  • Publication number: 20250106749
    Abstract: A control function module of a mobile network receives, from a user terminal that has accessed the mobile network, a request to communicate with a data processing device connected to an external network outside the mobile network. The control function module determines whether or not a user of the user terminal is a registered user. In a case where a user of the user terminal is a registered user, the control function module transmits information used to establish communication between a communication device in the mobile network and the data processing device to an external network control device that controls the external network.

  • Patent number: 12081426
    Abstract: A stream information setting unit sets, with respect to a plurality of information collection object apparatuses, either a first transmission setting of a first data transmission of which a transmission cycle is designated or a second transmission setting of a second data transmission which uses a predetermined transmission cycle. A telemetry data receiving unit receives data from the information collection object apparatuses by the first data transmission executed according to the first transmission setting and the second data transmission executed according to the second transmission setting. A measuring unit measures a transmission time of data by the first data transmission. A comparing unit determines whether or not the transmission time measured by the measuring unit exceeds the designated transmission cycle. A cycle changing unit extends a transmission cycle of the second data transmission when the comparing unit determines that the transmission time exceeds the transmission cycle.
