Description

一种异构网络小区的配置管理方法、 装置和网管设备 技术领域
本发明涉及通信技术领域, 特别涉及一种异构网络小区的配置管理方法、 装置和网管设备。 背景技术
异构网络(Heterogeneous Network, Hetnet )可以包含不同大小或不同角 色的无线网元。 较为典型的无线网元可以是各种无线制式的宏(macro )基站, 微(micro )基站, 微微 ( ico )基站, 家庭基站(Home NB、 Home eNB ), 无线接入点 (Access Point )等等。 无线制式可以是全球移动通信系统无线接 入网络 ( Global System for Mobile communications EDGE Radio Access Network, GERAN )、 通用移动通信系统 ( Universal Mobile Telecommunications System, UMTS )、 长期演进( Long Term Evolution, LTE )、 演进型的长期演 进( LTE-Advanced, LTE-A )、 无线局域网 (Wireless Local Area Network, WLAN )等等。 在本申请文件中除宏基站的小区 ( Macro cell , 即宏小区) 以 外的其他无线网元的小区统称为小小区 ( small cell )。
除此之外, 采用射频拉远技术还可以在一个宏小区的覆盖范围内, 利用多 个远端射频单元( Radio Remote Unit, RRU )生成多个小小区。 如图 1所示的 异构网络场景, 包含一个宏基站和多个远端无线接点 ( Remote Radio Header, RRH ), 远端无线接点与宏基站之间采用光纤连接进行通信。 其中六边形区域 为宏小区的覆盖范围,宏基站位于其中部位置, 圓形区域则是各小小区的覆盖 范围,各圓形区域内包含一个远端无线接点。 小小区可以具有不同的小区标识 符 (Cell ID ), 也可以具有相同的小区标识符。
由于众多 small cell的加入, 在无线网络中待管理的无线网元数量急剧增 多, 目前网管系统对于宏基站采用的是单一制的网络管理思路, 该方案对每个 小区进行单独的管理。 然而, 小区数量的急剧增多将会导致过多的且不必要的 网络配置管理, 这样会导致网管系统对小区的管理效率降低。 发明内容

为了使本发明的目的、技术方案和优点更加清楚, 下面将结合附图对本发 明作进一步地详细描述, 显然, 所描述的实施例仅仅是本发明一部份实施例, 而不是全部的实施例。基于本发明中的实施例, 本领域普通技术人员在没有做 出创造性劳动前提下所获得的所有其它实施例 , 都属于本发明保护的范围。 本发明实施例提供了一种异构网络小区的配置管理方法,该方法可以在网 管设备中实现, 若有其他网络设备具有对小区进行管理的需求,也可以采用本 如图 2A所示, 包括:
101 : 确定第一小区和上述第一小区所在的小区组;
第一小区可以属于一个小区组( Group ), 小区组内的基站类型可以是任意 的, 即可以是宏基站、 微基站、 微微基站、 家庭基站、 无线接入点等基站类型 中的一种或者一种以上。 一个小区组(Group ) 内的小区数目一般在两个或者 两个以上。小区所属的小区组的依据可以是出于业务需求也可以是出于管理需 求, 本发明实施例对此不予限定, 若上述小区组内有第二小区, 那么第一小区 和第二小区的关系可以更具体地如下:上述第二小区为上述第一小区覆盖范围 内的同频小区, 或者, 上述第二小区为上述第一小区覆盖范围内的异频小区, 或者, 上述第一小区是第二小区的邻区。
102: 为上述第一小区分配用于指示上述第一小区所在小区组的信息, 和 上述小区组内用于指示上述第一小区的信息。
以上实施例,通过指示上述第一小区所在小区组的信息、用于指示上述第 一小区的信息实现以小区组的方式对小区进行管理,避免了对每个小区进行单 独管理,从而为减少网管设备与异构网小区的交互、方便小区关系的管理等提 供了方便和可能, 从而可以提升网管系统的对小区的管理效率。
