UE Data Transmission Switching from Non-IP to Dynamic IP
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for machine-to-machine communication in cellular networks face challenges with dynamic IP addresses, as they rely on SMS for data transmission, which is not available in 5G NB-IoT networks, leading to increased costs and unnecessary data traffic.
Innovation Solution
A method enabling server-initiated data transmission using a dynamic IP address by switching from Non-IP to IP communication upon receiving a paging and RLC message, allowing data transfer without SMS capability, particularly suitable for 5G NB-IoT networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If SMS is used to trigger data transmission from user equipment with dynamic IP address, then the application server can initiate data transfer, but the solution is not available in 5G NB-IoT networks without SMS capability
Solution Approach 1:
The patent introduces a Non-IP communication protocol stack as an intermediary mechanism between the application server and user equipment. This stack includes a paging message and RLC message that can convey IP address information and trigger data transmission without requiring SMS capability, thus enabling 5G NB-IoT network compatibility while maintaining reliable server-initiated data transfer
Solution Approach 2:
The patent changes the communication parameter from SMS-based triggering to Non-IP protocol stack-based triggering. By modifying the message format and communication mechanism (using paging messages with embedded IP address information instead of SMS), the system achieves compatibility with networks that lack SMS capability while preserving the ability to initiate data transmissions
2Productivity
If a fixed IP address is used for the user equipment, then the application server can take data on demand, but the customer is charged with extra fees and periodic connections generate unnecessary data traffic
Solution Approach 1:
The patent employs dynamic IP address assignment combined with on-demand connection establishment. Instead of using a fixed IP address that requires continuous or periodic connections, the system dynamically assigns IP addresses only when data transmission is needed, triggered by the application server through the Non-IP protocol stack. This eliminates unnecessary data traffic and reduces operational costs while maintaining efficient data retrieval capability
Solution Approach 2:
The user equipment automatically obtains IP address information and establishes connections when triggered by the paging message containing the application server's IP address. The equipment self-manages the connection lifecycle without requiring periodic polling or fixed IP assignment, thereby eliminating wasteful data traffic while enabling on-demand data retrieval

AI summary
The present invention relates a user equipment UE registered for Non-IP communication services performs an application function. For providing application data via a radio access network, a method involves receiving a paging message and a subsequent radio link control, RLC, message in accordance with a Non-IP communication protocol. The paging message and the RLC message are initiated by an application server associated with the application function. The UE retrieves a network address of the application server in accordance with an IP communication protocol stack, and activates use of the IP communication protocol stack. The UE then requests IP communication services from the core network via the wireless cellular network, obtains a dynamic network address in accordance with the Internet Protocol and uses its dynamic network address and the network address of the application server to providing the application data to the application server using the IP communication services via the wireless cellular network.
