技术领域technical field
实施例有关无线通信。更具体地说,实施例涉及无线通信系统内小区的自优化功能之间的协调。一些实施例涉及第三代合作伙伴项目、技术规范组服务和系统方面、电信管理、自组织网络(SON)策略网络资源模型(NRM)集成参考点(IRP)、信息服务(IS)3GPP TS32.522。Embodiments relate to wireless communications. More specifically, the embodiments relate to coordination between self-optimizing functions of cells within a wireless communication system. Some embodiments relate to 3rd Generation Partnership Project, Technical Specification Group Services and System Aspects, Telecommunications Management, Self-Organizing Network (SON) Policy Network Resource Model (NRM) Integration Reference Point (IRP), Information Services (IS) 3GPP TS32. 522.
背景技术Background technique
在无线网络的上下文中,自优化是如下的过程:分析增强节点B(eNodeB)的测量数据,并且然后调谐eNodeB的无线电和传输参数以便获得最优网络性能、覆盖范围和容量。自优化网络(SON)可实现各种SON功能,其例如包括载荷平衡、切换优化(HO)、覆盖范围和容量优化(CCO)、小区运转中断(outage)补偿(COC)和节能管理(ESM)。这些优化功能通过配置eNodeB的参数来改变小区的覆盖范围和容量。示例参数可包含下行链路传送的传送功率、天线倾斜度和方位参数。In the context of wireless networks, self-optimization is the process of analyzing enhanced Node B (eNodeB) measurement data, and then tuning the eNodeB's radio and transmission parameters in order to obtain optimal network performance, coverage and capacity. A Self-Optimizing Network (SON) may implement various SON functions including, for example, Load Balancing, Handover Optimization (HO), Coverage and Capacity Optimization (CCO), Cell Outage Compensation (COC), and Energy Saving Management (ESM) . These optimization functions change the coverage and capacity of the cell by configuring the parameters of the eNodeB. Example parameters may include transmit power, antenna tilt, and bearing parameters for downlink transmissions.
在当前第三代合作伙伴项目(3GPP)长期演进(LTE)系统中,SON功能可独立操作以改变一个或多个eNodeB的这些参数或其它参数。然而,当前3GPP LTE高级系统不支持SON功能之间的协调。因此,两个或更多SON功能可同时操作以改变同一eNodeB的同一配置参数。可能引起冲突,并且因此在受影响的eNodeB中可能出现不稳定性。In current 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) systems, the SON function can operate independently to change these or other parameters of one or more eNodeBs. However, current 3GPP LTE-Advanced systems do not support coordination between SON functions. Thus, two or more SON functions can operate simultaneously to change the same configuration parameter of the same eNodeB. Conflicts may arise and thus instability may arise in the affected eNodeB.
因而,存在对于在无线网络内协调SON功能操作的系统和方法的一般需要。Thus, there is a general need for systems and methods for coordinating the operation of SON functions within a wireless network.

具体实施方式Detailed ways
给出以下描述以使本领域技术人员能够创建和使用计算机系统配置以及相关方法和制品以便协调无线通信网络内由域管理器(DM)或增强节点B(eNodeB)执行的自优化网络(SON)功能。实现协调策略以确定eNodeB可实现不同SON功能的环境。在至少一个示例实施例中,这些协调策略将eNodeB的当前状态考虑进去了。这些协调策略还可基于eNodeB可改变到的期望SON功能的身份,或者与期望SON功能相关的其它输入。The following description is given to enable those skilled in the art to create and use computer system configurations and related methods and articles of manufacture for coordinating a self-optimizing network (SON) performed by a domain manager (DM) or enhanced node B (eNodeB) within a wireless communication network Function. A coordination strategy is implemented to determine the environment in which the eNodeB can implement different SON functions. In at least one example embodiment, these coordination strategies take into account the current state of the eNodeB. These coordination strategies may also be based on the identity of the desired SON function to which the eNodeB may change, or other inputs related to the desired SON function.
