The wireless transceiver performs wireless transmission and reception to and from a 3rd Generation Partnership Project (3GPP) network using a first Radio Access Technology (RAT). The controller establishes one or more radio bearers with the first 3GPP network via the wireless transceivers, and establishes a secure tunnel with a non-3GPP interworking gateway of a second 3GPP network via the radio bearers. The second 3GPP network utilizes a second RAT. Also, the controller registers, via the secure tunnel, an IP Multimedia Subsystem (IMS) service with an IMS server communicatively connected to the second 3GPP network, so as to make a voice call over the first 3GPP network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatuses and methods for voice call service provision","description":"A mobile communication device including a wireless transceiver and a controller is provided.
