A Policy and Charging Enforcement Function (PCEF) device of a network having a Policy and Charging Rules Function (PCRF) device. The PCEF device includes a processing unit that detects a tunneled packet and the packet's Internet Protocol version type and determines whether activation of PCC rules in accordance with the IP version type of the tunneled packet is required from the PCRF device. The PCEF device includes a network interface unit in communication with the processing unit and the network that requests from the PCRF device required activation of PCC rules and identifies the IP version type of the tunneled packet to the PCRF device with the request and receives from the PCRF device the PCC rules activation. The processing unit enforces the PCC rules on the tunneled packet. Methods of handling and enforcing rules at a PCEF device of a network and at a PCRF device are also disclosed.
