Design And Implementation Of Alarm Subsystem Of CDMA Network Management System

With the rapid development of communications networks and communications business expansion, a BSC contains more and more BTS, from around 300 base stations, and to the current 600 or even more, with a capacity of almost Expand doubled, so that the BSC increase the number of alarms a lot. In actually, a fault may lead to a number of alarms, but most probably the source of the alarm is only one, so that alarm data required us to determine accurate and detailed analysis, to identify this large number of alarms among the most important. If we don't make a comprehensive analysis and treatment, but only at the surface from a single alarm, it will increase in the difficulty of solving practical problems, the essential causes of the problem can not be found out and also have a bad influence about the services.Alarm subsystem of CDMA Network used in embedded development technology, operating systems, real-time performance is very good VxWorks, the background used in the main development language is C / C + +. This paper first describes the system development relies on integrated development environment tornado, and then describes the CDMA wireless communications field and the key technologies, and development embedded VxWorks operating system, made a detailed introduction. In accordance with software engineering way of thinking, first analysis of the needs of alarm subsystems, and then from the detailed structure of the subsystem design and functional design. This focuses on explaining the general alarm and alarm restore the principles and mechanisms, through the general alarm and recovery mechanisms for the analysis and discussion, leads in the traditional sense of alarm and recovery mechanisms for deficiencies.In the above analysis of association rule-based model of alarms related to the design and implementation of the alarm correlation, and finally through the software testing program to prove the feasibility of treatment correlation alarm. Warning so as to arrive at a deal with the relevance of the traditional sense of the general alarm and restore a great supplement to be able to effectively improve the positioning of our time and efficiency, not only at the level of surface reduction on the number of alarms, but also from the source of alarm to the alarm on the card correctly.
