Trusted Domain Location Service for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solutions for providing location assistance services to mobile devices on private networks require proprietary messaging schemes and application-specific authentication credentials, leading to increased network latency and performance reduction.
Innovation Solution
A wireless carrier configures a location assistance server to treat private networks as trusted domains, allowing mobile devices to access location assistance services without separate authentication, by translating private network addresses into public addresses and using dedicated data pathways, thereby bypassing proprietary messaging schemes and authentication processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary messaging schemes and application-specific authentication credentials are implemented for private network devices, then authentication security is improved, but network latency increases and performance deteriorates
Solution Approach 1:
The patent applies universality by enabling the A-GPS server to handle both public network devices (requiring full authentication) and private network devices (using trusted domain authentication) through a single unified system. The server recognizes trusted private network addresses and provides location assistance without requiring proprietary messaging schemes or application-specific credentials, thus eliminating additional authentication overhead while maintaining security for public networks.
Solution Approach 2:
The patent extracts the authentication step for private network devices from the standard A-GPS authentication flow. By identifying devices from trusted private networks through their network addresses and excluding them from the proprietary authentication process, the system removes the time-consuming authentication operations while preserving them for devices that require security verification.
2Reliability
If proprietary messaging schemes are implemented at each device, then authentication capability is improved, but device complexity and network processing complexity increase
Solution Approach 1:
The patent introduces the A-GPS server as an intermediary that handles authentication for private network devices. Instead of implementing complex proprietary messaging schemes at each device, the server acts as a mediator that recognizes trusted private network addresses and provides location assistance directly. This transfers the authentication complexity from individual devices to the server, simplifying device architecture while maintaining authentication capability.
3Reliability
If separate authentication processes are implemented for different private networks, then network security is improved, but processing time and network latency increase
Solution Approach 1:
The patent applies universality by creating a unified authentication approach for all private network devices. The A-GPS server recognizes multiple private network addresses as trusted domains and provides location assistance through a single standardized process, eliminating the need for separate authentication processes for different private networks while maintaining security boundaries between networks.
Data Source
AI summary
In response to a location assistance request initiated by a mobile device on a private network and directed to a data access port of a location server in a public mobile communication network, a source network address is extracted from the received request. If the extracted source network address is determined to be associated with a trusted private network domain, location assistance data obtained by the location server is provided to the mobile device on the private network without requiring any proprietary messaging schemes or application-specific authentication credentials.
