Description

家用基站网关转发消息至家用基站的方法及系统
技术领域 本发明涉及移动通信领域， 具体涉及家用基站网关向家用基站转发消息 的方法和系统。
背景技术 家用基站是一种小型、低功率的基站，部署在家庭及办公室等室内场所， 主要作用是为了给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， 同时弥补已有分布式蜂窝无线通信系统覆盖的不足。 家用基站的优点 是实惠、 便捷、 低功率输出、 即插即用等。 家用基站可以直接连接到核心网络， 如图 1所示， 也可以通过家用基站 网关这个逻辑网元接入到核心网络， 如图 2所示， 其中， 家用基站网关主要 功能为： 验证家用基站的安全性， 处理家用基站的注册， 对家用基站进行运 行维护管理， 根据运营商要求配置和控制家用基站， 负责交换核心网和家用 基站的数据。 接入网关可以是 S-GW (服务网关， Serving Gateway ) 、 P-GW (分组数据网网关， Packet Data Network Gateway ) 、 SGSN (服务 GPRS支 持节点， Serving GPRS Support Node )、 GGSN(网关 GPRS支持节点， Gateway GPRS Support Node )。鉴权授权服务器负责存储用户数据信息的核心数据库， 存放着用户的认证信息、 业务信息等等。 家用基站和家用基站网关之间的接 口可以釆用 S1AP ( SI Application Protocol, SI应用协议）协议实现。 除了支持移动核心网络的接入以外， 家用基站还可支持本地 IP访问功 能， 可实现终端对家用网络其他 IP设备或者互联网络的本地接入。 如图 1 和图 2所示，本地网关的增设可提供对本地 IP访问技术的有力支持，本地 IP 访问的实现可以釆用基于多 PDN (分组数据网， Packet Data Network )连接 方式（即本地 IP访问连接与非本地 IP访问连接可使用不同的 PDN连接来实 现 ) ,也可通过建立一个连接来同时实现核心网访问以及本地 IP的访问功能 , 本地网关可以与无线侧网元合设、 也可以与无线侧网元分设。 本地网关作为 本地接入到外部网络（例如 Internet )的网关， 提供地址分配、 计费、 分组包 过滤、 策略控制、 数据分流功能、 NAS ( Non- Access-Stratum, 非接入层） /S 1 -AP/RANAP ( Radios Access Network Application Part , 无线接入网应用部 分） /GTP ( General Tunneling Protocol, 通用隧道协议） /PMIP ( Proxy Mobile IP ,代理移动 IP协议）/MIP( Mobile IP ,移动 IP协议 )消息解析、 NAT( Network Address Translation, 网络地址转换） 、 本地 IP访问策略路由和执行等功能。 该网关可与家用基站进行合设。 以 LTE ( Long Term Evolution, 长期演进） 移动通信网络架构为例，图 3显示了家用基站系统本地 IP访问的示意数据流。 当存在家用基站网关的情况下，对于本地 IP连接，移动性管理实体向本 地接入发送的信令需要途径家用基站网关。 然而， 由于家用基站网关可以连 接多个家用基站， 仅仅根据目前的信令体， 家用基站网关无法将移动性管理 实体发送的消息转至正确的家用基站， 即用户本地 IP访问所在的家用基站， 故导致家用基站网关无法识别家用基站， 使得本地 IP访问功能无法正常运 作。
发明内容 本发明要解决的技术问题是提供一种家用基站网关转发消息至家用基站 的方法及系统， 实现本地 IP访问。 为了解决上述技术问题， 本发明提供一种家用基站网关转发消息至家用 基站的方法， 包括： 移动性管理实体在本地 IP连接建立时，向家用基站网关发送的消息中携 带用户标识信息和 /或家用基站标识信息； 家用基站网关根据收到的所述消息中携带的用户标识信息获取该用户标 识信息所对应的家用基站信息， 将所述消息发送给对应的家用基站， 或者根 据收到的所述消息中携带的所述家用基站标识信息将所述消息发送给对应的 家用基站。 上述方法还可具有以下特点： 所述移动性管理实体在本地 IP 连接建立时向家用基站网关发送的消息 为默认承载建立请求。 