Description

异系统小区的管理方法、 装置与系统 技术领域 本发明实施例涉及移动通信领域，并且更具体地，涉及一种异系统小 区的管理方法、 装置与系统。 背景技术 异无线接入技术（也称异系统）节能（ Inter-RAT Energy Saving , IRAT ES )是国际标准化组织第三代合作伙伴计划（ The 3rd Generation Partnership Project , 3GPP )在版本十一（ release 11 , Rel-11 )的一个热点标准课题。
由于不同的无线接入技术（ Radio Access Technology , RAT )系统业务 的差异性，异系统节能所面临的一个问题是： 当需要对某小区执行节能关 闭时，该小区内存在这样一种活动（ Active )用户设备（ User Equipment , UE ) ,该 Active UE所承载的业务只有该小区所属的 RAT系统才有能力提 供，如果该小区执行节能关闭 ，则该 Active UE的业务服务质量（ Quality of Service , QoS )将受到影响。
针对以上问题，比较常见的一种处理方式是： 由网络管理设备设置节 能策略 __在以上情况下，禁止启用节能关闭。 但以上情况发生概率较高， 设置这样的策略基本上封杀了异系统节能的应用。 发明内容 本发明实施例提供一种异系统小区的管理方法、 装置及系统，在异系 统小区场景中 ，在保持一定的节能增益的同时，保证了不同类型业务 QoS 在节能过程中不受影响。
本发明实施例的一个方面提供一种异系统小区的管理方法，包括：接 入网设备将第二无线接入技术 RAT 2小区中的不承载特定业务的活动用户 设备切换到第一无线接入技术 RAT 1小区，其中所述特定业务为所述 RAT 2 小区具有承载能力且所述 RAT 1小区不具有承载能力的业务；接入网设备 控制所述 RAT 2小区进入限定节能模式。

随着 RAT的快速发展，当传统的 RAT网络还在提供基础服务时，新的 RAT 网络已需要投入使用。 为了更好地利用已有的网络资源，异无线接入 技术（ inter-RAT )系统功能优先于同无线接入技术（ intra-RAT )系统功能 在网络中实施。
举例而言 2G或 3G制式的小区，例如全球移动通讯系 Global System of Mobile communication , GSM )或通用移动通信系统 ( Universal Mobile Telecommunications System , UMTS )等，提供整个网络区域的基础覆盖， 新的 RAT系统，例如长期演进（ Long Term Evolution , LTE )系统，长期演 进高级（ long term evolution advanced , LTE-A )系统等，提供同一区域内的 热点增容（ capacity enhancement )b 当热点增容的 RAT小区处于具有统计规 律性的低负载周期（ Low Load Period , LLP )时，将 RAT小区中低负载状 态下的 Active UE定向地切换到提供基础覆盖的 2G或 3G制式小区中 RAT 小区进行节能关闭。
然而，以上异系统小区节能面临以下问题： 当需要对某小区执行节能 关闭时，该小区内存在 Active UE ,该 Active UE所承载的业务只有该小区 所属的 RAT系统才有能力提供，如果该小区执行节能关闭 ，则该 Active UE 的服务质量（ Quality of Service , QoS )将受到影响。 例如：
情况一： Active UE为支持多种 RAT制式的多模终端，且其承载了只有 欲进行节能关闭的小区才有能力提供相应数据速率的业务。例如，当 GSM/ UMTS组合组网中 UE发起或进行 384kbps分组业务时，该业务承载只能由 UMTS网络提供。 UMTS/LTE组合组网中 UE发起或进行 10Mbps的视频业 务时，该业务只能由 LTE网络提供。
情况二： Actwe UE为支持一种 RAT制式的单模终端，且欲进行节能关 闭的小区为其所支持的 RAT制式的小区。 例如，单模的 LTE数据卡。
以上两种情况，为了保证 Active UE的业务 QoS不受影响，此时，小 区不能进行节能关闭。
