Apple patents phone feature to juggle two active SIM cards

Apple has been granted a patent for a method that helps phones with two active SIM cards manage their data connections. The system decides which network connection to prioritize when both are busy, using the size of the incoming data as a factor to determine which task to pause.

Why it mattersThis improves how dual-SIM phones handle background updates and calls without one connection dropping the other.

In the filing’s own words

Methods and apparatuses are disclosed for scheduling radio resource control (RRC) processing for a dual-SIM dual-active (DSDA) user equipment (UE) connected to a plurality of networks. In one example embodiment, a UE may be configured to implement operations including: receiving a request to process a first RRC message for a first RRC task for a first SIM card from a first network; receiving a request to process a second RRC message for a second RRC task for a second SIM card from a second network; and performing an arbitration decision to decide whether to prioritize the implementation of the first RRC task for the first SIM card or the second RRC task for the second SIM card.

What exactly they claim (claim 1)

1. A method for scheduling radio resource control (RRC) processing for a dual-subscriber identity module (SIM) dual-active (DSDA) user equipment (UE) connected to a plurality of networks comprising: receiving a request to process a first RRC message for a first RRC task for a first SIM card from a first network; receiving a request to process a second RRC message for a second RRC task for a second SIM card from a second network; and performing an arbitration decision, wherein the arbitration decision implements a pre-emption based on an RRC message size process, to: prioritize implementation of the first RRC task and suspend processing of the second RRC task, or prioritize implementation of the second RRC task and suspend processing of the first RRC task based on the second RRC message being of a larger size than the first RRC message while the RRC message is being processed, where the implementation of the second RRC task comprises processing the second RRC message, and wherein suspending processing of the first RRC task comprises pre-empting the first RRC message.
