Abstract

A method for call setup for a voice-over-long-term evolution (VoLTE) call on multi-subscriber identity module (SIM) multi-standby (MSMS) mobile communication device includes: receiving a long-term evolution (LTE) page; determining whether a WiFi connection is available; in response to determining that the WiFi connection is not available, determining whether the LTE page was received on a non-dedicated data subscription (DDS) subscription; and in response to determining that the LTE page was received on the non-DDS subscription, granting a highest priority for communication activities to an LTE page response on the non-DDS subscription.
