Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3GPP systems lack the ability to identify and configure suitable user equipment for deterministic network traffic, failing to provide the necessary Quality of Service requirements for layer-3 deterministic networks.
Innovation Solution
Implement procedures for layer-3 deterministic networks in 5G systems by using a wireless communication device to send requests for user plane connections, involving an application function to translate deterministic network flow requirements into Quality of Service requirements, and configuring network functions to establish sessions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 3GPP systems use existing Ethernet/layer-2 based interfaces for Deterministic Network traffic, then layer-2 Deterministic Networks are supported, but layer-3 Deterministic Networks with IP connectivity cannot be supported
Solution Approach 1:
The patent introduces an Application Function (AF) as an intermediary entity that bridges the gap between layer-2 Deterministic Network support and layer-3 IP connectivity requirements. The AF translates layer-3 Deterministic Network flow requirements into layer-2 Quality of Service parameters, enabling IP-based Deterministic Network traffic to be carried over the existing layer-2 infrastructure without requiring direct layer-3 interface support in the radio access network.
2Reliability
If procedures are implemented to establish user plane connections for Deterministic Network traffic, then Quality of Service requirements can be met, but the system lacks functionality to identify and discover suitable user equipment
Solution Approach 1:
The patent implements preliminary action by having the Application Function subscribe to notifications from the Access and Mobility Management Function about user equipment that establishes user plane connections. This allows the system to proactively identify and discover suitable user equipment before Deterministic Network traffic needs to be routed, enabling the controller to prepare appropriate Quality of Service configurations in advance.
3Adaptability or versatility
If the Application Function translates Deterministic Network flow requirements into Quality of Service requirements, then layer-3 Deterministic Network traffic can be relayed, but additional network functions and signaling are required
Solution Approach 1:
The patent applies universality by designing the Application Function to perform multiple roles: it acts as a interface between the Deterministic Network controller and the 3GPP core network, translates layer-3 flow requirements into layer-2 Quality of Service parameters, subscribes to user equipment connection events, and initiates user plane session establishment. This multi-functional approach consolidates several necessary functions into a single network element, reducing overall architectural complexity.
