Description

网元选择实体及用户设备注册的方法 技术领域
本发明涉及无线通信技术领域,特别涉及一种网元选择实体及用户设备注 册的方法。 背景技术
随着无线通信技术的迅速发展,通过网络处理的业务的种类和数量越来越 多。 例如在 4G网络时代, 为了满足用户的业务需求, 运营商通常会在网络中 布局多个 MME ( Mobility Management Entity, 移动管理实体)来分流用户和业 务。 因此, 当 UE ( User Equipment, 用户设备) 与 eNB ( evolved Node B, 演 进型基站) 建立连接时, 如果在连接过程中传递的消息中未携带已经注册的 MME的标识, 则 eNB需要选择一个 MME来服务 UE。
相关技术在选择 MME时, 通常釆用如下两种方式:
第一种方式: 运营商会预先通过管理 MME的 EMS ( Element Management System, 网元管理系统) 配置网络中各个 MME的权重, 并将各个 MME的权 重配置结果下发至 eNB。 在此基础上, 如果 UE连接 eNB时, 未通知 eNB其 已经注册的 MME的标识,则 eNB根据收到的权重配置结果选择一个 MME作 为月良务该 UE的 MME。
第二种方式: 在部署有虚拟运营商的 MME和传统运营商的 MME的核心 网中, eNB同时连接虚拟运营商的 MME和传统运营商的 MME, eNB会在空 口广播消息中携带虚拟运营商的网络标识和传统运营商的网络标识, 当 UE连 接 eNB时, UE会向 eNB返回其中一个网络标识, eNB会根据 UE返回的网络 标识为该 UE选择虚拟运营商的 MME或者传统运营商的 MME。

为了更清楚地说明本发明实施例中的技术方案, 下面将对实施例描述中所 需要使用的附图作简单地介绍, 显而易见地, 下面描述中的附图仅仅是本发明 的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下, 还可以根据这些附图获得其他的附图。 图 1是本发明一实施例提供的一种用户设备注册的方法所涉及的网络架构 示意图;
图 2是本发明另一实施例提供的一种网元选择实体的结构示意图; 图 3是本发明另一实施例提供的一种用户设备注册的方法的流程图; 图 4是本发明另一实施例提供的一种用户设备注册的方法的流程图; 图 5是本发明另一实施例提供的一种用户设备注册的方法的流程图。 具体实施方式
为使本发明的目的、 技术方案和优点更加清楚, 下面将结合附图对本发明 实施方式作进一步地详细描述。
当运营商通过在网络中布局多个 MMNE来分流用户和业务时, UE接入网 络后, 基站设备需要为 UE选择一个为该 UE服务的 MMNE。 然而, 针对相关 技术中在为 UE选择 MMNE时,是根据网络包括的每个 MMNE的权重选择某 个 MMNE。 釆用此种方法, 无法将具有一定特征的 UE选择到特定的 MMNE, 选择 MMNE的方式不够灵活。例如,根据每个 MMNE的权重选择可能不能实 现为 UE选择能够满足特殊业务的 MMNE。 针对相关技术中提供的第二种方 式,需要由 UE选择网络后,再在被选网络中选择一个 MMNE,使得选择 MMNE 的过程需要依赖于 UE, 导致选择 MMNE过程运营商难以管理, 不满足运营商 灵活管理网络的需求。 另外, 在第二种方式中, 由于基站需要通过空口广播网 络标识, 因此, 需要软件升级基站, 使其支持网络共享功能, 同时增加数据配 置, 因为基站数量庞大, 因此配置工作量也较大。 综上, 为了克服相关技术中 的问题, 本发明实施例提供的一种网元选择实体及用户设备注册的方法。
随着移动通信技术的高速发展, 为 UE选择灵活选择为其服务的 MMNE 的场景也日益增多, 例如以下 2种场景:
第一种场景: 随着无线通信技术的迅速发展, NFV ( Network Function Virtualisation, 网络功能虚拟化)技术已逐步成熟。 NFV后, 大部分运营商会 在已部署的物理网络的基础上利用现有的网络硬件设备再部署一个或多个虚 拟化网络, 并将虚拟化网络租借给其他的网络运营者。 本发明实施例中将运营 已有物理网络的运营商称为传统运营商, 将运营虚拟网络的运营者称为虚拟运 营商。 例如, 对于 LTE ( Long Term Evolution, 长期演进) 系统来说, 运营商 通常会在 EPC( Evolved Packet Core,演进分组核心网)的基础上建设一张 vEPC ( Virtual Evolved Packet Core, 虚拟演进分组核心网), 并使用该 vEPC分流现 网用户和业务。 如, 可以分配运营商自己的用户选择到 EPC, 使用 EPC为传 统运营商的用户月良务, 而分配 MVNO ( Mobile Virtual Network Operator, 移动 虚拟网络运营商)的用户选择到 vEPC, 使用 vEPC为虚拟运营商的用户服务。 因此, 在传统网络的基础上部署虚拟化网络后, 当 UE接入网络后, 基站设备 需要从 EPC或 vEPC包括的 MMNE中灵活选择一个 MMNE来服务 UE。
第二种场景: 针对未叠加虚拟化网络, 例如, 只包含 EPC 的情况, 运营 商有时候需要分配某些 MMNE处理特定业务。 在 UE接入网络后, 为了使该 UE能够完成特定的业务, 基站设备需要为该 UE选择能够处理该特定业务的 服务 MMNEo
为了实现 MMNE的灵活选择, 本发明实施例提供了一种网元选择实体和 用户设备注册的方法, 具体详见以下内容。
