O-RAN针对节能特性,识别了相应子用例,其中之一为支持小区关断。用例考虑在Near-RT RIC部署人工智能(Artificial Intelligence,AI)/机器学习(Machine Learning,ML)模型,完成推理得到输出,并通过E2接口对基站实现节能相关的配置优化,提升系统的能效。尽管目前E2SM-RC(E2Service Model RAN Control)中主要针对终端(User Equipment,UE)级别控制,最新版规范已引入了基于UE 组(Group)的控制,其中UE Group可定义为特定小区或小区组,进而实现小区级别控制。然而,E2SM-RC规范中尚未支持节能特性的实现,这将会导致Near-RT RIC无法智能控制无线系统降低能耗。

具体实施方式
目前O-RAN正在讨论节能特性的引入,O-RAN针对节能特性,识别了相应子用例,其中之一为支持小区关断。用例考虑在Near-RT RIC部署AI/ML模型,完成推理得到输出,并通过E2接口对基站实现节能相关的配置优化,提升系统的能效。当负载较低时,可通过关断一个或多个小区来实现节能。为了不影响用户体验,需要关断的小区上服务的用户,需要卸载到新的目标小区上,再完成关断。
通过E2SM(E2Service Model)系列规范具体定义E2节点无线接入网功能(RAN Function)的实现方式,包含报告(Report)、插入(Insert)、控制(Control)和策略(Policy)服务。尽管目前E2SM-RC中主要针对UE级别控制,最新版规范已引入了基于小区组的控制,进而实现小区级别控制。然而,E2SM-RC规范中尚未支持节能特性的实现。
为使本公开实施例的目的、技术方案和优点更加清楚,下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在 没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
图1是本公开实施例提供的节能控制方法的流程示意图之一,如图1所示,本公开实施例提供一种节能控制方法,其执行主体可以为近实时RIC。该方法包括:
步骤101、向E2节点发送第一消息;所述第一消息包含第一节能控制策略信息,所述第一节能控制策略信息用于控制E2节点的小区进入节能模式或者节能补偿模式。
具体地,Near-RT RIC发送RIC控制请求(RIC Control Request)消息,控制E2节点连接的小区进入节能模式或者节能补偿模式,并设定节能模式持续时间;同时,可对节能补偿小区提供功率调整参数。E2节点可在RIC控制确认(RIC Control Acknowledge)消息中反馈节能模式配置情况。小区在持续时间后退出节能或节能补偿模式,E2节点根据小区情况通过包含报告的RIC指示(RIC Indication)消息上报小区激活状态。或者Near-RT RIC发送RIC控制请求消息,控制小区进入节能模式或者节能补偿模式。E2节点可在RIC控制确认中反馈节能模式配置情况。Near-RT RIC根据E2节点后续上报的小区信息,发送RIC控制请求信息,直接控制小区退出节能模式或者节能补偿模式。
其中,Near-RT RIC为近实时RIC。节能小区是指进入节能模式的小区。补偿小区是指进入节能补偿模式的小区。节能模式是指小区进入节能模式后,将关断该小区或者限制物理资源的使用以达到节能目的。节能补偿模式是指为应对某些小区进入节能模式,处于节能补偿模式下的小区仍保持运作,接管节能小区原本的覆盖区域,承接节能小区的流量。
例如,Near-RT RIC根据E2节点上报的信息分析数据,并执行AI/ML模型推理,根据优化目标或者策略,决定发起对E2节点的小 区关断的智能控制,发送RIC控制请求消息,其中包括:指定一些原始小区进入节能模式、节能模式持续时长,指定候选小区进入节能补偿模式、持续时长、补偿小区的功率调整以增加覆盖等。
本公开实施例提供的节能控制方法,通过定义针对智能小区关断的智能节能控制的实现方式、流程和消息增强方法,弥补了当前E2接口相关规范无法支持节能特性的缺失,支持Near-RT RIC在RAN侧实现节能的灵活配置,能够智能控制无线系统降低能耗。
在一些实施例中,所述第一节能控制策略信息包括以下信息中的一种或多种:
小区标识;
小区组标识;
进入节能模式指示;
进入节能补偿模式指示;
节能模式持续时长;
节能补偿模式持续时长;
补偿模式发射功率绝对值;
