Description

IP连接的无线电基站的无线电网络控制器选择
技术领域
本发明涉及无线电信，具体来说，涉及无线电接入网的“毫微微”或“微微”无线电基站的操作。背景技术
在典型的蜂窝式无线电系统中，无线用户设备单元(UE)经无线电接入网(RAN)与一个或多个核心网络进行通信。用户设备单元(UE)可以是移动台，例如移动电话(“蜂窝”电话)和具有移动终端的膝上型计算机，因而可以是例如便携、袖珍、手持、计算机内置或者车载移动装置，它们与无线电接入网进行语音和/或数据通信。或者，无线用户设备单元可以是固定无线装置，例如作为无线本地环路的组成部分的固定蜂窝装置/终端等。
无线电接入网(RAN)覆盖分为几小区的地理区域，其中各小区由基站提供服务。小区是由基站站点处的无线电基站设备提供无线电覆盖的地理区域。各小区通过在小区中广播的唯一识别码来标识。基站通过空中接口与基站范围内的用户设备单元(UE)进行通信。在无线电接入网中，几基站通常(例如通过陆线或微波)连接到无线电网络控制器(RNC)。无线电网络控制器有时也称作基站控制器(BSC)，它监控并协调所连接的多个基站的各种活动。无线电网络控制器通常连接到一个或多个核心网络。核心网络具有两个服务域，其中RNC具有与这两个域的接口。
无线电接入网的一个实例是通用移动电信系统(UMTS)陆地无线电接入网(UTRAN)。UMTS是第三代系统，在某些方面是以欧洲开发的称作全球移动通信系统(GSM)的无线电接入技术为基础的。UTRAN实质上是向用户设备单元(UE)提供宽带码分多址(WCDMA)的无线电接入网。第三代合作伙伴项目(3GPP)已经着手进一步发展UTRAN和基于GSM的无线电接入网技术。
本领域的技术人员理解，在WCDMA技术中，公共频带允许用户设备单元(UE)和多个基站之间同时通信。在接收站通过基于使用高速伪噪声(PN)码的扩频CDMA波形特性来区别占用公共频带的信号。这些高速PN码用来调制从基站和用户设备单元(UE)发射的信号。使用不同PN码(或时间上偏移的PN码)的发射机站产生能够在接收站单独被解调的信号。高速PN调制还允许接收站方便地通过结合发射信号的几不同传播路径从单个发射站产生接收信号。因此，在CDMA中，在从一个小区到另一个小区进行连接切换时，用户设备单元(UE)不需要转换频率。这样，在始发小区继续为连接提供服务的同时，目标小区可支持与用户设备单元(UE)的连接。由于用户设备单元(UE)在切换过程中始终通过至少一个小区进行通信，因此呼叫没有中断。因此称作“软切换”。与硬切换相比，软切换是“中断前进行的”转换操作。
包含无线电接入网的其它类型的电信系统包括：全球移动通信系统(GSM)；高级移动电话服务(AMPS)系统；窄带AMPS系统(NAMPS)；全接入通信系统(TACS)；个人数字蜂窝(PDC)系统；美国数字蜂窝(USDC)系统；以及EIA/TIA IS-95中描述的码分多址(CDMA)系统。
在UTRAN中存在几种受关注的接口。无线电网络控制器(RNC)和核心网络之间的接口称作“Iu”接口。无线电网络控制器(RNC)与其基站(BS)之间的接口称作“Iub”接口。用户设备单元(UE)和基站之间的接口称作“空中接口”或“无线电接口”或者“Uu接口”。在某些情况下，连接涉及源和服务RNC(SRNC)以及目标或漂移RNC(DRNC)，其中SRNC控制连接，但连接的一个或多个多样分支由DRNC处理。RNC间传输链路可用于源RNC和漂移或目标RNC之间的控制和数据信号的传输，并且可以是直接链路或者逻辑链路。无线电网络控制器之间(例如服务RNC(SRNC)与漂移RNC(DRNC)之间)的接口称作“Iur”接口。
无线电网络控制器(RNC)控制UTRAN。在实现其控制作用中，RNC管理UTRAN的资源。由RNC管理的这类资源其中包括基站发射的下行链路(DL)功率、基站感觉到的上行链路(UL)干扰以及位于基站的硬件。
本领域的技术人员理解，对于某个RAN-UE连接，RNC能够具有服务RNC(SRNC)的作用或者具有漂移RNC(DRNC)的作用。如果RNC是服务RNC(SRNC)，则该RNC负责与用户设备单元(UE)的连接，例如，它完全控制无线电接入网(RAN)中的连接。服务RNC(SRNC)连接到核心网络。另一方面，如果RNC是漂移RNC(DRNC)，则它通过提供与用户设备单元(UE)的连接所需的无线电资源(在漂移RNC(DRNC)控制的小区中)来支持服务RNC(SRNC)。包含漂移无线电网络控制器(DRNC)以及由漂移无线电网络控制器(DRNC)通过Iub接口控制的基站的系统在本文中称作DRNC子系统或DRNS。RNC被说成是通过Iub接口与其连接的基站的控制RNC(CRNC)。这个CRNC作用不是UE特定的。CRNC其中还负责处理通过Iub接口与其连接的基站中的小区的无线电资源管理。
