Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G systems face challenges in efficiently managing location services and handovers, particularly in selecting the appropriate location management components (LMCs) for wireless devices, which can impact network performance and user experience.
Innovation Solution
Implementing a system that enables the selection of a location management component (LMC) based on positioning capabilities and types, allowing for optimized LMC determination and communication with base stations to enhance location management in 5G systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a centralized location management approach is used in 5G systems, then location services can be provided, but the system complexity increases and handover efficiency decreases
Solution Approach 1:
The patent divides the centralized location management function into distributed Location Management Components (LMCs) deployed at different base stations. Each LMC handles location management for devices in its local area, segmenting the monolithic centralized system into smaller autonomous units that reduce overall system complexity while maintaining location service capabilities.
Solution Approach 2:
The patent introduces a new dimensional approach by deploying LMCs across multiple spatial dimensions (different base stations and geographic areas) rather than relying on a single centralized point. This distributed spatial arrangement enables parallel location management operations, reducing complexity and improving handover efficiency through localized decision-making.
2Ease of operation
If location management is handled by a single centralized component, then system control is simplified, but handover performance and location accuracy deteriorate
Solution Approach 1:
The patent segments the single centralized location management role into multiple distributed LMCs, where each LMC is responsible for a specific geographic area or base station. This segmentation maintains operational simplicity through standardized LMC interfaces while improving handover performance by enabling localized, real-time location management decisions at each distributed point.
3Measurement precision
If LMC selection is based on comprehensive positioning capabilities, then location service accuracy improves, but the time required for LMC determination increases
Solution Approach 1:
The patent implements preliminary action by having LMCs pre-register their positioning capabilities and availability status with the network before actual location management is needed. When a device requires location services, the network can quickly determine the appropriate LMC based on pre-collected capability information, reducing selection time while maintaining accurate positioning based on the pre-registered capabilities of suitable LMCs.

AI summary
A second access and mobility management function (AMF) may receive a first message having positioning capability information indicating that a location management component (LMC) supports one or more positioning types. The second AMF may receive, from a first AMF, a second message indicating a positioning type of a wireless device. The second AMF may determine the LMC based on the positioning type and the positioning capability information. The second AMF may send, to a base station associated with the LMC, a third message having an identifier of the LMC.
