Mobile Device Caller ID via Remote Directory Lookup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices lack enhanced features for identifying incoming callers and facilitating outgoing calls, requiring users to manually input numbers or rely on incomplete caller ID information, and do not efficiently integrate directory services for email address lookups.
Innovation Solution
Implementing a mobile device with integrated reverse telephone number lookup for incoming calls and forward lookup for outgoing calls, utilizing a directory service for email address lookups, and enabling remote data access to supplement contact information from personal and global address books.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If reverse telephone number lookup is implemented for incoming calls, then caller identification capability is improved, but device complexity and data access requirements increase
Solution Approach 1:
The patent employs directory services as intermediary systems that handle the complex reverse lookup operations remotely. The mobile device acts as a client that queries these external directory services rather than maintaining its own comprehensive reverse lookup database, thereby achieving accurate caller identification without proportionally increasing device complexity.
Solution Approach 2:
The solution moves the reverse lookup functionality from a local device-based system to a network-based distributed system. By transitioning from one-dimensional local storage to multi-dimensional networked directory services, the patent achieves improved caller identification while distributing the complexity burden across the network infrastructure rather than concentrating it in the mobile device.
2Ease of operation
If forward telephone number lookup and email address lookup are integrated into the mobile device, then ease of operation is improved, but use of energy and data access requirements increase
Solution Approach 1:
The patent implements a unified contact information lookup system that handles multiple types of queries (telephone numbers, email addresses, various contact formats) through a single integrated interface. This multi-functional approach improves ease of operation by providing consistent user experience across different lookup types while optimizing energy usage through shared processing logic and cached results.
3Speed
If comprehensive contact information is stored locally in the device, then access speed is improved, but device memory requirements and data synchronization complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-fetching and caching contact information that is likely to be needed based on usage patterns. Frequently accessed contact data is stored locally in the device memory to ensure fast access speed, while less frequently used information remains in remote directory services. This selective pre-positioning of data optimizes the balance between access speed and memory utilization.

AI summary
A mobile device with enhanced telephone call information and a method of using same are provided. In accordance with one embodiment, there is provided a method of providing enhanced phone call information on a mobile communication device, comprising: receiving an incoming call on the device; identifying a contact name in an address book stored in a memory of the device in accordance with a phone number associated with the incoming call when the contact name is not provided with the incoming call; identifying a contact name in a remote contact source in accordance with a phone number associated with the incoming call when the contact name is not provided with the incoming call and not found in the address book stored in a memory of the device; and displaying the identified contact name in a user interface screen on a display screen of the device.