一些运营商正在调查使用小无线电基站(“RBS”)来为有限数量的用户提供家庭或小区域WCDMA覆盖的可能性，其中小无线电基站(“RBS”)在一些上下文中又称作“毫微微RBS”和/或“家庭RBS”和/或“微微RBS”和/或“微RBS”。按照这种调查，小RBS将为终端用户(例如为用户设备单元(UE))提供常规WCDMA覆盖，并且将使用某种基于IP的传输连接到RNC。这样提供的覆盖区域称作“毫微微小区”(以指示覆盖区域比较小)。毫微微小区的其它术语包括“微微小区”或“微小区”，它与宏或标准无线电基站(RBS)覆盖的宏小区形成对比。
基于IP的传输的一个备选方案是使用固定宽带接入(例如xDSL、Cable等)将家庭RBS连接到RNC。另一个备选方案是使用无线宽带接入(例如HSDPA和增强上行链路、或WiMAX)。图5更详细地示出两种不同的回程备选方案。第一个备选方案标记为“xDSL回程”，而第二个备选方案标记为“WiMAX回程”。
一般来说，普通的WCDMA基站(宏RBS)能够使用基于IP的传输连接到RNC。运营商的工作人员、如拥有或维护无线电接入网(RAN)的宏RBS节点和RNC节点的运营商公司的职员通常安装宏RBS节点。作为安装的一部分，用宏RNC所连接到的RNC的IP寻址信息(DNS名称、完全合格域名FQDN或IP地址)人工配置宏RBS。
相反，毫微微RBS通常由终端用户而不是由网络运营商来安装。终端用户还能够将毫微微RBS在地理上从一个地方移动到另一个地方，而无需运营商能够或愿意控制毫微微RBS的重新定位。这种用户指导的重新定位要求：毫微微RBS无论安装或设置在什么位置，它都应当连接到正确的RNC。“正确的RNC”或“优选的RNC”或者“适当的RNC”在这个方面是控制无线电接入网(RAN)的重叠宏小区的相同RNC。
到正确的RNC的连接是重要的，因为例如它还改进毫微微RBS与宏RBS小区之间的漫游和切换所需的相邻小区列表的构成。另外，它还使控制节点之间的网络信令最小化。
因此，用RNC IP寻址信息人工配置RBS的当前技术不适用于毫微微RBS的情况，因为例如毫微微RBS将由终端用户进行安装。
因此，所需的以及本文所提供的目标是用于连接到正确的RNC以便为毫微微RBS、如IP连接的毫微微RBS提供服务的方法、技术、装置和系统。发明内容
方法和装置使毫微微无线电基站能够连接到无线电接入网中用作毫微微无线电基站的活动无线电网络控制器节点的适当无线电网络控制器节点。毫微微无线电基站准备节点地址查询，它用来获得适当无线电网络控制器节点的因特网协议(IP)地址。在接收到对节点地址查询的响应时，毫微微无线电基站还使用适当无线电网络控制器节点的因特网协议(IP)地址连接到作为其活动无线电网络控制器节点的适当无线电网络控制器节点。
在一些示例实施例和模式中，通过使用从毫微微无线电基站的常驻接收器得到的无线电接入网的系统信息(例如位置指示信息)来实现连接。毫微微无线电基站使用系统信息的至少一部分来准备节点地址查询，并使用节点地址查询来获得适当无线电网络控制器节点的因特网协议(IP)地址。在接收到对节点地址查询的响应时，毫微微无线电基站还使用适当无线电网络控制器节点的因特网协议(IP)地址连接到作为其活动无线电网络控制器节点的适当无线电网络控制器节点。
在该技术的一个方面涉及一种操作无线电接入网的方法。该方法包括以下基本示例步骤：准备并发送节点地址查询；使用节点地址查询来获得适当无线电网络控制器节点的因特网协议(IP)地址；以及使用因特网协议(IP)地址将毫微微无线电基站连接到作为毫微微无线电基站的活动无线电网络控制器节点的适当无线电网络控制器节点。在一些示例实施例和模式中，该方法还包括：在毫微微无线电基站并通过无线电接口获得在无线电接入网中广播的系统信息，以及使用系统信息的至少一部分来准备并发送节点地址查询。
该技术的另一个方面涉及包括常驻无线电接收器的毫微微无线电基站的一个示例实施例，常驻无线电接收器用于通过空中接口接收在无线电接入网中广播的系统信息。毫微微无线电基站还包括用于使用系统信息的至少一部分来准备节点地址查询的部件，以及因特网协议(IP)接口。IP接口用于向数据库发送包含系统信息的至少一部分的节点地址请求查询，用于接收作为对查询的响应的适当无线电网络控制器节点的因特网协议(IP)地址，以及用于使用适当无线电网络控制器节点的地址将毫微微无线电基站连接到作为至少一个毫微微无线电基站的活动无线电网络控制节点的适当无线电网络控制器节点。
该技术的又一个方面涉及无线电接入网，它包括数据库、多个无线电网络控制器节点以及如上所述的至少一个毫微微无线电基站。
在不同的实现中，由覆盖毫微微小区的宏小区中的宏无线电基站广播的并由毫微微无线电基站接收的系统信息包括下列至少一个：(1)PLMN-ID；(2)位置区域代码(LAC)；以及(3)小区识别码(CI)。
在一些实施例和模式中，毫微微无线电基站使用系统信息的至少一部分来构造或准备以完全合格域名(FQDN)形式的节点地址查询。完全合格域名(FQDN)然后用来询问域名系统(DNS)数据库，以便获得用于连接到毫微微无线电基站的适当无线电网络控制器节点的因特网协议(IP)地址。完全合格域名(FQDN)至少部分地使用广播系统信息的至少一部分来形成，它可包括下列中两个或更多个的几部分的组合：(1)PLMN-ID；(2)位置区域代码(LAC)；以及(3)小区识别码(CI)，这种组合有可能是下列中两个或更多个的几部分的并置：(1)PLMN-ID；(2)位置区域代码(LAC)；以及(3)小区识别码(CI)。
