本发明以下实施例描述的网络架构以及业务场景是为了更加清楚的说明本 发明实施例的技术方案, 并不构成对于本发明实施例提供的技术方案的限定, 本领域普通技术人员可知, 随着网络架构的演变和新业务场景的出现, 本发明 实施例提供的技术方案对于类似的技术问题, 同样适用。
下面以毫微微蜂窝小区 (Femtocell )技术为例进行说明。 Femtocell是一种低功耗无线接入点技术的泛称,使用授权许可的频谱,连 接无线终端, 例如可以是手机、 平板电脑等终端设备, 利用家庭住户的数字用 户线(Digital Subscriber Line, DSL), 线缆宽带接入方式接入移动运营商的 网络。
Femtocell系统应用的目的是解决一些信号难以覆盖的盲点区和阴影区,比 如隧道、 地下车库、 地下通道、 地下商场、 高层建筑物低层和顶层等区域, 还 可以解决商业中心、 交通要道、 娱乐中心、 会议中心的话务热点区域的信号覆 盖, 可以降低这些区域的通信阻塞率和改善通信质量, 也常部署于高层建筑的 中间层, 可以有效避免手机的频繁切换甚至掉话。
图 1示例性的给出了运用 Femtocell技术的家庭接入系统的一种架构。
如图 1所示, 用户设备可以接入家庭无线接入点, 例如: 家庭基站(Home NodeB, HNB)、 家庭演进基站 (Home evolved NodeB, HeNB )或者家庭非 3GPP 无线接入点 ( Home non-3GPP Wireless Access Point, Home non-3GPP WAP ) , 其中 3GPP是第三代合作伙伴计划, 即 3rd Generation Partnership Project 的筒称。 HNB为运行在 UMTS陆地无线接入网 (UMTS terrestrial radio access network, UTRAN ) 频语的家庭无线接入点, 其中 UMTS 是 Universal Mobile Telecommunications System的筒称。 HeNB为运行在演进的 UMTS陆地无线接入 网 ( Evolved UMTS terrestrial radio access network, E-UTRAN ) 频谱的家 庭无线接入点。 Home non-3GPP WAP为运行在 non-3GPP网络频谱的家庭无线接 入点,其中 3GPP网络可以是码分多址接入(Code Division Multiple Access: CDMA ) 网络、 全球微波接入互操作性 (Worldwide Interoperability for Microwave Access, Wimax ) 网络、 无线局域网 (Wireless Local Area Network, WLAN) 网络或者高速包数据 (High Rate Packet Data, HRPD ) 网络等。 HNB和 HeNB在本申请统称为 H (e) NB
在图 1中, 家庭基站网关 (Home NodeB Gateway, HNB GW)、 家庭演进基站 网关 (Home evolved NodeB Gateway, HeNB GW )和家庭非 3GPP无线接入点网 关 ( Home non-3GPP Wireless Access Point Gateway, Home non-3GPP WAP GW) 是家庭无线接入点的网关网元, 分别通过通用 IP接入网络与 HNB、 HeNB和 Home non-3GPP WAP相连。 本领域普通技术人员可以理解在其他的家庭接入系统架构 中, 家庭无线接入点可以和移动网络中的网元直接相连。
图 1中还包括: E-UTRAN中的移动管理实体(Mobility Management Entity, MME)、 GPRS (General Packet Radio Service ) /UMTS中的服务 GPRS支持节点 ( Serving GPRS Supporting Node, SGSN )和匪- 3GPP网络中的非 3GPP网关。 non-3GPP网络中的非 3GPP网关, 可以是 WLAN中的演进分组数据网关(Evolved Packet Data Gateway, EPDG )、 Wimax中的接入业务网络网关 ( Access Service Network Gateway, ASN GW)、 C画 A 中的接入网关 (Access Gateway, AGW )及 HRPD中的高速包数据服务网关 (HRPD Serving Gateway, HSGW )等。
在图 1中,归属数据服务器可以是归属用户服务器( Home Subscriber Server. HSS )或者归属位置寄存器(Home Location Register, HLR ), 用于存储 UE 的 签约信息。 认证、 授权与计费服务器 ( Authentication Authorization and Accounting Server, AAA Server )用于对 UE执行接人认证、 4受权和计费功能。