如图 1所示, 其示出了本发明实施例提供的用户设备注册的方法所涉及的 网络架构示意图。 图 1所示的网络架构为一个部署有虚拟化网络的 LTE系统, 该 LTE系统包括至少一个 UE、 至少一个基站设备 (在 LTE系统中为演进的节 点:^ 英文为 evolved node B, 简称为 eNB )、 网元选择实体、 至少一个移动管 理实体 MME设备、 至少一个 SGW ( serving network gateway, 服务网关)和 PGW( packet data network gateway,分组数据网网关)设备(其中 , SGW和 PGW 可以集成在一个物理设备上,通常用 SGW/PGW表示,也可以用 S/PGW表示)、 HSS ( Home Subscriber Server, 归属用户服务器)设备、 网元管理系统 EMS 设备以及虚拟服务设备。 其中, 至少一个 MME、 至少一个 S/PGW及 HSS构 成了 LTE系统的演进型分组核心网 ( evolved packet core, 简称 EPC ); 虚拟月良 务设备上提供了一个虚拟 EPC (简称 vEPC ) ,该 vEPC 包括至少一个虚拟的 MME (简称 vMME )、 至少一个虚拟的 S/PGW (简称 vS/PGW )和至少一个虚 拟的 HSS (简称 vHSS ), EPC和 vEPC都和 eNB相连。 EMS为能够管理各个 网元正常工作的服务器。 另外, 无论是对于 EPC, 还是对于 EPC和 vEPC同时 存在的 LTE系统,为了更好地提供服务,同时也为了减小各个网元之间的负载, EPC或 EPC和 vEPC共同组成的网络中可以部署多个 MME或多个 S/PGW, 从而形成 POOL (池)。 在图 1中, 各网元的标识后面的 "s" 即表示网络中可 以包括多个该网元, 且每种网元之间形成网元池。 例如, MME之间形成 MME POOL, SGW之间形成 SGW POOL, PGW之间形成 PGW POOL, 等等。 在图 1所示的 LTE系统中, 网元选择实体和 eNB互联, 网元选择实体和 EMS互联。
图 1所示的网络架构仅仅作为一种举例, 其他的网络场景例如 2G和 3G 的网络架构同样适用于本发明实施例。为了便于描述,本发明将 MME和 SGSN 统称为移动性管理网元( Mobility Management Network Element, 简称 MMNE ), 将接入网中提供基站服务的 eNB、 RNC、 BSC等接入网设备统称为基站设备, 其中为 UE提供服务的基站设备,称为服务基站设备,为 UE提供服务的 MMNE 称为月良务 MMNE。
在本发明实施例中, 网元选择实体主要用于为 UE选择服务 MMNE。 为了 能够提高选择服务 MMNE的灵活性, 可以考虑通过设置 UE的用户信息和候 选 MMNE的对应关系来实现为不同特征的 UE选择不同的服务 MMNE。因此, 在网元选择实体为 UE选择服务 MMNE时,可以获取 UE的用户信息和候选服 务 MMNE的对应关系来决定选择哪个 MMNE为该 UE服务。该对应关系可以 预先配置在网元选择实体上, 也可以存储在其他网元上, 由网元选择实体从该 其他网元获取。 例如, 在网元选择实体上可以设置一个服务 MMNE选择策略 库, 在该库中保存用户信息和候选服务 MMNE的对应关系, 或者在其他网元 上设置该服务 MMNE选择策略库。用户信息和候选服务 MMNE的对应关系的 存储方式有多种, 例如, 在一张存储表中的一行记录中存储用户信息和候选服 务 MMNE的标识; 再例如, 在一张存储表中的一行记录中存储用户信息和候 选服务 MMNE的类型,在另一张存储表中存储候选服务 MMNE的类型和多个 候选 MMNE的对应关系,本发明实施例对用户信息和候选服务 MMNE的对应 关系的存储方式不作限定。
通常, UE在附着流程或者在由改变当前服务 MMNE引发的位置更新的流 程中, 基站设备会为该 UE选择服务 MMNE, 以使 UE注册到该服务 MMNE。 在本发明实施例中,将能够使 UE注册到服务 MMNE的流程称为 UE向 MMNE 注册的注册流程。 因此, 本发明实施例中附着流程和位置更新流程统称为注册 流程。本领域技术人员应知, UE向 MMNE注册的注册流程不限于附着流程和 位置更新流程, 本发明实施例对此不作限定。 通常在注册流程前, UE与基站 设备需要建立无线资源控制 (Radio Resource Control, 简称 RRC )连接, 当在 RRC连接建立过程中, 若 UE向基站设备发送之前注册过的 MMNE的信息, 基站设备会优先为该 UE选择之前注册过的 MMNE作为服务 ΜΜΝΕ, 若 UE 没有向基站设备发送之前注册过的 MMNE的信息, 基站设备通常会根据权重 为该 UE选择服务 MMNE。