另外，以上异系统小区节能策略还面临空闲（ Idle ) UE 重选的问题。 当大量的 Idle UE驻留在某小区，而该小区又瞬时关闭 ，众多的 Idle UE进 行异系统小区重选而发生位置区更新 ， 对无线接入网 （ Radio Access Network , RAN )和核心网（ Core Network , CN )形成短时的信令风暴。 此 时，小区也不能进行节能关闭。
为此，以下实施例提供了异系统小区的管理方法，在异系统小区场景 中 ，在保持一定的节能增益的同时，保证了不同类型业务 QoS在节能过程 中不受影响。
为了便于描述，对异系统节能场景下两类不同角色的小区进行定义： 第一无线接入技术 RAT 1小区：为能够执行节能策略的小区提供同一 区域的基础覆盖的小区，例如：上述场景中的 2G或 3G小区。
第二无线接入技术 RAT 2小区：能够执行节能策略的小区，例如：上 述场景中的 LTE小区。
请参考图 1 ，其为本发明实施例所提供的一种异系统小区的管理方法的 示范性流程图。 如图 1所示，该方法包括：
S110：接入网设备将第二无线接入技术 RAT 2小区中的不承载特定业 务的活动用户设备切换到第一无线接入技术 RAT 1小区，其中所述特定业 务为所述 RAT 2小区具有承载能力且所述 RAT 1小区不具有承载能力的业 务；
S120：所述接入网设备控制所述 RAT 2小区进入限定节能模式，从而， 将 RAT 2小区激活为限定节能模式。
在面对 RAT 2小区中始终出现的少量特定业务时，以上方法提供了一 种限定节能策略：将不承载特定业务的活动用户设备切换到 RAT 1小区， 这是为了满足 inter-RAT节能的应用需求（区别于 intra-RAT节能的主要特 性） b并且，不同于现有技术将 RAT 2小区完全关闭 ，而是将 RAT 2小区激 活为限定节能模式，即关闭部分资源，以最小的 RAT 2系统资源支持该状 态下 RAT 2特定业务的运行。 从而，在保持一定的节能增益的同时，保证 了不同类型业务 QoS在节能过程中不受影响。
为了使以上特定业务的含义更加易于理解，下面对异系统小区环境下 的不同业务类型进行分类，以使得在 RAT 2小区处于低负载的情况下不同 类型的业务分别在最适合的无线接入系统中承载进行了描述，同时以 RAT 1 是 UMTS , RAT 2是 LTE为例，将一些常见的业务分流 (traffic steering)的策 略列于表 1中。
表 1
Figure imgf000009_0001
在演进分组系统（ Enhanced Packet System , EPS )中 ， QoS类别标识符
( QoS Class Identifier , QCI )是一个数量等级，用来表示控制承载级别的数 据包传输处理的接入点参数，例如调度权重、 接入门限、 队列管理门限、 链路层协议配置等等，并代表了 EPS应该为每个业务数据流（ Service Data Flow , SDF )提供的 QoS特性。 不同 QCI的业务承载可以分为两类：
RAT 2特定业务：指为 RAT 2小区具有承载能力且 RAT 1小区不具有 承载能力的业务，这种承载能力 ，例如可以指足够的 QoS能力。 例如以下 两种业务：第一，如果该业务由 RAT 1小区提供， QoS将发生降级；第二， RAT 1小区的带宽能力根本无法满足该特定业务的业务速率要求。例如：表 1 中的实时游戏业务（ QCI=1 会话型的分组视频业务（ QCI=3 ) ,均属于 RAT 2特定业务，这些业务有较高的业务速率要求，需要 RAT系统提供连 续比特速率的承载能力。
RAT 2和 RAT 1通用业务：指 RAT 1小区或 RAT 2小区都可以提供相 同 QoS能力的业务，用户设备在 RAT I小区和 RAT 2小区对业务的体验没 有显著差别。例如：表 1中的 VOIP业务（ QCI=2 ) ,TCP交互业务（ QCI=7 ) , 均属于 RAT 1和 RAT 2通用业务，这些业务对业务速率的要求不高，即使 由 RAT 1小区提供业务承载， QoS也可以得到保证。 该类业务也称为短时 瞬发的业务（ Bursty Traffic )b
可见，特定业务可以根据服务质量类别标识符 QCI来确定，且 QCI是 一种数量等级，通过 QCI确定特定业务实现简单，且具有更细的粒度。 然 而，本发明实施例不限于此，还可以利用其他任何合适的维度来进行区分， 例如订阅者框架标识符（ Subscriber Profile ID , SPID 业务时延、 业务速 率等。
