具体实施方式
现在参考附图描述一个或多个实施例,其中相同的标号贯穿全文被用来指相同的元件。在以下描述中,为了解释,阐述各种细节,以便提供对各种实施例的透彻理解。但是,很显然,各种实施例没有这些具体细节也可以实践(并且无需应用于任何特定的联网环境或标准)。
为了提供到附加基站的网络连通性,将微小区和宏小区连接到核心网络的回程网络对应地扩展。类似地,为了提供到分布式天线系统的网络连通性,连接基站和它们的分布式天线的通信系统对应地扩展。由于在共同使用的频率中可用的带宽有限,所以提供无线回程和联网连接是困难的。光纤和缆线具有带宽,但是,由于小小区部署的分布性质,安装连接会是成本高昂的。
出于这些考虑以及其它考虑,在一个或多个实施例中,系统包括存储可执行指令的存储器以及耦合到存储器的处理器,以促进可执行指令的执行,以执行包括促进信号的接收和利用该信号调制载波信号的操作,其中载波信号是毫米波信号。操作还包括基于载波信号和该信号生成传输。操作还包括经由耦合设备将该传输作为导线的表面上的导波来发射。
在另一个实施例中,方法包括由包括处理器的设备接收信号和利用该信号调制载波。该方法还可以包括基于载波信号和所述信号生成传输,其中该传输是毫米波传输。该方法还可以包括将该传输作为导线上被引导的表面波来发射。
在另一个实施例中,装置可以包括被配置为组合信号和载波的混频器。该装置还可以包括被配置为基于所述信号和载波生成传输的发送器,其中该传输具有对应于毫米波段的波长。该装置还可以包括被配置为将该传输作为导线表面上的导波来发射的耦合设备。
本文所述的各种实施例涉及提供用于小小区部署的表面波通信系统和/或用于小小区部署的回程连接的系统。不是建立新的结构和安装附加的光纤和缆线,本文所述的实施例公开了使用高带宽、毫米波(30GHz-300GHz)通信和现有的电力线基础设施。以上经由电力线的地面网络连接可以提供到分布式基站的连通性。
在另一个实施例中,基站节点和/或天线可以安装在电线杆上,并且网络连接可以由经由节点之间的电力线发送毫米波表面波传输的发送器提供。具有一个或多个基站的单个站点还可以经电力线经由表面波传输连接到分布式天线系统,其中蜂窝天线位于节点处。
现在转向图1,示出了根据本文描述的各方面的表面波通信系统100的示例非限制性实施例。表面波通信系统100包括无线电设备102,无线电设备102可通信耦合到发射沿导线106行进的导波110的耦合设备104。
无线电设备102可以接收信号并基于该信号和载波生成传输。载波信号由该信号调制,并且结果得到的传输可以被波导108带到耦合设备104。在实施例中,无线电设备102接收来自基站设备的信号,该信号被定向到分布式天线。在另一实施例中,无线电设备102可以经由到现有网络基础设施的网络连接接收信号,其中所述网络连接是经由物理或无线连接的网络连接。网络连接可以经由光纤和/或缆线,或者通过高带宽微波连接。然后,由无线电设备102生成的传输可以被朝通信耦合到导线106的基站设备定向。
波导108可以促进从无线电设备102到耦合设备104的传输的运输。在实施例中,波导108可以是中空的导电金属管,它可以将毫米波段传输从无线电设备102运输到耦合设备104。在其它实施例中,当耦合设备104包括用于组合信号和载波信号的混频器时,波导108可以是诸如缆线的传输线,并可以将信号从接收网络连接的调制解调器或其它设备运输到耦合设备104。
在实施例中,耦合设备104是附连到导线106的平面天线并且被配置为沿导线106的表面发射导波110。在实施例中,耦合设备104可以通过感应式地耦合在导线106中流动的电力来被供电。电力也可以被传递到无线电设备102上。在其它实施例中,耦合设备104和无线电设备102可以通过电池或通过太阳能或其它电源供电。
