Abstract: A wireless parameter control device comprises: a serving cell prediction unit (11) which predicts a wireless cell which is a connection destination of a first wireless terminal within a first wireless cell upon assuming that an offset value which is added to the wireless quality which the first wireless terminal measures for each wireless cell is changed to a prescribed candidate value; a communication speed index prediction unit (12) which predicts a communication speed index of the first wireless terminal upon assuming that the offset value is changed to the prescribed candidate value and/or a communication speed index of a second wireless terminal within a second wireless cell which is present in the periphery of the first wireless cell; and a coverage control unit (13) which, on the basis of the result of the prediction of the communication speed index, controls the coverage of the first wireless cell and/or the coverage of the second wireless cell.

Abstract: A server switching decision unit decides whether to switch a server that provides a service to a service-utilizing terminal that receives the service from the server. In a case in which the server switching decision unit makes a decision to switch the server, the server decision unit decides a server of a switching destination from among a plurality of servers that are able to provide the service to the service-utilizing terminal in consideration of an allowable delay satisfaction duration indicating a length of time during which the service can be provided to the service-utilizing terminal with a delay time within an allowable delay time.
