burst within a multi-burst superframe

摘要

A system and method for effectively and reliably terminating a voice call in anyburst within a multi-burst superframe. A transmitting unit generates a terminationburst upon detecting a dekey event. The termination burst includes a data synchronizationpattern, a slot type field indicating an end of a call, and an information fieldsurrounding the data synchronization pattern and the slot type field. The informationfield is encoded from a predetermined voice encoder frame unique to the terminationburst. Once all buffered voice information is transmitted, the terminationburst is transmitted prior to the end of the multi-burst superframe. A base stationor other receiving unit monitors the incoming signal. Upon detecting the datasynchronization pattern, the receiving unit decodes the slot type field andthe information field. The receiving unit determines whether the decoded slottype field is indicative of the end of a call, and whether a specific portion ofthe decoded information field matches the predetermined voice encoder frame.If both are true, the receiving unit terminates the call.