为了避免对基站设备的改动, 可以考虑利用上述注册流程来实现本发明的 目的。 为了实现这一目的, 可以在基站设备和网元选择实体之间的接口协议可 以釆用基站设备和 MMNE之间的接口协议, 例如 S 1接口协议, Gb接口协议 或者 Iu接口协议。 这样, 当在 RRC连接建立过程中, 在 UE没有向基站设备 发送之前注册过的 MMNE的信息的情况下, 网元选择实体在基站设备为 UE 选择服务 MMNE的时候, 有机会作为 UE的服务 MMNE而被选中, 从而可以 接收 UE的附着请求消息或者位置更新消息, 并可以在附着流程和位置更新流 程中根据 UE 的用户信息和候选服务 MMNE 的对应关系为 UE 选择服务 MMNE。进一步, 为了能够提高网元选择实体被选中作为服务 MMNE的概率, 可以将网元选择实体的权重设置为 100%, 其他 MMNE设置为 0。 对于 UE之前未在其他 MMNE上注册的情况, 在 RRC连接建立过程中, UE不会向基站设备发送之前注册的 MMNE的信息,因此可以通过上述方法实 现将 UE注册到网元选择实体来实现本发明的目的。 对于 UE已经注册在其他 MMNE上的情况, 可以考虑指示 UE在 RRC连接建立过程中不携带已注册的 MMNE的信息来实现将 UE注册到网元选择实体。 例如在 LTE网络中, 可以 发送携带原因值为 Load Balancing TAU Required的用户设备上下文释放命令消 息, 收到该消息后, UE会发起位置更新流程, 在与基站设备建立 RRC连接时 不会携带已注册的 MMNE的信息。
综上, 通过利用上述注册流程, 可以将网元选择实体作为服务 MMNE (这 里称为第一服务 MMNE ), 使 UE注册到该网元选择实体, 再由网元选择实体 根据用户信息和候选服务 MMNE的对应关系为 UE选择一个服务 MMNE (这 里称为第二 MMNE )。
在网元选择实体为 UE选择 (也可以称为确定) 第二 MMNE后, 可以利 用全球统一全球唯一用户设备临时标识 GUTI分配机制和隐式分离机制, 实现 UE向第二 MMNE的注册。
在网元选择实体为 UE选择第二 MMNE后, 网元选择实体获取属于第二 MMNE的 GUTI资源, 从该 GUTI资源中选择一个 GUTI, 利用附着流程或者 位置更新流程将该 GUTI分配给 UE。 其中, 属于第二 MMNE的 GUTI会包括 第二 MMNE的标识。 UE在收到分配的 GUTI后,会认为已经注册到第二 MMNE 上。 接着, 网元选择实体可以在附着流程或者位置更新流程后发起对该 UE的 隐式分离, 当 UE再次和基站设备建立 RRC连接时, 会将之前已经注册到的 第二 MMNE的标识发送给基站设备, 基站设备会根据该标识为该 UE选择第 二 MMNE作为服务 MMNE, 从而实现了 UE注册到网元选择实体为其选择的 服务 MMNE上。
进一步的, 为了避免第二 MMNE分配的 GUTI和网元选择实体分配的属 于第二 MMNE的 GUTI相同造成冲突, 在具体实现的时候, 第二 MMNE可分 配的 GUTI资源和网元选择实体可分配的属于第二 MMNE的 GUTI资源不重 复。
图 1仅示出了 LTE系统中的具体结构,上述内容也仅以为 UE选择 MMNE 的方法适用于 LTE系统为例进行了举例说明。 然而, 在具体实施时, 本发明实 施例提供的方法同样可以适用于 2G/3G系统中。其中, 由于本发明实施例提供 的方法同时适用于 2G/3G等各种系统,因此,本发明实施例中所涉及的 MMNE 可以为 MME, 也可以为 SGSN, 等等。 图 2是根据一示例性实施例示出的一种网元选择实体, 该网元选择实体用 于执行下述图 3 至图 5 所示实施例中任一实施例中网元选择实体所执行的功 能。 该网元选择实体由 UE的服务基站设备选择作为 UE的第一服务 MMNE。 参见图 2, 该网元选择实体包括:

本发明实施例提供的方法, 通过 UE的用户信息与候选服务 MMNE的对 应关系为 UE选择服务 MMNE, 能够实现为具备某一特征的 UE选择特定的 MMNE, 较现有技术提高了 MMNE选择的灵活性。 由于可以通过修改用户信 息与候选服务 MMNE的对应关系, 使得运营商能够根据不同的策略为 UE选 择 MMNE, 方便了运营商进行网络管理。 图 4是根据一示例性实施例示出的一种用户设备注册的方法的流程图。在 该实施例中, 以网元选择实体为新开户用户对应的 UE选择一个服务 MMNE 为例, 对本发明实施例提供的方法进行详细地解释说明。 其中, 网元选择实体 为服务基站设备选择作为 UE的第一服务 MMNE的实体。 参见图 4, 本发明实 施例提供的方法流程包括:
401 : UE与服务基站设备建立 RRC连接。
为了触发 UE接入核心网, UE需要与服务基站设备建立 RRC连接。 关于 UE与服务基站设备建立 RRC连接的过程, 本发明实施例不作具体限定。 具体 实施时, UE与服务基站设备建立 RRC连接的过程为: UE向服务基站设备发 送 RRC连接建立请求; 服务基站设备接收该 RRC连接建立请求, 并在确定接 受 UE的 RRC连接后, 向 UE返回 RRC连接建立响应; UE接收该 RRC连接 建立响应, 并向服务基站设备回复 RRC连接完成消息来实现与服务基站设备 建立 RRC连接。
通常, 已经在网络驻留的 UE会在 RRC连接完成消息中通知服务基站设 备已经注册的 MMNE的标识, 即 RegisteredMMNE的标识。 这种情况下, 月良 务基站设备会才艮据已经注册的 MMNE的标识选择已经注册的 MMNE的标识对 应的 MMNE作为服务 UE的 MMNE。 然而, 由于本发明实施例针对新开户用 户对应的 UE, 亦即未曾在任何 MMNE驻留的 UE, 因此, 该 UE在 RRC连接 建立阶段中的 RRC 连接完成消息中不会通知服务基站设备其已经注册的 MMNE的标识。
其中, 本发明实施例不对 UE及服务基站设备的具体类型进行限定。 具体 实施时, UE包括但不限于为平板电脑、 手机、 PC ( Personal Computer, 个人 计算机),等等。服务基站设备包括但不限于为 RNC( Radio Network Controller, 无线网络控制器)、 BSC ( Base Station Controller, 基站控制器)、 eNB等 402: 服务基站设备选择网元选择实体作为 UE的第一服务 MMNE。