对实施例的各种修改对本领域技术人员而言将是显而易见的,并且本文定义的一般原则可在不脱离本发明范围的情况下应用于其它实施例和应用。此外,在以下描述中,为了说明目的,阐述了许多细节。然而,本领域技术人员将意识到,本发明的实施例可以在不使用这些特定细节的情况下实施。在其它情况下,众所周知的结构和过程未以框图形式示出,以免用不必要的细节模糊了对本发明实施例的描述。因而,本公开不打算局限于所示的实施例,而是符合与本文公开的原理和特征一致的最广范围。Various modifications to the embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the scope of the invention. Furthermore, in the following description, for purposes of explanation, numerous details are set forth. However, one skilled in the art will realize that embodiments of the present invention may be practiced without the use of these specific details. In other instances, well-known structures and processes are not shown in block diagram form in order not to obscure the description of embodiments of the invention with unnecessary detail. Thus, the present disclosure is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
图1例证了可在其中实现示例实施例的无线通信网络100的示例部分。在一个实施例中,无线通信网络100包括使用第三代合作伙伴项目(3GPP)长期演进(LTE)标准的演进通用地面无线电接入网(EUTRAN)。在一个实施例中,无线通信网络100包含第一eNodeB 101、第二eNodeB 102、第三eNodeB 103和第四eNodeB 104(也称为第一基站101、第二基站102、第三基站103)。第一eNodeB 101服务于某一地理区域小区1。类似地,第二eNodeB 102服务于地理区域小区2,第三eNodeB 103服务于地理区域小区3,并且第四eNodeB 104服务于地理区域小区4。1 illustrates an example portion of a wireless communication network 100 in which example embodiments may be implemented. In one embodiment, the wireless communication network 100 includes an Evolved Universal Terrestrial Radio Access Network (EUTRAN) using the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) standard. In one embodiment, the wireless communication network 100 includes a first eNodeB 101, a second eNodeB 102, a third eNodeB 103, and a fourth eNodeB 104 (also referred to as
要理解,无线通信网络100可包含多于4个eNodeB或少于4个eNodeB。还要理解,每个eNodeB都可具有多个相邻eNodeB。作为一个示例,eNodeB 103可具有6个或更多个相邻eNodeB。It is to be understood that the wireless communication network 100 may include more than 4 eNodeBs or less than 4 eNodeBs. It is also understood that each eNodeB may have multiple neighboring eNodeBs. As an example, eNodeB 103 may have 6 or more neighboring eNodeBs.
容量和覆盖范围优化(CCO)、小区运转中断补偿(COC)和节能管理(ESM)是可改变无线网络中一个或多个小区的覆盖范围或容量的SON功能。CCO SON功能力图最大化eNodeB的覆盖范围,同时最优化容量并确保小区间干扰被最小化。COCSON功能将eNodeB配置成补偿处于运转中断条件下的另一eNodeB。ESM功能将邻居eNodeB的覆盖范围扩展成覆盖配置成进入节能模式的eNodeB。如果这些SON功能之一改变了eNodeB,同时另一SON功能改变了同一eNodeB,则冲突可能发生。Capacity and Coverage Optimization (CCO), Cell Outage Compensation (COC), and Energy Saving Management (ESM) are SON functions that can alter the coverage or capacity of one or more cells in a wireless network. The CCO SON function seeks to maximize the coverage of the eNodeB while optimizing capacity and ensuring that inter-cell interference is minimized. The COCSON function configures an eNodeB to compensate for another eNodeB in an outage condition. The ESM function extends the coverage of neighbor eNodeBs to cover eNodeBs that are configured to enter power saving mode. A conflict may occur if one of these SON functions changes the eNodeB while another SON function changes the same eNodeB.
