Description

本地连 4妻信息的发送方法^ ^置 技术领域 本发明涉及通信领域, 具体而言, 涉及一种本地连接信息的发送方法及 装置。 背景技术 为了保持第三代移动通信系统在通信领域的竟争力, 为用户提供速率更 快、 时延更低、 更加个性化的移动通信服务, 同时, 降低运营商的运营成本, 第三代合作伙伴计划 (3rd Generation Partnership Project, 简称为 3GPP ) 标 准工作组正致力于演进分组系统( Evolved Packet System, 简称为 EPS )的研 究。 图 1是根据相关技术的演进分组域系统的结构示意图, 如图 1所示, 只 包含和本发明相关网元。 整个 EPS系统分为无线接入网和核心网两部分。 在 核心网中, 包含了归属用户服务器 ( Home Subscriber Server, 简称为 HSS )、 移动性管理实体 ( Mobility Management Entity , 简称为 ΜΜΕ ), 月艮务通用分 组无线业务支持节点( Serving General Packet Radio Service Support Node, 简 称为 SGSN )、 策略计费规则功能 ( Policy and Charging Rule Function, 简称 为 PCRF ),月艮务网关( Serving Gateway, 简称为 S-GW ),分组数据网关( PDN Gateway, 简称为 P-GW ) 和分组数据网络 ( Packet Data Network, 简称为 PDN )。 下面详细各部分功能: 归属用户服务器, 是用户签约数据的永久存放地点, 位于用户签约的归 属网。 移动性管理实体, 是用户签约数据在当前网络的存放地点, 负责终端到 网络的非接入层信令管理、 终端的安全验证功能、 终端的移动性管理、 用户 空闲模式下的跟踪和寻呼管理功能和承载管理。 服务 GPRS支持节点, 是 GERAN和 UTRAN用户接入核心网络的业务 支持点, 功能上与移动性管理实体类似, 负责用户的位置更新、 寻呼管理和 承载管理等功能。 月艮务网关, 是核心网到无线系统的网关, 负责终端到核心网的用户面 7 载、 终端空闲模式下的数据緩存、 网络侧发起业务请求的功能、 合法监听和 分组数据路由和转发功能; 服务网关负责统计用户终端使用无线网的情况, 并产生终端使用无线网的话单, 传送给计费网关。 分组数据网关, 是演进系统和该系统外部分组数据网络的网关, 它连接 到因特网和分组数据网络上, 负责终端的互联网协议 ( Internet Protocol , 简 称为 IP ) 地址分配、 计费功能、 分组包过滤、 策略控制等功能。 分组数据网络, 是运营商的 IP业务网络, 该网络通过运营商的核心网为 用户提供 IP服务。 策略计费规则功能实体, 是演进系统中负责提供计费控制、 在线信用控 制、 门限控制、 月艮务质量( Quality of Service, 简称为 QoS )策略方面规则的 服务器。 无线接入网, 是由演进基站( E-UTRAN NodeB , 简称 eNB )和 3G无线 网络控制器 (Radio Network Control, 简称 RNC ) 组成, 它主要负责无线信 号的收发, 通过空中接口和终端联系, 管理空中接口的无线资源、 资源调度、 接入控制。 上述月艮务 GPRS支持节点是升级过的 SGSN, 能够支持与月艮务网关之间 的 S4接口, 并与移动性管理单元之间釆用 GTPv2协议进行互通。 而对于支 持 3G核心网的 SGSN来说 PS域网络架构与图 1有所不同。 此时 SGSN与 MME釆用 Gn接口相连, 互通釆用 GTPvl协议。 SGSN不能与服务网关相 连, 通过 Gn接口连接到网关 GPRS支持节点( Gateway GPRS Support Node, 简称为 GGSN ) 直接进行分组数据网络访问。 家庭基站 (Home NodeB , 简称为 HNB ) 或者演进的家庭基站 (Home eNodeN, 简称为 HeNB )是一类小型、 低功率的基站, 作为某些用户的专属 资源, 部署在家庭、 团体、 公司或者学校等私人场所使用, 主要是为了给用 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。 家庭基站的优点是实惠、 便捷、 低功 率输出、 即插即用、 宽带接入、 使用单模终端等。 家庭基站可以应用在第三代 ( 3 Generation, 简称为 3G ) 或者长期演进 ( Long Term Evolution, 简称为 LTE ) 移动通信网络中。 