ANALYSIS AND IMPROVEMENT OF SDF OF INTELLIGENT NETWORK
Wang Chun · Journal of Beijing Technology and Business University · 2007
Generally speaking,the two function entities in SCP(Service Control Point) of intelligent network,namely SDF and SCF are located in one process.Data operation,service logic execution and message processing are carried out in sequence.There is an inevitable problem in this architecture.Abnormal obstruction of data operation will make SCF obstructed,and then causes some serious consequences such as large call accumulation etc.To solve the above problems,it presents a solution that separates SDF from SCF in physical sense,so SCF operates data through SDF in an asynchronous mode.At the last,the performance optimization is considered.
