Telephone Call Identity Attributes Across Carrier Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of malicious robocalls is exacerbated by the lack of uniformity across the telecommunications industry and the inability of enterprises to effectively inject metadata into calls, leading to challenges in identifying call origins and enabling deceptive practices.
Innovation Solution
A system that determines the terminating telecommunication service provider and available identification options, selects appropriate metadata to include in the call, and optimizes the call route to ensure proper transmission of identity attributes, integrating with existing infrastructure to enhance caller verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If telecommunication service providers deliver telephone calls with extra metadata including enterprise name, reason for call, and logo, then caller verification is improved, but implementation success is reduced due to lack of industry uniformity and carrier maze
Solution Approach 1:
The patent introduces an intermediary system that mediates between the caller and the telecommunication service providers. This intermediary handles the complexity of navigating through multiple carriers and injecting metadata, allowing individual providers to implement verification without needing industry-wide uniformity. The intermediary translates caller requests into provider-specific metadata formats, resolving the contradiction between improving verification and adapting to diverse provider implementations.
Solution Approach 2:
The patent segments the caller verification function into separate components: the intermediary that prepares metadata, the telecommunication service providers that transmit calls with metadata, and the recipients that verify caller identity. This segmentation allows each component to operate independently with different levels of capability, resolving the uniformity issue while maintaining overall system reliability for caller verification.
2Loss of information
If enterprises inject extra metadata into telephone calls, then caller identification is improved, but technical capability requirements increase
Solution Approach 1:
The patent enables enterprises to self-serve by providing them with tools and interfaces to inject their own metadata into outgoing calls. Instead of requiring complex technical capabilities, the system offers simplified mechanisms for enterprises to add verification information automatically, reducing the technical barrier while maintaining information completeness.
Solution Approach 2:
The intermediary acts as a mediator between enterprises and the complex telecommunication infrastructure. It handles the technical complexity of metadata injection, carrier navigation, and format translation, allowing enterprises to focus on providing verification information without needing deep technical expertise in telecommunication protocols.
3Reliability
If telecommunication service providers trust and process identity attributes from multiple carriers, then caller verification is enhanced, but system complexity increases due to lack of uniformity
Solution Approach 1:
The patent introduces a standardized metadata format that all telecommunication service providers can adopt uniformly. This homogeneous structure allows providers to process identity attributes from multiple carriers without increasing system complexity, as the standardized format ensures consistent interpretation and handling of verification data across different providers and carriers.
Data Source
AI summary
Telephone calls can be intelligently delivered with identity attributes as described herein. In one example, a system can receives communication associated with a caller requesting to make a telephone call to a recipient, where the communication includes a recipient identifier associated with the recipient. The system can determine a terminating telecommunication service provider (TTSP) to which the telephone number is assigned. The system can then determine identification options available at the TTSP, where each identification option can be configured to provide one or more identity attributes associated with the caller to the recipient. The system can select one or more of the identification options based on a predefined policy and modify the communication to include the one or more identity attributes associated with the one or more selected identification options, thereby producing a modified communication. The system can then transmit the modified communication along a call route to the TTSP.
