WIRELESS COMMUNICATION CORE NETWORK AND METHOD FOR ANALYZING USER EQUIPMENT MOBILITY IN THE SAME

5G資安防護系統開發計畫

一種無線通訊核心網路與在其中分析用戶設備移動的方法被揭露。在無線通訊核心網路中，應用功能（AF）提出分析請求，以要求用戶設備的移動分析報告，且包含用戶設備的第一用戶設備移動資訊。根據該分析請求，網路資料分析功能（NWDAF）自行或透過網路開放功能（NEF），從統一數據管理（UDM）取得服務用戶設備的接入和移動管理功能（AMF）的識別。網路資料分析功能（NWDAF）根據該識別，從接入和移動管理功能（AMF）取得用戶設備的第二用戶設備移動資訊，且根據第一用戶設備移動資訊與第二用戶設備移動資訊，產生且傳送移動分析報告至應用功能。

A wireless communication core network and a method for analyzing mobility of user equipment in the same are disclosed.  In the wireless communication core network, an Application Function (AF) make an request for analytics report of UE mobility of a UE, which includes first UE mobility information of the UE.  In the wireless communication core network, a Network Data Analysis Function (NWDAF) obtains an identity of an Access and Mobility Management Function (AMF) serving the UE from a Unified Data Management (UDM), on its own or through a Network Exposure Function (NEF), based on the request.  Then, the NWDAF obtains second UE mobility information of the UE from the AMF according to the identity of the AMF, and generates and transmits the analytics report to the AF according to the first and second UE mobility information.
