Abstract

Operating a communication terminal is disclosed. A communication session initiation message is received at a first time. An alerting process is initiated at a second time, the second time being later than the first time by a predetermined delay.

Claims

1. A method of operating a communication terminal, the method comprising:

receiving a communication session initiation message at a first time; and

initiating an alerting process at a second time, the second time being later than the first time by a predetermined delay.

2. The method of claim 1, wherein initiating the alerting process at the second time comprises:

starting a delay timer at the first time; and

initiating the alerting process when the delay timer reaches the predetermined delay.

3. The method of claim 1, wherein the predetermined delay is a value stored in the communication terminal.

4. The method of claim 1, wherein the predetermined delay is a value communicated to the communication terminal.

5. The method of claim 1, wherein the predetermined delay is a value communicated to the communication terminal in the communication session initiation message.

6. The method of claim 1, further comprising measuring a time interval from initiation of the alerting process to a user response to the alerting process at the communication terminal.

7. The method of claim 6, further comprising transmitting an indication of the measured time interval.

8. The method of claim 6, further comprising adjusting the predetermined delay based on the measured time interval.

9. The method of claim 6, further comprising:

measuring time intervals from the initiation of the alerting process to the user response to the alerting process at the communication terminal for a plurality of communication sessions;

analyzing the measured time intervals for the plurality of communication sessions; and

adjusting the predetermined delay based on the analysis.

10. The method of claim 1, wherein the alerting process comprises emitting at the communication terminal at least one of an audible alert, a visual alert, and a tactile alert.

11. The method of claim 1, wherein the alerting process comprises transmitting an alerting response.

12. The method of claim 11, wherein transmission of the alerting response is adapted to initiate indication of alerting at a session-originating communication terminal.

13. The method of claim 11, wherein the alerting response comprises a session initiation protocol (SIP) ringing message.

14. The method of claim 1, wherein the communication session initiation message comprises a session initiation protocol (SIP) invite message.

15. The method of claim 1, wherein the communication terminal is a mobile telephone.

16. The method of claim 1, wherein the communication session is a hybrid Voice over Internet Protocol (VoIP) call combining packet-based signaling with circuit-based media.

17. A method of operating a communications system, the method comprising:

sending a communication session initiation message to a communication terminal;

determining a first time at which the communication session initiation message is received at the communication terminal; and

initiating an alerting process at the communication terminal at a second time, the second time being later than the first time by a predetermined delay.

18. The method of claim 17, wherein initiating the alerting process at the second time comprises:

starting a delay timer at the first time; and

initiating the alerting process when the delay timer reaches the predetermined delay.

19. The method of claim 17, further comprising measuring a time interval from initiation of the alerting process to a user response to the alerting process at the communication terminal.

20. The method of claim 19, further comprising adjusting the predetermined delay based on the measured time interval.

21. The method of claim 19, further comprising:

measuring time intervals from initiation of the alerting process to the user response to the alerting process at the communication terminal for a plurality of communication sessions;

analyzing the measured time intervals for the plurality of communication sessions; and

adjusting the predetermined delay based on the analysis.

22. The method of claim 17, wherein the communications system comprises the communication terminal and a communications network element serving the communication terminal.
