Telephony Call Routing With Modified Caller ID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telephony systems fail to accurately convey calling party identifier information when calls are transferred, leading to confusion for the second called party, as the information may be inaccurate or limited, such as displaying 'Anonymous' or incomplete names.
Innovation Solution
A method and system that modify calling party identifier information based on modification information received from the first called party, allowing the telephony communication to be routed to a second called party with accurate and relevant identifier information, such as names or codes, to enhance recognition and acceptance of the call.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the original calling party's calling line identification information is displayed when a call is transferred, then the second called party can see the original caller's information, but the information may be inaccurate or limited (e.g., showing 'Anonymous' or incomplete names) which causes confusion
Solution Approach 1:
The patent introduces an intermediary entity (the call processing system) that generates a modified calling party identifier combining information from both the original calling party and the first called party. This intermediary solution resolves the contradiction by providing accurate information without causing confusion, as the modified identifier clearly indicates the call was transferred while preserving the original caller's identity.
Solution Approach 2:
The patent changes the parameter of the calling party identifier by generating a modified version that incorporates multiple sources of information (original caller ID and first called party ID). This parameter transformation resolves the contradiction by converting inaccurate or limited information into comprehensive and clear identification information.
2Measurement precision
If calling line identification information is displayed during call transfer, then the second called party can identify the original caller, but the information may not be useful (e.g., unclear whether it's Dianne or Dave Rogers, or even Grandpa)
Solution Approach 1:
The patent merges multiple sources of identification information (original calling party identifier and first called party identifier) into a single modified calling party identifier. This combination resolves the contradiction by preserving precise identification while eliminating ambiguity, as the merged identifier provides complete context about the call origin.
Solution Approach 2:
The patent transforms the calling party identifier parameter by integrating multiple information sources, converting imprecise or ambiguous identification into precise and clear caller identity information that the second called party can understand.
3Reliability
If the calling party identifier is modified based on information from the first called party, then accurate and relevant identifier information is provided to the second called party, but this requires additional processing and information exchange
Solution Approach 1:
The patent implements a universal call processing mechanism that handles both original and transferred calls through the same modified identifier generation process. This multi-functional approach resolves the contradiction by providing reliable identification without significantly increasing system complexity, as the same processing logic applies to various call scenarios.
Solution Approach 2:
The patent uses an intermediary call processing system that automatically generates modified calling party identifiers by combining information from multiple sources. This intermediary solution resolves the contradiction by ensuring reliable identification while managing system complexity through automated processing rather than manual intervention.

AI summary
A method, comprising causing a telephony communication originating from a calling party communication device to be routed to a first called party communication device together with calling party identifier information associated with the calling party communication device. The method further comprises receiving an identification of a second called party communication device to which the telephony communication should be routed, and generating modified calling party identifier information associated with the telephony communication on the basis of modification information received from the first called party communication device. Finally, the method comprises routing the telephony communication to the second called party communication device together with the modified calling party identifier information.
