1. A method of wireless communication enabled by hardware assisted trust, comprising:

  • receiving, by an enhanced node B, a trust zone set-up request from an electronic device attached to a long term evolution wireless network;

    forwarding the trust zone set-up request from the enhanced node B to a home subscription server while executing in a trust zone of the enhanced node B, wherein the trust zone provides hardware assisted trust and comprises a secure partition within a subsystem of the enhanced node B, wherein, responsive to the set-up request, the trust zone of the enhanced node B disables execution of components within the subsystem that are outside of the secure partition and the trust zone denies components, that are outside of the trust zone, access to resources in the secure partition;

    receiving, by an enhanced node B, a trust zone set-up confirmation from the home subscription server in response top the trust zone set-up request, and forwarding the trust zone set-up confirmation to the electronic device, wherein the receiving and forwarding of the trust zone setup-confirmation occur while executing in the trust zone of the enhanced node B;

    receiving, by an enhanced node B, a trusted service request from the electronic device after receiving the trust zone setup-confirmation;

    forwarding, by an enhanced node B, the trusted service request to a policy control rules function server while executing in the trust zone of the enhanced node B;

    receiving, by an enhanced node B, a trusted service request authorization from the policy control rules function server, and forwarding the trusted service request authorization to the electronic device, while executing in the trust zone of the enhanced node B; and

    providing a trusted bearer communication link to the electronic device via the enhanced node B in response to the trusted service request.
