摘要： PROBLEM TO BE SOLVED: To easily detect a fault of a base station that is less likely or does not occur when there is little or no traffic.SOLUTION: A first base station, which is a diagnosis target, instructs attenuation of a transmission power toward a prescribed second base station. The second base station attenuates the transmission power in accordance with the instruction from the first base station to thereby cause the terminals connected to itself for calling to switch to the first base station. The first base station performs diagnosis of the first base station by the process for switching connection for call from the second base station to the first base station.
摘要翻译：要解决的问题：为了容易地检测到在很少或没有业务量时不太可能或不发生的基站的故障。解决方案：作为诊断对象的第一基站指示朝向规定的第二基站的发送功率的衰减。第二基站根据来自第一基站的指令衰减发送功率，从而使连接到其自身的终端进行呼叫切换到第一基站。第一基站通过用于从第二基站切换到第一基站的呼叫连接的处理来执行第一基站的诊断。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To collect the latest safety information in a short time without generating congestion in a network when communication between a safety confirmation server on a center side for collecting the safety information from a portable radio terminal and radio base stations recovers after the communication between both of them becomes impossible during a disaster occurs.SOLUTION: When communication with a safety confirmation server 103 becomes impossible due to the occurrence of a disaster, each radio base station 101 autonomously collects safety information from a portable radio terminal 102 controlled by the own station. At a point of time when the communication with the safety confirmation server 103 recovers, each radio base station 101 consolidates the safety information which has been collected up to the time and collectively transmits the consolidated safety information to the safety confirmation server 103.
摘要翻译：要解决的问题：为了收集来自便携式无线电终端的安全信息和无线电基站恢复的中心侧的安全确认服务器之间的通信，在短时间内收集最新的安全信息而不产生网络拥塞在灾难发生之后，两者之间的通信变得不可能。解决方案：由于发生灾难时与安全确认服务器103的通信变得不可能，各无线基站101自主地从由本台控制的便携式无线终端102收集安全信息。在与安全确认服务器103的通信恢复的时刻，各个无线基站101将已经收集的安全信息合并到一起，并将合并的安全信息统一发送到安全确认服务器103。版权所有（C）2013，JPO＆INPIT
