Method and apparatus for supporting tune-away in dual-sim dual-standby mobile devices

A computer program product, comprising:

• a computer-readable medium comprising executable code for:
• setting a first subscription of a first subscriber identity module (SIM) of a user equipment (UE) as a designated data subscription (DDS), wherein the first subscription supports only first technology type communication services;
• and
• setting a second subscription of a second SIM of the UE to support only the first technology type communication services in response to setting the first subscription as the DDS, wherein the second subscription is able to support both the first technology type communication services and second technology type communication services different than the first technology type communication services.

An apparatus for supporting tune-away, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor, wherein the at least one processor is configured to:
• set a first subscription of a first subscriber identity module (SIM) of a user equipment (UE) as a designated data subscription (DDS), wherein the first subscription supports only first technology type communication services;
• and
• set a second subscription of a second SIM of the UE to support only the first technology type communication services in response to setting the first subscription as the DDS, wherein the second subscription is able to support both the first technology type communication services and second technology type communication services different than the first technology type communication services.
