  • Publication number: 20010004593
    Abstract: A mobile station can be selectively coupled to two or more networks. By maintaining an address translation table and introducing communication between the switching control units within the multiple networks, it is possible to provide notification to the mobile station of the existence of a communication request from a first network while the mobile station coupled to the second network.
    Type: Application

  • Patent number: 6188899
    Abstract: A method and system automatically activates a mobile station in a wireless communications network. The system includes an over the air activation function (OTAF) processor in the network that initiates an activation process in response to receiving a registration message from a mobile switching center serving the mobile station requesting the activation. Each mobile station has a unit of information stored into it at the time of its manufacture to enable it to request over the air activation. That unit of information is either the network routing address of the OTAF processor, or alternately, it is a value that is translatable into that address, either an OTAF ID number that is the same value for every mobile station or it is a sequentially serialized dummy value for the mobile identification number (a dummy MIN). When the mobile station is turned on for the first time in the network, it requests activation over the air by transmitting to the local mobile switching center a registration order.

  • Patent number: 6039624
    Abstract: A portion of the bits within an assigned Temporary Mobile Station Identification (TMSI) number are encoded based upon a subscriber's group classifications (i.e., classifications based on the user's characteristics, such as subscriber services and affiliation). When a mobile station user requests service in a visiting location, the user's service profile is accessed to determine the user's group classifications (if any). The mobile station is assigned a TMSI number according to the user's accessed service profile and a portion of bits associated with the TMSI number are encoded based on the identifiable user group classification. The length of the assigned TMSI number may be adjusted depending upon the particular application to maximize the number of TMSI numbers that may be transmitted in a single paging slot.

  • Patent number: 5946615
    Abstract: The present invention is a system and method of providing the information necessary for geographically-based mobile services by translating public geographic information to corresponding mobile network structure. When an indication of a geographic area is received, the indication is translated to an indication of a portion of the mobile network corresponding to the geographic area and an indication of the service is transmitted to the indicated portion of the mobile network. In a preferred embodiment, a broadcast message is transmitted over a mobile network to a plurality of mobile stations within a geographic area. When the system receives a message to be broadcast and an indication of the geographic area of the broadcast, the indication of the geographic area is translated to an indication of a portion of the mobile network corresponding to the geographic area. The message is then transmitted to the indicated portion of the mobile network.

  • Patent number: 5875395
    Abstract: A system and method for preventing unauthorized use of a remotely operated system, by using a sophisticated bi-directional verification schemes. The bi-directional verification schemes are based on random challenge and response between a mobile station and a cellular network. The cellular network discriminates between "pirate" mobile stations and mobile stations authorized to use the cellular network. The security afforded by bi-directional verification is applied to a system and method for use in conjunction with remotely operated systems, including one or more pieces of application equipment or a home automation system.
