Abstract
A power management system for a mobile unit wherein the frequency of detecting a paging message may be controlled. The quality of the signal transmitted by a base station and the acceptable delay are determined by the mobile unit. The mobile unit compares these factors to the current paging message monitoring rate. If a further delay is acceptable, the present invention inhibits monitoring of at least one cycle of the paging message. Each cycle of the paging message inhibited conserves battery power in the mobile unit. The mobile unit also includes a technique for the user to disable the power savings feature.