补偿模式发射功率相对值。
具体地,当E2节点接收到包含该控制动作的控制消息时,将按照控制指令将需要进入节能模式的小区的业务转移到节能补偿小区,将原本连接到节能小区的UE切换到补偿小区。并且为保障补偿小区能够应对节能小区关断后,满足此前的覆盖,可考虑配置发射功率以增加补偿小区的覆盖范围。其中,补偿模式发射功率绝对值是指当前补偿模式发射功率的值。补偿模式发射功率相对值是指当前补偿模式发射功率的值与前一时间点补偿模式发射功率的值的差值。
本公开实施例提供的节能控制方法,通过增加Near-RT RIC发送给E2节点的RIC控制请求消息,使E2节点按照控制指令控制相应小区进入节能模式或者节能补偿模式,并能将需要进入节能模式的小 区的业务转移到节能补偿小区,弥补了当前E2接口相关规范无法支持节能特性的缺失,支持Near-RT RIC在RAN侧实现节能的灵活配置,能够智能控制无线系统降低能耗。
在一些实施例中,所述方法还包括:
获取E2节点发送的小区节能控制执行结果信息。
具体地,当E2节点接收到RIC控制请求消息时,将按照小区关断的控制指令进行小区的配置,激活小区节能模式,并对节能小区和补偿小区进行相应配置。E2节点将根据控制指令的执行情况向Near-RT RIC反馈小区智能关断的执行结果,使用RIC控制确认消息携带该控制结果(Control Outcome)。
本公开实施例提供的节能控制方法,通过定义针对智能小区关断的智能节能控制的实现方式、流程和消息增强方法,弥补了当前E2接口相关规范无法支持节能特性的缺失,支持Near-RT RIC在RAN侧实现节能的灵活配置,能够智能控制无线系统降低能耗。
在一些实施例中,所述小区节能控制执行结果信息包括以下信息中的一种或多种:
小区标识;
小区组标识;

小区节能补偿模式是否激活的结果反馈。
具体地,在结果反馈中增加节能反馈的参数,可针对节能小区是否进入节能模式以及补偿小区是否进入节能补偿模式联合反馈。其中,小区标识用来标识需要进行节能控制的小区。小区组标识用来标识需要进行节能控制的小区组。
例如,反馈小区节能模式是否激活的结果。
再例如,反馈小区节能补偿模式是否激活的结果。
本公开实施例提供的节能控制方法,通过在结果反馈中增加节能 反馈的参数,增加了适用性,弥补了当前E2接口相关规范无法支持节能特性的缺失,支持Near-RT RIC在RAN侧实现节能的灵活配置,能够智能控制无线系统降低能耗。
在一些实施例中,所述方法还包括:
获取E2节点发送的小区激活状态的反馈信息。
具体地,当E2节点根据节能控制动作中的具体参数配置节能小区和节能模式持续时长后,相应小区将在持续时长后退出节能状态。E2节点可根据负载情况,决定该小区是否被重新激活。由于小区退出节能状态,满足小区节能状态改变和到达持续时长的触发条件,E2节点将小区激活状态的信息反馈给Near-RT RIC。
本公开实施例提供的节能控制方法,通过增加触发条件触发E2节点向Near-RT RIC反馈小区激活状态,弥补了当前E2接口相关规范无法支持节能特性的缺失,支持Near-RT RIC在RAN侧实现节能的灵活配置,能够智能控制无线系统降低能耗。
在一些实施例中,所述方法还包括:
向E2节点发送第二消息;所述第二消息用于订阅在小区节能模式发生改变的情况下E2节点上报的小区激活状态的反馈信息。
具体地,Near-RT RIC和E2节点之间建立包含报告的RIC订阅(RIC Subscription),若E2节点执行配置节能小区和节能模式持续时长后,相应小区在持续时长后退出节能状态或节能补偿状态,E2节点可决定节能小区是否被重新激活,并通过报告将小区是否激活的信息反馈给Near-RT RIC。
本公开实施例提供的节能控制方法,通过在Near-RT RIC和E2节点之间建立RIC订阅,Near-RT RIC接收E2节点发送的小区激活状态的反馈信息,弥补了当前E2接口相关规范无法支持节能特性的缺失,支持Near-RT RIC在RAN侧实现节能的灵活配置,能够智能控制无线系统降低能耗。
在一些实施例中,向E2节点发送第一消息之后,还包括:
获取E2节点发送的与小区节能相关的信息;
基于所述与小区节能相关的信息,得到第二节能控制策略信息;
向E2节点发送第三消息;所述第三消息包含所述第二节能控制策略信息,所述第二节能控制策略信息用于控制E2节点的小区退出节能模式或者节能补偿模式。
