3 . The operation method of claim 2 , wherein the UEID represents a user or the user terminal by using a network access identifier (NAI), an international mobile subscriber identity (IMSI), a mobile station integrated system digital network (MSISDN), a subscription permanent identifier (SUPI), a generic public subscription identifier (GPSI), an international mobile equipment identity (IMEI), and a permanent equipment identifier (PEI).

4 . The operation method of claim 1 , wherein the subscription request message is a session establishment request message, a session modification request message, or a session release request message.

5 . The operation method of claim 1 , wherein the subscription response message is a session establishment response message, a session modification response message, or a session release response message.

6 . The operation method of claim 1 , wherein the subscription request message or the subscription response message or both further include at least one selected from a group of a subscription identifier (subId), a notification correlation identifier (notifId), a notification uniform resource locator (notifUri), event subscription information (eventSubs), a Quality of Service (QoS) flow identifier (Qfi), a Data Network Name (dnn), Single Network Slice Selection Assistance Information (snssai), Application id, a Packet filter, or Expiry.

7 . An operation method of a user plane function (UPF) in a wireless communication system, the operation method comprising:

providing a network function (NF) with a notification message including a second identifier, a notification correlation identifier (NotifId), and a notification event (event); and

obtaining, from the NF, a notification response message corresponding to the notification message, the notification response message including a first identifier,

wherein the first identifier includes a user plane session identifier (upSeId) assigned by the UPF, or a user session identifier that is a session identifier for a user termina, or both, and

wherein the second identifier includes a control plane session identifier (cpSeId) assigned by a session management function (SMF), or the user session identifier or both, and

wherein the eventSubs includes at least one event related to measurement data generated by the UPF, wherein the measurement data is related to a performance of user traffic and a usage measurement.

8 . The operation method of claim 7 , wherein the notification message further includes at least one selected from a group of a notification correlation identifier (NotifId), a notification event, a Timestamp, a timeDuration, an access type (accType), an identifier of the user terminal (UEID), a protocol data unit session identifier (pduSeId), a user plane session identifier (upSeId), a Quality of Service (QoS) flow identifier (Qfi), Data Network Name (dnn), Single Network Slice Selection Assistance Information (snssai), Application id, a Packet filter, 5G QoS Indicator (5qi), Delays, Jitters, or a Usage report.

9 . The operation method of claim 7 , wherein the user session identifier includes at least one selected from a group of an identifier (UEID) of the user terminal, a session identifier (PduSessionID) assigned by the user terminal, a Media Access Control (MAC) address, an Internet Protocol version 4 (IPv4) address, or an Internet Protocol version 6 (IPv6) address.

10 . The operation method of claim 9 , wherein the UEID represents a user or the user terminal by using a network access identifier (NAI), an international mobile subscriber identity (IMSI), a mobile station integrated system digital network (MSISDN), a subscription permanent identifier (SUPI), a generic public subscription identifier (GPSI), an international mobile equipment identity (IMEI), and a permanent equipment identifier (PEI).

11 . An apparatus for a user plane function (UPF) in a wireless communication system, the apparatus comprising:

a transceiver; and

at least one controller operably connected to the transceiver,

wherein the at least one controller is configured to:

obtain a subscription request message from a network function (NF), the subscription request message including a first identifier, notification uniform resource locator (URI) information (notifUri), and event subscription information (eventSubs), and

provide the NF with a subscription response message corresponding to the subscription request message, the subscription response message including a second identifier,

wherein the first identifier includes a user plane session identifier (upSeId) assigned by the UPF, or a user session identifier that is a session identifier for a user terminal, or both,

wherein the second identifier includes a control plane session identifier (cpSeId) assigned by a session management function (SMF), or the user session identifier or both, and

wherein the eventSubs includes at least one event related to measurement data generated by the UPF, wherein the measurement data is related to a performance of user traffic and a usage measurement.

12 . The apparatus of claim 11 , wherein the user session identifier includes at least one selected from a group of an identifier (UEID) of the user terminal, a session identifier (PduSessionID) assigned by the user terminal, a Media Access Control (MAC) address, an Internet Protocol version 4 (IPv4) address, or an Internet Protocol version 6 (IPv6) address.

13 . The apparatus of claim 12 , wherein the UEID represents a user or the user terminal by using a network access identifier (NAI), an international mobile subscriber identity (IMSI), a mobile station integrated system digital network (MSISDN), a subscription permanent identifier (SUPI), a generic public subscription identifier (GPSI), an international mobile equipment identity (IMEI), and a permanent equipment identifier (PEI).
