Research And Optimization Of Cdma Mobile Intelligengt Network Theory And Call Flow Message

With the development of mobile communication techniques and increasing requirement from the ISP and customers, the communication network must be intelligent and individual network in a point view of communication technique development. CDMA is the second generation mobile technique; in this technique, the network system structure is becoming more intelligent comparing with the traditional mobile network; the concept of intelligent network is introduced into the mobile network; the function modules are also integrated into intelligent network, which make it very easy to provide more new service to satisfy the customers' increasing and varying requirements.In this thesis, we introduced the principle, organization and functions of CDMA wireless intelligent network in the first part; and then the external , internal signal procedure and SDL procedure in PrePaid Charge service were also introduced and analyzed in detail.In the last part., we proposed our approach to optimize the PPC's message flow, which reduced the connection time and increased the connection rate.
