Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telephony service providers face challenges in establishing secure and scalable interfaces with third-party business service providers to manage provisioning of accounts, devices, and services, as existing systems lack reliable infrastructure for authentication and API call routing.
Innovation Solution
A method and apparatus for routing API calls from partner entities to a telephony service provider network, involving authentication using partner API keys, with a secure proxy layer that manages key generation, authentication, and API call routing, ensuring secure and scalable access to the partner API layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure authentication system is implemented using API keys, then network security is improved, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary authentication system that mediates between partner entities and the TSP network. This intermediary layer handles API key generation, distribution, and validation, isolating the complexity of security management from both the network core and external partners. The intermediary acts as a secure proxy that simplifies the overall system architecture while maintaining high security standards.
2Adaptability or versatility
If a scalable infrastructure is built to support multiple partner entities, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal authentication and routing infrastructure that serves multiple partner entities through a common framework. The system uses standardized API key mechanisms and unified routing logic that can accommodate any number of partners without requiring separate infrastructure for each. This multi-functional design enables scalable onboarding of new partners while maintaining consistent security and routing protocols.
Solution Approach 2:
The system segments the infrastructure into modular components: authentication module, API key management module, and routing module. Each component operates independently and can be scaled or modified without affecting others. This segmentation allows the system to handle multiple partner entities efficiently by processing each partner's requests through the same modular pipeline, reducing overall infrastructure complexity.
3Reliability
If authentication processes are performed for every API call, then reliability is improved, but processing time increases
Solution Approach 1:
The patent implements preliminary authentication where API keys are generated and distributed to partner entities before they begin making API calls. The authentication process occurs in advance during partner onboarding, and the validated API keys are cached for subsequent use. This allows the system to verify partner identity efficiently during runtime without repeating the full authentication process for each API call, significantly reducing processing time while maintaining authentication reliability.

AI summary
A method and apparatus for routing Application Programming Interface (API) calls from a partner entity to a telephony service provider (TSP) network are provided herein. In some embodiments, a method for routing API calls may include receiving a first message including an API call and a partner API key used to authenticate the partner entity on the TSP network to access a partner API layer disposed on the TSP network, extracting the partner API key from the first message, performing an authentication process to authenticate an identity of the partner entity using at least the extracted partner API key, and routing the first message based on results of the authentication process. In some embodiments, the first message is routed to the partner API layer disposed on the TSP network when the identity of the partner entity is authenticated.
