Patent ID: 8005963

Claim:
A method for preventing counterfeiting of a network-side media access control (MAC) address, comprising: receiving a message from a user equipment (UE), and parsing the message of the UE to obtain a MAC address of the UE; learning the MAC address of the UE if the MAC address of the UE is different from a known MAC address of a network-side equipment stored in a storage unit; learning a MAC address of the network-side equipment when the MAC address of the UE is different from the known MAC address of the network-side equipment stored in the storage unit; generating a MAC address learning table by utilizing the learned MAC address of the network-side equipment and setting the MAC address learning table to be a static address table, and filtering messages transmitted by the UE by utilizing the learned MAC address of the network-side equipment, the filtered messages having source MAC addresses identical with the MAC address of the network-side equipment and transmitted from other user-side ports.
