Summary:PROBLEM TO BE SOLVED: To minimize degradation of service quality of a wireless terminal due to imposition of an improper NAS back-off time.SOLUTION: A controller (300) includes a control section (301) and a notice section (302). The control section (301) is configured to determine the timer value of a NAS back-off timer (110), arranged in a wireless terminal (100) for suppressing transmission of a NAS request message, between a lower limit time and an upper limit time. The notice section (302) is configured to notify the wireless terminal (100) of the NAS back-off timer value thus determined. Furthermore, at least one of the lower limit time and upper limit time of the NAS back-off is determined depending on at least one of the communication interval and communication duration time of the wireless terminal (100). 【課題】適切でないNASバックオフ時間を課すことに起因した無線端末のサービス品質の低下を抑制する。【解決手段】制御装置(300)は、制御部(301)および通知部(302)を含む。前記制御部(301)は、NAS要求メッセージの送信抑止のために無線端末(100)に配置されるNASバックオフタイマ(110)のタイマ値を下限時間及び上限時間の間で決定するよう構成されている。通知部(302)は、決定されたNASバックオフタイマタイマ値を無線端末(100)に通知するよう構成されている。さらに、NASバックオフの下限時間及び上限時間の少なくとも一方は、無線端末(100)の通信間隔及び通信継続時間の少なくとも一方に応じて定められている。【選択図】図4
