摘　　要：本文首先介绍了GSM预付费业务在欧洲推出和应用的情况、该业务的功能需求、类型和特点,最后较详细地讲述了通过设立预付费业务处理中心和智能网两种业务实现方案。文章认为,第一种方案对现有GSM网络影响较小,易于实现,但不能对用户帐目完全实行监控,功能单一,采用非标准协议,对其应用和发展产生限制。第二种方案虽然对现有网络影响大,但除预付费业务外,还能提供其它特定业务,且采用标准协议,能提供多供应商的运行环境。The prepaid GSM service in Europe is described in terms of roll-out and applications as well as functional requirements, service categories and attributes. The prepaid service can be implemented with either an addition of the Prepaid Service Handling Center in the GSM network or the IN technology. The first scheme has little impact on the existing networks and is simple to deploy, but it hinders the service applications and development due to its lack of complete control of user accounts, singleness of functionality, and the adoption of non-standard protocols. The second scheme, despite its great impact on the existing networks, provides additional services and multi-vendor operating environments, using standard protocols.
