Mobile communications device and a method for controlling a mobile communications device

1. A mobile communications device comprising a radio processing circuit and a baseband processing circuit adapted to interact with the radio processing circuit, the mobile communications device configured to:

receive a page;

obtain message identification information identifying a core network domain from the page;

process the obtained message identification information by comparing the core network domain obtained from the page to a predefined list of core network domain types; and

control an ongoing network connection resulting from the processed message identification information by suspending the ongoing network connection by creating an unscheduled gap, establishing a network communication control connection during the unscheduled gap, and releasing the network communication control connection and returning to an idle state when the core network domain is other than one of the stored core network domain types and is established with a packet switched core network domain.

2. The mobile communications device of claim 1 ,

wherein the page is for a first subscriber identity module.

3. The mobile communications device of claim 2 ,

wherein the first subscriber identity module is a multi-radio access technology subscriber identity module.

4. The mobile communications device of claim 1 ,

wherein the ongoing network connection is on a second subscriber identity module.

5. The mobile communications device of claim 4 ,

wherein the second subscriber identity module is a 2G only subscriber identity module.

6. The mobile communications device of claim 1 ,

wherein the controlling of the ongoing network connection further comprises:

reconfiguring the network communication control connection to receive session signaling.

7. The mobile communications device of claim 1 , further comprising:

receiving session signaling indicated in the page when the core network domain is one of the stored core network domain types and is established with an IMS (internet protocol multimedia subsystem) core network domain.

8. The mobile communications device of claim 7 , further comprising:

obtaining at least one of a caller identification and an SMS message from the session signaling.

9. The mobile communications device of claim 1 ,

wherein the ongoing network connection is resumed when the unscheduled gap exceeds a predetermined amount of time.

10. The mobile communications device of claim 1 ,

wherein the ongoing network connection is resumed following obtaining at least one of a caller identification and an SMS message.

11. The mobile communications device of claim 1 ,

wherein the processing of the obtained message identification information comprises:

arbitrating between communication resources for a first subscriber identity module and a second subscriber identity module.

12. The mobile communications device of claim 11 ,

wherein the communication resources comprise at least one receiver and at least one transmitter.

13. The mobile communications device of claim 1 ,

wherein the predefined list of core network domain types comprises at least one of a packet-switched core domain and/or an IMS (internet protocol multimedia subsystem) core network domain.

14. The mobile communications device of claim 1 ,

wherein the processing the obtained message identification information further comprises:

comparing the core network domain obtained from the page to a core network domain of the ongoing network connection.

15. A method for controlling a mobile communications device in response to a page comprising:

receiving a page;

obtaining message identification information identifying a core network domain from the page;

processing the obtained message identification information by comparing the core network domain obtained from the page to a predefined list of core network domain types; and

controlling an ongoing network connection resulting from the processed message identification information

suspending the ongoing network connection by creating an unscheduled gap;

establishing a network communication control connection during the unscheduled gap; and

receiving session signaling indicated in the page when the core network domain is one of the stored core network domain types and is established with an IMS (internet protocol multimedia subsystem) core network domain or releasing the network communication control connection and returning to an idle state when the core network domain is other than one of the stored core network domain types and is established with a packet switched core network domain.

16. A mobile communications device comprising a radio processing circuit and a baseband processing circuit adapted to interact with the radio processing circuit, the mobile communications device configured to:

receive a page;

obtain message identification information identifying a core network domain from the page;

process the obtained message identification information by comparing the core network domain obtained from the page to a predefined list of core network domain types; and

control an ongoing network connection resulting from the processed message identification information by suspending the ongoing network connection by creating an unscheduled gap, establishing a network communication control connection during the unscheduled gap, and receiving session signaling indicated in the page when the core network domain is one of the stored core network domain types and is established with an IMS (internet protocol multimedia subsystem) core network domain.

17. The mobile communications device of claim 16 , further comprising:

obtaining at least one of a caller identification and an SMS message from the session signaling.
