Service Provider Code Verification for Real-Time Call Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current call validation methods are burdensome and not fast enough to support real-time scam call management, as they often rely on manual operations and lack efficient mechanisms to differentiate between legitimate and illegitimate calls.
Innovation Solution
The proposed solution involves using a service provider code (SPC) linked to a public certificate repository, where a service provider network identifier is determined from a call message, and verified against a verification table to authenticate calls, enhancing call authorization and verification processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional call validation methods are used, then call verification can be performed, but the process is burdensome and not fast enough for real-time scam call management
Solution Approach 1:
The patent performs preliminary actions by pre-establishing a verification table that maps service provider network identifiers to service provider codes before calls need validation. This pre-computed mapping enables rapid lookup during actual call verification, eliminating the need for time-consuming real-time validation operations and achieving real-time scam call management.
Solution Approach 2:
The patent creates a simplified copy of the verification process by using pre-computed mappings between service provider network identifiers and service provider codes. Instead of performing complex real-time validation, the system uses these pre-prepared mappings to quickly determine call legitimacy, significantly reducing verification time while maintaining accuracy.
2Ease of operation
If manual operations are used for call validation, then verification can be performed, but the process is burdensome and inefficient
Solution Approach 1:
The patent implements self-service by enabling the system to automatically perform call validation using pre-established verification tables that map service provider network identifiers to service provider codes. The system autonomously compares extracted network identifiers against the verification table without requiring manual intervention, thereby simplifying the validation process and improving management efficiency.
3Reliability
If current validation approaches are used, then call verification is possible, but they do not provide real-time scam call management capability
Solution Approach 1:
The patent performs preliminary action by pre-computing and storing the verification table with service provider network identifier to service provider code mappings before scam detection is needed. This pre-prepared data structure enables instant lookup during call verification, achieving real-time scam detection while maintaining high verification accuracy through the pre-established mapping relationships.

AI summary
One example method of operation may include extracting a calling device telephone number from a received call message, querying a verification table for the calling device telephone number, identifying the calling device telephone number and a corresponding service provider network identifier from the verification table, querying a mapping table for the service provider network identifier, and identifying whether a match between the service provider network identifier and a service provider code exists as an entry in the mapping table.
