Method and application device for introducing services in a private communication system from a public communication network

For control of performance features in a communication network, in particular, private communication networks, is a coupling of the communication systems, in particular private branch exchanges, provided with an application device via an application interface or ACL interface. According to this application interface is physically the private communication system, for example, the private communication system HICOM 300 from Siemens, connected via a V.24 interface or alternatively via an ISDN basic rate interface (S0) to the application device. The application interface is preferably present in an administration and maintenance unit - the communication system HICOM 300 an integrated administration and maintenance server - a communication system implemented and controls the communication exchange according to a defined protocol - eg MSV1 - with defined messages. Embedded in the message information corresponding to the switching-oriented instructions and event messages of the communication system. As a link between the application device and the communication system a for execution of switching-oriented instructions and to generate the switching-oriented event messages appropriate, ie a DVA-controlled connections to supportive program structure is in this, said affected by the switching-oriented instructions call control and switching-oriented event messages of current switching condition of connections ie is also incoming calls displayed.

Furthermore, by connected to a private communication system communication terminals using the user interfaces of the respective communication terminals features such as call forwarding and call, can be activated. Usually, for example, a subscriber activates call forwarding to its associated communication terminal to at his communication terminal, incoming calls to another communication terminal, for example, to another communication terminal in his company to redirect. The callback feature enables a subscriber to after an unsuccessful call when connected to the private communication system communication terminal - automatically obtain from this a recall - ie an internal subscriber. In certain situations, for example, on business trips or at a home office, it would be advantageous of any communication terminals of a public communication system in a connected to this private communication system performance - for example, call forwarding or call - to set up or to enable or disable. For example, should be be set up and activated by a subscriber who is on a business trip, at its associated communication terminal in the private communication system, a call back to that in the public communication network arranged communication terminal to which the subscriber is currently located.

The the object underlying the invention is to provide a setting or activation of features of devices connected to a private communication system communication terminals of a public communications network, ie externally to allow from. The object is solved by the features of claim 1.

The essential aspect of the method is the fact that all of a communications network, in particular public communication system, a communication system - directed particularly private communication system, unsuccessful calls and at least one performance feature communication terminal of the private communication system directed calls are recorded. The inventive method is designed for incoming calls that are in the communication system by means of inserted in the incoming calls dial information conveyed directly to the respective communication terminals of the private communications system. For this purpose, both the number of the calling and the called of the communication terminal is inserted into the signaling information of the incoming calls. The inserted phone numbers of the calling and called communication terminal are also detected and transmitted via the application interface to the application device described at the outset. In the application device in to activating or einzurichtendes feature depending on the detected numbers is including at least entered a part of the detected numbers for a communication terminal of the private communication system, said to be entered feature is determined by the number of virtual feature communication terminal. For example, two feature-communication terminals are provided - one for the feature call forwarding and another for the callback feature - so that to be entered feature such as call forwarding or call is determined by the number of the respective performance feature communication terminal.

A major advantage of the method is the fact that an "external setting or activate", ie, activation, or a setting of a communication terminal of a public communications network is possible, and only in the application device a corresponding program-implemented application is to implement and the communication system initially described remains unchanged. Furthermore, the realized in the application device application through inputs to its user interface - be modified in a simple manner, whereby a maximum flexibility to set up and activate different features for different communication terminals groups is achieved - at a personal computer keyboard.

In a set up callback feature the performance feature communication terminal a of this callback feature indicating number is assigned. In the application device a call is registered, provided that within a predetermined time period at least one incoming, unsuccessful call for the respective communication terminal and a directed to a power characteristic terminal, incoming call are detected, in which the telephone numbers of the calling communication terminal match. This means that will only be set up and entered a callback for a communication terminal, provided, one of a communication terminal of the public communications network incoming call to the respective communication terminal was unsuccessful within a specified period, such as two minutes and an additional incoming call from the same communication terminal the public communications network has been detected at a special performance feature communication terminal. In the application device a call is made by the inventive submit a recall for a respective, connected to the private communication system communication terminal according to a reported by the communication system activity of the respective communication terminal for this introduced - claim 3. The main advantage of this measure is that this setting or . activating a recall will not be initiated and controlled in the communication system, but in the application device, wherein only reported by an input Illustrated communication system, the activity of the respective communication terminal. The recall is advantageously initiated and controlled by administration and maintenance instructions, which are transmitted via the application interface to the communications system. In communication system, a connection is initiated to the respective calling communication terminal in the public communication network from the respective communication terminal according to the administration and maintenance instructions - claim. 4

In a set up feature call forwarding the performance feature communication terminal a performance feature call forwarding indicating number is assigned and in the application device (PC) will add a call forwarding for the respective communication terminal unless a directed to the respective virtual feature-commu-nikationsendgerät, incoming call is detected , According to a first variant for the respective communication terminal of the private communication system in the application device previously registered or given a call divert number - for example, is registered or set the number of the home office via the user interface of the application device as Call Forwarding number. Using the application device is a directed to this incoming call is to an inventive Add a call forwarding for one of the communication terminals redirected to a level determined by the Call Forwarding number communication terminal - claim 5. Alternatively, the call divert number to be inserted in an incoming call, the on the feature communication terminal is addressed. This call divert number is also recorded in the communication system and transmitted to the application device and stored in this - claim. 6

According to an advantageous development of the method the call forwarding is for a Sign of an incoming call, the for the call forwarding is directed to a communication terminal of the private communication system and set up initiated by transmitting operational instructions on the application interface to the communications system. This is in accordance with the maintenance instructions of the incoming call to a specified by the Call Forwarding number communication terminal - diverted - - in the public communication network or private communication system of claim 7. By this Sign of the incoming call and-initiating the call forwarding by the application device is a complete implementation of the method according to the invention in the application device possible, ie the initially described private communication system remains unchanged.

Further advantageous embodiments of the inventive method and an application device for performing the method according to the invention is described in the further claims.
