Variable Bit Length Page Messages for False Wakeup Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current quick paging systems in radio communication systems face challenges in minimizing false wakeups of access terminals, leading to excessive battery depletion, especially when paging multiple terminals, and are inefficient in utilizing available bits in page messages.
Innovation Solution
The system optimizes quick page messages by varying the bit lengths of partial identities to create redundant values, allowing for their removal and reallocation to increase the bit lengths of remaining identities, thereby reducing the likelihood of false wakeups and improving battery longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bit length of partial identities in page messages is increased to reduce false wakeups, then the reliability of paging is improved, but the quantity of information that can be transmitted in the page message decreases
Solution Approach 1:
The patent dynamically adjusts the bit length parameter of partial identities based on the number of terminals being paged. When fewer terminals are paged, longer bit lengths are used to reduce false wakeups. When more terminals are paged, shorter bit lengths are used to accommodate more identities. This parameter adaptation resolves the contradiction between reliability and quantity.
Solution Approach 2:
The page message structure is made dynamic by allowing the bit length of partial identities to vary rather than being fixed. The system adapts the identity structure in real-time based on paging conditions, enabling optimal balance between reducing false wakeups and accommodating multiple terminals in the same page message.
2Device complexity
If uniform bit lengths are used for all partial identities, then the device complexity is reduced, but the productivity of bit utilization decreases
Solution Approach 1:
Instead of applying a uniform bit length to all partial identities, the patent applies different bit lengths to different identities based on local requirements. Each partial identity's bit length is optimized according to its specific position and the overall paging scenario, maximizing bit utilization while maintaining manageable complexity through structured variation.
3Reliability
If more bits are allocated to partial identities to reduce false wakeups, then the probability of false wakeup decreases, but the available bits for other page message components decrease
Solution Approach 1:
The patent makes the bit allocation dynamic by adjusting the number and length of partial identities based on the actual number of terminals being paged. This dynamic allocation ensures that sufficient bits are available for both reducing false wakeups and accommodating other necessary page message components such as padding and structure fields.

AI summary
Apparatus and an associated method is provided for facilitating paging of an access terminal in a radio communication system. A page message with partial identities is generated that includes an access sequence ID. The access sequence ID is used by the access terminal when responding to a page. The access terminal sends an access probe using the access sequence ID included in the page. The page message includes a message structure with partial identities where the access sequence ID is conditionally included. If the access terminal is to use a regular pool of access sequence IDs, the access terminal is not sent an access sequence ID in the page.
