    • 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。

    • In a conventional system, there is a possibility that human errors are generated in setting registration information because a maintenance engineer manually enters registration information into a session reference network controller which integrally controls access terminals and base stations. To improve the system, session reference network controller a session reference network controller stores the number of access terminals, N, in advance. And, when a “base distance” setting request is received from an access terminal via a base station, the session reference network controller or an OAM (Operation, Administration and Maintenance) server determines a base station, which is one of a plurality of controlled base stations and is Nth nearest from the base station that has transmitted the setting request, and sets the distance between the base station, which has transmitted the setting request, and the base station, which is Nth nearest, as the “base distance”.
    • 在常规系统中,由于维护工程师将注册信息手动输入到整体控制接入终端和基站的会话参考网络控制器中,因此在设置注册信息中存在人为错误的可能性。 为了改进系统,会话参考网络控制器一个会话参考网络控制器预先存储接入终端数量N。 而且,当经由基站从接入终端接收到“基本距离”设定请求时,会话参考网络控制器或OAM(Operation,Administration and Maintenance)服务器确定基站,其为多个被控制的 并且与已经发送设置请求的基站最近的Nth,并且将已经发送了设置请求的基站与第N个最近的基站之间的距离设置为“基本距离”。
