Description

一种家庭基站的共享方法和家庭基站系统
技术领域
本发明涉及一种家庭基站的共享方法和家庭基站系统。
背景技术
家庭基站是一种小型、低功率的基站, 部署在家庭及办公室等室内场所, 主要的作用是为用户提供更高的业务速率并降低使用高速率服务所需要的费 用, 同时弥补分布式蜂窝无线通信系统覆盖的不足。 家庭基站的优点是便捷、 输出功率低、 即插即用等。
家庭基站系统几乎可以应用于所有的移动通信网络中, 比如第三代合作 伙伴计划 2 ( 3rd Generation Partnership Project 2, 简称为 3GPP2 ) 中釆用码分 多址( Code Division Multiple Access, 简称 CDMA ) 系列标准的 CDMA1X和 CDMA2000 网络, 以及第三代合作伙伴计划 (3rd Generation Partnership Project, 简称为 3GPP ) 中的全球移动通讯系统 (Global System for Mobile Communications, 简称 GSM )等 2G ( 2nd Generation, 第二代) 网络, 宽带 CDMA系统 ( Wideband Code Division Multiple Access , 简称 WCDMA ) 系 统等 3G ( 3 Generation, 第三代) 网络, 以及未来几乎所有运营商网络都将 选择采用的全互联网协议(Internet Protocol, 简称 IP ) 的 LTE ( Long Term Evolution, 长期演进)移动通信网络, 还有与 LTE采用几乎相同的调制技术 的! ¾波接入全求互通 ( Worldwide Interoperability for Microwave Access, 简称 为 WiMAX )移动通信网络。
图 1是现有家庭基站系统的结构示意图。
如图 1所示,用户终端( User Equipment,简称 UE )可以通过宏蜂窝( Macro Cell ) 网络接入到核心网 ( Core Network, 简称 CN ) , 执行相应的语音业务, 也可以通过访问 Internet (互联网 )执行数据业务。
然而为了解决家庭室内网络的覆盖, UE 还可以通过家庭基站接入点 ( Femto AP )接入到 IP回程网絡中, 通过 IP回程网络接入到服务地的家庭 基站网关(Femto GW )上, 然后接入到服务地的核心网, 再通过核心网访问 Internet
在 Femto AP和服务地的 Femto GW (简称服务 Femto GW )之间可以设 置服务地的安全网关 ( Security Gateway, 简称 SeGW ) , Femto AP通过服务 地的安全网关 (简称服务 SeGW、 或服务安全网关)建立与服务 Femto GW 之间的 IP安全隧道。
月 II务地的 Femto 认证系统 ( Authentication, Authorization and Accounting, 简称 AAA ) 与服务安全网关相连, 协助 Femto AP与服务安全网关建立 IP安 全隧道。
服务地的家庭基站管理服务器 ( Femto Management Server, 筒称 FMS ) 通过服务安全网关与 Femto AP相连,用于配置 Femto AP的参数,保证 Femto AP的正常运行。 Femto AP与服务地的家庭基站管理服务器 (简称服务 FMS ) 采用宽带论坛的家庭网络协议 TR069协议进行参数的配置。
Femto AP也可以直接接入到 Internet 另外根据不同的网关类型, Femto GW可以接入三种核心网, 分别为: 电路交换( Circuit Switched, 简称 CS ) 网络, IP多媒体子系统 ( IP Multimedia Core Network Subsystem, 简称 IMS ) 网络和包交换( Packet Switched, 简称 PS ) 网絡。
