接续网络的可靠组播在应急通信中的应用设计

组播业务在应急通信中的起着重要的作用。UP-MBS和MP-MBS是紧急情况下组播的通信 模式，但是该模式存在一定的缺陷。从提高通信质量和可靠性的角度出发，对这两种模式引 入了自动请求重传(ARQ)机制，设计了两种更为可靠的运行模式：R-UP-MBS和R-MP-MBS， 并详细阐述了它们的运行方式。

Reliable Multicast Application Design of Relay Network in Emergency Communication

Multicast broadcast service (MBS) plays a key role in the emergency com munication. UP-MBS and MP-MBS are the communication models in emergency commun ication,but there exist some shortages. In this paper two more reliabl e running styles,R-UP-MBS and R-MP-MBS,are designed through introducing ARQ mech anism in order to improve communication quality and reliability. Their running m odes are discussed.