上述步骤 102中, 用于指示上述第一小区所在小区组的信息可以采用分组 标识来实现, 小区组内用于指示上述第一小区的信息可以采用识别标识来实 现; 可以理解的是小区组内各小区对应的识别标识均不同。后续实施例中将以 采用分组标识和识别标识为例进行举例说明。
进一步地,本发明实施例还提供了为第一小区分配用于指示上述第一小区 所在小区组的信息的如下可选实现方式:
若上述小区组包括第二小区,并且上述第二小区在上述第一小区覆盖范围 内; 上述 102中, 为第一小区分配用于指示上述第一小区所在小区组的信息包 括:将上述小区组内用于指示上述第一小区的信息作为上述用于指示上述第一 小区所在小区组的信息, 或者, 将不同于上述小区组内用于指示上述第一小区 的信息作为上述用于指示上述第一小区所在小区组的信息。
若上述小区组包括第二小区,并且上述第二小区为上述第一小区覆盖范围 内的同频小区, 上述方法还包括: 确定上述第一小区和上述第二小区是否共享 小区标识; 若上述第一小区和上述第二小区共享小区标识, 上述为第一小区分 配小区组内指示上述第一小区的信息包括:为上述第一小区分配上述小区组内 用于指示上述第一小区的第一标识,为上述第二小区分配上述小区组内用于指 示上述第二小区的第二标识, 上述第一标识与上述第二标识不同, 并且上述第 一标识或上述第二标识还用于表示上述第二小区为上述第一小区覆盖范围内 的同频小区。
若上述小区组包括第二小区,并且上述第二小区为上述第一小区覆盖范围 内的同频小区, 上述方法还包括: 确定上述第一小区和上述第二小区是否共享 小区标识; 若上述第一小区和上述第二小区不共享小区标识, 上述为第一小区 分配小区组内指示上述第一小区的信息包括:将上述第一小区当前的小区标识 作为上述小区组内用于指示上述第一小区的信息。
为了方便小区组之间的管理, 上述方法还包括: 为上述第一小区所在小区 组配置用于指示与上述小区组相邻的小区组的信息。
以下实施例将以批量配置小区的配置信息为例进行说明,假定小区分组内 包含两个小区: 第一小区和第二小区, 并且用于指示上述第一小区所在小区组 的信息可以采用分组标识来实现,小区组内用于指示上述第一小区的信息可以 采用识别标识来实现; 请参阅图 2B, 具体如下:
201 : 获取小区分组信息, 上述小区分组信息指定了小区组内包含第一小 区和第二小区;
上述步骤 201中, 第一小区和第二小区属于一个小区组(Group ), 小区组 内的基站类型可以是任意的, 即可以是宏基站、微基站、微微基站、 家庭基站、 无线接入点等基站类型中的一种或者一种以上。 一个小区组(Group ) 内的小 区数目应该在两个或者两个以上。分组可以是出于业务需求也可以是出于管理 需求而进行分组, 本发明实施例对此不予限定, 更具体地: 上述第二小区为上 述第一小区覆盖范围内的同频小区, 或者, 上述第二小区为上述第一小区覆盖 范围内的异频小区, 或者, 上述第一小区是第二小区的邻区。
第二小区为上述第一小区覆盖范围内的同频小区的场景, 可以是图 1所示 的网络场景中的小小基站和宏基站。上述第二小区为上述第一小区覆盖范围内 的异频小区的场景, 可以是两个异频同覆盖的宏基站或者小小基站和宏基站。 在后续实施例中将给出相应的举例说明。
202: 为上述小区组分配分组标识, 为上述第一' 区和第二小区分别分配 在上述小区组内的识别标识;
分组标识可以用于区分不同的小区组,为小区组内的小区分配的识别标识 则可以用于区分组内不同的小区。上述识别标识可以将第一小区、第二小区各 自已有的小区标识作为识别标识来分配,也可以分配新的识别标识,对此本发 明实施例不予限定。
本发明实施例给出了具体如何分配分组标识或识别标识的几个举例, 如 下:
一、若第二小区在上述第一小区覆盖范围内, 上述为上述小区组分配分组 标识包括: 将上述第一小区的识别标识作为分组标识, 或者, 为上述小区组分 配区别于所有小区组内的识别标识的分组标识。
二、 若上述第二小区为上述第一小区覆盖范围内的同频小区还包括: 确定上述第一小区和第二小区是否共享小区标识;
