Abstract
The time division multiple access (TDMA) frame time synchronization error for received mobile station burst communications transmitted on the reverse digital control channel is monitored by the receiving base station. A probability density function is then prepared by the base station reflecting the number of instances of each determined length of time synchronization error monitored over a predetermined time period. The probability density function is then processed to identify the percentage of burst communications during that predetermined time period that exceed a synchronization error threshold. If the determined percentage exceeds a given percentage, then abbreviated length burst communication operating mode is ordered by the base station for all mobile stations operating within the cell. Otherwise, conventional length burst communication operating mode is ordered by the base station. The measured time synchronization error is continuously processed to effectuate dynamic control over the specified length of mobile station burst communications.
