Abstract

In the English translation document, please replace the abstract with the following: A method and to an arrangement for handling calls switched by private branch exchanges to a mobile communications network are provided. The mobile communications network and a branch exchange communicate with a control device in such a way that in switching of a call request originating from a communication device connected to the private branch exchange to a mobile communication terminal of the mobile communications network there is no call setup on the part of the private branch exchange when the mobile communication device has logged out.

Claims

1-17. -17. (canceled)

18. A method for handling calls switched by private branch exchanges to a mobile communications network, comprising:

communicating a log out of a mobile communication terminal of the mobile communications network to a control device; and

communicating information between a communication device connected to the private branch exchange and the control device;

wherein a switching of a call request from the communication device to the mobile communication terminal is such that there is no call setup on the part of the private branch exchange when the mobile communication device has logged out.

19. The method as claimed in claim 18, wherein when there is no call setup on the part of the private branch exchange, the method further comprising:

recording of a voice message is offered by the private branch exchange; and

storing a recorded voice message in a storage device associated with the private branch exchange such that the message is via the mobile communication terminal.

20. The method as claimed in claim 18, wherein the absence of the call setup is achieved by the private branch exchange blocking a call number associated with the mobile communication device.

21. The method as claimed in claim 18, wherein when the mobile communication device has logged in, a call is made to the mobile communication device via a connection to the mobile communication device executed on the part of the private branch exchange.

22. The method as claimed in claim 18, wherein the absence of the call setup is based on a first message sent by the control device to the private branch exchange.

23. The method as claimed in claim 22, wherein when the mobile communication device has logged in, a call is made to the mobile communication device via a connection to the mobile communication device executed on the part of the private branch exchange.

24. The method as claimed in claim 23, wherein the call is executed based of a second message sent by the control device to the private branch exchange.

25. The method as claimed in claim 24, wherein at least the first or second message is sent based on information transmitted to the control device about a change in the status of the mobile communication device.

26. The method as claimed in claim 25, wherein the change in status is detected in such a way that:

the mobile communication device establishes a call to a first extension of the private branch exchange,

the call is abandoned again immediately after it has been established,

the private branch exchange detects the call made, and

the private branch exchange detects the information associated with the mobile communication terminal.

27. The method as claimed in claim 25, wherein the change in status is detected in such a way that:

the mobile communication device establishes a call to a first port of the private branch exchange,

the call is abandoned again immediately after it has been established,

the private branch exchange detects the call that has been made, and

the private branch exchange detects the information associated with the mobile communication terminal.

28. The method as claimed in claim 18, wherein when the mobile communication device has logged in, a call is made to the mobile communication device via a connection to the mobile communication device executed on the part of the private branch exchange.

29. The method as claimed in claim 18, wherein a call number of the mobile communication device is detected as information.

30. The method as claimed in claim 18, wherein a status of the mobile communication device is reversed in each case by the establishment of the call.

31. An arrangement for handling calls switched by private branch exchanges to a mobile communications network, comprising:

a private branch exchange communicatively connected to a communication device;

a mobile communications network communicatively connected to a mobile communication terminal; and

a control unit device communicatively connected to the private branch exchange and the mobile communications network, the control unit device receives a log out of the mobile communication terminal from the mobile communications network, the log out is subsequently provided by the control unit device to the private branch exchange,

wherein a call from the communication device to the logged out mobile communication device is blocked by the private branch exchange

32. The arrangement as claimed in claim 31, wherein the call is blocked based on a directory number of the logged out mobile communication device.

33. The arrangement as claimed in claim 31, wherein the blocked call is forwarded to a message facility associated with the private branch exchanged.

34. The arrangement as claimed in claim 33, wherein a message is stored in a storage device associated with the private branch exchange in response to forwarding the call to the message facility, and wherein the stored message is retrievable by the mobile communication device.

35. An arrangement for handling calls switched by private branch exchanges to a mobile communications network, comprising:

a private branch exchange communicatively connected to a communication device;

a mobile communications network communicatively connected to a mobile communication terminal; and

a control unit device communicatively connected to the private branch exchange and the mobile communications network, the control unit device receives a log out of the mobile communication terminal from the mobile communications network,

wherein a first message is sent to the control unit device in response to a call from the communication device to the logged out mobile communication device, and

wherein the control unit blocks the set up by the private branch exchange.

36. The arrangement as claimed in claim 35, wherein the blocked call is forwarded to a message facility associated with the private branch exchanged.

37. The arrangement as claimed in claim 36,

wherein a message is stored in a storage device associated with the private branch exchange in response to forwarding the call to the message facility, and

wherein the stored message is retrievable by the mobile communication device.