作为例证性示例,参考图1,如果小区1遭受服务运转中断,则COC SON功能将尝试通过重新配置可能候选小区的参数来补偿小区1的运转中断。例如,COC可尝试重新配置服务于小区2和3的eNodeB 102和103的传送功率、天线倾斜度和天线方位,使得eNodeB 102和103可补偿服务于小区1的eNodeB。然而,同时,ESM SON功能可操作在小区2上,以便当相邻小区4正在进入节能状态时补偿小区4的覆盖范围。因此,在此示例中,COC SON功能和ESMSON功能可尝试同时在小区2上操作。As an illustrative example, referring to Figure 1, if cell 1 suffers service outage, the COC SON function will attempt to compensate for cell 1 outage by reconfiguring the parameters of possible candidate cells. For example, the COC may attempt to reconfigure the transmit power, antenna tilt and antenna orientation of the
在这个例证性示例中,从检测到小区1运转中断的时间点,直到小区1已经由小区2和3补偿,除非在SON功能之间存在协调,否则COC SON功能和ESM SON功能可各尝试针对传送功率、天线倾斜度和天线方位配置eNodeB 102的不同设置。例如,COC可尝试向下倾斜eNodeB 102的天线,同时ESM尝试向上倾斜eNodeB 102的天线,从而导致eNodeB102不稳定性。In this illustrative example, from the point in time when cell 1 outage is detected until cell 1 has been compensated by cells 2 and 3, unless there is coordination between the SON functions, the COC SON function and the ESM SON function may each attempt to target The transmit power, antenna tilt and antenna orientation configure different settings of the
在示例实施例中,网络管理装置或网络管理器(NM)可合并SON协调机构,以协调网络100中eNodeB的覆盖范围和容量改变,并由此在SON功能之间提供冲突防止或冲突解决。网络管理装置可包含接口,该接口接收改变网络100中eNodeB的覆盖范围和容量的请求。这个接口还可向eNodeB传送询问以获得该eNodeB的SON协调状态。网络管理装置还可包含一个或多个处理器。这些处理器可执行基于协调策略和SON协调状态来确定是准许该请求还是拒绝该请求的算法。基于协调策略和SON协调状态,网络管理装置根据协调策略的覆盖范围和容量要求来协调网络100中eNodeB的覆盖范围和容量改变,同时根据协调策略来最小化小区间干扰和能量使用。In an example embodiment, a network management device or network manager (NM) may incorporate a SON coordination mechanism to coordinate coverage and capacity changes of eNodeBs in network 100 and thereby provide conflict prevention or conflict resolution between SON functions. The network management device may include an interface that receives requests to change the coverage and capacity of eNodeBs in the network 100 . This interface may also transmit queries to the eNodeB to obtain the eNodeB's SON coordination status. The network management device may also include one or more processors. These processors may execute algorithms that determine whether to grant or deny the request based on the coordination policy and the SON coordination status. Based on the coordination strategy and the SON coordination state, the network management apparatus coordinates coverage and capacity changes of the eNodeBs in the network 100 according to the coverage and capacity requirements of the coordination strategy, while minimizing inter-cell interference and energy usage according to the coordination strategy.
根据示例实施例,支持SON协调的NM读以及写网络100中eNodeB的SON协调状态属性、sonCoordinationState的值。表1示出了该属性的值:According to an example embodiment, the NM that supports SON coordination reads and writes the value of the SON coordination state attribute, sonCoordinationState, of the eNodeBs in the network 100 . Table 1 shows the value of this attribute:
