  • Publication number: 20220014550
    Abstract: An object is to provide a monitor device capable of reducing threat of DoS attacks on a mobile network. A monitor device (10) according to the present invention includes a signal monitor unit (11) for estimating a specific base station communicating with a communication terminal (30) attacking a mobile network according to the number of times an ATTACH procedure is rejected, in which the ATTACH procedure is for registering information about a communication terminal (30) communicating with a base station (20) in a communication device (40) located in the mobile network, and a base station control unit (12) for causing the specific base station to determine whether to execute the ATTACH procedure related to a communication terminal served by the specific base station according to communication terminal identification information set in a signal transmitted from the communication terminal served by the specific base station.

  • Patent number: 8230036
    Abstract: The server of a communication system determines a communication growth level that is the level of growth of communication between one user and another user based on the cumulative count of mail send/receive events, and stores the determined growth level in the communication growth level Data Base. When the server receives a profile view request to view the profile of user A from the terminal of user B, the server determines the range of profile information to be opened for user B out of the profile of user A, based on the communication growth level of the pair of user A and user B stored in the communication growth level Data Base.

  • Publication number: 20060057846
    Abstract: Disclosed are a composition for a sanitary ware body for use in slip casting, possessing excellent long-term storage stability, transportability and slurry regeneration, a production process of the same, and a production process of a sanitary ware using the composition for a sanitary ware body. This composition for a sanitary ware body comprises agglomerate of a raw material powder for said sanitary ware body and has a water content of 0 (zero) to 25% by weight and a 50% average particle diameter of 1 to 15 ?m on a number basis of the powder. A slurry of a raw material for a sanitary ware body for use in slip casting can be prepared by adding water to the composition for a sanitary ware body and stirring the mixture.
