Solution Overview

Problem

Existing machine-to-machine (M2M) communication systems lack efficient mechanisms for a cellular network node to identify and manage M2M devices, leading to suboptimal network control procedures and data management.

Innovation Solution

A dedicated interface, referred to as the GM2M interface, is established between an M2M server and a cellular network node, such as a Serving GPRS Support Node (SGSN), enabling the node to determine M2M devices based on subscriber data and facilitate network control procedures, including status requests and information exchange.

1Reliability

If a dedicated GM2M interface is established between cellular network node and M2M server, then network control and management of M2M devices is enhanced with precise identification and efficient data communication, but device complexity and network architecture complexity increase

Engineering Contradiction:

Improvenetwork controlVSAvoidnetwork architecture

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The network architecture is segmented by introducing a dedicated GM2M interface that separates M2M device management traffic from general mobile data traffic. This segmentation allows specialized handling of M2M control procedures while maintaining standard interfaces for other services, thus improving reliability without requiring complete architectural redesign.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The GM2M interface acts as an intermediary communication path between the cellular network node and M2M server. This intermediary enables direct, efficient control data exchange for M2M devices without interfering with the broader network architecture, enhancing management capabilities while isolating complexity to a specific interface layer.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If cellular network node determines M2M devices based on subscriber data, then identification precision of M2M devices is improved, but information processing requirements and data management complexity increase

Engineering Contradiction:

Improvedevice identificationVSAvoiddata management overhead

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

Subscriber data is pre-configured with M2M device identification information before the devices connect to the network. This preliminary action allows the cellular network node to immediately recognize and appropriately manage M2M devices upon connection, improving identification precision without requiring complex real-time analysis that would increase data management overhead.

AI summary

A method for triggering a wireless transmit/receive unit (WTRU), for use by a cellular network node, comprises receiving a control plane message associated with the WTRU from a server. The control plane message is received via a control plane interface between the cellular network node and the server. The method comprises sending a message to the WTRU based on the control plane message that requests the WTRU to perform a procedure to enable communication with a Packet Data Network. The method comprises sending an update message to the server via the control plane interface after receiving the control plane message, wherein the update message comprises information associated with the WTRU.
