    Abstract: A communications network may be used to convey Short Message Service (SMS) messages using the Internet Protocol (IP). User equipment may transmit an SMS-over-IP Session Initiation Protocol (SIP) message to wireless equipment over a high-bandwidth communications link. The wireless equipment may route the SMS-over-IP SIP message to the ePDG. When the high-bandwidth link is unavailable, the user equipment may transmit a compressed message to the proxy server over a low-bandwidth communications link. The proxy server may convert the compressed message into an SMS-over-IP SIP message that is transmitted to the ePDG. The proxy server may serve as a proxy for the first user equipment from the perspective of the ePDG. This may allow SMS message data to continue to be conveyed through the communications network even when the high-bandwidth communications link becomes unavailable.

    Abstract: Techniques are disclosed relating to a mobile device that communicates over short-range networks and long-range networks. In various embodiments, a mobile device includes one or more radios configured to communicate using a plurality of radio access technologies (RATs) including a cellular RAT and a short-range RAT. The mobile device may establish a first connection and a second connection with a network such that the first connection uses the short-range RAT and the second connection uses the cellular RAT. The mobile may collect information about the second connection and communicate the collected information to the network over the first connection. In some embodiments, the information includes a base station identifier, an MCC, an MNC, the cellular RAT and a cellular information age indicating the time since the information about the second connection was collected by the UE.

    Abstract: A station that performs methods related to emergency calls. In one example, the station determines that a first connection to a cellular network is unavailable, the client station being associated with a home network having a home Public-Safety Answering Point (PSAP), the station disposed at a location outside the home network, the location having a remote PSAP. The station determines a second connection to a WiFi network is available, establishes the second connection to the WiFi network and performs an emergency call over the WiFi network. The emergency call being routed to the remote PSAP associated with the location. In another example, the station determines it is capable of performing an emergency call over a cellular network, receives a request to perform an emergency call, determines whether a circuit switched radio access technology (CS-RAT) is available and performs the emergency call over a WiFi network when the CS-RAT is unavailable.

    Abstract: A user identity module (UIM) is incorporated in user equipment such as a mobile phone or mobile device. The UIM is configured to provision itself while roaming away from a home network as follows. The UIM may: send to the UE a request for information identifying a current radio access technology (RAT) that the UE is camped on; receive the current RAT information from the UE; send to the UE a request for network location information, where the network location information identifies a network in which the UE is currently camped; receive the network location information from the UE; generate an access point name (APN) using the current RAT information and the network location information; and open a channel through the network to a remote agent (e.g., a provisioning server) using the access point name.