具体地,Near-RT RIC根据后续E2节点上报的节能相关信息,决定指示E2节点的小区退出节能状态,将再次发送RIC控制请求消息,指示相关小区退出节能状态。E2节点接收到RIC控制请求消息,将按照控制动作退出小区节能模式,并向Near-RT RIC反馈节能控制的结果。
本公开实施例提供的节能控制方法,通过定义针对智能小区关断的智能节能控制的实现方式、流程和消息增强方法,弥补了当前E2接口相关规范无法支持节能特性的缺失,支持Near-RT RIC在RAN侧实现节能的灵活配置,能够智能控制无线系统降低能耗。
在一些实施例中,所述第二节能控制策略信息包括以下信息中的一种或多种:
小区标识;
小区组标识;
退出节能模式指示;
退出节能补偿模式指示。
具体地,Near-RT RIC根据后续E2节点上报的节能相关信息,决定指示E2节点的小区退出节能状态,将再次发送RIC控制请求消息,指示相关小区退出节能状态。
例如,指示节能小区退出节能模式。
再例如,指示节能补偿小区退出节能补偿模式。
本公开实施例提供的节能控制方法,通过增加指示相关小区退出 节能状态的信息,保障相关小区能够退出及时节能状态,弥补了当前E2接口相关规范无法支持节能特性的缺失,支持Near-RT RIC在RAN侧实现节能的灵活配置,能够智能控制无线系统降低能耗。
图2是本公开实施例提供的节能控制方法的接口节能控制流程示意图之一,如图2所示,支持小区关断的节能控制方案和流程如下:
步骤1:Near-RT RIC和E2节点之间建立包含报告的RIC订阅,收集小区信息、节能相关的配置、性能指标和测量报告等信息。E2节点将根据订阅的要求,发送RIC指示消息,包含节能相关的上报信息,例如小区的负载相关信息、小区的流量信息、小区的能效或者小区的功耗相关测量报告。
步骤2:Near-RT RIC根据E2节点上报的信息分析数据,并执行AI/ML模型推理,根据优化目标或者策略,决定发起对E2节点的小区关断的智能控制,发送RIC控制请求消息,其中包括:指定一些原始小区进入节能模式、节能模式持续时长,指定候选小区进入节能补偿模式、持续时长、补偿小区的功率调整以增加覆盖等。
步骤3:当E2节点接收到RIC控制请求消息时,将按照小区关断的控制指令进行小区的配置,激活小区节能模式,并对节能小区和补偿小区进行相应配置。E2节点将根据控制指令的执行情况向Near-RT RIC反馈小区智能关断的执行结果,使用RIC控制确认消息携带该结果反馈。
步骤4:若E2节点执行配置节能小区和节能模式持续时长后,相应小区在持续时长后退出节能状态或节能补偿状态,E2节点可决定节能小区是否被重新激活,并通过报告将小区是否激活的信息反馈给Near-RT RIC。
图3是本公开实施例提供的节能控制方法的接口节能控制流程示意图之二,如图3所示,支持小区关断的节能控制方案和流程如下:
步骤1:Near-RT RIC和E2节点之间建立包含报告的RIC订阅, 收集小区信息、节能相关的配置、性能指标和测量报告等信息。E2节点将根据订阅的要求,发送RIC指示消息,包含节能相关的上报信息,例如小区的负载相关信息、小区的流量信息、小区的能效或者小区的功耗相关测量报告。
步骤2:Near-RT RIC根据E2节点上报的信息分析数据,并执行AI/ML模型推理,根据优化目标或者策略,决定发起对E2节点的小区关断的智能控制,发送RIC控制请求消息,其中包括:指定一些原始小区进入节能模式、指定候选小区进入节能补偿模式、补偿小区的功率调整以增加覆盖等。
步骤3:当E2节点接收到RIC控制请求消息时,将按照小区关断的控制指令进行小区的配置,激活小区节能模式,并对节能小区和补偿小区进行相应配置。E2节点将根据控制指令的执行情况向Near-RT RIC反馈小区智能关断的执行结果,使用RIC控制确认消息携带该结果反馈。
步骤4:Near-RT RIC根据后续E2节点上报的节能相关信息,决定指示E2节点的小区退出节能状态,将再次发送RIC控制请求消息,指示相关小区退出节能状态。
步骤5:E2节点接收到RIC控制请求消息,将按照控制动作退出小区节能模式,并向Near-RT RIC反馈节能控制的结果。
下面以几个具体的例子,对上述实施例中的方法进行进一步说明。
例一:在E2SM-RC中支持小区关断的节能特性。
图4是本公开实施例提供的基于E2SM-RC的控制流程示意图,如图4所示,本公开实施例提供一种节能控制方法包括以下步骤:
步骤1:Near-RT RIC和E2节点之间建立报告相关的RIC订阅,收集配置、性能指标和测量报告等信息。