表1:sonCoordinationState属性的值Table 1: Values of the sonCoordinationState property
图2例证了根据至少一个示例实施例用于提供SON协调功能的系统200的架构。如图2所示,标准接口Itf-N位于网络管理器(NM)与域管理器(DM)之间。Itf-N可用于传送在网络中生成的性能测量结果数据,并用于传送性能警告或通知。Figure 2 illustrates the architecture of a
诸如eNodeB 201、202和203等网络单元提供数据以支持网络性能评估。这种数据可包含服务质量(QoS)测量结果、网络配置验证或其它参数。单元管理器(EM)206、207通过例如管理性能测量收集过程并生成性能测量结果来管理测量结果数据的产生。Network elements such as
EM 206可驻留在DM中。DM的示例任务包含配置eNodeB、故障管理和性能监视。性能监视可包括诸如从eNodeB 203、204和205接收性能数据等任务。
eNode B203和204可通过DM 202与NM 201通信。备选地,eNodeB 203可实现它自己的EM 207以直接与NM 201通信。在一些实施例中,NM和这些SON功能可根据3GPP TS 32.522操作,但这不是必要条件。The
图3例证了示例框图,该示例框图示出根据示例实施例可适合于用作eNodeB 101、102、103、104、203、204和205中任一个eNodeB的eNodeB 301的细节,不过其它配置可能也是合适的。eNodeB 301可包含处理器300、存储器302、收发器304、指令306和其它组件(未示出)。eNodeB 101、102、103、104、203、204和205在硬件、固件、软件、配置和/或操作参数方面可彼此类似。Figure 3 illustrates an example block diagram showing details of an
处理器300包括一个或多个中央处理单元(CPU)、图形处理单元(GPU)或二者。处理器300为eNodeB提供处理和控制功能性。存储器302包括一个或多个配置成存储用于eNodeB的指令和数据的暂态和静态存储器单元。收发器304包括一个或多个收发器,所述一个或多个收发器包含多输入和多输出(MIMO)天线以支持MIMO通信。收发器304接收上行链路传送,并传送下行链路传送,尤其是与用户设备(UE)。在一些实施例中,收发器304传送改变eNodeB的覆盖范围和容量状态的请求。在一些实施例中,响应于该请求,收发器接收指示已经准许还是拒绝改变覆盖范围状态的请求的许可通知。在一些实施例中,基于是否已经准许许可,处理器300将SON协调状态存储在相关联存储器302中,并改变eNodeB的覆盖范围和容量状态。
指令306包括在计算装置(或机器)上执行的一个或多个指令集或软件以使这种计算装置(或机器)执行本文讨论的任何方法。指令306(也称为计算机可执行指令或机器可执行指令)在由eNodeB执行期间可完全或至少部分驻留在处理器300内和/或存储器302内。处理器300和存储器302也包括机器可读介质。
图4例证了示例机器400的框图,在示例机器400上可执行本文讨论的网络管理器(NM)所执行操作中的任何一个或多个操作。在备选实施例中,机器400可作为独立装置操作,或可连接(例如连网)到其它机器。在连网的部署中,机器400在服务器-客户端网络环境中可在服务器机器、客户端机器或二者的容量中操作。在一个示例中,机器400可充当对等(P2P)(或其它分布式)网络环境中的对等机器。4 illustrates a block diagram of an example machine 400 on which any one or more of the operations performed by the network manager (NM) discussed herein may be performed. In alternative embodiments, machine 400 may operate as a stand-alone device, or may be connected (eg, networked) to other machines. In a networked deployment, machine 400 may operate in the capacity of a server machine, a client machine, or both in a server-client network environment. In one example, machine 400 may act as a peer-to-peer machine in a peer-to-peer (P2P) (or other distributed) network environment.
机器(例如计算机系统)400可包含硬件处理器402(例如中央处理单元(CPU)、图形处理单元(GPU)、硬件处理器核或它们的任何组合)、主存储器404和静态存储器406,其中的一些或所有可经由互连链路(interlink)(例如总线)408彼此通信。机器400还可包含显示单元410、字母数字输入装置412(例如键盘)和用户接口(UI)导航装置414(例如鼠标)。在一个示例中,显示单元410、输入装置412和UI导航装置414可以是触摸屏显示器。机器400还可包含存储装置(例如驱动器单元)416、信号发生装置418(例如扬声器)、网络接口装置420和一个或多个传感器421(诸如全球定位系统(GPS)传感器、罗盘仪、加速计或其它传感器)。机器400可包含输出控制器428,诸如串行(例如通用串行总线(USB)、并行或其它有线或无线(例如红外(IR))连接,以通信或控制一个或多个外围装置(例如打印机、读卡器等)。Machine (eg, computer system) 400 may include hardware processor 402 (eg, central processing unit (CPU), graphics processing unit (GPU), hardware processor core, or any combination thereof),
