家庭网絡控制器(Domestic Network Controller, 筒称 DNC ) 104, 功能 类似于无线网络控制器(RNC ) , 支持 DNC/Home NodeB的特有功能, 这 里的特有功能是指 Home NodeB 101向 DNC 104上报含有无线环境信息的扫 描报告, DNC 104根据 Home NodeB 101上报的无线环境信息为 Home NodeB 101分配载频, 扰码, 邻区列表, 达到通讯网络的自适应, 无需在 DNC 104 再为 Home NodeB 101手工配置载频, 扰码, 邻区列表信息。
安全网关 (SGW) 105, 其 IP地址预先配置并保存在 Home NodeB 101 中, 在 Home NodeB和 DNC通讯网络之间, 以及 Home NodeB和 HCS操作 维护网络之间提供 Ipsec隧道, 保证网络接入的安全性, 同时担当对 Home NodeB鉴权, 为 Home NodeB分配虚拟专用网络 ( Virtual Private Network, 简称 VPN ) IP。
图 2示出了本发明系统在实现时的一个具体的应用实例,就本自组织网 络中各网絡设备的功能介绍,以及各网絡设备之间的功能交互来阐述本自組 织网络如何达到 Home NodeB操作维护管理和通讯业务的自组织和自适应。 本系统应用实例中 Home NodeB经 IP网络连接到 SGW, 其中 SGW根据连 接关系, 分为与 DNC连接的 DNC侧安全网关 ( SGW-DNC ) , 与 HCS相 连的 HCS侧安全网关 (SGW-HCS ) 。 在本应用实例当中, 有两个 DNC, 分别为 DNC1和 DNC2, 与 DNC1相连的为 SGW-DNC1 , 与 DNC2相连的 为 SGW-DNC2。 而且, SGW-HCS除了连接到 HCS之外,还与 SGW-DNC1 和 SGW-DNC2—起, 连接到鉴权 /授权 /计费服务器(AAA Server ) , 为系统 提供鉴权功能,提供鉴权功能所需要的信息均从 HCS获取。 DNC1和 DNC2 均分別与服务 GPRS支持节点(SGSN )、 移动业务交换中心(MSC )相连。
HCS与 AAA Server, 均通过 MAP网关连接到归属位置寄存器 (HLR ) 。
DNC1、 DNC2 、 HCS以及 AAA Server, 均连接到数据同步接口 /IP。
在图 2所示的本应用实例当中:
Home NodeB与 SGW之间为建立安全通道的 Ipsec/WAN接口, 也即 Home NodeB与 SGW-HCS、 SGW-DNC1和 SGW-DNC2之间采用 Ipsec/WAN 接口, 支持 Ipsec及其相关协议, 而且与 SGW-HCS的 Ipsec通道建立采用互 联网密钥交换版本 2 ( Internet Key Exchange version 2, 简称 IKEv2 ) 的可扩 展认证协议 ( Extensible Authentication Protocol, 简称 EAP ) -认证与密钥分 发协议 ( Authentication Key Agreement Protocol , 简称 ΑΚΑ ) , 提供了安全 接入以及对 Home NodeB鉴权的功能,即该 Home NodeB是否归属于需要接 入的 HCS和 DNC,并且为 Home NodeB分配 VPN IP(信息来自 AAA server ), 为 HCS , DNC和 Home NodeB之间的交互过程提供安全的网络。
Home NodeB与 DNC1之间, 采用的是 Iub扩展接口, 基于 Iu接口, 支 持 Home NodeB通过 Iub口向 DNC上艮无线环境信息, 同时支持 DNC根据 Home NodeB上报的无线环境信息通过 Iub口为 Home NodeB分配载频, 扰 码, 邻区列表, 达到通讯网络的自适应。 Home NodeB与 DNC2之间, 采用 的也是 Iub扩展接口。
Home NodeB从 HCS获取配置信息( 置信息包括 Home NodeB 标识, SGW-DNC和 DNC的 IP地址和端口, Home NodeB候选载频, Home NodeB 最大发射功率输出, Home NodeB组号)和版本信息, 运行版本文件; 通过 这些配置信息, Home NodeB可以完成对 DNC的接入, 以及 Home NodeB 的自安装, 自配置, 以及软件自动更新; Home NodeB每次上电时自动从 HCS获取配置信息, 版本信息, 版本校验, 版本更新等, 无须用户干涉。
SGW与 AAA Server之间的接口为 Radius接口, 也即 SGW-DNC1、 SGW-DNC2和 SGW-HCS从 AAA Server获取 Home NodeB鉴权信息和 Home NodeB的 IP地址, 鉴权包括 Home NodeB接入 HCS 的鉴权, Home NodeB 接入 DNC的鉴权。 AAA Server,提供 Home NodeB鉴权信息和 Home NodeB 的 IP地址, 并提供 EAP/AKA协议的相关流程。
HCS对 Home NodeB提供自安装, 自配置,软件自动更新等服务, Home
NodeB每次上电时自动从 HCS请求配置信息,版本信息, HCS在收到 Home NodeB的请求后, 为其提供配置信息, 版本信息等, 无须用户干涉; Home NodeB配置信息的更改, 维护,版本的更新均在 HCS进行。 HCS作为 Home NodeB自组织网络的数据管理中心,可以将自组织网络中其它设备需要的数 据均放置于 HCS进行配置和维护, 并扩展和其它设备的接口, 使得数据统 一维护, 统一更新, 比如: 为 DNC提供需要的 Home NodeB信息, 包括归 属于本 DNC的 Home NodeB ID; Home NodeB可接入的国际移动用户识别 码(IMSI ) ;从 HLR获取归属于 Home NodeB的 IMSI和国际移动用户 ISDN 号码( MSISDN ),用于通知 Home NodeB归属的 DNC其属下的 Home NodeB 可接入的合法用户列表; 作为数据配置中心, 集中管理所有 Home NodeB的 信息, Home NodeB的鉴权信息同样也在 HCS配置, AAA server提供鉴权 功能需要的信息均从 HCS获取。
