- the network operation is adjusted according to the coordination proposal of the network operation. If there is a conflict between the operator's preset coordination proposal and the analysis coordination proposal determined based on the network information analysis, the above coordination proposal is adjusted to obtain the adjusted network operation coordination proposal. For network functions or network components that cannot be operated at the same time, if they are already running, they need to be terminated. For network functions or network components that need to be coordinated or run simultaneously, if they are closed or disabled, they need to be started.
- the operator's preset network operation coordination proposal can specify which KPIs correspond to what network functions or network components to coordinate and optimize, which may be one or more. There may also be conflicts between the preset coordination proposals of this or more operators, so when adjusting the coordination proposal, you can make judgments and then make adjustments. There may also be one or more coordination suggestions for analysis based on analysis of network information. When adjusting coordination suggestions, it is possible to first determine whether these coordination proposals conflict and then make adjustments.

- some network operations may invoke the same or interrelated network functions or network components (specifically SON function or SON component), and it is considered that these network operations are conflicting.
- some networks Network functions or network components are not independent of each other.
- a network function or network component When a network function or network component is invoked, it affects other network functions or network components that are associated with this network function or network component. Therefore, when it is judged whether there is a conflict in the network operation, if it is determined that the network operation conflicts with other network operations, the network operation associated with the network operation is also considered to be a conflicting network operation.
