Abstract: An object of the present disclosure is to prevent a decrease in a window size, thereby reducing a quality degradation time due to handover processing.
The present disclosure is a communication system in which a communication terminal communicates with an arbitrary communication device according to an allocated window size, in which the communication system saves a window size before handover or a window size determined based on the window size when the communication terminal performs the handover, and determines window size after the handover based on the saved window size.

Abstract: An object of the present disclosure is to enable network control to be executable that does not deteriorate experience quality of a user even in a case where the user uses a terminal.
A communication processing device according to the present disclosure,



when detecting occurrence of network control that is different from a user controlled application, collects user information indicating a state of a user that uses a terminal, predicts an experience quality change of the user in a case of executing the network control using the user information obtained by the collection, and executes the network control on the basis of an experience quality change amount of the user obtained by the prediction.

Abstract: An object of the present invention is to provide a communication system and a communication method that can avoid network congestion using a simple approach. The communication system of the present invention is characterized in that a time distribution server that transmits time information to terminals distributes a time different from the standard time for each terminal, and the terminal performs communication on the basis of the distributed time, and further characterized in that, for a time synchronizing packet transmitted from a time distribution server on the Internet to a terminal, a node or the like in the middle of the path performs transfer control or rewrites the packet, thereby causing the terminal to recognize a different time, and the terminal performs communication on the basis of the time.