在本发明实施例中,由于 UE与服务基站设备建立 RRC连接时 UE未通知 服务基站设备其已经注册的 MMNE 的标识, 因此, UE与服务基站设备建立 RRC连接后, 为了给 UE选择一个服务 MMNE, 需要使服务基站设备与能够 为 UE分配 MMNE 的一个网元建立连接, 确保可以由该网元为 UE分配一个 MMNE。 然而, 为了解决现有技术中出现该种情况时, 直接由服务基站设备根 据网络中各个 MMNE 的权重随机连接到某个 MMNE 上而造成的选择目标 MMNE 的方式不够灵活的问题, 本发明实施例提供的方法预先设置一个网元 选择实体。如果 UE与服务基站设备建立 RRC连接时 UE未通知服务基站设备 其已经注册的 MMNE的标识, 则服务基站设备选择网元选择实体作为 UE的 第一服务 MMNE, 由网元选择实体根据预先存储的用户信息和至少一个候选 服务 MMNE的对应关系确定为 UE选择的第二服务 MMNE。
关于网元选择实体的具体结构,本发明实施例不作具体限定。具体实施时, 网元选择实体可以为包括至少一个 MMNE的实体。 可选地, 网元选择实体还 可以为包括至少一个 S/PGW等的实体。 另外, 为了提高网元选择实体服务的 可靠性, 网元选择实体中可以包括多个 MMNE, 从而形成 MMNE池(MMNE POOL )0 另外, 当网元选择实体中包括多个 MMNE时, 也可以为各个 MMNE 分配优先级。 此时, 当 UE与服务基站设备建立 RRC连接时 UE未通知服务基 站设备其已经注册的 MMNE的标识时, 服务基站设备根据该网元选择实体中 各个 MMNE的优先级连接到某一个 MMNE, 从而使该 MMNE作为为 UE分 例如, 可以为各个 MMNE分配权重, 权重越高的优先级越高; 还可以根据各 个 MMNE的负载情况确定优先级, 负载越少的优先级越高, 等等。 另外, 由于网元选择实体至少包括一个 MMNE, 因此, 网元选择实体可 以为部署于现网中的至少一个 MMNE上的实体, 或者为现网中新部署的专门 用于执行本发明实施例提供的网元选择实体的功能的包括至少一个 MMNE的 实体。 另外, 结合网络包括的网络类型, 如果网络是由传统网络和虚拟化网络 共同组成的, 例如, 由 EPC和 vEPC共同组成的, 则网元选择实体还可以为提 供虚拟 MMNE服务的设备。 当然, 网元选择实体还可以为管理 MMNE或者 MMNE池的设备, 等等。 另夕卜, 由于网元选择实体为与 MMNE相关的设备, 因此,网元选择实体可以与某一 MMNE—体,也可以独立于各个 MMNE之外, 本发明实施例对此不作具体限定。 其中, 关于网元选择实体的具体形态, 本发 明实施例不作具体限定。 具体实施时, 网元选择实体可以是嵌入式的, 也可以 是云网络的, 等等。
另外, 关于网元选择实体与服务基站设备之间的接口协议, 本发明实施例 不作具体限定。 具体实施时, 保证该接口协议为用于接入网设备和核心网中用 于移动性关联的设备之间的接口协议即可。 例如, 可以为 S1接口协议, Gb接 口协议, Iu接口协议, 等等。 其中, S1接口是 LTE系统中演进无线接入网与 演进核心网之间的接口; Gb接口是 SGSN和 BSS ( Base Station Subsystemgsm, 基站子系统)之间接口; Iu接口负责核心网和 RNC之间的信令交互。
关于服务基站设备选择网元选择实体作为 UE的第一服务 MMNE的方式, 本发明实施例不作具体限定。 具体实施时, 如果网络中包括多个 MMNE, 且 其中某一个 MME充当网元选择实体的角色, 则可以由 EMS预先配置网络时, 将充当网元选择实体的角色的 MME的权重配置为 100%,而其它 MMNE的权 重均配置为 0%。 因此, 如果 UE与服务基站设备建立 RRC连接时 UE未通知 服务基站设备其已经注册的 MME的标识, 由于网元选择实体的权重被配置为 了 100%, 因此, 服务基站设备自动连接到网元选择实体, 将网元选择实体作 为第一服务 MMNE。当然,也可以由 EMS控制当 UE与服务基站设备建立 RRC 连接时 UE未通知服务基站设备其已经注册的 MMNE的标识时, 釆用其它方 法使服务基站设备选择网元选择实体作为第一服务 MMNE, 本发明实施例对 此不作具体限定。
进一步地, 为了触发网元选择实体为 UE选择第二服务 MMNE,服务基站 设备选择网元选择实体作为 UE的第一服务 MMNE后, 可以通过向网元选择 实体发送初始用户消息来触发为 UE选择第二服务 MMNE的过程。 关于服务 基站设备向网元选择实体发送初始用户消息的方式, 本发明实施例不作具体限 定。
403: 网元选择实体在 UE注册流程中获取 UE的用户信息。
为了为 UE分配第二服务 MMNE, 网元选择实体需要在 UE注册流程中获 取 UE的用户信息,以确保后续可以根据用户信息为 UE选择第二服务 MMNE。 其中, 由于本发明实施例针对新接入网的用户, 因此, 该注册流程对应附着流 程。
其中, 关于用户信息的具体内容, 本发明实施例不作具体限定。 具体实施 时, 用户信息包括但不限于为 IMSI信息、 TAI信息、 APN信息, 以及签约信 息中的至少一种信息。
