Flow Control Center for Dynamic SMS Traffic Shunting

Solution Overview

Problem

Current SMS systems lack the ability to dynamically adjust traffic distribution based on the load conditions of individual SMS systems, leading to potential overburdening of backup systems during disaster recovery, which can impact reliability and stability.

Innovation Solution

The introduction of a Flow Control Center (FCC) that connects with multiple SMS systems, allowing for the determination of optimal flow paths for short messages based on the operating conditions and load capacities of SMSCs and GIWs, enabling intelligent routing and redundant path management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If uniform traffic allocation is used during disaster recovery, then the backup system can receive all redirected messages, but the backup system may become overburdened and impact reliability

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements dynamic traffic allocation by introducing a Flow Control Center (FCC) that monitors the load status of backup SMSCs in real-time and adjusts message routing accordingly. The FCC receives status information from SMSCs, determines optimal flow paths based on current load conditions, and dynamically redirects messages to balance traffic distribution, preventing any single backup system from becoming overburdened while maintaining SMS service continuity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent establishes a feedback mechanism where SMSCs periodically report their load status to the Flow Control Center. The FCC uses this feedback information to make informed routing decisions, selecting backup SMSCs with available capacity to receive redirected messages. This closed-loop feedback system ensures that traffic allocation is continuously optimized based on actual system conditions, preventing overload of backup systems.

Inventive Principle:
Principle #23Feedback

2Reliability

If backup relation is established between SMS systems, then disaster recovery capability is improved, but the system complexity increases

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a Flow Control Center (FCC) as an intermediary component that manages the complexity of backup system coordination. The FCC acts as a central controller that receives status information from multiple SMSCs, determines optimal routing decisions, and coordinates traffic distribution among backup systems. This intermediary approach simplifies the overall system architecture by centralizing the complex routing logic, allowing individual SMSCs to focus on their core message processing functions without managing backup coordination themselves.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If traffic is redirected to backup GIW/SMSC, then signaling level disaster recovery is achieved, but the routing processing becomes excessively simple and cannot consider load conditions

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent transforms the static backup routing mechanism into a dynamic system by introducing the Flow Control Center that continuously monitors load conditions and adjusts routing decisions in real-time. The FCC receives status information from SMSCs and GIWs, evaluates current system state, and dynamically determines optimal flow paths for redirected messages. This dynamic approach allows the system to adapt traffic allocation to changing load conditions, preventing rigid routing from overwhelming specific backup nodes while maintaining reliable disaster recovery capabilities.

Inventive Principle:
Principle #15Dynamics
