Description

本地区域蜂窝基站
技术领域
本发明涉及蜂窝基站，尤其涉及可方便地用于在诸如家庭或办公室内提供蜂窝服务的用于蜂窝通信网络的基站。
背景技术
通常从能够覆盖大型区域(诸多公里的小区半径)的常规基站提供用于诸如GSM和UMTS等标准的广域蜂窝服务。然而，因为建筑物结构的射频衰减和来自周围建筑物的无线电遮蔽效应，在建筑物内的覆盖可能变得更加复杂。因为使用高阶星座或低扩频因子的信号需要更高的信噪图，对于诸如EDGE和UMTS等目标是提供中速至高速数据的标准，此覆盖问题变得更加困难。因为这些信号通过建筑物结构经受更大的衰减，诸如用于UMTS的高频也加重了此问题。
这些问题的常规解决方案将是部署很多基站和射频中继器系统以增加在建筑物和城市区域内的覆盖。这些解决方案变得成本极高，在居民区内很多基站/天线的附加审美影响形成导致居民反对和运营商的附加法律成本。使用诸如WiFi或蓝牙等短距离无线电接口以处理在家庭或办公室内的蜂窝服务是替代方法，但是要求客户或运营商购买新手机。
最新图表表明超过70％的全部蜂窝呼叫在建筑物内进行，所以此问题形成蜂窝产业未来发展的某些主要阻力。
公知提供无线访问点，例如根据IEEE 802.11标准，其允许计算机用户进行到计算机网络的无线连接，例如互联网，从而能够访问数据。
然而，此类型的无线访问点的限制在于它并不允许由大量现有蜂窝移动通信设备中的任一设备访问。

附图说明
图1是根据本发明的包括基站的系统的方框示意图。
图2是图示根据本发明的基站硬件结构的方框示意图。
图3是图示根据本发明的基站软件结构的方框示意图。
图4图示根据本发明的由基站支持的互连。
具体实施方式
图1是图示系统结构的方框示意图。移动网络运营商(MNO)拥有和操作无线通信网络，包括无线电访问网络10，其包括蜂窝基站网络(未图示)，和核心网络20，其具有到固定电话网络的连接。这些是常规的，除了如下面所描述的。
当在由无线通信网络覆盖的地区内漫游时，移动电话30能够建立与蜂窝基站之一的无线连接，从而与固定电话网络内的其它电话通信，或者与已经建立它们自身的与蜂窝基站的无线连接的其它移动电话通信，因此与固定电话网络通信。
根据本发明，例如在家庭或办公室40或者在需要附加无线覆盖的另一位置内，提供其它基站或访问点50。此访问点50提供用于由其所处的居所业主使用，但是集成到无线通信网络内。也就是说，通过固定或临时地向其分配一组信道中的一些信道，该访问点共享分配给该无线通信网络的部分射频频谱。因而，与其它基站共享该组信道，所述基站可以服务于宏小区、微小区、微微小区，甚至在公共广域网内的“毫微微小区”。因此，当离开访问点50的相邻位置时，移动电话30可以从访问点50漫游到另一个基站，或者当返回访问点50的相邻位置时，可以从另一基站漫游进入访问点50。
因此，访问点50用作相关无线通信网络内的基站。例如，它可以允许整个常规和未修改移动电话30或者其它用户设备使用GSM/GPRS和/或空中接口建立用于语音和/或数据服务的连接。当然，可以支持该访问点50使用任意适当蜂窝无线通信系统的标准空中接口建立与移动电话30的连接。
访问点50具有在家庭或办公室40内用于以太网局域网(LAN)42的连接。如图1所示，访问点50可以在以太网LAN 42连接到一个或多个本地PC或服务器44。
访问点50可以在以太网LAN 42上连接到IP网关设备60。通过数字用户线路(DSL)或者通过诸如数字多媒体有线网络等其它IP传输方法，IP网关设备60提供在诸如互联网等IP网络70上到MNO网络的IP连接。因而，可以使用自家庭或办公室的现有IP连接提供自访问点50的回程。使用通过UMA网关22的UMA标准，通过到MNO核心网络或者无线电访问网络的连接可以提供到运营商网络20的灵活接口。此方法支持使用基于网际协议的语音(VoIP)技术的数据和语音的低成本传输。
