切换过程中本地访问连接的处理方法及装置 技术领域 本发明涉及通信领域, 具体而言, 涉及一种切换过程中本地访问连接的处理方法 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竞争力, 为用户提供速率更快、 时延 更低、 以及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 EPS) 的研究。 图 1示出了演进分组域系统的 结构示意图, 如图 1所示, 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 MME)、 服务 GPRS支持节点 (Serving GPRS Support Node, 简称为 SGSN)、策略计费规则功能(Policy and Charging Rule Function, 简称为 PCRF)、 服务网关 (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 PDN)。 下面 详细描述各部分功能: 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, 是全球移动通讯系统 (Global System for Mobile Communications, 简称为 GSM) 增强数据率 GSM演进 (Enhanced Data Rate for GSM Evolution, 简称为 EDGE) 无线接入网 (GSM EDGE Radio Access Network, 简称为 GERAN)和通用移动通信系统 (Universal Mobile Telecommunications System, 简称为 UMTS) 陆地无线接入网 (UMTS Terrestrial Radio Access Network, 简称为 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。 服务网关, 是核心网到无线系统的网关, 负责终端到核心网的用户面承载、 终端 空闲模式下的数据缓存、 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时产 生的话单, 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、 以及策略控制等功能。 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、 以及服务质量 (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 (Evolved NodeB, 简称为 e B) 和 3G无线网络控制 器 (Radio Network Controller, 简称为 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、 以及接入控制。 上述服务 GPRS支持节点是升级过的 SGSN,能够支持与服务网关之间的 S4接口, 并与移动性管理单元之间采用 GPRS隧道协议版本 2 (GPRS Tunneling Protocol version 2, 简称为 GTPv2) 进行互通。 而对于支持 3G核心网的 SGSN来说分组交换 (Packet Switching, 简称为 PS) 域网络架构与图 1有所不同。 此时 SGSN与 MME采用 Gn接 口相连, 互通采用 GPRS隧道协议版本 1 ( GPRS Tunneling Protocol version 1, 简称为 GTPvl )。 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 eNodeB, 简称为 He B)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 使用高速率服务所产生的费用, 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、 以及使用单模终 端等。 家庭基站可以直接连接到核心网络, 如图 2 (a) 所示, 也可以通过家庭基站网关 这个逻辑网元接入到核心网络, 如图 2 (b)所示, 其中, 家庭基站网关的主要功能为: 验证家庭基站的安全性, 处理家庭基站的注册, 对家庭基站进行运行维护管理, 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。 