Core Network Entity IP Routing Information Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 5GS DetNet Node lacks a mechanism to learn IP routing information of all its interfaces, which is essential for effective interaction with the DetNet controller and ensuring deterministic transmission capabilities.
Innovation Solution
A core network entity within the 5GS DetNet Node obtains IP routing or forwarding information from user plane, control plane entities, or an IP router controller, and determines updated routing information based on this data and preconfigured static routing information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the TSCTSF reports routing information to the DetNet controller, then the DetNet controller can manage routing, but the TSCTSF cannot learn IP routing information of all interfaces
Solution Approach 1:
The patent introduces a core network entity as an intermediary that collects IP routing information from multiple interfaces and forwards it to the TSCTSF. This mediator approach allows the TSCTSF to obtain complete routing information without directly managing all interfaces, resolving the contradiction between information completeness and system complexity.
Solution Approach 2:
The patent segments the routing information collection function by separating it from the TSCTSF and assigning it to a dedicated core network entity. This segmentation allows each component to focus on specific tasks: the core network entity collects and aggregates routing information from all interfaces, while the TSCTSF processes and reports only the necessary routing information to the DetNet controller.
2Reliability
If the core network entity determines routing information based on static routing information, then routing control is maintained, but adaptability to dynamic routing changes is reduced
Solution Approach 1:
The patent implements dynamics by allowing the core network entity to receive and process dynamic routing information from multiple interfaces while maintaining static routing information for control. The system can switch between static and dynamic routing modes or combine both approaches, enabling flexible adaptation to changing network conditions while preserving stable control when needed.
Solution Approach 2:
The patent changes the parameter of routing information processing by introducing a core network entity that can process both static and dynamic routing information. This allows the system to adjust routing behavior based on current network conditions while maintaining the ability to enforce stable routing control through preconfigured static information.

AI summary
Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for IP routing and forwarding operation and management of an IP router node. A core network entity obtains a first set of IP routing or forwarding information about at least one IP interface in a first IP router node from at least one of the following: at least one user plane entity in the first IP router node, at least one control plane entity in the first IP router node, or an IP router controller. In turn, the core network entity determines a second set of IP routing or forwarding information about the first IP router based on at least one of the first set of IP routing or forwarding information and first static routing information preconfigured on the core network entity, the at least one IP interface connecting the first IP router node to a second set of IP entities and/or to a third set of IP entities. Each of the IP entities comprises an IP node or an IP host.
