NB-IoT SIM Card Remote Update via UDP Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for updating SIM card settings in Narrow Band-Internet of Things devices are inefficient due to the lack of MSISDN support and the need for costly high-speed message packages, which are not scalable for the increasing number of IoT devices, and rely on protocols like SMPP and Short Message Services that are difficult to implement without MSISDN.
Innovation Solution
A method for remotely updating SIM card settings in NB-IoT devices using a User Datagram Protocol (UDP) communication channel, which establishes a connection between a configuration data-providing entity and the SIM card, allowing for data exchange without the need for MSISDN, and emulates HTTP-OTA mechanisms to support existing infrastructure.

Engineering Contradiction Analysis
1Productivity
If traditional Over-the-Air services using Short Message Services or HTTP-OTA are used, then SIM card settings can be updated, but costly MSISDN and high-speed message packages are required which are not scalable for huge numbers of IoT devices
Solution Approach 1:
The patent extracts the SIM card update function from the traditional SMS/HTTP-OTA framework that requires MSISDN, and implements it directly over IP using UDP protocol. This separates the configuration update mechanism from the voice/SMS infrastructure, eliminating the need for costly MSISDN allocation while maintaining the ability to update SIM settings remotely.
Solution Approach 2:
The patent introduces a UDP-based communication channel as an intermediary between the configuration data-providing entity and the SIM card. This intermediary replaces the traditional SMS gateway and HTTP-OTA mechanisms, enabling direct data exchange without requiring MSISDN or high-speed message packages, thus resolving the scalability issue.
2Ease of operation
If protocols like SMPP and Short Message Services are used for SIM card configuration, then configuration can be performed, but it becomes difficult to send messages without MSISDN and requires costly high-speed message packages
Solution Approach 1:
The patent substitutes the complex SMS/SMPP protocol stack with a simpler UDP-based IP communication mechanism. Instead of using the traditional SMS message routing infrastructure, the system uses direct UDP datagrams to transmit configuration commands and responses, dramatically simplifying the protocol implementation while maintaining configuration capability.
Solution Approach 2:
The patent extracts the configuration update function from the SMS/SMPP protocol framework and implements it independently over IP/UDP. This separation allows the system to perform SIM card configuration without relying on the complex SMS infrastructure, eliminating the need for MSISDN and reducing protocol complexity.
3Use of energy by moving object
If NB-IoT devices are made lightweight without voice transmission capability, then resource consumption is reduced, but MSISDN cannot be assigned making traditional OTA updates difficult
Solution Approach 1:
The patent changes the communication parameter from SMS-based (requiring MSISDN) to IP-based UDP communication. This parameter change enables NB-IoT devices to receive configuration updates without voice capability or MSISDN assignment, maintaining lightweight resource consumption while achieving compatibility with remote update services.
Solution Approach 2:
The patent introduces a UDP communication channel as an intermediary that bridges the configuration data-providing entity and the SIM card in NB-IoT devices. This intermediary enables OTA updates for lightweight devices without voice capability, as UDP can operate over IP without requiring MSISDN or voice transmission infrastructure.