若上述第一小区和第二小区共享小区标识,上述为上述第一小区和第二小 区分别分配在上述小区组内的识别标识包括:
为上述第一小区分配第一标识, 为上述第二小区分配第二标识, 上述第一 标识和第二标识均为上述小区组内的识别标识,且第二标识表示为上述第一标 识的子标识, 用于表示上述第二小区为上述第一小区覆盖范围内的同频小区。 子标识的表现形式可以是:第二标识的字段在第一小区标识的基础上增加若干 字段, 采用这种表现形式来体现第一小区和第二小区之间存在的覆盖关系。
三、若上述第一小区和第二小区不共享小区标识, 上述为上述第一小区和 第二小区分别分配在上述小区组内的识别标识包括:
将上述第一小区和第二小区当前的小区标识作为上述小区组内的识别标 识分配给上述第一小区和第二小区。 203: 为上述第一小区和第二小区配置上述分组标识以及小区组内的识别 标识。
通过为小区分配分组标识、小区组内识别标识实现以小区组的方式对小区 进行管理,避免了对每个小区进行单独管理,从而为减少网管设备与异构网小 区的交互、方便小区关系的管理等提供了方便和可能,从而可以提升网管系统 的对小区的管理效率。 管理以后的使用举例, 具体地: 在上述第一小区和第二小区的配置信息中配置 上述分组标识以及小区组内的识别标识之后还包括:从具有相同分组标识的小 区中选择小区。选择小区的方法可以是任意的预定规则, 例如依据具体需要执 行的操作确定的抽样算法, 具体如何规定本发明实施例不予限定, 以下给出几 种选择小区以后可能执行的操作的应用场景进行举例说明:
例如: 执行对配置管理的对象资源查看操作时, 对具有相同分组标识的小 区可以进行抽样, 查看抽样的小区的资源; 无需查看该分组内的所有的小区的 配置数据, 从而起到简化网管操作, 减少网管负担的效果。 又例如: 在进行网 管性能测量任务的管理中,可以从具有相同分组标识的小区中抽样选择部分小 区,对抽样得到的小区进行性能测量设置, 而无需对该分组内的所有的小区都 进行性能测量任务配置,从而起到简化网管性能管理操作, 减少网管性能管理 数据的效果。
进一步地, 为了方便小区组之间的管理, 上述方法还包括: 若上述小区分 组信息指定的小区组与其它小区组之间存在相邻关系,则配置邻组关系表标识 该小区组与其它小区组之间的相邻关系。
对 Hetnet的管理, 首先是小区的管理, 根据组网方式的不同可以采用不同 的管理方案, 作为一个举例, 参见下图 3。
如图 3所示, 对于 Hetnet小区的管理, 需要对小区进行分组( Cloud Group ) 汇聚, 该部分需要实现小区分组的管理以及组内小区间关系的配置管理。 云组 1 ( Cloud 1 ) 区域是一个出于业务需要而划分的逻辑分组区域(Group ), 彼此 强相关的异构网网元小区( Macro 1 , Small cell 1 , Small cell 2 )都被规划入了 逻辑分组区域 Cloud 1 ,其中, 同频小区 Small cell 1和 Small cell 2都位于 Macro 1 的覆盖范围内, 异频小区 Macro 2也位于 Macro 1的覆盖范围内。 Macro 1和 ^^(^0 2载频分别为?1和?2。 4叚如, 将 Cloud 1区域的区域作为一个小区组, 各 个小区有各自的小区标识( IDentity , ID )。在图 3中 Macro2、 Macro 3以及 Macro 3内的 Small cell 3均未被划入 Cloud 1。
进行小区分组的管理过程中, 可以给每个 Group分配一个分组标识( group
ID ), 那么同一 Group内的小区具有相同的 group ID。 例如, macro 1和 small cell
1、 small cell 2配置属性里都各自含有一个 group ID = 5的值, 则说明这几个小 区同属于标识为 5的 Group。 也可以不专门配置为 group ID, 例如: 宏小区和宏 小区内的小小区, 可以直接采用宏小区的小区标识作为 group ID。 当然, 对于 不采用逻辑分组管理的小区 (也即是说不属于任何小区组的小区), 可以没有 group ID配置属性, 也可以使用一个特殊取值来配置属性 group ID, 比如 0, 表 示该小区不属于任何 Group。