上述方法还可具有以下特点： 移动性管理实体在以下的一种或多种消息中携带用户标识信息和 /或家 用基站标识信息：在本地 IP连接建立过程中除默认承载建立请求外的其他由 移动性管理实体发向家用基站的消息， 专有承载建立过程、 专有承载连接过 程、 专有承载释放过程、 位置更新过程、 路由更新过程或跟踪区更新过程中 由移动性管理实体发向家用基站的消息。 上述方法还可具有以下特点： 所述家用基站网关根据收到的消息中携带的用户标识信息获取该用户标 识信息所对应的家用基站信息的步骤中， 所述家用基站网关根据所述用户标 识信息以及事先保存的用户标识信息和家用基站标识信息的对应关系获取对 应的家用基站信息。 上述方法还可具有以下特点： 所述家用基站网关通过以下方式之一事先保存用户标识信息和家用基站 标识信息的对应关系： 在通用陆地无线接入网 UTRAN系统中， 家用基站向家用基站网关发送 的注册请求消息中携带用户标识和家用基站标识， 家用基站网关收到所述消 息后， 保存该用户标识和家用基站标识的对应关系； 在通用陆地无线接入网 UTRAN系统中， 家用基站向家用基站网关发送 的初始用户消息中携带用户标识， 家用基站网关收到所述消息后， 保存该用 户标识和发送该消息的家用基站的家用基站标识信息的对应关系； 在演进的通用陆地无线接入网 EUTRAN 系统中， 家用基站向家用基站 网关发送的初始用户消息中携带有用户标识，家用基站网关收到所述消息后， 保存该用户标识和发送该消息的家用基站的家用基站标识信息的对应关系。 上述方法还可具有以下特点： 所述家用基站标识信息为以下信息的一种或几种： 家用基站标识、 小区 标识、 家用基站地址、 本地网关地址。 上述方法还可具有以下特点： 当所述家用基站标识信息为家用基站标识和 /或小区标识时，所述家用基 站网关根据所述家用基站标识信息将所述消息发送给对应的家用基站的步骤 中， 家用基站网关根据所述家用基站标识信息获取家用基站信息， 将所述消 息发送给对应的家用基站。 上述方法还可具有以下特点： 所述家用基站信息包括以下信息中的一种或几种： 隧道标识、 家用基站 地址、 本地网关地址。 上述方法还可具有以下特点： 所述移动性管理实体为以下网元之一： 移动管理单元 MME、 移动交换 中心 MSC、 服务 GPRS支持节点 SGSN; 本地 IP连接是以下一种或多种连接： 本地 IP访问用户本地网络、 本地 IP访问公司本地网络、 本地 IP访问互联网、 互联网业务的分流操作、 特定 IP数据分流。 为了解决上述技术问题， 本发明提供一种家用基站网关， 所述家用基站 网关设置成： 根据自移动性管理实体收到的消息中携带的用户标识信息获取 该用户标识信息所对应的家用基站信息，将所述消息发送给对应的家用基站， 或者根据收到的所述消息中携带的家用基站标识信息将所述消息发送给对应 的家用基站。 上述家用基站网关还可具有以下特点： 所述家用基站网关还设置成： 根据所述用户标识信息以及事先保存的用 户标识信息和家用基站标识信息的对应关系获取对应的家用基站信息。 上述家用基站网关还可具有以下特点： 所述家用基站网关还设置成： 通过以下方式之一事先保存用户标识信息 和家用基站标识信息的对应关系： 在通用陆地无线接入网 UTRAN系统中， 家用基站向家用基站网关发送 的注册请求消息中携带用户标识和家用基站标识， 家用基站网关收到所述消 息后， 保存该用户标识和家用基站标识的对应关系； 在通用陆地无线接入网 UTRAN系统中， 家用基站向家用基站网关发送 的初始用户消息中携带用户标识， 家用基站网关收到所述消息后， 保存该用 户标识和发送该消息的家用基站的家用基站标识信息的对应关系； 在演进的通用陆地无线接入网 EUTRAN 系统中， 家用基站向家用基站 网关发送的初始用户消息中携带有用户标识，家用基站网关收到所述消息后， 保存该用户标识和发送该消息的家用基站的家用基站标识信息的对应关系。 为了解决上述技术问题， 本发明提供一种家用基站网关转发消息至家用 基站的系统， 包括： 移动性管理实体、 上述家用基站网关和家用基站； 其中， 所述移动性管理实体设置成： 在本地 IP连接建立时， 向家用基站网关发 送的消息中携带用户标识信息和 /或家用基站标识信息。 上述系统还可具有以下特点： 所述移动性管理实体还设置成： 在以下的一种或多种消息中携带用户标 识信息和 /或家用基站标识信息： 在本地 IP连接建立过程， 专有承载建立过 程、 专有承载连接过程、 专有承载释放过程、 位置更新过程、 路由更新过程 或跟踪区更新过程中由移动性管理实体发向家用基站的消息。 为了解决上述技术问题， 本发明提供一种家用基站网关， 包括相连的接 收模块和发送模块， 所述接收模块设置成： 接收移动性管理实体发送的消息； 所述发送模块设置成： 根据接收模块收到的所述消息中携带的用户标识 信息获取该用户标识信息所对应的家用基站信息， 将所述消息发送给对应的 家用基站， 或者根据接收模块收到的所述消息中携带的所述家用基站标识信 息将所述消息发送给对应的家用基站。