导波110可以是沿导线106传播的毫米波段的波。导线106充当这样一种类型的波导,它通过将电磁波的传播速度减缓至低于自由空间速度来起作用,从而使波前朝导线106稍微向内弯曲,这使波被拖拽(entrain)。大半径的弯曲被容忍,但导线106中太尖锐的弯曲将使线路把能量辐射到空间并损失掉。被引导的表面波能够沿绝缘和裸金属缆线两者传播。相应地,导线106可以在一些实施例中绝缘,并且在其它实施例中非绝缘。
在实施例中,传输的波长的尺寸与导线106的周长具有可比性,或者比导线106的周长更小。在例子中,如果导线106的直径为0.5cm,并且对应的周长为大约1.5cm,则传输的波长为大约1.5cm或更小,对应于20GHz或更高的频率。在另一实施例中,传输和载波信号的理想频率是大约38GHz。在实验结果中,当导线106的周长的尺寸与传输的波长具有可比性或者比传输的波长更大时,导波110呈现出多个表面波模式。因此,导波110可以包括多于一种类型的电和磁场配置。当导波110沿导线106传播时,这多种电和磁场配置将从导线106的端到端保持不变。
在其中既没有电场也没有磁场在传播的方向延伸并且所述场径向向外延伸的基本横电磁模式(TEM00)中,模式图案关于导线106的纵轴是对称的。如果模式图案是对称的,则耦合设备104和接收器(未示出)相对于彼此在导线106周围以什么朝向放置都没有关系。但是,根据实验结果,当导线106的周长的尺寸与传输的波长具有可比性或者比传输的波长更大时,呈现出多模行为并且至少一种存在的模式是非对称的,因为当相对于耦合设备104绕导线106旋转接收器时,经历周期性的零。
在实施例中,多种非对称模式存在,并且因此,与被配置为接收第二模式的传输的接收器相比,被配置为接收第一模式的传输的接收器可以相对于耦合设备104具有不同的朝向。在另一实施例中,多个信号可以被多路复用和/或以其它方式组合到传输中,其中每个信号对应于传输的不同模式。因此,接收器可以基于接收器被配置为接收的模式从相同的传输接收不同的信号。
在实施例中,耦合设备104和/或无线电设备102可以确定导线106的直径和/或周长是多少。所述确定可以基于以光学方式或机械方式取得的测量,或者基于在安装过程中输入的数据。基于导线106的直径和/或周长的确定,无线电设备102可以生成具有用于传输的最佳频率的载波信号。
在实施例中,导线分集路径可以被用来基于环境条件提高性能。冗余传输可以经两根不同的导线被发送,一根是绝缘的,一根是非绝缘的。接收传输的导线可以基于环境条件来选择。当导线106绝缘时,在干燥天气下的衰减损耗较低。但是,当下雨或其它不利天气条件存在时,绝缘导线更易于损耗。因此,无线电设备102可以向耦合到绝缘和非绝缘导线的两个或更多个耦合设备(类似于耦合设备104)输出传输。当导线干燥时,接收器(未示出)可以从绝缘导线接收信号。但是,当导线不干燥时,可以从非绝缘导线接收传输。
现在转向图2,示出了表面波通信系统200的示例非限制性实施例的框图。表面波通信系统200包括可通信耦合到发射沿导线206行进的导波210的耦合设备204。波导208可以促进从无线电设备202到耦合设备204的传输的运输。
在实施例中,耦合设备204可以是使耦合设备同轴的波导。波导端口212可被配置为绕导线206的四分之一缠绕。可以包括总共四个波导端口并且电力可以供给每个波导端口。空气缓冲器或介电隔离物可被用来使金属外屏蔽214与导线206绝缘。导波210中模式的结构可以通过调整注入波导端口的电力的相对振幅和相位来控制。
图3示出了根据本文所述各方面的表面波通信系统300的示例非限制性实施例的框图。需要经过专门培训和认证的技术人员对高压和中压电力线进行工作。使电路远离高压和中压电力线允许普通技术人员安装和维护该电路。相应地,在这种实施例中,准光学耦合系统允许基站和无线电源(radio source)从电力线分离。
