Location Services Using Publish-Subscribe Formats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telecommunication networks face challenges in monetizing location-based services due to high latencies in precision location determination, resource consumption, and a lack of integration with next-generation network technologies, as well as a desire to control device platforms, limiting third-party access to processing power and capabilities.
Innovation Solution
A system and method that utilizes publish-subscribe formats for location information based on user preferences, integrating with Web 2.0 technologies like RSS and ATOM feeds, and supports Session Initiation Protocol (SIP) and Diameter integration for IP Multimedia Subsystem (IMS) networks, allowing mobile users to publish their location information efficiently and configure updates, enabling peer-to-peer communication and value-added tracking applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional location determination methods (triangulation via cell towers or GPS) are used, then location precision is improved, but network resource consumption and latency increase
Solution Approach 1:
The patent extracts the location determination function from the network infrastructure and relocates it to the mobile device itself. The device's web browser and processing capabilities are used to determine location by analyzing webpage content and coordinates, eliminating the need for continuous network-based triangulation or GPS queries, thus reducing network resource consumption while maintaining location precision.
Solution Approach 2:
The mobile device performs location determination autonomously using its own processing power, web browser, and access to location information embedded in webpages. The device self-determines its location without requiring network carrier intervention or infrastructure, enabling third-party location services to leverage device capabilities directly.
2Reliability
If network carriers control all services on device platforms, then service control and security are improved, but third-party access to device processing power and capabilities is limited
Solution Approach 1:
The patent introduces webpages as an intermediary layer between the network carrier and device capabilities. Location information and coordinates are embedded within standard web content, allowing third-party services to access device processing power through the web browser without requiring direct carrier intervention or special permissions, thus maintaining carrier control while enabling third-party innovation.
3Measurement precision
If precision location determination is performed frequently, then location accuracy is improved, but latency increases
Solution Approach 1:
The patent performs preliminary location determination by embedding coordinates and location information in webpages before the user actually needs the location data. When a webpage is loaded, the location information is already available in the content, eliminating the need for real-time location queries and reducing latency while maintaining accuracy.
Data Source
AI summary
A system and method is provided for providing location based services. The system includes at least one module configured to publish location information of a mobile user using a publish subscribe format based on a user preference mode of notification.
