TSN Port Configuration via Stream Filter Instance Segmentation
Solution Overview
Problem
Current 5G network integration with Time Sensitive Networking (TSN) protocols faces challenges in managing Ethernet port parameters efficiently, particularly in supporting per-instance parameter handling for stream filter instance tables, which is essential for effective port configuration and management.
Innovation Solution
The solution involves populating stream filter instance values in a stream filter instance table and setting feature support information elements in messages to indicate whether per-instance parameter handling is supported, enabling efficient configuration and management of Ethernet ports in 5G networks through TSN translators and application functions.

Engineering Contradiction Analysis
1Manufacturing precision
If per-instance parameter handling is implemented for stream filter instance tables, then port configuration precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the parameter handling by introducing instance identifiers that uniquely identify each stream filter instance. This allows per-instance parameter management through segmented configuration messages that include instance identifiers, enabling precise control of individual instances without managing the entire table as a single unit, thus improving configuration precision while keeping device complexity manageable through structured segmentation.
Solution Approach 2:
The patent applies local quality by enabling different parameter configurations for different instances within the same stream filter instance table. Each instance can have its own specific parameters (such as different stream filter settings) while sharing the same table structure. This allows localized precision in parameter configuration without requiring complete redesign of the overall system architecture.
2Productivity
If per-instance parameter handling is implemented for stream filter instance tables, then port management efficiency is improved, but message protocol complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-defining the instance identifier field and its encoding format in the message protocol. The instance identifier is prepared as a standardized element that can be directly inserted into configuration messages. This preliminary structuring of the protocol allows efficient per-instance parameter handling without requiring complex runtime processing or ad-hoc message construction, thus improving port management efficiency while controlling protocol complexity through advance planning.

AI summary
Methods, systems, apparatuses, and computer program products are provided for managing configuration of ports of an entity in a device or a mobile communication system, and to facilitate integration of the device and the mobile communication system with a time sensitive networking (TSN) network. A feature support information element may be set to indicate whether per-instance parameter handling of a stream filter instance table is supported by an entity, such as a TT including a device side TSN translator (DS-TT)/network side (NW-TT), and/or network function such as a TSN application function (TSN AF). Accordingly, a stream filter instance value for at least one, or each, stream filter instance of a stream filter instance table may be populated by a TT or TSN AF and sent to the other of the TT or TSN AF.
