Patent ID: 8260277

Claim:
A method to control a configuration containing an array of two or more telecommunication end devices (multiple-device configuration) in a public telecommunication network, characterized in that upon the activation by a subscriber of changes in the features of the public telecommunications network assigned to a first end device or to an identification chip connected to the first end device, these changes in the features are automatically activated, at the same time or with a temporal delay, also in the other end devices or in the identification chips connected to the other end devices of the multiple-device configuration, wherein an intelligent call control polls a mobility/profile database for the profile of the first end device or of an identification chip connected to the first end device and, at least partially, uses the profile to control the features during the call setup to at least one more end device; and including, before a call is delivered, polling the corresponding mobility/profile databases and switching facilities in which the end devices are located, the intelligent call control determining system status of an end device to be called, and immediately initiating a call forwarding process in accordance with the determined system status of the end device to be called and the activated feature of the end device to be called without setting up a line to the end device to be called; wherein if the determined system status of the end device to be called is free to receive a call, first the call is delivered in such a manner that should the call not be accepted, a corresponding line is released up to an origin of connection and, depending on the status of the end device to be called determined from the unsuccessful call attempt and previously determined settings of the end device to be called for call forwarding functionality, a direct connection is established to a desired call forwarding target.
