Abstract: A gateway transmits a communication switch request to a communication control unit by HTTP communication. The communication switch request serves to switch connection with a data center from HTTP communication to WebSocket communication. The communication control unit, when the communication switch request is received from the gateway, switches communication with the gateway device to WebSocket communication. A mobile terminal transmits a management execution request requesting execution of a management process of a PLC, to the data center. The communication control unit transmits a session establishing request requesting establishment of a session with the PLC, to the gateway by WebSocket communication based on the received management execution request.

Abstract: A simulation apparatus (10) calculates, as an appropriate value, a sensor value at which productivity increases, from a sensor value detected with a sensor disposed in an automation system (20) and productivity of the automation system (20) at a time when the sensor value is detected. While sequentially changing setting, the simulation apparatus (10) executes a simulation of an operation of the automation system (20) and calculates a predicted value of the sensor value for each setting. The simulation apparatus (10) identifies the setting in a case where the predicted value is close to the appropriate value.

The retriever retrieves candidates of sub-networks that can be employed by the radio communication terminal on the basis of the location information on the radio communication terminal. The radio communication terminal selects a sub-network for its use among from the candidates and establishes an environment for communication with the sub-network.

Abstract: In a multiservice wireless communication system according to the present invention, a location manager 47 of a multiservice terminal 140 detects its own position with a GPS receiver interface 49. The location manager sends the detected positional information to a management server 110 via a common-signaling wireless network base station 100 in which respective multiple service zones serviced by multiple wireless systems overlap in a common-signaling wireless zone and acquires information on available wireless systems as a response to that. A network selecting section 44 selects a wireless system that most matches selecting conditions from the acquired available wireless systems and performs communication via the interfaces 40 and 41 that operate the selected wireless system.

Abstract: In a system where a plurality of mobile terminals shares a data of the server, upon issuing an update request data of server from the mobile terminals, without depending on the stability of the communication method used by the mobile terminals, a fair data updating becomes possible which only relies on an issuing order of the update request. In the present system, the clock module is provided to all the mobile terminals and the server having a synchronized time. The mobile terminal adds the update request issuing time obtained from the timing module to the update request data upon issuing the update request data, and the update request data is repeatedly sent until the server receives it. During the repeated transmission, an issuing time attached to the update request is identical to the original issuing time, and the server processes the data update request received within the update request reception period in an order of the issuing time.
