【摘要】 近年来通信网络的不断快速发展带来了更加丰富多彩的业务需求。然而传统智能网技术的缺陷决定了它无法快速高效的提供新业务,下一代智能网必须朝着开放性、分布性、综合性的目标发展,其实现关键技术之一是以Parlay API为代表的开放式API技术。WCDMA网络朝着下一代网络的目标演进,其业务的实现理念为虚拟归属环境,他保证用户无论在何处,采用何种终端,都可以享受大量的个人化业务应用。因此,Parlay、ETSI与3GPP合作订制基于Parlay API的开放式业务架构标准用以实现虚拟归属环境。根据这些发展情况,本文提出了WCDMA网络中的业务提供的三种主要方式,分析各自的利弊。在WCDMA网络中业务的提供首先可以是在交换机上直接实现,呼叫控制短消息等基本业务都可以采用这种方式,若是采用这种方式提供补充业务则过于繁琐封闭。再者,为WCDMA制定的智能网CAMEL可用于实现大量的增值业务,为此网络中需添加CAMEL实体,交换机的软件也需要进行必要的修改升级。最后,本文提出基于Parlay API的开放式业务架构,应用此种方式可屏蔽低层通信协议,更方便快捷的提供新业务,同时也可以尽可能的重用现有CAMEL设备。本文重点描述了在MSC中直接实现基本短消息业务的方式,并总结当前业务的提供与实现,提出基于Parlay的下一代业务提供方式,在现有系统上的加以改进以提供灵活快捷的业务进行研究,并以具体的个性化业务举例说明。更多还原

【Abstract】 Recent years, the increasing rapid growth of the telecommunication networks brings more kinds of service demands. Thus easy creation and rapid deployment of innovative applications become challenges beyond the classical intelligent network technology. The next generation intelligent network must approaches to the goals of openness, distribution and integration. One of the key technologies is the open API represented by Parlay API technology.WCDMA network is developing to the next generation network. The virtual home environment (VHE) is the key service concept for the third generation network. It promises mobile user the ability of accessing a large range of personalized services, whatever the location or the terminal. So Parlay, ETSI and 3GPP cooperate with the open service access (OSA) based on Parlay API to realize the VHE.In light of these recent revolutions, this article proposes three possible scenarios for supporting service creation in WCDMA network and analyses their advantages and disadvantages. The first is providing basic services, such as call control and short message service, directly on the switching centers, but it is very fussy and obdurate to provide supplementary services using this method. The second is by deploying the CAMEL network to realize the value-added services. The CAMEL entities must be added in the network and some switching center software must be updated. Ultimately, this article outlines the OSA based on the Parlay API, then the lower communication protocols are screened, easy creation and rapid deployment of innovative applications become possible, and the existing CAMEL entities can also be reused.This article emphasis the provision of short message service on the MSC entity, and summarizes the service creation methods nowadays, outlines the next generation service creation method based on Parlay. Then describes how to deploy the Parlay API in the <WP=6>network to provide flexible and fast service creation, and give a material personal service for example.更多还原
