The Design And Implementation Of Integrated Intelligent Network Services

Integrated Intelligent Network (IN) is developed by importing the Integrated Service Control Point (ISCP) and Integrated Service Manage Point (ISMP) based on the traditional Intelligent Network (IN). It supports several diffirent kinds of protocols at the same time, and connects with the Service Switch Point (SSP) of different telecommunication networks and provides service across PSTN, GSM, CDMA and data network. It solves the problem of the mutual communication of tri-networks.The necessity and feasibility of mutual communication between different traditional INs are expounded by analyzing and comparing the principle, construction and protocols of traditional immobile IN and Mobile IN in this paper. The key problems to be solved in the implementation of the mutual communication are put forward. Then, the procedure to realize mutual communication of PSTN, GSM and CDMA is introduced by analyzing the Integrated IN's architecture and technique characteristics. Then, the developing platform of the integrated IN is presented. The design of the application of 3G iVPN service is explained in detail as an implement of Integrated IN. Finally, an implement scheme of 3G iVPN service based on CAMEL (Customized Applications Mobile Enhanced Logic) is designed.