由于 Wimax和 LTE网络都是全 IP网络,因此通过 Wimax和 LTE网络的 家庭基站接入核心网都是通过 IP网络接入的, 因此 Femto GW在实际部署中 是可以不需要。
以上主要对图 1 中的服务地网元进行了介绍, 服务地网元是最终为用户 设备提供服务的网元。 在完成初始化前, Femto AP中保存的是初始地网元的 相关参数, 例如, 初始地的安全网关(简称为初始 SeGW或初始安全网关)、 初始地的 Femto认证系统(简称为初始 Femto AAA )和初始地的家庭基站管 理服务器 (简称为初始 FMS ) 的相关参数, 上述初始地网元用于在初始化过 程中发现服务地网元(具体流程可参见图 2 ) 。
此外, 图 1 中的各艮务地网元可以与初始地网元为相同的网元, 即 ϋ良务 地与初始地相同。 图 2是现有技术中 Femto AP的初始化方法流程图 ,在该流程中 Femto AP 获取到服务地的家庭基站网关(简称服务 Femto GW )的相关信息, 并完成了 参数配置。 如图 2所示, 该流程包括如下步骤:
201 , Femto AP与初始 SeGW建立 IP安全隧道;
在 Femto AP与初始 SeGW建立 IP安全隧道时, 需要初始 Femto AAA对
Femto AP进行认证, 具体流程可参考相关文档。
202, Femto AP通过建立的 IP安全隧道向初始 FMS发送 TR069信息请 求消息, 该消息中携带 Femto AP的标识、 位置信息和初始化标识等参数;
203 ,初始 FMS对 Femto AP的接入权限进行认证,认证成功后,向 Femto AP返回 TR069信息请求响应消息;
204 , 初始 FMS向 Femto AP发送 TR069设置参数请求消息, 该消息中 携带服务 FMS列表(例如, 服务 FMS的 IP地址列表) ; 该消息中还可携带 服务 SeGW列表(例如, 服务 SeGW的 IP地址列表) , 用于在 Femto AP与 服务 FMS之间建立新的 IP安全隧道;此外,该消息还可以携带服务 Femto GW 列表(例如, 服务 Femto GW的 IP地址列表) ;
205 , Femto AP确认初始 FMS发送的信息, 根据该信息选择服务 FMS、 服务 SeGW和服务 Femto GW后, 向初始 FMS回送 TR069设置参数响应消 息;
206,如果服务 SeGW与初始 SeGW不同,则释放 Femto AP与初始 SeGW 之间的 IP安全隧道;
如杲服务 SeGW就是初始 SeGW, 就不需要在 Femto AP与 SeGW之间 重建 IP安全隧道, 当然也就不需要释放 Femto AP与初始 SeGW之间的 IP安 全隧道。
207, 如果服务 SeGW与初始 SeGW不同, Femto AP建立与服务 SeGW 之间的 IP安全隧道;
在与服务 SeGW建立 IP安全隧道时, 需要服务 Femto AAA对 Femto AP 进行认证, 具体流程可参考相关文档。
208, Femto AP通过建立的 IP安全隧道向服务 FMS发送 TR069信息请 求消息, 该消息中携带 Femto AP的标识, 告警标识, 位置信息和初始化标识 等参数;
209,服务 FMS对 Femto AP的接入权限进行认证,认证成功后,向 Femto AP返回 TR069信息请求响应消息;
210, 服务 FMS向 Femto AP发送 TR069设置参数请求消息, 该消息中 携带: 与服务 Femto GW相关的服务 SeGW列表、 Femto AP的配置参数和鉴 权参数;
此外 , 如果步骤 204的 TR069设置参数请求消息中没有携带服务 Femto GW列表, 则本步骤的 TR069设置参数请求消息中还需携带服务 Femto GW 列表。
211 , Femto AP确认服务 FMS发送的信息, 根据该信息选择服务 SeGW 和服务 Femto GW后, 向服务 FMS回送 TR069设置参数响应消息;
