Description

网间协同的方法、 协同节点和网络侧设备 技术领域
本发明涉及通信领域, 并且更具体地, 涉及网间协同的方法、 协同节点 和网络侧设备。 背景技术
随着移动智能终端的大规模应用和无线通信带宽的需求日益增长, 无线 通信领域逐步引入新的通信制式和组网形态, 越来越多的运营商形成全球 移动通讯(Global System of Mobile communication, 筒称为 "GSM" )、 通用 移动通信系统 ( Universal Mobile Telecommunication System , 筒称为 "UMTS" ), 长期演进( Long Term Evolution, 筒称为 "LTE" ) 多制式、 宏 微多层网络并行运营态势。 LTE扁平化架构不同于 GSM和 UMTS的 3层架 构, 取消了基站控制器这一集中控制节点, 因此, 一方面, LTE基站间协调 需要引入 X2接口, 导致 LTE单基站的连接数量增加 5倍以上, 仍然无法从 网络层面最优化资源利用, 另一方面, LTE与 GSM和 UMTS之间不能有效 交换资源使用状态, 也限制了 GSM、 UMTS和 LTE—张网性能最优化和容 量最大化; 对于热点区域宏微组网场景, 小站主要部署于宏网的多层覆盖区 域, 需要在众多小站和多层宏网之间进行有效的协调, 才能最有效的提升网 络容量和终端客户体验。
现有技术中 LTE的演进型基站( Evolutional Node B, 筒称为 "eNodeB" ) 之间通过 X2接口来进行资源与状态信息交换, 协调 eNodeB之间的无线资 源优化使用; LTE和 GSM、 UMTS 之间通过核心网的无线接入网 (Radio Access Network, 筒称为 "RAN" )信息管理 ( RAN Information Management, 筒称为 "RIM" )信令接口来交互无线资源和状态信息, GSM与 UMTS之间 通过 Iur-G来交互无线资源和状态信息, 通过这些接口进行资源使用协调与 优化。 LTE eNodeB间通过 X2接口进行无线资源协调, 需要每个 eNodeB配 置大量的 X2接口, 导致资源协调有效性很大依赖于 X2接口配置的准确和 有效; 另一方面, 每个 eNodeB既是信息的发布者也是信息的汇聚分析体, 信息交互复杂, 协调困难。 LTE与 GSM和 UMTS通过 RIM消息主要面向 小区级信令传输, 由 LTE的 eNodeB获取 GSM和 UMTS网络资源情况, 进 行资源协调分析与判断; GSM和 UMTS之间通过控制器的 Iur-G接口进行 信令传输, 在控制器内进行 GSM和 UMTS的资源协调分析与判断; LTE、 UMTS和 GSM之间通过不同架构在不同的实体内分别进行资源协调分析判 断。 制式间交互状态后分别判决, 无法在一个统一的节点了解整网的趋势和 瞬间变化, 从而导致单制式最优, 但整网不是最优的情况, 无法最大化利用 网络资源提升网络性能和用户体验。 无线资源状态通过核心网来交换, 没有 在无线网络中完成自身的资源协调, 形成核心网和无线网络的紧耦合, 版本 升级中会带来跟多不确定因素, 不利于网络稳定。 发明内容

图 1示出了根据本发明实施例的网间协同的方法 100的示意性流程图。 图 1的方法由协同节点执行, 如图 1所示, 该方法 100包括:
S110, 获取不同制式的小区的状态信息, 该状态信息表示该不同制式的 小区的无线资源状态、 终端分布和业务情况中的至少一种;
S120, 根据该状态信息, 向该不同制式的小区的基站或者基站控制器发 送协同指示信息, 以使该基站或者该基站控制器根据该协同指示信息进行网 间协同操作。
在本发明实施例中, 为了优化多制式网络的资源利用效率, 通过协同节 点来统一协同多制式多层网间的无线资源和业务承载。协同节点获取不同制 式的小区的状态信息, 该状态信息表示该不同制式的小区的无线资源状态、 终端分布和业务情况中的至少一种, 根据该状态信息, 向该不同制式的小区 的基站或者基站控制器发送协同指示信息,从而使该基站或者该基站控制器 根据该协同指示信息进行网间协同操作。通过新增的协同节点来实时获取无 线网络的资源状态, 进行制式间的协同优化, 实现了制式间无线资源统一架 构协同优化, 因而能够最大化无线网络资源利用率。
