Solution Overview

Problem

Users face difficulties in managing multiple devices that share the same service identifier for communication services, as existing solutions lack an efficient method to activate or deactivate silent operation modes across all devices simultaneously, leading to inconvenience and increased network costs.

Innovation Solution

A method and system that allow users to activate or deactivate a silent operation mode on one device and propagate this setting to other devices within the same user device group through a control server, using push notifications or cloud synchronization, enabling synchronized management of multiple devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manually manage silent operation mode on each device individually, then each device can be controlled precisely, but user effort and time consumption increase significantly

Engineering Contradiction:
Improveease of managing silent modeVSAvoidtime for individual device configuration
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

A control server acts as an intermediary between user devices and the network. When a user activates silent operation mode on one device, the control server receives the notification and automatically propagates the setting to all other devices in the user device group, eliminating the need for manual configuration on each device.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system segments the management function by separating device control into individual device actions (user activates silent mode on one device) and group-wide propagation (control server distributes the setting to all devices). This allows local user action to trigger global effect without requiring global user intervention.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If silent operation mode is activated on multiple devices simultaneously, then user experience improves, but network configuration costs increase

Engineering Contradiction:
Improvesynchronized device managementVSAvoidnetwork configuration cost
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The control server maintains a pre-established mapping between service identifiers and user device groups. When silent operation mode is activated, the server uses this pre-existing knowledge to quickly identify and notify all relevant devices, avoiding the need for expensive real-time network discovery and configuration procedures.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Instead of creating new network configurations for each device, the system copies the silent operation mode setting from one device to others through the control server. This copying mechanism is more efficient than establishing separate configurations, reducing network configuration costs while achieving synchronized management.

Inventive Principle:
Principle #26Copying

3Reliability

If multi-device support is provided without centralized control, then device independence is maintained, but coordination between devices becomes difficult

Engineering Contradiction:
Improvedevice operation consistencyVSAvoidsystem coordination complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control server serves as a centralized coordinator that receives notifications from individual devices and distributes control commands to the entire user device group. This intermediary structure maintains device independence while enabling reliable coordination, as the server manages synchronization without requiring direct peer-to-peer communication between devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A first user device may be included in a user device group including the first user device and a second user device that share a same service identifier for a communication service. The method may include accepting user input at the first user device to activate an operation mode for the first user device. Responsive to accepting the user input to activate the operation mode at the first user device, the operation mode may be activated at the first user device. Responsive to accepting the user input to activate the operation mode at the first user device, a notification regarding activation of the operation mode may be transmitted to a control server that is remote from the first user device. Related user devices and control servers are also discussed.
