Abstract
A method for performing a location and velocity check at an SEPP to protect against a spoofing attack includes receiving an SBI request message relating to authentication of UE. The method further includes querying a database NF to obtain previous authentication information for the UE, the previous authentication information including a previous network identifier and a previous authentication time for the UE. The method further includes receiving a response from the database NF, the response including the previous network identifier and the previous authentication time. The method further includes reading, a current network identifier from the SBI request message, performing, using the current network identifier from the SBI request message, the previous network identifier, the previous authentication time, and a time of receipt by the SEPP of the SBI request message, a location and velocity check for the UE, and performing a network security action for the SBI request message based on results of the location and velocity check.