存储装置416可包含机器可读介质422,机器可读介质422上存储了通过本文描述的技术或功能中的任何一种或多种来实施或利用的一组或多组数据结构或一个或多个指令集424(例如软件)。指令424也可在由机器400执行期间完全或至少部分驻留在主存储器404内、静态存储器406内或硬件处理器402内。在一个示例中,硬件处理器402、主存储器404、静态存储器406或存储装置416的一个组合或任何组合可构成机器可读介质。
虽然机器可读介质422被例证为单个介质,但是术语“机器可读介质”可包含设置成存储一个或多个指令424的单个介质或多个介质(例如集中式数据库或分布式数据库和/或相关联的高速缓存和服务器)。Although machine-
还可利用若干传输协议(例如帧中继、因特网协议(IP)、传送控制协议(TCP)、用户数据报协议(UDP)、超文本传输协议(HTTP)等)中的任一个、经由网络接口装置420、使用传送介质、通过通信网络426传送或接收指令424。术语“传送介质”将被视为包含能够存储、编码或承载由机器400执行的指令的任何无形介质,并且包含数字通信信号或模拟通信信号或者便于这种软件通信的其它无形介质。根据下面描述的示例实施例,指令424可实现用于SON协调机构的算法。may also utilize any of several transport protocols (eg, Frame Relay, Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), Hypertext Transfer Protocol (HTTP), etc.) via a network interface The
再次参考图2,用于根据示例实施例实现SON协调的SON协调功能驻留在Itf-N上方,并且通过指令424在NM 201的处理器402上实现。然而,将理解到,SON协调功能可驻留在Itf-N下方。例如,SON协调功能可驻留在DM 202中以便协调由DM 202管理的eNodeB 203和204或其它eNodeB(未示出)。Referring again to FIG. 2 , the SON coordination function for implementing SON coordination according to an example embodiment resides above Itf-N and is implemented by
图5例证了信号流程图,该信号流程图描绘根据示例实施例在EM与NM 201之间经过以便实现SON协调功能以防止ESM、COC和CCO SON功能之间发生冲突的信号。Figure 5 illustrates a signal flow diagram depicting the signals passing between the EM and
在信号1中,SON协调实体接收改变网络的eNodeB的覆盖范围和容量的请求。在示例实施例中,SON协调实体是NM 201。可从DM 202接收该请求。备选地,如果eNodeB包含嵌入式EM,则可直接从eNodeB接收该请求。In signal 1, the SON coordination entity receives a request to change the coverage and capacity of the eNodeBs of the network. In an example embodiment, the SON coordination entity is
在消息2中,NM询问DM或eNodeB以获得SON协调状态。SON协调状态指示小区在支持CCO、COC和ESM功能方面的行为,并且可包含如下值之一:EsmCompensating、EsmEnergySaving、CocCompensating、CocOutage、CcoUpdating和None。In message 2, the NM asks the DM or the eNodeB to obtain the SON coordination status. The SON coordination state indicates the behavior of the cell in supporting CCO, COC and ESM functions and may contain one of the following values: EsmCompensating, EsmEnergySaving, CocCompensating, CocOutage, CcoUpdating and None.
NM 201然后基于SON协调策略和SON协调状态来确定是准许该请求还是拒绝该请求。下面描述SON协调策略。在示例实施例中,SON协调策略基于来自SON功能的一个或多个输入、由网络运营商指配给SON功能的优先权等级和网络运营商策略。The
如果eNodeB处于EsmCompensating SON协调状态,并且NM 201得到关于eNodeB所服务的小区已经运转中断的通知,则SON协调策略根据示例实施例规定:NM 201通知ESM功能找到另一小区以补偿节能小区。如果ESM功能不能够找到另一小区,则ESM功能要去激活由eNodeB补偿的小区上的节能。NM 201然后将eNodeB的SON协调状态改变成CocOutage。If the eNodeB is in the EsmCompensating SON coordination state, and the
如果NM201接收到要求eNodeB补偿处于运转中断的相邻小区的COC请求,同时eNodeB处于EsmCompensating SON协调状态,则SON协调策略根据示例实施例规定:NM 201基于网络运营商策略来确定COC和ESM的优先权。如果ESM SON功能具有更高优先权,则COC请求遭到拒绝。如果COC SON功能具有更高优先权,则NM 201通知ESM SON功能找到另一个相邻小区以补偿节能小区。如果ESM SON功能不能够找到另一个小区以补偿节能小区,则NM201通知ESM SON功能去激活由eNodeB补偿的小区上的节能。NM 201然后接受COC请求并且NM 201将eNodeB的SON协调状态改变成None。If the
如果eNodeB处于EsmEnergySaving状态,并且NM 201接收补偿处于运转中断的相邻小区的COC请求,则SON协调策略根据示例实施例规定:NM 201应该通知ESM SON功能要求eNodeB退出节能。如果ESM SON功能不能够请求eNodeB退出节能,则NM 201拒绝该COC请求。如果ESM SON功能能够请求eNodeB退出节能,则NM 201接受该COC请求并将SON协调状态改变成None。If the eNodeB is in the EsmEnergySaving state and the
