摘要

3GPP 23.246 proposed the Multimedia Broadcast Multicast Service (MBMS) to deliver multicasting content in the Universal Mobile Telecommunications System (UMTS). In MBMS, the common logical channel is enabled to serve multiple MBMS calls at the same time. Use of the common logical channel may cause interference to the dedicated logical channels serving the traditional calls. To more efficiently utilize the radio resource to serve both traditional and MBMS calls, this paper proposes two channel allocation algorithms: Reserved Resource for Multicasting (RRM) and Unreserved Resource for Multicasting (URM). We propose analytic models and conduct simulation experiments to investigate customer Satisfaction Indication (SI) for the two algorithms. Our study indicates that URM outperforms RRM in terms of customer SI.
