【摘要】 随着语音技术的发展,语音网络正在进入一个全新的变革时代——下一代网络(NGN—Next Generation Network),NGN向用户提供了全新的通信模式。在因特网可通达的区域,在国家法律法规允许范围内用户可以免受地域限制地使用和经营通信业务。同时,下一代网络引入了虚拟运营的概念。因此在广域网、城域网的网络环境下,必须面向客户、经营业主、虚拟运营商提供集中、有效、安全的计费系统,使不同的用户可以得到各自权限以内的计费、话务情况等敏感信息。 本文介绍了一个应用活体指纹认证技术的NGN虚拟运营系统的设计与开发工作。该系统建立在网络数据库平台上,能够平稳解决第二代IP电话网络(VOIP—Voice Over IP)向NGN通信刚演进时所带来的计费问题,能够实现实时电话通信以及语音通信业务的计费,同时向各个层次的用户提供各自所属的敏感信息。为解决使用过程中带来的安全性问题,本系统应用了基于活体指纹识别技术的认证技术,完成了话单批价、出帐等计费流程,初步实现了综合营帐功能。作者将NGN计费系统分为四个子系统,先后开发了身份认证子系统、营业管理子系统、虚拟运营系统、公话营业子系统等四个子系统。本文一章介绍了本文选题的背景和意义,第二介绍了下一代网络的网络构架和相关主要协议,分析了传统运营支撑系统在进入NGN通信网时遇到的问题;第三章介绍了所设计的虚拟运营系统的网络架构、开发平台、关键指标更多还原

【Abstract】 With the development of voice technology, voice network has entered an absolutely new and reformative age-NGN(Next Generation Network). NGN communication network provides users an absolutely new communication module. With this technology, users can use and manage the communication businesses under legal permissions without the restriction of area as far as the Internet can reach. Furthermore, the conception of virtual communication provider was introduced into NGN communication network. Under the WAN (Wide Area Network) and MAN(Municipal Area Network) environment, an integrated, effective and secure charge system is indispensable for customers , business owners and virtual communication providers so that different users can acquire their own sensible information, such as service bill and voice traffic.This paper introduces the biometric technology in NGN charge system. The system is developed based on network databases. It can solve the problems of charge systems which arise while evolving from second-generation VoIP(Voice over Internet Protocols) network to NGN network. It can also provide charge ability for real-time telephone communication or voice communication services, as well as the sensible information for users of respective levels. Anauthentication mechanism is adapted to solve security problems, which is based on active ringer print distinguish technology, and can be used for bill pricing and accounting. It preliminarily realized the comprehensive business account function.The NGN charge system includes four essential parts of subsystems, the security management subsystem, the business management subsystem, the business account subsystem and the public telephone business subsystem. In this paper, the first chapter describe the the background and meaning of this thesis . The second chapter introduce the evolution of network, the NGN communication framework and the core protocols, and the problems of charge system in the evolution of network. The third chapter mainly introduces the net architecture of the system , the design platform and the application of fingerprint identification technique. In the forth chapter a NGN virtual operation system based on fingerprint identification is described . In the last chapter the system implementation is described.更多还原