由UMA未许可网络控制器(UNC)12提供在IP网络70上从IP网关60到MNO无线电访问网络10的连接，所述控制器已经由3GPP标准化为普通访问网络控制器(GANC)。也可以使用到无线电访问网络10的接口的其它非标准化解决方案作为替代方法。通过使用在访问点和诸如SIP网关或IP多媒体子系统等适当网关之间的SIP接口，可以实现到运营商核心网络的直接连接。
在该图示的实施例中，DSL或电缆IP网关设备60包括规定用于POTS电话或传真设备62的连接，和用于提供IPTV服务给TV 64的音频/视频连接。访问点50包括允许将这些设备集成到MNO网络内，支持用户的复杂新服务的服务环境。
在本发明的替代实施方式内，可以将访问点50集成为在IP网关设备60内的组件；随后，内部IP连接将嵌入的访问点组件链接到IP网关设备内的路由器功能。此配置可以潜在地提供较低的整体成本，并便于运营商寻求提供统一数据、固定语音、多媒体和移动服务的网关单元。
因此，当移动电话30处于家庭或办公室40内，或者在访问点50的覆盖区域内时，它可以以与通过蜂窝无线通信网络内的任何其它基站相同的方式连接到MNO网络内。
图1还图示连接到IP网络70的网络服务器72。如将理解的，在IP网络70是互联网的情况下，将大量服务器和其它设备连接到网络。如下文将更详细描述的，移动电话30的用户可以通过访问点50访问这些设备。
图1还图示连接到IP网络70的管理系统74。由移动网络运营商提供管理系统74，用于管理访问点50的操作，包括控制可用服务。
例如，如上所述，和如下文更详细描述的，移动电话30的用户可以在以太网LAN 42上通过访问点50建立到一个或多个本地PC或服务器44的连接，或者通过IP网关设备60到其连接到的另一设备的连接，或者通过IP网关设备60到连接到IP网络70的网络服务器72的连接。可以在此无线通信网络的核心网络20上不传送业务的情况下，建立这些连接。管理系统74能够定义设备或者IP地址，使用其可以建立此类连接。因此，如果移动网络运营商期望，可以仅使用有限数量的设备或IP地址建立这些连接。
而且，管理系统74能够规定分配给访问点50的信道(其可以由频率、时隙和/或扩频码定义，取决于特定蜂窝无线通信系统)。根据整体网络要求，可以半固定地或者可以定期改变这些信道。
图2是图示访问点50的硬件结构的示意方框图。该结构包括通过诸如ARM AMBA总线等处理器总线80互连的多个功能模块。
访问点50包括各种外部有线接口，包括RJ45以太网10/100接口82，其提供到本地LAN的连接，用于连接到IP网关设备60，从而连接到MNO网络和互联网，还提供到连接到以太网网络的其它设备的访问，例如一个或多个PC 44，或者例如用于先进服务规定的IPTV 64。因此，访问点50可以具有通过标准UMA UNC的修改版本到无线电访问网络10或者通过与普通Iub(UMTS)或Abis(GSM)接口相对的SIP到核心网络的基于IP的接口。
访问点50还包括UMTS用户标识模块(USIM)卡接口84以允许使用标准UMTSSIM卡提供用于访问点50的唯一标识符，从而识别到管理系统74和运营商无线电网络10和核心网络20的单元，进而支持将要提供的各种服务。也可以使用GSM SIM或IMSISIM接口作为替代实施方式。
访问点50还包括协议引擎216，将其实施为由用于加密的专用协处理器88和用于分组处理的专用协处理器90支持的诸如ARM926(具有适当的外围设备)的小型内嵌CPU，其将为主CPU分担特定密集任务。例如，由加密加速器88处理IPSec分组负载的加密，其支持AES和3DES加密协议。访问点50至UNC 12和管理系统74的VPN连接将使用内部加密处理；可以在访问点50外部处理用户VPN加密处理。