为了实现本地访问功能 (包括本地 IP访问 (Local IP Access, 简称为 LIPA) 或者 选择性 IP传输分流 (Selected IP Traffic Offload, 简称为 SIPTO)), 即终端对家用网络 其他 IP设备、企业网络中的 IP设备或者互联网络的本地接入,增设了本地网关(Local Gateway, 简称为 L-GW), 如图 3所示。 本地接入网关的增设可提供对本地访问技术 的有力支持, 本地网关可以和无线侧网元合设或者设置在无线侧网元附近 (即外置)。 本地网关包括本地 PGW (Local PGW, 简称为 L-PGW)、 本地 GGSN (Local GGSN, 简称为 L-GGSN)。 在移动通信网络架构中, 本地访问和传统核心网访问的数据流路径如图 3所示。 对于支持本地访问的用户, 可以同时建立传统的核心网访问数据路径和本地访问数据 路径。 对于本地访问的连接, 本地访问数据路径从终端至无线侧网元至本地接入网关 (如: L-PGW以及 L-GGSN), 数据传输不经过核心网。 为了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, 可以建立两条连接, 第一条本地访问数据路径直 接访问互联网 (互联网 IP连接, 也即 SIPTO连接)。 第二条本地访问数据路径直接访 问家用网络其他 IP设备 (家用网络 IP连接, 也即 LIPA连接)。 图 4为企业网络支持本地访问的网络架构图, 以 3G网络部署方式为例进行说明, LTE网络的部署方式类似, 只是具体采用的接口不同, 不再赘述。 一个企业网络可以 部署一个或者多个本地家庭基站网络, 本地家庭基站网络是由若干个家庭基站构成, 用以覆盖不同的区域。 本地家庭基站网络内的基站可以通过一个或者几个本地网关为 用户的本地访问提供 IP连接。一个企业本地网络内的家庭基站仅属于唯一的一个本地 家庭基站网络。 本地网关部署在家庭基站和家庭基站网关之间的接口上, 监听家庭基 站和家庭基站网关之间接口的消息为用户提供本地访问业务, 一个 L-GW仅属于一个 单独的本地家庭基站网络。 用户通过家庭基站以及本地网关接入分组数据网络享受本 业务, 数据分组网络可以为多个本地家庭基站网络内的用户提供服务。 由于企业网络 设备是通过互联网作为传输承载接入到核心网网络, 移动网络运营商认为此种接入是 非授信的, 所以企业网络的设备接入核心网需要通过移动网络运营商的安全网关
( Security Gateway, 简称为 SeGW) 设备, 也即需要建立家庭基站 (或者本地网关) 与安全网关之间的 IP安全 (IP security, 简称为 IPsec) 隧道保证核心网安全。 上述企业网络支持本地访问的架构可以支持用户在同一个本地家庭基站网络内本 地访问业务的连续性。 由于本地网关部署在基站和家庭基站网关之间的接口上, 并且 能监控所有本地家庭基站网络内家庭基站的注册消息, 因此本地网关能够发现连接状 态下的用户是否切换到本地家庭基站网络之外的目标基站, 通过目标基站标识的判定 可以初步决定本地访问移动性是否支持。 同理, 家庭基站网关可以根据家庭基站注册 时所记录的本地网关和下属家庭基站的对应关系发现用户切换的目标基站是否和源家 庭基站一样在同一个本地网关服务范围内, 从而也可以进行本地访问移动性的判定。 虽然此架构对移动性的判定具有实现上的优势, 但是现有技术对上述架构中本地网关 进行移动性支持范围的判定和 /或对本地访问接入的判定, 以及对本地访问连接的处理 的具体实现尚无法支持。 发明内容 本发明提供了一种切换过程中本地访问连接的处理方法及装置, 以解决上述问题 至少之一。 本发明的一个方面提供了一种切换过程中本地访问连接的处理方法, 包括: 预定 网元监测无线接入接口信令消息;

2)如果家庭基站网关仅进行本地访问移动性的判定(一个可能的原因是家庭基站 网关当前通过监测获取到目标基站信息且未获取到用户本地访问能力信息), 贝 U: 如果家庭基站网关判定用户在目标基站下无法支持本地访问移动性, 那么家庭基 站网关通知本地网关或者核心网移动性管理单元释放本地访问连接; 如果家庭基站网关判定用户在目标基站下可以支持本地访问移动性, 那么家庭基 站网关保持本地访问连接。 在(2)这种情况下, 一种完善本地访问接入控制判定的方式是家庭基站网关可以 将此本地访问移动性判定结果通知核心网移动性管理单元, 由核心网移动性管理单元 结合目标基站信息和本地访问签约信息进一步执行本地访问接入控制判定, 核心网移 动性管理单元根据判定结果对本地访问连接执行维持或者释放操作。 