在与设备的宏观尺寸相比波长小的毫米波频率,毫米波传输可以从一个地方被运输到另一个地方并且经由透镜和反射器被转向,很像可见光。相应地,反射器308可被放在导线306上并确定朝向,使得从无线电源和/或发送器302发送并经由介电透镜304聚焦的毫米波传输平行于导线306反射,使得它被电力线作为表面波310引导。由发送器302发送的透镜模式耦合到导线306。
现在转向图4,示出了表面波通信系统400的示例非限制性实施例的框图。耦合设备406包括2个或更多个可在毫米波段频率工作的单片式微波集成电路(MMIC)404。线内(inline)(平行于导线402)设计产生紧凑的结构,并且MMIC 404非常适合毫米波段工作所需的小尺寸。MMIC辐射耦合到导线402并作为导波408沿导线传播的高强度场。
图5示出了分布式天线系统500的示例非限制性实施例的框图。分布式天线系统500包括通信耦合到宏小区站点502或其它网络连接的一个或多个基站(例如,基站设备504)。基站设备504可以通过光纤和/或缆线、或者通过微波无线连接被连接到宏小区站点502。诸如宏小区站点502的宏小区可以具有到移动网络的专用连接,并且基站设备504可以肩负(piggyback)宏小区站点502的连接。基站设备504可以安装在电线杆516上或附连到电线杆516。在其它实施例中,基站设备504可以是附近的变压器和/或位于电力线附近的其它位置。
基站设备504可以为移动设备522和524提供连通性。安装在电线杆518和520上或在其附近的天线512和514可以从基站设备504接收信号,并且将这些信号发送到比如果天线512和514位于基站设备504处或其附近时宽得多的区域上的移动设备522和524。
应当认识到,为了简化,图5示出具有一个基站设备的三个电线杆。在其它实施例中,电线杆516可以具有更多的基站设备,并且具有分布式天线的一个或多个电线杆是可能的。
耦合设备506可以经连接电线杆516、518和520的(一根或多根)电力线从基站设备504向天线512和514发送信号。为了发送信号,无线电源和/或耦合器506将来自基站设备504的信号上变频(经由频率混合)为毫米波段信号,并且耦合设备506可以发起作为沿导线行进的导波传播的毫米波段表面波(经由图1-4中所示的实施例)。在电线杆518,耦合设备508接收表面波并且可以放大它并在电力线上将其向前发送。耦合设备508还可以从毫米波段表面波提取信号,并且将其向下频移到其原来的蜂窝频带频率(例如,1.9GHz或其它蜂窝频率)。天线512可以将向下频移的信号发送到移动设备522。该过程可以由耦合设备510、天线514和移动设备524重复。
来自移动设备522和524的传输也可以分别由天线512和514接收。直放站508和510可以将蜂窝频带信号调高到毫米波段,并经(一根或多根)电力线将信号作为表面波传输发送到基站设备504。
在实施例中,系统500可以采用分集路径,其中两根或更多根导线在电线杆516、518和520之间捆扎,并且来自基站504的冗余传输作为导波沿着导线的表面被发送。导线可以既绝缘又非绝缘,并且取决于引起传输损耗的环境条件,耦合设备可以有选择地从绝缘或非绝缘的导线接收信号。所述选择可以基于对导线的信噪比的测量,或者基于确定的天气/环境条件(例如,湿度检测器、天气预报,等等)。
现在转向图6,示出了回程系统600的示例非限制性实施例的框图。回程系统600可以提供到宏小区(例如,宏小区618)的网络连接,以代替物理缆线/光纤等。在其它实施例中,回程系统600还可以向住宅或商业位置和其他最终用户提供网络连接。
