Abstract
The purpose is to prevent SIM spoofing within the mobile user plane. The method includes generating a Border Gateway Protocol (BGP) flow specification based on a range of Internet Protocol (IP) addresses associated with a route for one or more user devices. The method includes verifying the encapsulation of an internal IP packet based on the BGP flow specification in response to receiving a packet from a node in the radio access network.
