Abstract
A method of a user equipment (UE) in a communication system for obtaining and transmitting synchronization information is provided. The method includes obtaining synchronization information from a first communication network, and transmitting the synchronization information to a second communication network. The synchronization information is updated based on an obtainment time from the first communication network and a transmission time to the second communication network. The UE operates as a device-side time sensitive networking (TSN) translator (DS-TT).
Claims20
A method of a network exposure function (NEF) in a communication system, the method comprising:
- receiving, from an application function (AF), a synchronization information including a valid time and a time domain for a time synchronization service;
- generating a synchronization activation request message based on the synchronization information;
- receiving, from a policy control function (PCF), a notification message indicating a PDU session, and
- transmitting, to at least one of a user equipment (UE) and a user plane function (UPF), the synchronization activation request message.
A method of a user equipment (UE) in a communication system, the method comprising:
- transmitting a packet data unit (PDU) session request message to a network entity of a first communication network;
- receiving a synchronization activation request message from the network entity in response to the PDU session request message, based on a valid time for a time synchronization service;
- generating a synchronization message based on the synchronization activation request message;
- and
- transmitting the synchronization message to a communication node of a second communication network.
A method of a user plane function (UPF) in a communication system, the method comprising:
- transmitting a packet data unit (PDU) session request message to a network entity of a first communication network;
- receiving a synchronization activation request message from the network entity in response to the PDU session request message, based on a valid time for a time synchronization service;
- generating a synchronization message based on the synchronization activation request message;
- and
- transmitting the synchronization message to a communication node of a second communication network.
A method of a network entity in a communication system, the method comprising:
- receiving a packet data unit (PDU) session request message from a UE of a first communication network;
- generating a synchronization activation request message in response to the PDU session request message;
- transmitting the synchronization activation request message to the UE and a UFP based on a valid time for a time synchronization service.