在一些示例实施例和模式中，毫微微无线电基站直接向域名系统(DNS)数据库发送包含完全合格域名(FQDN)的询问，以便获得适当无线电网络控制器节点的因特网协议(IP)地址。在其它示例实施例和模式中，毫微微无线电基站向无线电网络控制器节点发送包含完全合格域名(FQDN)的询问。无线电网络控制器节点将完全合格域名(FQDN)转发到域名系统(DNS)数据库，以便获得适当无线电网络控制器节点的因特网协议(IP)地址。在接收到适当无线电网络控制器节点的因特网协议(IP)地址时，无线电网络控制器节点将其转发到毫微微无线电基站。在又一些示例实施例和模式中，毫微微无线电基站向通用重定向器节点发送包含完全合格域名(FQDN)的询问，并且通用重定向器节点将完全合格域名(FQDN)转发到域名系统(DNS)数据库，以便获得适当无线电网络控制器节点的因特网协议(IP)地址。在接收到适当无线电网络控制器节点的因特网协议(IP)地址时，通用重定向器节点将其转发到毫微微无线电基站。
在一些实施例和模式中，毫微微无线电基站使用系统信息的至少一部分和毫微微无线电基站的标识符中的之一或二者，来构造或准备以节点地址请求消息形式的节点地址查询。毫微微无线电基站将节点地址请求消息发送到无线电网络控制器节点或通用重定向器节点。无线电网络控制器节点或通用重定向器节点根据具体情况将节点地址消息中包含的系统信息的至少一部分和毫微微无线电基站的标识符中的之一或二者转发到数据库，以便获得适当无线电网络控制器节点的因特网协议(IP)地址。数据库可协同定位在无线电网络控制器节点和通用重定向器节点，或者与它们不同。在接收到适当无线电网络控制器节点的因特网协议(IP)地址时，无线电网络控制器节点(或通用重定向器节点)将其转发到毫微微无线电基站。在一些示例实施例中，毫微微无线电基站可使用系统信息的至少一部分和毫微微无线电基站的标识符，来从数据库中获得用于连接到毫微微无线电基站的适当无线电网络控制器节点的因特网协议(IP)地址。毫微微无线电基站的标识符可包括毫微微无线电基站的硬件标识符、毫微微无线电基站的序列号和毫微微无线电基站的拥有者/操作员编号中的至少一个。附图说明

为了便于说明而不是进行限制，以下描述中提出了诸如具体体系结构、接口、技术等的具体细节，以便透彻地了解本发明。然而，本领域的技术人员要清楚，也可在不同于这些具体细节的其它实施例中实施本发明。也就是说，虽然本文中没有进行明确地描述或表示，但本领域的技术人员能够设计各种方案，这些方案体现了本发明的原理，因此包含在它的精神和范围之内。在一些情况中，省略对众所周知的装置、电路及方法的详细描述，以免不必要的细节妨碍对本发明的描述。本文中描述本发明的原理、方面和实施例的所有陈述及其具体实例意在包含其结构以及功能的等效方案。另外，预计这类等效方案包括当前已知的等效方案以及将来开发的等效方案、即所开发的执行相同功能的任何单元，而与结构无关。
因此，例如，本领域的技术人员要理解，本文中的框图可以表示体现该技术的原理的说明性电路的概念视图。类似地，要理解，任何流程图、状态转移图、伪代码等表示实质上可通过计算机可读媒体所表示、因而由计算机或处理器所执行的各种过程，无论是否明确示出这种计算机或处理器。
包括标记为“处理器”或“控制器”的功能块的各种单元的功能可通过使用专用硬件以及能够与适当软件结合来运行软件的硬件来提供。在由处理器提供时，功能可由单个专用处理器、由单个共享处理器或者由其中一部分可以是共享或者分布式的多个独立处理器来提供。此外，术语“处理器”或“控制器”的明确使用不应当理解为专门表示能够运行软件的硬件，而是非限制性地可包括数字信号处理器(DSP)硬件、用于存储软件的只读存储器(ROM)、随机存取存储器(RAM)和非易失性存储装置。
在图1A所示电信系统10的非限制性示例上下文中来描述本发明。电信系统10连接到核心网络20。电信系统10包括无线电接入网24。无线电接入网24包括一个或多个无线电网络控制器节点(RNC)26和一个或多个无线电基站(BS)28。为了举例说明，图1A具体示出两个无线电网络控制器节点，即第一无线电网络控制节点261和第二无线电网络控制节点262，以及宏无线电基站(图1A中仅示出一个宏无线电基站28M)和多个毫微微无线电基站28f1、28f2、…28fx。宏无线电基站28M服务于宏小区CM。毫微微无线电基站28f1、28f2、…28fx服务于相应的毫微微小区Cf1、Cf2、…Cfx。本领域的技术人员理解，无线电基站通常位于无线电基站服务的相应小区内部(例如中心)，但是为了清楚起见，图1A的宏无线电基站和毫微微无线电基站示为通过双箭头关联到它们各自的小区。毫微微小区Cf1、Cf2、…Cfx中的至少一部分在地理上与宏小区CM重叠或被其覆盖。