主CPU还负责通过主CPU总线80配置和控制该系统内的所有功能块，包括基带调制解调器92和以太网端口82。将包括用于所有系统功能块的配置数据的系统软件映象存储在访问点50内的FLASH存储器94内；存储两个完整系统映象，以便可以从管理系统74将更新后的系统映象下载到访问点50，同时将先前映象保存为中断下载情况下的后退选项。
主CPU外围设备包括：用于软件稳健检查的看门狗(Watchdog)定时器，用于系统内调试的JTAG和序列端口；和用于包括LED状态指示的系统控制、系统功率管理和系统告警收集的GPIO。
访问点50包括用于在900MHz或1800MHz上的GSM的第一射频接口94和用于在2100MHz上的UMTS的第二射频接口96。因此，支持GSM和UMTS的同时操作。对于GSM和UMTS接收路径，上行链路(基站接收)和下行链路(终端接收)频率都是可访问的；对于发射路径，仅下行链路(基站发射)频率是可获得的。在安装时，访问点50从由管理系统74提供的GSM和UMTS载波频率的许可列表中选择出对于GSM和UMTS都具有最低噪声/干扰的下行链路射频载波频率；将由将其接收路径配置为UE模式和禁用其发射路径的访问点50扫描许可的下行链路频率。
设计访问点50以在建筑物内在距离固定或步行(例如不超过10km/h)用户不超过50米的距离上提供蜂窝服务，从而与常规宏小区基站相比，动态地降低所需要的发射功率。然而，可以在任一功率电平上操作和处理任意类型的移动用户的任意基站上提供在此描述的功能。
射频接口94，96通过调制解调器模拟接口98连接到基带调制解调器92，其支持用于GSM和UMTS基站调制解调器的抽样速率处理、码片速率处理(仅UMTS)和用于GSM和UMTS的符号速率处理。
访问点50将具有有限的GSM移动站(MS)和UMTS用户装置(UE)调制解调器功能，从而允许访问点50恢复来自本地GSM/UMTS基站和其它相邻访问点的广播信道(BCH)。将在初始安装过程中进入UE调制解调器模式以观察本地射频环境，和在初始安装之后在定期间隔上监视射频环境，如果需要，修改访问点配置。
使用基于软件的结构实施基带调制解调器92以保证在最长5年的现场寿命上的高适应性，例如可升级以允许进一步增强将要在现场内发送的HSDPA或EDGE服务，而不需要替换该单元。
访问点50包括在5年使用寿命上为GSM和UMTS基站操作提供足够精确性的定时和频率基准100。
因此，该访问点50的实施例提供各种操作特征。例如，它是用户可安装、自配置和适应周围射频环境的。可以将访问限制于使用标准GSM/UMTS协议的指定用户。此外，在连接到公共以太网LAN的大型室内区域内安装多个访问点可以管理在它们自身之间的越区切换，而不需要无线电网络10内的其它系统或者运营商蜂窝网络的核心网络20的干预。
图3提供在访问点50的协议引擎86以及加密加速器88和分组处理加速器90上运行的软件的结构概念图，重点是服务环境及其到较低栈层内的控制路径。
访问点50包括服务平台，其可以是四个数据网络的潜在联合，即外部MNO核心网络20、外部互联网70、诸如移动电话30的移动设备(通过GSM/UMTS)和家庭网络(通过以太网)。
访问点堆栈结构包括功能强大的服务环境120。服务环境是基于Java的，并包括Java虚拟机122和形式为API接口的访问点库124，所述接口允许应用126与堆栈低层交互以控制呼叫/数据对话、业务路由选择和诸多其它功能。服务环境120还包括Web服务器128，其提供到用户的便利接口，用于配置和监视，还用于选择和购买期望应用，带有用于通过本地PC的调试和维护的安全保护选项。服务环境120还包括管理系统(MS)客户机130，其配置访问点50和监视其操作的各个方面。MS客户机130控制规定系统，以便可以替换和重新启动在如图3所示的系统内的任意软件组件。
