Abstract:
In a reverse link of a wireless CDMA communication system, a method of maintaining an idling mode connection between a field unit and a base transceiver station is provided using various techniques to maintain the idle mode connection at a reduced power level. A preferred embodiment computes a time slot or frame offset based on modulo function using a field unit identifier in order to distribute field unit maintenance transmissions among available slots or offsets. An alternate embodiment detects explicit signaling states changes at the physical layer and causes power target changes. A further embodiment transmits maintenance data during predetermined time intervals, coordinated between the field units and BTS, allowing power levels to be adjusted accordingly.