本文所使用的“毫微微无线电基站”还具有服务于毫微微小区(或微微小区或者微小区)的微微无线电基站或微无线电基站的含义。毫微微小区通常与一个或多个宏小区重叠，并服务于比宏小区更小的地理区域或订户区。本文所述的技术对于可在无线电接入网中安装和/或重新定位而无需由无线电接入网的拥有者/操作员控制所述安装或重新定位的毫微微无线电基站极为有利。换言之，非网络运营商实体(毫微微操作员)可获得毫微微无线电基站，并按照毫微微操作员的偏好来设置毫微微无线电基站。在这方面，图1A正是示出刚由毫微微操作员激活的这样一种毫微微无线电基站28f-new。毫微微无线电基站28f-new在地理上设置或定位它的毫微微小区Cf-new，以便由宏小区CM覆盖。
用户设备单元(UE)、例如图1A所示的用户设备单元(UE)30通过无线电或空中接口32与一个或多个小区或者一个或多个基站(BS)28进行通信。用户设备单元可以是移动台，例如移动电话(“蜂窝”电话)和具有移动终端的膝上型计算机，因而例如可以是便携、袖珍、手持、计算机内置或者车载移动装置，它们与无线电接入网进行语音和/或数据通信。
作为非限制性实例，图1A所示的无线电接入网24可以是UMTS陆地无线电接入网(UTRAN)。在UTRAN中，无线电接入优选地基于宽带码分多址(WCDMA)，其中各个无线电信道使用CDMA扩频码来分配。当然也可使用其它接入方法。在UTRAN的实例方面，节点26和28分别称作无线电网络控制节点和无线电基站节点。但是，应当理解，对于其它类型的无线电接入网，术语“无线电网络控制”和“无线电基站”还包含具有相似功能性的节点。包含其它类型无线电接入网的其它类型电信系统包括：全球移动通信系统(GSM)；高级移动电话服务(AMPS)系统；窄带AMPS系统(NAMPS)；全接入通信系统(TACS)；个人数字蜂窝(PDC)系统；美国数字蜂窝(USDC)系统；以及EIA/TIA IS-95中描述的码分多址(CDMA)系统。
无线电接入网24通过接口、如UTRAN的Iu接口连接到核心网络20。图1A的核心网络20其中可包括移动交换中心(MSC)节点、网关MSC节点(GMSC)、网关通用分组无线业务(GPRS)支持节点(GGSN)和服务GPRS支持节点(SGSN)。电路交换(CS)网络或分组交换(PS)网络可连接到核心网络20。
为了简洁起见，图1A的无线电接入网24示为仅具有两个RNC节点26。可提供多个无线电网络控制器节点(RNC)，其中各RNC 26连接到一个或多个基站(BS)28。要理解，无线电网络控制26可为与图1A所示的不同数量的基站提供服务，并且RNC无需服务于相同数量的基站。此外，RNC可通过Iur接口连接到无线电接入网24中的一个或多个其它RNC。无线电网络控制器节点(RNC)26通过接口Iub与宏无线电基站28M进行通信。此外，本领域的技术人员还要理解，基站、如宏无线电基站28在本领域有时又称作无线电基站、节点B或者B节点。在图1A中由点划线示出各无线电接口32、Iu接口、Iur接口以及Iub接口。
在图1A中，毫微微无线电基站28f连接到通信网络38。这种通信网络的一个实例是IP网络38。
图1A还示出，无线电接入网24还包括域名系统(DNS)数据库42。域名系统(DNS)数据库42连接到IP网络38。远程单元域名系统(DNS)数据库42可作为无线电接入网24的独立节点来提供，如图所示，或者可以是另一个RAN节点的附件(例如包含在一个或多个无线电网络控制器节点(RNC)26中)。或者，在某些情况下，甚至可通过核心网络20提供对域名系统(DNS)数据库42的访问。
域名系统(DNS)数据库42被配置成当通过FQDN进行查询时，域名系统(DNS)数据库42返回与查询的FQDN对应的适当无线电网络控制器节点的因特网协议(IP)地址。
如图4中示出的一个示例格式所示，域名系统(DNS)数据库42存储用于将完全合格域名(FQDN)的一个或多个集合与特定无线电网络控制器节点关联的信息，使得在被询问时，可响应询问而返回与询问中包含的FQDN匹配的特定无线电网络控制器节点的IP网络地址。如下文所述，在这种询问和响应过程中，域名系统(DNS)数据库42向进行查询的毫微微无线电基站返回毫微微无线电基站应当连接并用作其活动无线电网络控制器节点的适当(例如最佳或优选)无线电网络控制器节点的地址。
图1A可看作是说明毫微微无线电基站28f-new对无线电接入网(RAN)、例如对其无线电网络控制器节点(如在具体示出的情况下为无线电网络控制器节点261)的通用接入。“通用接入”表示提供给毫微微无线电基站28f-new的接入可以是宽带固定接入或者宽带无线(移动)接入(如WiMAX)，如上所述。在宽带无线(移动)接入中，毫微微无线电基站28f-new对无线电接入网24的接入通过宏无线电基站进行，并且可使用例如高速下行链路分组接入(HSDPA)和增强上行链路、或WiMAX来进行。为了一般地适应接入类型，在图1A中，包括毫微微无线电基站28f-new的毫微微无线电基站28f连接到通信网络38。这种通信网络的一个实例是IP网络38。如果在上下文中没有明确说明，则本文所述技术的方面适用于所有类型的接入，包括宽带固定接入和宽带移动接入(例如宽带无线接入)。
