摘要： PROBLEM TO BE SOLVED: To prolong a waiting time equally to that of a single-line mobile terminal since the single-line mobile terminal does not comprise a key lamp, so that a battery is not consumed thereby but current consumption of a multi-line mobile terminal at the time of traffic congestion is increased, becomes four times approximately, for example, by lighting a plurality of key lamps, and battery consumption is large, so that the waiting time is reduced to 1/4, approximately.
SOLUTION: A base power saving unit (10) is provided for exchanging, with a multi-line mobile terminal (MLP), the situation of using a plurality of telephone lines as power saving information when performing wireless communication with the multi-line mobile terminal via an access point (AP) connected to a private communication network (LAN) while accommodating a plurality of telephone lines (2) and in the multi-line mobile terminal, key lamps corresponding to the plurality of telephone lines, for displaying one idle line among the plurality of telephone lines so as to make it selectable are turned off in a non-communicating state according to the power saving information.

摘要翻译：要解决的问题：由于单线移动终端不包括钥匙灯，因此等待时间等于单线移动终端的等待时间，使得电池不被消耗，因此电流消耗交通拥堵时的多行移动终端增加，例如通过点亮多个按键灯而成为四倍左右，电池消耗量大，使得等待时间大致减少到1/4。解决方案：提供一种基本功率节省单元（10），用于与多线路移动终端（MLP）交换使用多条电话线路作为省电信息的情况，当与多线路移动终端（MLP）进行无线通信时，线路移动终端经由连接到专用通信网络（LAN）的接入点（AP），同时容纳多条电话线（2），并且在多行移动终端中，与多条电话线相对应的键灯，用于显示根据省电信息，在多个电话线中使得可选择的一条空闲线路处于非通信状态。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problem that an interference between slots is generated because a system A and the system B are not in a synchronous relationship when the service area B of a base station belonging to another system B is overlapped in the service area A covered by the synchronous control base station of the system A and a plurality of the subsidiary base stations. SOLUTION: One of a plurality of the base stations is used as the synchronous control base station, and a reference timing is transmitted to other base stations by radio. Each base station oscillates free-running clocks, and has phase measuring sections 17 measuring deviations among the reference timing received by radio and the transmission timings of control channels and phase adjusting sections 18 phase-adjusting the deviations so as to be minimized and other base stations are synchronized with the synchronous control base station. The synchronous control base station measures the deviations with the base stations belonging to the system B when the interferences are generated among another system B and the slots, the phase of the reference timing is adjusted so that the deviations are minimized and the interferences among the slots are avoided.
