  • Patent number: 7047010
    Abstract: A system and method is disclosed for providing rescue channel communications between base stations in a wireless communication system. The invention comprises a source base station that is capable of sending messages to a rescue base station to cause the rescue base station to establish a rescue channel for a mobile station that has lost its traffic channel. The messages for establishing rescue channels communications between the base stations comprise Internetwork Operating System (IOS) messages that have been modified to add rescue channel indicator information. In an alternate advantageous embodiment of the invention, specially designed rescue channel activation messages and rescue channel activation acknowledgment messages are used to establish a rescue channel for the mobile station.

  • Patent number: 7043204
    Abstract: A method and apparatus for effective through-the-earth communication involves a signal input device connected to a transmitter operating at a predetermined frequency sufficiently low to effectively penetrate useful distances through-the earth, and having an analog to digital converter receiving the signal input and passing the signal input to a data compression circuit that is connected to an encoding processor, the encoding processor output being provided to a digital to analog converter. An amplifier receives the analog output from the digital to analog converter for amplifying said analog output and outputting said analog output to an antenna. A receiver having an antenna receives the analog output passes the analog signal to a band pass filter whose output is connected to an analog to digital converter that provides a digital signal to a decoding processor whose output is connected to an data decompressor, the data decompressor providing a decompressed digital signal to a digital to analog converter.

  • Patent number: 7043230
    Abstract: A system for authenticating and/or authorizing users of a service includes one communication interface with an access communication channel and another communication interface with a confirmation communication channel. Requests for a user to access a service are received over the access communication channel, and confirmation codes for the user are received over a trusted confirmation channel, such as an SMS text messaging system. Confirmation codes may be received from the user requesting access to the service or by a third party acting as a gatekeeper to the service. The system tests the validity of received confirmation codes, and enables the user to access the service if a valid confirmation code is received.

  • Patent number: 7039440
    Abstract: A method, computer program product and system that may be used to limit the funds that are available through the use of a business transaction card by having a business transaction card first place a request for an increase of the available funds. A wireless device is sensed within a proximity to a terminal that supports wireless communication and communication between the wireless device and the terminal is established for transferring an identification code from the wireless device to the terminal. The terminal is communicatively connected to a server and the terminal automatically transfers the identification code from the terminal to the server. The server matches the identification code with an account number of the business transaction card and, if authorization exists, automatically increases the funds available balance of the business transaction card.

  • Patent number: 7013128
    Abstract: A portable terminal includes a function to detect its own location. The owner of such terminal registers in advance an area in which he expects to be for a given time slot as conditions for operation. The portable terminal verifies its location with respect to the operation conditions set by the owner, and where it is determined that the operation conditions are not met, the portable terminal disables itself, prohibiting its use. Where a pre-registered password is subsequently input, the portable terminal cancels this prohibition. Consequently, if the owner loses the portable terminal while away from home or the office, for example, a third party cannot operate the portable terminal, and moreover, unless the owner-registered password is input, the prohibition is not cancelled, thereby preventing disclosure of the data and other information stored in the portable terminal.

  • Patent number: 6999759
    Abstract: A communication system, upon receiving an instruction to transfer deferrable data, determines whether an air interface is congested and, when the air interface is congested, defers a transfer of the deferrable data or transfers the deferrable, lower priority data as higher priority data. When, during a transfer of deferrable data, the system determines that the air interface is congested, the system may terminate the call and save a state of a partially completed deferred data transfer. Subsequent to the termination of the call, the system establishes another data connection over the air interface and transfers any remaining, not yet transferred deferrable data. In order to discourage subscribers from transferring higher priority data as lower priority data, the system may further restrict a transfer of lower priority data to designated time periods while allowing a transfer of higher priority data during the designated time periods and other time periods.
