This paper discusses the technique of corba based intelligent network service creation , proposes the architecture of the distributed corba based in , and presents the system design of corba based in services using gsl ( global service logic ) table , sib ( service independent building ) table , and edp ( event detection point ) table 本文研究了基于corba的智能网业务生成技术，提出了基于corba的分布式智能网体系结构。同时本文给出了corba平台上智能网业务的系统设计，即提出利用gsl （全局业务逻辑）表、 sib （业务独立构件）表和edp （事件检测点）表等来实现业务逻辑。
However , in the current mobile communications market , high tariffs and inconvenient applications often keep users from using mobile services . to overcome these disadvantages , local mobile companies nationwide will soon roll out virtual private mobile network ( vpmn ) service according to the centralized plan of their common group company . 2 然而，在目前的移动通信市场中，过高的电信资费和不方便的应用往往使得用户望而却步，为了消除这个门槛，各地移动通信公司在集团公司的统一部署下，即将在全国范围内提出虚拟专用移动网业务。
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 本文首先通过对传统智能网和综合智能网的原理、结构和标准等的比较分析,研究了实现固定智能网和移动智能网之间互联互通的必要性和可行性,提出了实现各传统智能网之间互联互通需要解决的问题;然后,通过分析综合智能网的体系结构、技术特点说明了实现pstn网、 gsm网和cdma网业务互通的过程;接着对本设计所采用的业务开发平台进行了介绍,详细说明了3g综合虚拟专用网业务的设计开发过程;最后,给出了一个基于camel的3g综合虚拟专用网业务的实现方案。
Vpmn service is a service which allows group users to communicate with each other through abbreviated numbering or dedicated numbering plans over a private network of logic voice circuits , based on the public land mobile network ( plmn ) and the public fixed telephone network ( pstn ) 虚拟专用移动网业务（以下简称为vpmn ）是在公用陆地移动通信网（ plmn ）和公用固定电话网（ pstn ）上建立一个逻辑话路专用网，通过缩位拨号、专用编号计划等方式使企业、集团用户群内进行相互联系的网络。
Taking into consideration of the competitive environment china telecom now faces , this paper analyses the existing problems and the situation now prevailing in china telecom and puts forward the method of computing guangdong telecom local network cost by finding out network basic unit cost driving factors and proposals for establishing a cost accounting system in telecommunication services 本文通过分析目前中国电信面临的竞争环境、中国电信在成本核算方面存在的问题和现状，提出广东电信本地网业务成本的测算办法，主要针对如何确定网络基本单元这个业务成本驱动因子，对目前的会计科目重新设计，提出建立电信业务成本核算体系的一些思路。
So using cti technology to study the in service carrying out in cti platform , it has perfect research foreground . this thesis chapter as follow : the first chapter describes the applications of cti and in ; the second chapter introduces the cti platform system , csta call handling protocol and tapi interface protocol ; the third chapter introduces in system and in " s call handling ; the fourth chapter construct a cti platform which applied the csta to actualize in " s call handling ; the fifth chapter introduces the actualize of csta , database , tapi call handling and gatewaya thought a example : a in service carrying out in the cti platform 本文安排如下：第一章介绍了cti技术和智能网的应用范围，以及本课题的研究内容；第二章介绍了cti平台的体系结构、 csta呼叫处理协议及接口协议tapi ；第三章介绍了智能网体系结构和智能网业务的呼叫处理流程；第四章是根据智能网业务的业务处理流程，构建了实现智能网业务的cti平台；第五章以一个业务为例，重点介绍了csta流程、数据库、 tapi呼叫控制和业务网关等功能的实现，并提供了部分源程序。
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 综合智能网是在传统智能网的基础上引入综合业务控制点( iscp )和综合业务管理点( ismp )发展起来的,同时支持pstn 、 gsm和cdma等网络的协议,解决传统智能网由于各网络相互独立、业务之间互不关联,给三网之间的互联互通带来的困难,实现三网业务的互通互享。
However , existing open system technology cannot support applications with some important performance requirements , such as mobility , which may be used to improve collaboration or to develop high efficiency mobile network business . but recently , the coverage of mobility application is greatly increased 但是，当前的开放系统技术更多关注的是功能方面的问题（如可互操作性、可移植性等） ，而对于有些重要的性能方面的问题，如移动性的保证（可利用其来提高合作性，或利用其来优化移动网业务)等，尚未涉及。
