Non-IP Data Communication via Header Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in efficiently transmitting non-Internet Protocol (IP) data over packet data networks, particularly in cellular Internet of Things (CIoT) communications, due to overhead issues with IP headers and the need for additional processing and memory resources in wireless devices, which can be costly and resource-intensive.
Innovation Solution
A method and system for communicating non-IP data over packet data networks by removing IP headers from packets and transmitting header-less payload packets, allowing for efficient communication without the use of TCP/UDP/IP headers, while maintaining compatibility with existing EPC standards and allowing parallel communication channels using both IP and non-IP headers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If IP headers are used for communication over packet data networks, then communication compatibility and routing are ensured, but overhead transmission increases and resource consumption rises
Solution Approach 1:
The patent extracts and removes the IP header from the packet structure, transmitting only the payload data over the radio interface. The core network gateway node handles header removal/addition, allowing the wireless device to communicate without implementing full IP stack functionality, thereby reducing overhead transmission while maintaining compatibility through gateway-mediated communication.
Solution Approach 2:
The core network gateway node acts as an intermediary between the wireless device and the packet data network. It adds IP headers when forwarding data to application servers and removes them when receiving data from the wireless device, enabling compatibility mediation without requiring the wireless device to implement complex IP processing.
2Ease of operation
If IP stack and UDP/TCP stacks are implemented in wireless devices, then communication functionality is enabled, but device cost and resource requirements increase
Solution Approach 1:
The patent extracts the IP header processing functionality from the wireless device and relocates it to the core network gateway node. The wireless device only needs to transmit header-less payload packets, eliminating the need for complex IP stack implementation while maintaining communication functionality through the gateway's header management capabilities.
3Loss of energy
If header compression schemes are used, then IP header overhead is reduced, but IP headers still need to be transmitted to set up compression
Solution Approach 1:
The patent removes IP headers entirely from the radio interface transmission, eliminating both the header overhead and the need for header compression setup. Instead of compressing headers, the system transmits only the essential payload data, with the core network gateway node reconstructing full IP packets when needed for network routing.

AI summary
There is provided mechanisms for communicating non-IP data over a PDN of PDN type IPv4, IPv6, or IPv4IPv6. A method is performed by a core network gateway node. The method comprises communicating IP packets over a packet data network of PDN type IPv4, IPv6, or IPv4IPv6 with an application server, the IP packets comprising an IP header and being addressed to a wireless device. The method comprises communicating header-less payload packets over the packet data network with the wireless device. The header-less payload packets correspond to the IP packets having the IP header removed and represent the non-IP data.
