Quick Page Message Structure for False Wake-Up Reduction
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
The implementation of a method to form a quick page message with a set structure that minimizes false wake-ups by utilizing partial identity comparison, where the length and configuration of page identifier sets are optimized based on the number of access terminals being paged, allowing for unequal bit allocations and redundancy removal to fully utilize available bits, thereby reducing the likelihood of false wake-ups.

1Use of energy by moving object
If partial hash comparison scheme is used for quick paging, then battery consumption is reduced, but false wake-up probability increases when paging load is high
Solution Approach 1:
The patent segments the access terminal identifier into multiple parts and compares them in stages. The quick page message includes a first part of the identifier for initial comparison, and upon match, a second part is compared. This segmentation allows the access terminal to wake up fully only when necessary, reducing false wake-ups while maintaining low power consumption during the initial partial comparison phase.
Solution Approach 2:
The patent implements dynamic adjustment of the quick page message structure based on the number of access terminals being paged. When fewer terminals are paged, a more compact structure with fewer bits is used. When more terminals are paged, the structure expands to include additional bits. This dynamic adaptation optimizes the balance between false wake-up probability and power consumption under varying load conditions.
2Use of energy by moving object
If quick page message structure is simplified, then power consumption is reduced, but paging capacity decreases
Solution Approach 1:
The patent employs dynamic structure adjustment where the quick page message length and configuration change based on the number of access terminals to be paged. The system adapts the message structure to match the actual paging load, using minimal bits when few terminals need paging and expanding capacity when more terminals are involved, thereby optimizing both power consumption and paging capacity under different conditions.
Solution Approach 2:
The patent applies different bit allocations to different parts of the identifier based on their importance and the number of terminals being paged. More significant bits are allocated to portions of the identifier that distinguish between more access terminals, while less significant bits receive fewer allocations. This local optimization of quality allows efficient use of available bits to maximize paging capacity without unnecessary power consumption.

AI summary
Apparatus, and an associated method, for facilitating paging of an access terminal operable in a radio communication system. A paging message is formed, selectably including partial identities of access terminals that are to be paged by the paging message. Determination is made as to whether portions of any of the partial identities have portions of common values. If portions of the partial identities have common values, such portions can be shared, and extra parts, resulting from sharing can be reallocated to increase the length of another partial identity.
