A FRAMEWORK FOR UNLICENSED SPECTRUM USAGE MONITORING AND REPORTING IN LTE NETWORKS

摘要

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.
