Design And Implementation Of Tianjin Unicom Exchange SMS Gateway

With the development of mobile communications, message access to the explosive growth of the business, the service mode of operators also shifted by an independent win-win cooperation and in this context the construction of the exchange SMS Gateway is very necessary and of great significance. The main thesis of this content through the project needs of Tianjin Unicom exchange SMS Gateway, standardize equipment and related technology research, design and realization of a set of exchange SMS Gateway system to meet the needs of system functionality and performance to ensure that Tianjin Unicom SMS Exchange of business development.This article first analyzes the "peer-to-peer short message exchange protocol between the Telecom Operators" and Tianjin Unicom gateway for message exchange functions, performance requirements. Through needs analysis, put forward the necessary focus on resolving the two major difficulties: First, how to ensure the system performance in the case of large volume of business? Second, how to ensure uninterrupted operation of the system? For these two difficult problems, put forward a Hot Standby and clustering of two technology options, through comparing the advantages and disadvantages of the two plans, programs finally identified clusters. Subsequently, a system's overall architecture design, hardware architecture design and software architecture design. Then, a major sub-system design and implementation, in the communications subsystem, for the SMPP protocol interface, the short message exchange protocol between network interfaces and message routing module design and implementation; at billing subsystem, a log processing, warehousing, status report on the design of matching module implementation; in the statistical analysis subsystem, focusing on description of database tables and stored procedures partition design; at management subsystem, briefly introduce the management interface of the functional design. To ensure that the system robustness, a wrong treatment design; In order to ensure the systems ease of use, operation and maintenance of a design; To ensure the safety of the system, and carried out the design of the security and confidentiality. At system design and development process, in order to maximize the use of system resources, improve the efficiency of treatment using the multi-process, multi-threaded, such as concurrent treatment technologies; in data processing, use of shared memory, message queues, databases, large table Zoning technology, in order to ensure the efficiency of data processing; In order to achieve continuous operation and high system scalability goals, using clustering and load balancing technology.Tianjin Unicom exchange SMS gateway in early November 2008 to complete the design development and factory testing, the same year, December 5 through the testing and acceptance of Tianjin Unicom, and running on the same day. The exchange SMS gateway operates normally, experienced a peak period test of Christmas Day, New Year's Day, and Chinese New Year. After the exchange SMS gateway running quality analysis, the system reached a peak flow of 1568 / s, while the average utilization rate of resources at below 65%. Run shows that after the on-line system in the function and performance to meet the project needs and design objectives. Through a period of operation and user feedback, the system in the ease of use, alarm monitoring methods and the safety of storage, an inadequate response to existing problems, and suggestions to improve the idea.
