摘要
详细分析了基于移动网络增强型逻辑的客户化应用(CAMEL)规范的通用分组无线业务(GPRS)智能网,指出了其中因采用服务GPRS支持节点(SGSN)作为业务触发实体而导致的一些缺陷.在此基础上提出了一个完整的基于网关GPRS支持节点(GGSN)触发的GPRS智能网方案,包括功能结构、状态模型和消息流的描述.给出了新方案中实现GPRS智能业务的基本信令流程.
The general package radio service (GPRS) intelligent network based on customized applications for mobile network enhanced logic (CAMEL) specification is analyzed in detail. And some disadvantages that are caused by serving GPRS support node (SGSN) triggering are presented. Thereby, a whole GPRS intelligent network solution based on gateway GPRS support node (GGSN) triggering is proposed. The new solution contains the functional architecture, the state models and the information flows. The fundamental signaling flows of GPRS intelligent services in the new solution are illustrated finally.
