DVB-H - UMTS Integration at Radio Access Level

The provision of one-to-many multimedia services to mobile users over scarce wireless resources has to be performed in a cost-efficient way. In addition to various systems optimized for this type of service, such as DVB-H, UMTS was recently enhanced for support of multimedia broadcast and multicast services (MBMS) over the existing infrastructure. Since MBMS provision will reduce the UMTS capacity for its essential point-to-point services, the integration of UMTS and DVB-H may be beneficial. In this paper, we address the integration of DVB-H at the UMTS radio access level. We present an interworking architecture and discuss necessary modifications to UMTS.