关于网元选择实体在 UE注册流程中获取 UE的用户信息的方式, 包括但 不限于:网元选择实体在 UE注册流程中从 UE或者 HSS获取 UE的用户信息。 具体地, 由于新接入网络的 UE通过附着流程与 MMNE建立连接, 因此, 网 元选择实体可以从附着流程中获取 UE的用户信息。 例如, 当服务基站设备通 过向网元选择实体发送初始用户消息触发网元选择实体选择第二服务 MMNE 的过程时, 由于初始用户消息中包括附着请求, 且附着请求中通常包括 IMSI、 APN等用户信息。 因此, 网元选择实体可以通过接收初始用户消息, 并通过解 析初始用户消息获取 UE的用户信息。另夕卜, 由于 UE与 MMNE建立连接进行 的附着流程中, 通常会包括附着承载的过程, 且在附着承载过程中, HSS会返 回签信息, 因此, 网元选择实体可以通过接收 HSS返回的签约信息获取 UE的 用户信息。 当然, 网元选择实体还可以釆用其它方式在 UE注册流程中获取 UE 的用户信息, 本发明实施例对此不作具体限定。
404: 网元选择实体根据用户信息和至少一个候选服务 MMNE的对应关系 确定为 UE选择的第二月良务 MMNEo
其中, 网元选择实体预先存储有用户信息和至少一个候选服务 MMNE的 对应关系, 且预先存储的用户信息和至少一个候选服务 MMNE的对应关系为 运营商根据控制网络的需求灵活设置的根据 UE 的用户信息为 UE 分配服务 MMNE的具体内容。 其中, 预先存储的用户信息和至少一个候选服务 MMNE 的对应关系可以存储在网元选择实体本地, 也可以存储在云端, 本发明实施例 对此不作具体限定。
由于运营商可以根据控制网络的需求灵活设置用户信息和至少一个候选 服务 MMNE的对应关系, 在此种情况下, 可以根据控制网络的需求将用户信 息为某一类型的 UE与某些或某个 MMNE对应起来。 由于可以根据需要任意 设置用户信息与候选服务 MMNE的对应关系,使得可以将具有一定特征的 UE 接入某个具体的 MMNE, 不仅便于控制选择 MMNE的过程, 而且也可以预先 分配某些 MMNE处理特定业务, 从而使得在根据用户信息确定某些 UE需要 处理特定业务时可以直接控制该 UE选择到该能够处理特定业务的 MMNE上, 确保为 UE选择良务 MMNE的方式更加灵活。
例如, 如果网络仅包括 EPC, 则可以将用户信息为某一类型的 UE与能够 处理特定业务的候选服务 MMNE对应。
又例如, 如果 LTE系统是由 EPC和 vEPC共同组成的网络, 且运营商想 控制分配传统运营商的用户选择到 EPC, 而虚拟运营商的用户选择到 vEPC, 则可以在设置用户信息和至少一个候选服务 MMNE的对应关系时, 使 EPC包 括的 MMNE对应传统运营商的用户的用户信息, 使 vEPC包括的 MME对应 虚拟运营商的用户的用户信息。 因此,在传统运营商的用户的 UE接入网络时, 由于传统运营商的用户的 UE的用户信息与 EPC包括的 MMNE对应, 因此, 可以自动接入到 EPC包括的某一 MMNE。 关于网元选择实体根据用户信息和至少一个候选服务 MMNE的对应关系 确定为 UE选择的第二服务 MME的方式, 本发明实施例不作具体限定。 具体 实施时, 由于用户信息可以包括^^丰富的内容, 因此, 网元选择实体可以通过 将用户信息包括的具体内容与网元选择实体根据用户信息和至少一个候选服 务 MMNE的对应关系中的用户信息进行最大匹配来实现。 另外, 针对于网元 选择实体包括多个 MMNE的情况, 由于还可以为每个 MMNE设置优先级, 因 此, 网元选择实体根据用户信息和至少一个候选服务 MMNE的对应关系确定 为 UE选择的第二服务 MMNE包括但不限于: 网元选择实体根据用户信息和 多个候选服务 MMNE的对应关系以及多个候选服务 MMNE的优先级从多个候 选服务 MMNE中确定第二服务 MMNE。 其中, 本发明实施例不对限定优先级 的具体形式进行限定。 具体实施时, 优先级包括但不限于预先设置的各个候选 服务 MMNE的权重或者各个 MMNE的负载情况, 等等。
另外, 由于用户信息可以更包含艮多内容, 因此, 用户信息和至少一个候 选服务 MMNE的对应关系中预先设置的用户信息与候选服务 MMNE的对应关 系也可以包含艮丰富的内容。 例如, 对于 EPC和 vEPC共同存在的网络, 预先 设置的用户信息与候选服务 MMNE的对应关系可以包括用户信息与网络类型 之间的对应关系。 例如, 预先设置某些候选服务 MMNE与 EPC对应; 预先设 置某些候选服务 MMNE与 vEPC对应。 因此, 根据用户信息和至少一个候选 服务 MMNE的对应关系确定为 UE选择的第二服务 MMNE, 包括但不限于: 根据用户信息确定 UE所属网络类型, 并在该网络类型包括的 MMNE中选择 UE的第二服务 MMNEo
具体地, 如果用户信息对应的网络类型为 EPC, 则第二服务 MMNE为传 统运营商的 MMNE, 因此, 在传统运营商的 MMNE 中选择 UE的第二服务 MMNE;如果用户信息对应的网络为 vEPC,则第二服务 MMNE为虚拟运营商 的 MMNE, 因此, 在虚拟运营商的 MMNE中选择 UE的第二服务 MMNE。 例 如, 如果确定用户信息对应的网络类型为 vEPC, 则在 vEPC包括的所有 MME 中选择 UE的第二服务 MMNE, 且第二服务 MMNE为虚拟运营商的 MMNE。 为了便于对上述网元选择实体根据用户信息网元选择实体根据用户信息 和至少一个候选服务 MMNE的对应关系确定为 UE选择的第二服务 MMNE的 过程进行解释说明, 下面以用户信息为 IMSI时网元选择实体根据用户信息和 至少一个候选服务 MMNE的对应关系确定为 UE选择的第二服务 MMNE的过 程进行举例说明。
