Trusted policy and charging enforcement function

摘要

A system for policy and charging enforcement function on a mobile access terminal. The system comprises a radio transceiver, a processor, a memory, and an application stored in the memory. The application stored in the memory, when executed by the processor, receives policy and charging rules via the radio transceiver, and enforces the policy and charging rules when the mobile access terminal initiates a wireless communication.

主权项

1. A method of trusted policy and charging enforcement function on a mobile communication device, comprising:
establishing a wireless communication link between a mobile communication device and a policy server; coupling a trusted security zone in the mobile communication device with a trusted security zone in the policy server; transmitting a credential from a policy and charging enforcement function application residing in the trusted security zone on the mobile communication device to a policy and charging rules function application residing in the trusted security zone on the policy server, wherein the credential is used to establish trust between the mobile communication device and the policy server for accessing the functionality of the mobile communication device; transmitting policy rules from the policy and charging rules function application on the policy server to the policy and charging enforcement function application on the mobile communication device; enforcing the received policy rules by the policy and charging enforcement function application on the mobile communication device; monitoring wireless network activities by the policy and charging enforcement function application on the mobile communication device; and transmitting, by the policy and charging enforcement function application on the mobile communication device, the monitored network activities to the policy and charging rules function application on the policy server.