因此, 本发明实施例的网间协同的方法, 根据不同制式的小区的状态信 息, 向该不同制式的小区的基站或者基站控制器发送协同指示信息, 使该基 站或者该基站控制器根据该协同指示信息进行网间协同操作, 可以最大化无 线网络资源利用率, 从而能够提升网络性能。

如图 2所示, 在 GSM、 UMTS和 LTE多制式网络系统中, 通过协同节 点 eCoordinator协同各小区。 协同节点和 GSM之间的接口 IeG, 承载 GSM 状态信息传递、对 GSM的协同指示信息;协同节点和 UMTS之间的接口 IeU, 承载 UMTS状态信息传递、 对 UMTS的协同指示信息; 协同节点和 LTE之 间的接口 IeL, 承载 LTE状态信息传递、 对 LTE的协同指示信息; 协同节点 之间的接口 lee, 承载对于区域边界的交互信息。 可选地, 这些接口可以是 新建的连接, 也可以利用现有连接。
在本发明实施例中, 该状态信息表示该不同制式的小区的无线资源状 态、 终端分布和业务情况中的至少一种, 例如, 无线资源的使用率、 用户优 先级、 业务类型、 终端类型、 用户服务情况、 负载信息、 接入成功率、 切换 成功率和掉话率等中的一种或多种。协同节点可以获取上述各信息中的一种 或多种, 并据此向基站或者基站控制器发送协同指示信息。
在 S110中, 协同节点获取不同制式的小区的状态信息。
协同节点获取各制式的小区的状态信息的方式有多种, 如图 3所示, 可 选地, S110包括:
5111 , 接收该基站或者该基站控制器周期性发送的该状态信息; 或者,
5112,接收该基站或者该基站控制器在无线资源状态发生变化时发送的 该状态信息; 或者,
5113, 向该基站或者该基站控制器发送请求该状态信息的请求消息, 接 收该基站或者该基站控制器响应该请求消息发送的该状态信息。
具体而言, 状态信息上报可以采用主动上报方式或者按请求上报方式。 在主动上报方式中,基站或者基站控制器周期性上报或者在无线资源状态发 生变化时上报状态信息给协同节点。 在按请求上报方式中, 协同节点先向基 站或者基站控制器发送请求状态信息的请求消息, 然后基站或者基站控制器 按照该请求消息上报状态信息给协同节点。例如,在图 2所示的系统中, BSC, RNC, eNodeB分别通过 IeG, IeU, IeL接口向协同节点 eCoordinator上报状 态信息。
在本发明实施例中, 如图 4所示, 可选地, 在 S110之前, 该方法 100 还包括:

在 S120中, 协同节点根据该状态信息, 向该不同制式的小区的基站或 者基站控制器发送协同指示信息, 以使该基站或者该基站控制器根据该协同 指示信息进行网间协同操作。
协同节点根据获取的各制式的小区的状态信息,分析区域内资源状态和 业务分布情况, 在无线资源使用达到预定门限时, 启动优化流程, 发送协同 指示信息给基站或者基站控制器, 以使其根据该协同指示信息进行网间协同 操作, 从而优化整个网络。

该协同指示信息包括邻区参数、 切换门限、 驻留参数、 功率参数和负载 门限中的至少一种。
应理解,本发明实施例中的第一预定门限和下文中出现的第二预定门限 表示预先设定的门限值, "第一" 和 "第二" 只是为了区别不同的门限值。
协同节点判断区域内无线资源使用率是否达到第一预定门限,如果达到 第一预定门限, 则启动参数优化, 下发优化的参数(例如, 上述各参数中的 一种或多种)给基站或者基站控制器, 使其根据下发的参数进行协同操作。 基站或者基站控制器接收到协同节点发送的参数后,根据这些参数进行协同 操作, 例如, 进行切换或调整功率等。 协同节点检测优化后的效果, 如果达 到目标, 例如, 无线资源使用率降到目标值,优化结束; 否则重新进行优化, 下发新的参数给基站或者基站控制器。 或者, 协同节点判断区域内两个小区 间切换成功率是否过低, 如果过低, 则启动切换优化, 通过调整切换参数下 发给基站或基站控制器, 并观察切换成功率是否达到要求, 如果没有满足则 继续调整, 如果满足要求, 则停止优化。
