Abstract

　本発明は、パス切替制御を早期に実施できるようにし、また、無線通信の通信効率低下を抑制できるようにしたもので、このために、無線端末（３０）と、当該無線端末（３０）と無線により通信する複数の無線基地局（２－１，２－２）と、前記無線端末（３０）との通信に用いるパスを第１の無線基地局（２－１）を介した第１のパスから第２の無線基地局（２－２）を介した第２のパスに変更する制御装置（１）とをそなえた無線通信システム（４０）において、前記制御装置（１）は、前記第１の無線基地局（２－１）での前記無線端末（３０）宛のデータの残存量を監視し、その監視結果に応じて前記第２のパスへの変更タイミングを制御する。