具体地, 如果判 定结果为用户在目标基站下支持本地访问移动性, 在家庭基站网关根据目标基站信息 进行本地访问移动性的判定之后, 家庭基站网关可以将本地访问移动性的判定结果通 知核心网移动性管理单元; 核心网移动性管理单元根据目标基站信息和本地访问签约 信息执行本地访问接入控制的判定; 核心网移动性管理单元在判定结果为用户在目标 基站下支持本地访问接入的情况下, 保持本地访问连接, 继续执行切换过程, 在判定 结果为用户在目标基站下不支持本地访问接入的情况下, 释放本地访问连接。 其中, 本地访问移动性的判定结果可以通过显示的指示信息指示, 也可以通过本地访问参数 (如本地访问承载信息) 的有无来指示。 在(2)这种情况下, 另外一种完善本地访问接入控制判定的方式是家庭基站网关 与核心网移动性管理单元交互完成本地访问接入控制判定。 如果判定结果为用户在目 标基站下支持本地访问移动性, 在预定网元根据目标基站信息进行本地访问移动性的 判定之后, 具体可采用如下两种方式: 家庭基站网关将目标基站信息发送至核心网移动性管理单元; 核心网移动性管理 单元根据目标基站信息和本地访问签约信息执行本地访问接入控制的判定, 并将判定 结果返回家庭基站网关; 家庭基站网关在判定结果为用户在目标基站下支持本地访问 接入的情况下, 保持本地访问连接, 继续执行切换过程, 在判定结果为用户在目标基 站下不支持本地访问接入的情况下, 释放本地访问连接; 或者, 家庭基站网关向核心网移动性管理单元获取用户本地访问能力信息, 根据目标基 站信息和获取的用户本地访问能力信息进行本地访问接入控制的判定, 在判定结果为 用户在目标基站下支持本地访问接入的情况下, 保持本地访问连接, 继续执行切换过 程, 在判定结果为用户在目标基站下不支持本地访问接入的情况下, 释放本地访问连 接。 在预定网元为本地网关的情况下, 由本地网关释放本地访问连接, 在预定网元为 家庭基站网关的情况下, 由家庭基站指示本地网关或核心网移动性管理单元释放本地 访问连接, 以下分别进行说明。 (一)预定网元为本地网关, 本地网关决定释放本地访问连接时, 中止切换过程, 发起本地访问连接释放。 具体地: 本地网关决定释放本地访问连接时, 中止切换过程, 发起本地访问连接释放, 在 收到核心网移动性管理单元返回的本地访问承载删除消息时删除源至目标容器 ( Source to Target Container) 中的本地访问承载信息然后继续执行切换过程 (向核心 网移动性管理单元发起切换请求), 具体处理过程见实施例 1和 2; 或者, 本地网关决定释放本地访问连接时, 指示源家庭基站终止切换过程并通知源家庭 基站在收到核心网移动性管理单元返回的携带本地访问承载释放信息的承载释放消息 时重新发起切换过程, 本地网关发起本地访问连接释放, 源家庭基站在收到核心网移 动性管理单元返回的携带本地访问承载释放信息的承载释放消息时, 重新发起切换过 程。 具体处理过程见实施例 1和 2。

或者, 家庭基站网关决定通知本地网关或者核心网移动性管理单元释放本地访问连接 时, 中止切换过程。 家庭基站网关指示本地网关或核心网移动性管理单元发起本地访 问连接释放, 并指示源家庭基站终止切换过程以及通知源家庭基站在收到核心网移动 性管理单元返回的携带本地访问承载释放信息的承载释放消息时重新发起切换过程; 源家庭基站在收到核心网移动性管理单元返回的携带本地访问承载释放信息的承载释 放消息时, 重新发起切换过程, 具体处理过程见实施例 3-6。 优选地,目标基站信息可以包括: 目标基站标识 /地址、目标基站闭合用户组(CSG) 标识等可以标识目标基站属性的信息。 用户本地访问能力信息可以包括: 用户本地访 问业务接入点名所绑定的闭合用户组标识信息、用户本地访问业务所支持的基站标识 / 地址集合信息等可以标识用户本地访问业务支持范围的信息。 所述用户本地访问业务 可以是当前已激活的业务也可以是用户所签约的所有本地访问业务。 以上的本地访问移动性的判定包括: 对用户在目标基站下是否移动出本地家庭基 站网络的判定。 支持本地访问移动性也即用户在目标基站下未移动出本地家庭基站网 络, 不支持本地访问移动性也即用户在目标基站下移动出本地家庭基站网络。 可选的 以上判定过程可结合用户本地访问能力信息进行本地家庭基站网络内用户可支持本地 访问业务的范围判定。 本地访问接入控制的判定包括: 用户在目标基站下是否支持已激活的本地访问业 务的判定。 支持本地访问接入也即用户在目标基站下支持已激活的本地访问业务。 不 支持本地访问接入也即用户在目标基站下不支持已激活的本地访问业务。 可选的, 以 上判定过程中, 本地网关可以根据用户本地访问能力信息获知或者通过与核心网移动 性管理实体进行信令交互后获知。 需要说明的是, 对于本地访问移动性和本地访问接入控制, 无论使用哪种称呼, 所指代的判定内容不会发生本质改变, 即即使判定名称发生变化, 本申请中的所有的 实施例是同样适用的。 