另外，为了使以上限定节能模式的含义更加易于理解，下面对限定节 能模式进行描述：
限定节能模式是小区低负载状态下的节能模式，在限定节能模式下， 可以仅对承载 RAT 2特定业务的双模 UE和 /或单模的 RAT 2 UE提供业务。
RAT 2小区进入该限定节能模式前，将 RAT 2和 RAT 1通用业务承载迁移 到 RAT 1小区，通过业务分流（ traffic steering )优化 RAT 1小区的容量利 用率，以最小的 RAT 2系统资源支持该模式下 RAT 2特定业务的运行。
表 2归纳了限定节能模式外部可见的特性：
表 2
Figure imgf000011_0001
可见，在限定节能模式下： RAT 2和 RAT 1小区都处于低负载状态； RAT 2特定业务，如：会话分组切换视频业务， 流业务，保留在 RAT 2小区； RAT 2和 RAT 1通用业务，如： VOIP业务、 TCP交互业务，切换到 RAT 1 小区；单模的 RAT 2 UE保持在处于限定的节能态下的 RAT 2小区。 Idle UE 仍然各自分布在 RAT 2或 RAT I小区中不变，不需要做定向的小区重选。 根据本发明实施例 ，通过将不承载特定业务的活动用户设备切换到 RAT 1小区，在 RAT 2小区内仅保留承载特定业务的用户设备，并将所述 RAT 2小区激活为限定节能模式，可以实现如下效果：
a ) RAT 2小区以最小数目的系统资源满足 RAT 2特定业务承载（多模 情况）和 /或单模 RAT 2 UE的业务承载（单模情况）的运行需求；
b )不同类型的业务在 RAT 2小区" 限定节能模式" 下， QoS不发生降 级、 节能效果比" 完全打开的非节能模式" 更有增益；
c )由于 RAT 1小区也处于低负载状态，所以 RAT 2和 RAT 1通用业务 承载被定向切换到 RAT 1小区，从而可以提高 RAT 1小区的容量利用率； d > AT 2小区在限定节能模式下稳定地保证了 RAT 2特定业务的运行， 有效避免了在 RAT 2小区低负载周期内的乒乓效应，所述兵乓效应是指， 因没有活动用户而让 RAT 2小区进入全关闭的节能模式，此后 RAT 2小区 短时突发 RAT 2特定业务请求而被临时打开，在短时业务结束后， RAT 2 小区再次进入全关闭的节能模式；以及
e )空闲用户仍然各自分布在 RAT 2/RAT 1小区中不变，不需要做定向 的小区重选，避免了潜在的因大量的空闲用户同时发起位置区或跟踪区更 新过程而对无线接入网和核心网产生短时的信令风暴。
在以上的描述过程中可以知道，限定节能模式是 RAT 2小区低负载状 态下的节能模式，并不是任何情况下都可以将 RAT 2小区激活为限定节能 模式。 因此以下给出了限定节能模式激活条件。 例如， 当 RAT 2小区的低 负载周期到时，说明 RAT 2小区处于统计周期的低负载状态下。 此时，可 以将 RAT 2小区激活为限定节能模式，相应的， 限定节能模式激活条件包 括 RAT 2小区的低负载周期到时。
其中 ，低负载周期（ Low Load Period , LLP )是由网络管理设备根据一 段历史统计周期采集的性能测量数据形成的以天、 周、 月为单位的固定的、 重复发生的时间周期，在所述的时间周期内所述 RAT 2小区负载（以 RAT 2 为 LTE为例，小区负载指小区物理资源块的占用率）始终低于一预设负载 门限。 例如，按照每天 24 小时 ( 00:00:00-23:59:59 )作为一个小区负载统 计测量周期，划分基站或小区的低负载周期（即非峰值时段），由网络管理 设备，例如，操作、管理和维护 ( Operation, Administration and Maintenance , OAM )系统，根据基站或小区的历史负载统计数据和内部的负载门限进行 判别 ，形成小区低负载周期的起始与结束时间或者低负载周期的起始时间 和持续时长。
判断限定节能模式激活条件是否满足可以在接入网设备处实现，也可 以在网络管理设备处实现，分别描述如下：