附图概述 附图说明用来提供对本发明的进一步理解， 并且构成说明书的一部分， 与本发明的实施例一起用于解释本发明， 并不构成对本发明的限制。 在附图 中：
图 1为现有技术中家用基站网络连接示意图一； 图 2为现有技术中家用基站网络连接示意图二； 图 3为现有技术中家用基站系统本地 IP接入数据流示意图； 图 4为本发明实施例的用户初始接入时建立本地 IP连接的流程图； 图 5是本发明实施例的用户初始接入后进行本地 IP连接建立过程流程 图。
本发明的较佳实施方式 本发明的发明构思是： 移动性管理实体在本地 IP连接建立时， 向家用基 站网关发送的消息中携带用户标识信息和 /或家用基站标识信息； 家用基站网 关根据收到的所述消息中携带的用户标识信息获取该用户标识信息所对应的 家用基站信息， 将所述消息发送给对应的家用基站， 或者根据收到的所述消 息中携带的所述家用基站标识信息将所述消息发送给对应的家用基站。 上述移动性管理实体在本地 IP 连接建立时向家用基站网关发送的消息 为默认承载建立请求。此外， 除了在本地 IP连接建立时发送的默认承载建立 请求中携带用户标识信息或者家用基站标识信息， 移动性管理实体在其他消 息中也可通过携带用户标识信息或者家用基站标识信息的方式， 使家用基站 网关转发消息， 例如，在本地 IP连接建立过程中除默认承载建立请求外的其 他由移动性管理实体发向家用基站的消息， 或者是专有承载建立、 连接或承 载释放、 位置更新、 路由更新或跟踪区更新等过程中由移动性管理实体发向 家用基站的消息。
入网） 系统中， 家用基站向家用基站网关发送的注册请求消息中携带用户标 识和家用基站标识， 家用基站网关收到所述消息后， 保存该用户标识和家用 基站标识的对应关系； 或者家用基站向家用基站网关发送的初始用户消息中 携带用户标识， 家用基站网关收到所述消息后， 保存该用户标识和发送该消 息的家用基站的家用基站标识信息的对应关系。 在 EUTRAN ( Evolved Universal Terrestrial Radio Access Network, 演进 的通用陆地无线接入网） 系统中， 家用基站向家用基站网关发送的初始用户 消息中携带有用户标识， 家用基站网关收到所述消息后， 保存该用户标识和 发送该消息的家用基站的家用基站标识信息的对应关系。
下面结合附图和具体实施例对本发明所述技术方案作进一步的详细描 述， 以使本领域的技术人员可以更好的理解本发明并能予以实施， 但所举实 施例不作为对本发明的限定。 图 4是本发明在图 2家用基站系统的基础上， 用户初始接入时进行本地 IP连接建立过程流程图。 本实施例具体步骤描述如下： 步骤 401 , 用户在进行通信前需要建立 RRC ( Radio Resource Control, 无线资源控制 )连接作为信令消息或者业务数据的承载， RRC连接请求消息 携带用户标识， 家用基站保存该用户标识； 步骤 402, 用户通过初始化 NAS消息触发注册过程； 步骤 403 , 家用基站发现没有该用户的上下文标识信息， 向家用基站网 关发送注册请求消息， 将用户信息注册到家用基站网关上， 消息内容包括注 册的类型、 用户标识信息以及家用基站标识信息等， 家用基站网关可以在收 到该包含用户标识信息以及家用基站标识信息的注册请求消息后， 保存用户 标识信息和家用基站标识信息的对应关系； 用户标识例如可以是 IMSI ( International Mobile Subscriber Identification Number, 国际移动客户识别码 )或临时用户标识。 步骤 404, 家用基站向家用基站网关发送连接（Connect )建立消息， 也 称初始的用户消息； 在另一实施例中， 家用基站可以在本步骤的初始用户消息中携带用户标 识信息， 这样， 家用基站网关也可以在此时保存用户标识信息和发送该初始 用户消息的家用基站的家用基站标识信息的对应关系。 