随着技术的发展, 对于本地访问移动性或本地访问接入控制产 生了更合适的称呼, 使用该称呼来替换本地访问移动性或本地访问接入控制并不影响 本申请的所有实施方式的实施。 图 6是根据本发明实施例的切换过程中本地访问连接的处理装置的结构框图, 该 装置包含在预定网元中, 该装置包括: 获取模块 62, 设置为监测无线接入接口信令消 息获取目标基站信息和 /或本地访问接入能力信息; 判定模块 64, 耦合至获取模块 62, 设置为根据目标基站信息进行本地访问移动性的判定, 和 /或, 根据目标基站信息和用 户本地访问能力信息进行本地访问接入控制的判定;处理模块 66,耦合至判定模块 64, 设置为根据判定结果在切换过程中对本地访问连接进行处理; 其中, 预定网元为本地 网关或家庭基站网关。 通过以上的结构, 获取模块 62监测无线接入接口信令消息获取目标基站信息和 / 或本地访问接入能力信息, 判定模块 64 根据目标基站信息进行本地访问移动性的判 定,和 /或,根据目标基站信息和用户本地访问能力信息进行本地访问接入控制的判定, 处理模块 66根据判定结果对本地访问连接进行处理,解决了相关技术中对本地网关进 行移动性支持范围的判定和 /或对本地访问接入的判定, 以及对本地访问连接的处理的 具体实现尚无法支持的问题, 能够实现本地访问接入功能, 并且能够支持本地家庭基 站网络内移动性的要求, 该方案对现有核心网的升级改造影响较小, 易于实现。 以下描述的实施例 1-6, 综合了上述多个优选实施例的技术方案。 实施例 1 图 7是根据实施例 1的切换过程中本地访问连接的处理方法的流程图, 本实施例 以 3G网络的切换过程为例进行本地访问连接处理方法的说明, 具体如下: 步骤 701, 在用户进入连接状态时, SGSN通过 Iu接口消息 (RAB指派消息、 下 行传输消息或者切换请求消息) 将用户本地访问能力信息下发给无线侧网元, 由于 L-GW部署在家庭基站与家庭基站网关之间的 Iuh接口上, 因此 L-GW可以获知这一 信息。 上述操作为 L-GW获知用户本地访问能力信息的可选方式。 另外, L-GW可以 本地配置用户本地访问能力信息。 用户本地访问能力信息包括: 用户本地访问业务接 入点名所绑定的闭合用户组标识信息、用户本地访问业务所支持的基站标识 /地址集合 信息等可以标识用户本地访问业务支持范围的信息。 所述用户本地访问业务可以是当 前已激活的业务也可以是用户所签约的所有本地访问业务。 步骤 702, 源家庭基站根据用户上报的测量报告发现当前基站已经不能为用户继 续服务, 则选择目标基站发起切换。 如果选择的目标基站为家庭基站, 那么在切换请 求消息中除了携带目标基站的标识 /地址之外还要携带目标基站的 CSG标识信息。 步骤 703, 本地网关收到切换请求消息后, 获知其中的目标基站信息, 根据目标 基站的标识判定用户是否移动出本地家庭基站网络, 执行本地访问移动性判定。 具体 地, 由于一个 L-GW仅为一个本地家庭基站网络服务, 如果目标基站仍连接在 L-GW 上, 那么 L-GW即可判定用户切换后仍然位于本地家庭基站网络内, 本地访问移动性 可以支持, 反之则认为不能支持。 如果步骤 701中 L-GW获知了用户本地访问能力信息, 那么 L-GW可以进行本地 访问接入控制的判定, 反之则不能。 所述本地访问接入控制判定具体指判定用户在目 标基站下是否支持已激活的本地访问业务。 上述判定需要 L-GW根据目标基站标识 / 地址或者 CSG标识与获知的用户本地访问能力信息的比较获得。 如果目标基站标识 / 地址或者 CSG标识包括在用户本地访问能力信息中, 那么本地访问接入控制通过, 反 之则不通过。 本地访问接入控制判定在本发明中为可选方式, 它可能引发 L-GW对本 地访问连接的保持或者释放的判定。 场景一: 本地网关可以同时进行本地访问移动性和本地访问接入控制的判定; 如果本地网关判定用户在目标基站下无法支持本地访问移动性, 那么本地网关释 放本地访问连接; 如果本地网关判定用户在目标基站下无法支持本地访问接入, 那么本地网关释放 本地访问连接。 如果本地网关判定用户在目标基站下可以支持本地访问移动性并且支持本地访问 接入, 那么本地网关保持本地访问连接, 执行正常的切换过程。 场景二: 本地网关仅进行本地访问移动性的判定; 如果本地网关判定用户在目标基站下无法支持本地访问移动性, 那么本地网关释 放本地访问连接; 如果本地网关判定用户在目标基站下可以支持本地访问移动性, 那么本地网关保 持本地访问连接, 继续切换过程。 本地网关可以将此本地访问移动性判定结果通知核 心网移动性管理单元。 本实施例以 L-GW仅进行移动性判定为例进行说明, 由于判断后的处理方式可以 覆盖场景一, 所以不做场景一处理的重复描述。 