在接入网设备处实现： 由于接入网设备可以实时的监控小区的负载状 态，故在接入网设备处可以对限定节能模式激活条件进行扩展，使得 RAT 2 小区在更加有利于进入限定节能模式的情况下，才启用限定节能模式。 例 如，可以实时获取 RAT 1小区和 RAT 2小区的负载，从而在统计的低负载 周期的条件下，进一步判断其实际负载状况是否适合启用限定节能模式。 再如，考虑到特定业务的承载状态，可以进一步判断其实际承载数的状况 (或者对其实际承载数做如以上 RAT 2小区的低负载周期一样的统计，得 到特定业务低承载周期 ，这个更适用于下面将描述的在网络管理设备处实 现判断的过程，包括按照特定业务对应 QCI的小区 E-RAB数性能统计项或 者按照特定业务对应 QCI的小区物理资源块占用率数性能统计项的累加效 果进行特定业务低承载周期的计算）是否适合启用限定节能模式。 因此， 限定节能模式激活条件可以包括以下条件中的一个或多个，其中特定业务 的承载数可以实现为特定业务对应 QCI的当前 E-RAB数或者当前物理资源 块的占用率：
第一、 RAT 2小区的低负载周期到时；
第二、 RAT 2小区的当前负载低于或等于第一负载门限 Th— actl； 第三、 RAT I小区的当前负载低于或等于第二负载门限 Th—act2； 第四、 RAT 2小区的特定业务承载数低于或等于承载数门限 Th— act3。 在网络管理设备处实现：如果网络管理设备实时地监控小区的负载状 态，将需要极大的资源开销。 因此，在目前实际应用中 ，多利用接入网设 备上报的性能测量数据来统计得到低负载周期或特定业务低承载周期 ，特 定业务低承载周期的统计方式同以上低负载周期的描述类似，在此不再赘 述。 此时，限定节能模式激活条件可以包括以下条件中的一个或多个： 第一、 RAT 2小区的低负载周期到时；
第二、 RAT 2小区的特定业务低承载周期到时。
另外，负载是针对小区而言的 ，指小区中有多少可用资源分配给 UE 的业务请求，小区负载越大，可用资源越少；相应地，承载是针对 UE而言 的，当 UE发起业务请求时，网络要为它分配一个承载、即业务的载体资源 , 一个 UE可以同时拥有多个承载，分别运行不同的业务。且以上特定业务的 承载数与小区的负载可以通过网络的性能测量数据来获得，而以上各个门 限 Th— actl、 Th— act2、 Th— act3可以由运营商来根据小区配置或业务流量等 进行设置，本发明实施例不做任何限制。例如，在 LTE系统中 ，每 15分钟 可以获得小区的 E-UTRAN无线接入承载（ EUTRAN Radio Access Bearer , E-RAB )数、 每小时可以获得小区的物理资源块（ Physical Resource Block , PRB )占用率。 因此，以上负载门限和承载数门限可以依据 PRB占用率以 及 E-RAB数来设置。 然而，本发明实施例中不以此为限，本领域技术员可 根据需要在不同的 RAT系统中进行相应的设置，其为本领域技术人员所熟 知在此不再赘述。然而，在一较佳实施例中 ，以上各个门限 Th— actl、Th— act2、 Th_act3的设置可以根据 QCI做不同的设置，从而针对不同业务构建不同的 激活限定节能模式的门限。 此外，将 RAT 2小区激活为限定节能模式之后，还可以包括限定节能 模式的去激活过程。 当然，对于本就处于限定节能模式下的 RAT 2小区， 当不再满足低负载状态下的节能模式运行条件时，还包括对 RAT 2小区的 限定节能模式的去激活过程。
对应于以上限定节能模式激活条件，此处给出限定节能模式去激活条 件，包括 RAT 2小区的低负载周期过时。 相应的 ，当满足限定节能模式去 激活条件时， RAT 2小区可以退出限定节能模式。
同以上限定节能模式激活条件的判断， 限定节能模式去激活条件的判 断可以在接入网设备处实现，也可以在网络管理设备处实现。 分别描述如 下：
在接入网设备处实现： 同以上限定节能模式激活条件的扩展原因 ， 限 定节能模式去激活条件可以包括以下条件中的一个或多个：
第一、 RAT 2小区的低负载周期过时；
第二、 RAT I小区的负载高于负载门限 Th— deactl ；
第三、 RAT 2小区的特定业务承载数高于承载数门限 Th— deact2。
负载门限 Th— deactl与负载门限 Th— act2可以相同 ，也可以不同 ，本发 明实施例不做任何限制。承载数门限 Th— deact2 与承载数门限 Th— act3可以 相同 ，也可以不同 ，本发明实施例亦不做任何限制。 此时，可以不再考虑 RAT 2小区的负载状态是否满足门限要求。 在网络管理设备处实现： 同以上限定节能模式激活条件的扩展原因 ， 限定节能模式去激活条件可以包括以下条件中的一个或多个：
