Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If current methods for manipulating dial plans are used, then call routing can be achieved, but computing resource consumption is excessive and processing speed is slow
Solution Approach 1:
The patent applies preliminary action by pre-processing the dial plan configuration file into a compiled state machine representation before actual call routing operations. The dial plan is transformed into a finite state machine with predefined states, transitions, and patterns during system initialization or configuration loading, so that during runtime, the gateway can efficiently match incoming call patterns against the pre-compiled state machine without performing complex parsing operations, thereby reducing computing resource consumption and improving processing speed
Solution Approach 2:
The patent replaces the mechanical system of traditional dial plan manipulation methods with a state machine-based computational model. Instead of using conventional pattern-matching algorithms or rule-based systems that require extensive computing resources, the invention substitutes a finite state machine that uses predefined states and transitions to efficiently process dial patterns, achieving faster processing with reduced computational overhead
2Ease of operation
If traditional dial plan manipulation methods are used, then call routing is possible, but the process is cumbersome and expensive to implement
Solution Approach 1:
The patent applies self-service by enabling the system to automatically compile and process dial plan configurations without requiring manual intervention or complex setup procedures. The gateway automatically parses the dial plan configuration file, compiles it into a state machine representation, and maintains it for efficient querying, eliminating the need for manual configuration management and reducing operational complexity
Solution Approach 2:
The patent changes the fundamental parameters of how dial plans are represented and processed. Instead of using traditional rule-based or table-driven approaches, the invention transforms the dial plan into a state machine model with defined states, transitions, and patterns. This parameter change simplifies the manipulation process by providing a unified framework for handling dial plan operations
3Measurement precision
If extensive computing resources are allocated for dial plan processing, then pattern-matching accuracy can be maintained, but processing time increases and revenue is lost
Solution Approach 1:
The patent applies preliminary action by pre-compiling the dial plan configuration into a state machine structure with predefined patterns, states, and transitions before runtime operations. This pre-processing ensures that pattern-matching accuracy is maintained while enabling fast lookup and decision-making during actual call routing, thereby reducing processing time and minimizing revenue loss without sacrificing matching precision
Solution Approach 2:
The patent applies dynamics by implementing a state machine that can dynamically transition between states based on incoming dial patterns. The state machine structure allows for efficient runtime adaptation and decision-making, maintaining high pattern-matching accuracy while enabling rapid processing through predefined transition paths and optimized state evaluations