由于 IMSI=MCC+MNC+ABCD+XXXXXX, 其中, MCC+MNC+ABCD可 以设置为 IMSI的前缀。 如表一所示, 其示出了一种用户信息和至少一个候选 服务 MMNE 的对应关系中包括的 IMSI 前缀与该前缀的 IMSI对应的候选 MMNE的关系。
Figure imgf000024_0001
Figure imgf000024_0003
由于在表一所示的用户信息和至少一个候选服务 MMNE的对应关系中, 前缀为 MCC+MNC+ABCD对应的候选服务 MMNE有 MMNE3和 MMNE4, 又由于预先设置的 MMNE3 的权重为 40%, MMNE4 的权重为 60%, 可见 MMNE3的优先级比 MMNE4的高。 因此, 选择 MMNE4作为 UE的第二服务 MMNE。
又例如, 如果用户信息为 TAI, 且用户信息和至少一个候选服务 MMNE 的对应关系中设置的 TAI与候选服务 MMNE的对应关系如表二所示:
Figure imgf000024_0002
Figure imgf000024_0004
由表二可得, 当 UE的 TAI表明用户为北京的用户时, 根据用户信息和至 少一个候选服务 MMNE的对应关系, 将 MMNE1 作为服务 UE 的第二服务 MMNE。
还例如, 如果用户信息为 APN, 且用户信息和至少一个候选服务 MMNE 的对应关系中设置的 APN与候选服务 MMNE的对应关系如表三所示:
Figure imgf000025_0001
Figure imgf000025_0002
由表三可得, 当 UE的 APN表明用户为语音业务用户时, 根据用户信息 和至少一个候选服务 MMNE的对应关系, 将 MMNE5作为服务 UE的第二服 务 MMNE。
当然, 上述举例分别以用户信息为 IMSI、 TAI和 APN为例进行了说明。 然而, 在具体实施时, 也可以将用户信息包括的各种具体内容进行组合来为 UE分配第二服务 MMNE。 例如, 如果用户信息中同时包括了 IMSI和 APN, 则网元选择实体需要根据 IMSI和 APN的组合来为 UE分配第二服务 MMNEo 关于根据用户信息包括的各种信息的组合分配第二服务 MMNE的方式, 此处 不再举例说明。
另外, 由于用户信息还包括 HSS返回的签约信息, 因此,也可以根据 HSS 返回的签约信息和至少一个候选服务 MMNE的对应关系得到用户信息对应的 MMNE, 从而将用户信息对应的 MMNE作为第二服务 MMNE。 其中, 根据 HSS返回的签约信息确定第二服务 MMNE的方式同上述根据 IMSI、 TAI或 APN确定第二服务 MMNE的方式类似, 此处不再举例说明。
405: 网元选择实体向 UE分配属于第二服务 MMNE的一个 GUTI, 并通 过服务基站设备向 UE返回携带 GUTI的附着接受消息。
当网元选择实体为 UE确定第二服务 MMNE后,为了后续 UE可以附着到 该第二服务 MMNE 上, 网元网元选择实体需要通知 UE 为其分配了哪个 MMNE。 由于 GUTI = GUMMEI + M-TMSI, 其中, GUMMEI即为全球唯一 MMNE标识, 因此, 根据 GUTI可以唯一识别 MMNE。 为了使 UE可以识别 网元选择实体为其分配了哪个 MMNE, 网元选择实体为 UE 分配第二服务 MMNE的一个 GUTI, 并通过将 GUTI携带在附着接受消息中通过服务基站设 备返回给 UE。
关于网元选择实体为 UE分配属于第二服务 MMNE的一个 GUTI的方式, 本发明实施例不作具体限定。 具体实施时, 可以从第二服务 MMNE所对应的 号段中随机选择一个 GUTI; 也可以预先为每个 MME对应的 GUTI号段进行 排序, 因此, 在分配第二服务 MMNE的一个 GUTI时, 可以按 UE接入的顺 序选择一个 GUTI, 等等。
需要说明的是, 用户信息和至少一个候选服务 MMNE的对应关系中同时 也存储了各个 MMNE对应的可分配的 GUTI号段。 因此, 在为 UE分配属于 第二服务 MMNE的一个 GUTI时, 也可以从对应的可分配的 GUTI号段中选 择一个 GUTL如表四所示,其示出了一种用户信息和至少一个候选服务 MMNE 的对应关系中存储的各个 MMNE及其对应的可分配 GUTI号段的表格。
表四
Figure imgf000026_0001
另外, 关于通过服务基站设备向 UE返回携带 GUTI的附着接受消息的方 式, 本发明实施例不作具体限定。 具体实施时, 可以通过服务基站设备的通道 将携带 GUTI的附着接受消息返回给 UE。 其中, 该附着接受消息可以对应协 议 3GPP TS 23.401的 5.3.2.1的第 17号消息。
406: UE接收携带 GUTI的附着接受消息。
关于 UE接收携带 GUTI的附着接受消息的方式, 本发明实施例不作具体 限定。 通过上述步骤即为 UE 分配了一个可以与其用户信息对应的第二服务 MMNE。 然而, 在具体实施时, 为了使分配的第二服务 MMNE顺利为 UE服 务, 还需要确保 UE与该第二服务 MMNE建立连接, 即 UE附着在第二服务 MMNE上。 因此, 还需要执行下面的步骤。
407: 网元选择实体向 UE发送用于指示进行隐式分离的分离消息, 其中, 分离消息包括指示发起重新附着流程的指示信息。
