Telecommunication Softswitch Service Provisioning System

Telecommunication Operation Support System (OSS) involves the technology in the fields of computer software and communication. After many years of development in international and domestic, the telecommunication OSS has been enhanced into a phase of utility development from the phase of theory researching.The Telecommunication Softswitch Service Provisioning System (TSSPS), as a component of OSS, is a necessary and critical software system. The technology advantage of this innovative telecommunication network with the core of Softswitch has been fully displayed by applying the advanced operation support technology. The technology enhances the level of telecommunication operation while decreases the cost.This paper mostly discusses the designing and realizing of the TSSPS. Firstly,it proposes a global framework of TSSPS after analyzing the requirement character of Softswitch service provisioning and studying the function of TSSPS in TOM model. The specific requirement of Sichuan Unicom' s "Xinji Network" Softswitch provisioning system and the general requirement of Softswitch service provisioning system are all considered when designing this framework.Secondly, based on the feature of Softswitch' s open service architecture, the software implementation methods of managing the Softswitch provisioning process are proposed in this paper after analyzing the Softswitch service and the provisioning process. In the management of the user-end device configuration process, the way of accessing the Softswitch network by the user, user-end device and the configuration process of these devices have been researched, and the consolidated management of the installation process and configuration process of these devices has been implemented.In order to harmony the automatic configuring process with the manualprocess in the Softswitch provisioning and the user-end device configuring, the paper introduces the workflow management technology into the TSSPS, then analyzes and designes the workflow process definition of the service provisioning system, and also describes the implement of the workflow management.Finally, the CORBA distributed component technology is introduced in this paper, the TSSPS is designed and realized using the way of Component-Oriented Programming (COP). Wherein the details of the implementation process of the database access component are mainly described.
