Abstract

A user equipment (UE) in a mobile network is configured to establish a first packet data network (PDN) connection between the UE and an Internet Protocol Multimedia Service (IMS) network of the mobile network via a wireless local area network (WLAN) access point. The first PDN connection is for implementing a voice call. The UE determines that at least one of the UE or the mobile network fails to support Voice over New Radio (VoNR). Responsive to determining that at least one of the UE or the mobile network fails to support Voice over New Radio (VoNR), the UE prevents itself from establishing a connection with a first radio access network (RAN) of the mobile network.