212,如果步骤 211中选择的服务 SeGW与步骤 205中选择的服务 SeGW 不同, 则 Femto AP释放步骤 207中建立的 IP安全隧道。
图 3是现有技术中 Femto AP的注册方法流程图, 具体包括如下步骤:
301 , Femto AP采用图 2所示流程从 FMS获取配置参数以及服务 Femto GW信息;
302, Femto AP与服务 SeGW建立 IP安全隧道;
如果在图 2所示的初始化流程中, 步骤 211中选择的服务 SeGW与步骤 205中选择的服务 SeGW相同, 则由于在步骤 207中已建立了 Femto AP与服 务 SeGW之间的 IP安全隧道, 则无需执行本步骤。
303, Femto AP与服务 Femto GW建立可靠性传输会话端口;
304 , Femto AP通过上述会话端口向服务 Femto GW发送注册请求消息 , 该消息中包含: Femto AP的位置信息、 Femto AP标识和 Femto AP执行参数 等;
上述 Femto AP的位置信息可以是以下信息的一种或多种:
> Femto AP探测到的宏覆盖信息 (例如, 蜂窝信息) ; > Femto AP的地理位置信息 (例如, 全球定位信息) ; Femto AP的 Internet连接信息 (例如, Femto AP的 IP地址) 。
上述 Femto AP标识是全球统一的和永久的标识。
上述 Femto AP执行参数可以是 Femto AP选择的小区信息等。
305a, 接收到 Femto AP发送的注册请求消息后, Femto GW根据该消息 中携带的信息对 Femto AP执行接入控制 (例如, 根据注册请求消息中的位 置信息判断是否允许 Femto AP在该位置运营 /注册) ; 如果接入控制的结果 为 Femto GW同意 Femto AP注册, 则向 Femto AP返回注册成功响应消息;
305b, 如果 Femto GW拒绝了 Femto AP的注册请求(例如, 由于当前网 络拥塞, Femto AP在黑名单中, Femto AP在未授权的位置发起注册等原因拒 绝该注册请求) , Femto GW向 Femto AP返回注册失败消息, 并在该消息中 携带失败原因。
图 4是现有技术中 UE通过合法的 Femto AP注册到合法的核心网的方法 (即 UE接入到核心网的方法) 流程图, 具体包括如下步骤:
401 , UE与 Femto AP建立无线资源连接以作为信令消息或者业务数据的 承载;
402, UE通过向 Femto AP发送初始化非接入层消息(筒称为非接入层消 息) 触发注册过程; 上述非接入层消息可以是附着消息、 位置更新消息、 业 务请求消息等;
403 ,接收到 UE发送的非接入层消息后, Femto AP发现没有对应用户的 上下文标识信息 (即发现用户尚未注册 ) , 因此向服务 Femto GW发送注册 请求消息, 以便将用户信息注册到服务 Femto GW中;
上述注册请求消息中包含: 注册类型、 UE的标识 (例如: UE的国际移 动用户识别码 (IMSI ) ) 以及 Femto AP标识等信息。
404, 月良务 Femto GW对接入该 Femto AP的用户进行能力方面的检验, 如果允许用户使用 Femto AP提供的资源, 那么就接受注册, 建立用户上下文 并在向 Femto AP回复的注册响应消息中携带用户上下文标识信息;
405 , Femto AP向服务 Femto GW转发非接入层消息; 406 , 服务 Femto GW对 Femto AP转发的非接入层消息不做任何处理, 直接透传到服务核心网;
407, 服务核心网根据接收到的非接入层消息对用户进行安全认证;
408, 如果安全认证通过, 核心网侧对用户发送的非接入层消息进行相应 的操作, 并向 UE回复非接入层响应消息, 将核心网侧的信息带给 UE; 上述 响应消息在 UE和 CN之间透传 , Femto AP和服务 Femto GW不对该消息进 行处理。