为了限制 UE 接入特定的家庭无线接入点, 引入了封闭用户组 (Closed Subscriber Group, CSG )机制。 一个 CSG区域允许签约该 CSG的 UE接入, 对 未签约该 CSG的 UE限制接入。 一个 CSG区域以一个 CSG标识符 ( CSG ID )来标 识,每个 CSG区域包括一个或几个小区,同一 CSG区域的小区具有相同的 CSG ID。 对一个 UE而言,允许其接入的所有 CSG区域的 CSG ID构成一张该 UE的允许 CSG 列表(Allowed CSG List ), 也可称之为 CSG白名单( CSG White List ), 该 CSG 白名单包括在 UE的签约数据中和配置在 UE中。 当 UE接入网络后, 移动性管理 网元将从归属数据服务器获得 UE的签约数据,从而获知 UE的 Allowed CSG List 等信息,对 UE进行 CSG接入控制。其中,移动性管理网元可以是 MME或者 SGSN, 归属数据服务器可以是 HSS或者 HLR。
当 UE通过 H (e) NB接入时, UE可以通过 H (e) NB访问处于本地家庭基站网络 或者本地企业网络的其他 IP设备, 例如打印机或者传真机。 UE也可以采用与 LIPA类似的选择 IP数据流疏导( Selected IP Traffic Offload, SIPTO )技术来访问 特定的 IP网络,例如 Internet ,即通过 H (e) NB直接与 Internet进行数据传送。 在 UE使用 SIPT0技术进行业务时, UE需要建立一个 P匪连接, 称为 SIPTO PDN 连接。
为了更清楚的理解本发明实施例提供的技术方案, 下面以假设的某个企业 部署的 Femtoce l l为例, 其接入技术为 LTE, 相应的移动性管理网元为 MME。
本领域普通技术人员应当理解, 当接入网为 2G/ 3G 网络时, 无线接入点为 HNB, 移动性管理网元为 SGSN。
如图 2所示, 该企业包括区域 、 区域 B和区域 C, 属于同一个本地家庭基 站网络(Loca l Home Network, 筒称 LHN ), 分属不同的 CSG。 区域 A属于 CSG A, 区域 B属于 CSG B, 区域 C属于 CSG C。 区域 A包括 HeNB 141和 HeNB 142 , 区 域 B包括 HeNB 143和 HeNB 144,区域 C包括 HeNB 145和 HeNB 146。 区域 A的 HeNB 141和 HeNB 142接入 HeNB GW 111 , 区域 B的 HeNB 143和 HeNB 144接入 HeNB GW 112,区域 C的 HeNB 145和 HeNB 146接入 HeNB GW 113。 HeNB GW 111 与 HeNB GW 112接入移动性管理网元 101 , HeNB GW 113接入移动性管理网元 102。 区域 A、区域 B和区域 C的 HeNB都可接入企业内部 IP网络 121和 Interne t 122。 其中, 企业内部 IP网络 121包括打印机 131和传真机 132等设备。
如图 2所示, UE 151接入 HeNB 146,并通过 HeNB 146访问企业内部 IP网 络 121。 此时, 建立有 LIPA PDN连接 161。
如图 2所示, 当 UE 151在区域 C中移动, 从 HeNB146切换至 HeNB145的过 程中, 由于现有技术不支持 LIPA的移动性, 在切换过程中, LIPA P匪连接 161 将被去激活。
同样,如图 2所示,当 UE 151接入 HeNB 146,并通过 HeNB 146访问 Internet 122时, 建立有 S IPTO PDN连接 162。 UE 151从 HeNB 146切换至 HeNB 145的过 程中, 由于现有技术不支持 SIPT0的移动性, 在切换过程中, 该 S IPTO P匪连 接 162将被去激活。
为了使 LIPA P匪连接可以从源无线接入网元切换到目标无线接入网元, 如 图 3所示, 本发明实施例提供一种切换处理方法, 包括: 201 : 源移动性管理网元接收源无线接入网元发送的第一源到目标透明容 器, 该第一源到目标透明容器包括用户设备的 LIPA P匪连接的无线承载信息;
202: 该源移动性管理网元发送该第一源到目标透明容器和该 LIPA P匪连 接的无线接入 载信息至该目标无线接入网元。
本发明实施例及以下的实施例中, 无线承载信息是用户设备和无线接入网 元之间建立无线承载需要用到的信息, 包括无线资源控制容器或者切换类型等 信息。

图 3所示的方法通过发送包括 LIPA PDN连接的无线承载信息的源到目标 透明容器以及该 LIPA P匪连接的无线接入承载信息至目标无线接入网元, 使得 目标无线接入网元可以为用户设备的 LIPA P匪连接建立相应的承载, 能够实现 LIPA的移动性。
本发明实施例还提供一种源到目标透明容器处理方法, 如图 4所示, 包括: 301 : 源无线接入网元确定该源无线接入网元与目标无线接入网元在相同的 本地家庭基站网络;
302: 该源无线接入网元发送第一源到目标透明容器至源移动性管理网元, 该第一源到目标透明容器包括用户设备的本地 IP接入分组数据网 LIPA PDN连接 的无线承载信息。