图2示出一个示例通用毫微微无线电基站28f的所选基本典型的组成单元。毫微微无线电基站28f1、28f2、…28fx中的一个或多个可采取图2所示的通用毫微微无线电基站28f的形式。图2的毫微微无线电基站28f示为除了它的其它未示出组成单元以外还包括：IP接口单元50；一个或多个射频收发器52，射频接收器54；以及数据处理系统、部分或单元56。
射频收发器52用于通过无线电或空中接口与毫微微基站28f服务的毫微微小区中的用户设备单元(UE)通信。射频收发器52的数量取决于各种因素，包括毫微微无线电基站处理移动连接的能力。
在所示实施例中，接收器54常驻在毫微微无线电基站28f，并用于在毫微微无线电基站通过无线电接口来获取在无线电接入网24中广播的系统信息。例如，在一个示例实现中，毫微微无线电基站28f包括或配备了WCDMA接收器(UE)作为其射频接收器54，由此使毫微微无线电基站能够预占来自可接收小区(包括WCDMA宏小区和毫微微小区)的信号，并读取在那些小区中广播的相关系统或网络信息。在一个示例实现中，由覆盖毫微微小区的宏小区中的宏无线电基站广播的并由毫微微无线电基站接收的系统信息包括下列至少一个：(1)PLMN-ID；(2)位置区域代码(LAC)；以及(3)小区识别码(CI)。
因此，如上所述，在一个示例实施例中，毫微微无线电基站可配备例如WCDMA接收器或UE和USIM作为射频接收器54。如下所述，这个UE/USIM可用于连接到宏小区，宏小区然后提供移动宽带接入以便连接到RNC。
使用常驻接收器54只是毫微微无线电基站28f可获得系统或位置指示信息(系统或位置指示信息用于至少部分构成FQDN)的一种示例方式。本文所述的技术，并且具体包括在毫微微无线电基站构成/使用FQDN以便询问域名系统(DNS)数据库，适用于毫微微无线电基站没有常驻接收器而必须例如从毫微微无线电基站服务的用户设备单元外部获取系统或位置指示信息的其它实施例。
RBS数据处理系统56包括FQDN构成单元58。如本文所述，FQDN构成单元58至少部分使用该系统信息或者(例如由射频接收器54获取的)系统信息来构造完全合格域名(FQDN)。FQDN构成单元58可作为所示RBS数据处理系统56的组成部分包含在内，或者在前面所述那些方面的广义上，作为不同的控制器或处理器来提供。
图3示出一个示例无线电网络控制节点26的所选基本典型的组成单元。无线电网络控制节点26可包括若干接口单元，例如：接口单元70，用于通过Iu接口将无线电网络控制节点26连接到核心网络20；接口单元72，用于通过Iur接口将无线电网络控制节点26连接到其它(未示出)无线电网络控制器；一个或多个接口单元74，用于通过Iub接口将无线电网络控制节点26连接到相应的一个或多个宏无线电基站28M；以及一个或多个接口单元76，用于将无线电网络控制节点26连接到相应的一个或多个毫微微无线电基站28f1、28f2、…28fx。RNC 26与毫微微无线电基站28M之间的连接可通过通信网络38进行，并且可使用例如基于因特网协议(IP)的传输。RNC 26与宏无线电基站28M之间的连接可使用例如基于因特网协议(IP)和/或基于ATM的传输。
除了接口单元之外，无线电网络控制节点26还包括许多未示出的组成单元，以及数据处理系统、部分或单元80。如图3所示，在一个非限制性示例实现中，无线电网络控制节点26的数据处理系统80包括：控制部分(例如控制器82)；切换单元84；以及组合器和分离器单元86(例如在处理连接的多样分支中所涉及的)。
在图1A所示的时间，毫微微无线电基站28f-new刚由毫微微操作员激活。紧接在激活后，毫微微无线电基站28f-new(如事件或步骤S-1A所示)仍然不知道它在无线电接入网24环境中的具体位置，因而不知道哪一个无线电网络控制器节点26最佳设置(在地理上或在其它方面)用作毫微微无线电基站28f-new的活动无线电网络控制节点。在图1A所示的情况下，毫微微无线电基站28f-new位于由无线电基站26M和第二无线电网络控制器节点262提供服务的宏小区CM中。因此，从无线电接入网24的拓扑结构来判断，毫微微无线电基站28f-new的正确/优选无线电网络控制节点是第二无线电网络控制器节点262，而不是第一无线电网络控制器节点261。
鉴于它对自己在无线电接入网24中的情况不了解，毫微微无线电基站28f-new激活它的射频接收器54，并使用射频接收器54通过无线电接口来确定或获取在无线电接入网24中广播的系统信息。在这方面，图1B作为事件或步骤S-1B示出系统信息的获取。
系统信息(又称作位置指示信息)可包含下列一个或多个：(1)PLMN-ID；(2)位置区域代码(LAC)；以及(3)小区识别码(CI)。PLMN-ID可从主信息块(MIB)解码。位置区域代码(LAC)可从解码系统信息块1(SIB 1)解码。小区识别码(CI)可从系统信息块3(SIB 3)解码。UTRAN小区识别码由28位组成，并且这些位中的12位通常用来包含RNC标识符。这意味着，在这些情况下，小区识别码(CI)可用来标识一个PLMN中的RNC。
