Abstract:
An apparatus and method for directly exposing, by user plane function/network side-time sensitive networking translator (UPF/NW-TT), event result information to time sensitive networking (TSN) or time sensitive communication time synchronization function (TSCTSF) through service interface (Nupf) in wireless communication system. A method of operating event processing for TSN or TSC includes: when policy control function (PCF) performs TSC event subscription, receiving TSC management and control information for direct reporting notification of event result from TSN-application function or TSCTSF and transmitting the TSC management and control information to session management function (SMF); regenerating the TSC management and control information and transmitting the regenerated TSC management and control information to UPF/NW-TT through N4 interface; and receiving the TSC management and control information from SMF, and when a corresponding event occurs, transmitting the TSC management information including the event result to a target in the control information through SBI.
Abstract:
The present disclosure relates generally to a wireless communication system. More particularly, the present disclosure relates to an apparatus and a method for performing a session management event exposure service for user data monitoring in a wireless communication system.
Abstract:
Provided is an operation method of a user plane function (UPF) apparatus in a wireless communication system, the operation method including: obtaining a subscription request message from either a TSN AF or a TSCTSF or both on the basis of an exposure service for a UPF event, the subscription request message including TSC management information; performing triggering for subscription to the UPF event on the basis of the TSC management information; and providing a notification message to either the TSN AF or the TSCTSF or both, the notification message including the TSC management information.
Abstract:
Provided is a method of jitter monitoring for time sensitive communication (TSC) in a wireless communication network. The method of jitter monitoring may include: receiving, by a user plane function (UPF), a delay and jitter measurement request from an application function (AF); measuring, by the UPF, a delay and a jitter in response to the delay and jitter measurement request; and transmitting, by the UPF, the measured delay and jitter to the AF.
Abstract:
The present disclosure relates generally to a wireless communication system. More particularly, the present disclosure relates to an apparatus and a method for providing setting information on a time-sensitive networking talker and listener for time-sensitive networking (TSN) transport in a wireless communication system. According to various embodiments of the present disclosure, provided is a method of giving notification of whether a radio access network (RAN) supports a time-sensitive networking (TSN) talker/listener in a wireless communication system, the method including notifying, by the RAN, either an access and mobility management function (AMF) or a session management function (SMF) by using an NGAP message.
Abstract:
A method for processing a packet in a mobile communication network and a network element for performing the same. A first network element may receive a first data packet to be transmitted to a second network element via a third network element and add a header to the first data packet. The first network element may add time information associated with the first data packet to the header and transmit the first data packet with the header to the third network element.
Abstract:
A traffic distribution method through a multi-access network in a network and a network entity performing the same. A first device belonging to the network may trigger a change to an ATSSS (access traffic steering, switching, and splitting) rule corresponding to an established multi-access PDU session (MA PDU session) when the MA PDU session is established. A session management function (SMF) may transmit a first message including the changed ATSSS rule to an access and mobility management function (AMF).
Abstract:
A packet data unit (PDU) session release method and a network entity performing the same are disclosed.An access and mobility management function (AMF) may receive a PDU session release request message including an access type which is an access network to be released in a multi-access PDU (MA PDU) session from user equipment (UE) when the MA PDU session is established. The AMF transmits a first message including the access type to a session management function (SMF).
Abstract:
A packet data unit session establishment method and network entity performing the same is disclosed.User equipment (UE) may establish registration with the core network through a first access network when the UE is registered in a core network through a second access network belonging to the network and a first PDU session is established through the second access network.The UE may transmit a non-access stratum (NAS) message including a PDU session identifier (ID) that is the same as an ID of the first PDU session to an access and mobility management function (AMF).
Abstract:
Disclosed is a method of providing a video contents service including calculating conversion information indicating a relation between a projection area and an area corresponding to the projection area in order to project video contents on the area corresponding to the projection area which is a partial area within a prepared image in a user image photographed by a user terminal; and transmitting the calculated conversion information to the user terminal.