网络连接602可以由附连到电线杆604的无线电设备606接收,其中无线电设备606组合网络信号与载波信号并且生成被发送到耦合设备608的传输。耦合设备608可以发起或以其它方式发射传输,作为导线610的表面上的导波。在电线杆614上或附近的耦合设备616可以接收传输并将其转发到无线电设备612,无线电设备612将传输下变频并将其转发到宏小区618。应当认识到,虽然图6仅示出了两个电线杆之间的表面波传输的一段路程(leg),但是在其它实施例中,利用耦合设备在一个或多个电线杆处充当直放站的多段路程是可能的。
耦合设备616可以绕导线610相对于耦合设备608确定朝向,以便接收特定模式的传输。所选模式可以是呈现最佳传输特性或最少衰减的模式。回程系统600还可以得利于利用两根或更多根导线的分集路径,一根绝缘并且一根非绝缘。
现在转向图7,示出了用于分布式天线系统的表面波无线电和天线装置700的示例非限制性实施例的框图。系统700包括基站设备704、706和708,基站设备704、706和708向各自小区中的移动设备发送信号并从各自小区中的移动设备接收信号。应当认识到,单纯为了示例的原因,系统700被示为具有3个微小区基站设备。在其它实施例中,基站站点或集群可以包含一个或多个基站设备。还应当认识到,虽然图7对应于用于分布式天线系统的装置,但是类似的装置可以在回程系统中被用来提供到其它基站设备的网络连通性。
基站设备704、706和708的输出可以分别与由本地振荡器714在混频器722、720和718处生成的毫米波载波组合。混频器722、720和718可以使用外差(heterodyning)技术频移来自基站设备704、706和708的信号。这可以在模拟域中进行,并且因此,频移可以不考虑基站设备704、706和708使用的通信协议的类型而进行。随着时间的推移,当新的通信技术被开发出来时,基站设备704、706和708可以被升级或替换并且频移和发送装置可以保留,从而简化了升级。
控制器710可以生成伴随载波的控制信号,并且GPS模块712可以同步用于控制信号的频率,使得可以确定确切的频率。GPS模块712还可以提供用于分布式天线系统的时间参考。
多路复用器/解复用器724可以根据来自控制器510的控制信号频分多路复用来自混频器718、720和722的信号。每个信号可以在微小区704、706和708处被分配信道,并且控制信号可以提供指示与每个信道对应的微小区信号的信息。然后,耦合设备702可以发起沿导线726生成的传输,作为被引导的表面波。
耦合设备702还可以接收由其它耦合设备发送的传输,其中传输的载波携带来自移动设备的定向到基站设备704、706和708的信号。多路复用器/解复用器724可以将子载波信号彼此分离,并且基于信号的信道或者基于控制信号中的元数据将子载波信号定向到正确的基站设备。然后,混频器718、720和722可以从载波提取信号并且将信号定向到对应的微小区。
现在转向图8,示出了示出表面波直放站系统800的示例非限制实施例的框图。表面波直放站系统800包括接收和发送来自位于分布式天线系统或回程系统中的其它耦合设备的传输的耦合设备802和804。
在各种实施例中,耦合设备802可以从另一耦合设备接收传输,其中所述传输具有多个子载波。双工器806可以将该传输与其它传输分离,并且将该传输定向到低噪声放大器(“LNA”)808。在来自本地振荡器812的帮助下,混频器828可将(在毫米波段中的)传输向下频移至固有频率,用于分布式天线系统的蜂窝频带(~1.9GHz)或者用于回程系统的其它频率。提取器832可以在与天线或其它输出部件822对应的子载波上提取信号,并且将该信号定向到输出部件822。对于没有在该天线位置被提取的信号,提取器832可以将它们重定向到另一个混频器836,在那里信号被用来调制由本地振荡器814生成的载波。具有其子载波的载波被指向功率放大器(“PA”)816并且经由双工器820被耦合设备804重新发送到另一个直放站系统。