图1C示出，作为事件或步骤S-1C，毫微微无线电基站28f-new使用系统信息的至少一部分来构造完全合格域名(FQDN)。完全合格域名(FQDN)的构造由毫微微无线电基站28f-new的FQDN构成单元58执行。
因此，在射频接收器54已经搜索周围宏覆盖区并预占允许包括射频接收器54的UE使用的最佳UTRAN小区之后，USIM信息可用来查明允许哪些PLMN。UE如射频接收器54读取相关系统信息，该相关系统信息被传送给FQDN构成单元58。然后，FQDN构成单元58至少部分根据系统信息来构造完全合格域名(FQDN)。
一旦(例如以随后描述的方式)构造了完全合格域名(FQDN)，如图1D所示，毫微微无线电基站就使用完全合格域名(FQDN)来询问域名系统(DNS)数据库42。在毫微微无线电基站28f-new的一个示例实现中，将完全合格域名(FQDN)作为节点地址查询传送到IP接口单元50，如图1D中的步骤或事件S-1D所示。IP接口单元50用于向域名系统(DNS)数据库42发送包含完全合格域名(FQDN)的节点地址查询。为了访问域名系统(DNS)数据库42，毫微微无线电基站28f-new预先知道域名系统(DNS)数据库42的网络地址，例如，使用例如动态主机配置协议(DHCP)服务器将域名系统(DNS)数据库42的网络地址预先存储或预先下载到IP接口单元50。作为一个实例，图2将毫微微无线电基站28f示为具有用于存储域名系统(DNS)数据库42的IP地址的存储器94(优选为非易失性的)。
图1E示出，作为步骤或事件S-1E，域名系统(DNS)数据库42从毫微微无线电基站28f-new接收节点地址查询(询问)，并执行搜索以便将适当或正确的无线电网络控制器节点的IP地址与询问的FQDN进行匹配。如图4所示，在域名系统(DNS)数据库42的一个示例配置中，无线电网络控制器节点的IP地址可能与几个查询、例如与几个完全合格域名(FQDN)关联。
图1E还示出，域名系统(DNS)数据库42向毫微微无线电基站28f-new返回响应，该响应以与询问的FQDN匹配或适当对应的适当或正确无线电网络控制器节点IP地址的形式。毫微微无线电基站28f-new的IP接口单元50用于接收对询问的响应(适当/正确无线电网络控制器节点的因特网协议(IP)地址)。适当/正确无线电网络控制器节点的因特网协议(IP)地址可存储在存储器或寄存器、如图2所示的存储器96中。
图1F示出，作为操作的下一个阶段，毫微微无线电基站28f-new、具体来说是它的IP接口单元50使用适当/正确无线电网络控制器节点的因特网协议(IP)地址(通过以上参照图1A-图1E所述的方式获得的)连接到由毫微微无线电基站用作该毫微微无线电基站的活动无线电网络控制节点的适当/正确无线电网络控制器节点。在图1F所示的具体情况下，IP接口单元50通过IP网络38连接到第二无线电网络控制器节点262，由网络拓扑结构来看，第二无线电网络控制器节点262是毫微微无线电基站28f-new的正确/优选无线电网络控制节点。通过IP网络38连接到无线电网络控制器节点262如图1F中的步骤或事件S-1F所示。
因此，在以上所述的示例方式中，由FQDN构成单元58形成的FQDN用来询问域名系统(DNS)数据库42，以便查找正确RNC的IP地址。这使毫微微无线电基站28f-new能够发起与域名系统(DNS)数据库42选取地址的无线电网络控制器节点的IP连接。
在图1A-图1F的实施例和模式中，由FQDN构成单元58形成的FQDN用于直接询问域名系统(DNS)数据库42，以便查找正确RNC的IP地址。图6示出另一个实施例和模式，其中将FQDN构成单元58形成的FQDN作为节点地址查询发送到无线电网络控制器节点，然后无线电网络控制器节点查询数据库、如域名服务器(DNS)数据库42(6)。在图6的实施例中，毫微微无线电基站28f的接口50通过称作“扩展Iub”接口(“Iub+”接口)的接口连接到通信网络38。扩展Iub+接口优选地由通过IP网络38的因特网协议(IP)连接形成。在一些实现中，Iub+接口类似于Iub接口，但对于传送附加信息进行了修改。图6实施例和模式的操作以实质上与图1A-图1F的实施例和模式中的图1A-图1C所示相同的方式开始。但是，与先前的示例实施例相比，对于图6的实施例和模式，步骤S-6D(1)示出，毫微微无线电基站28f的IP接口单元50向无线电网络控制器节点261发送包含完全合格域名(FQDN)的询问。无线电网络控制器节点261可以是缺省RNC节点，它的网络地址是毫微微无线电基站28f预先知道的(例如在毫微微无线电基站28f预先配置的)。步骤S-6D(2)示出，无线电网络控制器节点261用包含毫微微无线电基站28f形成的完全合格域名(FQDN)的询问来查询域名服务器(DNS)数据库42(6)。在图6所示的具体示例实施例中，域名服务器(DNS)数据库42(6)设置在不同于无线电网络控制器节点261的节点的另一个节点。但是，在其它实施例中，域名服务器(DNS)数据库42(6)可与缺省无线电网络控制器节点261位于同一地点。
