Abstract

A telecommunications system includes a telecommunications switching system, at least one subscriber terminal coupled to the switching system, at least one telecommunications agency coupled to the switching system. The agency stores subscriber information and provides the information to external requestors in the form of subscriber service images defining services and features to be provided for subscribers. The subscriber terminal includes a portable subscriber module identifying the subscriber and optionally contains information defining services and features to be provided for the subscriber by the subscriber terminal and the switching system. The switching system has a facility for storing all subscriber-related information as a plurality of transient subscriber service images defining the services and features to be provided for subscribers having pending or active calls. When the subscriber requests service, the agency or the portable subscriber module provide the image information to the switching system, which creates an image instance and provides the requested service. Once the service is concluded, the image instance is released.
