Abstract
A user equipment (UE) employs a Universal Integrated Circuit Card (UICC) suspend algorithm when the UE is in an out-of-service (OOS) condition. When a modem of the UE enters an OOS sleep mode, the modem executes the UICC suspend algorithm to reduce activity at the UICC and conserve power. When the modem wakes up for network signal scanning, the modem executes a UICC resume algorithm to process any incoming commands. The UE thereby conserves power while in the OOS condition.
