MTC Trigger Transmission in 3GPP Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 3GPP network architecture lacks an effective solution for processing and transmitting Machine Type Communication (MTC) device trigger information, which is essential for controlling MTC device communication, especially when the IP address of the MTC device is unavailable, leading to network failures in triggering MTC devices.
Innovation Solution
A method and system for sending MTC device trigger information in the 3GPP network, where an MTC server sets the contents of the trigger information, including an MTC device ID and validity period, and sends it to a network node equipment, which searches and forwards it to the core network equipment, ultimately delivering it to the target User Equipment (UE) via the Radio Access Network (RAN), with acknowledgement and potential retransmission mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MTC device trigger information is sent via control plane signaling through existing 3GPP network nodes, then the network can establish communication with MTC devices, but the network lacks effective processing capability for trigger information leading to transmission failures
Solution Approach 1:
The patent introduces a new network node specifically designed to handle MTC device trigger information, acting as an intermediary between the existing 3GPP core network and MTC devices. This specialized node provides the missing processing capability while maintaining compatibility with existing network infrastructure, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The patent segments the MTC trigger information transmission function from the existing general-purpose control plane signaling path. By creating a dedicated function or node for MTC trigger handling, the system separates the specialized MTC processing requirements from the general network operations, enabling reliable MTC-specific processing without affecting existing network functionality.
2Device complexity
If the existing 3GPP network architecture is used without modifications, then network complexity is minimized, but the network cannot effectively process and transmit MTC device trigger information
Solution Approach 1:
The patent introduces a new network node specifically designed to handle MTC device trigger information, acting as an intermediary between the existing 3GPP core network and MTC devices. This specialized node provides the missing processing capability while maintaining compatibility with existing network infrastructure, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The patent designs the new network node or function to be multi-functional, handling various MTC trigger information processing tasks including message routing, device identification, and trigger execution. This universal approach allows the addition of MTC capability without requiring multiple specialized components, thus adding minimal complexity while achieving reliable MTC trigger processing.

AI summary
A method and system for sending Machine Type Communication (MTC) device trigger information and target user equipment is disclosed. An MTC server sets contents of MTC device trigger information, and sends the received MTC device trigger information to a network node equipment. The network node equipment searches a core network equipment corresponding to a target user equipment, and sends the received MTC device trigger information to the core network equipment. The core network equipment forwards the MTC device trigger information to the target user equipment via a radio access network. The target user equipment receives the MTC device trigger information, and sends an MTC device trigger information acknowledgement message to the core network equipment. Through the solution of the disclosure, the sending of MTC device trigger information in a 3GPP network can be realized.
