Abstract


With the TD-SCDMA test coming to an end , and the restructuring of the domestic telecom operators for outgoing messages , 3G license issuance and commercial network has been put on the agenda of the formation , WCDMA, CDMA2000, TD-SCDMA standard three international mainstream choose to become a the operators key consideration . As for the different standards , 3G should be how to develop the underlying technology is the current communications equipment manufacturers face a problem as well as scientific weaknesses . Based on this, a communications equipment company proposed and designed compatible with major 3G standards underlying unified platform . 3G 3G network platform is the core technology platform and 3G system operators based on the technical architecture , and real-time detection (RSMM) is a platform for system control subsystem (SCS) core technology module, control and management platform . With the development of 3G commercial network , 3G platforms and RSMM of great significance. Based on the study on the basis of 3G platform , combined with mobile communications , networking and real-time operating systems such as hierarchical knowledge of embedded software development approach to design and implement a real-time detection module , and applied to the clock synchronization field , to design the platform clock systems . The main work of this paper are: First, design a real-time detection module , the application of active polling cycle timer interrupt and exception reporting a combination of detection methods , greatly improving the system detects real-time and accuracy , the realization of the whole system rapid and accurate detection and effective control . These technologies to achieve the detection of control theory has a certain reference. Then apply RSMM design framework , with the clock device and its drive control is designed by combining a highly integrated clock synchronization system , which uses a manually selected benchmark clock extraction circuit and a series of new technologies, and made a clock board preheating concept . It is the system control and real-time status detection module Typical application and implementation , also verified RSMM design is reasonable. In a three standards -compliant platform , designed and developed a real- time detection module with good performance and highly accurate clock synchronization system is the main results of this paper , but also on the underlying device 3G technological innovation and the development of control theory for the detection of a useful exploration . This thesis underlying technology has been in a domestic telecom equipment manufacturers to achieve large-scale commercial and running well.