这样, 本发明实施例的网间协同的方法, 通过对不同制式的小区的无线 资源的集中优化,可以最大化无线网络资源利用率,从而能够提升网络性能。
可选地, 如图 5所示, S120包括:
5122, 若长期演进 LTE 小区的无线资源的使用率达到第二预定门限, 则向 eNodeB发送该协同指示信息。
该协同指示信息包括演进型基站 eNodeB物理小区标识 PCI、 eNodeB随 机接入信道 RACH序列、 邻区参数、 切换门限、 驻留参数、 功率参数和负载 门限中的至少一种。
协同节点可以对 LTE 系统内的各小区进行协同优化, 协同节点判断 eNodeB的无线资源使用率是否到达第二预定门限,如果达到第二预定门限, 则启动 LTE系统的参数优化, 下发优化的参数(例如, 上述各参数中的一种 或多种)给各 eNodeB , 使各 eNodeB进行协同操作。 eNodeB接收到协同节 点发送的参数后, 根据这些参数进行协同操作, 例如, 进行切换或调整功率 等。 协同节点检测优化后的效果, 如果达到目标, 例如, LTE网络的无线资 源使用率降到目标值, 优化结束; 否则重新进行优化, 下发新的参数给 eNodeB。 或者, 协同节点判断区域内 LTE干扰指标是否达到门限, 如果超 过门限,则启动干扰优化,给区域内的全部或者部分基站重新分配边缘频谱, 并观察是否达到干扰优化目标, 如果达到, 则停止优化, 否则继续。
这样,本发明实施例的网间协同的方法,通过对 LTE网络的无线资源的 集中优化, 可以最大化 LTE网络资源利用率, 从而能够提升网络性能。

S123, ^据该不同制式的小区的无线资源状态、 用户优先级和业务类型 中的至少一种, 向该基站或者该基站控制器发送业务承载调整指示, 以使该 不同制式的小区调整业务^ ^载。
协同节点可以根据不同制式的小区的状态信息, 进行业务承载调整。 协 同节点综合判断用户优先级、 业务类型和无线资源状态中的一种或多种, 下 发业务承载调整指示给基站或者基站控制器, 使其调整业务承载, 例如, 通 过切换等手段调整业务承载。 比如, 在网络忙时, 协同节点通过控制指令, 根据不同的数据包类型承载到不同层网络,如将小包数据业务从 UMTS调整 到 GSM承载, 大数据下载业务调整到 LTE, 快速移动的数据业务调整到 UMTS承载; 或者根据业务类型来调整承载, 如语音业务统一调整到 GSM, 视频业务调整到 LTE,上网调整到 UMTS等; 或者根据用户优先级来调整承 载, 如, 高优先级用户优先承载于 LTE, 中等优先级用户承载于 UMTS, 低 端用户承载于 GSM等等; 上述承载策略可以根据网络的实际情况和运营商 的资费策略来动态设置。 协同节点作为此策略的协调执行者, 核心优势在于 可以根据网络实时负载情况, 用户分布情况来动态调整。
可选地, 业务承载包括: 基于业务类型的承载选择、 基于服务质量
( Quality of Service, 筒称为 "QoS" ) 的承载选择、 基于负荷状态的承载选 择, 但本发明实施例对此并不限定。
可选地, 如图 5所示, S120包括:
S124, 根据 LTE 系统内各小区的负载信息, 向负载高于预定阈值的小 区的基站发送边缘用户使用的频率资源。
LTE 系统内各个小区的边缘用户都可能受到周边小区使用相同时频资 源用户较强烈的干扰, 影响用户吞吐率和体验。 为了保证这些用户能够获得 更好的体验, 可以协调相邻小区边缘用户使用不同的频率资源, 降低相互之 间的干扰。 协同节点可以根据各个小区的负载信息, 判断小区边缘用户是否 会出现较大的同频干扰, 在小区负载比较高 (即高于预定阈值)的时候, 通 过对于周边小区的联合分析, 为负载高的小区分配边缘用户使用的频率资 源, 保证相邻小区的边缘用户可以不互相干扰, 提升这些用户的体验。
可选地, 如图 5所示, S120包括:
5125 , 根据该不同制式的小区的负载情况, 向该基站或者该基站控制器 发送将部分频点小区或者部分制式的小区关断的指示信息, 或者, 向该基站 或者该基站控制器发送将关断的小区开启的指示信息。
