Description

本地 I P接入或选定的 I P流量卸载的控制方法、 装置与系统
本申请要求于 2009 年 09 月 28 日提交中国专利局、 申请号为 200910110715.1、 发明名称为"本地 IP接入或选定的 IP流量卸载的控制方 法、 装置与系统"的中国专利申请的优先权, 其全部内容通过引用结合在本 申请中。 技术领域
本发明涉及通信领域,特别涉及一种本地 IP接入或选定的 IP流量卸载 的控制方法、 装置与系统。 发明背景
为了提供更高的数据传输速率和更小的时延, 同时降低运营商的运 营成本, 3GPP ( 3rd Generation Partnership Project,第三代合作伙伴计划) 提出了一种基于 H(e)NB ( Home (evolution) UTRAN NodeB , 家庭 (演进) 基站) 的接入服务。 家庭基站是一种小型的基站, 可以在家庭、 商场或 企业等场所部署,它可以实现宏基站的所有功能。 用户使用 UE ( User Equipment, 终端)通过 H(e)NB接入运营商核心网的同时,还可以接入到 家庭网络中与其他 IP设备互联,或通过 LIPA ( Local IP Access , 本地 IP接 入) 网络架构接入到 Internet网络中。 用于支持 LIPA的网络实体可以是 H(e)NB ,也可以是 H(e)NB GW( H(e)NB Gate Way,家庭 (演进)基站网关)。
随着数据业务的迅猛发展,用户数量不断增加,但运营商价值却不断 减少。 因此卸载 Internet业务的方式不仅仅可应用于家庭(演进)基站, 对 于宏网络的 Internet卸载 SIPTO(Selected IP Traffic Offload, 选定的 IP流量 卸载)功能也逐渐得到了 3GPP运营商的广泛关注。 SIPTO的主要作用是降 低运营商传输成本, 緩解核心网压力。 家庭用户 SIPTO功能的实现可以 通过家庭 (演进)基站或家庭 (演进)基站网关作为 IP业务的本地出口点; 宏 网络的 SIPTO功能主要由 RNC(Radio Network Controller, 无线网络控制 器)或 eNB (演进基站)作为 IP出口点得以实现。
UE通过 LIP A或 SIPTO架构接入 PDN ( Packet Data Network , 分组数 据网络)或 Internet时, 需要进行接入控制。 在现有技术中, 通过 HNB接 入的情形下, LIPA或 SIPTO的接入控制由 SGSN ( Serving General Packet Radio Service Support Node,服务通用分组无线网络业务支持节点)执行; 通过 HeNB接入的情形下, LIPA或 SIPTO的接入控制由 MME ( Mobility Management Entity, 移动性管理实体)执行。 由于这两种情形中接入控 制的过程类似, 而且所述 MME相当于所述 SG SN的控制面功能的分体, 在描述控制面功能时, 下文仅以 MME为例说明。 本领域技术人员可以理 解,在网络中部署的是 SGSN时, 其上的控制面功能就能够执行基本相同 的操作。 在现有技术中, 所述 LIP A接入控制的过程主要是:
1 ) MME通过 NAS ( Network Access Server, 网络接入服务器)信令, 接收来自 UE的接入请求, 当请求消息中的 APN ( Access Point Name , 接 入点名称)标识的是一个 Local IP APN (本地 IP接入 PDN连接的 APN )时, 网络将识别出该 UE请求的是一个 LIP A服务;
2 ) MME执行 LIP A的判断过程。
