Service Provider Code Verification for Real-Time Call Authorization

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing call validation methods are burdensome and do not provide real-time scam call management, as they fail to efficiently verify the legitimacy of incoming calls using conventional service provider identifiers.

Innovation Solution

Implementing a method that utilizes a service provider code (SPC) to authenticate calls by determining a service provider network identifier from a call origination device, retrieving a service provider code from a public certificate, and verifying its match with a verification table, ensuring real-time authorization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional call validation methods are used, then call legitimacy verification is performed, but the process is burdensome and not fast enough for real-time scam call management

Engineering Contradiction:

Improvecall validation speedVSAvoidvalidation process complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts the critical verification element (service provider code) from the complex call validation process and validates it independently against a verification table. This separates the essential authentication step from other processing steps, enabling faster real-time validation while reducing overall process complexity.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The service provider code is pre-configured in the verification table before calls are validated. This preliminary preparation allows the system to perform rapid lookups and comparisons during actual call validation, eliminating the need for complex real-time analysis and enabling real-time scam call management.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If service provider code verification is implemented, then spoof call reduction is improved, but additional verification steps are required

Engineering Contradiction:

Improvecall authorization accuracyVSAvoidverification steps

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses a simplified copy of the service provider's identification (the service provider code) rather than verifying the entire service provider infrastructure. This single code copy enables reliable spoof call detection while minimizing the number of verification steps required.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The service provider code acts as an intermediary element between the call origination device and the verification system. This single verification point mediates the authentication process, improving reliability while keeping the verification steps manageable through centralized code validation.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

One example method of operation may include receiving a call message associated with a call, determining a service provider network identifier based on a telephone number of a call origination device, identifying, from the call message, an identity header with a link to a public certificate repository storing a public certificate assigned to a service provider network hosting the call origination device, retrieving a service provider code assigned to the service provider network from the public certificate, and determining whether the service provider code matches the service provider network identifier as identified from a verification table.