- the above coordination proposal should be adjusted, and the preset coordination proposal and the analysis coordination proposal should be arbitrated, so that the adjusted coordination proposal is as much as possible. Avoid conflicts in network operations.
- the basis for the adjustment may be a built-in logic or a pre-configured policy, wherein the built-in logic or the pre-configured policy may include a threshold judgment, a priority judgment, a weighted value ranking, and the like.
- the network coordinator when the network coordinator obtains coordination suggestions for network operations, the network coordinator gives different priorities for coordination of different network operations.
- the network coordinator adjusts the coordination proposal of the network operation according to the priority. For example, for a conflicting coordination proposal, exclude the lower priority coordination proposal. Select the highest priority coordination proposal as the adjusted coordination proposal for the network operation. Or, according to the priority or weighted value of the coordination proposal, the integrated scheduling network operation is used as the adjusted coordination proposal.
- the network operation can satisfy the network target implementation requirements as much as possible.
- the coordination proposal of the network operation may also be a coordination proposal of the network operation manually sent to the network coordinator. Usually, the coordination proposal of the network operation manually issued has the highest priority, and at this time, the network coordination It is not necessary to use the preset coordination proposal and the analysis coordination proposal to prioritize the coordination proposal through the network operation manually issued.

具体实施方式
下面通过附图和实施例, 对本发明的技术方案做进一步的详细描述。 为了实现在网络规划、 部署、 优化和维护阶段自动化的过程, 本发明 实施例引入了自组织网络(英文为 Se lf-Organized Network, 筒称 S0N )。 为了使得本发明实施例更加清楚和完整, 本发明实施例以 SON为例, 但本 领域技术人员可以理解, 本发明实施例并不限于 SON, 例如本发明实施例还 可用于计算机网络中的网络操作以及无线通信网络中的任何网络操作。
下面先对本发明实施例中一些概念和术语进行定义和说明。
在本发明实施例中, 网络功能(例如 SON功能)。 相应地, 网络组件包 括 SON组件(英文为 SON Groupware )。 相应地, 网络操作包括 SON操作。