在输出设备822(在分布式系统中的天线)处,PA 824可以增大(boost)用于传输到移动设备的信号。LNA 826可以被用来放大从移动设备接收到的微弱信号,然后将该信号发送到多路复用器834,多路复用器834将该信号与已经从耦合设备804接收到的信号合并。从耦合设备804接收到的信号已经被双工器820分割,然后传递通过LNA 818,并且被混频器838向下频移。当信号被多路复用器834组合时,它们被混频器830向上频移,然后被PA 810增大,并且分别被耦合设备802和804发送回发射器或发送到另一直放站。
图9示出了与上述系统有关的过程。图9中的过程可以例如分别由图1-8中所示的系统100、200、300、400、500、600、700和800实现。虽然为了解释的简化,方法被示为和描述为一系列方框,但是应当理解和认识到,要求保护的主题不受方框次序的限制,因为一些方框可以按与本文绘出和描述的次序不同的次序发生和/或与其它方框同时发生。而且,不是所示出的所有方框都是实现下文所述的方法所必需的。
图9示出了用于提供如本文所述的表面波通信的方法的示例非限制性实施例的流程图。在步骤902,信号被接收。该信号可以来自基站设备并朝分布式天线定向。在其它实施例中,信号可以来自网络连接并朝基站设备定向。
在步骤904,载波信号利用所述信号被调制。载波信号可以由本地振荡器生成并利用混频器被调制。混频器可以使用外差技术在模拟域中频移信号。相应地,频移可以在不考虑信号对应的通信协议的类型的情况下完成。
在906,生成基于所述载波信号和信号的传输,其中所述传输是毫米波传输。在908,传输可以作为导线上被引导的表面波被发射。导线充当这样一种类型的波导,它通过将EM波的传播速度减缓至低于自由空间速度来起作用,从而使波前朝导线稍微向内弯曲,这使波被拖拽。大半径的弯曲被容忍,但导线中太尖锐的弯曲将使线路把能量辐射到空间并损失掉。被引导的表面波能够沿绝缘和裸金属缆线两者传播。相应地,导线可以在一些实施例中绝缘,并且在其它实施例中非绝缘。
现在参考图10,示出了根据本文所述各方面的计算环境的框图。为了对本文所述实施例的各种实施例提供附加的上下文,图10和以下讨论旨在提供对本文所述实施例的各种实施例可以在其中实现的合适计算环境1000的简要的一般描述。虽然以上已经在可以在一个或多个计算机上运行的计算机可执行指令的一般上下文中描述了实施例,但是本领域技术人员将认识到,所述实施例也可以结合其它程序模块和/或作为硬件和软件的组合来实现。

监视器1044或其它类型的显示设备也可以经由诸如视频适配器1046的接口连接到系统总线1008。除监视器1044之外,计算机通常还包括其它外围输出设备(未示出),诸如扬声器、打印机等。
计算机1002可以利用经由到一个或多个远程计算机(诸如远程计算机1048)的有线和/或无线通信的逻辑连接在联网环境中操作。远程计算机1048可以是工作站、服务器计算机、路由器、个人计算机、便携式计算机,基于微处理器的娱乐设备、对等设备或其它常见的网络节点,并且通常包括以上关于计算机1002所述的元件当中的许多或全部,但是,为了简洁,仅示出存储器/存储设备1050。所绘出的逻辑连接包括到局域网(LAN)1052和/或更大网络(例如广域网(WAN)1054)的有线/无线连通性。这种LAN和WAN联网环境常见于办公室和公司,并且方便企业范围的计算机网络,诸如内联网,所有这些都可以连接到全球通信网络,例如互联网。

