Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current device management protocols lack standardized interfaces for communication between M2M servers and DM servers, requiring custom developments for each service provider, limiting efficiency and interoperability, and do not support enhanced group management operations in an end-to-end architecture.

Innovation Solution

Introduce new message formats and resource attributes for group management procedures to standardize the interface between the service layer and management layer, enabling group-on-group operations and interoperability among different device management protocols.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If custom API interfaces are developed for each service provider to support different device management protocols, then interoperability between systems is limited, but the ability to communicate with specific device protocols is achieved

Engineering Contradiction:

Improveprotocol compatibilityVSAvoidinterface complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a universal service layer interface that can handle multiple device management protocols (OMA DM, OMA LWM2M, BBF CWMP) through a single standardized API. The service layer acts as a protocol-agnostic intermediary that translates between the standardized interface and protocol-specific implementations, eliminating the need for separate custom interfaces for each protocol while maintaining full protocol compatibility

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The service layer serves as an intermediary component between the application layer and the device management protocols. It provides a standardized interface that mediates all communications, translating generic service layer commands into protocol-specific operations. This mediator approach allows the system to work with multiple protocols without requiring custom interfaces for each one

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If individual device management is used following traditional DM protocols, then existing protocols can be maintained, but group management operations are not supported

Engineering Contradiction:

Improvegroup management capabilityVSAvoidmanagement efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent merges individual device management capabilities with group management functionality into a unified framework. The service layer enables batch operations that can simultaneously manage multiple devices by combining their individual management operations into single group-level commands. This allows existing protocol mechanisms to be leveraged while adding efficient group management capabilities

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent adds a group management dimension to the traditional individual device management model. By introducing group-level abstractions in the service layer, the system can operate at both individual device level and group level, enabling efficient bulk operations without sacrificing individual device control capabilities. This dimensional extension allows simultaneous management of multiple devices through group operations

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If standardized interfaces are introduced between service layer and management layer, then interoperability is enhanced, but development complexity increases

Engineering Contradiction:

ImproveinteroperabilityVSAvoidimplementation ease

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent segments the system into distinct layers with clear responsibilities: the service layer provides standardized interfaces, while protocol-specific implementations are separated into independent modules. This segmentation allows the standardized interface to be developed once and reused across multiple protocols, reducing overall implementation complexity despite the added standardization layer

Inventive Principle:

Principle #1Segmentation

AI summary

The present application is directed to a computer-implemented device and method for performing group-on-group operations over the M2M interface. The device and method includes the step of receiving a request to initiate the group-on-group operation from a device owner including commands of a group resource defined in a uniform resource indicator. The device and method includes the step of processing the request and also a step for sending a group management request API to a management server to execute the commands on the devices. Further, there is a step of receiving a response from the management server indicating execution status of the commands by the device. The application also is directed to a computer-implemented method for establishing group-on-group operation over the M2M interface.
