Terminal Device Capability Management Object Maintenance

Solution Overview

Problem

Current Device Management Systems (DMS) face inefficiencies in managing device capability updates, leading to wastage of wireless transmission resources, increased processing payloads, and delays due to the need for frequent reporting and processing of updated capability information from terminal devices.

Innovation Solution

The terminal device autonomously detects and maintains updated Device Capability Management Objects (DCMO) within its Device Management tree, reducing the need for the DMS to generate and transmit updated DCMOs, thereby conserving wireless resources and processing loads, and enabling timely management of changed capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the terminal device reports changed capability information to the DMS for generating and transmitting updated DCMO, then the DMS can manage device capabilities accurately, but wireless transmission resources are wasted and processing payloads increase

Engineering Contradiction:

Improvecapability management accuracyVSAvoidwireless transmission resource wastage

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The terminal device autonomously detects changed capability information and maintains updated DCMO itself without requiring DMS intervention. The terminal device compares current capability information with stored DCMO, identifies changes, and generates updated DCMO locally, thereby eliminating the need for wireless transmission of capability information and reducing processing payloads at the DMS.

Inventive Principle:

Principle #25Self-service

2Reliability

If the terminal device reports changed capability information to the DMS for generating and transmitting updated DCMO, then the DMS can manage device capabilities accurately, but processing payloads at DMS increase

Engineering Contradiction:

Improvecapability management accuracyVSAvoidDMS processing payload

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The terminal device autonomously detects changed capability information and maintains updated DCMO itself without requiring DMS intervention. The terminal device compares current capability information with stored DCMO, identifies changes, and generates updated DCMO locally, thereby eliminating the need for wireless transmission of capability information and reducing processing payloads at the DMS.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If the terminal device waits for DMS to generate and transmit updated DCMO after capability changes, then the DMS can provide centralized control, but delays occur in managing changed capabilities

Engineering Contradiction:

Improvecentralized control capabilityVSAvoidcapability update delay

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The terminal device performs preliminary actions by autonomously detecting capability changes and generating updated DCMO before DMS intervention is needed. The terminal device maintains a local copy of DCMO and proactively updates it when capability changes are detected, eliminating waiting time for DMS processing and transmission while preserving the ability to report changes to DMS for centralized control when needed.

AI summary

A method for maintaining a Device Capability Management Object (DCMO) which relates to technical field of Open Mobile Alliance Device Management (OMA DM), including detecting changed capability information in a terminal device by the terminal device, and maintaining a corresponding Device Capability Management Object in a Device Management tree in the terminal device based on the detected changed capability information, is used to overcome that wireless transmission resources are wasted and processing payloads of a Device Management Server (DMS) system are increased when updating and maintaining the corresponding Device Capability Management Object once capability information in the terminal device changes.