对于可能包含多个 Macro小区的 Cloud Group, 还需要有 Macro cell之间小 区关系的管理, 如下图 4所示, Cloud 1区域是一个出于业务需要而划分的逻辑 区域, 彼此强相关的异构网网元小区都被规划入同一个逻辑区域 Cloud 1 ,
Cloud 1内的所有相关小区包括小区 Macro 1 , Macro 2, small cell 1 , small cell
2, 图 4中 Macro 3以及 Macro 3内的 Small cell 3均未被划入 Cloud 1。 其中, 同频 小区 Small cell 1和 Small cell 2都位于 Macro 1的覆盖范围内, 异频小区 Macro 2 也位于 Macro 1的覆盖范围内。 Macro 1和 Macro 2载频分别为 F1和 F2。 因此, 对于 Macro 1 和 Macro 2之间也需要进行管理。 类似实施例 1中的方法, 对于 Macro 1和 Macro 2小区的配置属性, 可以新增一个标识分组编号信息的 groupIDo
Hetnet网络中邻区关系表 ( Neighbour Relation Table, NRT ) 的属性, 也需 要做相应的变化。 在本发明实施例中的 NRT表中, 表示一个邻区关系时, 不仅 仅有小区 ID, 可选的, 还需要增加各自小区的分组标识(group ID )。
对每个 Group内的小区配置好 group ID之后, 可以在后续的网管配置操作 里, 进行有针对性的优化操作。 例如, 执行配置管理的对象资源查看操作时, 对具有相同 group ID的小区可以进行抽样查看而无需查看该分组内的所有的 小区配置数据, 从而起到简化网管操作, 减少网管负担的效果。 又例如, 在进 行网管性能测量任务的管理中, 可以从具有相同 group ID的小区中抽样选择部 分小区进行性能测量设置而无需对该分组内的所有的小区都进行性能测量任 务配置, 从而起到简化网管性能管理操作, 减少网管性能管理数据的效果。
作为另一个实例, 即在同一个 Cloud Group中, 各个 RRU生成的 small cell 看做是 Macro小区的一部分, 所有 small cell与 Macro小区共享相同的小区 ID。 这时, 由于 small cell与 Macro小区共享相同的小区 ID在小区组内无法区分各小 区, 那么可以为小区组内的小小区分配小区组内唯一的识别标识, 以下给出了 两个可选方案的举例:
方案 1 ( optionl )、 在 macro小区配置信息中插入一个属性项 GroupCellAttributes , 用于描述 small cell的相关信息, 该属性项可以是一个数 组或者列表(list) , 每个数组项或者 list成员 (member )对应一个 small cell信 息, 与 small cell编号对应。
方案二 ( option2 )、 在 macro小区配置信息中增加相应的子实例 SubCelllnstance , 每个 small cell作为 macro的一个子实例 , 包含 small cell编号和 该 small cell特有的配置参数。
如下表 1所示, 在 Macro cell属性表里增加 Groupld属性(另一种实现方式 是无需新增单独的分组标识 Groupld, 直接用该 Macro cell ID作为分组标识即 可), GroupCellAttributes属性或者 SubC stance属性。

GroupCell Attributes 0 M M
( optionl ) SubCelllnstance ( option2 ) 0 M M
在表 1中, GroupCellAttributes或者 SubCelllnstance中只包含 small cell本身 i^'J如 , GroupCellAttributes:
{(picol, attr 11 ,attr 12,attr 13 , .
