【摘要】 随着全球信息产业的发展,互联网与传统电信网的融合成为新的发展趋势。随着技术的不断发展,用户希望能够利用任何终端,在任何时候任何地方都可以享受到丰富多彩的业务的愿望越来越强烈。传统运营商面临着与互联网应用提供商的激烈竞争。因此传统电信运营商希望有一个能够整合的IP化的电信基础网络来支持多种电信业务,满足用户越来越多的需求。在这种市场的需求下,IMS(IP多媒体子系统)作为下一代网络控制技术的核心正引起业界的广泛关注。基于因特网协议(IP)的移动设备联网是新一代的通信理念这种新的通信理念远远超出了老式电话的能力,它可以基于目前的通用分组无线服务(GPRS)网络来实现。为了实现通信功能,基于IP的应用必须具有一种到达使用者的机制。目前的电话网络提供了建立连接的关键功能。通过呼叫B号码,网络可以为任意两个终端建立一个特定的连接。在因特网上,这一至关重要的IP连接能力只能相对隔离地在单个服务提供商内部提供,因此我们需要一个全球的系统──IMS,他使得移动设备应用之间可以建立对等连接。随着IMS网络的日益壮大,如何管理好和使用好网络内部的用户数据,快速的建立路由关系变得相当有意义。同时,目前传统电信网络已经非常成熟,如果让新兴的IMS网络能够分享传统电信网络的数据,这将对新技术的推广有着深远的推动作用。上提出的实用性强的方法对IMS用户数据进行管理。同时提出了一个简单的与传统电信网络通信的方法。并将这两个新的功能集成在一个系统中,给它取名为IPWorks。本次研究的过程中首先了解和分析在IMS领域如何标识用户身份方面的最新技术动态;通过公共用户身份和私人用户身份的概念来对用户进行识别,以便于工作的开展;采集IMS领域用户的所有可能的数据,进行分析,构造数据库表结构的构成;为了快速查询到用户的id,提出了查询用户id的优化算法──解密树;提出如何实现IMS与传统电信网络数据共享的雏型;最后设计了衡量系统性能的实验。更多还原

【Abstract】 With the information industry developing globally, the Internet merging to the traditional telecom network becomes a new developing trend. With the continuous progress of technology, there has been a growing interest among the customers in enjoying colorful services via any kinds of terminals anywhere at any time. The competition between the traditional operators and internet vendors is getting fiercer and fiercer. Hence, the traditional telecom operators hope there is an integrated telecom basic network with IP to support different kinds of telecom services to meet the ever growing requests from customers.Under this kind of market situation, IMS (IP Multi-media Subsystem), which is taking the role of the technical kernel to control the next generation of the network, attracts more and more eyes from the information industry. The mobile terminal network basing on IP is the new telecom concept. The new telecom concept, which far exceeds the capability of the old-fashioned telephones, and can be deployed above the GPRS.To ensure the telecom function, the application based on IP should be equipped with a mechanism to reach the end users. Currently, the telephone network has the ability to build the connection between users. Via calling B number, the network can set up any specific connection for any two terminals. In Internet, the essential IP connecting capability can only be realized in the isolated service vendor internally. So, we need a global system --- IMS which can setup the corresponding connections among the mobile terminal applications. With the improvement of IMS, it will be of profound meaning to explore an effective way to well manage the customer data and quickly track the routing information in the call setting up phase. Meanwhile, currently, the traditional telecom network is very mature. If the rising IMS network can take use of the data from the traditional telecom network, this will make this new technology more useful.In this paper, the paper will firstly discuss the regulation of user recognition used by IMS network currently. Then based on the present regulation, it will propose a new way with high practicability to manage IMS custom data. Moreover, this paper also examines a simple and feasible way is come up with to communicate with the traditional telecom network. The two new functions are integrated into one system, namely, IPWorks.更多还原
