Abstract: A unique method for supervising a cellular telephone call between a base station and a radio telephone of a TDMA cellular communications system includes the steps of detecting the presence of the assigned time slot (306); detecting the presence of the assigned DVCC when the assigned time slot is detected (308); incrementing a bad slot counter (316) if the assigned time slot is not detected or if the assigned DVCC is not detected; and terminating the communication (322) if the bad slot counter reaches a predetermined maximum value. A good slot counter is incremented (310) when the assigned DVCC is detected in a burst. The good slot counter is reset (318) if the assigned DVCC is not detected in the next burst, and both counters are reset (314) if the assigned DVCC is detected in consecutive bursts.

Abstract: A unique method for supervising a cellular telephone call between a base station and a radio telephone of a TDMA cellular communications system includes the steps of determining (304) that the assigned time slot is expected to be received within a predetermined amount of time; detecting the presence of the assigned time slot (306) within the predetermined amount of time; detecting the presence of the assigned DVCC when the assigned time slot is detected (308); incrementing a bad slot counter (316) [if] responsive to the assigned time slot is not detected within the predetermined amount of time or [if] responsive to the assigned DVCC is not detected; and terminating the communication (322) [if] when the bad slot counter reaches a predetermined maximum value. A good slot counter is incremented (310) when the assigned DVCC is detected in a burst. The good slot counter is reset (318) [if] when the assigned DVCC is not detected in the next burst, and both counters are reset (314) [if] when the assigned DVCC is detected in consecutive bursts.
