Abstract: A method in which a high-quality packet telephony terminal apparatus performing low-latency and lossless packet communication with a counterpart packet telephony terminal apparatus operates in an integrated network structure in which a time sensitive network (TSN) and a packet communication network are combined may be disclosed. The packet telephony terminal apparatus may perform packet telephony call processing, perform a TSN stream reservation procedure when the counterpart packet telephony terminal apparatus is capable of performing a TSN function for lossless packet communication, adjust a size of a dejitter buffer when the TSN stream reservation procedure is successful, and perform low-latency packet telephony communication through the minimized size of the dejitter buffer.

Abstract: Proposed is an apparatus and method for requesting time-sensitive communication (TSC) management information, wherein the method for directly sending TSC management information in wireless communication systems may include a process of sending TSC management information from TSN AF (time-sensitive network application function) to PCF (policy control function), where TSC management information is composed of at least one of PMIC, a port number, and UMIC, and an address information of a target NF, a process of PCF sending the changed policy information to SMF when there is a change in policy information, where the changed policy information is composed of TSC management information, and a process of requesting TSC management information to be included when the SMF requests PFCP session report from UPF.
