Rapid Paging Mechanism for Wireless Device Location Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular wireless communication systems, zone-based paging often wastes network resources by broadcasting page messages in all sectors of a device's last registration zone, even if the device is already in a different sector where the initial page was successful, leading to potential delays and increased resource usage.
Innovation Solution
Implementing a 'rapid page' mechanism that targets the specific sector where the mobile device is believed to be located, based on its mobility indicators and the mobility characteristics of its last-known coverage area, before initiating zone-based paging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If zone-based paging is used to page a wireless communication device, then the paging coverage is ensured across all sectors in the device's registration zone, but network resources are wasted by broadcasting page messages in sectors where the device is not located
Solution Approach 1:
The patent applies local quality by differentiating paging actions based on the specific sector where the device is most likely located. Instead of uniform paging across all zones, the system concentrates paging resources in the specific sector identified through mobility analysis, making the paging quality local rather than uniform across the entire zone.
Solution Approach 2:
The patent changes the paging parameter from a static zone-based approach to a dynamic sector-specific approach. By analyzing device mobility patterns and determining the most probable sector, the system adapts the paging location parameter to match the device's likely position, thereby reducing unnecessary broadcasts in other sectors while maintaining reliable coverage.
2Reliability
If zone-based paging is used to ensure comprehensive coverage, then the device will be paged successfully even if it has moved to a different sector, but paging delays increase due to broadcasting in multiple sectors
Solution Approach 1:
The patent applies preliminary action by performing mobility analysis and determining the most likely device sector before initiating the paging process. This advance preparation allows the system to target the paging message to the correct sector from the outset, eliminating the sequential delays that would occur with multi-sector broadcasting while maintaining high success rates.
Solution Approach 2:
The patent substitutes the mechanical sequential broadcasting process with an intelligent targeting system. Instead of physically broadcasting to all sectors in sequence, the system uses mobility pattern analysis to calculate and directly target the most probable sector, replacing the brute-force mechanical approach with a computational intelligence approach that reduces time while maintaining reliability.
3Loss of energy
If rapid page targeting is used to reduce resource usage, then network resources are optimized by paging only in the most likely sector, but paging reliability decreases if the device has moved to a different sector
Solution Approach 1:
The patent applies feedback by continuously monitoring device mobility patterns and using this information to dynamically adjust paging decisions. The system incorporates feedback from historical mobility data, current location information, and device behavior patterns to make informed targeting decisions, thereby maintaining high reliability while optimizing resource usage through precise sector selection.
4Measurement precision
If mobility indicators are analyzed to determine rapid page targeting, then paging accuracy is improved by identifying the most likely device location, but system complexity increases due to additional analysis requirements
Solution Approach 1:
The patent applies universality by designing the mobility analysis system to serve multiple functions simultaneously. The same mobility indicators and analysis mechanisms are used not only for rapid page targeting but also for general device tracking, location management, and network optimization purposes. This multi-functionality reduces the need for separate complex systems while improving location accuracy for paging decisions.

AI summary
Disclosed herein are exemplary methods and systems that may help determine when to make a rapid page attempt in a certain coverage area, before resorting to zone-based paging. An exemplary method involves: (a) at a radio access network, determining that a wireless communication device (WCD) should be paged; (b) responsive to determining that the WCD should be paged: (i) determining a last-known coverage area of the WCD, (ii) based at least in part on a WCD mobility indicator of the WCD and a coverage-area mobility indicator of the last-known coverage area, determining an overall mobility indicator, and (iii) using the overall mobility indicator as a basis for determining whether or not to make a rapid page attempt to the WCD; (c) if it is determined to make the rapid page attempt, then making the rapid page attempt in the last-known sector; and (d) otherwise, using a zone-based paging scheme to page the WCD.