图6还示出，作为步骤或事件S-6E(1)，域名系统(DNS)数据库42从无线电网络控制器节点261接收询问，并执行搜索以便将适当或正确的无线电网络控制器节点的IP地址与询问的FQDN进行匹配。图6还示出，作为步骤或事件S-6E(2)，域名系统(DNS)数据库42向无线电网络控制器节点261返回响应，该响应以与询问的FQDN匹配或适当对应的适当或正确无线电网络控制器节点IP地址的形式。作为步骤或事件S-6E(3)，无线电网络控制器节点261向毫微微无线电基站28f-new的IP接口单元50转发来自域名服务器(DNS)数据库42(6)的响应。因此，毫微微无线电基站28f-new的IP接口单元50用于接收对询问的响应(适当/正确无线电网络控制器节点的因特网协议(IP)地址)。如前面所述，适当/正确无线电网络控制器节点的因特网协议(IP)地址可存储在毫微微无线电基站28f的存储器或寄存器中。在图6的示例实施例和模式中，结果是无线电网络控制器节点262而不是无线电网络控制器节点261作为毫微微无线电基站28f的适当/正确无线电网络控制器节点。
然后，作为步骤或事件S-6F所示操作的下一个阶段，毫微微无线电基站28f-new、具体来说是它的IP接口单元50使用适当/正确无线电网络控制器节点的因特网协议(IP)地址连接到由毫微微无线电基站用作该毫微微无线电基站的活动无线电网络控制节点的适当/正确无线电网络控制器节点。在图1F所示的具体情况下，IP接口单元50通过IP网络38连接到第二无线电网络控制器节点262，由网络拓扑结构来看，第二无线电网络控制器节点262是毫微微无线电基站28f-new的正确/优选无线电网络控制节点。通过IP网络38到无线电网络控制器节点262的连接如图6中的步骤或事件S-6F所示。
因此，在图6的实施例和模式中，毫微微无线电基站28f与它的缺省无线电网络控制器节点261之间的Iub+接口类似于Iub接口，但对于传送附加信息、例如步骤S-6C的询问和步骤S-6D(3)的响应进行了修改。
图7的实施例和模式与图6的相似，但包括通用重定向器节点100。通用重定向器节点100执行图6的无线电网络控制器节点261的相似步骤和功能，但使用通过“重定向”接口的“重定向”协议而不是扩展的Iub即Iub+协议。“重定向”协议可以是配置成向通用节点传送例如询问信息和响应的任何新协议。因此，图7将通用重定向器节点100示为，作为步骤或事件S-7D(2)将询问转发到域名服务器(DNS)数据库42(7)，作为步骤或事件S-7E(2)从域名服务器(DNS)数据库42(7)接收响应，以及作为步骤或事件S-7E(3)向毫微微无线电基站28f转发来自域名服务器(DNS)数据库42(7)的响应。然后，作为步骤或事件S-7F所示操作的下一个阶段，毫微微无线电基站28f-new、具体来说是它的IP接口单元50使用适当/正确无线电网络控制器节点(例如图7实例中是无线电网络控制器节点262)的因特网协议(IP)地址连接到由毫微微无线电基站用作该毫微微无线电基站的活动无线电网络控制节点的适当/正确无线电网络控制器节点。
在它们相应的图6和图7实施例中，缺省无线电网络控制器节点261和通用重定向器节点100可联系设置在另一个节点的域名服务器(DNS)数据库，分别如图6和图7所示情况中那样。或者，在它们相应的实施例中，缺省无线电网络控制器节点261和通用重定向器节点100本身可执行域名服务器(DNS)数据库的功能。
此外，应当知道，在本文所述实施例的任一个中被查询的数据库不一定需要专门称作或用作域名服务器(DNS)数据库。而是可采用具有定位或者确定毫微微无线电基站的正确或适当无线电网络控制器节点地址的充分信息的任何其它数据库。
如上所述，FQDN构成单元58至少部分根据系统信息来构造完全合格域名(FQDN)。在例如完全合格域名(FQDN)还可基于在毫微微无线电基站中标识运营商的预先配置信息的意义上，完全合格域名(FQDN)被说成是至少部分基于系统信息。预先配置信息例如可能是如“operator.com”等的字符串。这个具体标识符在以下FQDN的实例中称作“pre-conf-oeprator-id”。在一些其它情况下，毫微微无线电基站可改用字符串“.pub.3gppnetwork.org”作为预先配置标识符。
如下文所述，至少部分使用广播系统信息的至少一部分来构成的完全合格域名(FQDN)可通过各种不同方式来构成或生成。在一个示例实现中，构建完全合格域名(FQDN)的一种方式是使用所有三个标识符：PLMN-ID、LAC和小区识别码。作为另一个实例，完全合格域名(FQDN)可包括下列中的两个或更多个的几部分的组合：(1)PLMN-ID；(2)位置区域代码(LAC)；以及(3)小区识别码(CI)，这种组合有可能是下列中的两个或更多个的几部分的并置：(1)PLMN-ID；(2)位置区域代码(LAC)；以及(3)小区识别码(CI)。