DNC DNC2与 SGSN、 MSC之间,采用 Iu标准接口; DNC1和 DNC2 从 HCS获得 Home NodeB相关信息,包括归属于本 DNC的 Home NodeB ID, Home NodeB可接入的 IMSI, 在用户从某 Home NodeB发起呼叫时,检测该 用户是否属于 Home NodeB的合法用户, 如果不合法, 则拒绝接入, 简化用 户呼叫的鉴权过程。
MAP网关与 HLR之间, 采用 MAP/No.7信令接口。
图 3示出了本发明自组织网络方法实施例的步骤, Home NodeB完成自 组织的过程如下:
步骤 301, Home NodeB上电自检测, 并预先配置静态数据, 这部分静 态数据包括 SGW和 HCS的地址(域名 ) ;
步驟 302, Home NodeB和 SGW之间建立 IPsec通道, SGW为 Home NodeB分配 VPN IP地址, IPsec过程包括鉴权和加密,鉴权协议采用 IKEv2; 步骤 303 , Home NodeB向 HCS发起请求, 请求获取配置数据信息和版 本信息,版本相符之后根据配置数据信息完成系统参数配置, 达到操作维护 的自适应目的, 获取的动态数据包括: DNC的 IP地址和端口, SGW的 IP 地址和端口; Home NodeB运行版本号, 版本文件; Home NodeB候选载频; Home NodeB最大发射功率输出; Home NodeB组号等;
步驟 304, HCS作为数据配置中心, 对 Home NodeB的数据进行集中管 理, 集中管理的数据包括: DNC的 IP地址和端口, SGW的 IP地址和端口; Home NodeB的 VPN IP地址; Home NodeB版本信息,版本文件; Home NodeB 鉴权信息, 例如 Home NodeB ID; Home NodeB加密信息, 例如密钥参数和 算法; Home NodeB候选载频列表; Home NodeB用户信息, 包括用户名, 用户地址, 用户联系方式; Home NodeB最大发射功率输出等;
步骤 305 , Home NodeB 扫描邻接小区信息并形成扫描报告, Home NodeB根据从 HCS获取的载频列表扫描所有载频列表范围内的邻区信息, 通过读取邻区的公共导频信道(CPICH ) , 辅助信道(SCH ) 和广播信道 ( BCH ) , 形成扫描报告, 扫描报告的内容包括检测到的小区标识(ID ) , 每个小区的载频, 每个小区的公众陆地移动网 ( PLMN ) , 每个小区的接收 信号强度指示(RSSI ) , 每个小区的扰码, 如果 Home NodeB位于没有通用 移动通信系统(UMTS )信号的区域, 则其扫描^ :艮告为空;
步骤 306, Home NodeB将邻接小区信息形成的扫描报告发送给 DNC; 步骤 307, DNC根据 Home NodeB上报的邻接小区信息为 Home NodeB 选择载频, 扰码, 以及 Home NodeB邻接小区列表, 达到通讯业务的自适应 目的; 在载频的选择策略上可以采用选择空闲的或取 RSSI最低载频, 在扰 码的选择策略上可以选择同一载频中和其它小区冲突最少的;在邻区的选择 上, 分两种情况, 一种是 Home NodeB作为家庭模式使用则 DNC配置 RSSI 相对较高的公共 UMTS小区作为其邻接小区, 一种是 Home NodeB从属于 某组的模式则将其同组的其他 Home NodeB小区作为其邻接小区。
步骤 308, 自组织网络建立完毕, 进入正常的通讯业务流程。
上述步骤 303中的 Home NodeB组号,用于区分 Home NodeB是否从属 于某个组以及从属于哪个组, 如果 Home NodeB 用于家庭或者作为独立 Home NodeB,则组号配置为 0,如果 Home NodeB从属于某个组且组号为 n, 则 DNC将配置同一组号内的其它 Home NodeB小区作为其邻接小区。
从以上实施例来看, Home NodeB能够基于全 IP网络完成自动安装, 自 动配置, 提供通讯业务, 并且保证足够的安全性, 其核心是: Home NodeB 在上电后, 接入操作维护网络和通讯业务网络, 自动完成数据配置, 软件安
装,软件更新,接入通讯业务网络后, 自适应进行网络规划,提供通讯业务。 本发明提出的技术方案同时具备操作维护网络和通讯业务网络的自组织特 性, 特别适合 Home NodeB这样操作维护难、 网络规划难的无线接入设备。

步驟 406, AAA Server对 Home NodeB 进行鉴权, 所采用的协议为 IKEv2, 并对鉴权结果进行加密, 形成鉴权结果信息发送给 SGW-HCS; 步骤 407, SGW-HCS根据鉴权结果信息, 如果 AAA Server鉴权成功, 则进行步骤 408,否则向 Home NodeB返回拒绝接入的信息(如图中标记 4080 所示) ;
步骤 408 , SGW-HCS为 Home NodeB分配 VPN IP地址,与 Home NodeB 建立 IPsec通道;

步驟 413 , Home NodeB根据得到的配置数据完成系统的参数配置, 扫 描邻接小区信息并形成扫描报告;
步驟 414, Home NodeB向 SGW-DNC发送 IPsec通道建立请求, 请求 建立 IPsec通道;
