Abstract
An operation method of a session management function (SMF) is provided. The method includes the steps of transmitting a request message to a user plane function (UPF) on the basis of the UPF and a session configuration, receiving a response message from the UPF, determining whether there is a lost usage amount on the basis of the response message, and, when there is a lost usage amount, transmitting recovered usage amount information to an online charging system (OCS), wherein the response message may include current usage amount information and cumulative usage amount information of the UPF.
Claims14
A method of operating a session management function (SMF), the method comprising:
- transmitting, based on a user plane function (UPF) and session establishment, a request message to the UPF;
- receiving a response message from the UPF;
- determining, based on the response message, whether there is a lost usage amount;
- and
- transmitting recovered usage amount information to an online charging system (OCS) in case that there is the lost usage amount,
- wherein the response message comprises current usage amount information and cumulative usage amount information of the UPF.
A session management function (SMF) device comprising:
- a transceiver;
- and
- at least one processor operably connected to the transceiver,
- wherein the at least one processor is configured to:
- transmit, based on a user plane function (UPF) and session establishment,
- a request message to the UPF,
- receive a response message from the UPF,
- determine, based on the response message, whether there is a lost usage amount, and
- transmit recovered usage amount information to an online charging system (OCS) in case that there is the lost usage amount, and
- wherein the response message comprises current usage amount information and cumulative usage amount information of the UPF.
A method of operating a user plane function (UPF), the method comprising:
- receiving, based on a session management function (SMF) and session establishment, a request message from the SMF;
- and
- transmitting a response message to the SMF in response to the receiving of the request message,
- wherein the response message comprises current usage amount information and cumulative usage amount information of the UPF, and
- wherein the cumulative usage amount information is information corresponding to a total amount of traffic used by the UPF since the session establishment.
A user plane function (UPF) device comprising:
- a transceiver;
- and
- at least one processor operably connected to the transceiver,
- wherein the at least one processor is configured to:
- receive, based on a session management function (SMF) and session establishment, a request message from the SMF, and
- transmit a response message to the SMF in response to the receiving of the request message,
- wherein the response message comprises current usage amount information and cumulative usage amount information of the UPF, and
- wherein the cumulative usage amount information is information corresponding to a total amount of traffic used by the UPF since the session establishment.
