摘要

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。
Multicast broadcast service (MBS) plays a key role in the emergency communication. UP-MBS and MP-MBS are the communication models in emergency communication,but there exist some shortages. In this paper two more reliable running styles,R-UP-MBS and R-MP-MBS,are designed through introducing ARQ mechanism in order to improve communication quality and reliability. Their running modes are discussed.