网络功能, 例如 SON功能, 具有实现不同网络预期目标的功能。 网络 组件, 包括具有固定协调关系的网络功能构成的, 例如, SON组件(英文为 SON Groupware )可以包括 SON功能固定的调用或固定的调用顺序等等。 这 里需要说明是的, SON组件一般所具有的固定关系(例如 SON功能的调用或 者调用顺序)不会随着网络场景变化而变化。 典型的 SON组件, 例如, C0C 后调用 ANR;节能(英文为 Energy Saving ,筒称 ES)后调用 COC,再调用 ANR; MR0优化后调用 MLB。 通常情况下, 这些 SON功能组合在一起就构成相应的 SON组件, 它们在网络布署时就由网络配置好。 SON组件的固定关系, 一般 可以由运营商或供应商以策略的形式固定配置, 即预配置。 SON组件关系可 保存于网元或网管中, 其中, 网管可以是集成参考点管理者 (英文为 Integrat ion Reference Point Manger , 筒称 IRPManger ), 或集成参考点 代理 (英文为 Integra t ion Reference Po int Agent , IRPAgent )中。 IRPManger 可以是运营商的网管系统(英文为 Network Management Sys tem,筒称匪 S ), IRPAgent可以是供应商的网管系统(英文为 Element Management Sys tem, 筒称 EMS )。
本发明实施例中网络操作 (例如 SON操作)就是实现网络功能 (例如 SON功能)或者由具有固定协调关系的网络功能构成的网络组件(例如 SON 组件) 的实现过程。
在本发明实施例中, 不同的网络功能 (例如 SON功能 )之间的协作调 用, 调用中相关数据的共享、 传递等等, 都可以称为网络操作的协调。
不同的网络操作 (例如 SON操作)操作具有不同的独立功能, 包括但 不限于: 小区失效补偿 (英文为 Ce l l Outage Compensat ion, 筒称 COC ), 覆盖容量优化 (英文为 Coverage and Capac i ty Opt imizat ions , 筒称 CCO ),
自动邻区关系 (英文为 Automatic Neighbor Relationship, 筒称 ANR ), 移动性优化(英文为 Mobility Robust Optimization, 筒称 MR0), 移动性 负载平衡(英文为 Mobility Load Balance, 筒称 MLB)等。 图 1为本发明实施例提供系统构架示意图。
图 1所述的系统架构示意图中的主体为网络协调者, 例如 SON协调者 (英文为 SON Coordinator )0 网络协调者可以独立存在于各个网元和网管 系统中, 也可以在各个网元内部或网管系统内部。 例如网络协调者可位于 网元, 或 IRPManger上, 或 IRPAgent中, 其中, IRPManger与 IRPAgent通 过北向接口进行信息传递。
网络协调者可以调度不同的网络功能或网络组件以实现不同的网络目 标。
作为一个示例, 网络协调者可以确定调用哪些网络功能或者网络组件, 以及哪些网络功能或网络组件被先调用, 哪些网络功能或网络组件被后调 用。 网络协调者还可以根据不同的网络目标, 订制不同的网络组件, 其中, 这些订制的网络组件可以是网络功能的重组, 也可以网络功能的相互调用 或者调用顺序的先后的重组。 例如, 在发生网络故障时, 网络协调者可以 针对排障建立一组分析 /排障的协调架构, 通过网络信息的采集, 按一定的 顺序判断问题的根因, 并仲裁多个网络功能或网络组件间的调用关系, 自 动排除网络故障。 除此之外, 网络协调者还可以对实现同一网路目标的不 同的网络功能或网络组件进行优选, 监控 KPI 变化, 完成网络环境的配置 参数以及不同网络环境下的性能测量值的保存, 将网络进行回退, 启动或 终止网络功能或网络组件等等。 网络协调者还可以监控哪些网络功能或者 网络组件在运行过程中, 改动了多少基站或小区、 这些基站或小区的哪些 参数被修改、 某些网络功能或网络组件启动要求有哪些等等问题。 例如, 网络协调者可以启动并通知 ANR相关信息, 加入新小区或更新删除小区的
邻区关系, 可以有效防止等待延时造成的服务质量受损, 减少基站计算负 荷。 例如, 网络协调者还可以当 MR0优化后, 通知 MLB的 CI0值, 以便 MLB 按新更改的 CI0值进行优化调整。 例如, 在 MR0进行优化过的小区或基站, 其 CI0都被更改, 这些小区或基站可由网络协调者通知到 MLB, 以便对相应 范围内的小区或基站进行调整, 而不会对不相干的区域重调整。
