Network Node IP Encapsulation for Non-IP Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing data transmission between user equipment (UE) and data networks (DN), particularly in handling non-IP based networks, where accurate identification and encapsulation of IP addresses are necessary for proper data transmission and reception, leading to issues with ambiguity and overlapping IP addresses.
Innovation Solution
A method is introduced where downlink and uplink data are encapsulated or de-capsulated with IP addresses based on whether the data network is IP-based or non-IP based, using a per-node level tunneling model to ensure accurate transmission and reception of non-IP PDU sessions, and determining the appropriate IP address handling for each type of network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IP address encapsulation is performed for all downlink data regardless of network type, then data transmission to non-IP based networks is enabled, but IP address ambiguity and overlapping occurs
Solution Approach 1:
The patent applies local quality by differentiating IP address handling based on the specific network type. For IP-based networks, IP addresses are not encapsulated, while for non-IP based networks, IP addresses are encapsulated. This localized adaptation to different network characteristics resolves the contradiction between enabling universal data transmission and maintaining IP address accuracy.
2Adaptability or versatility
If IP address encapsulation is performed for non-IP based networks, then data transmission to non-IP networks is enabled, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by determining the network type before data transmission and pre-configuring the appropriate encapsulation method. The system identifies whether the target network is IP-based or non-IP based in advance, and accordingly applies or skips IP address encapsulation. This preliminary determination simplifies the overall process by avoiding complex runtime decisions and unnecessary encapsulation operations.
3Measurement precision
If per-node level tunneling is implemented for accurate data routing, then data transmission accuracy improves, but network configuration complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the network into per-node level tunnels, where each node handles encapsulation and routing independently. This segmentation allows accurate data routing at each node without requiring complex end-to-end tunnel configuration, as each node autonomously determines the appropriate encapsulation method based on the target network type.

AI summary
A method of supporting data transmission of a network node in a wireless communication system includes: receiving downlink data from a Data Network (DN); encapsulating the downlink data with an IP address of an User Equipment (UE) based on whether the DN is an Internet Protocol (IP) based network or a non-IP based network; not encapsulating, if the DN is the IP based network, the received downlink data with the IP address of the UE and encapsulating, if the DN is the non-IP based network, the received downlink data with the IP address of the UE; and transmitting the downlink data encapsulated with the IP address or the downlink data that are not encapsulated with the IP address to an Access Network (AN).
