    Abstract: Aspects of the present disclosure provide techniques and apparatus for improving user experience of a voice call associated with a simultaneous voice and long-term evolution (SV-LTE) device (e.g., improving silent redial during a mobile originated (MO) call or mobile terminated (MT) call by a SV-LTE device. A method for wireless communications by a user equipment (UE) capable of communicating via a first packet-based radio access technology (RAT) and a second circuit-switched RAT is provided. The method generally includes detecting initiation of a mobile originated (MO) call, attempting to establish a connection with the first RAT prior to sending a session initiation protocol (SIP) message for the MO call, determining whether the connection is successfully established, and, if the connection is successfully established, sending the SIP message. Numerous other aspects are provided.

    Abstract: Methods and apparatus are provided for avoiding attempts by a UE to attach to a RAT network when that RAT network is unavailable. According to certain aspects, the UE may detect scenarios when the RAT network is unavailable and take preemptive action to prevent the UE from attempting to acquire service on that RAT. For example, the UE may effectively remove that RAT from a list of supported RATs by sending a UE capability message indicating that RAT is not supported, which may prevent network-initiated transitions of the UE to that RAT. The UE may also remove the unavailable RAT from an internal list of supported RATs, which may prevent UE-initiated transitions to that RAT.

    Abstract translation: 提供了方法和装置，以避免当该RAT网络不可用时，UE尝试附着到RAT网络。 根据某些方面，当RAT网络不可用时，UE可以检测情况，并且采取抢先行动来防止UE尝试在该RAT上获取服务。 例如，UE可以通过发送指示不支持RAT的UE能力消息来有效地从支持的RAT的列表中移除该RAT，这可能阻止UE发起到该RAT的网络发起的转换。 UE还可以从支持的RAT的内部列表中去除不可用的RAT，这可以防止UE发起到该RAT的转换。
