Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication systems lack an effective method for acquiring and transmitting Machine Type Communication (MTC) device group identification, which is necessary for determining attributes and selecting Quality of Service (QoS) in network elements.

Innovation Solution

A method and apparatus for acquiring MTC device group identification involve a mobility management network element subscribing to and downloading this identification from a user database through location update messages or subscription data messages, enabling the selection of different QoS for establishing default bears.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If MTC device group identification is not transmitted in the network, then network complexity is reduced, but the ability to determine device attributes and select QoS is lost

Engineering Contradiction:

Improvenetwork complexityVSAvoidQoS selection capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The MTC device group identification is pre-configured in the MTC device before network access. This preliminary action eliminates the need for network transmission of identification information, reducing network complexity while ensuring the identification is available for QoS determination when needed

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The MTC device uses its own pre-stored group identification to determine its attributes and QoS requirements autonomously. This self-service approach eliminates the need for network elements to receive and process identification information, reducing network complexity while maintaining QoS selection capability

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If MTC device group identification is transmitted through location update messages, then QoS selection capability is improved, but signaling overhead increases

Engineering Contradiction:

ImproveQoS selection capabilityVSAvoidsignaling overhead

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The MTC device group identification is merged with the device's internal configuration data rather than being transmitted separately as signaling. This combining approach provides QoS selection capability without increasing signaling overhead, as the identification is already present in the device's stored information

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If different types of default bears are established based on group identification, then service quality is improved, but device complexity increases

Engineering Contradiction:

Improveservice qualityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system changes the parameter of using pre-configured group identification rather than requiring complex real-time analysis of device attributes. This parameter change simplifies the device complexity while maintaining the ability to establish appropriate default bears for different service qualities

Inventive Principle:

Principle #35Parameter changes
