| 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。 |

| Abstract: |
| 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. |
