Title:
SOURCE BASE STATION, UE, METHOD IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/145005
Kind Code:
A1
Abstract:
"Prevention of user equipment from attaching to false base station in wireless communication network" Accordingly, embodiments herein disclose a method and base station for preventing a User Equipment (UE) from attaching to a false base station. The method includes: generating, by a source base station, a UE specific Anonymity Challenge Parameter to the UE based on sensitive information from the UE, cell information, source base station information and initial Anonymity Challenge Parameter assigned to the particular base station; and sending, by the source base station, a measurement command message including the UE specific Anonymity Challenge Parameter to the UE. Further, the method includes receiving, by the source base station, an Anonymity Challenge Parameter acknowledgement as a response from the UE; and negotiating, by the source base station, the UE specific Anonymity Challenge Parameter with the UE to prevent the UE from attaching to the false base station.
