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.

Device and method for recovering lost information in wireless communication system

An electronic device for a session management function (SMF) may comprise memory storing instructions and at least one processor. The instructions may cause the electronic device to: obtain a first load value for a second time interval before selecting a serving user plane function (UPF), estimated based on an artificial intelligence model (AI model) using first load information of each of UPFs measured within a first time interval before the second time interval, obtain a second load value for the second time interval, calculated by using second load information of each of the UPFs measured within the second time interval, determine a difference between the first load value and the second load value, and determine, using the difference, whether to use a predicted load value of each of the UPFs obtained based on the AI model to select the serving UPF from among the UPFs.
