Abstract

The invention relates to a method for call diversion in a telecommunication network, comprising a data network (1), a voice network (2), for the transmission of speech, a network server (7), for the speech network (2) and a management server (6), for the data network (1). According to the invention, the management server is interrogated about the state of a call from the user terminal (8) to the data network (1) and where an error in said call occurs a call transfer to a stored address is carried out by the network server (7).

Claims

1. A method to redirect calls in a telecommunications network, the telecommunications network has a switching server to provide call redirects to other locations in the telecommunications network and has an administration server to administer and control user services and network capacities in a data network, wherein an address for a call redirect is saved in the switching server or the administration server, comprising:

determining whether a call has arrived for a subscriber through the switching server;

transmitting an address of the subscriber to the administration server;

checking, with aid of the administration server, whether a terminal device is signed on to the subscriber address;

transmitting results of the check from the administration server to the switching server; and

redirecting the call to a prescribed address through the switching server if the administration server transmits the result that no terminal device is signed on to the subscriber address.

2. The method of redirecting calls in the telecommunications network according to claim 1, wherein the data network is a network with packet switching.

3. The method of redirecting calls in the telecommunications network according to claim 1, wherein the address for the call redirect is transmitted from the administration server to the switching server together with the result of the check, or is read out from a storage space on the switching server.

4. The method of redirecting calls in the telecommunications network according to claim 1, wherein the switching server does not execute a call redirect if a maximum number of call redirects to be performed in series is exceeded.

5. The method of redirecting calls according to claim 1, wherein the data network is a Local Area Network.

6. The method of redirecting calls according to claim 1, wherein the data network is the Internet.

7. A telecommunications network, comprising:

a data network to which a subscriber has access if a terminal device of the subscriber is signed on thereto;

a voice network configured for voice transmission to which the subscriber has access through the data network;

a switching server of the voice network that provides call redirects to other locations in the telecommunications network; and

an administration server that administers and controls user services and network capacities in the data network, wherein

at least one address for a call redirect is saved in the switching server or the administration server for the subscriber,

the switching server is configured to perform a query of the administration server when the subscriber is called from the voice network to determine whether the terminal device of the subscriber is signed on to the data network, and

the switching server executes a call redirect to the stored address when, as a result of the query of the administration server, a no sign-on is transmitted.

8. The telecommunications network according to claim 7, wherein the data network is a network with packet switching.

9. The telecommunications network according to claim 7, wherein the address for a call redirect is stored in the administration server of the data network and the administration server transmits the address to the switching server with a result of the query to determine if the terminal device of the subscriber is singed on to the data network.

10. The telecommunications network according to claim 7, wherein the switching server stores a maximum number of call redirects to be carried out in series.

11. The telecommunications network according to claim 7, wherein the data network, which is configured as a packet network, is the Internet and the administration server is a gatekeeper.

12. The telecommunications network according to claim 7, wherein the telecommunications network, which is configured as a packet network, is a Local Area Network and the administration server is a gatekeeper.
