An unlicensed spectrum usage monitoring and reporting method is disclosed. The unlicensed spectrum usage monitoring and reporting method employs a new logical entity in a Long Term Evolution (LTE) enhanced Node B (eNB) as well as a dedicated interface between the eNB and the Policy and Charging Enforcement Function (PCEF). The method employs a diameter-based protocol for communication between the eNB and the PCEF, and defines several new Attribute-Pair Values (AVPs) and message commands to enable exchange of unlicensed spectrum usage information for User Equipment (UE) operating in the LTE network.
