MARS Gateway for SIM-less IoT Device Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile network technologies are unable to effectively integrate and manage Internet of Things (IoT) devices without a Subscriber Identity Module (SIM) into their networks, limiting the ability to authenticate and account for data from these devices.
Innovation Solution
The implementation of a Machine to Machine (M2M) Aggregation Routing Services (MARS) system that collects data from SIM-less low-powered device gateways, authenticates them through an AAA server, and establishes a GPRS Tunnel Protocol (GTP) tunnel with the mobile core network, allowing for the convergence of IoT data into the mobile network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile network technologies use traditional SIM-based authentication, then device security and network management are maintained, but SIM-less low-powered IoT devices cannot be integrated into the mobile network
Solution Approach 1:
The patent introduces a Low Powered Device Gateway (LPDG) as an intermediary component that bridges SIM-less IoT devices and the mobile network. The LPDG performs authentication and account management functions on behalf of devices without SIM cards, allowing them to access mobile network services while maintaining security and manageability. The gateway acts as a mediator that translates between the simple connection needs of low-powered devices and the complex authentication requirements of the mobile network.
2Ease of operation
If SIM-less gateways are connected directly to the Internet or Cloud systems, then device connectivity is simplified, but telecom operators cannot account for or monetize the data from these devices
Solution Approach 1:
The patent implements a nested architecture where SIM-less IoT devices are nested within the coverage area of Low Powered Device Gateways, which in turn are nested within the mobile operator's network infrastructure, and finally connected to the mobile core network. This multi-layer nesting allows devices to maintain simple local connectivity while being progressively integrated into the operator's billing and management systems at higher levels of the hierarchy.
3Reliability
If a GTP tunnel is established between the LPDG and PDN gateway, then secure data transmission is achieved, but network device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring the GTP tunnel parameters, authentication credentials, and data flow policies before the actual data transmission begins. The network devices are pre-provisioned with the necessary GTP context information, and the LPDG is pre-authenticated with the mobile network, so that when data transmission is initiated, the secure tunnel is already established and ready, minimizing runtime complexity.

AI summary
A method in a network device coupled with a packet data network (PDN) gateway of a mobile operator is described. The method includes transmitting configuration information to a low powered device gateway coupled with a plurality of low powered devices based on a received configuration request, wherein the low powered device gateway does not include a Subscriber Identity Module (SIM). The method further includes communicating with an AAA server to authenticate a selection of the plurality of low powered devices and establishing a GPRS Tunnel Protocol (GTP) tunnel with the PDN gateway. The method further includes receiving from the low powered device gateway collected data from the selection of the plurality of low powered devices and sending to the PDN gateway the collected data.
