Title
(EN) DEVICES AND METHODS FOR HANDLING PRECISE TIMING PROTOCOL FRAMES
(FR) DISPOSITIFS ET PROCÉDÉS PERMETTANT DE GÉRER DES TRAMES DE PROTOCOLE DE SYNCHRONISATION PRÉCISE
Abstract
(EN)
A method performed by a transmitting device, in a 3GPP wireless communication 5system (100), for handling generalized Precise Timing Protocol (gPTP) signaling, from a Time Sensitive Network (TSN) is provided. The transmitting device receives (1301) a gPTP frame from the TSN network. The gPTP frame comprises time information, an indication of a time domain related to the time information and/or a Medium Access Control (MAC) address of a second end station connected to a receiving device. Based 10on the indication of the time domain and/or the MAC address, the transmitting device determines (1302) the receiving device which the gPTP frame relates to. The transmitting device transmits (1304), to the determined receiving device, the gPTP frame in a PDU session related to the determined receiving device.

L'invention concerne un procédé mis en oeuvre par un dispositif de transmission, dans un système de communication sans fil 3GPP (100), permettant de gérer une signalisation de protocole de synchronisation précise généralisée (gPTP), à partir d'un réseau sensible au temps (TSN). Le dispositif de transmission reçoit (1301) une trame gPTP provenant du réseau TSN. La trame gPTP comprend des informations temporelles, une indication d'un domaine temporel associé aux informations temporelles et/ou une adresse de commande d'accès au support (MAC) d'une seconde station d'extrémité connectée à un dispositif de réception. Sur la base de l'indication du domaine temporel et/ou de l'adresse MAC, le dispositif de transmission détermine (1302) le dispositif de réception auquel se rapporte la trame gPTP. Le dispositif de transmission transmet (1304), au dispositif de réception déterminé, la trame gPTP dans une session PDU associée au dispositif de réception déterminé.
