Abstract

A power management system is described where the handset can enter sleep or hibernation mode for a particular service, when the particular service is either not used or not available. The handset is capable of using the service, even in response to a non-user initiated incoming request for communication. The handset receives the request over the active service. The handset can then check for the availability of the inactive service, activate it, and a selection can be made between them.

Claims

1. A method for selecting a service, said method comprising:

receiving an event;

determining if one type of service is available;

registering the one type of service;

comparing the one type of service with a second type of service;

selecting between the one type of service and the second type of service;

responding to the event using the selected type of service.

2. The method of claim 1, wherein the event is a user initiated event.

3. The method of claim 1, wherein the event is an incoming request for communication.

4. The method of claim 1, where the one type of service is cellular service.

5. The method of claim 1, where the second type of service is wi-fi service.

6. The method of claim 1, where the one type of service is wi-fi service.

7. The method of claim 1, where the second type of service is cellular service.

8. A method for routing an incoming request for a communication, said method comprising:

receiving the incoming request for the communication;

locating the receiving handset in one network;

alerting the receiving handset over the one network;

receiving a signal from the handset indicating to send the request for the communication over a selected network;

sending the request for the communication over the selected network.

9. The method of claim 8, wherein the one network is a cellular network, and the selected network is a wi-fi network.

10. The method of claim 8, wherein the one network is a cellular network and the selected network is the cellular network.

11. The method of claim 8, wherein the one network is a wi-fi network, and the selected network is a cellular network.

12. The method of claim 8, wherein the one network is a wi-fi network and the selected network is the wi-fi network.
