Abstract
Methods, devices and computer program products are disclosed that allow for wireless communication devices to operate more robustly in the slotted mode of operation in the event of network system loss. Specifically, present aspects require the wireless device to move to or remain in the slotted mode of operation as opposed to immediately entering into a system determination/acquisition mode upon failing to acquire an active set pilot during a slotted wake-up. By moving to the slotted mode of operation or providing for additional slotted-wake-ups, a number of attempts at acquiring the active set pilot can be performed before declaring the system as lost, thereby allowing for fading channel conditions to prevail without the need to re-acquire the lost system or otherwise acquire another system. Since the performance of the slotted mode is less power intensive than acquiring or re-acquiring a system, a substantial power savings is realized.
