Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of wireless and cellular networks has increased due to expanding user demand and new services, making efficient routing and management of signaling traffic a challenging task, as existing solutions lack flexibility and intelligence in handling protocol variations and network topology.
Innovation Solution
A dynamic context router is introduced, which operates as a protocol-agnostic, application-level router and load balancer, capable of performing message routing, relay, and redirect operations, making intelligent decisions based on message content and dynamically updating routing algorithms, while also handling protocol translation and failover operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional routing methods are used in expanding telecommunications networks, then network coverage and user capacity increase, but routing efficiency and management complexity deteriorate
Solution Approach 1:
The patent introduces a Diameter Routing Agent (DRA) as an intermediary component that mediates routing decisions between network elements. The DRA receives routing requests, determines optimal routing paths based on network state, and returns routing information to requesting elements, thereby simplifying routing management in expanding networks without requiring complex distributed routing logic across all network elements
Solution Approach 2:
The patent implements feedback mechanisms where network elements provide routing state information to the DRA, which uses this feedback to dynamically adjust routing decisions. The DRA monitors network conditions and adapts routing paths based on received feedback, enabling efficient routing management as the network expands and conditions change
2Measurement precision
If protocol-specific routing implementations are used, then protocol handling accuracy improves, but system adaptability and complexity worsen
Solution Approach 1:
The patent implements a universal routing architecture where the DRA handles multiple Diameter protocol applications and command types through a single unified component. The DRA provides protocol-agnostic routing functionality that can accommodate various protocol variations without requiring separate routing implementations for each protocol type, thereby maintaining accuracy while improving adaptability
Solution Approach 2:
The patent uses parameter-based routing where routing decisions are made based on configurable parameters and attributes within Diameter messages rather than protocol-specific logic. This allows the system to handle different protocol variations by changing routing parameters without altering the fundamental routing mechanism, maintaining accuracy while enhancing adaptability
3Stability of the object's composition
If centralized routing control is implemented, then routing consistency improves, but system scalability and response time worsen
Solution Approach 1:
The patent implements preliminary routing setup where the DRA pre-calculates and caches routing paths based on network configuration and state. When routing requests arrive, the DRA can quickly return pre-determined routing information without performing complex real-time calculations, thereby maintaining consistency while improving response time and scalability
4Speed
If network elements directly route messages without intermediation, then routing speed improves, but routing intelligence and adaptability worsen
Solution Approach 1:
The patent introduces the DRA as an intelligent intermediary that performs automated routing decisions based on message content, network state, and configurable policies. The DRA analyzes incoming messages, determines appropriate routing paths using intelligent algorithms, and forwards messages accordingly, thereby adding routing intelligence and adaptability while maintaining acceptable speeds through efficient processing

AI summary
Methods, servers and systems for communicating signaling information in a policy and charging control network within a telecommunications signaling network, may include receiving a message encoding signaling information in a dynamic context router operating at the application layer. The dynamic context router may determine whether the received message is to be replicated, and if so, the dynamic context router may identify a primary destination to which the received message is to be sent and secondary destinations to which replicated messages ("fork-routed messages") are to be sent. The message may be replicated into multiple fork-routed messages, with the original message sent to the primary destination and the fork-routed messages sent to secondary destination components. The replicated fork-routed messages may be the same as or different from the received message, and may be sent using the same protocol or different protocols.
