Abstract:

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.

Key words: customized applications for mobile network enhanced logic, general packet radio service, gateway general package radio service support node