其中,该步骤为网元选择实体指示 UE重新发起附着流程的具体实现方法。 通常, UE通过重新附着流程与 MMNE建立连接, 为了使 UE附着到第二服务 MMNE上, 网元选择实体可以向 UE发送用于指示进行隐式分离的分离消息, 从而在分离消息中指示 UE发起重新附着流程。
其中, 关于网元选择实体向 UE发送用于指示进行隐式分离的分离消息的 方式, 可以有艮多种。 具体实施时, 可以在步骤 406后立即通过向 UE发送用 于指示进行隐式分离的分离消息指示 UE发起重新附着流程, 也可以间隔一段 时间后再向 UE发送用于指示进行隐式分离的分离消息指示 UE发起重新附着 流程。 然而, 为了使 UE顺利与第二服务 MMNE连接, 可以立即发送该分离 消息。
另外, 在分离消息中携带重新附着流程的指示信息方式, 可以有很多种。 具体实施时, 包括但不限于通过将分离消息中的附着类型设置为重新附着来实 现。 其中, 关于隐式分离流程的具体内容, 可以参考协议 3GPP TS 23.401的 5.3.8.3的具体内容。
408: UE接收分离消息, 并根据分离消息向服务基站设备发送携带 GUTI 的重新附着请求消息。
该步骤为 UE附着到第二服务 MMNE的具体实现方法。 UE接收分离消息 后, 由于该分离消息中携带了重新附着指示。 因此, UE根据重新附着指示向 服务基站设备发送携带 GUTI的重新附着请求消息来触发重新附着流程, 从而 触发附着到第二服务 MMNE。 关于 UE接收分离消息的方式, 以及根据分离消 息向服务基站设备发送携带 GUTI的重新附着请求消息的方式, 本发明实施例 不作具体限定。
409: 服务基站设备接收重新附着请求消息, 并将 GUTI对应的 MMNE作 为服务 UE的第二服务 MMNEo
由于 GUTI = GUMMEI + M-TMSI,而 GUMMEI为全球唯一 MMNE标识, 因此, 服务基站设备接收重新附着请求消息后, 将 GUTI对应的 MMNE作为 UE的第二服务 MMNEo
本发明实施例提供的方法, 通过 UE的用户信息与候选服务 MMNE的对 应关系为 UE选择服务 MMNE, 能够实现为具备某一特征的 UE选择特定的 MMNE, 较现有技术提高了 MMNE选择的灵活性。针对新入网的 UE, 可以在 该 UE接入网络后就将该 UE分配至预先设置的与其用户信息对应的 MMNE 不仅方便了运营商网络管理, 而且能简单高效为该 UE选择服务 MMNE。 图 5是根据一示例性实施例示出的一种用户设备注册的方法的流程图。在 该实施例中, 以网元选择实体发起迁移至少一个已经注册在第三服务 MMNE 上的 UE, 并为该至少一个已经注册在第三服务 MMNE上的 UE重新选择一个 第二服务 MMNE为例对本发明实施例提供的方法进行详细地解释说明。 参见 图 5, 本发明实施例提供的方法流程包括:
501 :网元选择实体向 EMS发送迁移至少一个已经注册在第三服务 MMNE 上的 UE的迁移指令。
其中, 该步骤至下述步骤 505 为网元选择实体通过 EMS 指示第三服务 MMNE对已经注册在第三服务 MMNE上的至少一个 UE发起用于迁移该至少 一个 UE的流程的具体实现方法。 需要说明的是, 此处, 至少一个需要被迁移 的 UE已经注册的 MMNE可以为同一个 MMNE, 也可以不同的 MMNE。 为了 便于说明, 在该实施例中, 以至少一个需要被迁移的 UE均已经注册在第三服 务 MMNE上为例进行说明。 结合图 1所示的网络架构示意图和上述实施例的具体内容, 当引入网元选 择实体后, 由于网元选择实体可以根据预先设置的用户信息和至少一个候选服 务 MMNE的对应关系为 UE选择第二服务 MMNE。 因此, 当需要迁移一个或 一些已经注册在第三服务 MMNE上的 UE时, 网元选择实体可以发起迁移已 经注册在第三服务 MMNE上的 UE的 MMNE迁移过程, 亦即改变为这些已经 注册在第三服务 MMNE上的 UE服务的 MMNE, 从而为该至少一个已经注册 在第三服务 MMNE上的 UE重新选择第二服务 MMNE。 其中, 为了触发发起 MMNE迁移过程, 网元选择实体包括但不限于通过向 EMS发送迁移至少一个 已经注册在第三服务 MMNE上的 UE的迁移指令来实现。 关于网元选择实体 向 EMS发送迁移至少一个已经注册在第三服务 MMNE上的 UE的迁移指令的 方式, 本发明实施例不作具体限定。 具体实施时, 网元选择实体可以使用 Northbound-Inf (北向接口 ) 向 EMS 发送迁移至少一个已经注册在第三服务 MMNE上的 UE的迁移指令。 其中, 北向接口是 EMS提供给 NMS的接口。 关于北向接口的具体类型, 本发明实施例不作具体限定。 具体实施时, 北向接 口的具体类型可以有 CORBA ( Common Object Request Broker Architecture , 公 共对象请求代理体系结构)接口、 MML ( Man-Machine Language, 人机语言) 接口、 文件接口等, 具体应由各厂商的 EMS能提供的接口为准。
另夕卜,网元选择实体通过 EMS指示第三服务 MMNE对已经注册在第三服 务 MMNE上的至少一个 UE发起用于迁移该至少一个 UE的流程时,可以逐个 UE迁移一次, 也可以逐批 UE迁移一次, 等等。 当逐个 UE迁移一次时, 每个 迁移指令携带该次迁移的 UE的标识; 当逐批 UE迁移一次时, 每个迁移指令 携带该次迁移的所有 UE的标识。
502: EMS将迁移指令转发至第三服务 MMNE。