Wi-Fi可以允许从家里的沙发、酒店房间的床上或者工作会议室连接到互联网,而无需导线。Wi-Fi是类似于在手机中使用的无线技术的无线技术,所述在手机中使用的无线技术使这种设备(例如计算机)在基站范围内的任何地方在室内和室外发送和接收数据。Wi-Fi网络使用被称为IEEE 802.11(a、b、g、n、ac等)的无线电技术来提供安全、可靠、快速的无线连通性。Wi-Fi网络可以被用来将计算机连接到彼此、连接到互联网并且连接到(可以使用IEEE 802.3或以太网的)有线网络。Wi-Fi网络在无许可的2.4和5GHz无线电频带内以11Mbps(802.11a)或54Mbps(802.11b)的数据速率工作,例如或具有包含这两个频带(双频带)的产品,所以所述网络可以提供类似于在许多办公室使用的基本10BaseT有线以太网网络的真实世界性能。
图11给出了可以实现和采用本文所述的公开主题的一个或多个方面的移动网络平台1110的示例实施例1100。一般而言,无线网络平台1110可以包括便于分组交换(PS)(例如,互联网协议(IP)、帧中继、异步传送模式(ATM))和电路交换(CS)业务量(例如,语音和数据)两者以及控制联网无线电信的产生的部件,例如节点、网关、接口、服务器或完全不同的平台。作为非限制性例子,无线网络平台1110可以包括在电信运营商网络中,并且如本文其它地方所讨论的那样可以被认为是运营商侧的部件。移动网络平台1110包括CS网关节点1112,其中CS网关节点1112可以接口(interface)从像电话网络1140(例如,公共交换电话网(PSTN)或公共陆地移动网(PLMN))的传统网络或信令系统#7(SS7)网络1170接收到的CS业务量。电路交换网关节点1112可以授权并认证从这种网络产生的业务量(例如,语音)。此外,CS网关节点1112可以访问通过SS7网络1170生成的移动性或漫游数据;例如,存储在被访问位置寄存器(VLR)中的移动性数据,该数据可以驻留在存储器1130中。而且,CS网关节点1112接口基于CS的业务量和信令和PS网关节点1118。作为例子,在3GPP UMTS网络中,CS网关节点1112可以至少部分地在网关GPRS支持节点(GGSN)中实现。应当认识到,CS网关节点1112、PS网关节点1118和服务节点1116的功能和具体操作由用于电信的移动网络平台1110所使用的无线电技术提供和指定。
除了接收和处理CS交换业务量和信令,PS网关节点1118还可以授权并认证与被服务的移动设备的基于PS的数据会话。数据会话可包括与无线网络平台1110外部的网络交换的业务量或内容,其中所述网络就像广域网(WAN)1150、企业网1170以及服务网络1180,所述网络可以在局域网(LAN)中实现,也可以通过PS网关节点1118与无线网络平台1110接口。应当指出的是,WAN 1150和企业网1160可以至少部分地实现像IP多媒体子系统(IMS)的服务网络。基于在技术资源1117中可用的无线电技术层,分组交换网关节点1118可以在数据会话被建立时生成分组数据协议上下文;促进分组数据的路由的其它数据结构也可以被生成。为此,在一方面,PS网关节点1118可以包括隧道接口(例如,3GPP UMTS网络中的隧道终止网关(TTG)(未示出)),该隧道接口可以促进与完全不同的无线网络(诸如Wi-Fi网络)的分组通信。
在实施例1100中,无线网络平台1110还包括服务节点1116,基于技术资源1117中可用的无线电技术层,所述服务节点1116传送通过PS网关节点1118接收的数据流的各个分组流。应当指出的是,对于主要依赖于CS通信的技术资源1117,服务器节点可以不依赖PS网关节点1118输送业务量;例如,服务器节点可以至少部分地实现移动交换中心。作为例子,在3GPP UMTS网络中,服务节点1116可以在服务GPRS支持节点(SGSN)中实现。
