    Abstract: A method of operating user equipment (UE) for detecting network capability. The method comprises identifying a preferred mode for a voice over long-term evolution (VoLTE) call handover operation from an LTE network to a non-LTE network in a first communication network. The preferred mode is associated with the first communication network. The method further comprises initiating a VoLTE call in a second communication network different than the first communication network, determining whether the second communication network is capable of supporting the preferred mode associated with the first communication network, and one of changing and maintaining the preferred mode based on a result of the determination.

    Abstract: User equipment (UE) includes a transceiver configured to transmit and receive information to/from a Wireless Fidelity (WiFi) access point. The UE includes processing circuitry coupled to the transceiver and configured to: determine a service provider associated with the WiFi access point based on a response to an ANQP query. The UE is configured to receive at least a portion of a management object (MO). The MO includes a trust field specifying whether the WiFi access point is trusted for WiFi offload by the service provider. The UE is configured to: in response to determining that the WiFi access point is trusted, send an L3 attach trigger. The UE is configured to: in response to determining that the WiFi access point is not trusted, establish an Internet Protocol security (IPsec) tunnel that the UE to an Evolved Packet Data Gateway through the untrusted WiFi access point.

    Abstract: A method, apparatus, and user equipment for wireless communication using evolved data packet gateway (ePDG) communication. The method includes identifying one or more wireless access points and a received signal strength indication for each of the one or more wireless access points. The method also includes identifying which of the one or more wireless access points supports ePDG communication. The method also includes selecting a wireless access point of the one or more wireless access points based on the received signal strength indication and whether the wireless access point supports ePDG communication. The method also includes connecting to an ePDG server through the wireless access point.

    Abstract: A method includes setting, using at least one processor of an electronic device that includes multiple subscriber identity module (SIM) cards, a maximum Network Address Translation (NAT) interval to be a maximum value among NAT keep-alive intervals associated with the multiple SIM cards. The method also includes triggering, using the at least one processor, a partial call setup from a first SIM card of the multiple SIM cards to a second SIM card of the multiple SIM cards. The method further includes determining, using the at least one processor, whether the electronic device receives the partial call setup. In addition, the method includes, in response to determining that the electronic device receives the partial call setup, setting, using the at least one processor, the NAT keep-alive interval for each of the multiple SIM cards to be equal to the maximum NAT interval.

    Abstract: A method includes generating a decision matrix for selection of a particular Non-3GPP InterWorking Function (N3IWF) server among a plurality of N3IWF servers, the decision matrix having multiple criteria including multiple N3IWF capabilities. The method also includes dynamically weighting at least one of the multiple criteria in the decision matrix, based on one or more adjustment factors. The method further includes applying a multi-attribute decision making technique to the decision matrix to select the particular N3IWF server, among the plurality of N3IWF servers, for a mobile device to connect to in a 5G network.
