Classification: CPC H | IPC H

Claim 0:
1. A method of creating a QoS flow for a time synchronization protocol in a wireless communication network, the method comprising:
receiving, by a session management function (SMF), a protocol data unit (PDU) session establishment or modification request comprising at least one of
a data network name (DNN) or
a single network slice selection assistance information (S-NSSAI) fora time sensitive communication (TSC) service;

providing, by the SMF, a Session Establishment or Modification Request including QoS flow information and
an service data function (SDF) filter information for the QoS flow fora time synchronization protocol to a User Plane Function (UPF);

requesting, by the SMF, a policy control function (PCF) to seta PCCrule with at least one of the DNN or the S-NSSAI information;
setting, by the policy control function (PCF), a PCCrule for the QoS flow for the time synchronization protocol considering at least one of the DNN or the S-NSSAI; and
receiving, by the SMF, the PCCrule from the PCF.
