1. A method to manage processing operations following a wireless terminal receiving a null page from a servicing base station, the method comprises:
- receiving an encoded paging burst on a paging channel;
decoding the encoded paging burst to produce a decoded paging burst;
determining that the decoded paging burst contains a null page for the wireless terminal;
consolidating a plurality of staggered processing operations associated with receiving a plurality of subsequent encoded paging bursts when the decoded paging burst contains the null page for the wireless terminal;
performing the consolidated plurality of staggered processing operations as a group following the null page; and
after the consolidated plurality of staggered processing operations is performed during an awake period, entering a sleep mode for a sleep mode period that is adjacent to and follows the awake period; and
after receipt of one of the plurality of subsequent encoded paging bursts during a subsequent awake period, entering a subsequent sleep mode period that is adjacent to and follows the subsequent awake period, wherein a length of the subsequent sleep mode period is longer than a length of the sleep mode period and a length of the subsequent awake period is shorter than a length of the awake period.

Abstract
A method and system to determine when a wireless terminal has been paged by a servicing base station. An encoded paging burst is received on a paging channel and then decoded to produce a decoded paging burst. The decoded paging burst is processed to determine if it is a null page. When the encoded paging burst is a null page, subsequent processing operations scheduled to follow a later null page are rescheduled and immediately processed, allowing the wireless terminal to re-enter the sleep mode more quickly following the receipt of a subsequent paging burst.
