Abstract

A technique for leaving automatic call requests. A switch (SW) receives (2-2) a call setup request from an A terminal to a B terminal and detects (2-4) that the B terminal cannot take the call. The switch (SW) informs (2-6) the A terminal that the call setup request can be interpreted as an automatic call request to the B terminal. Upon receiving (2-8) an acknowledgment from the A terminal, the switch determines and temporarily stores (2-14) an identity of the A terminal. It then sends (2-18) the B terminal a data message that comprises an automatic call request that indicates the identity of the A terminal.

Claims

1. An automatic method for processing a call from a calling terminal to a called terminal that supports data messages, the method comprising:

receiving a call setup request from the calling terminal to the called terminal and detecting that the called terminal cannot respond to the call setup request;

characterized by

informing the calling terminal that the call setup request can be interpreted as an automatic call request to the called terminals;

receiving an acknowledgment from the calling terminal that that the call setup request is to be interpreted as an automatic call request;

determining and temporarily storing an identity of the calling terminal;

sending the called terminal a data message comprising an automatic call request that indicates the identity of the calling terminal.

2. A method according to claim 1, characterized by determining a textual identity of the calling terminal.

3. A method according to claim 2, characterized by determining said textual identity by means of a search to a data network.

4. A method according to claim 1, characterized in that, if said acknowledgment is not received, the call setup request is routed to voice mail.

5. A method according to claim 2, characterized by receiving a notification that a user of the calling terminal accepts a reverse-charge call from the called terminal.

6. A method according to claim 1, characterized in that the data message indicates identities of several calling terminals from which call setup requests were detected before sending the data message.

7. A method according to claim 1, characterized by installing in the called terminal a software agent for:

displaying an identity of each of one or more calling terminals indicated by one or more automatic call requests;

receiving an indication of a user-selected calling terminal; and

placing a call to the user-selected calling terminal.

8. A method according to claim 1, further comprising making an automatic callback call to the calling terminal.

9. A method according to claim 1, further comprising determining status information on pending call requests and sending said status information to the calling terminal.

10. A switching elementary for a mobile network, operable to switch calls between mobile terminals, the switching element comprising means for receiving a call setup request from the calling terminal to the called terminals and detecting that the called terminals cannot respond to the call setup request;

characterized by

means for informing the calling terminal that the call setup request can be interpreted as an automatic call request to the called terminals;

means for receiving an acknowledgment from the calling terminal that that the call setup request is to be interpreted as an automatic call request;

means for determining and temporarily storing an identity of the calling terminal; and

means for sending the called terminals a data message comprising an automatic call request that indicates the identity of the calling terminal.

11. A mobile terminal for a mobile network, characterized by means for receiving and displaying an identity of each of one or more calling terminals indicated by one or more automatic call requests.

12. A mobile terminal according to claim 11, characterized by means for receiving an indication of a user-selected calling terminal and means for placing a call to the user-selected calling terminal.

13. A mobile terminal according to claim 11, characterized by means for automatically placing a callback call to one of said one or more calling terminals.
