Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick paging schemes in radio communication systems, particularly using partial hash comparison, face increased false wake-up probabilities when the paging load is high, leading to reduced battery longevity in access terminals.
Innovation Solution
A method and apparatus that form a quick page message with a partial identity scheme, utilizing selected significant bits of access terminal identifiers, and a redundant page value remover to eliminate redundant values, allowing for efficient identification of multiple access terminals and reducing false wake-ups.

1Use of energy by moving object
If partial hash comparison is used for quick paging, then battery consumption is reduced and battery longevity is improved, but false wake-up probability increases when paging load is high
Solution Approach 1:
The access terminal identifier is divided into multiple segments: a first portion (e.g., 5-10 most significant bits) is placed in the quick page message for partial comparison, while the remaining portion is reserved for full identity verification. This segmentation allows the terminal to perform quick partial matching to filter out non-matching pages, reducing false wake-ups while maintaining low battery consumption.
Solution Approach 2:
Instead of performing complete identity comparison for every page message, the system performs partial comparison using only the first portion of the identifier. This partial action is sufficient to eliminate obvious non-matches quickly, while full comparison is performed only when necessary, optimizing the balance between reliability and energy consumption.
2Reliability
If quick page message length is increased to include more identifier information, then false wake-up probability decreases, but message overhead and processing complexity increase
Solution Approach 1:
The identifier comparison process is segmented into two stages: first, quick comparison of the first portion (5-10 bits) embedded in the page message; second, full comparison of the remaining portion only for matching candidates. This reduces message overhead while maintaining high reliability through staged verification.
Solution Approach 2:
The system performs preliminary filtering using the first portion of the identifier before committing to full identity verification. This preliminary action eliminates most non-matching pages early, reducing the need for lengthy messages and simplifying overall processing complexity.
3Productivity
If more access terminals are paged simultaneously, then system capacity is improved, but false wake-up probability increases with existing schemes
Solution Approach 1:
The identifier space is segmented such that the first portion (5-10 bits) provides coarse-grained filtering capability. When multiple terminals are paged, this segmentation allows efficient differentiation even with limited message length, enabling high system capacity while maintaining low false wake-up rates through the two-stage comparison process.

AI summary
Apparatus, and an associated method, for facilitating paging of access terminals by way of a quick page message. A partial identity comparison scheme is utilized. Identifiers of access terminals that are to be paged in the quick page message are determined and compared. In the event that the identifiers are of redundant values, the redundant values are removed, thereby to provide additional locations in the quick page message that are not redundant for use better to page the access terminals that are to be paged.
