Abstract: A user equipment (UE) may camp on a network following a SIM bootup. Specifically, the UE may determine that a SIM implementation module of the UE includes a first SIM application (e.g., USIM) associated with a first cellular radio access technology (RAT) (e.g., LTE) and a second SIM application (e.g., CSIM) associated with a second cellular RAT (e.g., CDMA). The UE may then initialize the first SIM application and the second SIM application. The UE may determine whether the network is configured to support both voice and data communications using the first cellular RAT. If so, the UE may initiate camping on the network with the first cellular RAT in response to determining that the first SIM application is ready, but before the second SIM application is ready. If not, the UE may wait until both the first and second SIM applications are ready before initiating camping on the network.

Abstract translation: 用户设备（UE）可以在SIM启动之后驻留在网络上。 具体地，UE可以确定UE的SIM实现模块包括与第一蜂窝无线电接入技术（RAT）（例如，LTE）和第二SIM应用（例如，CSIM）相关联的第一SIM应用（例如，USIM） 与第二细胞RAT（例如，CDMA）相关联。 然后，UE可以初始化第一SIM应用和第二SIM应用。 UE可以确定网络是否被配置为支持使用第一蜂窝RAT的语音和数据通信。 如果是，则UE可以响应于确定第一SIM应用准备就绪，但在第二SIM应用准备好之前，可以利用第一蜂窝RAT在网络上启动野营。 如果不是，则在启动在网络上的野营之前，UE可以等待直到第一和第二SIM应用都准备就绪。
