Abstract: A method for routing service calls in a telecommunication network, in particular those associated with the intelligent network of a network operator (TP), with a switching center recognizing the service call and a control facility controlling the service call. The call coming from the subscriber (TN) is recognized as a service call and the control facility receives an information signal (IDP) via the switching center. If the control facility can neither resolve the service number down to a physical address, nor determine the network operator in whose network the service is provided, the switching center receives a message via the control facility, and forwards the service call to a further switching center via the switching center.

Abstract: The present invention concerns a Method for routing service calls, in particular those associated with the intelligent network of a network operator (TP), in a telecommunication network, with a switching centre (SSP′) recognising the service call and a control facility (SCP) controlling the service call, with the steps:

Abstract: The invention relates to a method of setting and performing freely programmable functions of a telecommunications terminal (U) with function control keys (KB) and a control unit (Ctrl) for initiating functions which are selected by actuating the function control keys, and with an access unit (UIC) providing access to the telecommunications network (N), wherein for the purpose of setting or performing a function, a connection is established between the control unit and a service unit (S1, S2) via the access unit, and wherein the setting or performance of the function takes place from this service unit, and to a telecommunications terminal.

Abstract: In known telecommunication systems a combination of a switch like a Service Switching Point or SSP and processor means like a Service Control Point or SCP can be used for providing several virtual private networks, which are completely independent. By allowing at least one destination of a virtual private number of one of said virtual private networks to correspond with a destination of a virtual private number of another virtual private network, the number of user possibilities is increased, like for example two companies each one of them having its own virtual private network and both having the possibility to work with the same secretary who works at home or with for example a secretary company situated at another location.
