Abstract: A method for enhanced call control using User Equipment (UE)-triggered fallback procedure is provided. A UE starts a guard timer in response to initiating or receiving an Internet Protocol (IP) Multimedia Subsystem (IMS) call in a mobile communication network which utilizes a first Radio Access Technology (RAT). The UE determines whether a condition for call continuation in the mobile communication network is met when the guard timer expires. The UE triggers a fallback from the first RAT to a second RAT in response to the condition for call continuation in the mobile communication network not being met.

Abstract: A method for configuration enhancements on Access Point Name (APN) or Data Network Name (DNN) selection in a User Equipment (UE) is provided. The UE receives a message from a mobile communication network. In particular, the message includes information on an input source of an APN value or a DNN value. Based on the information, the UE uses the APN value or the DNN value to request establishment of a Packet Data Network (PDN) connection or a Protocol Data Unit (PDU) session with the mobile communication network.

Abstract: A Mobile communication network having a wireless transceiver, configured to perform wireless transmission and reception to and from a UE, and a controller, coupled to the wireless transceiver. The controller is configured to: send a message to the UE via the wireless transceiver, wherein the message comprises information for indicating an order and a priority of reading Access Point Name (APN) parameters or Data Network Name (DNN) parameters from a plurality of input sources, and wherein each input source comprises an APN value or a DNN value. The message comprises an IP Multimedia Subsystem (IMS) Management Object (MO), and the information is provided by an IMS configuration parameter in the IMS MO.

Abstract: A method, executed by a SUPL (Secure User Plane Location) Enabled Terminal (SET), is provided. The method includes the steps of: sending an INVITE request for an emergency call to a Call Session Control Function (CSCF) entity of an IP Multimedia Subsystem (IMS); and receiving a response to the INVITE request from the CSCF entity, wherein the response includes an SUPL INIT message.

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.

Abstract: A method for robust moving between a roaming Third Generation Partnership Project (3GPP) network and a non-3GPP network is provided. The method includes the steps of: connecting with a home 3GPP network over one of a roaming 3GPP network and a non-3GPP network by a User Equipment (UE); performing a first initial attach procedure with the home 3GPP network over the other of the roaming 3GPP network and the non-3GPP network by the UE in response to the UE moving from the one of the roaming 3GPP network and the non-3GPP network to the other of the roaming 3GPP network and the non-3GPP network; and keeping the connection over the one of the roaming 3GPP network and the non-3GPP network by the UE during the first initial attach procedure over the other of the roaming 3GPP network and the non-3GPP network.
