Shared Positioning Server for Roaming Terminal Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminal positioning systems face challenges in providing accurate positioning services when there is no position calculation system available in the network, leading to service failures or reliance on external networks, and accuracy issues when roaming across different networks.
Innovation Solution
A positioning apparatus and method utilizing a positioning server independently constructed on a network to collect and manage assistant data, allowing for shared positioning services across multiple networks, separating positioning service permission and calculation modules to enable accurate positioning with reduced implementation costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a positioning server is independently constructed on each network, then positioning accuracy for roaming terminals is improved, but implementation costs and system complexity increase
Solution Approach 1:
The patent applies universality by enabling a positioning server constructed on one network to provide positioning services to multiple networks including roaming networks. The positioning server collects assistant data from multiple sources and serves multiple networks, eliminating the need for each network to independently construct its own positioning server while maintaining positioning accuracy for roaming terminals.
2Reliability
If a positioning server is independently constructed on each network, then positioning service reliability is improved, but implementation costs increase
Solution Approach 1:
The patent applies merging by consolidating positioning server functions into a shared infrastructure that serves multiple networks. Instead of each network deploying separate positioning servers, the system merges positioning capabilities into a common platform that can be accessed by multiple networks, reducing implementation costs while maintaining service reliability through centralized management and resource optimization.
3Adaptability or versatility
If external positioning systems are used when no position calculation system is available, then service coverage is improved, but positioning accuracy deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-collecting and storing assistant data (including satellite orbit information and correction information) in a database before positioning requests arrive. When a positioning request is received, the system can immediately retrieve pre-prepared assistant data and perform rapid position calculations, ensuring both wide service coverage and high positioning accuracy without relying on external positioning systems.

AI summary
A positioning apparatus and method of a mobile terminal using a positioning server independently constructed on a network. The positioning apparatus includes a positioning server, independently constructed on a network, for collecting and storing/managing assistant data that includes orbit information and correction information of a satellite, and providing the assistant data or position information using the assistant data in response to an external request. The positioning server provides the position information of the terminal subject to positioning in response to the request for the position information of the terminal subject to positioning created from at least one network among a plurality of networks that share the positioning server. Accordingly, an accurate positioning result can be obtained with a cost for implementation of the positioning system reduced.
