Mobile fast alerting
View Patent ↗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.
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.