如上所述，服务环境120还包括各种应用126，例如由移动网络运营商或IP网关60供应商建立的，可以将其预先安装在访问点50内，或者可以通过在运营商安装或者在用户请求时从运营商网络下载而发送，例如作为可计费服务的一部分。
软件网络(ZN)层132提供对话控制功能以管理和执行确定如何配置访问点50的服务流和策略，和操作用于任意特定移动网络运营商(MNO)配置和终端用户设置。通过管理系统(MS)客户机130、Java应用或者通过Web服务器128，将配置参数装载到ZN数据库134。这些参数提供在访问点内用于对话控制操作的“规则”。对话控制功能包括：用于在MNO核心网络上的访问点50的登记、呼叫控制和业务流/路由选择的策略的实施；用于登记、呼叫控制和业务流的UMA客户机(下文将进一步描述)的控制；和在发送GSM/UMTS服务和通过IP网关60与其它服务接口的访问点ZAP资源的有效管理。
在软件的网络(ZN)层132之下，存在非访问层(NAS)功能136，需要它以便当MNO GSM/UMTS核心网络20未连接到访问点50时将服务提供给UE。此功能支持访问点50提供普通GSM/UMTS服务，例如移动用户定制的SMS和MMS，同时未以常规方式连接到GSM/UMTS核心网络。为了提供此类服务，访问点50包含通常在移动交换中心(MSC)、服务GPRS服务节点(SGSN)、GSM基站子系统(BSS)和UMTS无线电网络子系统(RNS)内包含的核心网络功能的压缩子集。
因此，如在访问点50内实施的非访问层136提供在常规GSM/UMTS网络内通常包含在MSC和SGSN节点内的各种功能。一种这样的特征是呼叫控制(CC)。这支持在两个对等实体之间的呼叫建立，主要用于电路交换连接。
NAS层136还提供：对话管理(SM)，用于控制分组数据对话；短消息服务(SMS)功能，用于在访问点50和网络SMS服务中心之间的SMS消息传输；辅助服务(SS)，例如呼叫等待、呼叫保持和多方呼叫；移动性管理/GPRS移动性管理(MM/GMM)，用于管理UE移动性单元，例如位置登记、鉴权和加密；和与可以安装在访问点50内的USIM卡相关的控制功能。访问点50还提供分组路由选择性能，其本质上是在常规网络内的GGSN功能。
在NAS功能之下，存在访问层功能，具体而言UMTS访问层功能138和GERAN访问层功能140。
UMTS访问层功能138包括一些SGSN功能、无线电网络控制器(RNC)功能和在基带调制解调器92上实施的到UMTS物理层的接口。对于支持UMTS的所有访问点服务都需要RNC和物理层接口功能，而与所使用的核心网络接口无关。

GSM/GPRS层1
到在基带调制解调器内实施的GSM/GPRS/EDGE调制解调器功能的接口。
因而，如上所述，访问点50包括通常位于用于UMTS和GSM标准的无线电访问网络的更高层内的一些功能。这是部分因为，为了能够将数据业务路由选择到MNO核心网络，或者到互联网或者到在局域网上的设备，访问点50必需访问流向和流出远程设备的数据分组。然而，非常希望通过与在其余蜂窝网络内使用的相同加密机制确保到蜂窝设备的空中接口。因此，如果希望予以维持，因而，为了支持上面描述的服务和路由选择性能，访问点50应当包含用于空中接口加密的端接功能(即在UMTS内的RLC/MAC层)。