图 1中的网络协调者包括 B类网络协调者和 A类网络协调者。具体地, B类网络协调者可以分析网络状况, 重新组合不同网络功能(例如网络功能 1 )或网络组件(例如, 由网络功能 2、 网络功能 3和网络功能 4构成)之 间的关系。 在网络协调启动后, B类网络协调者为高层的网络协调单元, 因 而也可以称为上层网络协调者。 B类网络协调者的下层可以为 A类网络协调 者, 或者网络功能或者网络组件。 一般情况下, A类网络协调者可独立配置 网络功能和网络组件, 分别完成各自的网络目标。 但如果存在 B类网络协 调者, 就需要统一由 B类网络协调者来协同操作, 其中, 这些协同操作包 括网络功能或网络组件调用、 调用顺序、 传递参数、 等待时长、 冲突时的 互斥、 KPI保障等。 受 A类网络协调者调度的网络功能或网络组件也统一由 B类网络协调者调度, 而不能自由修改网络配置。 因而, 这种协调模式称为 集中式协调模式。 相应地, 对于只存在 A类网络协调者而不存在 B类网络 协调者时, A类网络协调者可以自由修改网络配置,而满足各自的网络目标, 因而这种协调模式称为分布式协调模式。
更进一步说明, 集中式协调模式, 指所有网络功能或网络组件运行时, 或在操作网元或网络配置参数时, 都需要向 B类网络协调者发起请求, 经 过 B类网络协调者响应后才进行操作。 在集中式协调模式下, 网络功能或 网络组件的运行结果以及参数改动等都需要向 B类网络协调者上报。 分布 式协调模式, 指网络功能之间直接进行相互调用, 由于不存在 B类网络协 调者, 所以不必由 B类网络协调者统一调度, 分布式协调模式下, 网络协 调者(具体为 A类网络协调者)相当于一个开关, 用于指示当前是进行协
调还是无协调。 这里的无协调, 是指网络协调者不工作, 或不起作用, 网 络功能或网络组件可以自由运行, 修改网络配置参数, 此时, 可以不考虑 网络冲突等由于网络功能或网络组件引起的网络问题。
本发明实施例中,Β类网络协调者或者 Α类网络协调者可以就是网络功 能或网络组件, 这些网络功能或网络组件具有管理和调度下层网络功能或 网络组件的作用。 B类网络协调者或 A类网络协调者更注重管理和调度功能, 可以不参与下层的网络操作 (例如 COC , CCO, ANR, MR0或 MLB等等)。
图 1所示的系统架构图中, 网络协调启动后, 在集中式协调模式下, B 类网络协调者分析网络状况, 并统一调度网络功能或网络组件, B类协调者 根据分析的网络状况获取网络操作的协调建议, 并对小区、 基站等网络资 源进行网络操作。 如图 2所示, 本发明实施例一方面提供一种网络协调的方法。 本发明 实施例提供的网络协调的方法是基于图 1 所示的本发明实施例中提供的系 统架构下进行的, 该方法包括以下内容。 本发明实施例的执行主体可以是 网络协调者(例如 SON协调者), 其中,网络协调者可以是 B类网络协调者 (例如 B类 SON协调者),也可以是 A类网络协调者(例如 A类 SON协调者)。
S200 , 接收或监控网络信息。
可选地, 网络信息包括但不限于以下信息之一或组合:
关键绩效指标 KPI、告警监控信息、终端故障报告、终端测量数据信息、 性能测量信息、 最小化路测信息、 用户抱怨、 网络操作请求和无线链路失 败信息。
上述网络信息之一或组合都可以触发网络协调者判断网络操作是否进 行协调。 例如, 网络操作不满足当前网络的预期目标(可以体现在 KPI 不 满足预置条件, 或者告警监控信息发来告警信息, 或者用户抱怨表明当前 用户体验降低, 或者无线链路失败信息, 或者网络操作请求指示需要进行
网络操作的协调等等), 则网络协调者会判断出网络操作需要进行协调, 从 而使得网络操作能够尽可能满足网络的预期目标。 其中, 网络操作请求包 括网络内部的网络操作请求和通过人工下发的网络操作请求, 该通过人工 下发的网络操作请求通常具有最高优先级。 如果网络协调者接收或监控到 网络信息包括通过人工下发的网络操作请求时, 则可以立即判断出当前网 络操作需要协调, 而不用网络协调者再综合其他网络信息进行判断网络操 作是否需要进行协调。
作为一个示例, 网络协调者可以接收或监控上述网络信息。 由于网络 协调者可以在独立于各个网元或网管系统, 也可以在各个网元或网管系统 设备(例如基站、 基站控制器、 中继站等等), 或者核心网设备(例如移动 管理实体、 各种网关), 还可以是用户终端等。 网络协调者接收或监控网络 信息, 可以通过现有接口 (例如, 基站与基站之间是 X2口, 基站与移动管 理实体之间通讯接口是 S1口, 用户终端与基站之间是空口, 网管系统之间 是北向接口等等), 也可以通过自定义接口, 实现网络协调者接收或监控网 络信息。
S201 , 根据网络信息判断网络操作是否需要协调。
可选地, 本发明实施例中, 网络协调者根据网络信息判断出网络操作 需要协调, 包括以下情况之一或组合:
根据上述网络信息分析出所述网络操作存在冲突;
根据上述网络信息分析出所述网络操作包括需要调用多个网络操作。 本发明实施例中, 网络操作 (例如 SON操作) 包括实现一个或多个网 络功能或网络组件的过程。 对网络操作进行协调, 包括两种类型的协调问 题:
第一类协调问题是资源冲突型协调 (也可以称为网络操作存在冲突)。 也就是说, 网络操作 (具体可以在实现网络功能或网络组件的过程) 同时