第一、 RAT 2小区的低负载周期过时；
第二、 RAT 2小区的特定业务低承载周期过时。
从以上的描述可以知道， 限定节能模式激活条件与去激活条件的判断 可以在接入网设备进行，也可以在网络管理设备进行，如果在网络管理设 备进行，需要接入网设备将获得的网络的性能测量数据上报给网络管理设 备， 由网络管理设备根据上报的数据进行以上判断，并根据判断结果，发 送激活或去激活指令给接入网设备。 其中 ，所述激活指令用于指示接入网 设备将 RAT 2小区中的不承载特定业务的活动用户设备切换到 RAT 1小区， 且控制 RAT 2小区进入限定节能模式；去激活指令用于指示接入网设备控 制 RAT 2小区退出限定节能模式。
下面描述异系统小区的管理方法在分布式网络架构与集中式网络架构 中的应用。 且在分布式网络架构中 ，以上描述的限定节能模式激活条件或 去激活条件的判断在接入网设备进行；在集中式网络架构中 ，以上描述的 限定节能模式激活条件或去激活条件的判断在网络管理设备进行。
请参考图 2和图 3，其分别示出根据本发明实施例的在分布式网络架构 下异系统小区的管理方法的进入限定节能模式与退出限定节能模式的示范 性信号流图。 该分布式网络架构包括网络管理器 210、 RAT 2 网元管理器 220、 RAT 2网元 230、 RAT 1网元 240和 RAT 1网元管理器 250。在该分布 式网络架构下， RAT 1网元和 RAT 2网元之间可以直接进行通信或者通过 其上级节点（例如网络管理器 210 )进行信息交互，以上限定节能模式激活 条件或去激活条件的判断可以在接入网设备进行，例如可以在 RAT 2网元 230和 /或 RAT 1网元 240 (例如，基站，演进型基站等 RAT 2网元管理 器 220。 网络管理器 210配置限定节能模式策略，该策略具体通过 RAT 2 网元 230执行。
如图 2所示，在分布式网络架构下，关于限定节能模式激活的异系统 小区的管理方法包括如下步骤：
21： RAT 2网元 230判断 RAT 2小区低负载周期是否到时。
22： RAT 2网元 230判断 RAT 2小区的负载与特定业务承载是否满足 条件，即负载是否小于或等于第一负载门限 Th— actl ,特定业务承载数是否 低于或等于承载数门限 Th— act3。
23： RAT 2网元 230通过 RAT I网元 240获取 RAT I小区的负载信息。 该步骤 23可以在步骤 22之后执行，也可以在步骤 21之前执行。 即，可以 RAT 2接入网设备执行本地小区判断之后，需要该负载信息时，再去调用 ； 也可以在开始便调用 ，以便后续使用 ，本发明实施例不做任何限制。
24： RAT 2网元 230判断 RAT 1小区的负载是否满足条件，即负载是 否小于或等于第二负载门限 Th— act2。 以上步骤 23和 24可以替换为 ： RAT 1网元 240判断 RAT 1小区的负 载是否满足条件，即负载是否小于或等于第二负载门限 Th— act2。 若满足条 件，则发送信令通知 RAT 2网元 230其判断结果。 而后 RAT 2网元根据其 判断结果进行以下操作。
25：当以上判断结果均为是时， RAT 2网元 230将 RAT 2小区中的不 承载特定业务的活动用户设备切换到 RAT 1小区，且控制 RAT 2小区进入 限定节能模式。
在执行完步骤 25后， RAT 2小区的状态发生了改变，为了便于网络管 理器 210的管理，可以将该状态改变通知网络管理器 210 (步骤 26 ) ,同时， 也可以将该状态改变通知 RAT 1网元 240 (步骤 27 )b
请继续参考图 3，其与图 2所示的实施例的区别在于，本实施例是关于 限定节能模式去激活的异系统小区的管理方法。 图 3所示实施例是在满足 了其中 RAT 1小区的负载高于负载门限 Th— deactl而 RAT 2小区退出限定 节能模式的情况。 包括如下步骤：
31 ： RAT 1 网元 240 判断 RAT 1 小区的负载是否高于负载门限 Th— deactl。
32：当判断结果为是时，将以上判断结果通知 RAT 2网元 230。
33： RAT 2网元 230控制 RAT 2小区退出限定节能模式。
