Title:
移動通信システムのリンク電力制御試験方法
Document Type and Number:
Japanese Patent JP4229974
Kind Code:
B2
Abstract:
A device for testing the link power control in a mobile communications system includes: a first device including an attenuator whose attenuation factor is controllable; a base station transmitting data through the attenuator; a mobile receiving the data transmitted from the base station through the attenuator; a first cable for connecting the transmission terminal of the base station to the input terminal of the attenuator; a second cable for connecting the output terminal of the attenuator to the reception terminal of the mobile; and a third cable for connecting the reception terminal of the base station to the transmission terminal of the mobile, the first device being for testing the forward link power control; and a second device including an attenuator whose attenuation factor is controllable; a mobile transmitting data through the attenuator; a base station receiving the data transmitted from the mobile through the attenuator; a fourth cable for connecting the transmission terminal of the mobile to the input terminal of the attenuator; a fifth cable for connecting the output terminal of the attenuator to the reception terminal of the base station; and a sixth cable for connecting the transmission terminal of the base station to the reception terminal of the mobile, the second device being for testing the reverse link power control.