因此, 本实施例中如果 L-GW判定允许本地访问移动性, 则保持本地访问连接, 继续后续的切换过程。 在切换消息中指示 SGSN执行本地访问接入控制, 具体操作见 步骤 704 706。 如果 L-GW判定不允许本地访问移动性, 则释放本地访问连接, 具体 操作见步骤 707 715。 步骤 704, 本地网关在切换请求消息中携带本地访问移动性判定结果, 该条消息 通过家庭基站网关转发给 SGSN。 本地访问移动性判定结果用以通知核心网移动性管 理单元用户未移动出本地家庭基站网络, 指示核心网移动性管理单元开启本地访问接 入控制判定。 本地访问移动性判定结果在实现上可以用显示的指示信息或者本地访问 参数 (如本地访问承载信息) 的有无进行表示。 步骤 705, 核心网移动性管理单元收到本地访问移动性判定结果后, 结合切换请 求中的目标基站信息 (如标识、 地址、 CSG标识等信息) 和本地访问签约信息进一步 执行本地访问接入控制判定, 核心网移动性管理单元根据判定结果对本地访问连接执 行维持或者释放操作。 如果 SGSN判定用户在目标基站下的本地访问接入不允许, 那么发起本地访问 PDN连接释放; 如果 SGSN判定用户在目标基站下的本地访问接入允许,那么继续执行切换过程。 步骤 706, 如果 SGSN发起了本地访问连接的释放, 那么 SGSN在向目标基站发 送的切换请求中不包括本地访问无线承载信息。 反之则执行正常的切换。 步骤 707, 结合步骤 703所述判定原则, 如果 L-GW判定不允许本地访问移动性 和 /或 L-GW判断本地访问接入控制失败 (场景一情况下执行), 则中断当前的切换过 程, 发起本地访问 PDN连接释放。 L-GW对本地访问 PDN连接释放的处理过程具体 有两种方式, 方式一参见步骤 708至步骤 711, 方式二参见步骤 712至步骤 715。 步骤 708, L-GW通过 Iu接口消息指示源家庭基站切换中止并在收到本地访问无 线承载释放消息时重新发起切换过程。 具体的实现可以采用切换拒绝消息、 下行传输 消息等现有消息携带原因值进行表征或者定义新的 Iu或者 Iuh接口消息进行表征。 步骤 709, L-GW发起本地访问 PDN连接释放过程。 步骤 710, SGSN收到本地访问 PDP上下文释放或者本地访问 PDN连接释放消息 后通过 RAB释放消息释放本地访问连接所对应的无线承载。 步骤 711, 源家庭基站在收到携带本地访问无线承载释放的消息后删除对应的无 线承载资源重新发起切换过程。 步骤 712, L-GW发起本地访问 PDN连接释放过程。 步骤 713, SGSN收到本地访问 PDP上下文释放或者本地访问 PDN连接释放消息 后通过 RAB释放消息释放本地访问连接所对应的无线承载。 步骤 714, L-GW收到携带本地访问无线承载释放的消息后修改 source to target container中的承载信息, 将本地访问无线承载删除。 步骤 715, L-GW继续中止的切换过程, 向核心网发送切换请求消息。 实施例 2 图 8是根据实施例 2的切换过程中本地访问连接的处理方法的流程图, 本实施例 以 3G网络的切换过程为例进行本地访问连接处理方法的说明, 具体如下: 步骤 801, 源家庭基站根据用户上报的测量报告发现当前基站已经不能为用户继 续服务, 则选择目标基站发起切换。 如果选择的目标基站为家庭基站, 那么在切换请 求消息中除了携带目标基站的标识 /地址之外还要携带目标基站的 CSG标识信息。 步骤 802, 本地网关收到切换请求消息后, 获取其中的目标基站信息, 根据目标 基站的标识判定用户是否移动出本地家庭基站网络, 执行本地访问移动性判定。 具体 地, 由于一个 L-GW仅为一个本地家庭基站网络服务, 如果目标基站仍连接在 L-GW 上, 那么 L-GW即可判定用户切换后仍然位于本地家庭基站网络内, 本地访问移动性 可以支持, 反之则认为不能支持。 本实施例中 L-GW也可选进行本地访问接入控制判 断, 与实施例一不同, 本地访问接入控制的判定需要与核心网网元进行交互。 场景一: 本地网关可以同时进行本地访问移动性和本地访问接入控制的判定; 如果本地网关判定用户在目标基站下无法支持本地访问移动性, 那么本地网关释 放本地访问连接; 如果本地网关判定用户在目标基站下可以支持本地访问移动性, 那么启动本地访 问接入控制判定的交互过程。 场景二: 本地网关仅进行本地访问移动性的判定; 此场景下的判定同实施例一的描述。 本实施例以场景一 (L-GW同时进行移动性和接入控制的判定) 为例进行说明。 步骤 803, L-GW与 SGSN交互执行本地访问接入控制判定的信息和判定结果。 实现上可以在 Iu接口上新定义一对交互消息或者扩充现有的切换交互消息(如切换请 求、 切换响应 /拒绝等), L-GW将目标基站的 CSG标识信息发送给 SGSN, SGSN根 据本地访问签约信息判定后将用户是否在目标基站仍能支持已激活的本地访问连接的 结果回复给 L-GW, 或者 L-GW通过交互消息向 SGSN获取用户本地访问能力信息, 由 L-GW根据步骤 703所述方式进行本地访问接入控制的判定。 步骤 804, 如果 L-GW判定用户在目标基站下既能够支持本地访问移动性又能够 支持已激活的本地访问接入, 那么执行正常的切换过程。 步骤 805, 如果 L-GW判定用户在目标基站下能支持本地访问移动性但本地访问 接入控制不允许, 则执行本地访问连接释放过程。
