Solution Overview

Problem

Users often forget to manually establish connections between devices for synchronization, and the required cables are frequently misplaced or lost, making existing synchronization methods inconvenient and unreliable.

Innovation Solution

A wireless communications network architecture that facilitates automatic synchronization based on device presence, using a presence component to detect network registration of a mobile device with a network entity like a femtocell, allowing synchronization to occur automatically when the device is present at a target location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual connection establishment is used for synchronization, then connection reliability is improved, but user convenience deteriorates due to forgotten manual steps and misplaced cables

Engineering Contradiction:

Improveconnection reliabilityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs synchronization automatically without requiring user intervention. The mobile device detects its presence at the target location through network registration with the femtocell, and the synchronization operation is initiated and executed automatically between the mobile device and the remote device, eliminating the need for manual connection establishment.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical cable-based connection system with a wireless communication-based presence detection system. Instead of using physical cables and manual plug-and-play operations, the system uses wireless network registration signals to detect device presence and trigger synchronization automatically.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If automatic synchronization based on device presence is implemented, then user convenience is improved, but system complexity increases due to presence detection mechanisms

Engineering Contradiction:

Improveuser convenienceVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system leverages the existing multi-functional capability of mobile devices to perform both communication (network registration with femtocell) and presence detection functions. The same wireless communication infrastructure used for normal network operations is also used to detect when the device is present at the target location, eliminating the need for separate presence detection hardware.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The femtocell acts as an intermediary that facilitates presence detection. Instead of the mobile device directly detecting its own presence or requiring complex sensor systems, the mobile device's network registration with the femtocell serves as the presence indication, with the femtocell mediating the detection process through standard network signaling.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If presence-based automatic synchronization is used, then synchronization reliability is improved, but loss of time occurs during presence detection and automatic initiation

Engineering Contradiction:

Improvesynchronization reliabilityVSAvoidsynchronization delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs presence detection continuously through ongoing network registration processes. The mobile device maintains network registration status with the femtocell, which provides continuous presence information. This preliminary and continuous detection ensures that synchronization can be initiated immediately when conditions are met, minimizing delay.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from network registration status to determine device presence. The mobile device's registration state with the femtocell provides real-time feedback about whether the device is present at the target location, enabling the synchronization system to respond promptly and reliably without unnecessary delays.

Inventive Principle:

Principle #23Feedback

AI summary

An architecture that can facilitate initiation of an automatic synchronization operation based upon presence information in connection with a wireless communications network is provided. For example, when certain mobile devices register with a particular network entity (e.g., a femtocell) that services a particular target location (e.g., place of residence), then such registration can be leveraged to indicate presence at the target location. Accordingly, synchronization between the mobile device and other devices can be automatically initiated, without requiring input or effort by a user, or even that the user remembers to perform the synchronization operation. Moreover, the synchronization operation can be wireless, so connection cables need not be maintained or employed.