以上介绍了现有的家庭基站系统以及基于该系统的 Femto AP初始化、 Femto AP注册以及 UE的注册流程。
现有的家庭基站有一个缺陷, 即一个家庭基站只能接入到一个核心网, 这就意味着一个家庭基站的用户通常只能是一个运营商网络的用户, 对于其 他运营商网络的用户, 需要与该运营商签署漫游协议才能接入。
但是, 同一覆盖下的两个运营商之间一般不存在漫游协议, 这将给家庭 基站的拥有者带来不便。 例如: 在中国有三个移动运营商, 且三个运营商都 有他们自己的 IP回程网络, 未来都将演进到 LTE的网络,如果三个运营商都 部署家庭基站系统; 对于一个家庭基站拥有者来说, 使用该家庭基站接入到 移动运营商网络的用户包括家庭基站拥有者的家人和朋友, 还可能包括临时 的拜访者, 他们很可能与家庭基站拥有者属于不同的运营商, 因此无法通过 该家庭基站接入移动运营商网络。 此外, 对于企业级的家庭基站用户, 为了 使不同运营商的用户接入, 企业需要采购多个不同运营商的家庭基站, 这将 导致资源和空间的浪费。

本发明的较佳实施方式
本发明的核心思想是:
在初始化过程中, 家庭基站接入点选择与该家庭基站接入点有权限接入 的各核心网都相连的家庭基站网关作为服务家庭基站网关; 并在接收到用户 设备发送的非接入层消息后, 将非接入层消息转发给服务家庭基站网关; 服 务家庭基站网关根据用户设备的网絡接入标识 (例如, 移动网络接入标识) 将非接入层消息转发给该标识对应的核心网; 或
在初始化过程中, 家庭基站接入点选择与该家庭基站接入点有权限接入 的各核心网分别相连的各家庭基站网关作为服务家庭基站网关; 并在接收到 用户设备发送的非接入层消息后, 根据用户设备的移动网络接入标识选择与 该标识所对应的核心网相连的目标服务家庭基站网关, 将非接入层消息转发 给目标服务家庭基站网关; 目标服务家庭基站网关将非接入层消息转发给与 其相连的核心网; 或
在初始化过程中,家庭基站接入点从服务 FMS获取该家庭基站接入点有 权限接入的各核心网的地址; 并在接收到用户设备发送的非接入层消息后, 根据用户设备的移动网络接入标识选择该标识所对应的核心网的地址, 根据 所述地址将非接入层消息转发给对应的核心网。
下面将结合附图和实施例对本发明进行详细描述。
第一实施例
图 5是本发明第一实施例的家庭基站系统结构示意图。 如图 5所示, 该 系统包含: Femto AP, 服务 SeGW, 服务 Femto AAA, 服务 FMS, 服务 CN1 和服务 CN2, 与服务 CN1和服务 CN2都相连的服务 Femto GW, 以及不同运 营商的用户终端 (例如, 服务 CN1的用户终端 UE1和服务 CN2的用户终端 UE2 ) ; 此外, 当服务地与初始地不同时, 该系统还包含初始 SeGW、 初始 Femto AAA和初始 FMS。
图 5所示的家庭基站系统所实现的功能与现有的家庭基站系统的主要不 同之处在于: 不同的运营商网络的用户终端能通过 Femto AP和 Femto GW接 入到对应的服务核心网 (筒称为核心网) 。
为了实现上述功能, Femto AP的拥有者可以根据需要向多个运营商申请 接入权限, 并在本地保存共享信息; 所述共享信息为 Femto AP有权限接入的 核心网的移动网络接入标识和接入权限信息,以及初始 FMS的地址。在 Femto AP的初始化过程中, Femto AP根据共享信息选择与其有权限接入的各核心 网都相连的 Femto GW作为服务 Femto GW, 并在 UE的注册过程中将 UE发 送的非接入层消息发送给该服务 Femto GW。