L-GW对本地访问 PDN连接释放的处理过程具体有两种方式, 方式一参见步骤 806至步骤 811, 方式二参见步骤 812至 817。 具体执行过程参见实施例一。 实施例一和实施例二两种实施例的发明思想同样也可以适用于 LTE网络, 区别在 于信息传递所采用的接口消息不同, 应同等在本发明保护之内。 另外, 在 LTE网络中 He B GW可选部署, 不会影响本发明的使用。 实施例 3 图 9是根据实施例 3的切换过程中本地访问连接的处理方法的流程图, 本实施例 以 3G网络的切换过程为例进行本地访问连接处理方法的说明, 本实施例与实施例一 的区别在于本地访问移动性和 /或本地访问接入控制的判定由家庭基站网关完成。本地 访问连接的释放由家庭基站网关指示核心网移动性管理单元 SGSN完成。 家庭基站网 关与实施例一中的本地网关类似需对中止切换进行处理。 具体流程如下: 步骤 901, 在用户进入连接状态时, SGSN通过 Iu接口消息 (RAB指派消息、 下 行传输消息或者切换请求消息) 将用户本地访问能力信息下发给无线侧网元, 由于家 庭基站网关部署在 Iu接口上, 因此家庭基站网关可以获知这一信息。 上述操作为家庭 基站网关获知用户本地访问能力信息的可选方式。 另外, 家庭基站网关也可以本地配 置用户本地访问能力信息。 用户本地访问能力信息包括: 用户本地访问业务接入点名 所绑定的闭合用户组标识信息、用户本地访问业务所支持的基站标识 /地址集合信息等 可以标识用户本地访问业务支持范围的信息。 所述用户本地访问业务可以是当前已激 活的业务也可以是用户所签约的所有本地访问业务。 步骤 902, 源家庭基站根据用户上报的测量报告发现当前基站已经不能为用户继 续服务, 则选择目标基站发起切换。 如果选择的目标基站为家庭基站, 那么在切换请 求消息中除了携带目标基站的标识 /地址之外还要携带目标基站的 CSG标识信息。 切 换请求消息通过本地网关转发至家庭基站网关。 步骤 903, 由于家庭基站的注册消息均是通过 L-GW转发给家庭基站网关进行注 册的, 因此家庭基站网关能够得知 L-GW与下属家庭基站的配置关系。 家庭基站网关 收到切换请求消息后, 获取目标基站标识, 根据消息中的目标基站标识判定用户是否 移动出本地家庭基站网络, 执行本地访问移动性判定, 也即是否移动后仍在同一个 L-GW服务区内。 具体地, 由于一个 L-GW仅为一个本地家庭基站网络服务, 如果目 标基站仍连接在 L-GW上, 那么 L-GW即可判定用户切换后仍然位于本地家庭基站网 络内, 本地访问移动性可以支持, 反之则认为不能支持。 如果步骤 901中家庭基站网关获知了用户本地访问能力信息, 那么家庭基站网关 可以进行本地访问接入控制的判定, 反之则不能。 所述本地访问接入控制判定具体指 判定用户在目标基站下是否支持已激活的本地访问业务。 上述判定需要家庭基站网关 根据目标基站标识 /地址或者 CSG标识与获知的用户本地访问能力信息的比较获得。 如果目标基站标识 /地址或者 CSG标识包括在用户本地访问能力信息中, 那么本地访 问接入控制通过, 反之则不通过。 本地访问接入控制判定在本发明中为可选方式, 它 可能引发家庭基站网关对本地访问连接的保持或者释放的判定。 场景一:家庭基站网关可以同时进行本地访问移动性和本地访问接入控制的判定; 如果家庭基站网关判定用户在目标基站下无法支持本地访问移动性, 那么家庭基 站网关中止切换过程, 通知核心网移动性管理单元 SGSN释放本地访问连接; 如果家庭基站网关判定用户在目标基站下无法支持本地访问接入, 那么家庭基站 网关中止切换过程, 通知核心网移动性管理单元 SGSN释放本地访问连接。 如果家庭基站网关判定用户在目标基站下可以支持本地访问移动性并且支持本地 访问接入, 那么家庭基站网关保持本地访问连接, 执行正常的切换过程。 场景二: 家庭基站网关仅进行本地访问移动性的判定; 如果家庭基站网关判定用户在目标基站下无法支持本地访问移动性, 那么家庭基 站网关中止切换过程, 通知核心网移动性管理单元 SGSN释放本地访问连接; 如果家庭基站网关判定用户在目标基站下可以支持本地访问移动性, 那么家庭基 站网关保持本地访问连接, 继续切换过程。 