MTC Preregistration via Group IP and Wake Cycles
Solution Overview
Problem
Current machine-to-machine (M2M) communication systems face challenges in efficient preregistration and management of MTC devices, particularly in scenarios where devices remain untouched for extended periods, leading to potential fraud and costly reconfiguration or replacement when utility providers change.
Innovation Solution
A method and apparatus for MTC preregistration that allows for single or periodic preregistrations, utilizing group Internet Protocol (IP) addresses and synchronized wake-up cycles for control and reporting, enabling network-controlled preregistration and IP allocation, thereby simplifying device access and reducing the need for manual reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices remain untouched for extended periods without preregistration, then device simplicity is maintained, but fraud risk increases and reconfiguration costs rise
Solution Approach 1:
The patent implements preregistration mechanisms that pre-establish network access parameters, IP address allocations, and device identities before devices are deployed or activated. This preliminary configuration reduces fraud risk by ensuring devices are properly registered with network authorities beforehand, while the preconfiguration is stored in simple device memory rather than requiring complex real-time registration systems.
2Adaptability or versatility
If manual reconfiguration is performed when utility providers change, then device-network matching is ensured, but time and cost increase
Solution Approach 1:
The patent enables devices to automatically perform network registration and configuration when utility providers change. Devices self-identify themselves to network authorities using preregistered information, automatically obtain new IP address allocations, and complete reconfiguration without human intervention. This self-service mechanism ensures adaptability to provider changes while eliminating manual reconfiguration time and costs.
3Productivity
If group IP addresses are used for MTC devices, then network access efficiency is improved, but individual device identification becomes more complex
Solution Approach 1:
The patent implements a two-level IP address structure where group IP addresses provide network access for groups of MTC devices, improving efficiency for bulk operations. Simultaneously, individual device identifiers are maintained within the group structure, allowing unique device recognition when needed. This segmentation approach separates the functions of group management and individual identification, reducing overall system complexity while maintaining both efficiency and traceability.

AI summary
A method and apparatus for machine type communication (MTC) preregistration are provided. The methods provide single or periodic preregistrations and may be machine to machine (M2M) application function (AF) or device (MTC user equipment based). The devices in the system may be divided into groups and accessed by on a group Internet Protocol (IP) address. Two wake up cycles may be provided, one for control and one for uploading information (a reporting cycle). During the control cycle, the devices may wake up and listen to the control channel for any paging messages. Depending on the paging information, individual devices or the entire group may access the system. In the reporting cycle, all the devices may wake up and access the system to connect to the M2M system to upload data.
