1. A method of operating a Long Term Evolution (LTE) communication network to transfer data communications for User Equipment (UE), the method comprising:

  • in a hardware-trusted Packet Data Network Gateway (P-GW), exchanging hardware trust data with a trusted server system to maintain hardware trust for the hardware-trusted P-GW, wherein another P-GW does not maintain hardware trust with the trusted server system;

    in a Mobility Management Entity (MME), processing a first S1-AP initial UE message that contains a UE Identifier (ID) and a trusted bearer requirement for the UE and responsively transferring the UE ID and the trusted bearer requirement to a Home Subscriber System (HSS);

    in the HSS, processing the UE ID and the trusted bearer requirement to identify and transfer a hardware-trusted Access Point Name (APN) for the UE;

    in the MME, processing the hardware-trusted APN for the UE to select the hardware-trusted P-GW for the UE and responsively generating and transferring a first General Packet Radio Service Transfer Protocol (GTP) create session message for the UE; and

    in the hardware-trusted P-GW, exchanging first user data for the UE responsive to the GTP create session message.