家庭基站网关可以将此本地访问移动性判 定结果通知核心网移动性管理单元。 本实施例以家庭基站网关仅进行移动性判定为例进行说明, 由于判断后的处理方 式可以覆盖场景一, 所以不做场景一处理的重复描述。 因此, 本实施例中如果家庭基站网关判定允许本地访问移动性, 则保持本地访问 连接, 继续后续的切换过程。 在切换消息中指示 SGSN执行本地访问接入控制, 具体 操作见步骤 904 906。 如果家庭基站网关判定不允许本地访问移动性, 则中止切换过 程, 指示 SGSN释放本地访问连接, 具体操作见步骤 907 917。 步骤 904, 家庭基站网关在切换请求消息中携带本地访问移动性判定结果, 该条 消息发送给 SGSN。 本地访问移动性判定结果用以通知核心网移动性管理单元用户未 移动出本地家庭基站网络, 指示核心网移动性管理单元开启本地访问接入控制判定。 本地访问移动性判定结果在实现上可以用显示的指示信息或者本地访问参数 (如本地 访问承载信息) 的有无进行表示。 步骤 905, 核心网移动性管理单元 SGSN收到本地访问移动性判定结果后, 结合 切换请求中的目标基站信息 (如标识、 地址、 CSG标识等信息) 和本地访问签约信息 进一步执行本地访问接入控制判定, 核心网移动性管理单元 SGSN根据判定结果对本 地访问连接执行维持或者释放操作。 如果 SGSN判定用户在目标基站下的本地访问接入不允许, 那么发起本地访问 PDN连接释放; 如果 SGSN判定用户在目标基站下的本地访问接入允许,那么继续执行切换过程。 步骤 906, 如果 SGSN发起了本地访问连接的释放, 那么 SGSN在向目标基站发 送的切换请求中不包括本地访问无线承载信息。 反之则执行正常的切换。 步骤 907, 结合步骤 903所述判定原则, 如果家庭基站网关判定不允许本地访问 移动性和 /或家庭基站网关判断本地访问接入控制失败 (场景一情况下执行), 则中断 当前的切换过程, 指示 SGSN发起本地访问 PDN连接释放。本地网关中止切换, 指示 SGSN进行本地访问 PDN连接释放的处理过程具体有两种方式, 方式一参见步骤 908 至步骤 912, 方式二参见步骤 913至步骤 917。 步骤 908, 家庭基站网关指示 SGSN释放本地访问连接, 具体实现可以在上行 Iu 消息 (上行传输消息、 承载释放消息、 切换请求消息等) 中携带指示或者单独定义 Iu 接口消息用以表征。 步骤 909, SGSN发起本地访问 PDN连接释放过程。 步骤 910, 家庭基站网关在指示 SGSN释放本地访问连接时中止切换过程, 通过
Iu接口消息指示源家庭基站切换中止并在收到本地访问无线承载释放消息时重新发起 切换过程。 具体的实现可以采用切换拒绝消息、 下行传输消息等现有消息携带原因值 进行表征或者定义新的 Iu/Iuh接口消息进行表征。 需要说明的是步骤 908和步骤 910的消息触发并没有先后顺序的规定。 步骤 911, SGSN通过 RAB释放消息释放本地访问连接所对应的无线承载。 步骤 912, 源家庭基站在收到携带本地访问无线承载释放的消息后删除对应的无 线承载资源重新发起切换过程。 步骤 913, 家庭基站网关在指示 SGSN释放本地访问连接时自身中止切换过程。 指示 SGSN释放本地访问连接的操作同步骤 908。 步骤 914, 同步骤 909。 步骤 915, 同步骤 911。 步骤 916, 家庭基站网关收到携带本地访问无线承载释放的消息后修改 source to target container中的承载信息, 将本地访问无线承载删除。 步骤 917, 家庭基站网关继续中止的切换过程, 向核心网发送切换请求消息。 实施例 4 图 10是根据实施例 4的切换过程中本地访问连接的处理方法的流程图, 以 3G网 络的切换过程为例进行本地访问连接处理的方法说明, 本实施例与实施例三的区别在 于本地访问连接释放由家庭基站网关指示本地网关完成。 本实施例中仅描述与实施例 三不同的部分。 该流程具体如下: 步骤 1009,家庭基站网关采用类似步骤 907所述原则进行本地访问移动性和 /或本 地访问接入控制判定。 在判定不允许的情况下中断当前切换过程, 指示 L-GW发起本 地访问 PDN连接释放。 步骤 1008、 步骤 1013, 家庭基站网关指示 L-GW释放本地访问连接, 具体实现 可以在下行 Iu消息(下行传输消息、切换响应 /拒绝等)中携带指示或者单独定义 Iu/Iuh 接口消息用以表征。 