随着移动宽带 (Mobile Broad Band, 筒称为 "MBB" )发展, 运营商逐 步建立了 LTE、 UMTS, GSM的多模多频网络。 在网络中存在夜晚等负载轻 的非忙时, 此时运营商可以选择保留一部分网络服务能力, 关断一部分网络 服务来节能。 在本发明实施例中, 协同节点可以通过获取网络中各个制式的 负载情况,在网络负荷低的时候选择某一制式中的部分频点小区或者某一制 式的小区进行关断, 节省能源。 在网络负载比较高的时候, 重新将关断的小 区投入使用。
可选地, 如图 5所示, S120包括:
5126, 根据 LTE 系统的宏基站和微基站的用户服务情况, 向该宏基站 或该 基站发送空子帧 ABS配置信息。
LTE 的宏微小区进行同频组网时, 可以利用增强小区间干扰协同 ( enhanced inter-cell interference coordination, 筒称为 "elCIC" )技术在系统 内分配空子帧 (Almost Blank Sub-Frame, 筒称为 "ABS" ) 资源给微基站的 边缘用户使用, 结合小站的覆盖范围扩展技术( Range Extension )使得微基 站可以服务更多用户,提升微基站边缘用户的体验。 ABS子帧宏基站不能使 用, 所以 ABS个数的配置需要根据微蜂窝边缘可服务用户数来判断, 达到 整体提升系统容量的目的。 在本发明实施例中, 协同节点可以根据宏、 微基 站的服务用户情况进行集中分析判断, 协同调整各个小区 ABS子帧的配置, 在提升微基站服务范围的同时, 整体提升系统容量。
可选地, 如图 5所示, S120包括:
5127, 根据 LTE系统内小区的 PCI沖突情况, 向 PCI沖突的小区的基 站发送不沖突的 PCI。
LTE系统内各个小区都分配了各自的 PCI标示,终端在连接状态时会测 量相邻小区的强度, 在测量发现有临近小区信号强度更好时上报该小区的 PCI及其信号强度, eNodeB根据 PCI判断是否进行相应的切换指示, 让终 端在更合适的小区进行服务。 在某些情况会出现由于 PCI规划不完善, UE 所处相邻小区中存在相同 PCI, 这是 eNodeB根据 UE上报的 PCI可能会选 择错误的邻区下发切换指示, 导致切换失败, 这种邻区中存在相同 PCI的情 况称为 PCI 沖突。 在本发明实施例中, 协同节点可以针对切换失败的小区 PCI进行 PCI沖突协调重分配, 由 eNodeB指示 UE针对指定 PCI进行小区 唯一索引 ( Cell Global ID, 筒称为 "CGI" ) 测量, 把 PCI沖突小区的 CGI 发送到协同节点, 协同节点进行小区的周边小区 PCI分配分析, 重新分配不 沖突的 PCI给该小区, 解决 PCI沖突问题, 保证切换成功率。
在本发明实施例中, 可选地, 该方法 100还包括:
根据 LTE邻区关系, 配置 GSM或者 UMTS邻区关系; 或者,
根据 GSM邻区关系, 配置 UMTS或者 LTE邻区关系; 或者,
根据 UMTS邻区关系, 配置 GSM或者 LTE邻区关系。
运营商往往都采用 LTE、 UMTS和 GSM共站点建设, 同时一个站点同 厂商建设 LTE、 UMTS, GSM的不同制式统一网络(SingleRAN )建网策略 已经成为一种趋势。 在这种情况下, 一个小区的各个制式邻区有着相同的地 理拓朴关系。在本发明实施例中,协同节点可以根据一个 LTE小区自动建立 的 LTE邻区关系快速进行拓朴分析, 配置该小区的 GSM、 UMTS邻区关系。 同时对一个 GSM 小区, 也可以根据站点拓朴关系分析, 快速配置相应的 UMTS, LTE邻区关系;对一个 UMTS小区,也可以根据站点拓朴关系分析, 快速配置相应的 GSM、 LTE邻区关系。 通过协同节点的集中拓朴分析, 提 高邻区配置效率。
本发明实施例的网间协同的方法, 根据不同制式的小区的状态信息, 按 照不同的业务特征灵活配置协同指示信息, 可以最大化无线网络资源利用 率, 提升网络性能和用户体验。