为了便于对家庭基 站进行管理, 在网络中引入了一个新网元, 即家庭基站网关。 家庭基站网关 主要执行的功能为: 验证家庭基站的安全性, 对家庭基站的运行进行维护管 理, 根据运营商要求配置和控制家庭基站, 负责交换核心网和家庭基站的数 据信息。 图 2是根据相关技术的 3G家庭基站网络架构示意图, 3G家庭基站通过 新定义的 Iuh接口连接至家庭基站网关, 家庭基站网关提供到核心网分组域 和电路域的 iups和 luCs接口。 对于 3G网络来说家庭基站网关必选部署用 来屏蔽引入家庭基站后对终端和网络侧的影响。 图 3是根据相关技术的 LTE家庭基站网络架构示意图一, 图 4是根据相 关技术的 LTE家庭基站网络架构示意图二,对于 LTE网络来说家庭基站网关 可选部署, 因此 LTE家庭基站和核心网连接有两种方式, 一种是演进家庭基 站和核心网网元直接相连 (如图 3 所示), 另一种是演进家庭基站通过演进 家庭基站网关和核心网网元相连 (如图 4所示;)。 图 5是根据相关技术的 LTE家庭基站网络架构示意图三, 如图 5所示, 基于图 4的演进家庭基站网关的场景, 演进家庭基站网关可以不集成用户面 功能, 演进家庭基站和核心网用户面网关间直接建立用户面, 这样可以使用 户面扁平化, 数据传输时延减小。 家庭基站除了支持通过移动核心网络的接入之外,还可以支持本地 IP接 入功能, 在家庭基站具备本地 IP接入能力并且用户签约允许本地 IP访问的 条件下, 可以实现用户对家庭网络其他 IP设备或者互联网络的本地接入。 通 过本地接入功能, 可以实现 Internet数据业务的分流, 降低核心网负荷, 并 且对于家庭网络设备的访问可以不通过核心网来进行转发, 数据传输便捷高 效。 本地 IP接入功能在宏蜂窝上也可以使用, 主要用途和家庭基站类似, 更 多的是应用在本地 IP接入 Internet这种场景, 目的是降低核心网负荷。 图 6是根据相关技术的实现本地接入的网络架构示意图一, 图 7是根据 相关技术的实现本地接入的网络架构示意图二, 如图 6和图 7所示, 给出了 实现上述本地接入功能的架构, 主要差别体现在是否存在家用基站网关。 其 中, 本地接入网关作为本地接入到外部网络(例如 internet ) 的网络, 提供地 址分配、计费、分组包过滤、策略控制、数据分流功能、 NAS/RANAP ( Radios Access Network Application Part, 无线接入网应用部分) 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。 该网元作为一个逻辑单元模块在实际部署的时候可以将其和现有 的家用基站或者家用基站网关联合部署, 也可以单独部署。 对于宏蜂窝实现 本地接入架构, 无线接入网关建议将其和基站或者无线网络控制节点( RNC ) 联合部署, 可以通过图 7的架构实现。 在这种架构下移动管理单元和本地接入网关之间并没有直接的接口, 而 为了建立本地连接本地接入网关需要获得一些必要的信息。 国际移动用户 i只别码 ( International Mobile Subscriber Identity, 简称为 IMSI )作为用户设备(User Equipment, 简称为 UE ) 的唯一标识, 能够全球 唯一的标识一个 UE。 该标识由运营商分配, 由于该标识是签约数据, 因此 一般来说只能在归属运营商内部或者与归属运营商签订了漫游协议的其他运 营商使用。 而本地接入网络由于处于无线侧或者在运营商无法确认安全的位 置, 因此 IMSI 不适合保存在本地接入网关, 而为了能够标识 UE, 可以将 UE的临时标识保存在本地接入网关。
UE可以通过建立不同的接入点名称( Access Point Name , 简称为 ΑΡΝ ) 来访问不同的网络业务, 这些网络业务可以通过一个网关节点或者多个网关 节点。 同样的, 如果 UE通过本地接入网关连接到外部网络或者运营商业务, 为了区分不同的业务, 也可以建立多个 ΑΡΝ 连接。 因此本地接入网关需要 通过不同的 ΑΡΝ来标识不同的网元业务。 发明内容 4十对本地接入网关无法通过不同的 ΑΡΝ 和临时用户标识来标识不同的 网元业务的问题而提出本发明, 为此, 本发明的主要目的在于提供一种本地 连接信息的发送方法及装置, 以解决上述问题。 为了实现上述目的, 根据本发明的一个方面, 提供了一种本地连接信息 的发送方法。 该方法包括: 移动性管理单元确定为终端建立本地连接;
