Claim of US Patent No. 9,191,865

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 first LTE gateway system, exchanging first hardware trust data with a trusted server system to maintain hardware trust
for the first LTE gateway system;

in an LTE access node, processing a Radio Resource Control (RRC) message that contains a trusted bearer requirement for the
UE to generate an S1 Application Protocol (S1-AP) initial UE message that contains the trusted bearer requirement for the
UE;

in an LTE management node, processing the S1-AP initial UE message to generate a General Packet Radio Service Transfer Protocol
(GTP) create session message that contains the trusted bearer requirement for the UE; and

in the first LTE gateway system, exchanging user data for the UE between the LTE access node and a communication node responsive
to the GTP create session message.
