Research on functional requirements for Radio Block Center in CTCS-3

This paper focused on the functional requirements and external interface of Radio Block Center(RBC) in CTCS3.Through a deep analysis of requirements for CTCS-3,this paper obtained the main functions of RBC.The practical application in the CTCS-3 simulation platform showed that RBC functional requirements,information flow and external interface described in this paper could meet the need of CTCS-3 simulation and testing platform construction.
