专利汇可以提供Fault detection system for slave station in slot aloha type communication system专利检索,专利查询,专利分析的服务。并且PURPOSE: To prevent system congestion by allowing a slave station to reply a command for detecting the fault of the slave station with the slot reservation system in the case of the command from the master station and avoiding the data collision with the reply from other slave station.
CONSTITUTION: A satellite access controller(SAC) 1 originates a fault detection command to a base band processor(BBP) 2 sequentially every prescribed time based on a timer in relation to a command outgoing routine for detecting the fault. In this case, the SAC 1 reserves a slot in the timing replied in advance with each BBP 2 at every slave station and describes its information into a fault detection command. The BBP 2 receiving a fault detection command from the master station uses slot reservation information in the command to reply the SAC 1 through a designated slot at every slave station.