或先后对相同的参数、 小区、 基站、 天线等网络资源进行操作而导致的冲 第二类协调问题是网络操作包括需要调用多个网络操作时,为保障 KP I 不被先后运行的网络操作恶化, 而需对先后运行的多个网络操作进行调度。 由于不同的网络操作各有不同的网络目标(例如 KPI不同), 运行中可能出 现前一个网络操作运行后, 提升了某个 KPI指标, 后一个网络操作运行时, 由于各自的网络目标不同, 在提升自己 KPI 指标的同时, 却降低了之前已 经提升的 KPI 指标, 从而导致进行了多个网络操作后, 反而效果不如进行 一个网络操作的所要达到的效果。 在第二类协调问题中, 这时还需要排序 多个网络操作的实现目标, 并对 KPI 进行监控, 及时终止造成恶化效果的 网络操作, 或者将网络回退到进行该网络操作之前。
更进一步地, 本发明实施例中的 KPI 的类型包括切换类 KPI、 覆盖类 ΚΡΙ、 负载类 KPI以及服务质量类 KPI等等。 对于不同的 KPI类型, 对应不 同类型的网络问题, 其相应的分析过程也有所不同。
本发明实施例中所述的冲突, 由以下因素之一或组合产生:
网络操作的操作区域相同、 操作对象相同、 操作区域之间互为邻区 /邻 站、操作对象互为邻区 /邻站、操作参数相同、操作参数之间具有固定关系、 网络操作的操作间隔时长在冲突时间段内等等。
可选地, 本发明实施例中的网络操作可以是网络内部的网络操作, 也 可以是由人工下发的网络操作。 由人工下发的网络操作通常具有最高优先 级, 如果网络协调者判断出当前网络操作中包括由人工下发的网络操作, 则对于网络协调者不用判断当前网络操作是否需要进行协调, 可以优先执 行由人工下发的网络操作。 在执行完由人工下发的网络操作后, 如果当前 网络操作中不包括由人工下发的网络操作, 网络协调者可以根据网络信息 判断当前网络操作是否需要进行协调。
S202 , 如果根据上述网络信息判断出网络操作需要进行协调, 对该网
络操作进行协调。
网络协调者对网络操作进行协调的过程中, 获取网络协调建议, 这些 协调建议是根据运营商的预置的协调建议, 或者根据对网络信息进行分析 而菝得的。
作为一个示例, 对于第一类协调问题或第二类协调问题, 网络协调者 可以针对具体的网络操作, 启动网络分析流(例如根据当前为网络切换类 的网络操作冲突, 则启动切换类 KPI分析流), 调度各个网络操作的相互调 用或者调用顺序, 使得网络操作不再冲突, 而使得能够到达网络的预期目 标。 其中, 启动网络分析流的过程, 可以在仿真环境下进行, 也可以在实 际的网络环境下进行。
应用本发明实施例提供的技术方案, 根据对接收或监控的网络信息判 断网络操作是否需要进行协调, 进而可以及时对网络操作进行协调, 尽可 能避免了由于网络操作是固定的或者由运营商预置而可能产生各种网络问 题的出现, 使得网络操作能够达到预期的网络目标, 从而降低了运营商的 网络维护成本。
如图 3-1 所示, 本发明实施例另一方面提供一种网络协调方法。 本发 明实施例提供的网络协调方法是对如图 2 所示的实施例的具体细化。 对于 图 2 所示实施例中相同的步骤和概念不再赘述。 本发明实施例所述方法, 包括以下内容。
作为一个示例, 本发明实施例是对图 2 中 S202的细化和扩展, "对网 络操作进行协调", 如图 3-1所示, 包括:
S 301 ,获取网络操作的协调建议。
可选地, 网络协调者判断出是第一类协调问题, 还是第二类协调问题, 并针对第一类协调问题或者第二类协调问题确定网络操作的协调建议。
可选地, 网络操作的协调建议包括但不限于:
运营商的预置协调建议, 和 /或, 根据对网络信息进行分析确定的分析
协调建议。
运营商的预置协调建议, 是由运营商在针对不同的第一类协调问题或 不同的第二类协调问题确定的网络操作的协调建议。 运营商的预置协调建 议可以在网络部署的时候, 就配置好, 也可以由网管或网元在进行网络操 作之前进行预置。 网络协调者可以根据第一类协调问题还是第二类协调问 题有针对性的使用运营商的预置协调建议。 如果网络操作的协调建议中仅 包括运营商的预置协调建议, 则网络协调者可以不用再进一步根据第一类 协调问题或第二类协调问题分析, 使用该运营商的预置协调建议即可。
可选地, 网络协调者还可以对网络信息进行分析, 从而确定分析协调 建议, 如图 3-2所示, 可以包括:
S301-1 , 进行物理小区标识 (英文为 Phys ica l Ce l l ID , 筒称为 PCI ) 检测, 并判断 PCI冲突检测是否无效。
S301-2 , 如果判断出上述 PCI 冲突检测无效, 则进行邻区漏配检测或 调用 ANR, 并判断该邻区漏配检测或调用 ANR是否无效。 如果判断出 PCI冲 突检测有效, 则网络协调建议可以指示网络协调者调用用于解决 PCI 冲突 检测的网络功能或网络组件,
S301-3 , 如果判断出上述邻区漏配检测或调用 ANR无效, 则进行射频 RF问题检测或者进行无线资源管理 RRM问题检测。 如果判断出领取漏配检 测或调用 ANR有效, 则网络协调建议中可以指示网络协调者调用用于解决 邻区漏配检测或调用 ANR的网络功能或网络组件。