对于采用分组通信的无线电技术,无线网络平台1110中的服务器1114可以执行各种应用,这些应用可以生成多个完全不同的分组数据流,并且管理(例如,调度、排队,格式化...)这种流。这种应用可以包括对由无线网络平台1110提供的标准服务(例如,供应、计费、客户支持...)的附加特征。数据流(例如,作为语音呼叫或数据会话的一部分的内容)可以被传送到PS网关节点1118,用于数据会话的授权/认证和启动,并且被传送到服务节点1116,用于其后的通信。除了应用服务器,服务器1114还可以包括实用服务器,实用服务器可以包括供应服务器、操作和维护服务器、可以至少部分地实现证书机构和防火墙以及其它安全机制的安全服务器,等等。在一方面,安全服务器保护通过无线网络平台1110被服务的通信,以便除了CS网关节点1112和PS网关节点1118可以制定的授权和认证程序之外,还确保网络的操作和数据完整性。而且,供应服务器可以供应来自外部网络(像由完全不同的服务提供商运营的网络)的服务;例如,WAN 1150或全球定位系统(GPS)网络(未示出)。供应服务器还可以通过关联到无线网络平台1110(例如,被相同的服务提供商部署和运营)的网络供应覆盖,诸如增强室内受限空间的无线服务覆盖并且卸载RAN资源的毫微微小区网络(未示出),以便通过UE 1175增强家庭或商业环境内的订户服务体验。
应当指出的是,服务器1114可以包括被配置为至少部分地赋予(confer)宏网络平台1110的功能的一个或多个处理器。为此,例如,一个或多个处理器可以执行存储在存储器1130中的代码指令。应当认识到,服务器1114可以包括内容管理器1115,其中内容管理器1115以基本上与前文所述相同的方式操作。
在示例实施例1100中,存储器1130可以存储关于无线网络平台1110的操作的信息。其它操作信息可以包括通过无线网络平台1110被服务的移动设备的供应信息、订户数据库;应用智能、定价方案,例如促销费率、统一费率方案、优惠券活动;与用于完全不同的无线电或无线技术层的操作的电信协议一致的技术规范;等等。存储器1130还可以存储来自电话网络1140、WAN 1150、企业网1160或者SS7网络1170当中至少一个的信息。在一方面,存储器1130可以例如作为数据存储部件或作为远程连接的存储器存储的一部分被访问。
为了提供用于所公开主题的各方面的上下文,图11和以下讨论旨在提供对可以实现所公开主题的合适环境的简要的一般描述。虽然以上已经在一个和/或多个计算机上运行的计算机程序的计算机可执行指令的一般上下文中描述了主题,但是本领域技术人员将认识到,所公开的主题也可以结合其它程序模块来实现。一般而言,程序模块包括执行特定任务和/或实现特定抽象数据类型的例程、程序、部件、数据结构,等等。

如将容易认识到的,一个或多个实施例可以采用经过显式训练(例如,经由一般训练数据)以及隐式训练(例如,经由观察UE行为、运营商偏好、历史信息、接收固有信息)的分类器。例如,SVM可以经由分类器构造器和特征选择模块中的学习或训练阶段来配置。因此,分类器可以被用来自动学习和执行多个功能,包括但不限于根据预定标准确定所获取的小区站点中哪个将有利于最大数量的订户和/或所获取的小区站点中哪个将向现有的通信网络覆盖添加最小价值,等等。

此外,词语“示例”和“示例性”在本文中被用来指充当实例或说明。本文被描述为“示例”或“示例性”的任何实施例或设计并不一定要被解释为优于或胜过其它实施例或设计。相反,词语示例或示例性的使用旨在以具体的方式呈现概念。如在本申请中所使用的,术语“或”旨在指包含性的“或”而不是排他性的“或”。即,除非另有指定或从上下文可以清楚,否则“X采用A或B”旨在指任何自然的包含性排列。即,如果X采用A;X采用B;或者X采用A和B二者,则“X采用A或B”在任何以上情况下都满足。此外,如在本申请和所附权利要求书中所使用的,除非另有指定或从上下文清楚看出是针对单数形式,否则冠词“a”和“an”应当一般性地被解释为指“一个或多个”。