如果eNodeB处于CocCompensating状态,并且NM 201得到关于eNodeB正在遭受运转中断条件的通知,则SON协调策略规定:NM 201通知COC SON功能找到一个或多个相邻eNodeB以补偿作出请求的eNodeB和由该作出请求的eNodeB之前补偿过的小区。NM 201进一步将作出请求的eNodeB的SON协调状态改变成CocOutage。If the eNodeB is in the CocCompensating state and the
如果eNodeB处于CocOutage状态,则NM 201拒绝所有请求。如果eNodeB处于CcoUpdating状态,则NM 201推迟所有ESM和COC请求,直到SON协调状态改变成None。如果eNodeB处于None状态,则NM 201接受来自CCO、COC或ESM SON功能的任何请求。If the eNodeB is in the CocOutage state, the
如果eNodeB处于EsmCompensating状态、EsmEnergySaving状态或CocCompensating状态,并且NM 201接收到改变eNodeB的覆盖范围和容量的CCO请求,则NM201基于网络运营商策略来确定是否接受该请求。如果要接受CCO请求,则NM 201将SON协调状态改变成CcoUpdating。If the eNodeB is in the EsmCompensating state, EsmEnergySaving state or CocCompensating state, and the
此外,NM 201不允许在SON协调策略中未规定的任何请求,或拒绝在SON协调策略中未规定的任何请求。Furthermore, the
NM 201可使用一段或多段附加数据来帮助防止SON功能之间的冲突。一个或多个参数可以是来自ESM SON功能、CCO SON功能或COC SON功能中一个或多个功能的输入。这些输入可包含正在请求许可以修改eNodeB配置参数的SON功能的标识信息。该身份可包含关于SON功能的供应商、发行号、版本等信息。这些输入还可包含任何新更新的eNodeB配置参数应该由其它或相同SON功能保持不变的持续时间。更进一步,这些输入可包含作为配置改变理由的SON目标。例如,关键性能指示符(KPI)可由近来已经经历配置参数改变的eNodeB来报告。这个KPI与SON目标值相比较以验证之前的改变是否已经在KPI方面取得了改进。如果该评估指示未取得充分改进,则这可指示应该至少针对报告的eNodeB执行进一步优化和配置改变。这些输入也可包含有关参数改变对网络中其它对象的可能影响的任何信息,即参数改变的影响区域。One or more pieces of additional data may be used by
为了防止冲突,NM 201可依赖于另外信息,诸如参数改变对关键性能指示符(KPI)的可能影响。NM 201还可依赖于有关eNodeB当前状态、网络中某些被管理对象的状态、SON功能的优先权和SON协调策略的信息。To prevent conflicts, the
基于上面描述的SON协调策略,NM 201返回消息3(拒绝该请求)或消息4(准许该请求)。如果该决定是拒绝请求的决定,则不发生进一步处理,并且不进行配置改变。在另一方面,如果该决定是准许该请求的决定,则eNodeB或DM改变覆盖范围和容量,并在消息5中,通知NM 201覆盖范围和容量改变已经完成。eNodeB或DM还可传送有关参数改变成功或失败的信息,或者参数改变之前和之后的参数值。Based on the SON coordination policy described above, the
在eNodeB上已经完成SON功能之后,SON协调状态应该改变成EsmCompensating、EsmEnergySaving或CocCompensating之一。例如,在ESM激活小区以起到节能补偿作用之后,这种小区的SON协调状态应改变成EsmCompensating。在消息6中,NM 201通知eNodeB或DMeNodeB的SON协调状态应该改变,并且DM或eNodeB将新SON协调状态存储在存储器302中。After the SON function has been completed on the eNodeB, the SON coordination state should change to one of EsmCompensating, EsmEnergySaving or CocCompensating. For example, after an ESM activates a cell for energy saving compensation, the SON coordination state of such a cell should be changed to EsmCompensating. In message 6, the
在其它示例实施例中,作为对如下的附加或代替:由SON功能拒绝或准许请求,NM可用特定值配置至少一个eNodeB的特定参数。在示例实施例中,NM可防止参数由一个或多个SON功能在该参数已经被另一个SON功能改变之后的特定时间内改变。NM还可通知SON功能可影响性能指示符计算的状态改变。In other example embodiments, in addition to or in lieu of rejecting or granting the request by the SON function, the NM may configure specific parameters of at least one eNodeB with specific values. In an example embodiment, the NM may prevent a parameter from being changed by one or more SON functions within a certain time after the parameter has been changed by another SON function. The NM may also notify the SON function of state changes that may affect the performance indicator calculation.