在执行完步骤 33后， RAT 2小区的状态发生了改变，为了便于网络管 理器 210的管理，可以将该状态改变通知网络管理器 210 (步骤 34 ) ,同时， 也可以将该状态改变通知 RAT 1网元 240 (步骤 35 )b
若是，其它两个条件， RAT 2小区的低负载周期过时或 RAT 2小区的 特定业务承载数高于承载数门限，则判断过程可以在 RAT 2网元 230进行。
请参考图 4和图 5，其分别示出根据本发明实施例的在集中式网络架构 下异系统小区的管理方法的进入限定节能模式与退出限定节能模式的示范 性信号流图。 该集中式网络架构包括网络管理器 410、 RAT 2 网元管理器 420、 RAT 2网元 430和 RAT 1网元 440。 在该集中式网络架构下， RAT 1 网元和 RAT 2网元之间不能直接进行通信，故较佳的，以上限定节能模式 激活条件或去激活条件的判断在网络管理设备进行，例如可以在网络管理 器 410进行。 网络管理器 410配置限定节能模式策略且进行限定节能模式 激活条件或去激活条件的判断，该策略具体通过 RAT 2网元 430执行。
如图 4所示，在集中式网络架构下，关于限定节能模式激活的异系统 小区的管理方法包括如下步骤：
41：网络管理器 410判断 RAT 2小区低负载周期是否到时。
42：当 RAT 2小区低负载周期是否到时时，网络管理器 410向 RAT 2 网元 430发送激活指令。
43： RAT 2网元 430接收激活指令后，将 RAT 2小区中的不承载特定 业务的活动用户设备切换到 RAT 1小区，且控制 RAT 2小区进入限定节能 模式。
在执行完步骤 43后， RAT 2小区的状态发生了改变，为了便于网络管 理器 410的管理，可以将该状态改变通知网络管理器 410 (步骤 44 ) ,同时， 也可以将该状态改变通知 RAT 1网元 440 (步骤 45 )b
请继续参考图 5，其与图 4所示的实施例的区别在于，本实施例是关于 限定节能模式去激活的异系统小区的管理方法。 该方法可以包括：
51：网络管理器 410根据 RAT 2网元 430和 RAT 1网元 440上报的网 络性能测量数据，判断 RAT 2小区的低负载周期是否过时。
52：当 RAT 2小区的低负载周期过时时，网络管理器 410向 RAT 2网 元 430发送去激活指令。
53： RAT 2网元 430接收去激活指令后，控制 RAT 2小区退出限定节 能模式。
在执行完步骤 53后， RAT 2小区的状态发生了改变，为了便于网络管 理器 410的管理，可以将该状态改变通知网络管理器 410 (步骤 54 ) ,同时， 也可以将该状态改变通知 RAT 1网元 440 (步骤 55 )b
请参考图 6，其为本发明实施例所提供的一种异系统小区的管理装置的 示范性框图。 该装置可以位于接入网设备，该管理装置可以包括切换单元 610和控制单元 620。其中切换单元 610用于将 RAT 2小区中的不承载特定 业务的活动用户设备切换到 RAT 1小区；控制单元 620用于控制 RAT 2小 区进入限定节能模式。
关于特定业务和限定节能模式的描述同上，在此不再赘述。
在一实施例中 ，如图 7所示，该装置还包括判断单元 630 ,用于执行如 图 1 所示方法实施例中的限定节能模式激活条件的判断。 且在满足限定节 能模式激活条件时，所述切换单元 610和控制单元 620启动。
当然，以上限定节能模式激活条件的判断也可以不在该装置中进行， 而是在网络管理设备进行， 由网络管理设备判断满足限定节能模式激活条 件后，发出激活指令，指示切换单元 610和控制单元 620启动。 故在其它 实施例中 ，该装置还包括接收单元 640 ,用于接收激活指令。
另外，本发明的实施例还可以提供一种异系统小区的管理装置，包括 判断单元和发送单元，其中判断单元用于判断 RAT 1小区的负载是否高于 负载门限 Th— deactl ,且在判断结果为是时，发送单元用于向 RAT 2网元发 送限定节能模式的去激活指令，以指示 RAT 2网元退出限定节能模式。
本实施例的装置可以用于执行如图 1 所示实施例的方法，其实现原理 和技术效果类似，此处不再赘述。
