Network Element Location Verification for UE Paging Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in accurately determining the current location of user equipment (UE) for constructing registration areas, paging ranges, and managing mobility, which can lead to inefficiencies and increased paging loads.
Innovation Solution
Implementing methods in network elements to determine whether received location information represents the current or proximity location of UE, using distinct fields or indication information to confirm accuracy, thereby enhancing the construction of registration areas and paging ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If location information is used to construct registration areas and paging ranges, then mobility management efficiency is improved, but location accuracy cannot be guaranteed leading to spoofing behaviors
Solution Approach 1:
The patent applies preliminary action by having the second network element determine whether location information represents current location before transmitting it to the first network element. This advance verification prevents inaccurate location data from being used in registration area construction and paging range determination, thereby eliminating spoofing behaviors while maintaining mobility management efficiency.
2Loss of information
If location information is transmitted without verification, then signaling overhead is reduced, but registration area construction accuracy deteriorates
Solution Approach 1:
The patent segments the location information transmission process into two distinct parts: (1) the second network element performs local determination of whether location information represents current location, and (2) the first network element uses this verified information for registration area construction. This segmentation allows for accurate registration area construction while minimizing signaling overhead by only transmitting the determination result rather than raw location data.
3Productivity
If location information is used for paging, then paging load is reduced, but location spoofing increases
Solution Approach 1:
The patent implements feedback by having the second network element provide determination results about location information authenticity to the first network element. This feedback mechanism ensures that only authenticated location data is used for paging operations, thereby maintaining both high paging efficiency and location authenticity, and preventing spoofing while reducing paging load.
