Abstract: A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a mobile communication network. The controller determines whether the mobile communication network supports IMS services. The controller establishes a Packet Data Network (PDN) connection or a Protocol Data Unit (PDU) session with the mobile communication network for the IMS services via the wireless transceiver in response to the mobile communication network supporting the IMS services. The controller sends application data on the PDN connection or PDU session via the wireless transceiver.