(pico2, attr21 ,attr22,attr23 , ..
(picon, attrn 1 ,attrn2,attrn3 , )} ;
或者,
SubCelllntance:
picoID, attrl,attr2,attr3,
以上实施例中, 对于这种多个 small cell和某一个 Macro 小区共享小区 ID 的情况, NRT的修改变化是, 不仅仅需要在 NRT表中列出 Macro小区的信息, 还需要列出各个 small cell的信息, 用来标明 small cell与 Macro以及其他 small cell之间的关系。 由于 small cell的 ID都相同, 因此可以采用如 RRU编号等方式 对各个 small cell进行区别。
对每个 Group内的小区配置好 group ID之后, 可以在后续的网管配置操作 里, 进行有针对性的优化操作。 例如, 执行配置管理的对象资源查看操作时, 对具有相同 group ID的 small小区可以进行抽样查看而无需查看该分组内的所 有的 small小区配置数据, 从而起到简化网管操作, 减少网管负担的效果。
以上两个举例为小区组内的小区管理,小区组之间也可以引入相应的配置 管理。 具体举例如下:
由于分组标识已经在小区的配置属性里面体现了,因此可以只需要增加相 邻小区组的管理即可,即引入邻组关系表用来表示某个小区组与其它小区组的 相邻关系。 实现方式可以是采用关系数据库的表形式: 每个小区组都含有一张 邻组关系表,邻组关系表中的每一条记录可以标识某一个相邻的分组, 可以直 接记录相邻分组的标识。 例如, 如表 2所示, 某个分组 A可以具有如下的邻组 关系表, 表示该分组 A和分组 X、 Y、 Z...R都有相邻关系。
表 2 序号 邻组标识
1 X
2 Y
3 Z
N R
配置好邻组关系表之后, 可以在后续的网管配置操作里, 进行有针对性的 优化操作。 例如, 执行配置管理的对象资源查看操作时, 对具有相邻组关系的 小区组可以进行抽样查看而无需查看网管系统内的所有小区组配置数据,从而 起到简化网管管理的作用。
以上方案可以对 Hetnet小区进行分组管理, 从而减少操作管理维护
( Operations Administration Maintenance , ΟΑΜ )的交互, 减轻 ΟΑΜ的负担, 提高配置管理效率; 通过对小区关系属性的定义, 明确 group中小区之间的关 系, 更有利于对 Hetnet小区的管理。

可选地, 上述处理器 802, 还用于若上述小区组包括第二小区, 并且上述 第二小区为上述第一小区覆盖范围内的同频小区,确定上述第一小区和上述第 二小区是否共享小区标识; 若上述第一小区和上述第二小区共享小区标识, 为 上述第一小区分配上述小区组内用于指示上述第一小区的第一标识,为上述第 二小区分配上述小区组内用于指示上述第二小区的第二标识,上述第一标识与 上述第二标识不同,并且上述第一标识或上述第二标识还用于表示上述第二小 区为上述第一小区覆盖范围内的同频小区。
可选地, 上述处理器 802, 还用于若上述小区组包括第二小区, 并且上述 第二小区为上述第一小区覆盖范围内的同频小区,确定上述第一小区和上述第 二小区是否共享小区标识; 若上述第一小区和上述第二小区不共享小区标识, 将上述第一小区当前的小区标识作为上述小区组内用于指示上述第一小区的 信息。
进一步地, 为了方便小区组之间的管理, 上述处理器 802, 还用于为上述 第一小区所在小区组配置用于指示与上述小区组相邻的小区组的信息。 管理以后的使用举例, 具体地: 上述处理器 802, 还用于从具有相同分组标识 的小区中选择小区。选择小区的方法可以是任意的预定规则, 例如依据具体需 要执行的操作确定的抽样算法, 具体如何规定本发明实施例不予限定, 以下给 出几种选择小区以后可能执行的操作的应用场景进行举例说明:
