Proxy Server for Roaming Location Request Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, determining the appropriate Position Determining Entity (PDE) for forwarding location requests from a mobile station in a roaming environment is challenging, as existing systems often rely on direct connections to the mobile station's home radio network, which can complicate the identification and routing of PDE requests.
Innovation Solution
A proxy server is introduced to receive, forward, and modify data from a mobile station to a PDE, utilizing subscriber and network information databases to determine whether to forward requests and identify the appropriate route, thereby acting as a clearinghouse for location requests and managing authorization, routing, and billing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a direct connection is used between mobile station and home radio network for location requests, then routing simplicity is maintained, but the ability to determine appropriate PDE in roaming environment deteriorates
Solution Approach 1:
A proxy server is introduced as an intermediary component between the mobile station and the PDE. The proxy server receives location requests from mobile stations, determines the appropriate PDE based on subscriber and network information, and forwards the requests accordingly. This mediator resolves the contradiction by providing intelligent routing decisions without requiring complex direct connections between mobile stations and multiple PDEs.
2Reliability
If proxy server is introduced to manage location requests, then routing accuracy and security are improved, but system complexity increases
Solution Approach 1:
The proxy server is designed to perform multiple functions: receiving location requests, determining appropriate PDEs, forwarding requests, modifying data, and blocking unauthorized access. By consolidating these diverse functions into a single multi-functional component, the system achieves improved routing accuracy and security without proportionally increasing overall system complexity.
3Reliability
If proxy server processes location requests through databases, then authorization and billing control are improved, but processing time increases
Solution Approach 1:
Subscriber and network information are pre-stored in databases at the proxy server before actual location requests arrive. When a request comes in, the proxy server can quickly query pre-organized data rather than performing real-time complex determinations. This preliminary preparation of reference data enables fast authorization and routing decisions while maintaining strong control capabilities.
