Clearing House Caller Validation Across Signaling Protocols
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network operators lack reliable methods for verifying the trustworthiness of communications originating from other networks operating on different signaling protocols, leading to increased susceptibility to fraudulent activities and network congestion.
Innovation Solution
An interworking device that applies policy rules, verifies caller information through certification procedures, and converts communication requests between different signaling protocols, using indicators like certificates and signatures to ensure secure communication across networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network operators verify caller information from other networks using different signaling protocols, then network security improves, but device complexity increases
Solution Approach 1:
The patent introduces a clearing house as an intermediary entity that mediates verification between networks using different signaling protocols. The clearing house receives verification requests, performs certification procedures, and returns verification results, thereby enabling secure verification without requiring direct complex integration between disparate network systems.
2Object-affected harmful factors
If network operators implement certification procedures for all communication requests, then fraudulent communications decrease, but processing demand and network congestion increase
Solution Approach 1:
The patent implements preliminary certification procedures where the clearing house pre-verifyes caller information before the actual communication takes place. By performing verification in advance and caching results, the system prevents fraudulent communications without requiring real-time verification of every single communication request, thus maintaining network throughput.
3Adaptability or versatility
If networks convert communication requests between different signaling protocols, then adaptability improves, but processing time increases
Solution Approach 1:
The patent performs protocol conversion and certification procedures in advance before the actual communication request needs to be processed. By pre-converting protocols and pre-performing verification, the system reduces the processing time required during actual communication operations, thereby minimizing time loss while maintaining high adaptability.
Data Source
AI summary
In one embodiment, a network interface receives a communication request. A processor then verifies caller information in the communication request with a certification procedure. The processor obtains a first indicator based on the certification procedure. The first indicator includes information associated with a first certificate management procedure. The processor generates a second indicator based on the first indicator. The second indicator includes information associated with a second certificate management procedure.
