EXTENDED TELECOMMUNICATION SYSTEM ARCHITECTURE FOR OPEN SERVICE ACCESS

摘要

A telecommunication system providing extended open service access to multiple heterogeneous networks, hereafter called underlying networks, the system comprising: one unique common framework for the underlying networks; and a common service capability feature for the underlying networks providing a common network interface, wherein the common service capability feature comprising: a mapping means for mapping open service access interface classed to interfaces of the underlying networks; and a dispatcher means dispatching a request from an application to a corresponding network interface class so that the telecommunications system can simultaneously provide extended open service access to each underlying network; a terminal ID administrator for selecting a network service capability feature instance for an application based on terminal ID, said service capability feature instance being selected from a set of multiple service capability feature instances; wherein the terminal ID administrator comprises a database/directory containing mapping information between applications and terminal IDs.
