US 2024/0406708 A1 · DYNAMIC DEVICE CAPABILITY FOR MULTI-SIM/eSIM WIRELESS DEVICES DURING OUT-OF-SERVICE SCENARIOS

Abstract

The described embodiments relate to wireless communications, including methods and apparatus for dynamically adjusting device capability of a device that includes multiple subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs) during out-of-service scenarios. A multi-SIM/eSIM wireless device can include at least two SIM/eSIM profiles that each provide access to cellular wireless services. When an active SIM/eSIM profile enters an out-of-service (OOS) state or exits an OOS state, the multi-SIM/eSIM wireless device dynamically updates device capabilities to re-allocate device resources to one or more active SIM/eSIM profiles not in the OOS state to improve device performance. Device capabilities for the one or more active SIM/eSIM profiles not in the OOS state are also controlled to ensure the active SIM/eSIM profile in the OOS state has computing resources available to perform radio frequency (RF) scan procedures.

Dependent claims

A method for dynamic device capability by a multi-SIM/eSIM wireless device, the method comprising:

by a baseband component of the multi-SIM/eSIM wireless device:
detecting an out-of-service (OOS) condition for a second SIM/eSIM of a plurality of active SIMs/eSIMs that also includes a first SIM/eSIM in the multi-SIM/eSIM wireless device;
reconfiguring, responsive to detecting the OOS condition for the second SIM/eSIM, a cellular wireless modem of the multi-SIM/eSIM wireless device from a multi-SIM/eSIM state using the first SIM/eSIM and the second SIM/eSIM to a single SIM/eSIM state using the first SIM/eSIM;
detecting initiation of an OOS radio frequency (RF) scan procedure for the second SIM/eSIM;
blocking use of a maximum capability configuration for the first SIM/eSIM during the OOS RF scan procedure;
and
when the OOS RF scan procedure successfully detects a cellular wireless network for the second SIM/eSIM, reconfiguring the cellular wireless modem of the multi-SIM/eSIM wireless device from the single SIM/eSIM state using the first SIM/eSIM to the multi-SIM/eSIM state using the first SIM/eSIM and the second SIM/eSIM,
wherein:
the cellular wireless modem is restricted to a reduced capability configuration for each active SIM/eSIM while configured in the multi-SIM/eSIM state.
