摘要

1x EV-DO (1x evolution data optimized) broadcast-multicast service (BCMCS) enables a host of new applications in the mobility environment. Examples of such applications range from mobile TV broadcasting for the consumer market to supporting conference and "walkie-talkie" group calls for business, government, and public safety users. In this paper, we investigate aspects of BCMCS deployment and performance associated with the support of different applications. Through analysis and simulation, we evaluate BCMCS coverage and capacity in mobile TV broadcast deployment when using various transmission format configurations, such as soft handoff combining, orthogonal frequency division multiplexing (OFDM), and Reed-Solomon coding. We further propose a scheme for maximizing system-wide air interface resource efficiency when BCMCS is used to support wireless group calls. Using a Voice over Internet Protocol (VoIP) group call as an example, we show how the decision strategy for choosing BCMCS vs. unicast could be optimized on the basis of the group size, the geographical distribution of group members, and their mobility.
