Enhanced Channel Switching in MBMS UMTS using a Dynamic Power Counting scheme

Abstract

In this thesis we propose a novel power based algorithm for switching between ptp and ptm in order to deliver MBMS content with minimum power consumption. Currently tra-ditional technique of UE counting uses only a predefined number of UEs participating in a multicast session to determine when to switch from ptp to ptm and vice versa. We in-vestigate the behaviour of both algorithms in several simulation scenarios with different parameters and finally we determine which are the advantages of the proposed algo-rithm compared to the UE counting algorithm.
