REDUCED SCANNING WITHIN A UNIFORM PERIOD IN OUT-OF-SERVICE CONDITIONS
First Claim
1. A method for reduced scanning within a uniform period in an out-of-service condition, comprising:
- detecting the out-of-service condition;
during a wake-up interval, waking up to scan one or more channels for service;
maintaining a constant wake-up time for subsequent wake-up intervals; and
varying the amount of time spent scanning the channels during the subsequent wake-up intervals.

Abstract
A method (300) and mobile device (120) for reduced scanning within a uniform period in an out-of-service condition is described herein. In one arrangement, the method can include the steps of detecting (310) the out-of-service condition, during a wake-up interval (410), waking (314) up to scan one or more channels (510, 520, 530, 540) for service and maintaining a constant wake-up time for subsequent wake-up intervals. The method can also include the step of varying (320) the amount of time spent scanning the channels during the subsequent wake-up intervals. As an example, varying the amount of time spent scanning channels can be done by decreasing (322) the amount of time spent scanning for each successive, subsequent wake-up interval.

9. A mobile device that reduces scanning within a uniform period in an out-of-service condition, comprising:
-
a transceiver that receives wireless signals from a communication network; and a processor that is coupled to the transceiver, wherein the processor; detects that the transceiver is in the out-of-service condition with the communication network; determines a wake-up interval and a constant wake-up time for the transceiver such that the transceiver will wake up on a substantially uniform basis to scan one or more channels for service; and varies the amount of time that the transceiver will spend scanning the channels for subsequent wake-up intervals. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A machine readable storage having stored thereon a computer program having a plurality of code sections executable by a mobile device for causing the mobile device to perform the steps of:
-
detecting an out-of-service condition at the mobile device; determining a wake-up interval for the mobile device; during the wake-up interval, waking up the mobile device to scan one or more channels for service; maintaining a uniform wake-up time for the mobile device for subsequent wake-up intervals; and varying the amount of time that the mobile device spends scanning the channels for service during the subsequent wake-up intervals. - View Dependent Claims (18, 19, 20, 21)

22. A method of reduced scanning, comprising:
-
in response to an out-of-service condition, determining a wake-up interval that designates when a mobile device will wake-up at a uniform rate; when the mobile device wakes up, scanning one or more channels of a scan list for service; and reducing the amount of time that the mobile device spends scanning the scan list for each successive wake-up interval until fixed minimal scanning time is reached, while maintaining the uniform wake-up rate of the mobile device.
