  • Authentication in a packet data system
    Patent number: 6229806
    Abstract: A communication system in which a user device (10) generates authentication information (32) unique to the user device and provides a data packet (35) including this authentication information to an infrastructure part which is a gateway (14) or a host (16). The packet also contains a host identifier (36) or time dependent information (202). This is used at the gateway (14) or the host (16) to authenticate the packet.

  • Data communications system with session control
    Patent number: 6092111
    Abstract: A method of operation of a data communications system (5) with session control having a data communications network (10) and at least a first communications device (1), a second communications device (2) and a third commnunications device (3) in communications with the data communications network (10). The data communications network (10) identifies a fault status change in communications with the first communications device (1), generates a session control command (6) with an identification number (7) attached responsive to identifying the fault status change and sending the session control command (6) to at least the second and the third communications devices (2 and 3). At least at the second communications device (2), the second communications device (2) receives the session control command (6), deter-mines from the identification number (7) whether the second communications device (2) is affected by the fault status change and selectively performs a session control action in response thereto.

  • Method and apparatus for avoiding desensitization of a radio frequency receiver
    Patent number: 5765113
    Abstract: A subscriber terminal (104) suitable for operation in a wireless communications system (100) arranged and constructed to provide data communications between the infrastructure (111) and the subscriber terminal, includes a portable computing device (105) operating in a operating state and a radio frequency receiver (201) operatively coupled to the portable computing device, the radio frequency receiver arranged to detect a radio frequency interference corresponding to an operating environment, and to execute a corrective action that corresponds to the radio frequency interference. A corresponding method of avoiding desensitization of the radio frequency receiver includes detecting, at the RF receiver, a radio frequency interference that corresponds to an operating environment to provide an interference indication; determining, responsive to the interference indication, a corrective action for the RF receiver; and executing the corrective action for the RF receiver.
