    • A wireless communication system including a wireless terminal, a plurality of base stations and a call processing control unit is disclosed. The wireless terminal, upon reception of the notification information from any of the base stations, judges whether the area included in the notification information is contained in the location registration area list stored in a storage unit, and in the case where the particular area is not so contained, sends a location registration request to the call processing control unit. On the other hand, the call processing control unit creates a new location registration area list based on the area included in the notification information and the neighboring areas, and sends the location registration area list to the wireless terminal.

    • In a case where reception power in a radio access point is high by external noise, the normalcy of the radio access point is tested. In order to judge the normalcy of the radio characteristic of the radio access point, a test is performed through the calling connection between a testing access terminal in the radio access point and a predetermined device. An RSSI is measured before and after the transmission of a test signal. When the RSSI exceeds a threshold value, the path loss of a reverse link connected from the radio access point to the testing access terminal is increased by an attenuator. Then, reception power in the testing access terminal decreases. Thus, initial transmission power in accordance with the reception power from the testing access terminal is raised and the calling connection of the testing access terminal can be performed even under the external noise.
    • 在无线接入点的接收功率由外部噪声高的情况下,对无线接入点的正常状态进行测试。 为了判断无线接入点的无线特性的正常状态,通过无线接入点的测试接入终端与规定的设备之间的呼叫连接进行测试。 在传输测试信号之前和之后测量RSSI。 当RSSI超过阈值时,由无线接入点连接到测试接入终端的反向链路的路径损耗由衰减器增加。 然后,测试接入终端的接收功率减小。 因此,提高了来自测试接入终端的接收功率的初始发送功率,即使在外部噪声下也能够进行测试接入终端的呼叫连接。
