Abstract
Prevention of SIM spoofing in mobile user plane. A method includes establishing a session for a user equipment to communicate with a session management function (SMF) and a user plane function (UPF), and then snooping a message between the SMF and the UPF to acquire one or more of an address for the user equipment, a tunnel endpoint identifier, or an address for a node within a radio access network. The method includes generating a route for carrying the one or more of the address for the user equipment, the tunnel endpoint identifier, or the address for the node within the radio access network, and then providing the route to a router.