图 5中的服务 Femto GW与现有技术中的服务 Femto GW的不同之处在 于: 服务 Femto GW与多个核心网相连, 根据 UE的移动网络接入标识将 UE 的非接入层消息发送给对应的核心网, 完成 UE的注册。 此外, 图 5中的服务 Femto GW还可以在 Femto AP的注册过程中根据 Femto AP的共享信息生成 Femto AP的接入能力信息, 并将接入能力信息发 送给 Femto AP用于进行接入控制。
图 5中的 FMS (包括初始 FMS和服务 FMS ) 可以是共享的也可以是分 离的, 即 FMS (包括初始 FMS和服务 FMS ) 可以被多个核心网所共享, 也 可以各核心网分别对应的 FMS。
根据 FMS (包括初始 FMS和服务 FMS )的不同设置方式(共享或分离), Femto AP可以采用不同的方式选择服务 Femto GW, 并从服务 FMS获取配置 参数, 具体方式将在下文中详述。
图 5中的初始 SeGW、 服务 SeGW、 初始 Femto AAA和服务 Femto AAA 与现有技术中的相应网元的功能相同, 此处不再赘述。

606, Femto AP确认初始 FMS发送的信息, 根据该信息选择服务 FMS、 服务 SeGW和服务 Femto GW后, 向初始 FMS回送 TR069设置参数响应消 息;
607,如果服务 SeGW与初始 SeGW不同,则释放 Femto AP与初始 SeGW 之间的 IP安全隧道;
如果服务 SeGW就是初始 SeGW, 就不需要在 Femto AP与 SeGW之间 重建 IP安全隧道, 当然也就不需要释放 Femto AP与初始 SeGW之间的 IP安 全隧道。
608, 如果服务 SeGW与初始 SeGW不同, Femto AP建立与服务 SeGW 之间的 IP安全隧道;
在与服务 SeGW建立 IP安全隧道时, 需要服务 Femto AAA对 Femto AP 进行认证, 具体流程可参考相关文档。
609, Femto AP通过建立的 IP安全隧道向服务 FMS发送 TR069信息请 求消息, 该消息中携带 Femto AP的标识、 告警标识、 位置信息、 初始化标识 和 Femto AP的共享信息等参数;
610,服务 FMS对 Femto AP的接入权限进行认证,认证成功后,向 Femto AP返回 TR069信息请求响应消息;
611 , 服务 FMS根据 Femto AP的共享信息选择相应的服务 Femto GW, 并生成 Femto AP的配置参数;
其中,服务 FMS选择的服务 Femto GW与共享信息中标识的各核心网相 连。
612, 服务 FMS向 Femto AP发送 TR069设置参数请求消息 , 该消息中 携带: 与服务 Femto GW相关的服务 SeGW列表、 Femto AP的配置参数和鉴 权参数;
此外 , 如果步骤 605的 TR069设置参数请求消息中没有携带服务 Femto
GW列表, 则本步骤的 TR069设置参数请求消息中还需携带服务 Femto GW 列表。
613 , Femto AP确认服务 FMS发送的信息, 根据该信息选择服务 SeGW 和服务 Femto GW后, 向服务 FMS回送 TR069设置参数响应消息;
614,如果步骤 613中选择的服务 SeGW与步骤 606中选择的服务 SeGW 不同, 则 Femto AP释放步骤 608中建立的 IP安全隧道。
需要注意的是, 如果初始 FMS和服务 FMS相同 , 则步骤 601 ~ 607可省 略。
图 7是在图 5所示的系统中 Femto AP进行初始化的第二种方法流程图, 其中, 各运营商分别拥有各自的服务 FMS (即各服务 CN分别对应一个服务 FMS ) ; 如图 7所示, 该方法包括如下步骤:
701 , Femto AP上电后, 与初始 SeGW建立 IP安全隧道;
702, Femto AP通过建立的 IP安全隧道、 根据共享信息从初始 FMS1获 取对应的服务 FMS列表、服务 SeGW列表和服务 Femto GW列表, 并从服务 FMS列表中选择服务 FMS1 , 具体的过程与步骤 202 ~ 205相同;
