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.
Claims19
A method performed by a session management function (SMF) for providing a user plane function (UPF) event exposure service for user data monitoring in a wireless communication system, the method comprising:
- receiving a UPF event subscription request through a service based interface (SBI) from network data analysis function (NWDAF) including at least one of an event ID, an event filter information applied to an event, UPF data subscription information, or control information for directly transmitting an event result to the NWDAF through the SBI;
- regenerating the UPF event subscription message or service operation on a basis of the event ID, the event filter information, the UPF data subscription information, and the control information;
- and
- transmitting the regenerated UPF event subscription message or service operation through an N4 interface or an Nupf_EventExposure service interface to the UPF.
A session management function (SMF) for providing a user plane function (UPF) event exposure service for user data monitoring in a wireless communication system, the SMF comprising:
- a transceiver, and
- a control part operably connected to the transceiver,
- wherein the control part is configured to:
- receive a UPF event subscription request through a service based interface (SBI) from the network data analysis function (NWDAF) including at least one of an event ID, an event filter information applied to the event, UPF data subscription information, or control information for directly transmitting an event result to the NWDAF;
- regenerate the UPF event subscription message or service operation on a basis of the event ID, the event filter information, the UPF data subscription information, and the control information;
- and
- transmit the regenerated UPF event subscription message or service operation through an N4 interface or a Nupf_EventExposure service interface to the UPF.
A method performed by a user plane function (UPF) for providing an UPF event exposure service for user data monitoring in a wireless communication system, the method comprising:
- receiving an UPF event subscription message or service operation through an N4 interface or an Nupf_EventExposure service interface from a session management function (SMF), and
- transmitting directly the event result through a Nupf_EventExposure service interface to network data analysis function (NWDAF), when the event occurs,
- wherein the UPF event subscription message or service operation includes at least one of an event ID, an event filter information, UPF data subscription information, or control information for directly transmitting an event result to the NWDAF.
A user plane function (UPF) for providing an UPF event exposure service for user data monitoring in a wireless communication system, the UPF comprising:
- a transceiver;
- and
- a control part operably connected to the transceiver,
- wherein the control part is configured to:
- receive an UPF event subscription message or service operation through an N4 interface or a Nupf_EventExposure service interface from a session management function (SMF);
- and
- transmit directly the event result through a Nupf_EventExposure service interface to network data analysis function (NWDAF), when the event occurs,
- wherein the UPF event subscription message or service operation includes at least one of an event ID, event filter information, UPF data subscription information, or control information for directly transmitting an event result to the NWDAF.
