Abstract

A predictive wakeup function for Push-to-Talk-over Cellular (PoC) call setup optimizations in a cellular mobile phone network. In performing the predictive wakeup for call setup optimizations, an originating mobile transmits an event trigger to a real-time exchange that interfaces to a mobile switching center in the cellular mobile phone network. The real-time exchange transmits a wakeup message to one or more terminating mobiles of predicted participants, in order to transition the terminating mobiles of the predicted participants from a dormant state to an active state prior to a call being setup with the terminating mobiles of the predicted participants. The terminating mobiles of the predicted participants are identified by a predictive wakeup mechanism before the originating mobile sends a list of one or more terminating mobiles of actual participants to the real-time exchange. The predicted participants may be determined based on static or dynamic information, including heuristics involving calling patterns.

Claims

1. A system for providing advanced voice services in a cellular telephone network, comprising:

a cellular telephone network for making calls between mobiles;

at least one real-time exchange that interfaces to the cellular telephone network to perform advanced voice services, the advanced voice services including an instant two-way half-duplex voice call within a group of users of the cellular telephone network;

wherein an originating mobile transmits an event trigger to the real-time exchange, and the real-time exchange transmits a wakeup message to one or more terminating mobiles of predicted participants, in order to transition the terminating mobiles of the predicted participants from a dormant state to an active state prior to a call being setup with the terminating mobiles of the predicted participants; and

wherein the terminating mobiles of the predicted participants are identified by a predictive wakeup mechanism before the originating mobile sends a list of one or more terminating mobiles of actual participants to the real-time exchange.

2. The system of claim 1, wherein the real-time exchange sets up the advanced voice services toward the terminating mobiles of the actual participants, after receiving the list of the terminating mobiles of the actual participants.

3. The system of claim 1, wherein the event trigger is transmitted from the originating mobile when a user logs into a client on the originating mobile.

4. The system of claim 1, wherein the event trigger is transmitted from the originating mobile when a user navigates a contact list.

5. The system of claim 4, wherein the event trigger is transmitted from the originating mobile when a user selects one or more contacts or groups from the contact list.

6. The system of claim 1, wherein the event trigger is transmitted from the originating mobile when a user navigates a call history.

7. The system of claim 6, wherein the event trigger is transmitted from the originating mobile when a user selects one or more entries from the call history.

8. The system of claim 1, wherein the predicted participants are determined based on static or dynamic information.

9. The system of claim 1, wherein the participants are determined based on heuristics involving calling patterns.

10. The system of claim 9, wherein the heuristics involving calling patterns include:

all time most used contacts, most recently used contacts, time of day most used contacts, last used contacts, contacts involved in long duration of sessions, incoming or outgoing direction of sessions with contacts, level of activity of contacts, or active participants in a group call.

11. The system of claim 1, wherein the predictive wakeup mechanism is performed by the originating mobile.

12. The system of claim 1, wherein the predictive wakeup mechanism is performed by the real-time exchange.

13. A method of providing advanced calling services in a cellular telephone network, comprising:

making calls between mobiles in a cellular telephone network;

interfacing at least one real-time exchange to the cellular telephone network to perform advanced voice services, the advanced voice services including an instant two-way half-duplex voice call within a group of users of the cellular telephone network;

wherein an originating mobile transmits an event trigger to the real-time exchange, and the real-time exchange transmits a wakeup message to one or more terminating mobiles of predicted participants, in order to transition the terminating mobiles of the predicted participants from a dormant state to an active state prior to a call being setup with the terminating mobiles of the predicted participants; and

wherein the terminating mobiles of the predicted participants are identified by a predictive wakeup mechanism before the originating mobile sends a list of one or more terminating mobiles of actual participants to the real-time exchange.

14. The method of claim 13, wherein the real-time exchange sets up the advanced voice services toward the terminating mobiles of the actual participants, after receiving the list of the terminating mobiles of the actual participants.

15. The method of claim 13, wherein the event trigger is transmitted from the originating mobile when a user logs into a client on the originating mobile.

16. The method of claim 13, wherein the event trigger is transmitted from the originating mobile when a user navigates a contact list.

17. The method of claim 16, wherein the event trigger is transmitted from the originating mobile when a user selects one or more contacts or groups from the contact list.

18. The method of claim 13, wherein the event trigger is transmitted from the originating mobile when a user navigates a call history.

19. The method of claim 18, wherein the event trigger is transmitted from the originating mobile when a user selects one or more entries from the call history.

20. The method of claim 13, wherein the predicted participants are determined based on static or dynamic information.

21. The method of claim 13, wherein the participants are determined based on heuristics involving calling patterns.

22. The method of claim 21, wherein the heuristics involving calling patterns include:

all time most used contacts, most recently used contacts, time of day most used contacts, last used contacts, contacts involved in long duration of sessions, incoming or outgoing direction of sessions with contacts, level of activity of contacts, or active participants in a group call.

23. The method of claim 13, wherein the predictive wakeup mechanism is performed by the originating mobile.

24. The method of claim 13, wherein the predictive wakeup mechanism is performed by the real-time exchange.
