SUPL Location Platform Independent Positioning Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face inconvenience in updating or introducing new positioning methods due to the need to change all network components, as existing Location Based Services (LBS) are tied to specific network structures and signaling protocols, lacking a method for terminals to receive or transmit location information independently.
Innovation Solution
A method for transmitting location information using the Secure User Plane Location (SUPL) protocol, allowing a terminal to receive or transmit its location information by sending a start message with MO mode information, calculating the location, and transmitting it according to the specified mode, involving SUPL Enabled Terminals, SUPL Location Platforms, and various servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LBS service is implemented via control plane with network-specific signaling protocols, then positioning service can be provided within network structure, but all network components must be updated when introducing new positioning methods
Solution Approach 1:
The patent introduces a Location Server as an intermediary component that mediates between the terminal and the positioning system. The Location Server handles positioning requests and communicates with terminals using standardized protocols, isolating the core network from protocol-specific implementations. This allows new positioning methods to be introduced by updating only the Location Server rather than all network components.
Solution Approach 2:
The patent segments the positioning system into independent functional modules: terminal equipment, Location Server, and positioning system. Each module operates with defined interfaces and protocols, allowing independent updates and maintenance. The Location Server specifically handles protocol translation and positioning calculation, separating concerns from the core network infrastructure.
2Adaptability or versatility
If User Plane Protocol is used for location information service, then independence from network structure is achieved, but method for terminal to receive or transmit location information is not described
Solution Approach 1:
The patent enables terminals to autonomously initiate positioning requests and receive location information through the Location Server using User Plane Protocol. The terminal can independently send positioning requests, receive calculated location information, and forward it to third parties without requiring control plane intervention. This self-service capability achieves both network independence and operational simplicity.
Solution Approach 2:
The Location Server provides universal functionality by serving multiple purposes: calculating terminal location, receiving requests from terminals, forwarding information to third parties, and supporting various positioning methods. This multi-functional design allows the same infrastructure to support diverse positioning needs while maintaining User Plane Protocol independence.
3Reliability
If control plane signaling is used for LBS service, then positioning service can be integrated into network, but signaling and protocol changes require updating all network components
Solution Approach 1:
The Location Server acts as an intermediary that handles all protocol-specific signaling and positioning calculations. By concentrating protocol handling in this single component, the patent allows positioning service integration into the network while isolating update requirements to only the Location Server, not the entire network infrastructure.
