User experience of a voice call associated with a device

摘要

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.

1. 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, the method comprising:
detecting initiation of a mobile originated (MO) call; generating a session initiation protocol (SIP) message for the MO call; attempting to establish a connection with the first RAT prior to queuing the SIP message for sending; determining whether the connection is successfully established; and if the connection is successfully established, sending the SIP message.