UE的签约数据中会维护一个网络是否授权 UE执行 LIPA的标识。 MME根据 UE的签约数据的 LIP A标识,检查网络是否允许 UE的 LIPA服务 请求, 如果网络允许 UE执行 LIPA, 则与 H(e)NB本地 IP相关的用户面数 据将转到 L-PGW ( Local PDN Gateway, 本地 PDN网关) , 建立 LIP A承 载。 若网络中部署的是 SGSN, 则与所述 L-PGW相应的网络实体为 L-GGSN ( Local Gateway General Packet Radio Service Support Node, 本 地网关 GPRS支持节点) 。 上述判断过程可以在附着、 联合附着、 分离、 位置更新、 业务请求等操作的过程中执行。
发明人发现, 在现有技术中, LIPA或 SIPTO控制的主要依据是 HSS 中维护的 UE的 LIPA签约数据, 而执行主体是核心网的功能实体, 这对核 心网的资源是一种不必要的侵占, 导致了系统的执行效率低下。 发明内容

为使本发明的目的、 技术方案和优点更加清楚明白, 下面结合实施方 式和附图, 对本发明做进一步详细说明。 在此, 本发明的示意性实施方式 及其说明用于解释本发明, 但并不作为对本发明的限定。
本发明实施例所公开的方法可以应用在如图 1或图 2所示的系统中。 其中图 1所示为采用 HNB的网络架构, 即 UMTS系统的网络结构; 图 2所 示为采用 HeNB的网络架构, 即 EPS系统的网络结构。 在图 1中,示出了 CSG cap. UE(具备 CSG能力的终端 W。non-CSG cap. UE (不具备 CSG能力的终端) ; 而在图 2中, 仅示出了 CSG cap. UE。 由 于本发明实施例中公开的技术方案涉及 LIPA或 SIPTO的控制, 其与终端 的 CSG能力有关系, 因此后文中提到的 UE, 在未作特别说明的情况下, 对其 CSG能力不做限定, 而交由判断过程进行判断。
图 1中示出的是 HNB, 可选的, 还可以有 HNB GW; 而在图 2中, 示 出的是 HeNB, 可选的, 还可以有 HeNB GW。 如前所述, 在本文中, 将 使用 H(e)NB或者基站来表示 HNB和 HeNB的统称, 使用 H(e)NB GW表示 HNB GW和 HeNB GW的统称。在本发明实施例中,除了可以使用 H(e)NB GW以外, 还可以使用与其具有类似功能, 例如 1^1?八或81?110能力、 基 站到核心网的汇聚功能、 数据转发功能等的其它接入网关设备。 因此, 本文也使用接入网关一词作为该类设备的统称, 而 H(e)NB GW仅作为一 种举例用于说明, 并不表示限定。 在网络中部署了 H(e)NB GW等接入网 关的情况下, H(e)NB和 SGSN或 MME之间通过 H(e)NB GW等接入网关进 行消息交互; 在网络中没有部署 H(e)NB GW等接入网关的情况下, H(e)NB和 SGSN或 MME之间直接进行消息交互。
如前所述, 和图 2所示的 MME可以认为是图 1所示的 SGSN的控制面 功能的分体, 而 S-GW则可以看作是 SGSN的用户面功能的分体。 在本发 明实施例中, 涉及到控制面功能描述的, 将以 MME作为举例, 或者使用 相应的中文名称"移动性管理实体"作为这类功能实体的统称。 而涉及到 用户面功能的描述时, 将以 S-GW ( Serving Gateway, 服务网关)作为举 例。 所述 S-GW如图 2所示, 具有提供 E-UTRAN和 EPC之间的分组路由、 移动性锚点、 网络发起的业务请求时的緩存、 合法侦听、 数据包的路由 等功能。 需要说明的是, 本领域技术人员不经过任何创造性劳动就可以 理解, 这种举例并不表示限定, 这种统称也是以功能描述作为实体名称, 其在不同的网络架构下仍应使用相应的名称。 图 1中所示的 MSC是移动交换中心 ( Mobile Switching Center ) ,其主 要为在其服务领域内漫游的移动电话提供电路交换呼叫、 移动管理及 GSM等服务。 其并不直接参与本发明实施例所述的方法的流程, 后文的 描述不予涉及。 但在整个通信网络中, 与本发明相关的某些操作可能涉 及 MSC的应用。 这些涉及 MSC的应用都可以按照现有技术操作, 本发明 实施例并不排除这些对 MSC的应用。
