Abstract
A method for synchronizing counters in a wireless terminal device with those of an administrative device. With each increment of the frame counter in a wireless terminal device, the wireless device minislot counter advances by an amount equal to the number of minislots per frame. Likewise, with each increment of the frame counter, the wireless device's timestamp counter is incremented by the number of timestamps per frame. This continues until the counters at the wireless device are within one frame of the administrative device's counters. The minislot counter is then incremented. With each increment of the minislot counter, the timestamp counter is incremented by an amount equal to the number of timestamps per minislot. This continues until the wireless devices counters are within a minislot of the administrative device's counters. The timestamp counter is then incremented until the wireless device's counters match those of the administrative device.
