C.1 Support for TSC services

23.5453GPPApplication layer support for Factories of the Future (FF)Release 18TS

C.1.1 General

The FF application layer utilizes the SEAL services to support for TSC services which include TSC stream resource management and TSN Bridge resource management.

C.1.2 TSC stream resource management

C.1.2.1 TSC stream availability discovery

In the TSC stream availability discovery procedure, the FF application layer entity discover the availability of resources for TSC communication for the given stream specification (i.e., between the target FF UEs) prior to creating the stream.

The following steps of TSC stream resource management service apply for the FF application layer entity:

– Send the TSC stream availability discovery request specified in clause 14.3.2.23 of 3GPP TS 23.434 [5];

– Receive the TSC stream availability discovery response specified in clause 14.3.2.24 of 3GPP TS 23.434 [5];

The usage of the above information flows is clarified as below:

– The Requester Identity works as FAE Server ID/ FASS ID;

– Stream specification works as MAC addresses of the source and destination DS-TT ports of FF UEs;

C.1.2.2 TSC stream creation

In the TSC stream creation procedure, the FF application layer entity create the stream to establish TSC connectivity with the required QoS between the FF UEs connected to the 5GS after the stream discovery procedure.

The following steps of TSC stream resource management service apply for the FF application layer entity:

– Send the TSC stream creation request specified in clause 14.3.2.25 of 3GPP TS 23.434 [5];

– Receive the TSC stream creation response specified in clause 14.3.2.26 of 3GPP TS 23.434 [5];

The usage of the above information flows is clarified as below:

– The Requester Identity works as FAE Server ID/ FASS ID;

– The VAL Stream ID works as identity of FF stream;

– Stream specification works as MAC addresses of the source and destination DS-TT ports of FF UEs;

C.1.2.3 TSC stream deletion

In the TSC stream deletion procedure, the FF application layer entity delete a TSC stream.

The following steps of TSC stream resource management service apply for the FF application layer entity:

– Send the TSC stream deletion request specified in clause 14.3.2.27 of 3GPP TS 23.434 [5];

– Receive the TSC stream deletion response specified in clause 14.3.2.28 of 3GPP TS 23.434 [5];

The usage of the above information flows is clarified as below:

– The VAL Stream ID works as identity of FF stream;

C.1.3 TSN Bridge resource management

C.1.3.1 TSN Bridge information reporting

In the TSN Bridge information reporting procedure, the FF application layer entity acting as TSN CNC to get TSN Bridge information report.

The following steps of TSN Bridge resource management service apply for the FF application layer entity:

– Get the TSN Bridge information report specified in clause 14.3.2.29 of 3GPP TS 23.434 [5];

– Return the TSN Bridge information reporting specified in clause 14.3.2.30 of 3GPP TS 23.434 [5];

C.1.3.2 TSN Bridge configuration

In the TSN Bridge configuration procedure, the FF application layer entity acting as TSN CNC to get TSN Bridge configuration.

The following steps of TSN Bridge resource management service apply for the FF application layer entity:

– Send the TSN bridge configuration request specified in clause 14.3.2.31 of 3GPP TS 23.434 [5];

– Receive the TSN bridge configuration response specified in clause 14.3.2.32 of 3GPP TS 23.434 [5];