以 上 的 网 络 侧 实 体 属 于 VPLMM ( Visit Public Land Mobile-communication Network, 拜访公共陆地移动通信网 ) , 而接下来 要 介 绍 的 两 个 实 体 则 属 于 HPLMN ( Home Public Land Mobile-communication Network, 家乡公共陆地移动通信网) 。 图 1和图 2 中都示出了这两个实体。 HSS ( Home Subscriber Server, 归属签约用户 寄存器) 是 GPRS和 EPS ( Evolved Packet System, 演进分组系统) 用户 签约数据和路由信息永久的存放位置。
本发明实施例公开了一种本地 IP接入或选定的 IP流量卸载控制的方 法。 如图 3所示, 具体步骤包括: 本实施例中公开的方法, 具体由基站或接入网关完成 LIP A或 SIPTO 业务的接入控制。 该方法可以适用于图 1或图 2所示的网络架构。 其中, 接入网关是可选的。
基站本地维护 LIP A或 SIPTO允许成员列表, 所述列表用于列明允许 以 LIPA或 SIPTO方式接入的 UE的标识。 该列表可以用如 LIPA或 SIPTO Member List表示。 网络中部署有接入网关的, 该列表可选的可以维护在 接入网关的本地或者基站的本地。 本实施例给出该列表的两种可选的生 成方式, 作为举例的参考:
1 ) 根据运营商策略, 由策略服务器通过 OMA DM ( Open Mobile Alliance Device Management, 开放移动联盟终端管理协议)方式将 LIPA 或 SIPTO允许成员列表下发给基站或接入网关, 进一步的, 还可以利用
SIPT0允许成员的身份识别码列表中 UE的标识可以是 UE的身份识别码, 例^口可以是所述 UE的 IMSI ( International Mobile Subscriber Identity , 国 际移动用户识别码 ),或者 MSISDN( Mobile Subscriber Integrated Services Digital Network Number, 移动签约用户综合业务数字网号码) 。
2 )基站或接入网关所有者根据运营商策略在基站或接入网关本地生 成 八或 ^^^允许成员列表, 如1^1?八或81?110 ^1611 1^1" 1^ 基站或接 入网关所有者也可以对该表单进行成员浏览、 添加或删除等操作。 所述 入或 ^^) Member List中 UE的标识可以是 UE的 IMSI或 MSISDN。 步骤 302、 接收来自 UE的 LIPA或 SIPTO接入请求。 该 LIPA或 SIPTO 接入请求可以是一个单独的消息, 也可以是附着请求、 位置更新请求、 业务请求等等。 即所述 LIP A或 SIPTO接入控制过程可以是一个单独的过 程, 也可以是与其他过程结合在一起的。 若所述 LIP A或 SIPTO接入请求 过程与其他过程结合, 则相应的请求可以被看作是 LIP A或 SIPTO接入请 求。 例如, 若所述 LIP A或 SIPTO接入请求发生在附着过程中, 则附着请 求可以被看作是所述 LIP A或 SIPTO接入请求。 所述 LIPA或 SIPTO接入请 求中携带所述 UE的标识, 例如是所述 UE的 IMSI或 MSISDN。
步骤 303、 若所述 UE的标识, 例如所述 UE的 IMSI或 MSISDN , 在所 述 UE执行所述 LIPA或 SIPTO业务。
通过应用本实施例所述的方法, 基站或者接入网关本地维护 LIP A或 SIPTO允许成员列表, UE发起 LIP A或 SIPTO请求时, 向所述基站或接入 网关上报其标识,若所述 UE的所述标识在所述基站或接入网关本地维护 的 LIPA或 SIPTO允许成员列表中, 则允许所述 UE执行 LIPA或 SIPTO业 务。 这样, UE请求执行 LIP A或 SIPTO业务时, 系统无需每次执行接入控 制时都占用核心网资源, 而是由基站或者接入网关完成接入或 SIPTO控 制, 提高了系统的执行效率。
