  • Patent number: 5752188
    Abstract: A system and method is provided for controlling the signalling between the subscriber of a mobile station and an external service node such as a message center. The control of the signalling is carried out by using unstructured supplementary service data (USSD) which is analyzed by a USSD handler of a home location register which invokes a transparent transfer to external service node (TTEN) application when the USSD does not correspond to a service defined within the home location register. The TTEN application establishes a dialog with the subscriber of the mobile station and the desired external service node by using USSD. This allows the subscriber of the mobile station to access all message services by sending one service code. Also, the operator is not busy while accessing the services and any incoming calls may be answered while accessing the services.

  • Patent number: 5642398
    Abstract: A comprehensive method for mobile station registration in a cellular communication system wherein registrations are made due to multiple stimulus. Registration can occur as a function of distance traveled since the previous registration. Registration can occur due to entering the coverage area of a base station assigned to a zone in which the mobile station has not recently registered. A registration timer can be used to ensure a minimum time between registrations. Registrations can occur at power up and at power down. The mobile station can be ordered to register by a transmission from a base station. Registration can occur due to parameter changes with in the mobile station. Registration may also occur through necessary communication with a base station which is not expressly directed to registration.

  • Patent number: 5633914
    Abstract: A method for foiling cellular telephone cloning by verifying subscribers of a cellular communications network is accomplished by having each subscriber provide a local telephone number, typically not their own, to the cellular telephone company and long distance carrier for each cellular telephone they own in order to verify legitimate subscribers. The verification telephone numbers provided by the subscribers are stored in respective databases and correspond to electronic serial numbers of subscriber telephones. Shortly after power-up of the cellular telephone, a subscriber either invokes an automatic dialer or manually dials the verification telephone number.

  • Patent number: 5623534
    Abstract: The system of the invention has particular application to a wide area network (WAN) where call routing information often changes in one local area network (LAN) (e.g. a switching system) while other LANs (e.g. cellular communication systems) are unaware of the changes. Because of the heavy flow of traffic in such networks, the minimization of administrative traffic data is desirable. The invention solves the need for constant updating and auditing of the LANs in the WAN. One LAN is considered the master LAN for a given parameter and contains an accurate directory of administrative data for that parameter. Each of the other LANs operate on the assumption that the administrative or directory information it contains is correct.

  • Patent number: 5619552
    Abstract: A method and an arrangement for subscriber location management among a group of radio networks comprising at least two radio networks (101, PMR1, PMR2) in which at least some of the subscribers (SBR1, SBR2, SBR3) may roam away from the home network and register in another radio network over the radio path. To enable centralized subscriber location management, the subscriber database (HLR) of one radio network (101) is arranged to maintain in a centralized manner the location data of all subscribers (SBR1) that have roamed outside their home networks and registered in another radio network (PMR2) at least with an accuracy of a radio network.

  • Patent number: 5615247
    Abstract: A security device for the protection of cargo transport containers for use in the cargo transport industry. Once activated, the device notifies a security company that a break-in has taken place through the use of a cellular phone network. The security device utilizes a pair of cables exposed to the outside of the cargo transport container. In use, the cables are threaded through the door handles of the cargo transport container. Once the cables are joined on the outside of the cargo transport container, the device is armed. The security device becomes secure once a security code is entered by a user. Once the security code is entered and the cables are connected, the cargo doors may not be opened unless done by an authorized person. Should the pair of cables become disconnected or cut during transport of the container, the device will transmit a high frequency signal to a security company via a cellular telephone network.

  • Patent number: 5615250
    Abstract: A portable telephone set includes a main section thereof, an IC card, and a battery pack, which are removably connected to each other. The battery pack has an L-shaped rib to provide a slot in which the IC card is inserted. When the IC card is inserted in the slot, a side surface of the IC card is brought into contact with a side surface of the battery pack to be held therein in a unified form. In the combined state, a hook section of the battery pack is engaged with an engaging section of the main section. When the battery pack is pushed downward, a depressed portion of the battery pack is engaged with a lock member of the main section so as to fixedly attach the battery pack onto the main section. The IC card is pushed by the battery pack to be brought into contact with a connector of the main section so as to establish a stable connection therebetween. There is provided a small-sized, low-cost portable telephone set having improved operability of IC card installation and removal.

  • Patent number: 5604787
    Abstract: A smart card (100) is equipped with an internal time-of-day clock and calendar (106). Between the smart card (100) and a subscriber unit (209, 300), into which it is inserted, there is a communication of the subscriber's identity and a negotiated agreement for how long the subscriber unit (209, 300) is to maintain the transferred identity. For that duration of time, the subscriber unit (209, 300) is enabled with the subscriber's identity, and the smart card is essentially "dumb," and therefore unusable until that duration has elapsed.
