Wireless Caller ID Relay via Selective Data Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing caller identification systems in hands-free accessory devices connected via Bluetooth do not provide caller names, relying solely on caller numbers, which can lead to memory and security issues when implementing the Bluetooth Phone Book Access Profile (PBAP) and require pre-recording voice tags in alternative solutions.
Innovation Solution
A method where a mobile device establishes a short-range wireless connection with an accessory device to transmit caller information, including names, using a non-linear search algorithm to match incoming numbers with directory entries, allowing the accessory device to provide audible caller information without duplicating address book data or requiring voice tags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the Bluetooth Phone Book Access Profile (PBAP) is implemented to provide caller names, then caller identification capability is improved, but memory resources and security risks increase due to duplicating address book data on the accessory device
Solution Approach 1:
The patent extracts only the necessary caller identification information (caller names) from the complete address book data and transmits it selectively to the accessory device. This avoids duplicating the entire address book, thereby reducing memory resource consumption on the accessory device while still providing the needed caller identification capability.
Solution Approach 2:
The patent segments the address book data transmission by sending only specific records (caller names) rather than the complete address book. This selective data transmission approach divides the data flow into essential information only, reducing the overall data volume stored on the accessory device while maintaining functional requirements.
2Loss of information
If the Bluetooth Phone Book Access Profile (PBAP) is implemented to provide caller names, then caller identification capability is improved, but security risks increase due to duplicating sensitive address book data on the accessory device
Solution Approach 1:
The patent extracts only the essential caller identification information needed for the hands-free function and transmits it to the accessory device. By extracting and transmitting only this minimal necessary data rather than the complete address book, the security risk of exposing sensitive personal information on the accessory device is significantly reduced.
3Loss of information
If voice tags are pre-recorded for caller identification, then caller name annunciation is improved, but device complexity and user setup time increase
Solution Approach 1:
The patent enables the accessory device to automatically receive and process caller identification information directly from the mobile device through the wireless connection. This self-service mechanism eliminates the need for manual voice tag recording by users, as the system automatically retrieves and announces caller names through the established data transmission protocol.

AI summary
A method enables a mobile device to provide caller information stored on the mobile device to an accessory device that is connected wirelessly to the mobile device. The method includes establishing a short-range wireless connection between the mobile device and the accessory device, determining an incoming telephone number for an incoming telephone call, searching a directory stored on the mobile device for an entry matching the incoming telephone number, and transmitting caller data from the entry matching the incoming telephone number to the accessory device.