图 4所示的方法通过确定目标无线接入网元与源无线接入网元在相同的本 地家庭基站网络, 满足用户设备的 LIPA P匪连接可以被切换到目标无线接入网 元的基本条件, 从而在发送给源移动性管理网元的第一源到目标透明容器中包 括用户设备的 LIPA P匪连接, 以便于源移动性管理网元可以将该第一源到目标 透明容器和 LIPA P匪连接的无线接入承载发送至目标无线接入网元来实现 LIPA 的移动性。

404: 匪 E 102判断 LIPA PDN连接 L1是否被许可接入 HeNB 144所在的 CSG; 其中, LIPA P匪连接 L1许可接入 HeNB 144所在的 CSG表示 LIPA P匪连接 L1可以在 HeNB 144保留。
示例性的, MME 102收到 HeNB 145发送的切换需求消息后, 获得 HeNB 144 所在 CSG的 CSG ID, 根据该 CSG ID和 UE 151的签约数据, 可获知 UE 151的 LIPA P匪连接 L1的接入点名称( APN )是否被许可在 HeNB 144所在的 CSG接入, 即允许在 CSG B接入。
若 LIPA P匪连接 L1的 APN被许可在 CSG B接入, 则执行 405 ;
可选的, 若 LIPA P匪连接 L1的 APN不被许可在 CSG B接入, 匪 E 102可以 去激活 LIPA P匪连接 Ll。 并且, 若 HeNB 145发送的切换需求消息中还包括第 二源到目标透明容器, 匪 E 102可以发送该第二源到目标透明容器和 UE 151的 非 LIPA P匪连接的无线接入承载信息至 HeNB 144以完成切换; 若 HeNB 145发 送的切换需求消息中不包括第二源到目标透明容器, 则拒绝切换, 示例性的, 匪 E 102 可发送切换请求失败消息至 HeNB 145。 其中, 可以通过源到目标透明 容器的名称来区别第一源到目标透明容器和第二源到目标透明容器。
405 : MME 102发送转发重定位请求消息至 MME 101 ;
其中,该转发重定位请求消息中包括第一源到目标透明容器和 P匪上下文, 该 P匪上下文中包括 UE 151的 LIPA PDN连接 L1的无线接入承载信息。 可选的, 若 UE 151还具有非 LIPA P匪连接, 则该第一源到目标透明容器 还可以包括 UE 151的非 LIPA P匪连接的无线承载信息, 此时, 该 P匪上下文 中同时包括 UE 151的非 LIPA P匪连接的无线接入承载信息。
406: 匪 E 101发送切换请求消息至 HeNB 144;
其中, 匪 E 101发送至 HeNB 144的切换请求消息中包括无线接入承载列表 和匪 E 101收到的第一源到目标透明容器。 该无线接入承载列表是根据匪 E 101 收到的 P匪上下文生成的, 因此该无线接入承载列表中包括 UE 151的 L I PA P匪 连接 L1的无线接入承载信息。可选的,若 P匪上下文中还包括 UE 151的非 LIPA P匪连接的无线接入承载信息, 则无线接入承载列表中也包括 UE 151的非 LIPA P匪连接的无线接入承载信息。

407: HeNB 144发送切换请求应答消息至 MME 101 ;
其中, HeNB 144收到第一源到目标透明容器和无线接入承载列表后, 可以 根据第一源到目标透明容器中的 LIPA P匪连接 L1 的无线承载信息和无线接入 承载列表中的 LIPA P匪连接 L1的无线接入承载信息为 LIPA P匪连接 L1建立 相应的承载。

502 : HeNB 144进行决策切换;
示例性的, HeNB 144根据测量报告确定需要切换到的目标无线接入网元为 HeNB 143。
503: HeNB 144判断与 HeNB 143是否在相同的本地家庭基站网络; 示例性的, HeNB 144可以通过 HeNB 144的本地配置, 或者 UE 151的上报, 或者与 HeNB 143的交互获得 HeNB 143所在的本地家庭基站网络的标识。 通过 判断 HeNB 144所在的本地家庭基站网络的标识是否与 HeNB 143所在的本地家 庭基站网络的标识, 可获知 HeNB 143与 HeNB 144所在的本地家庭基站网络是 否相同。 若 HeNB 144所在的本地家庭基站网络的标识与 HeNB 143所在的本地 家庭基站网络的标识相同, 则表示 HeNB 143与 HeNB 144所在的本地家庭基站 网络相同, 否则表示 HeNB 143与 HeNB 144所在的本地家庭基站网络不同。
若 HeNB 144与 HeNB 143在相同的本地家庭网络, 执行步骤 504 ;
可选的, 若 HeNB 144与 HeNB 143不在相同的本地家庭网络, 则 HeNB 144 去激活 LIPA P匪连接, 并可按照现有技术继续进行处理。 示例性的, 若 UE 151 只具有 LIPA PDN连接,或者只具有 LIPA PDN连接和 S IPTO PDN连接,则 HeNB 144 不发起切换; 若 UE 151还具有除了 LIPA P匪连接和 S IPTO P匪连接的其他的 P匪连接; 则 HeNB 144在发送至 MME 101的切换需求消息中携带源到目标透明 容器, 该源到目标透明容器包括 UE 151的除了 LIPA P匪连接和 S IPTO P匪连 接的其他的 P匪连接的无线承载信息, 以完成切换。 若 UE 151还具有 S IPTO PDN 连接, 在去激活 LIPA P匪连接时, 则还去激活 UE 151的 S IPTO P匪连接。
