    Abstract: A method for reducing call failure rates on a multi-subscriber identity module (SIM) mobile communication device includes: selecting a first SIM camped on a visiting public land mobile network (VPLMN); attempting call initiation on the first SIM; determining whether call setup on the first SIM on the VPLMN is successful; in response to determining that the call setup on the first SIM is unsuccessful, determining if a second SIM is camped on a home public land mobile network (HPLMN); and in response to determining that the second SIM is camped on the HPLMN, selecting the second SIM camped on the HPLMN; and attempting call initiation using the second SIM.

    Abstract translation: 一种用于在多用户识别模块（SIM）移动通信设备上减少呼叫失败率的方法包括：选择驻留在访问公共陆地移动网络（VPLMN）上的第一SIM卡; 在第一SIM上尝试呼叫启动; 确定VPLMN上的第一SIM上的呼叫建立是否成功; 响应于确定第一SIM上的呼叫建立不成功，确定第二SIM是否驻留在家庭公共陆地移动网络（HPLMN）上; 并且响应于确定所述第二SIM卡驻留在所述HPLMN上，选择驻留在所述HPLMN上的所述第二SIM卡; 并使用第二SIM卡尝试呼叫启动。

    Abstract: Aspects of the present disclosure provide techniques and apparatus for wireless communication. In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE) that may support a first radio access technology (RAT) and a second RAT. The method generally includes: attempting to communicate with a base station (BS) of the first RAT; in response to an event, stopping the attempt to communicate with the BS of the first RAT; in response to stopping the attempt to communicate with the BS of the first RAT, attempting to connect to the second RAT; and in response to a successful connection to the second RAT: identifying a first value of a parameter associated with the event; comparing the value to a second value; and determining whether to perform an action associated with the first RAT based at least in part on the comparing.
