摘要

住宅无绳电话(PCT)系统通过现有的PBX(专用交换分支)和/或单个控制器或控制器网络提供对PSTN(公共交换电话网)用户线路的完整功能访问。该系统使呼叫者能够直接拨打电话,与移动中的管理人员以及在有线电话无法到达的地方工作的工程师和技术人员联系,从而增强了企业通信。该系统为办公室、酒店、医院、建筑维修服务、百货公司、购物中心、交易会等提供类似的好处。基站配置具有位置注册和切换功能的微蜂窝结构,这将使系统规划者能够经济地定制系统,以满足交通密度的不同需求,并消除建筑结构、墙壁等的阴影效应。描述了该系统的特点,包括在微蜂窝(或皮蜂窝)结构中使用动态频率分配和灵活的基站布置(不规则位置),以确保用户友好的操作,充分扩展系统灵活性,并在高密度交通区域内显著增加交通容量。

Design features of a premises cordless telephone system
The premises cordless telephone (PCT) system provides a full function access to PSTN (public switched telephone network) subscriber lines via an existing PBX (private branch exchange) and/or a single controller or a network of controllers. The system enhances corporate communications by giving callers direct dial-through access to executives on the move and engineers and technicians working out of reach of wired telephones. The system offers similar benefits for offices, hotels, hospitals, building maintenance services, department stores, shopping malls, trade fairs, etc. Base stations configure the microcell structures with location registration and handoff features which will enable system planners to tailor the system economically to the diverse needs of traffic density and to eliminate the shadowing effects of building structures, walls, etc. The system features are described, including uses of the dynamic frequency assignment and flexible base station arrangement (irregularly located) within a microcell (or picocell) structure to ensure user-friendly operations, full extension of system flexibility, and significant increase in the traffic capacity within a highly dense traffic area.<>
