System enablers for multi-sim devices

An apparatus, comprising:

• a memory;
• and
• at least one processor in communication with the memory, wherein the at least one processor is configured to:
• generate instructions to maintain, with a network, idle mode connections for at least a first subscriber identity module (SIM) and a second SIM;
• generate instructions to transition, upon receiving a first page from the network, a first connection associated with the first SIM to a connected mode;
• receive, from the network, a second page intended for the second SIM, wherein the second page includes an indication of an associated paging cause of voice communications;
• generate instructions to transmit, to a first access and mobility function (AMF) associated with a first radio access technology (RAT), an indication that causes a release of the first connection and blocks paging from the first AMF that is associated with a lower priority than indicated in the indication;
• and
• generate instructions to initiate a radio connection to a second AMF in response to the second page.

A non-transitory computer readable memory medium storing program instructions executable by processing circuitry to cause a user equipment device (UE) to:

• maintain, with a network, idle mode connections for at least a first subscriber identity module (SIM) and a second SIM;
• transition, upon receiving a first page from the network, a first connection associated with the first SIM to a connected mode;
• receive, from the network, a second page intended for the second SIM, wherein the second page includes an indication of an associated paging cause of voice communications;
• transmit, to a first access and mobility function (AMF) associated with a first radio access technology (RAT), an indication that causes a release of the first connection and blocks paging from the first AMF that is associated with a lower priority than indicated in the indication;
• and
• initiate a radio connection to a second AMF in response to the second page.
