K.2.2.2 Configuration for Sync and Announce reception timeouts
Taught in 22. Clocks, TSN and deterministic delivery (The 5G system architecture, in depth).
The NW-TT shall be able to determine the timeout of the reception of (g)PTP Announce (when the 5GS operates as a time-aware system or Boundary Clock) and gPTP Sync messages (when the 5GS operates as time-aware system). To enable this, the TSCTSF or TSN AF shall configure the NW-TT for the following information via PMIC for each PTP port in NW-TT and "Time synchronization information for each DS-TT port" element in UMIC for each PTP port in DS-TT:
portDS.announceReceiptTimeout (for time-aware system and Boundary Clock);
portDS.syncReceiptTimeout (for time-aware system);
portDS.logAnnounceInterval (for Boundary Clock).
portDS.initialLogAnnounceInterval, portDS.useMgtSettableLogAnnounceInterval and portDS.mgtSettableLogAnnounceInterval (for time-aware system).
