Abstract: In a communication system in which a transmitter transmits data over a communication channel of a fixed bandwidth to a receiver, the method according to which the transmit data rate is continuously adjusted to a rate which is substantially equal to a short-term average data rate. The channel capacity and/or other characteristics of the system, is continuously adjusted, through changes in transmit power, symbol rate and modulation format, to a level at which the ratio of received signal energy per bit to noise spectral density (Eb/N0) at the receiver is close to but above its minimum acceptable level, thereby matching the channel capacity and/or other characteristics of the system to the traffic. The system has further attributes which adjust the transmit data rate responsive to conditions involving at least one of data traffic levels, power reserve emergency, thermal load and message priority.

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 mobile terminal is enabled to conduct an EMV transaction. A wireless access node in the EMV card-reader terminal is provided for connecting a mobile terminal to the card-reader terminal. An EMV-proxy module executing in the card-reader terminal facilitates communication between the mobile terminal and the card-reader terminal. The EMV-proxy module lets the mobile terminal function in essentially the same way as a regular EMV chip card with respect to the card-reader terminal. The card-reader terminal may then conduct EMV transactions on behalf of the mobile terminal without requiring new software and/or hardware at the EMV issuer. EMV data is stored in the mobile terminal in the form of secure dynamic data objects. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

Abstract: 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.

Abstract: A first radio signal is received via a first satellite reception path, for example, an antenna or spot beam, which serves a satellite cell. The received first radio signal includes a desired satellite uplink signal transmitted from a first source using a frequency assigned to the satellite cell and an interfering signal transmitted from at least one second source using the frequency assigned to the satellite cell. A second radio signal is received via a second satellite reception path, for example, via another antenna or spot beam of the system and/or via a satellite antenna beam of another system. The second radio signal includes a measure of the interfering signal. The first and second radio signals are processed to recover the desired satellite uplink signal.

Abstract: Data transfer efficiencies of a frequency division and/or time division multiple access (FDMA/TDMA) communication methods are improved over prior art methods by communicating over a channel group of a comunication system. A central station transmits to a number of terminals over a forward channel, and transmissions by at least one of the terminals to the central station occur over a return channel of the channel group. The improved methods include the step of transmitting by the at least one of the plurality of terminals at least one superframe to the central station at one of a plurality of data rates over one of a plurality of return channels using a corresponding one of a plurality of data frames having lengths responsive to the one of the plurality of data rates. The methods may also include the step of formatting said transmission superframe comprising a plurality of frames by removing network management information which is not time critical from substantially all of the plurality of frames.

Abstract: A method of communicating on at least one channel group of a communication system provides improved data transfer efficiencies over conventional systems by using discrete transfer rates. The channel group is includes at least one forward channel for channeling data transmitted from a central station to a plurality of terminals. At least one return channel is included for channeling transmissions by any of the plurality of terminals to the central station. Changes in the discrete data transfer rate are optionally accompanied by a change in a slot timing rate based on a frame transmission rate used over the forward channel. The method also allows the assignment of a predetermined number of return channel slots for a transmit frame for at least one combination of forward and return channels having prescribed forward and return data rates.
