Abstract

A mobile device configured for communication in both packet and circuit switched domains. The mobile device includes a domain selector. The domain selector is configured, responsive to selection by a user of one of the packet switched and circuit switched domains, to promote mobile device communication via the selected one of the packet switched and circuit switched domains.

Claims

1. A mobile device configured for communication in both packet switched and circuit switched domains, comprising:

a domain selector configured, upon receipt of an incoming call via a first domain that is one of the packet switched and circuit switched domains, to determine, by the mobile device, a selection of a second domain in which to accept the incoming call, wherein the second domain is the other one of the packet switched and circuit switched domains other than the first domain, and wherein the domain selector is further configured to send the selection of the second domain to a technology selector; and

the technology selector configured to transmit a message, by the mobile device, responsive to the incoming call in the first domain to a network element via a wireless communications network, wherein the network element is capable of interpreting the message, the interpreting comprising determining that the incoming call will be established in the second domain and setting up, by the mobile device, the incoming call via the second domain.

2. The mobile device of claim 1, wherein the network technology selected by the technology selector is one of a WLAN, GPRS, WiMAX, and CDMA1x EV-DO technologies when the selected second domain is the packet switched domain.

3. The mobile device of claim 1, wherein the network technology selected by the technology selector is one of a CDMA 1x, UMTS, and GSM technologies when the selected second domain is the circuit switched domain.

4. The mobile device of claim 1, further comprising:

a user interface configured to identify the first domain and receive the selection of the second domain.

5. The mobile device of claim 4, wherein the user interface is further configured to provide information including at least one of cost and quality data about the first domain and the second domain.

6. The mobile device of claim 1, wherein the technology selector is further configured to determine whether the network accepts or rejects the selection of the second domain based upon network availability, and if the selection of the second domain is rejected by the network, automatically selecting the first domain.

7. The mobile device of claim 6, wherein network availability includes one of availability of network resources and network load balancing requirements.

8. The mobile device of claim 1, wherein the message is one of a Setup message or Invite message.

9. A method in a mobile device for selecting a communication domain, comprising:

receiving, at the mobile device, an incoming call via a first domain that is one of a packet switched and circuit switched domains;

determining, at the mobile device, a selection of a second domain in which to accept the incoming call, the second domain being the other one of the packet switched and circuit switched domains other than the first domain;

communicating, from the mobile device, a message responsive to the incoming call in the first domain to a network element via a wireless communications network, wherein the network element is capable of interpreting the message, the interpreting comprising determining that the incoming call will be established in the second domain;

setting up, at the mobile device, a new communications connection in the second domain.

10. The method of claim 9, further comprising:

indicating the first domain via a user interface as a default domain; and

providing an input component on the user interface to enable selection of the second domain as an override domain.

11. The method of claim 9, wherein said setting up the new communications connection in the second domain comprises:

if the second domain is unavailable, causing the incoming call to be established in the first domain; and

causing a handover of the incoming call to the selected second domain upon moving to a geographic area where the selected second domain is available.

12. The method of claim 11, further comprising:

indicating the second domain is unavailable via a user interface; and

providing an input component on the user interface to enable confirmation to use the first domain.

13. The method of claim 9, wherein the first domain is a default domain associated with a connection preference, and wherein the selected second domain is different from the default domain.

14. The method of claim 9, wherein

communicating the message includes transmitting the selection of the second domain.

15. The method of claim 9, further comprising:

determining whether the wireless communications network has accepted or rejected the selection of the second domain; and

if the selection of the second domain is rejected by the wireless communications network, automatically selecting the first domain.

16. The method of claim 9, wherein the message is one of a Setup message or Invite message.

17. A method in a dual mode mobile device, comprising:

receiving an incoming call in a packet switched domain;

determining a selection at the dual mode mobile device to accept the incoming call in a circuit switched domain, wherein determining the selection occurs during an initialization of a communications connection responsive to receiving the incoming call;

transmitting a message used to indicate the selection of the circuit switched domain, wherein the message is transmitted to a network element configured to interpret the message and cause the incoming call to be established in the circuit switched domain; and

setting up a new communication connection for the incoming call in the circuit switched domain.

18. The method of claim 17, wherein determining the selection is based upon a preference configuration at the mobile device.

19. The method of claim 17, wherein the message is one of a Setup message or Invite message.