步骤 405 , 家用基站网关发起连接建立， 将初始的用户消息发给移动性 管理实体， 并在该初始用户消息中携带 NAS消息， 转发至移动性管理实体， 该 NAS消息中携带有用户标识， 还可以携带有家用基站标识信息； 步骤 406, 移动性管理实体回复连接建立响应； 步骤 407, 移动性管理实体开启鉴权以及安全流程， 对用户进行验证； 步骤 408, 移动性管理实体根据特殊的 APN ( Access Point Name, 接入 点名称）或本地访问标识（这些标识可以在步骤 405消息中携带）发现需建 立本地 IP连接后， 向家用基站网关发送默认承载建立请求，携带用户标识信 息 (包括真实的用户标识和临时用户标识）或 /和家用基站标识信息； 如果移动性管理实体此时还未获得初始上下文建立响应， 但在步骤 405 中得到了临时用户标识， 则在本步骤的默认承载建立请求中携带临时用户标 识。 步骤 409, 接收到移动性管理实体发送的消息， 家用基站网关解析该消 息，如果该消息存在家用基站标识，则向该家用基站发送默认承载建立请求； 如果该消息存在用户标识， 则根据该真实的用户标识或者临时用户标识获取 对应的家用基站信息， 然后将默认承载建立请求消息发送给该家用基站； 步骤 410 , 家用基站 /本地网关经家用基站网关回复移动性管理实体默认 载建立响应； 步骤 411 , 移动性管理实体经家用基站网关向家用基站 /本地网关发起初 始上下文建立请求； 步骤 412, 终端与家用基站 /本地网关之间执行 RRC连接配置过程； 步骤 413 , 家用基站 /本地网关经家用基站网关回复移动性管理实体初始 上下文建立响应； 在执行该步初始上下文建立响应， 且移动性管理实体重新分配临时标识 之后， 移动性管理实体可以释放步骤 405中得到了临时用户标识。 步骤 414, 继续执行用户接入相关的其他流程。
为了简化描述， 以上实施例仅以 UTRAN系统的应用场景为例来说明家 用基站网关对家用基站的识别方式。 在 E-UTRAN的情况下， 由于不存在上 述家用基站向家用基站网关进行用户注册的步骤（即步骤 403 ) , 因此家用 基站可以在向家用基站网关发送的初始用户消息中携带用户标识 （即步骤 404 ) , 以便家用基站网关可以保存用户标识和家用基站标识的对应关系。 此 夕卜， 在 E-UTRAN系统中， 家用基站网关识别家用基站的方式与上述实施例 极为相似， 不会对阐述本发明造成影响， 故在此不再重复描述。
图 5是本发明在图 2家用基站系统的基础上， 用户初始接入后进行本地
IP连接建立过程流程图。 本实施例具体步骤描述如下： 步骤 501 , 终端已经附着到网络， 具有核心网 PDN (分组数据网， Packet Data Network )连接； 步骤 502, 终端经家用基站和家用基站网关向移动性管理实体发起 PDN 连接请求； 步骤 503 , 移动性管理实体根据特殊的 APN ( Access Point Name, 接入 点名称）或本地访问标识（这些标识可以在步骤 502消息中携带）发现需建 立本地 IP连接并且该本地 IP连接为首次建立后， 向家用基站网关发送默认 承载建立请求， 携带用户标识信息 （包括真实的用户标识和临时用户标识） 和 /或家用基站标识信息； 如果已经获得初始上下文建立响应， 则移动性管理实体在默认承载建立 请求中携带当前的临时用户标识。 该用户标识是移动性管理实体中保存的最 新临时用户标识。 由于移动性管理实体可以更改临时用户标识， 通过初始上下文建立请求 带给家用基站（图 4中的 411步） ， 因此， 如果是初始上下文建立之前发送 默认承载建立请求， 则需要带移动性管理实体修改前的临时用户标识， 如果 是初始上下文建立之后发送默认承载建立请求， 则带移动性管理实体修改后 的临时用户标识 （如果修改的话） 。 步骤 504, 接收到移动性管理实体发送的消息， 家用基站网关解析该消 息，如果该消息存在家用基站标识，则向该家用基站发送默认承载建立请求； 如果该消息存在用户标识， 则根据该真实的用户标识或者临时用户标识获取 对应的家用基站信息， 然后将默认承载建立请求消息发送给该家用基站； 步骤 505, 家用基站 /本地网关经家用基站网关回复移动性管理实体默认 载建立响应； 步骤 506, 移动性管理实体经家用基站网关向家用基站 /本地网关发起承 载建立请求； 步骤 507, 终端与家用基站 /本地网关之间执行 RRC连接配置过程； 步骤 508, 家用基站 /本地网关经家用基站网关回复移动性管理实体承载 建立响应； 步骤 509 , 继续执行用户接入相关的其他流程。