在所述 UE被允许执行所述 ? 或81?110业务之后, 网络侧需要为所 述UE建立LIPA或SIPTO承载。H(e)NB可以被设定为只允许特定的用户群 组接入。 这些被允许通过 H(e)NB接入的用户群组被称为 CSG ( Closed Subscriber Group , 限定用户群组) , 只允许 CSG驻留的小区成为 CSG小 区, 每个 CSG小区在所属的 PLMN ( Public Land Mobile-communication Network , 公共陆地移动通信网 ) 下都具有唯一的 CSG ID ( Closed Subscriber Group Indicator, 限定用户组标识) 。 对于一个终端来说, 可 以加入多个 CSG小区, 因此, 在终端和该终端所属的 HSS上都会维护一 份 ACL (Allowed CSG List, 允许限定用户组列表), 在 ACL中记录允许该 终端接入的所有 CSG小区的 CSG ID。 而图 1或图 2中所示的 CSG list server 的部署则是可选的, 用于为网络更新 ACL。 在 UE注册到网络中时, 所述 HSS会将 UE的签约数据发生到所述 MME上。 这样, 在现有技术中, 所述 MME在为所述 UE建立 LIP A或 SIPTO承载时, 还需要判断所述 UE所在的 CSG小区的 CSG ID是否在所述 UE的 ACL上。 若是, 才能为所述 UE建立 LIP A或 SIPTO承载, 若不是, 则不能为所述 UE建立 LIP A或 SIPTO承载。
然而, 并不是所有的基站, 例如 H(e)NB, 都具有作为 IP出口的能力。 若基站不具有这种能力, 则即便其允许所述 UE执行 LIP A或 SIPTO业务, 并且所述 UE所在的 CSG小区的 CSG ID也在所述 UE的 ACL上, 即核心网 为所述 UE建立了 LIPA或 载, 所述 UE仍然不能使用 LIPA或 SIPTO业务。 这样的话, 就可能造成核心网资源的浪费。
下面的实施例中, 除了以 LIP A或 SIPTO接入控制发生在附着过程为 例, 来说明本发明实施例公开的本地 IP接入控制的方法之外, 还对上面 实施例的方法进行了改进, 以进一步解决所述可能浪费核心网资源的问 题。 本实施例中公开的方法, 具体由基站或接入网关完成 LIP A或 SIPTO 业务的接入控制。 该方法可以适用于图 1或图 2所示的网络架构。 其中, 接入网关是可选的。
基站本地维护 LIP A或 SIPTO允许成员列表, 该列表可以用如 LIPA或 SIPTO Member List表示。 网络中部署有接入网关的, 该列表也可以维护 在接入网关的本地。 其中该列表的生成方式的举例可以参考前文中的相 应部分, 此处不再赘述。
进一步的, 基站或接入网关的本地上下文中还维护该基站或接入网 关的 LIP A或 SIPTO能力指示信息。 所述 LIPA或 SIPTO能力指示信息, 用 于指示所述基站或者接入网关具有 IP出口的能力。 具体的, 可以在基站 上下文中的基站无线接入能力(MS Radio Access Capability)字段中增加 该基站支持 LIP A或 SIPTO的能力指示信息, 所述 LIP A或 SIPTO能力指示 信息例如可以是 LBO ( Local Breakout, 本地出口) Indication
在基站或接入网关配置有上述信息的场景下, UE可以发起 LIPA或 SIPTO的承载建立请求。 具体的, 在本实施例中, 作为举例, UE的 LIPA 或 SIPTO承载可以采用下述两种方式中的任意一种实现。
方式一:核心网为被允许执行 LIP A或 SIPTO业务的 UE直接建立 LIPA 或 SIPTO承载, 具体可以参照图 4。
步骤 401、 UE发起附着请求消息给基站, 若网路中部署有接入网关, 则所述基站将所述附着请求消息转发给所述接入网关。 所述附着请求消 息可以是 Attach Request消息, 所述附着请求消息中携带所述 UE的 IMSI 或 MSISDN。