在访问点50内运行的软件还包括UMA客户机142，允许访问点50在非标准配置内使用UMA协议。具体而言，设计标准UMA协议以支持GSM MS或者UMTS UE，其包括UMA客户机和诸如IEEE 802.11b/g或蓝牙等未许可频谱空中接口，以使用未许可频谱与GSM/UMTS核心网络通信。然而，在访问点50内的实施方式使用UMA客户机作为GSM/UMTS基站的网络接口的一部分，以便可以修改开发以通过未许可网络控制器(UNC)与GSM/UMTS核心网络通信的UMA协议以管理由该基站处理的呼叫，包括到/自宏网络的越区切换。如先前指出的，可以使用SIP接口作为替代方法。
访问点50还包括一个或多个IP设备客户机144，以支持在“移动域”(驻留到访问点50上的移动电话和到MNO核心网络20内的业务路径)和其它IP设备之间的呼叫、控制信息或数据的传输，所述其它IP设备例如是用于固定线路电话/传真服务的在IP网关60内的VoIP/POTS端口、在用于IPTV和/或视频服务的IP网关60内的AV端口、在本地以太网LAN上的PC或服务器44或者通过IP网关60在互联网70上可访问的远程网页和/或服务器72。
每个IP设备客户机144访问在访问点50内的业务路径，并可以由在ZN层132内的对话控制器控制，所述控制器可以开始和结束与可访问IP设备的呼叫/数据对话。在访问点50内包括专用于特定设备或服务的IP设备客户机的软件结构支持将在访问点50内路由选择来自该特定设备或服务的业务，以便可以将其连接到通过GSM或UMTS访问层访问的GSM/UMTS移动设备或者通过UMA客户机访问的MNO核心网络。
此外，每个IP设备客户机144访问在LAN上的其它设备，并还访问在互联网70上可访问的其它设备。例如，通过使用适当的IP设备客户机144，可以在互联网70上将连接到访问点50的POTS电话连接到另一个POTS电话，从而进行语音呼叫。
而且，每个IP设备客户机144访问MNO的移动网络。具体而言，连接到LAN 42的任意设备或者连接到IP网关60的任意设备可以具有IP设备客户机144，该客户机可以关联自身与连接到USIM接口84的USIM卡。从MNO网络的观点来看，任一此类设备因此看起来将是移动的，并将允许其访问MNO网络。因此，通过提供具有适当期望功能的设备，随后使用USIM卡以允许在MNO核心网络上将该设备连接到一个或多个其它设备，可以将各种服务提供给用户。
进一步使用连接到USIM接口84的USIM卡以允许驻留到访问点上的移动电话以类似于多扩展无绳电话系统的方式工作。在该特定服务配置内，在访问点50内的USIM卡承载IMSI标识符和MSISDN编号，其实际上定义安装访问点50的家庭或办公室的电话号码，尽管它在移动网络运营商的系统看起来是移动号码。当呼叫在访问点50内USIM卡的MSISDN编号时，振铃驻留到访问点50的全部移动电话，直到它们中的一个应答。以这种方式，将把到个人的来话呼叫引导到该个人的移动电话的MSISDN编号，因此可能不同于通过呼叫MSISDN编号呼叫在家庭或办公室内任一用户的呼叫。当呼叫访问点自身的MSISDN编号时，则改变访问点50的呼叫处理功能。
图4是图示在本发明一种实施例中支持的业务和控制互连的示意图。在图4图示的实施例中，软件包括三个IP设备电话机，即可以通过IP网关60的VoIP端口连接到POTS电话62的第一IP设备客户机146，可以在LAN上连接到本地PC或服务器44的第二IP设备客户机148和可以在IP网络70上连接到互联网设备72上的网站的第三IP设备客户机150。因此，服务环境120包括POTS应用152、PC应用154和与这三个IP设备客户机对应的网站应用156。在这些情况下，在将要连接到诸如IP网关60、本地PC44和/或GSM/UMTS移动设备30的设备内还可能将需要专用于特定服务的应用软件。通过操作访问点50的MNO，可以提供适当的应用软件，从而便于期望的整体服务。