在其它示例实施例中,NM 201检测SON功能之间的冲突并主动解决SON功能之间的冲突。NM 201可与上述冲突防止过程并行并且除了上述冲突防止过程之外还实现这种冲突解决。为了检测冲突,在NM 201上实现的SON协调功能分析诸如例如关键性能指示符(KPI)等数据、指示SON功能是否满足它们目标的测量结果以及eNodeB配置参数随时间的不可接受的振荡或变化。这些测量结果或数据中的任一个的异常都可指示SON功能正在彼此冲突地操作。In other example embodiments,
为了解决检测到的冲突,NM 201可启用、禁用或中止SON功能。SON配置功能可修改某些SON功能的配置,或者SON配置功能可修改eNodeB的配置参数。To resolve detected conflicts,
将认识到,为了清楚性目的,以上描述参考不同功能单元或处理器来描述一些实施例。然而,将明白,可使用功能性在不同功能单元、处理器或域之间的任何适当分布,而不脱离本发明的实施例。例如,例证为由分开的处理器或控制器执行的功能性可由同一处理器或控制器执行。因此,提及特定功能单元仅被看作提及用于提供所描述功能性的适当构件,而不是指示严格的逻辑或物理结构或组织。It will be appreciated that, for purposes of clarity, the above description describes some embodiments with reference to different functional units or processors. It will be appreciated, however, that any suitable distribution of functionality between different functional units, processors or domains may be used without departing from the embodiments of the invention. For example, functionality illustrated to be performed by separate processors or controllers may be performed by the same processor or controller. Thus, references to particular functional units are seen only as references to appropriate means for providing the described functionality, rather than as an indication of a strict logical or physical structure or organization.
尽管已经结合一些实施例描述了本发明,但不打算局限于本文阐述的特定形式。本领域技术人员将认识到,根据本发明可组合所描述实施例的各种特征。而且,将认识到,本领域技术人员可在不脱离本发明精神和范围的情况下进行各种修改和改变。Although the present invention has been described in connection with some embodiments, it is not intended to be limited to the specific form set forth herein.

提供本公开的摘要以快速明确技术公开的性质。它是在如下理解下被提出的:它不会用于解释或限制权利要求书的范围或含义。此外,在前面的具体实施方式中,可以看到,为了精简本公开的目的,各种特征一起组合在单个实施例中。公开的这个方法不要解释为反映如下意图:要求权利的实施例需要的特征比在每个权利要求中明确阐述的更多。而是,如以下权利要求书反映的那样,发明的主题在于少于公开的单个实施例的所有特征。因而,以下权利要求书由此合并到具体实施方式中,其中每个权利要求都代表它自己作为单独的实施例。The Abstract of the Disclosure is provided to quickly clarify the nature of the technical disclosure. It is presented with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. Furthermore, in the foregoing Detailed Description, it can be seen that various features are grouped together in a single embodiment for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus, the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separate embodiment.
