Access Terminal Sector List Paging Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face inefficiencies in locating access terminals due to high system overhead from paging messages, as existing methods like subnet-based and radius-based paging consume significant resources and result in inaccurate location estimation and increased power consumption.
Innovation Solution
Access terminals collect and provide sector lists indicating likely locations based on usage patterns, allowing for reduced unnecessary route updates and targeted paging messages, thereby optimizing resource usage and location accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the wireless communication system transmits paging messages to a large number of cells to locate the access terminal, then the location accuracy is improved, but the system overhead increases
Solution Approach 1:
The access terminal collects and provides sector list information in advance, enabling the network to perform targeted paging only in relevant sectors rather than broadcasting to all cells. This preliminary information gathering reduces the need for extensive paging operations while maintaining accurate location tracking.
Solution Approach 2:
Instead of uniform paging across all cells, the system uses sector-specific information to apply localized paging only where the access terminal is likely to be found. This targeted approach concentrates resources on relevant areas, reducing overall system overhead while maintaining location accuracy.
2Measurement precision
If the access terminal transmits route update messages frequently to improve location accuracy, then the location estimation accuracy is improved, but the power consumption increases
Solution Approach 1:
The access terminal collects sector information in advance and provides it to the network, enabling accurate location tracking without requiring frequent route update transmissions. This preliminary information provision reduces the frequency of power-consuming transmissions while maintaining location accuracy.
Solution Approach 2:
The access terminal autonomously collects and manages its own sector list information, providing this data to the network to enable efficient location tracking. This self-service approach reduces the need for continuous network-requested updates, thereby reducing power consumption while maintaining accurate location information.
3Quantity of substance
If the wireless communication system uses subnet-based paging to reduce paging load, then the paging overhead is reduced, but the location accuracy deteriorates
Solution Approach 1:
The system segments the paging approach by using sector-level granularity instead of subnet-level granularity. The sector list provided by the access terminal enables paging to be performed at a more fine-grained level, reducing the number of cells that need to be paged while improving location accuracy compared to subnet-based approaches.
Solution Approach 2:
Instead of using coarse subnet-based paging, the system applies localized sector-specific paging based on the access terminal's provided sector list. This local quality approach targets paging messages to specific sectors rather than broad subnets, reducing paging overhead while improving location accuracy.

AI summary
The present invention provides a method including providing at least one route update message based upon at least one sector list associated with an access terminal. The sector lists are formed based on information collected by the access terminal. Paging is also done according to the sector list.
