Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional mobile device management systems require direct internet connectivity, which is not feasible for all electronic devices lacking broadband communication modules, leading to inaccessible device management services and associated communication charges and service delays.

Innovation Solution

A method and system that utilize a wireless terminal with internet connectivity to establish a Device Management (DM) session with an electronic device, allowing the wireless terminal to act as a mobile DM server, enabling the transmission of a Device Description File (DDF) and generating Management Objects (MOs) for managing the device, thereby providing OMA DM services without direct internet connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If electronic devices are directly connected to the DM server through the wireless internet network, then the device management service can be provided, but electronic devices without broadband communication modules cannot access the service

Engineering Contradiction:

Improveaccessibility of DM serviceVSAvoidbroadband communication module requirement

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A wireless terminal with broadband communication capability is introduced as an intermediary between electronic devices without internet access and the DM server. The wireless terminal establishes a DM session with the electronic device, receives the DDF, generates MOs, and transmits them to the DM server, enabling devices without broadband modules to access DM services indirectly through the intermediary terminal

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If electronic devices are directly connected to the DM server through the wireless internet network, then the device management service can be provided, but communication charges and service delays occur

Engineering Contradiction:

Improvedevice management service efficiencyVSAvoidcommunication cost and time

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The wireless terminal acts as a local DM server for electronic devices in proximity, eliminating the need for these devices to establish direct broadband connections to the internet-based DM server. This intermediary approach reduces communication costs and service delays by handling DM operations locally through the terminal's existing internet connection

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The wireless terminal provides DM services to nearby electronic devices using its own broadband communication capability and internet access. The terminal independently establishes DM sessions, receives DDFs, generates MOs, and communicates with the DM server, enabling electronic devices to receive DM services without consuming their own broadband resources or incurring additional communication charges

Inventive Principle:

Principle #25Self-service
