LTE Positioning QoS Discrimination via Extended Service Types
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current positioning technologies in LTE lack flexibility and precision in handling various commercial location-based services, with limited QoS discrimination and client/service type definitions, leading to suboptimal positioning sequences for different service requirements.
Innovation Solution
Extending the number of client and service types, and configuring network nodes to understand these extended definitions, allowing for signaling of specific positioning sequences that match the QoS criteria of each type, enhancing measurement quality and adaptability in UE-assisted or network-based positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of client and service types is extended to provide richer QoS discrimination, then positioning accuracy and service adaptability improve, but system complexity and configuration difficulty increase
Solution Approach 1:
The patent segments the positioning system into distinct client types (e.g., emergency services, value-added services, operator services) and service types (e.g., single-shot positioning, periodic positioning, trigger-based positioning). Each segment has predefined QoS parameters and positioning sequence configurations, allowing precise control over positioning accuracy for different services while managing complexity through modular organization.
Solution Approach 2:
The patent introduces multiple QoS parameters (response time, accuracy code, vertical accuracy code, positioning priority) that can be adjusted independently for different client and service types. By changing these parameters, the system can optimize positioning accuracy and response characteristics without redesigning the entire system architecture.
2Productivity
If positioning sequences are tailored to specific service requirements, then service quality and response time improve, but configuration and management complexity increase
Solution Approach 1:
The patent pre-configures positioning sequences and QoS parameters for different client and service types during system setup or through operator provisioning. Common positioning scenarios (emergency, commercial LBS, operator services) have predetermined configurations stored in the network nodes, eliminating the need for complex real-time configuration decisions and simplifying operational management.
Solution Approach 2:
The patent creates a universal positioning framework where a single configuration mechanism handles multiple service types and client categories. The same signaling infrastructure and QoS parameter set apply across all positioning scenarios, allowing the system to manage diverse positioning requirements through a unified configuration approach rather than separate specialized systems.
3Reliability
If QoS discrimination is enhanced with more client and service types, then service differentiation and positioning quality improve, but signaling overhead and processing load increase
Solution Approach 1:
The patent merges QoS parameter signaling with existing positioning request messages in the LTE network. Rather than introducing separate signaling channels for QoS information, the QoS parameters (response time, accuracy codes, priority) are embedded within standard positioning protocol messages such as LPP (LTE Positioning Protocol) and LCS-AP (Location Services Application Protocol), reducing additional signaling overhead while maintaining comprehensive QoS discrimination.

AI summary
One aspect of the present invention extends the number of client and/or service types used in location-based services. The extension provides richer definitions for use in selecting the optimal or otherwise best suited positioning sequences to be used in fulfilling given positioning requests. For example, some types of commercial-related positioning requests are better satisfied with quicker-but-lower-accuracy position determinations, while other types benefit from more-accurate-but-slower position determinations. These and other benefits are provided by extending the type definitions used to identify commercial positioning requests. For example, a UE may be configured to send positioning requests that indicate the extended client or service types. As another example, the network node(s) involved in generating or processing such requests are configured to understand the extended type definitions and/or to map the extended definitions to QoS requirements, or to particular positioning sequences, for requesting that a positioning node carry out that particular positioning sequence.