因此，在服务环境120内操作的应用能够开始和结束与驻留到访问点50和MNO核心网络20上的移动站的呼叫或数据对话，和通过IP设备客户机，能够访问和控制在网关、连接到以太网LAN的设备和通过互联网可访问的远程设备内的服务。用户还能够通过MS客户机130与管理系统74交互。
由专用于在访问点50服务环境内执行的服务的Java应用处理“呼叫”或连接的开始和结束的控制。在访问点50的API库(如图3所示)内提供的功能允许通过在访问点50的网络层132内实施的对话控制的呼叫控制和路由选择。
如上所述，访问点50执行空中接口加密，其常规上不在蜂窝网络的基站内，而是在核心网络内执行。这意味着访问点50能够确定正在进行的呼叫类型。这又允许访问点50将附加服务提供给驻留移动设备。
例如，可以使用在服务环境内运行的应用补充驻留到访问点50的移动电话的性能。例如，遗留下的GSM和UMTS移动站在驻留到访问点50上时可以利用通过系统可用的新服务性能，例如IMS。访问点50可以用作在新核心网络服务平台和遗留移动电话之间的互通功能或“代理”。例如，当在网络内部署IMS时，规划提供即时消息器(IM)功能的所谓基于存在的服务将在未来手机内可用。然而，将要求用户使用兼容设备替换他们的手机以使用这些服务。相反地，访问点应用可以提供在遗留移动设备和新核心网络存在服务平台之间的互通；当用户的移动设备漫游到访问点50上时，指示用户在网络上“出现”。发送到驻留到访问点50上的用户的即时消息可以由访问点转换成常规SMS消息，随后将其发送给用户。类似地，可以将从驻留到ZAP上的用户返回的SMS消息转换成用于发送回核心网络的其它消息格式。
相同原理的另一应用可以是“按键通话”性能，其中访问点50提供在遗留移动设备和在MNO核心网络内的中央呼叫服务器之间的互通功能。
因此，位于基于家庭或办公室的访问点50内的服务环境120有效地联合四个不同网络，即MNO核心网络20(通过IP网关60)、互联网(也通过IP网关60)、本地LAN(通过以太网端口)和驻留到访问点50上的本地移动设备(通过GSM或UMTS空中接口)。
例如，这允许各种服务选项。
可以在驻留到访问点50上的GSM/UMTS移动设备和连接到本地以太网LAN网络的设备，例如PC/服务器、网络摄影和其它家庭安全和/或家庭自动化传感器和传动器，之间建立直接连接。此连接位于访问点50本地，并不需要涉及MNO核心网络以承载业务。
可以在驻留到访问点50的GSM/UMTS移动设备和互联网之间建立直接连接，而不需要涉及MNO核心网络。这允许GSM/UMTS移动设备访问网页和互联网内容，而不因为此业务加重核心网络20的负担，因此，对于MNO来说优点在于其基础设施成本可能较低。
可以在驻留到访问点50上的GSM/UMTS移动设备和驻留到可通过互联网直接访问的其它访问点上的GSM/UMTS设备之间建立直接连接。此性能允许将诸如用户在它们的家庭访问点50或者语音/视频呼叫等信息在互联网上直接从一个访问点传送给另一个访问点，而不需要涉及MNO核心网络20承载该业务。
可以在MNO核心网络20和在IP网关设备60内的设备或应用和连接到本地以太网LAN网络的其它设备或应用之间建立直接连接。此性能例如将允许：
i.使用在IP网关设备60上的VoIP/POTS端口进行在MNO网络内的电话呼叫，使用访问点50内的USIM卡以定义POTS电话的“移动号码”和其它必需细节；
ii.使用在IP网关设备60上的IPTV以在所连接的TV屏幕上显示输入视频呼叫、移动电视流或MMS消息；
iii.在MNO广域网内漫游的用户通过它的GSM/UMTS移动设备和MNO核心网络20和MNO无线电网络10访问它的家庭PC或服务器，或者连接到本地以太网LAN的家庭安全和/或自动化设备。
因此，访问点50向用户提供改进的服务，同时降低移动网络运营商的成本。
