    摘要： A method and mobile transceiver having advanced network selection are provided. In accordance with one embodiment, there is provided a method of operating a mobile transceiver, comprising: determining whether a current location of the mobile transceiver corresponds to a waypoint in a pre-programmed travel itinerary, the travel itinerary being stored in a memory of the mobile transceiver and defining a plurality of waypoints along a planned route, each of the waypoints defining a location, the waypoints including an origin endpoint, a destination endpoint and intermediate locations between the origin endpoint and destination endpoint; in response to a determination that the current location corresponds to a waypoint in the travel itinerary: activating a predetermined wireless transceiver from a plurality of wireless transceivers from a low power mode in accordance with the waypoint corresponding to the current location or a wake-up event.

    摘要： A mobile wireless communications device may communicate with a terminal including a first NFC device, the terminal being capable of receiving data from a provisioning server. The mobile wireless communications device may include a housing, a wireless transceiver carried by the housing, a second NFC device carried by the housing, a memory carried by the housing, a display carried by the housing, and a processor carried by the housing and coupled to the wireless transceiver, the second NFC device, the memory, and the display. The processor may be configured to implement a digital wallet including user cards, receive from the terminal, via the second NFC device, a blank user card including user data fields, and fill the user data fields of the blank user card to define a completed user card and send the completed user card to the provisioning server.

    摘要： A service type announcement element indicates one or more service types offered by an access point (AP) that supports station a wireless network. The service type announcement element is generated by the AP and included in a beacon frame or in a probe response frame. The beacon frame or the probe response frame is transmitted by the AP and received by a mobile device prior to the mobile device being associated with the AP. The mobile device makes a determination whether any of the one or more service types can assist with an operation of an application on the mobile device and implements a network selection algorithm based on the determination.
