Caller ID Lookup via External Database Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless devices often fail to provide caller identification for unknown callers, leading to missed important calls or unwanted solicitations, as the phone number may not be associated with any contacts stored on the device.
Innovation Solution
A method and system that allow a wireless device to perform an external database search for caller identification information when the number is not stored locally, using a processor to connect to external databases and communicate the identified information to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If caller identification information is stored only in local wireless device memory, then device complexity is reduced, but caller identification completeness deteriorates
Solution Approach 1:
The patent transitions from a single-dimension local storage approach to a multi-dimensional information retrieval system that combines local wireless device memory with external database resources. This dimensional expansion allows the system to access caller identification information from multiple sources (local contacts and external databases) without increasing local device complexity, thereby resolving the contradiction between maintaining simple device architecture and achieving complete caller identification.
2Measurement precision
If external database search is performed for all unknown callers, then caller identification accuracy is improved, but loss of time increases
Solution Approach 1:
The patent implements a selective external database search strategy where the system first checks local wireless device memory for caller identification information, and only performs external database searches when local information is insufficient or unavailable. This partial action approach avoids unnecessary external searches for all callers, thereby reducing time loss while maintaining high caller identification accuracy for unknown or unrecognized numbers.
3Loss of information
If caller identification information is obtained from external databases, then information completeness is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary communication interface that handles external database searches and information retrieval without requiring complex integration with the core wireless device memory system. This intermediary layer manages the interaction between local storage and external databases, allowing the system to access complete caller identification information from external sources while maintaining relatively simple device architecture by isolating the complexity in a dedicated communication module.

AI summary
The invention is a method, system, and computer-readable medium for gathering and communicating caller identification information on a wireless device. The invention includes receiving, at a wireless device, a calling party phone number to be communicated by the wireless device, determining that the calling party phone number and a corresponding caller identification are not stored on the wireless device memory, performing, in response to the determination that the calling party phone number and the corresponding caller identification are not stored on the wireless device memory, an external database search for the calling party phone number and corresponding caller identification, and determining that the calling party phone number and corresponding caller identification have been identified in the external database search. The invention further includes communicating, in response to the determination that the calling party phone number and corresponding caller identification have been identified in the external database search, the calling party phone number and caller identification.
