Paging Control Apparatus for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, existing paging methods are inefficient for low-mobility wireless terminals, as they often result in increased paging load and potential paging failures due to the use of large geographical paging areas, which are not tailored to the specific mobility characteristics of these terminals.
Innovation Solution
The mobility management node determines a paging area based on the external network with which the wireless terminal communicates, using identification information such as APN, to adjust the geographical coverage according to the terminal's mobility level, thereby optimizing the paging area for low-mobility terminals by reducing the geographical extent when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large geographical paging area is used for all wireless terminals, then paging coverage is ensured, but paging load increases and paging failures occur for low-mobility terminals
Solution Approach 1:
The patent applies local quality by differentiating paging area determination based on terminal mobility characteristics. Low-mobility terminals are assigned smaller paging areas while high-mobility terminals use larger paging areas, optimizing resource allocation for each category rather than using a uniform approach for all terminals.
Solution Approach 2:
The patent implements dynamics by making paging area size adaptable to terminal mobility behavior. The system dynamically adjusts paging area configuration based on whether terminals are low-mobility or high-mobility, allowing the paging structure to respond to changing conditions rather than remaining static.
2Reliability
If a large geographical paging area is used, then paging coverage is maintained, but paging efficiency decreases for low-mobility terminals
Solution Approach 1:
The patent applies local quality by differentiating paging area determination based on terminal mobility characteristics. Low-mobility terminals are assigned smaller paging areas while high-mobility terminals use larger paging areas, optimizing resource allocation for each category rather than using a uniform approach for all terminals.
Solution Approach 2:
The patent implements parameter changes by modifying the paging area size parameter according to terminal mobility characteristics. The system changes the geographical extent of paging areas based on whether terminals are low-mobility or high-mobility, optimizing the balance between coverage and efficiency for different terminal types.
3Productivity
If identification information such as APN is used to determine paging area, then paging area can be optimized for low-mobility terminals, but system complexity increases
Solution Approach 1:
The patent applies self-service by utilizing identification information (such as APN) that is already available in the system to automatically determine terminal mobility characteristics and configure appropriate paging areas. The system uses existing data resources to perform the optimization without requiring additional complex measurement or signaling mechanisms.
