    Abstract: An approach to managing stored-value data objects, such as electronic tickets, comprises secure systems and procedures for ticket issuing, storage, and redemption. With these systems and procedures in place, stored-value data objects may be securely transferred to remote systems, such as a user's personal electronic device, for subsequent secure redemption, thus allowing the user to gain access to the desired goods or service upon redeeming the data object. Techniques provide secure delivery of the requested data object to the requesting device, and provide secure redemption and disposal of the data object. Ticket issuing systems may be Internet-accessible systems, and users may purchase and redeem tickets using mobile terminals or other devices adapted for wireless communication. Standardized WPKI and Internet access procedures may be employed in ticket issuance and redemption. Techniques further provide temporary and rapid verification data objects useful where rapid ticket verification is essential, such as mass transit systems.

    Abstract: A satellite communications system includes a satellite that is configured to wirelessly communicate with radioterminals in a satellite coverage area over a satellite frequency band, and an ancillary terrestrial component that is configured to wirelessly communicate with radioterminals in the satellite coverage area over at least some of the satellite frequency band, to thereby terrestrially reuse at least some of the satellite frequency band. Wireless communications with a radioterminal are handed over from the ancillary terrestrial component to the satellite if the radioterminal transmit power exceeds a threshold, and a received satellite signal quality exceeds a threshold, even though the radioterminal is able to wirelessly communicate with the ancillary terrestrial component. Downlink wireless radiation that is received at the radioterminal from a satellite may be monitored to determine potential interference created by the uplink radiation of the radioterminal due to the terrestrial reuse of at least some of the satellite frequency band.

    Abstract: Communications between a terminal and a terrestrial base station are established. The terrestrial base station receives a request to monitor a satellite base station from the terminal. The terrestrial base station grants the request and receives monitoring information for the satellite base station corresponding to the request. Granting of the request may include suspending transmission from the terrestrial base station to the terminal for a period of time sufficient to allow the terminal to request the monitoring information from the satellite base station and receiving monitoring information may include receiving the requested monitoring information at the terrestrial base station via a communications path not including the terminal. Suspending transmission from the terrestrial base station to the terminal may be followed by resuming transmission to the terminal before receiving the monitoring information at the terrestrial base station. The communications path not including the terminal may include a terrestrial Access Service Network Gateway serving the terrestrial base station and a satellite Access Service Network Gateway serving the satellite base station. Handover techniques are also described.

    Abstract: Methods are provided to operate a communications system including a satellite and a satellite gateway. In particular, a feeder link may be provided between the satellite and the satellite gateway over a feeder link frequency band for communication of information between the satellite gateway and the satellite. A service link may be provided between the satellite and at least one radioterminal in a coverage area of the satellite over a service link frequency band.
