Partial Identity Comparison for Paging Message Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing partial hash comparison scheme in radio communication systems is less effective in reducing false wakeups of access terminals when the paging load is high, leading to reduced battery longevity and inefficient use of bit locations in quick page messages.
Innovation Solution
The proposed solution involves a partial identity comparison scheme that optimizes the length and arrangement of access terminal identifiers in quick page messages, using determiners and redundant page value removers to minimize redundant values and maximize bit usage, thereby reducing false wakeups and improving battery longevity.

Engineering Contradiction Analysis
1Duration of action of stationary object
If partial hash comparison scheme is used to reduce false wakeups, then battery longevity is improved, but the scheme becomes less effective when paging load is high
Solution Approach 1:
The patent changes the parameter of identifier length dynamically. When paging load is low, shorter identifiers are used; when paging load is high, longer identifiers are used. This adaptive parameter change allows the system to maintain low false wakeup rates across varying traffic conditions while optimizing battery longevity.
Solution Approach 2:
The system dynamically adjusts the paging message structure based on current load conditions. The access terminal and network cooperate to determine the optimal identifier length in real-time, making the paging mechanism adaptive rather than static. This resolves the contradiction by allowing the system to optimize for battery longevity during low-load periods while maintaining reliability during high-load periods.
2Reliability
If more bit locations are used for identifier comparison, then false wakeup reduction is improved, but bit usage efficiency decreases
Solution Approach 1:
The patent implements variable-length identifiers that adapt to the number of terminals being paged. When few terminals are paged, shorter identifiers are used, maximizing bit usage efficiency. When many terminals are paged, longer identifiers are used, improving false wakeup reduction. This parameter adaptation resolves the contradiction between reliability and bit efficiency.
3Device complexity
If fixed-length identifiers are used in quick page messages, then message structure is simplified, but redundancy cannot be eliminated
Solution Approach 1:
The patent transitions from fixed-length to variable-length identifiers. The system dynamically determines the optimal identifier length based on the specific paging scenario, allowing the message structure to adapt rather than remain rigid. This dynamic approach eliminates redundancy when possible while maintaining structural simplicity through automated length determination.

AI summary
Apparatus, and an associated method, for facilitating access terminal paging. A first non common portion of first and second identities are ordered. Once ordered, the non common portions are included in an access terminal paging message. The ordering of the non common portions are determinative of conveyance of a first additional identity bit.
