Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In Machine To Machine (M2M) communication, the MTC Server cannot realize real-time control and intelligent control of MTC UE due to its inability to acquire information from the underlying access layer, and acquiring this information from the core network poses security threats.

Innovation Solution

A method and system where an MTC Gateway (MTC GW) acquires information from the mobility management network element and sends it to the MTC Server, enabling the MTC Server to access information about the MTC UE's subscription data, location, and events, while ensuring security by verifying the MTC Server's access rights.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the MTC Server directly acquires information from the core network, then the MTC Server can obtain real-time information of MTC UE, but the security of the core network is threatened

Engineering Contradiction:

Improveinformation acquisition capabilityVSAvoidnetwork security

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an MTC Gateway as an intermediary component between the MTC Server and the core network. The MTC Gateway acquires information from the mobility management network element and selectively provides it to authorized MTC Servers. This mediator architecture allows the MTC Server to obtain necessary information without directly accessing the core network, thereby maintaining security while enabling information flow.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the MTC Server cannot acquire information from the underlying access layer, then the core network remains secure, but the MTC Server cannot perform real-time control and intelligent management

Engineering Contradiction:

Improvecontrol capabilityVSAvoidaccess layer information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The MTC Gateway acts as an intermediary that bridges the information gap between the access layer and the MTC Server. It collects information from the mobility management network element (which has access to subscription data, location, and event information) and makes this information available to the MTC Server through controlled interfaces, enabling real-time control without compromising security.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the information acquisition function into two parts: the MTC Gateway handles the complex task of interacting with the mobility management network element and filtering information, while the MTC Server focuses on using the provided information for control decisions. This segmentation allows each component to specialize in its function, improving overall system reliability and control capability.

AI summary

A method and a system for acquiring information of Machine Type Communication (MTC) user equipment (UE) are provided. The method comprises the steps of: an MTC GateWay (MTC GW) acquiring the information of the MTC UE which currently requests to attach to a network or has attached to a network from a mobility management network element; the MTC GW sending the information of the MTC UE acquired from the mobility management network element to an MTC Server. The method and the system can control the MTC UE in real time and intelligently.
