Comparison of mobile TV deployment strategies in 3G LTE networks

摘要

In this paper, we propose a cross-layer analytical model to assess the capacity of a cellular network offering both TV and unicast (voice, data) services. Different mobile TV deployment strategies are then studied. This includes unicast-based TV and two broadcast/multicast approaches based on 3GPP MBMS, namely, single cell point to multipoint (SC-PtM) and MBSFN (MBMS over single frenquency networks). We compare the different strategies from two points of view: 1. the quality of service (QoS) they insure for TV users and their impact on unicast services and 2. the trade off between the QoS needs of the different services is discussed and the best TV deployment strategy is given for different traffic scenarios.
