Embodiment Construction

[0020] A detailed description of a method and system having multiple decision levels for determining the presence of a paging indicator in a wireless communication system is provided below. The subject matter set forth herein is applicable to wireless communication systems that multiplex signals using time division multiplexing (TDM), code division multiplexing (CDM), and frequency division multiplexing (FDM) techniques. For illustration purposes, a CDMA2000 system is used as an example.

[0021] In a wireless communication system such as a CDMA2000 system, multiple paging indicators are implemented. Those skilled in the art understand that a paging indicator is a signal used to detect the presence of a paging signal, and is broadly defined including, but not limited to, the following paging indicator examples. For example, the quick paging channel paging indicator is designed for a paging channel (Paging Channel, PCH). Another quick paging channel configuration change indic...

Abstract

A method and system is disclosed for detecting paging indicators using a multi-stage and multi-threshold detection mechanism so that a mobile terminal can be removed from an idle mode appropriately. After receiving a first paging indicator, it is determined whether a first indicator measurement corresponding to the first paging indicator is between a first and a second predetermined thresholds. After receiving a second paging indicator which may be a temporal diversity counterpart of the first paging indicator, a second indicator measurement derived based on both the first and second paging indicators is compared against a third predetermined threshold, wherein the mobile terminal is removed from the idle mode when both comparisons are appropriately conducted.

Description

technical field [0001] The present invention relates generally to a wireless communication system, and more particularly to a method and system for detecting the presence of a paging indicator in a wireless communication signal. Background technique [0002] In wireless communication systems, when there are neither voice nor data calls, a mobile terminal remains in an idle mode to conserve battery power. In idle mode, the mobile terminal periodically wakes up for a short period of time (typically on the order of milliseconds) to monitor the paging indicator to detect whether the mobile terminal is paged. A relatively simple predetermined algorithm is typically used to determine whether the paging indicator indicates that there is an ongoing or up-and-coming voice or data call. If the result of the predetermined algorithm is positive, the mobile terminal is woken up to decode the information communicated over the normal channel, which information may include dedicated or bro...