步骤 402、 所述基站或接入网关转发所述 UE的所述附着请求消息到 MME。所述附着请求消息中携带所述基站或接入网关地址,如 H(e)NB ID 或 H(e)NB-GW ID。
并且, 所述基站或接入网关根据所述 UE的所述 IMSI或 MSISDN进行 UE的 LIPA或 SIPTO接入控制。 如果所述 UE的 IM SI或 M SISDN在所述 LIP A或 SIPTO Member List中, 则允许所述 UE执行 LIP A或 SIPTO业务。
进一步的, 所述基站或接入网关的, 所述基站或者接入网关还要判 断其本地上下文中是否有 LIP A或 SIPTO能力指示信息。如果允许所述 UE 执行 LIP A或 SIPTO业务, 并且所述基站或接入网关上维护有 LIPA或 SIPTO能力指示信息, 如 LBO Indication, 则还向所述 MME发送 LIPA或 SIPTO确认指示, 该指示用于指示其能够为所述 UE提供 LIP A或 SIPTO接 入, 并且允许所述 UE以 LIP A或 SIPTO方式接入, 具体的, 可以用如 LIPA 或 SIPTO Indication表示。在向 MME发送时,所述 LIP A或 SIPTO Indication 可以携带在任意的 SI -MME信令中发送。 在 UMTS系统中, 则是向 SGSN 发送,此时所述 LIPA或 SIPTO Indication可以携带在任意的 Iu-ps信令中发 送。
步骤 403、所述 MME检查当前所述 UE请求接入的 CSG小区的 CSG ID 是否在所述 UE的 ACL中, 若所述 CSG ID在所述 UE的 ACL中, 且在 81-^1^1 信令中有1^?八或81?110 Indication信息, 则为所述 UE建立 LIPA 或 SIPTO承载。 所述 MME根据所述 UE所在的 LIP A或 SIPTO APN和基站 或接入网关地址, 为所述 UE选择其所在基站或接入网关的本地 PDN GW , 后文称为 L-PGW。 如前所述, 在 UMTS系统中, 所述 L-PGW相应 的是 L-GGSN。
在 EPS系统中, 所述 MME进一步向对应的 S-GW并发送建立缺省承 载请求消息。 所述建立缺省 载请求消息可以是 Create Default Bearer Request消息, 或者建立会话清求消息 Create Session Request消息。
步骤 404、 所述 S-GW在它的 EPS ( Evolved Packet System, 演进分组 系统)承载列表中创建一个入口, 并向所述 L-PGW发送建立缺省承载请 求消息。所述建立缺省承载请求消息可以是 Create Default Bearer Request 消息, 或者建立会话请求消息 Create Session Request消息。 在 UMTS系统 中, 由于 S-GW的相应功能也有 SGSN执行, 则由 SGSN执行本步骤。
步骤 405、 所述 L-PGW向所述 S-GW返回建立缺省承载响应消息。 所 述建立缺省 载响应消息可以是 Create Default Bearer Response消息, 或 者建立会话响应消息 Create Session Response消息。
步骤 406、 所述 S-GW向所述 MME返回建立缺省承载响应消息 。 可 以理解的, 在 UMTS系统中, 本步骤省略。
步骤 407、 所述 MME向所述基站或接入网关返回初始上下文建立请 求 /附着接受消息给基站或接入网关。 所述初始上下文建立请求消息 I附 着接受消息可以是 Initial Context Setup Request/ Attach Accept消息。
步骤 408、 所述基站或接入网关向所述 UE发送无线资源连接重配置 消息。 所述无线资源控制连接重配置消息可以是 RRC Connection Reconfiguration消息。
