MARS Gateway for SIM-less IoT Data Convergence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile network technologies face challenges in integrating Internet of Things (IoT) devices without Subscriber Identity Modules (SIMs) into mobile networks, as these devices cannot authenticate and send data directly to mobile operators, limiting the ability of telecom operators to account for and monetize IoT data.
Innovation Solution
The implementation of a Machine to Machine (M2M) Aggregation Routing Services (MARS) system that collects data from SIM-less IoT devices, authenticates them through an AAA server, and establishes GPRS Tunnel Protocol (GTP) tunnels with the mobile core network, enabling the processing of IoT data by mobile operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If SIM-less IoT devices connect directly to public networks, then device deployment flexibility is improved, but mobile operators cannot authenticate or account for these devices
Solution Approach 1:
The patent introduces a gateway device as an intermediary between SIM-less IoT devices and the mobile network. The gateway performs authentication with the mobile operator on behalf of multiple IoT devices, enabling devices without SIM cards to access mobile network services while maintaining operator control and billing capability.
2Adaptability or versatility
If IoT devices without SIMs are integrated into mobile networks, then network coverage for IoT devices is improved, but device complexity increases due to additional authentication mechanisms
Solution Approach 1:
The patent combines multiple authentication and billing functions into a single gateway device. Instead of each IoT device requiring individual SIM cards and authentication mechanisms, the gateway consolidates these functions, reducing the complexity at the device level while maintaining comprehensive network coverage.
3Measurement precision
If GTP tunnels are established for each service type, then data routing precision is improved, but network device complexity increases
Solution Approach 1:
The patent segments data traffic into different service types (e.g., S2a, S2b, S2c) and establishes separate GTP tunnels for each service type. This segmentation enables precise routing of different data streams through appropriate network paths while maintaining manageable complexity through standardized tunnel protocols.
Data Source
AI summary
A method in a network device is described and includes selecting, based upon a service request, one or more device gateways from a plurality of device gateways that are communicatively coupled with a plurality of low powered devices. The low powered devices do not include Subscriber Identity Modules. Configuration information is transmitted over a public network to the selected device gateways, causing the selected device gateways to configure ones of the low power devices to perform actions according to the service request. Data is received from the selected device gateways over the public network that was generated by the configured low power devices. One or more GPRS Tunnel Protocol (GTP) tunnels are established with a Packet Data Network (PDN) gateway of a mobile network operator, and the received data is sent over the one or more GTP tunnels to be processed by the mobile network operator.