因此，实质上，PLMN-ID、LAC和CI的任何组合都可用来构造FQDN。下面列出示例组合(记住，“pre-conf-operator-id”表示预先配置信息)：·PLMN-ID、LAC和小区识别码(CI)·PLMN-ID和LAC·PLMN-ID和小区识别码·只有pre-conf-operator-id和LAC(在某些情况下)·只有pre-conf-operator-id和小区识别码(在某些情况下)
对于一种示例情况，考虑通过以下信息描述的UTRAN环境的情况：·毫微微无线电基站的预先配置信息、即pre-conf-operator-id设置为“operator.com”·PLMN-ID为012-123(即移动国家代码MCC为012，并且移动网络代码MNC为123)·LAC的值为34567·CI的值为H’123 4567(这意味着CI的RNC标识符部分为H’123(即十进制291)，并且3G小区识别码部分为H’4567(即十进制17767))
在上面刚描述的情况中，下面是对于该情况可由FQDN构成单元58构成或生成的完全合格域名(FQDN)的非限制性实例列表：
Figure G39798778150131000D000201
只有pre-conf-operator-id和小区识别码的RNC部分，例如“rnc291.operator.com”
Figure G39798778150131000D000202
只有pre-conf-operator-id和LAC(在某些情况下)，例如“lac34567.operator.com”
Figure G39798778150131000D000203
PLMN-ID和LAC，例如“lac34567.mnc123.mcc012.pub.3gppnetwork.org”
在操作的一种示例模式中，毫微微操作员可选择一种或多种不同的备选方式来构造FQDN。域名系统(DNS)数据库42应当被编程或更新为反映域名系统(DNS)数据库42负责的所有无线电网络控制器节点的相关信息(IP地址和FQDN匹配或配对)。
如果毫微微无线电基站没在WCDMA覆盖范围，则在一个示例实施例中，毫微微无线电基站可仅使用pre-conf-operator-id连接到域名系统(DNS)数据库42。这样一种毫微微无线电基站可连接到任何无线电网络控制器节点、如缺省或中心RNC，因为在这种情况下，无需提供相邻小区列表，因为切换和漫游到宏小区不可能没有释放覆盖范围。
此外，在一些实施例和模式中，节点地址查询可采取与完全合格域名(FQDN)不同的形式。例如，在图8和图9的示例实施例和模式中，节点地址查询采取节点地址请求消息的形式，(在图8)其被发送到无线电网络控制器节点261，或者(在图9)其被发送到通用重定向器节点。图8的示例步骤或事件与图6的相似，要理解，在图8中，节点地址查询采取节点地址消息的形式而不是完全合格域名(FQDN)的形式，并且数据库42(8)不一定必须是域名服务器(DNS)数据库。类似地，图9的示例步骤或事件与图7的相似，还要理解，在图9中，节点地址查询采取节点地址消息的形式而不是完全合格域名(FQDN)的形式，并且数据库42(9)不一定必须是域名服务器(DNS)数据库。
节点地址请求消息可包括系统信息的至少一部分和毫微微无线电基站的标识符中的之一或二者，以从数据库中获得适当无线电网络控制器节点的因特网协议(IP)地址。在不同的实现中，节点地址请求消息中使用的毫微微无线电基站的标识符可包括毫微微无线电基站的硬件标识符、毫微微无线电基站的序列号和毫微微无线电基站的拥有者/操作员编号中的至少一个。数据库(例如数据库42(8)或数据库42(9))可使用系统信息和标识符中之一或二者来确定承载该标识符并提供该系统信息的毫微微无线电基站的适当无线电网络控制器节点。
不管节点地址查询可采取什么形式(例如无论FQDN还是节点地址请求消息)，无论什么无线电网络控制器节点成为毫微微无线电基站28f-new的活动无线电网络控制器节点，都还应能够在环境有需要时将毫微微RBS重定向到另一个RNC。这种重定向可包括进一步查询数据库42。这个判定可(例如)基于经由毫微微无线电基站产生的业务量和类型。
如上所述，在激活和启动时，毫微微无线电基站28f-new实质上不知道它在无线电接入网中的具体位置。因此，在毫微微无线电基站28f-new构造节点地址查询(例如完全合格域名(FQDN)或节点地址请求消息)并执行适当数据库42的询问时的目的是，使得毫微微无线电基站28f-new可获悉毫微微无线电基站可连接的用作活动无线电网络控制器节点的适当或正确无线电网络控制器节点的地址。
因此，如上所述，毫微微无线电基站可由终端用户移动，并且毫微微无线电基站仍将使用上述技术连接到正确的RNC。
上述原理/方法还可适用于与WCDMA不同的无线电技术，WCDMA仅作为一个实例来说明。其它适当的技术包括但不限于GSM、CDMA、WiMAX等。该技术具体与上述和适当描述的系统及情况相关，但也可适用于其它情况以及其它网络。
虽然已经详细说明和描述了本发明的各种实施例，但权利要求书不限于任何具体实施例或实例。以上描述不应当被理解为表示任何具体单元、步骤、范围或功能是绝对必要的。本发明不是要限制到所公开的实施例，而是意在涵盖各种修改和等效配置。