之后, 网络可以执行其他附着流程。例如具体可以参考 23.401 v9.0.0 协议中定义的附着流程。 所述 23.401协议为演进的通用陆地无线接入网 络接入的 GPRS增强协议。
方式二: 核心网为被允许执行 LIPA或 SIPTO业务的 UE下发 LIPA或 SIPTO指示, 收到指示的 UE可以后续发起 LIPA或 SIPTO业务, 建立 LIPA 或 SIPTO承载。 具体可以参照图 5。
步骤 501至步骤 502与步骤 401至步骤 402相同, 具体可以参考上文的 描述, 此处不再赘述。
步骤 503、 MME检查当前所述 UE请求接入的 CSG小区的 CSG ID是否 在所述 UE的 ACL中, 若所述 CSG ID在所述 UE的 ACL中, 且在 S 1-MME 信令中有 LIP A或 SIPTO Indication信息, 则向对应的 S-GW发送建立缺省 承载请求消息。 所述建立缺省承载请求消息可以是 Create Default Bearer Request消息, 或者建立会话清求消息 Create Session Request消息。
步骤 504至步骤 506与步骤 404至步骤 406相同, 此处不再赘述。 步骤 507、 所述 MME发送初始上下文建立请求 /附着接受消息给基站 或接入网关, 在该消息中携带 LIP A或 SIPTO Allowed指示。 所述 LIP A或 SIPTO Allowed指示为 LIP A或 SIPTO允许指示, 表示所述 UE此后可以凭 借此信息直接请求建立承载。 所述初始上下文建立请求消息 /附着接受消 步骤 508、 所述基站或接入网关向所述 UE发送无线资源连接重配置 消息, 该消息中携带所述 LIP A或 SIPTO Allowed指示。 所述无线资源控 制连接重配置消息可以是 RRC Connection Reconfiguration消息。
所述 UE根据所述 LIPA或 SIPTO Allowed指示后续可以发起 LIPA或 SIPTO业务请求,核心网可以为所述 UE建立 LIP A或 SIPTO承载。具体的, 所述 LIP A或 SIPTO承载的建立方法可以参考图 4及上述方式一中的描述。 所不同的是, 步骤 401中, 所述 UE在所述附着请求中携带所述 LIPA或 SIPTO Allowed; 步骤 402中, 所述基站或者接入网关直接将所述附着请 求中的所述 LIP A或 SIPTO Allowed发送给 MME。在步骤 403中,所述 MME 根据所述 LIP A或 SIPTO Allowed, 直接为所述 UE建立承载。
在上述发明实施例中, 基站或者接入网关本地维护 LIP A或 SIPTO允 许成员列表, UE发起附着请求消息给所述基站或所述接入网关, 所述附 着请求消息中携带所述 UE的 IMSI或 MSISDN。 若所述 UE的所述 IMSI或 MSISDN在所述基站或接入网关本地维护的 LIPA或 SIPTO允许成员列表 中, 则允许所述 UE执行 LIP A或 SIPTO业务。 进一步的, 在所述基站或接 入网关的本地上下文中还维护该基站或接入网关的 LIP A或 SIPTO能力指 示信息。 若所述 UE被允许执行 LIPA或 SIPTO业务, 且所述基站或接入网 关的本地上下文中维护有 LIP A或 SIPTO能力指示信息, 则向 MME发送 LIP A或 SIPTO确认指示 LIP A或 SIPTO Indication, 由所述 MME为所述 UE 建立 LIPA或 SIPTO承载, 或者将所述 LIPA 或 SIPTOIndication下发给所 立请求。 这样, UE请求执行 1^1?八或81?110业务时, 系统无需每次进行进 入控制时都占用核心网资源, 而是由基站或者接入网关完成接入或 SIPTO控制, 提高了系统的执行效率。 进一步的, 只有在所述基站或接 入网关具备 LIPA或 SIPTO出口能力时, 核心网才为所述 UE建立 LIPA或 SIPTO承载, 有效降低了核心网的资源浪费。
