Description

对使用共享设备的建筑物内的宏服务小区 和微微服务小区提供蜂窝电话业务的方法和装置
发明背景
发明的技术领域
本发明一般关于蜂窝电话网内服务小区站点的规划和实施，更具体地关于提供建筑物内微微服务小区覆盖，以及从处于建筑物外的宏服务小区向使用共享设备的建筑物内提供扩展覆盖。
有关技术描述
蜂窝电话业务变得越来越普遍，用户希望在整个业务区内得到不受打断的覆盖。但是，用户常常会遇到，当他们进入无线电波传播受到物理障碍阻碍的盲点时，蜂窝电话业务中断的现象。这种业务中断的一个地点通常出现在建筑物内，在那里蜂窝电话覆盖或者质量不一，或者不存在。为了在建筑物内提供不受中断的蜂窝电话业务，蜂窝电话规划者在处于建筑物外的宏服务小区之外，还辅助一个处于建筑物内的微微服务小区。在设计微微服务小区时，蜂窝电话提供者通过分配单独一组无线频率而精心地产生与宏服务小区不同的微微服务小区。因此，进入建筑物之前使用蜂窝电话的蜂窝电话用户被处于建筑物外的宏服务小区服务。一旦进入建筑物，蜂窝电话呼叫从宏服务小区越区切换到微微服务小区，当蜂窝电话用户在建筑物内时受到微微服务小区的服务。
在某些情况下，例如机场以及高耸的办公建筑区，大量蜂窝电话用户试图同时使用系统，微微服务小区有很大的容量需求。在这些区域，蜂窝电话提供者需要增加容量以便保证满足增长的需求。因此，最好是将出现在建筑物外的蜂窝电话网的宏服务小区覆盖扩展到建筑物内，也由微微服务小区服务以满足峰值容量需求。此外，最好是通过共享微微服务小区所用的设备来将宏服务小区覆盖扩展到建筑物内。
发明内容
本发明将蜂窝电话业务从处于建筑物外的宏服务小区向建筑物内扩展，同时通过与处于建筑物内的微微服务小区关联的单独射频提供蜂窝电话业务。一组合并器(合并射频传输)和分解器(复制射频传输)允许使用微微服务小区天线用于微微服务小区和宏服务小区覆盖。在本发明的一个实施例中，用于对宏服务小区提供蜂窝电话业务的收发机和用于对微微服务小区提供蜂窝电话业务的收发机共享公共的基站和到蜂窝电话网的通信链路。在本发明的第二实施例中，在与宏服务小区关联的频率上发射的收发机只在建筑物内提供蜂窝电话业务并通过中继器与处于远端的分配给宏服务小区的基站通信。
附图的简要描述
为了更完整地理解本发明，结合所附的附图参考如下详细描述，其中：
图1描述了包含处于宏服务小区业务区内的微微服务小区的建筑物；
图2是说明本发明第一实施例的发射路径的蜂窝通信系统框图；
图3是说明本发明第一实施例的接收路径的蜂窝通信系统框图；
图4是说明本发明第二实施例的发射路径的蜂窝通信系统框图；
图5是说明本发明第二实施例的接收路径的蜂窝通信系统框图；
发明的详细描述
现在参考图1，其中说明了处于蜂窝电话网140的宏服务小区110内的建筑物100。宏服务小区110受基站120服务，基站120连接到外部天线130并进一步通过通信链路145连接到蜂窝电话网140。处于建筑物100内的是微微服务小区业务区150。微微服务小区受基站120和多个处于建筑物100内的天线160服务。本发明利用相同的多个天线160，将外部通过天线130提供的宏服务小区110覆盖扩展到微微服务小区业务区150。
现在另外参考图2，其中结合蜂窝系统框图，说明了本发明第一实施例的发射路径。第一组收发机200，包括一个或多个收发机205，向宏服务小区业务区110提供蜂窝电话业务。第一收发机205组200通过发送复接器170和通信链路145连接到蜂窝电话网140。第二组收发机210，由一个或多个收发机205组成，向处于建筑物100内的微微服务小区150提供蜂窝电话业务。第二收发机205组210通过发送复接器170和通信链路145连接到蜂窝电话网140。第一收发机205组200的输出220作为输入提供给合并器230。合并器230合并发射机输出信号220，产生单个合并输出信号240。合并输出信号240作为输入提供给分解器250，分解器250复制合并输出信号240。合并输出信号240的第一份拷贝260提供给处于建筑物100外的天线130并向宏服务小区业务区110提供蜂窝电话业务。合并输出信号240的第二份拷贝270作为输入提供给第二合并器280。第二合并器280也有来自向微微服务小区150提供蜂窝电话业务的收发机205组210的输出信号290作为输入。合并器280将第一合并输出信号240的第二份拷贝270与发射机输出信号290合并，产生单个合并输出信号300。合并输出信号300连接到处于建筑物100内的多个天线160，在建筑物100内建立合并的微微服务小区150和宏服务小区110覆盖区。
当蜂窝电话在建筑物100外、宏服务小区110内操作时，它通过天线130从基站120接收蜂窝电话业务。当蜂窝电话在建筑物100内移动、而且从天线130发射的信号衰落时，蜂窝电话继续通过多个天线160从基站120接收传输。
