Subscriber Routing System for Unified Policy Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telecommunications networks face challenges in providing a unified view of subscriber activities across different legacy and IP-based services due to the use of multiple subscriber identifiers and protocols, making it difficult to manage traffic and offer personalized services.
Innovation Solution
A subscriber-centric routing system that associates multiple subscriber identifiers with a Global Unique Identifier (GUID) and routes all sessions to a single processing element, allowing for a unified subscriber profile and improved policy management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple subscriber identifiers and protocols are used across different legacy and IP-based services, then service compatibility and legacy support are improved, but system complexity and difficulty in obtaining unified subscriber view increase
Solution Approach 1:
The patent introduces a home agent as an intermediary component that receives binding updates from network layer mobility protocols and translates them into location management information. This mediator bridges the gap between different protocol systems (legacy circuit-switched and modern IP-based networks), enabling unified subscriber tracking without requiring direct integration between disparate systems. The home agent acts as a translation layer that harmonizes multiple identifier types (e164, IMSI, SIP URI) and protocols into a common framework.
2Adaptability or versatility
If separate applications are used for different protocols and services, then protocol-specific functionality is improved, but ability to obtain complete subscriber activity view deteriorates
Solution Approach 1:
The patent merges the functionality of multiple protocol-specific applications into a unified location management system. Instead of having separate siloed applications for circuit-switched and IP-based services, the invention combines them under a single home agent that maintains a unified location database. This consolidation allows the system to track subscriber activities across all services and protocols simultaneously, eliminating information loss while preserving protocol-specific capabilities through standardized interfaces.
3Reliability
If data synchronization is implemented between multiple data stores, then data consistency is improved, but processing overhead and complexity increase
Solution Approach 1:
The patent extracts the location management functionality from distributed data stores and consolidates it into a centralized location database within the home agent. By taking out the location tracking responsibility from multiple service-specific databases and centralizing it, the system eliminates the need for complex synchronization protocols between data stores. The centralized database becomes the single source of truth for subscriber location information, reducing processing overhead while maintaining data consistency across all services.

AI summary
In accordance with various embodiments, systems and methods of mapping an event related to a subscriber to an associated subscriber profile associated with a global unique identifier (GUID) associated with the specific subscriber, regardless of the particular subscriber identifier associated with the event. The system includes a routing module which is operable to resolve the GUID from a variety of identifiers and identifier types which might be associated with an event. The method can receive a subscriber identifier associated with an event, resolve the subscriber identifier to a global unique identifier (GUID), and route the event to a single actor for processing in accordance with the subscriber's profile and thereby provide the appropriate services and quality of service.
