Optimisation of use of network resources of a public telecommunication network

摘要

The method involves activating service characteristics associated with a first terminal (B10) and/or an identification chip (Chip1) connected to the first terminal in such a way that changes in the service characteristics are effective simultaneously or with a time delay at further terminals (B20,B30) of the multi-device configuration and/or the identification chips (Chip2,Chip3) associated with the further terminals. Independent claims are also included for the following: (A) a system for optimized call delivery control (B) and a method of optimizing the use of network resources (C) and a system for optimized call delivery control for call diversion.
