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.

Abstract: A user plane entity of a wireless communication system including the user plane entity and a control plane entity according to an embodiment may comprise: a at least one processor, comprising processing circuitry, individually and/or collectively, is configured to: detect whether a session message, which has been transmitted to the control plane entity by the user plane entity, for the volume quota allocation of a resource of the user plane entity is lost; generate a session message, including an arbitrary usage report, based on the session message being detected as being lost; and a communication interface, comprising communication circuitry, is configured to transmit the session message including the usage report to the control plane entity to attempt volume quota allocation.
