Apparatuses, systems, and methods for enhancement of Wi-Fi calling for DSDS user equipment devices (UEs). The UE may register a first connection supported by a first SIM with IMS for VoWiFi based on a determination to prefer VoWiFi for the first SIM. The first SIM may be associated with a first subscription to a first RAN. The UE may include a second SIM that may be associated with a second subscription to a second RAN. The UE may register a second connection associated with the second SIM with the IMS for VoWiFi and/or VoLTE and initiate/receive, via the first connection supported by the first SIM, a VoWiFi call. A recommendation to handover the VoWiFi call from Wi-Fi to cellular data may be received and, based, at least in part, on the recommendation, the UE may register a second connection associated with the second SIM for IWLAN over cellular data.

DSDS Wi-Fi calling enhancements

A user equipment includes a radio frequency (RF) modem configured to wirelessly communicate with at least one mobile network operator and a wireless local area network (WLAN) modem configured to wirelessly communicate with at least one WLAN access point. The user equipment further includes a processor coupled to the RF modem and the WLAN modem and at least one memory storing executable instructions. The executable instructions are configured to manipulate at least one of the processor and the RF modem to establish a first cellular connection with a first mobile network operator based on a first subscription represented by a first subscriber identity, and virtualize the first cellular connection as a wireless local area network (WLAN) connection for use by one or more processes executed by the processor for a second subscription represented by a second subscriber identity.

Virtualization of cellular connection as wireless local area network connection

Systems, apparatuses, and methods for Internet resource sharing between multiple subscribers, for example, a first subscriber and a second subscriber, each of which may be in active communications with a cellular network or in a standby mode. It may be determined whether to use an internet connectivity provided by the first subscriber for an IP Multimedia Subsystem (IMS) service on the second subscriber. The second subscriber may conduct the IMS service via internal hotspot provided by the first subscriber or via the second subscriber's own cellular network, or switch between the two. A packet data network connection may be established to transport IMS data and signaling between the second subscriber and a gateway of the second network through the first network.
