Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing MTC event management systems face challenges in providing proactive and efficient Command and Control (CnC) functionality due to resource constraints and the non-spontaneous adaptation of network topology, often resulting in delayed activation of CnC VNFs, which can be too late to effectively mitigate critical MTC events.

Innovation Solution

The method involves mapping MTC event states to VNF lifecycle states, enabling proactive instantiation and activation of CnC VNFs before events reach critical levels, using techniques such as MTC event correlation, state transition probability analysis, and dynamic VNF lifecycle management to optimize resource usage and ensure timely response.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If CnC VNFs are activated only after MTC events reach critical levels, then resource usage is minimized, but response time becomes too late to effectively mitigate critical events

Engineering Contradiction:

Improveeffectiveness of event mitigationVSAvoidactivation delay of CnC VNFs

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by mapping MTC event states to VNF lifecycle states and proactively instantiating CnC VNFs before events reach critical levels. The Event Management Entity monitors event states and triggers VNF instantiation in advance, ensuring the VNFs are ready to mitigate events before they become critical, thus resolving the contradiction between early activation and resource efficiency.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms by continuously monitoring MTC event states and using this information to dynamically control VNF lifecycle states. The Event Management Entity receives event state data, determines appropriate VNF states based on mapping relationships, and adjusts VNF instantiation accordingly, creating a closed-loop control system that optimizes both response time and resource usage.

Inventive Principle:

Principle #23Feedback

2Loss of time

If CnC VNFs are proactively instantiated before events reach critical levels, then response time is improved, but resource consumption increases

Engineering Contradiction:

Improveactivation delay of CnC VNFsVSAvoidresource consumption for VNF instantiation

Core Design Contradiction:

Loss of timeVSUse of energy by moving object

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system applies dynamics by making the VNF instantiation state dynamic and adaptive based on real-time MTC event conditions. Rather than static pre-instantiation or reactive activation, the VNF lifecycle state changes dynamically in response to monitored event states, optimizing resource usage while maintaining readiness to respond to critical events.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If comprehensive VNF catalogues are maintained for all possible MTC events, then adaptability is improved, but storage requirements increase

Engineering Contradiction:

Improvecoverage of MTC event typesVSAvoidstorage space in VNF catalogues

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system applies universality by creating a general mapping framework between MTC event states and VNF lifecycle states that can handle diverse event types without requiring separate catalogues for each event. The Event Management Entity uses this universal mapping relationship to appropriately instantiate VNFs based on the specific event state, reducing storage requirements while maintaining adaptability across different MTC event scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

There is provided a method and system for management of Machine Type Communication (MTC) events. The system and method enables the detection of a state of the MTC event, correlating the state of MTC event with a Virtual Network Function (VNF) state of a VNF configured to mitigate the MTC event and transitioning the VNF to the VNF state which correlates with the MTC state. In this manner, the VNF can be in a configured and active state in advance of the MTC event reaching a critical state, thereby enabling mitigation of the MTC event prior to reaching the critical state.
