Adaptive Registration Area Adjustment for Wireless Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional registration methods in wireless communication systems are inefficient for mobile access terminals, as they require frequent registrations to conserve power, leading to increased network resources for paging, which is not optimal for mobile devices.
Innovation Solution
The system adaptively adjusts the registration and paging areas by determining if a registration is required, performing registrations, and generating new registration areas based on the access terminal's location, using either base station coverage or distance-based methods to minimize unnecessary registrations and optimize paging resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If registration frequency is reduced to conserve power, then power consumption decreases, but the network must increase paging resources to locate mobile terminals
Solution Approach 1:
The patent implements dynamic adjustment of registration area size based on terminal mobility characteristics. The system transitions from static registration areas to adaptive registration areas that expand or contract based on observed terminal movement patterns, allowing reduced registration frequency for mobile terminals while maintaining effective paging coverage
Solution Approach 2:
The system changes the parameter of registration area size dynamically. By adjusting the registration area radius based on terminal mobility data, the network can accommodate longer registration intervals for mobile terminals without proportionally increasing paging overhead, as the expanded registration area pre-covers potential terminal locations
2Productivity
If registration area is expanded to reduce registration frequency, then power consumption decreases, but paging area increases requiring more network resources
Solution Approach 1:
The patent segments the network into multiple registration areas of varying sizes based on terminal mobility patterns. Rather than using a single large paging area, the system creates hierarchical registration areas that can be selectively expanded or contracted, allowing efficient resource allocation across different geographic regions
Solution Approach 2:
The registration area size is made dynamic rather than static. The system adjusts registration area boundaries based on real-time terminal mobility observations, expanding areas for highly mobile terminals and maintaining smaller areas for stationary terminals, thereby optimizing both registration frequency and paging resource usage
3Adaptability or versatility
If adaptive registration is implemented for mobile terminals, then power consumption and network resources are optimized, but system complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where terminal mobility patterns are monitored and used to dynamically adjust registration area sizes. The system collects mobility data, analyzes movement patterns, and automatically adjusts registration parameters, creating a self-optimizing system that adapts to terminal behavior without manual intervention
Solution Approach 2:
The system performs self-adjustment of registration parameters based on observed terminal patterns. Rather than requiring manual configuration or complex centralized control, the network autonomously modifies registration area sizes and intervals based on terminal mobility characteristics, reducing operational complexity

AI summary
Accordingly, a method adaptive registration is disclosed, wherein the access terminal adjusts the registration area based on mode and its location. Accordingly, the network also adjusts its paging area. Generally, the access terminal will transition from small registration area to large registration area based on its mobility.
