多媒体消息业务（Multimedia Messaging Service-MMS）作为一种新的移动数据业务已经得到了大规模的应用，在移动智能网上也可以支持这种业务。ITU-T、ETSI 对移动智能网支持MMS 并无相应的规范，目前国内计划采用的是SCP（Service Control Point）与MMSC（Multimedia Messaging Service Center）互联的解决方案。本文在对此方案做详细分析的同时，提出了基于CAMEL（Customized Application for Mobile Enhanced Logic）的MMS 体系结构，并对此进行了深入的探讨。在此基础上，分析计算了智能多媒体消息业务对SCP 及信令链路造成的影响。

The current trend in the mobile telecommunication market is to provide variable valueadded data services over GPRS networks. The evolution from the GSM Intelligent Network (IN) system which has been widely deployed towards the GPRS IN system allows the operators to build new data services in a cost-effective, speedy way. In order to achieve this evolution smoothly and efficiently, it is necessary to consider the essential differences between the GSM IN and the GPRS IN which would do virtually effect on the system implementation. Those differences, together with the corresponding key technologies are discussed and analyzed in this paper. Some value-added services which are hopeful to be deployed firstly on the commercial GPRS IN system are proposed. It's believed that some enhancements to the architecture specified by the 3rd Generation Partnership Project (3GPP) could enrich the features and types of the GPRS IN service, which are also our further study topics.

因特网和智能网都是目前发展势头强劲，潜力巨大的技术，将两者有机结合起来将对网络和业务的发展起到积极的推动作用。文中列举了与IN/Internet互连相关的标准化组织及其研究计划，然后在讨论IETF和ITU-T提出的互连方案的基础之上提出北京邮电大学国家重点实验室的实现方案。

Referring to IN/Internet interworking models proposed by ITU-T (International Telecommunication Union-Telecommunication standardization sector) and IETF (the Internet Engineering Task Force) respectively, a new model is designed based on CMIN02 (China Mobile Intelligent Network version 02) system of BUPT (Beijing University of Posts and Telecommunications). This model carried out heavy modifications and refinements on the former two reference models. This model can be divided into three layers horizontally and three sections vertically. Because of the importance of gateways, emphases are put on them especially. Moreover, a novel notion called information flow trail is proposed, which is useful to design complex gateways. Most of previous works on gateways are devoted to studying simple cases where gateways have only two interfaces towards outside. On the contrary, MGF (Management Gateway Function), SCGF (Service Control Gateway Function) and C/BGF (Call/Bearer Gateway Function) have more than two interfaces and the novel notion is useful. During the implementation of the project 863 the modified model has been tested and proved viable.

In ATM networks, bursty sources can be described as the Interrupted Bernoulli Pro-cess(IBP). With the use of the thin process theory, the Probability Generating Function(PGF) of the IBP is obtained. An iterative algorithm, which can be used to calculate the IBP probability distribution, is presented. The bursty source's equivalent description is discussed. It is proposed that the leaky bucket output process can be approximately described as the IBP. The accuracy of the analytical results has been largely validated by means of the simulation approach. Moreover, how to improve its accuracy is discussed. The smoothing function of the leaky bucket algorithm is quantitatively analyzed.
