Abstract: A server according to an embodiment can collect mobility data of user terminals and group the user terminals into clusters based on the similarity the similarity of the mobility data. The server applies identification information of the clusters to which the grouped user terminals belong and previous movement paths of the grouped user terminals to a neural network-based prediction model, thus making it possible to train a prediction model to predict a base station serving moving locations of the user terminals belonging to each cluster.

Abstract: 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.

Abstract: In various embodiments, a method performed by a mobility management device, includes obtaining mobility information of a user equipment (UE). The method includes generating a predicted tracking area list for the UE based on the mobility information. The method includes transmitting, to the UE, a message including the predicted tracking area list to initiate a registration procedure based on the UE being out of a range of a plurality of tracking areas of the predicted tracking area list. The method includes based on identifying downlink data for the UE, performing a paging procedure in each of cells in the predicted tracking area list.