例如: 执行对配置管理的对象资源查看操作时, 对具有相同分组标识的小 区可以进行抽样, 查看抽样的小区的资源; 无需查看该分组内的所有的小区执 行不必要的配置数据,从而起到简化网管操作,减少网管负担的效果。又例如: 在进行网管性能测量任务的管理中,可以从具有相同分组标识的小区中抽样选 择部分小区,对抽样得到的小区进行性能测量设置, 而无需对该分组内的所有 的小区都进行性能测量任务配置,从而起到简化网管性能管理操作, 减少网管 性能管理数据的效果。
值得注意的是, 上述基站只是按照功能逻辑进行划分的,但并不局限于上 述的划分, 只要能够实现相应的功能即可; 另外, 各功能单元的具体名称也只 是为了便于相互区分, 并不用于限制本发明的保护范围。
与上述异构网络小区的配置管理方法, 对应地, 本发明实施例还提供一种 小区的识别方法, 该方法可以由网络管理系统执行, 该方法包括:
网络管理系统使用用于指示第一小区所在小区组的信息确定所述小区组; 网络管理系统在所述小区组内使用用于指示所述第一小区的信息确定第 一小区。
可选地, 该方法还包括: 网络管理系统判断在同一个小区组内的第一小区 和第二小区是否共享小区标识(该小区标识可以是 PCI ); 如果网络管理系统 判断出第一小区和第二小区共享同一小区标识,则网络管理系统根据用于指示 小区组内第一小区的第一标识确定第一小区,并根据用于指示小区组内第二小 区的第二标识确定第二小区; 更进一步, 网络管理系统还可以根据第一标识或 第二标识确定第二小区为第一小区覆盖范围下的同频小区。可选地,如果网络 管理系统判断出同一小区组内第一小区和第二小区不共享同一小区标识,则在 同一小区组内, 网络管理系统根据第一小区的小区标识识别出第一小区, 并根 据第二小区的小区标识识别第二小区。
应用本发明实施例提供的技术方案,网络管理系统不仅可以对小区进行分 组配置,还可以根据用于指示第一小区所在小区组的信息确定小区组并使用用 于指示该小区组内第一小区的信息确定该小区组内的第一小区,从而实现采用 分组的方式对小区的识别, 提高了网络管理系统对小区识别的效率。
相应地, 本发明实施例还提供一种小区识别装置, 该装置可以是网络管理 系统, 包括:
小区组确定单元,用于使用用于指示第一小区所在小区组的信息确定所述 小区组;
小区确定单元,用于在所述小区组内使用用于指示所述第一小区的信息确 定第一小区。
可选地, 该装置还包括: 判断单元, 用于在第一小区所在小区组包含第二 小区时, 判断第一小区和第二小区是否共享同一小区标识; 如果是, 小区确定 单元具体用于在小区组内使用第一标识确定第一小区,并且小区确定单元还用 于在小区组内使用第二标识确定第二小区, 更进一步, 小区确定单元还用于使 用第一标识或第二标识确定第二小区为第一小区的覆盖范围下的同频小区。
本发明实施例提供的小区识别的方法和装置,与本发明实施例提供的异构 网络小区的配置管理方法、装置和系统中的概念是一样的。对于小区识别的方 法和装置中没有详细说明的, 可参考配置管理方法、 装置和系统中的说明。
另夕卜,本领域普通技术人员可以理解实现上述各方法实施例中的全部或部 分步骤是可以通过程序来指令相关的硬件完成,相应的程序可以存储于一种计 算机可读存储介质中,上述提到的存储介质可以是只读存储器,磁盘或光盘等。
以上仅为本发明较佳的具体实施方式, 但本发明的保护范围并不局限于 此,任何熟悉本技术领域的技术人员在本发明实施例揭露的技术范围内, 可轻 易想到的变化或替换, 都应涵盖在本发明的保护范围之内。 因此, 本发明的保 护范围应该以权利要求的保护范围为准。