实施例 5 图 11是根据实施例 5的切换过程中本地访问连接的处理方法的流程图,本实施例 以 3G网络的切换过程为例进行本地访问连接处理的方法说明, 本实施例与实施例三 的区别在于家庭基站网关对本地访问移动性和本地访问接入控制判定的处理方式不 同。 流程具体如下: 步骤 1102, 由于家庭基站的注册消息均是通过 L-GW转发给家庭基站网关进行注 册的, 因此家庭基站网关能够得知 L-GW与下属家庭基站的配置关系。 家庭基站网关 收到切换请求消息后, 获取目标基站标识, 根据消息中的目标基站标识判定用户是否 移动出本地家庭基站网络, 执行本地访问移动性判定, 也即是否移动后仍在同一个 L-GW服务区内。 具体地, 由于一个 L-GW仅为一个本地家庭基站网络服务, 如果目 标基站仍连接在 L-GW上, 那么 L-GW即可判定用户切换后仍然位于本地家庭基站网 络内, 本地访问移动性可以支持, 反之则认为不能支持。 本实施例中家庭基站网关也 可选进行本地访问接入控制判断, 判断方式与实施例二类似, 需要与核心网网元进行 交互。 场景一:家庭基站网关可以同时进行本地访问移动性和本地访问接入控制的判定; 如果家庭基站网关判定用户在目标基站下无法支持本地访问移动性, 那么家庭基 站网关中止切换, 指示 SGSN释放本地访问连接; 如果家庭基站网关判定用户在目标基站下可以支持本地访问移动性, 那么启动本 地访问接入控制判定的交互过程。 场景二: 家庭基站网关仅进行本地访问移动性的判定; 此场景下的判定同实施例三。 在此不做赘述。 本实施例以场景一 (家庭基站网关同时进行移动性和接入控制的判定) 为例进行 说明。 步骤 1103, 家庭基站网关与 SGSN交互执行本地访问接入控制判定的信息和判定 结果。 实现上可以在 Iu接口上新定义一对交互消息或者扩充现有的切换交互消息(如 切换请求、 切换响应 /拒绝等), 家庭基站网关将目标基站的 CSG标识信息发送给 SGSN, SGSN根据本地访问签约信息判定后将用户是否在目标基站仍能支持已激活的 本地访问连接的结果回复给家庭基站网关, 或者家庭基站网关通过交互消息向 SGSN 获取用户本地访问能力信息,由家庭基站网关根据步骤 1103所述方式进行本地访问接 入控制的判定。 步骤 1104, 如果家庭基站网关判定用户在目标基站下既能够支持本地访问移动性 又能够支持已激活的本地访问接入, 那么执行正常的切换过程。 步骤 1105, 如果家庭基站网关判定用户在目标基站下能支持本地访问移动性但本 地访问接入控制不允许, 则中止切换过程, 指示 SGSN执行本地访问连接释放过程。 具体的家庭基站网关中止切换过程, 指示 SGSN执行本地访问连接释放过程 (步 骤 1106至步骤 1115 ) 与实施例三中的步骤 1108〜步骤 1117相同, 在此不做赘述。 实施例 6 图 12是根据实施例 6的切换过程中本地访问连接的处理方法的流程图,本实施例 以 3G网络的切换过程为例进行本地访问连接处理的方法说明, 本实施例与实施例五 的区别在于本地访问连接释放由家庭基站网关指示本地网关完成。 本实施例中仅描述 与实施例五不同的部分, 具体如下: 步骤 1205, 家庭基站网关采用类似 1105所述原则进行本地访问移动性和 /或本地 访问接入控制判定。 在判定不允许的情况下终端当前的切换过程, 指示 L-GW发起本 地访问 PDN连接释放。 步骤 1206、步骤 1211, 家庭基站网关指示 L-GW释放本地访问连接, 具体实现可 以在下行 Iu消息(下行传输消息、 切换响应 /拒绝等) 中携带指示或者单独定义 Iu/Iuh 接口消息用以表征。 本发明中将本地访问移动性 (用户是否移动出本地家庭基站网络) 和本地访问接 入控制 (用户在目标区域是否支持已激活的本地访问业务) 的释义区分开来, 对于其 他任何本地访问业务连续性的判定如果包括这两方面内容均包括在本发明之内, 不做 具体名词上的限定。 从以上的描述中, 可以看出, 本发明实施例提供的方案通过对现有网络设备、 本 地网关、 家庭基站网关进行技术增强后, 使得上述架构可以实现本地访问接入功能并 且能够支持本地家庭基站网络内移动性的要求, 同时对现有核心网的升级改造影响较 小, 易于实现。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布在多个计算装置所 组成的网络上, 可选地, 它们可以用计算装置可执行的程序代码来实现, 从而可以将 它们存储在存储装置中由计算装置来执行,或者将它们分别制作成各个集成电路模块, 或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样, 本发明不限 制于任何特定的硬件和软件结合。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