请参考图 9，其为本发明实施例所提供的一种异系统小区的管理装置的 示范性框图。 该装置可以位于网络管理设备，包括判断单元 910与发送单 元 920，其中所述判断单元 910用于执行如图 1所示方法实施例的限定节能 模式激活条件的判断。 且在满足限定节能模式激活条件时，发送单元 920 , 用于向接入网设备发送激活指令，所述激活指令用于指示接入网设备将
RAT 2小区中的不承载特定业务的活动用户设备切换到 RAT 1小区，且控 制 RAT 2小区进入限定节能模式。
关于特定业务和限定节能模式的描述同上，在此不再赘述。
本实施例的装置可以用于执行如图 1 所示实施例的方法，其实现原理 和技术效果类似，此处不再赘述。
请参考图 10 ,其为本发明实施例所提供的一种异系统小区的管理装置 的示范性框图。 该装置位于网络管理设备，具体包括判断单元 101 与发送 单元 102，其中所述判断单元 101用于执行限定节能模式去激活条件的判断。 且在满足限定节能模式去激活条件时，发送单元 102 ,用于向接入网设备发 送去激活指令，所述去激活指令用于指示所述接入网设备控制所述 RAT 2 小区退出限定节能模式。
关于特定业务和限定节能模式的描述同上，在此不再赘述。
本实施例的装置可以用于执行如图 1 所示实施例的方法，其实现原理 和技术效果类似，此处不再赘述。
参照 ITU-T电信管理网模型，3GPP管理过程的交互角色分为集成参考 点管理器 ( Integration Reference Point Manager , IRPManager )和集成参考 点代理 ( Integration Reference Point Agent , IRPAgent ) , IRPManager的作用 可以相当于网络管理器，负责整个网络的运行、 维护和管理；且 IRPAgent 的作用可以相当于网元管理器，负责对网络中某一类设备的运行、 维护和 管理。 IRPManager 与 IRPAgent 之间的管理接口称为北向接口 ( Interface-Northbound , Itf-N )b
请参考图 11 ,其为本发明实施例给出一种异系统小区的管理系统的示 范性框图。 如图所示，该系统包括 IRPManager 111、 RAT 1基站 112、 RAT 2基站 113以及用户设备 114。其中 RAT 1基站 112与 RAT 2基站 113可以 通过 IRPAgent与 IRPManager进行通信，用户设备 114接入 RAT 2基站的 RAT 2小区，且 RAT 2基站 113包括如图 6、 图 7或图 8所示的异系统小区 的管理装置 115。
在本实施例中 RAT 1基站 112与 RAT 2基站 113分别通过 IRPAgent 116 和 IRPAgent 117与 IRPManager进行通信。 而在其它实施例中 ， RAT 1基站 112与 RAT 2基站 113可以通过同一 IRPAgent与 IRPManager进行通信。且 IRPAgent 可以是独立于基站之外的实体，也可以集成于基站之内。 本发明 实施例不做任何限制。
此时 ， 可以扩展基于无线接入网信息管理 （ RAN Information Management , RIM )的异系统信令过程中 RAT 1小区发起的 RAT 2小区从 节能模式退出到非节能模式过程（类似于 Cell Actwatum )的描述，使之包 含从" 限定节能模式" 退出到" 非节能模式" 的情况。 还可以扩展对节能 状态改变异系统邻区通知的描述，使之包含对" 限定节能模式" 的状态通 知的描述。 此外，可以将激活 RAT 2小区限定节能模式作为一种能力 ，将 RAT 2小区是否打开该能力的标识信息在 RAT 2小区和 RAT 1小区之间交 互。需要说明的是，根据以上图 3，限定节能模式去激活的描述，可以知道， RAT 1小区可以在判断 RAT 1小区的负载高于负载门限 Th— deactl时， 向 RAT 2网元 23发送限定节能模式的去激活指令。那么相应的，本系统的 RAT 1基站 112中也可以包括一种异系统小区的管理装置，用于判断 RAT 1小区 的负载是否高于负载门限 Th— deactl ,且在判断结果为是时，向 RAT 2网元 发送限定节能模式的去激活指令，以指示 RAT 2网元退出限定节能模式。
在另一较佳实施例中 ， IRPManager 111还包括如实施例六所示实施例 的系统小区的管理装置。
