Abstract:
A multi-SIM UE may perform network SIB acquisition for each network subscription. However, if the multi-SIM UE employs subscriptions for the same network these operations may be performed redundantly. By identifying that the UE is employing multiple subscriptions, the UE and network can perform a single SIB acquisition for multiple subscriptions, which reduces power consumption and optimize network signaling overhead. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE configured to determine that the UE is associated with a plurality of network subscriptions, the plurality of network subscriptions being associated with a network, select a network subscription from the plurality of network subscriptions, perform a random-access procedure using the network subscription, receive system information broadcast in response to the random-access procedure, and configure the plurality of network subscriptions at the UE based on the system information.
