Selective tuning-away in multi-subscription wireless communication device
First Claim
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);
in response to determining that the first subscription is a DDS, deactivating all Packet Data Networks (PDNs) associated with the second subscription except for a first network, wherein the first network is an Internet Protocol (IP) Multimedia Subsystem (IMS) Packet Data Network (PDN);
de-registering, for the first network, all IMS services except for a first service selected from the group consisting of Voice-Over-LTE (VoLTE) services, Video Technology (VT) services, and Short Messaging Services (SMS) services; and
communicating via the first network using the first service.

13. A wireless communication device, comprising:
-
at least one radio frequency (RF) resource; a first Subscriber Identity Module (SIM) associated with a first subscription; a second SIM associated with a second subscription; a processor; and a memory storing instructions that, when executed by the processor, cause the wireless communication device to; determine that the first subscription is a Default Data Subscription (DDS); in response to a determination that the first subscription is a DDS, deactivate all Packet Data Networks (PDNs) associated with the second subscription except for a first network, wherein the first network is an Internet Protocol (IP) Multimedia Subsystem (IMS) PDN; de-register, for the first network, all IMS services except for a first service selected from the group consisting of Voice-Over-LTE (VoLTE) services, Video Technology (VT) services, and Short Messaging Services (SMS) services; and communicate via the first network using the first service. - View Dependent Claims (14, 15, 16, 17, 18)