现在另外参考图3，其中结合蜂窝系统框图，说明了本发明第一实施例的接收路径。第一组收发机200，包括一个或多个收发机205，通过发送复接器170和通信链路145连接到蜂窝电话网140。第一收发机205组200向宏服务小区业务区110提供蜂窝电话业务。第二组收发机210，由一个或多个收发机205组成，通过发送复接器170和通信链路145连接到蜂窝电话网140。第二收发机205组210向处于建筑物100内的微微服务小区150提供蜂窝电话业务。从处于宏服务小区业务区110内的蜂窝电话发射的信号被天线130接收并作为输入提供给合并器300。从处于建筑物100内的微微服务小区150中的蜂窝电话发射的信号由多个天线160接收并作为另一个输入提供给合并器305。合并器305将从天线130接收的信号与从多个天线160接收的信号合并，产生单一合并输出信号310。分解器320复制合并输出信号310，产生合并输出信号310的多个拷贝330。多个拷贝330作为输入提供给收发机205。
当蜂窝在建筑物100外、宏服务小区业务区110内操作时，它通过天线130从基站120接收蜂窝电话业务。当蜂窝电话在建筑物100内移动时，传输由多个天线160拾取，信号通过合并器305和分解器320被收发机205组200接收，与蜂窝电话网140的通信被保持。
通过合并图2的收发机发射路径和图3的收发机接收路径，完整的全双工蜂窝电话业务提供给宏服务小区业务区110和微微服务小区业务区150。微微服务小区覆盖只提供给处于建筑物100内的微微服务小区业务区150，而宏服务小区覆盖既提供给处于建筑物100内的微微服务小区业务区150，也提供给处于建筑物100外的宏服务小区业务区110。在本发明的这个第一实施例中，宏服务小区覆盖和微微服务小区覆盖通过共享多个天线160、基站120和到蜂窝电话网140的通信链路145而提供。
现在再参考图4，其中结合蜂窝系统框图，说明了本发明第二实施例的发射路径。正如本发明的第一实施例，本发明的第二实施例包括由一个或多个收发机205组成的收发机组210，向微微服务小区业务区150提供蜂窝电话业务。收发机205组210通过发送复接器170和通信链路145与蜂窝电话网140通信。本发明的第二实施例也包括连接到天线450的中继器440，在与宏服务小区110关联的无线频率上提供蜂窝电话业务。但是，不象第一实施例，中继器440不在处于建筑物100外的宏服务小区业务区110中提供蜂窝电话业务。但是，中继器440确实在处于建筑物100内的微微服务小区业务区150内提供宏服务小区覆盖。处于远端的基站410通过通信链路420与蜂窝电话网140通信。基站410连接到天线430，向建筑物100外的宏服务小区业务区110提供蜂窝电话业务。中继器440从处于远端的基站410接收宽带信号传输，并产生输出信号461，作为输入提供给合并器470。合并器470将所有的发射机输出信号460与中继器输出信号461合并成单个合并输出信号480，传递到处于建筑物100内的多个天线160。当蜂窝电话在建筑物100外、宏服务小区业务区110内操作时，它通过天线430从基站410接收蜂窝电话业务。同时，中继器440通过天线450拾取来自基站410的传输，并通过多个天线160在建筑物100内重发这些信号。当蜂窝电话在建筑物100内移动、而且从天线430发射的信号开始衰落时，蜂窝电话继续通过中继器440和多个天线160从基站410接收传输。
现在再参考图5，其中结合蜂窝系统框图，说明了本发明第二实施例的接收路径。正如本发明的第一实施例，本发明的第二实施例包括由一个或多个收发机205组成的收发机组210。收发机205组210通过发送复接器170和通信链路145与蜂窝电话网140通信。收发机205组210通过多个天线160向处于建筑物100内的微微服务小区业务区150提供蜂窝电话覆盖。本发明的第二实施例也包括连接到天线450的中继器440，在与宏服务小区110关联的无线频率上提供蜂窝电话业务。
但是，不象第一实施例，中继器440不在处于建筑物100外的宏服务小区业务区110中提供蜂窝电话业务。但是，中继器440确实在处于建筑物100内的微微服务小区业务区150内提供宏服务小区覆盖。处于远端的基站410通过通信链路420与蜂窝电话网140通信。基站410连接到天线430，向宏服务小区业务区110提供蜂窝电话业务。中继器440从分解器500接收信号510并将其通过天线450向处于远端的基站410发射。
来自处于基站物100内的蜂窝电话的传输由多个天线160拾取并输入到分解器500。分解器500复制该信号并向每个收发机205和中继器440提供多份拷贝510。
当蜂窝电话在建筑物100外、宏服务小区业务区110内操作时，它通过天线430从基站410接收蜂窝电话业务。当蜂窝电话在建筑物100内移动时，来自蜂窝电话的传输由多个天线160拾取，而且该信号通过分解器500被中继器440接收。中继器440在建筑物100外通过天线450重发该信号。重发的信号通过天线430被基站410接收，而且与蜂窝电话网140的通信通过中继器440并通过通信链路420建立。
尽管本发明方法和设备的优选实施例已经在附图中说明并在前面的详细描述中描述，但是应该理解发明不仅限于所揭示的实施例，而是能够在不背离如下权利要求所提出并定义的发明精神前提下进行很多重组、修改和替换。
