Controlling a call setup process
A call setup process ( 28 ) in a telecommunication device ( 10 ) is controlled, wherein the telecommunication device ( 10 ) receives a user command ( 22 ) to set up a call, initiates the call setup process ( 28 ), determines that the call is likely to reach a voicemail system ( 14 ), and, in response to the determination that the call is likely to reach the voicemail system ( 14 ), automatically terminates the call setup process ( 28 ). A telecommunication device ( 10 ) comprises related features. A telecommunication network ( 12 ) is adapted to support or implement a determination whether or not an incoming call is forwarded to the voicemail system ( 14 ). The invention improves the user experience if a called party does not personally answer a telephone call.
1. A method for controlling a call setup process in a telecommunication device, wherein the telecommunication device is a mobile communication device, the method comprising:
receiving at the mobile communication device a user command to set up a call;
initiating the call setup process;
determining at the mobile communication device that the call is likely to reach a voicemail system, wherein the mobile communication device determines that the call is likely to reach a voicemail system upon receiving a call forwarding notification; and
in response to the determination that the call is likely to reach the voicemail system, the mobile communication device automatically terminating the call setup process without any user input.
2. The method according to claim 1 , wherein the telecommunication device automatically terminates the call setup process before any connection is established.
3. The method according to claim 1 , wherein the telecommunication device notifies the user after terminating the call setup process.
4. The method according to claim 1 , wherein the mobile communication device has a wireless telecommunication function, and wherein said telecommunication function is at least one of a GSM telecommunication function and a UMTS telecommunication function.
5. A method for controlling a call setup process in a telecommunication device, wherein the telecommunication device is a mobile communication device, the method comprising:
receiving at the mobile communication device a user command to set up a call;
initiating the call setup process;
determining, at the mobile communication device, that the call is likely to reach a voicemail system, wherein the telecommunication device determines that the call is likely to reach a voicemail system upon receiving a call forwarding notification that passes at least one test performed by the telecommunication device; and
in response to the determination that the call is likely to reach the voicemail system, the mobile communication device automatically terminating the call setup process without any user input.
6. The method according to claim 5 , wherein the telecommunication device automatically terminates the call setup process before any connection is established.
7. The method according to claim 5 , wherein the at least one test comprises checking a call forwarding type stated in the call forwarding notification.
8. The method according to claim 5 , wherein the at least one test comprises analyzing a call forwarding target number contained in the call forwarding notification.
9. The method according to claim 8 , wherein the analyzing comprises checking whether the call forwarding target number or a part thereof corresponds to a voicemail system number.
10. The method according claim 8 , wherein the analyzing comprises checking whether the call forwarding target number contains the number of the called subscriber or a part of the number of the called subscriber.
11. The method according to claim 5 , wherein the telecommunication device notifies the termination of the call setup process to the user.
12. The method according to claim 5 , wherein the mobile communication device has a wireless telecommunication function, and wherein said telecommunication function is at least one of a GSM telecommunication function and a UMTS telecommunication function.
13. A telecommunication device that is adapted for controlling a call setup process, wherein the telecommunication device is a mobile communication device, and wherein:
the mobile communication device is configured to receive a user command to set up a call;
the mobile communication device is configured to initiate the call setup process in response to receiving the user command;
the mobile communication device is configured to determine that the call is likely to reach a voicemail system, wherein the telecommunication device determines that the call is likely to reach a voicemail system upon receiving a call forwarding notification; and
the mobile communication device is configured to automatically terminate the call setup process, without any user input, before any connection is established in response to the determination that the call is likely to reach the voicemail system.
14. The telecommunication device according to claim 13 , wherein the telecommunication device offers a standard call setup command and a modified call setup command, the modified call setup command initiating the call setup process.
15. A telecommunication device that is adapted for controlling a call setup process, wherein the telecommunication device is a mobile communication device, and wherein:
the mobile communication device is configured to receive a user command to set up a call;
the mobile communication device is configured to initiate the call setup process in response to receiving the user command;
the mobile communication device is configured to determine that the call is likely to reach a voicemail system, wherein the telecommunication device determines that the call is likely to reach a voicemail system upon receiving a call forwarding notification that passes at least one test performed by the telecommunication device; and
the mobile communication device is configured to automatically terminate the call setup process, without any user input, before any connection is established in response to the determination that the call is likely to reach the voicemail system.
16. The telecommunication device according to claim 15 , wherein the telecommunication device offers a standard call setup command and a modified call setup command, the modified call setup command initiating the call setup process.
17. The method according to claim 1 , wherein the call forwarding notification indicates the call forwarding target number.
18. The method according to claim 5 , wherein the call forwarding notification indicates the call forwarding target number.
19. The telecommunications device according to claim 13 , wherein the call forwarding notification indicates the call forwarding target number.
20. The telecommunications device according to claim 15 , wherein the call forwarding notification indicates the call forwarding target number.
