20080307231 | Secure Handling of Stored-Value Data Objects - 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. | 12-11-2008 |
20090137203 | SATELLITE COMMUNICATIONS SYSTEMS AND METHODS USING RADIOTELEPHONE LOCATION-BASED BEAMFORMING - A processor for use in a satellite communications system includes a selector that is configured to select a subset of a plurality of spatially diverse satellite signals based upon a location of a radioterminal. The processor further includes a signal processor that is configured to detect a return-link transmission from the radioterminal responsive to the selected subset of the spatially diverse satellite signals. The respective spatially diverse satellite signals may include respective signals corresponding to respective antenna elements of a satellite. The selector and the signal processor may be ground based. | 05-28-2009 |
20090156154 | Satellite-band spectrum utilization using receiver filters to reduce interference - A first and/or a second communications system may provide communications service over a geographic area. A method of operating the first and/or the second communications systems may include generating a measure of aggregate interference reaching a satellite of the second communications system substantially from devices of the first communications system. The measure of aggregate interference reaching the satellite of the second communications system may be transmitted to an element of the first communications system. | 06-18-2009 |
20100210209 | RADIOTERMINALS AND OPERATING METHODS THAT RECEIVE MULTIPLE MEASURES OF INFORMATION FROM MULTIPLE SOURCES - A radioterminal includes a receiver that is configured to receive information from a base station by receiving a first measure of the information from the base station and a second measure of the information from a second device. The second device receives a measure of the information from the base station, responsively generates the second measure of the information and transmits the second measure of the information to the radioterminal over a short-range wireless link. Related methods are also described. | 08-19-2010 |
20100210262 | RADIOTERMINAL SYSTEM SERVERS AND METHODS - A radioterminal system includes a server that contains a listing of satellite spot beams and registration information for radioterminals. The listing of satellite spot beams includes an association of base stations with each satellite spot beam of the listing of satellite spot beams. Related methods are also provided. | 08-19-2010 |
20110077002 | SYSTEMS AND METHODS FOR MOBILITY MANAGEMENT IN OVERLAID MOBILE COMMUNICATIONS SYSTEMS - Communications of a mobile station with a satellite mobile communications system and a terrestrial mobile communications system are coordinated. The mobile station is registered with the terrestrial mobile communications system and, responsive to the registration of the mobile station with the terrestrial mobile communications system, the mobile station is concurrently registered with the satellite mobile communications system. The concurrent registration may include implicitly registering the mobile station with the satellite mobile communications system, e.g., by storing information identifying the mobile station may be stored in a location register of the satellite mobile communications system responsive to the registration of the mobile station with the terrestrial mobile communications system, and maintaining synchronization between the two registrations. Authentication tokens may be pre-generated for quick re-registration with a satellite mobile communications system. | 03-31-2011 |
20110212694 | Satellite-Band Spectrum Utilization For Reduced Or Minimum Interference - A first and/or a second communications system may provide communications service over a geographic area. A method of operating the first and/or the second communications systems may include generating a measure of aggregate interference reaching a satellite of the second communications system substantially from devices of the first communications system. The measure of aggregate interference reaching the satellite of the second communications system may be transmitted to an element of the first communications system. | 09-01-2011 |
