Design and implementation of dynamic charging plan for IMS-based multicast services

3GPP has standardized Multimedia Broadcast Multicast Service (MBMS) to deliver multimedia services with high bandwidth efficiency through IP multicasting technology. In this paper, we present the implementation details of an MBMS test-bed with the standardized Policy and Charging Control (PCC) to realize the dynamic charging plan for multicast services. Specifically, we illustrate the detailed message flow and the design block diagram with 3GPP policy and charging control. The corresponding performance metrics (e.g., signaling delays) have been measured through our test-bed.