S301-3 , 如果 SON协调者判断出上述邻区漏配检测或调用 ANR无效, SON协调者根据 KPI判断进行 RF问题检测或者进行 RRM问题检测。
S 301-4 , 进行 RF问题检测。 如果 RF问题检测有效, 则根据 RF问题订 制协调建议.
S301-5 , 进行 RRM问题检测。 如果 RRM问题检测有效, 则根据 RRM问 题订制协调建议。
S 301-6 , 根据上述 S 301-1至 S 301-5所述不同的网络问题确定分析协 调建议。 例如, COD检测有效, 则调用网络功能中的 COD功能; 如果 COD检 测无效, 则还需要进行其他 RF问题检测或者 RRM问题检测。
S 301-7 , 如果 RRM问题检测 (例如, e lCIC检测调整 CI0、 MRO检测调 整步长和 MLB按 MR0设定的基准 CI0调整问题)或者 RF问题检测(例如 COD 检测、 UL/DL检测和 Weak Coverage检测)都无效, 则表明检测的小区正常, 只是负载低, 可以节能 ES。
作为一个示例, 所述 RF问题检测包括以下之一或组合:
COD检测、 UL/DL检测和 Weak Coverage检测。
作为一个示例, 所述 RRM问题检测包括以下之一或组合:
e lCIC检测调整 CI0、 MRO检测调整步长和 MLB按 MR0设定的基准 CI0 调整问题。
S 302 , 根据所述网络操作的协调建议, 对所述网络操作进行协调。 本发明实施例的一个示例, 包括:
SON协调者判断网络信息中的 KPI数据下降是否是由于网络覆盖出现了 严重(例如 KPI不满足预置的条件 )的小区失效问题。 SON协调者通过分析 多个 KPI数据(比如: 小区接入 /切换成功率,小区吞吐量,小区用户数等), 以及告警和跟踪 (Trace )信息的分析处理得出 COD是否无效。
如果 SON协调者得出 COD检测有效, 则网络操作的协调建议中包括调 用解决 COD问题的 SON功能或 SON组件, 这些 SON功能或 SON组件可以是 预置的。
如果 COD检测无效, 即没有发现小区失效, 则进行其他检测 (例如, UL/DL检测和 Weak Coverage检测等)。 需要进行说明的是, 进行 COD检测、 UL/DL检测和 Weak Coverage检测的顺序不限, SON协调者在进行哪个检测 发现其有效时, 则在分析协调建议中包含解决该检测对应问题的 SON功能 或 SON组件, 例如, 发现 COD检测有效, 则在分析协调建议中指示需要调
用 COD功能以解决 COD检测的问题。 解决上述问题的 SON功能或者 SON组 件可参见现有技术, 这里不再赘述。
本发明实施例的另一个示例。 如果 COD检测无效, 则 SON协调者进行 UL/DL检测。 SON协调者采集 KPI数据异常小区相关的上、 下行终端测量数 据、 MDT测量报告、 无线链路失败测量报告, RRM测量 ^艮告, 以及上、 下行 性能测量信息, 时间戳, 判断小区是否发生覆盖上、 下行不平衡。 如果发 现上下行不平衡, 则协调建议中包括调用解决该问题的 SON功能或 SON组 件。 如果未发现上下行不平衡, 则验证覆盖中的场景是弱覆盖、 过覆盖还 是导频污染。 SON协调者采集终端测量数据或 MDT测量 ^艮告 (尤其是 A2或 A3事件触发的测量报告), 进行判断, 是否邻区间存在较大的干扰, 以及信 号差值小的事件。 如果邻区间存在较大干扰, 则协调建议中包括解决该问 题的 SON功能或 SON组件, 这些 SON功能或 SON组件可以是预置的。 如果 上述检测均无效(包括所有的 RF和 RRM问题), 则属于正常的小区, 只是 轻负荷。 协调建议中可以包括不协调的建议, 即不对网络操作进行协调。
本发明实施例中, 网络协调者可以根据网络信息判断是否满足以下条 件之一或组合,判断上述检测是否无效: KPI改善(例如,对于接入成功率、 切换成功率等, KPI上升或 KPI高于某一预设门限; 对于呼叫失败率、 重试 连接失败率、 呼叫时延等, KP I下降或 KPI低于某一预设门限)、 告警减少 或消失、 终端测量数据改善(例如参考信号功率、 参考信号质量或信噪比 的测量值的减少量大于历史减少量 ) 以及无线链路失败报告减少或消失等。
更进一步, 本发明实施例提供的网络协调的方法, 在对网络操作进行 协调之前, 还可以包括:
对上述网络操作进行网络协调准备, 以使在所述网络协调准备后对所 述网络操作进行协调;
其中, 该网络协调准备包括以下过程之一或组合:
获取网络操作中的网络功能或网络组件的部署信息、 状态信息及影响
范围信息(例如, SON功能或 SON组件被部署在哪些网元或网管设备中, 这 些网元或网管设备中都部署了什么 SON功能或 SON组件; SON功能或 SON组 件的状态是否可用; SON功能或 SON组件的影响区域, 跟踪区 /位置区 /路由 区, 影响的网元等);