为了触发第三服务 MMNE对已经注册在其上的 UE发起用于迁移该 UE 的流程, 并使第三服务 MMNE停止服务已经注册在其上的一个或一些需要迁 移的 UE, 可以执行该步骤。 关于 EMS将迁移指令转发至第三服务 MMNE的 方式, 本发明实施例不作具体限定。
503: 第三服务 MMNE接收迁移指令, 并根据该迁移指令向已经注册在第 三服务 MMNE的 UE发送上下文释放要求消息。
由于在具体的通信过程中, 当 MMNE会发起原因值为 "Load Balancing TAU Required (负载均衡要求;)" 的释放流程, 后续已经在网络驻留的 UE就不 会在 RRC Connection Setup Complete消息 ( RRC连接建立完成消息) 中包含 UE已经注册的 MMNE的标识。 因此, 第三服务 MMNE接收迁移指令, 并根 据该迁移指令向已经注册在第三服务 MMNE的 UE发送上下文释放要求消息, 使得已经注册在第三服务 MMNE上的 UE明确需要改变服务 MMNE。 其中, 该上下文释放要求消息即为上述 Load Balancing TAU Required 0
504: 已经注册在第三服务 MMNE的 UE接收上下文释放要求消息, 并向 服务基站设备发送 TAU请求。
UE接收上下文释放要求消息后, 便获知需要重新选择 MMNE, 此时, 可 以通过向服务基站设备发送 TAU请求触发 TAU过程。
505: 服务基站设备接收 TAU请求, 并将 TAU请求发送给网元选择实体。 由于当第三服务 MMNE发起原因值为 "Load Balancing TAU Required" 的 释放流程后, 后续每个已经在网络驻留的 UE就不会在 RRC Connection Setup Complete消息中包含 registeredMME。 因此,服务基站设备根据 TAU请求重新 为 UE选择服务 MMNE。 关于服务基站设备根据 TAU请求重新为 UE选择服 务 MMNE的方式, 由于本发明实施例中服务基站设备选择网元选择实体作为 UE的第一服务 MMNE, 且网元选择实体可以根据预先存储的用户信息和至少 一个候选服务 MMNE的对应关系为 UE分配 MMNE, 因此, 服务基站设备将 该 TAU请求发送给网元选择实体, 从而触发网元选择实体可以根据预先设置 的用户信息和至少一个候选服务 MMNE 的对应关系为 UE 分配第二服务 MMNE。
506: 网元选择实体接收 TAU请求, 并根据 TAU请求在注册流程中获取 UE的用户信息。
关于网元选择实体接收 TAU请求的方式, 以及根据 TAU请求在注册流程 中获取每个已经在网络驻留的 UE的用户信息的方式, 本发明实施例均不作具 体限定。 具体地, 由于该实施例针对于已经注册在第三服务 MMNE上的 UE, 因此, 注册过程对应 TAU流程。 关于 TAU流程的具体内容以及根据 TAU请 求在注册流程中获取 UE的用户信息的方式, 可以参见相关协议, 本发明实施 例对此不作具体限定。
507: 网元选择实体根据用户信息至少一个候选服务 MMNE的对应关系确 定为 UE选择的第二服务 MMNE。
该步骤的原理同图 4所示实施例中步骤 404的原理一致, 具体可参见图 4 所示实施例中步骤 404的内容, 此处不再赘述。
508: 网元选择实体向 UE分配属于第二服务 MMNE的一个 GUTI, 并通 过服务基站设备向 UE返回携带 GUTI的附着接受消息。
该步骤的原理同图 4所示实施例中步骤 405的原理一致, 具体可参见图 4 所示实施例中步骤 405的内容, 此处不再赘述。
509: UE接收携带 GUTI的附着接受消息。
该步骤的原理同图 4所示实施例中步骤 406的原理一致, 具体可参见图 4 所示实施例中步骤 406的内容, 此处不再赘述。
510: 网元选择实体向 UE发送用于指示进行隐式分离的分离消息, 其中, 分离消息包括指示发起重新附着流程的指示信息。
该步骤的原理同图 4所示实施例中步骤 407的原理一致, 具体可参见图 4 所示实施例中步骤 407的内容, 此处不再赘述。
511 : UE接收分离消息, 并根据分离消息向服务基站设备发送携带 GUTI 的重新附着请求消息。
该步骤的原理同图 4所示实施例中步骤 408的原理一致, 具体可参见图 4 所示实施例中步骤 408的内容, 此处不再赘述。 512: 服务基站设备接收重新附着请求消息, 并将 GUTI对应的 MMNE作 为服务 UE的第二服务 MMNEo
该步骤的原理同图 4所示实施例中步骤 409的原理一致, 具体可参见图 4 所示实施例中步骤 409的内容, 此处不再赘述。
本发明实施例提供的方法, 通过 UE的用户信息与候选服务 MMNE的对 应关系为 UE选择服务 MMNE, 能够实现为已经注册在第三服务 MMN上的 UE重新分配服务 MMNE, 使得已经注册在第三服务 MMNE上的具备一定特 征的 UE可以重新选择到特定的 MMNE, 较现有技术提高了 MMNE选择的灵 活性。 另外。 由于可以通过修改用户信息与候选服务 MMNE的对应关系, 因 此,运营商能够根据不同的策略为 UE选择 MMNE, 方便了运营商进行网络管 理。 需要说明的是: 上述实施例提供的网元选择实体在执行用户设备注册的方 法时, 仅以上述各功能模块的划分进行举例说明, 实际应用中, 可以根据需要 而将上述功能分配由不同的功能模块完成, 即将设备的内部结构划分成不同的 功能模块, 以完成以上描述的全部或者部分功能。 另外, 上述实施例提供的网 元选择实体与用户设备注册的方法实施例属于同一构思, 其具体实现过程详见 方法实施例, 这里不再赘述。
