Abstract

Embodiments described herein relate to a method of managing communications for a wireless communication device having a first Subscriber Identity Module (SIM) associated with a first subscription and a second SIM associated with a second subscription, the method including, but not limited to, determining that the first subscription is a Default Data Subscription (DDS), deactivating at least one first Packet Data Network (PDN) associated with the second subscription, and communicating via at least one second PDN associated with the second subscription, wherein the at least one first PDN is different from the at least one second PDN.

Claims

1. A method of managing communications for a wireless communication device having a first Subscriber Identity Module (SIM) associated with a first subscription and a second SIM associated with a second subscription, the method comprising:

determining that the first subscription is a Default Data Subscription (DDS);

deactivating at least one first Packet Data Network (PDN) associated with the second subscription; and

communicating via at least one second PDN associated with the second subscription, wherein the at least one first PDN is different from the at least one second PDN.

2. The method of claim 1, wherein deactivating the at least one first PDN associated with the second subscription comprises sending a first indication message to a network of the second subscription indicating that the at least one first PDN associated with the second subscription is deactivated.

3. The method of claim 2, wherein the first indication message is an Over-the-Air (OTA) signaling message.

4. The method of claim 1, wherein communicating via the at least one second PDN associated with the second subscription comprises receiving pages for the at least one second PDN associated with the second subscription.

5. The method of claim 1, wherein the at least one first PDN associated with the second subscription is deactivated in response to determining that the first subscription is the DDS.

6. The method of claim 1, further comprising determining that the second subscription is a non-DDS.

7. The method of claim 6, wherein the at least one first PDN associated with the second subscription is deactivated in response to determining that the second subscription is a non-DDS.

8. The method of claim 1, wherein the at least one first PDN comprises an Internet PDN.

9. The method of claim 1, wherein the at least one second PDN comprises an Internet Protocol (IP) Multimedia Subsystem (IMS) PDN.

10. The method of claim 1, further comprising:

de-registering at least one first service of the second PDN; and

communicating via at least one second service of the second PDN, wherein the at least one first service is different from the at least one second service.

11. The method of claim 10, wherein the at least one first service of the second PDN comprises one or more of Rich Communication Services (RCS), File To Protocol (FTP) services, or a non-mandatory service.

12. The method of claim 10, wherein the at least one second service of the second PDN comprises one or more of Voice-Over-LTE (VoLTE) services, Video Technology (VT) services, Short Messaging Services (SMS) services, or another mandatory service.

13. The method of claim 10, wherein de-registering the at least one first service of the second PDN comprises sending a second indication message to a network of the second subscription indicating that the at least one first service associated with the second subscription is deactivated.

14. The method of claim 13, wherein the second indication message is an Over-the-Air (OTA) signaling message.

15. The method of claim 10, wherein communicating via at least one second service of the second PDN comprises receiving Session Initiation Protocol (SIP) packets for the at least one second service.

16. The method of claim 1, wherein:

the first subscription is a Long Term Evolution (LTE) subscription; and

the second subscription is a LTE subscription.

17. The method of claim 1, wherein the wireless communication device is a Multi-SIM-Multi-Standby (MSMS) device.

18. The method of claim 1, further comprising not communicating via the at least one first PDN associated with the second subscription.

19. A wireless communication device, comprising:

at least one radio frequency (RF) resource;

a processor configured to connect to a first Subscriber Identity Module (SIM) associated with a first subscription and to a second SIM associated with a second subscription, and configured to;

determine that the first subscription is a Default Data Subscription (DDS);

deactivate at least one first Packet Data Network (PDN) associated with the second subscription; and

communicate via at least one second PDN associated with the second subscription, wherein the at least one first PDN is different from the at least one second PDN; and

a memory.

20. The wireless communication device of claim 19, wherein the processor is configured to deactivate the at least one first PDN associated with the second subscription by sending a first indication message to a network of the second subscription indicating that the at least one first PDN associated with the second subscription is deactivated.

21. The wireless communication device of claim 20, wherein the first indication message is an Over-the-Air (OTA) signaling message.

22. The wireless communication device of claim 19, wherein the processor is configured to communicate via the at least one second PDN associated with the second subscription by receiving pages for the at least one second PDN associated with the second subscription.

23. The wireless communication device of claim 19, wherein the at least one first PDN comprises an Internet PDN.

24. The wireless communication device of claim 19, wherein the at least one second PDN comprises an Internet Protocol (IP) Multimedia Subsystem (IMS) PDN.

25. The wireless communication device of claim 19, wherein the processor is further configured to:

de-register at least one first service of the second PDN; and

communicate via at least one second service of the second PDN, wherein the at least one first service is different from the at least one second service.

26. The wireless communication device of claim 25, wherein:

the at least one first service of the second PDN comprises one or more of Rich Communication Services (RCS) or File To Protocol (FTP) services; and

the at least one second service of the second PDN comprises one or more of Voice-Over-LTE (VoLTE) services, Video Technology (VT) services, or Short Messaging Services (SMS) services.

27. The wireless communication device of claim 25, wherein the processor is configured to de-register the at least one first service of the second PDN by sending a second indication message to a network of the second subscription indicating that the at least one first service associated with the second subscription is deactivated.

28. The wireless communication device of claim 27, wherein the second indication message is an Over-the-Air (OTA) signaling message.

29. A method of managing communications for a wireless communication device having a first Subscriber Identity Module (SIM) associated with a first subscription and a second SIM associated with a second subscription, the method comprising:

determining that the first subscription is a Default Data Subscription (DDS);

de-registering at least one first service of a Packet Data Network (PDN) associated with the second subscription; and

communicating via at least one second service of the PDN associated with the second subscription, wherein the at least one first service is different from the at least one second service.

30. A wireless communication device, comprising:

at least one radio frequency (RF) resource;

a processor configured to connect to a first Subscriber Identity Module (SIM) associated with a first subscription and to a second SIM associated with a second subscription, and configured to;

determine that the first subscription is a Default Data Subscription (DDS);

de-register at least one first service of a Packet Data Network (PDN) associated with the second subscription; and

communicate via at least one second service of the PDN associated with the second subscription, wherein the at least one first service is different from the at least one second service; and

a memory.