获取网络操作中的网络组件的固定关系 (例如,网络组件中的功能的先 后调用关系、 网络组件中网络功能之间传递的参数、 网络组件中的网络功 能优先级、 网络组件中网络功能的互斥时的取舍关系, 或网络组件中玩过 功能调用时的触发条件等等);
对网络操作中的网络功能或网络组件设置网络操作的协调模式(例如 集中式协调模式或分布式协调模式;);
停止网络操作中的网络功能中冲突的网络功能或网络组件中冲突的网 络组件。
网络协调者可以进行网络协调准备, 该网络协调准备在对网络操作进 行协调之前完成。 更进一步地, 在网络协调者进行网络协调准备的过程中, 还可以对网络功能的运行开关进行设置, 或者进行网络配置参数预存、 运 行结果回调等。 网络协调者还可以设置网络功能的之间相互关系, 这种相 互关系可以通过标识进行关联。
更进一步, 在网络协调者进行网络协调准备的过程中, 网络协调者对 于将用于进行网络操作的协调的网络功能或网络组件, 先禁止运行, 以便 保持网络环境的稳定, 防止在进行网络操作的协调时已经有网络操作未经 过网络协调者进行调度而独立运行可能造成网络操作的协调失败, 并且可 以为调整网络操作的协调建议后, 重新设定调度顺序提供。 网络协调者可 以通过网络协调准备获取网络操作之间的关联关系或运行策略, 对相互关 联的网络操作进行禁止; 对于无关联关系的网络操作则无需网络协调者进 行调度。
作为一个示例, 可以在网络的协调准备中设置所述网络操作的协调模
式, 包括集中式协调模式和分布式协调模式。 相应地, 在集中式协调模式 下, 所有的网络操作由 B类 SON协调者统一调度, 从而实现网络目标。 而 在分布式协调模式下, A类 SON协调者可以修改网络配置, 调度网络操作。
作为一个示例, 本发明实施例中所述的协调操作建议包括以下之一或 组合: 所述网络操作的调用 (例如, CC0-ANR的调整, 或者 ANR-CC0优化等 等), 调用顺序, 调用参数, 调用优先级信息, 所述网络操作的持续时长。
针对上面所述, 这里再举一个具体例子, 该例子是在集中式协调模式 下进行的。 图 4为本发明实施例另一方面提供的网络协调方法, 如图 4所 示, 包括如下处理过程:
( 1 ) B类 SON协调者进行网络协调准备, 并接收或监控网络信息, 该 网络信息中包括 B小区的 KP I。
( 2 ) B类 SON协调者监控到 B小区 KPI下降, 例如吞吐量下降很多, 接入成功率高, B小区将发起请求到 B类 SON协调者请求进入 ES功能。 在 B小区请求进入 ES时, B类 SON协调者先阻止 B小区马上进入 ES状态, 同 时, 禁止 B小区的相关联小区的网络操作, 例如 A、 C邻小区的 SON操作。
( 3 ) B类 SON协调者对 B小区进行邻区检测、 PCI冲突检测, 判断是 否发生邻区失效或存在未知邻区的情况。
( 4 )如果不是, 且 KPI满足预置阈值(例如 KPI«80% ), 则 Β类 SON 协调者启动 COD检测判断是否 B小区失效了, 这时需要使用最小路测信息, 无线链路失败信息, 告警信息以及与 B小区有关的信息进行分析。
( 5 )如果 B小区未失效, 则允许 B小区进入 ES。 同时协调 B小区的邻 区, 即 、 C小区, 并选择其中一个或两个小区对 B小区覆盖进行补偿, 例 如通过激活 A、 C小区的 C0C功能。
( 6 )激活 A、 C小区的 ANR功能, 进行邻区关系调整。
( 7 )协调 MR0组件( MR0 MLB )对更新邻区关系的 A、 C小区新的切 换关系进行优化, 最后的 MLB可使 A、 C小区在 B小区进入节能后, 重新保
证新的覆盖时, 仍能均衡地分散业务。
本发明实施例中, 当协调建议包括运营商预置的协调建议和根据对网 络信息进行分析确定的分析协调建议时, 判断运营商的预置协调建议和根 据对网络信息进行分析给出的分析协调建议是否存在冲突。
如果不存在冲突, 则根据网络操作的协调建议对网络操作进行调整。 如果运营商的预置协调建议和根据对网络信息分析确定的分析协调建 议之间存在冲突, 则对上述协调建议进行调整, 得到调整后的网络操作的 协调建议。 对于不能同时运行的网络功能或网络组件, 如果已经运行, 需 要进行终止; 对于需要进行协调先后运行或者同时运行的网络功能或者网 络组件, 如果出于关闭或禁止运行状态, 则需要启动其运行。
更进一步, 运营商的预置网络操作协调建议, 可以指定哪些 KPI对应 什么样的网络功能或网络组件进行协调优化, 其可能为一个或多个。 这一 个或多个运营商的预置协调建议之间也可能存在冲突, 因而在调整协调建 议时, 可以先进行判断, 再进行调整。 对于根据对网络信息分析确定的分 析协调建议也可能为一个或多个, 在调整协调建议时, 可以先判断这些协 调建议之间是否冲突, 再进行调整。
具体地, 上述冲突可以由以下因素之一或组合产生:
网络操作的操作区域相同、 操作对象相同、 操作区域之间互为邻区 /邻 站、操作对象互为邻区 /邻站、操作参数相同、操作参数之间具有固定关系、 网络操作的操作间隔时长在冲突时间段内和网络操作被同时调用等。