较佳的， IRPManager 111中可以设置对异系统节能中 QoS保证和节能 效果权衡的总体策略，该属性可以为枚举类型 {QoS保证优先，节能效果优 先}。 具体，请参考图 12 ,如果设置 QoS保证优先，节能过程执行下图左 侧非节能模式和限定节能模式间的状态迁移；如果设置节能效果优先，节 能过程执行下图右侧非节能模式和节能模式间（现有技术）的状态迁移。
IRPManager还可以向 IRPAgent配置 RAT 2小区进入限定节能模式的时 间表（time schedule ) ,包括时间表的起始和终止的绝对时间 ，或者时间表 的起始时间和持续时长。
此外，还可以将激活或去激活 RAT 2小区的限定节能模式作为 RAT 2 小区所属的接入网设备的一种能力 ， 由 IRPManager向 IRPAgent配置这种 能力 ，允许或禁止打开 RAT 2小区所属接入网设备的该能力。
为了便于以上实施例的实现 ， 可以扩充节能相关的管理属性 ， 由 IRPManager向 IRPAgent配置这些管理属性，例如可以包括以下几种情况： 节能状态属性定义的增强：例如，可以在北向接口 Itf-N的 EUTRAN 网络资源模型中的节能属性（ Energy Saving Properties )对象的节能状态 ( energy Saving State )属性取值中增加" 限定节能模式" ；或者在 energy Saving State属性的取值' 节能模式"（ Energy Saving )中增加一种情况表示 " 限定节能模式"。
节能控制属性定义的增强：例如，可以在北向接口 Itf-N的 EUTRAN 网络资源模型中的 Energy Saving Properties对象的节能控制（ energy Saving Control )属性取值中增加" 进入限定节能模式" 或" 退出限定节能模式" ， 或者在 energy Saving Control属性的取值" 进入节能模式" ( to Be Energy Saving )中增加一种情况表示" 进入限定节能模式" ，或，在 energy Saving Control属性的取值' 退出节能模式"（ to Be Not Energy Saving )中增加一种 情况表示" 退出限定节能模式"。
节能策略属性的增强（针对激活）：例如，可以在北向接口 Itf-N的自 组织网络策略网络资源模型 (； Self Organizing Network Policy Network Resource Model)中的节能策略（ ESPolicies )对象中新增一个属性，表示以 下节能策略： RAT 2小区进入" 限定节能模式" 对特定业务的承载要求，包 括对应的承载数门限 Th— act3和容限时间（特定业务的承载数小于或等于承 载数门限 Th— act3的持续时间）b 以 QCI为特定取值的 E-RAB数为例，参 照表 1 ,当即日寸的 QCI=1 , QCI=3 , QCI=4 , QCI=6 , QCI=8以及 QCI=9的 E-RAB数总和小于承载数门限 Th— act3达到设定的容限时间时， RAT 2小 区进入限定节能模式，预留的资源支撑这些类型 E-RAB的运行。
节能策略的增强（针对去激活）：例如，可以在 ESPol nes对象中新增 —个属性，表示以下节能策略： RAT 2小区退出" 限定节能模式" 对特定业 务的承载要求，包括对应的承载数门限 Th— deact2和容限时间（特定业务的 承载数大于承载数门限 Th— deact2 的持续时间）。 以 QCI 为特定取值的 E-RAB 数为例，当即时的 QCI=1 , QCI=3 , QCI=4 , QCI=6 , QCI=8 以及 QCI=9的 E-RAB数总和大于承载数门限 Th— deact2达到设定的容限时间时， RAT 2小区退出限定节能模式。
本领域普通技术人员可以理解上述实施例的各种方法中的全部或部分 步骤是可以通过硬件模块或硬件模块的组合，处理器和内存等芯片组的组 合，或者程序来指令相关的硬件、 处理器、 芯片组来完成，该程序可以存 储于一计算机可读存储介质中 ，存储介质可以包括：只读内存（ ROM , Read-Only Memory 随机存储器 ( RAM , Random Access Memory 磁盘 或光盘等各种可以存储程序代码的介质。 其它实施例
