Unified Contact List Client for Multi-Service Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of managing contact information across multiple communication services and devices leads to difficulties in maintaining up-to-date and synchronized contact lists, as individuals often use various networks and services for different types of communications.
Innovation Solution
A client device receives a contact list client application that requests and merges contact lists from multiple servers, allowing users to access and update contact information through a single application, integrating different communication formats like voice, SMS, and email into a single view, and synchronizes changes across associated servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate contact lists are maintained for different communication services, then each service can have its own updated contact information, but the complexity of managing and synchronizing these lists increases significantly
Solution Approach 1:
The patent combines multiple service-specific contact lists into a single unified contact list that aggregates contacts from email, instant messaging, and other communication services. This unified list is maintained on both the server and client sides, allowing users to manage all contacts through one interface while the system automatically handles synchronization across different services, thereby reducing management complexity while maintaining information accuracy.
Solution Approach 2:
The contact list system is designed to be service-agnostic, supporting multiple communication services (email, instant messaging, voice calls) through a universal contact list structure. The system can retrieve, store, and synchronize contact information from various service providers using a common interface, making the contact management system adaptable to different communication platforms without requiring separate management mechanisms for each service.
2Stability of the object's composition
If contact lists are synchronized across multiple devices, then contact information remains consistent across platforms, but the time and network resources required for synchronization increase
Solution Approach 1:
The system performs preliminary synchronization by pre-fetching and caching contact list data from multiple services during idle periods or when network conditions are favorable. The client device maintains a local copy of the unified contact list that can be accessed immediately without requiring real-time network synchronization, thereby reducing perceived synchronization time while maintaining data consistency through periodic updates.
Solution Approach 2:
The synchronization mechanism employs feedback loops where the client device periodically checks for changes on the server and pushes local changes back to the server. The system monitors synchronization status and automatically initiates updates when discrepancies are detected, ensuring contact list consistency across devices while optimizing network usage by only transferring changed data rather than complete lists.
3Ease of operation
If a unified contact list aggregates contacts from multiple services, then users can access all contacts from one interface, but the difficulty of keeping the list updated across different services increases
Solution Approach 1:
The system implements self-service mechanisms where the client application automatically retrieves contact information from multiple service providers without requiring user intervention. The application handles authentication, data retrieval, merging, and conflict resolution autonomously, updating the unified contact list in the background. Users simply interact with the unified interface while the system manages the complexity of maintaining synchronization across different services automatically.

AI summary
A contact list client application running on a client device operates to request and receive contact lists over a network from a plurality of different contact list servers, and the application stores the contacts from these lists in a merged contact list. When a user selects a contact in the merged list, the contact list client application identifies one out of a plurality of communication applications on the client device and causes the identified communication application to initiate communications with the contact. Contact lists that relate to different communications formats, such as voice communications, SMS (short message service) messages, and email can be integrated into a single client view on the client device.
