Positioning Server Capability Exchange for Integrity-Based Error Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning technologies fail to reduce positioning errors to meet quality of service (QoS) requirements, particularly in critical scenarios involving safety and legal liability, leading to potential serious consequences.
Innovation Solution
A capability obtaining and sending method involving a positioning server and device that includes obtaining and sending integrity capability information to support integrity features, such as monitoring, evaluation, and correction of positioning operations using various positioning manners and reference signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning service accuracy meets QoS requirements, then positioning service quality is improved, but positioning error may still be extremely large in critical scenarios
Solution Approach 1:
The patent applies preliminary action by obtaining integrity capability information from the first device before performing positioning operations. The positioning server proactively requests and stores integrity capability information (including supported positioning manners and reference signals) in advance, enabling subsequent integrity-based positioning error control without delaying the positioning service flow.
Solution Approach 2:
The patent implements feedback through the integrity capability information exchange between positioning server and first device. The server obtains capability information from the device, uses it to select appropriate positioning methods, and can subsequently provide positioning correction information back to the device, forming a closed-loop feedback mechanism for error control.
2Reliability
If integrity capability information is obtained and processed, then positioning reliability is improved, but system complexity increases
Solution Approach 1:
The patent applies the extraction principle by isolating integrity capability information as a separate, structured data element. The capability information is extracted from the positioning protocol and organized into distinct fields (supported positioning manners, supported reference signals), allowing the server to process only the necessary integrity-related parameters without handling entire positioning messages.
Solution Approach 2:
The patent implements universality by designing the integrity capability information structure to serve multiple functions: it indicates supported positioning manners, identifies supported reference signals, and enables integrity-based error control. This multi-functional capability information reduces the need for separate protocol elements for each function.