例如, 当网络操作的操作对象为同一小区, 在该小区一定数量的邻区, 假如小区周围 3层, 共 32个邻区, 或某路径下、 某个方向上的若干邻区, 当网络操作对这个小区或这些邻区进行操作时, 均可认为冲突。
再例如, 某些网络操作调用其它的网络操作的过程中, 可能调用了相 同或相互关联的网络功能或网络组件(具体为 SON功能或 SON组件 ), 此时 认为这些网络操作是存在冲突的。 更进一步, 由于在实际网络中, 某些网
络功能或网络组件不是相互独立的, 调用某个网络功能或网络组件的同时, 会影响到与这个网络功能或网络组件相互关联的其它网络功能或网络组 件。 因此, 在判断网络操作是否存在冲突时, 如果判断出这个网络操作与 其它网络操作存在冲突, 则与这个网络操作相互关联的网络操作, 也认为 是冲突的网络操作。 对于如果上述预置协调建议和上述分析协调建议之间 存在冲突的网络操作时, 应对上述协调建议进行调整, 并对预置协调建议 和分析协调建议进行仲裁, 使得调整后的协调建议尽可能的避免网络操作 存在冲突。 调整的依据可以为内置逻辑或预配置的策略, 其中, 内置逻辑 或预配置的策略可以包括阈值判断、 优先级判断、 加权值排序等方法。
作为一个示例, 网络协调者获取网络操作的协调建议时, 网络协调者 赋予不同网络操作的协调建议不同优先级。 当预置协调建议和分析协调建 议中包括的网络操作存在冲突时, 网络协调者根据优先级调整网络操作的 协调建议。 例如, 对于存在冲突的协调建议, 排除优先级较低的协调建议 选取优先级最高的协调建议作为调整后的该网络操作的协调建议。 或者按 照协调建议的优先级或加权值排序进行综合调度网络操作作为调整后的协 调建议, 按照这种调整后的协调建议能够使得网络操作能够尽可能的满足 网络目标的实现要求。 更进一步, 网络操作的协调建议, 也可以是通过人 工下发给网络协调者的网络操作的协调建议, 通常这种通过人工下发的网 络操作的协调建议具有最高优先级, 此时, 网络协调者不需要使用预置协 调建议和分析协调建议, 优先执行通过由人工下发的网络操作的协调建议。
可选地, 本发明实施例所述的方法, 还可以包括:
对网络操作进行协调之前, 保存不同网络环境下配置参数以及不同网 络环境下的网络性能值, 并为不同网络环境赋予不同的编号或步骤号或顺 序号。
根据不同网络环境的编号或步骤号或顺序号, 不同网络环境下配置参 数以及不同网络环境下的网络性能值, 将网络回退到对网络操作进行协调
m。
网络协调者保存不同网络环境下配置参数以及不同网络环境下的网络 性能值, 可以使得网络协调者根据网络操作的协调建议或调整后网络操作 的协调建议进行网络协调后, 发现 KPI 恶化或需要重新确定协调建议时, 需要回退到对网络操作进行协调之前。 网络协调者在保存不同网络环境下 配置参数以及不同网络环境下的网络性能值, 在对网络操作进行协调的过 程中, 可能由于网络目标的实现要求改变或者需要达到最理想的网络实现 目标, 可能需要多次对网络操作进行协调, 因而, 网络协调者在保存不同 网络环境下配置参数以及不同网络环境下的网络性能测量值时, 可以赋予 不同网络环境以不同的编号或顺序号或步骤号, 以使得网络协调者在需要 进行回退网络的时候, 可以更准确地将网络回退到某个编号或顺序号或步 骤号的网络协调之前的网络, 甚至是某个具体的网络操作。 这里的编号或 顺序号或步骤号可以是按照网络操作的时间顺序进行排列, 也可以是预置 的索引号, 并分别对应不同的网络环境或者不同的网络操作。
针对本发明实施例所述的方法, 再一个具体示例, 如图 5所示, 包括: ( 1 ) SON协调激发。
SON协调者接收到告警 /故障 /用户抱怨, KPI , 或者 SON请求, 这些信 息表明网络操作需要进行协调。
( 2 ) SON协调准备及分流。
SON协调者进行网络操作的协调准备,在网络操作协调准备完成后, SON 协调者收集与网络操作相关的 KPI (例如, 切换类 KPI、 覆盖类 ΚΡΙ、 负载 类 ΚΡΙ等等), 并根据不同的 ΚΡΙ启动不同的 ΚΡΙ分析。
( 3 )排障分析 /运营商策略获取。
SON协调者根据上述不同 KPI分析, 确定针对不同的网络问题, 确定分 析协调建议; SON协调者针对不同的网络问题,获取运营商的预置协调建议。
( 4 )如果分析协调建议和运营商的预置协调建议存在冲突, 则对分析
协调建议进行仲裁, 并调整协调建议。 SON协调者可以根据调整后的协调建 议对网络操作进行调整, 以使得调整后的协调建议能够使得网络操作尽量 避免冲突和能够满足网络目标的实现要求。
应用本发明实施例提供的技术方案,可以获知网络操作是否需要协调, 并对需要进行协调的网络操作进行协调处理, 从而降低运营商的维护成本。 并且本发明实施例提供的技术方案, 对网络操作协调建议进行判断, 并根 据判断结果进行调整, 可以尽可能地减少对网络操作中的冲突, 实现网络 目标的要求, 降低网络维护的成本。
