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).
Claims18
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 at least one of a valid time, a time domain for a time synchronization service, a generic public subscription identifier (GPSI), an external group ID, or a synchronization clock domain;
- generating a synchronization activation request message based on the synchronization information;
- receiving, from a policy control function (PCF), a notification message indicating a packet data unit (PDU) session;
- and
- transmitting, to at least one of a user equipment (UE) and a user plane function (UPF), the synchronization activation request message,
- wherein the synchronization activation request message includes at least one of an international mobile subscriber identity (IMSI), an internal group ID, or a grandmaster (GM) clock domain,
- wherein the IMSI is transformed from the GPSI,
- wherein the internal group ID is transformed from the external group ID, and
- wherein the GM clock domain is transformed from the synchronization clock domain.
