Research On Management Method Of Great Capacity Call For Short Message Admin Network Analysis System

As a result of the fast increment of SMS(Short Message Service), quantities of call produced in SMSC(Short Message Service Center) increase rapidly. At the same time, stability of Short Message Admin Network Analysis System have direct relationship with the interest of consumers. To improve the ability of monitoring and management for Short Message System, China Mobile decides to develop a set of Integrated Short Message Admin Network Analysis System based on existing data interface in Xin Jiang Province. The system can watch SMS platform, and provide potent data statistic and report forms. Great capacity of call data produced in SMSC is the source of statistic and report forms. So management of great capacity of call data is the key of design and implement of the system.Firstly, this thesis introduces main technique of implementing management of great capacity of call data, including FTP(File Transfer Protocol),database transaction processing, the rules of encoding and decoding, JDBC(Java Database Connectivity) and Oracle index technology.Then, the thesis analyses the requirement of the system, such as range of the system, the management object, goal of the system and function requirement. According to system requirement, the thesis describes design in detail and implements ways of great capacity of call management. Concretely, the thesis introduces flows of great capacity call management, such as downloading, parsing, storing and collecting call files in batches. At the same time, it introduces some key algorithms. Change of call file status presents in call file information table by Finite State Machines mechanism. Call file information table is received from SMSC and timing downloading call files in batches is implemented, via FTP. Accord to the type of call, the function of parsing short message content is implemented with 7-bit or UCS(Unicode Character Set) rules. The function of Storing and collecting call data is implemented with JDBC. The short message call data of MO/MT(mobile origination/mobile termination) is stored to the table SMSC HDMOMT and call data of MR is stored to the table SMSC_HDMR. According to the type of call, the sum of every record is stored to the sum table. Integrating of call parsing, storing and collecting is implemented, via database transaction in the call processing.Lastly, the thesis introduces test method of the system and educes a conclusion according to test data. The conclusion is that the system accord with the requirement, downloading call files in batches can be implemented , and call can be parsed correctly and be stored.
