Mobile Device Removal from Local Service Domains by Gateway Polling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of managing user identities, preferences, and data across multiple communication devices and services in residential and business environments, particularly when shared by multiple users, is not adequately addressed by existing technologies.
Innovation Solution
A profile-based system is employed to manage user identities and preferences, using servers in an external network and a customer premises equipment (CPE) gateway to map users to devices and services, providing unified notification summaries, audio and visual indicators, and controlling notification delivery across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices are used to access communication services, then service coverage and user convenience are improved, but management complexity of user identities and preferences increases
Solution Approach 1:
The patent extracts user identity and preference management from individual devices and centralizes it in a network server. Each device only needs to store minimal local data, while the server maintains the master profile database, thereby reducing device complexity while preserving multi-device service coverage.
Solution Approach 2:
The network server implements a universal profile management system that serves multiple devices and multiple users through a single centralized infrastructure. This universal system handles identity mapping, preference storage, and notification routing for all devices in the domain, eliminating the need for separate management systems on each device.
2Stability of the object's composition
If user profiles are maintained centrally in external networks, then data consistency and synchronization are improved, but network dependency and access complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-establishing device profiles and identity mappings in the network server before actual communication occurs. When a device joins the domain, the server proactively provisions the necessary profile data and routing information, eliminating the need for complex real-time negotiations during communication sessions.
Solution Approach 2:
The CPE gateway acts as an intermediary between external network elements and local devices. It simplifies access to centralized profiles by providing a local caching mechanism and translation layer, allowing devices to access profile data through simple local queries while the gateway handles complex network communication and profile synchronization.
3Loss of time
If notifications are delivered to multiple devices simultaneously, then user awareness and response time are improved, but notification management and synchronization complexity increase
Solution Approach 1:
The patent introduces a new dimension of profile-based routing by adding user identity and device preference attributes to the notification delivery process. Instead of simple broadcast to all devices, the system uses profile data to intelligently route notifications to specific devices based on user context, device capabilities, and communication type, thereby reducing management complexity while maintaining simultaneous delivery capability.
4Adaptability or versatility
If a mobile device joins and leaves the local service domain dynamically, then system flexibility and user mobility are improved, but identity mapping and service continuity complexity increase
Solution Approach 1:
The system implements dynamic profile activation and deactivation mechanisms. When a mobile device joins the domain, its profile is automatically activated in the network server with appropriate service permissions. When the device leaves, the profile is deactivated but preserved for future reactivation, enabling seamless mobility without complex re-provisioning procedures.
Data Source
AI summary
A mobile device configurable for direct communication in a wide area wireless network may join a local service domain and receive services through a gateway of that local service domain. The mobile device may be removed from the local service domain if the mobile device has been inactive for a threshold time period, the gateway device receives data indicating that the mobile device has been added to a different service domain, or a reply for a polling message sent to the mobile device has not been received.