步骤2:E2节点根据订阅的要求,发送RIC指示消息,包含节能相关的上报信息,例如小区的负载相关信息、小区的流量信息、小 区的能效或者小区的功耗相关测量报告。
步骤3:Near-RT RIC根据E2节点上报的信息分析数据,并执行AI/ML模型推理,根据优化目标或者策略,决定发起对E2节点的节能控制。
步骤4:Near-RT RIC发送RIC控制请求消息,其中RAN功能ID指示为E2SM-RC,包含了新定义的控制样式(Control Style)X及相应的控制动作(Control Actions)。
步骤5:E2节点根据Near-RT RIC指定的控制命令,执行小区关断的配置。E2节点执行该动作可进一步反馈RIC控制确认消息给Near-RT RIC。
上述步骤中,部分消息的增强设计包括以下几个方面:
(1)RIC控制请求消息的增强设计。
E2SM-RC目前支持针对单UE的智能控制,关于UE组控制目前规范中已支持。在RIC控制标题(Control Header)中设定UE组为节点级别(Node level)或者小区级别(Cell level)的过滤条件,可实现对节点或小区级别的控制。
为使得图2步骤2和图3步骤2中的RIC控制请求消息可支持小区关断的节能控制,需要在E2SM-RC中定义RIC控制消息IE中包含的具体控制内容。在现有的E2SM-RC控制服务样式(Control Service Style)中增加新的控制样式X用于配置节能相关参数,如下表所示:
表1控制服务样式类型列表(Control Service Style Types list)
该控制样式X下包含控制动作1:小区节能(ES)模式控制,后续如有需要也可扩展。
表2控制样式X节能控制支持的控制动作
控制动作1中小区节能模式开关控制相关的控制参数如下:
表3控制动作1的RAN参数
上述控制样式X和控制动作1将包含在RIC控制请求消息的RIC控制标题IE中,而表3所示该控制动作具体的RAN参数则包含在RIC控制消息IE中。
当E2节点接收到包含该控制动作的控制消息时,将按照控制指令将需要进入节能模式的小区的业务转移到节能补偿小区,将原本连接到节能小区的UE切换到补偿小区。或由Near-RT RIC在指示控制动作1之前,使用控制样式3连接模式移动性控制对相关UE进行业务转移。
为保障补偿小区能够应对节能小区关断后,满足此前的覆盖,可考虑配置发射功率以增加补偿小区的覆盖范围。
(2)RIC控制确认消息的增强设计
为支持图2步骤3和图3步骤3中E2节点向Near-RT RIC反馈节能控制动作的执行结果,将在RIC控制确认消息中携带RIC控制结果IE。
考虑在RIC控制结果IE中增加节能反馈的参数如下,可针对节能小区是否进入节能模式以及补偿小区是否进入节能补偿模式联合反馈。
表4 RIC控制结果IE中支持的控制样式X的参数定义
如果某小区的节能模式配置失败,可将节能模式激活状态置为 “deactivated”来表示。
(3)上报消息的增强设计
为支持图2步骤4和图3步骤4中E2节点可向Near-RT RIC上报小区激活状态,需要增强现有的报告服务。在订阅报告时,需要设定相应的报告内容和该报告对应的触发条件(Event Trigger Definition)。
考虑在E2SM-RC现有上报服务中的报告样式(Report Style)3的E2节点上报支持的具体参数中增加小区激活状态(Cell Activation Status)。
表5 E2节点上报支持的具体参数
该报告样式3的对应的触发条件样式(Event Trigger Style)3为E2节点通知改变,考虑新增一项触发条件为小区节能状态发生变化。
表6触发条件样式3支持的触发条件
当E2节点根据节能控制动作中的具体参数配置节能小区和节能模式持续时长后,相应小区将在持续时长后退出节能状态。E2节点可根据负载情况,决定该小区是否被重新激活。由于小区退出节能状态,满足触发条件样式3中小区节能状态改变的触发条件,E2节点将通过报告样式3将小区激活状态的信息反馈给Near-RT RIC。
例二:在E2SM-CCC(Cell Configuration and Control)中对小区级别进行控制,实现小区智能关断。
图5是本公开实施例提供的基于E2SM-CCC的控制流程示意图,如图5所示,本公开实施例提供一种节能控制方法包括以下步骤:
步骤1:Near-RT RIC和E2节点之间建立报告相关的RIC订阅,收集配置、性能指标和测量报告等信息。
步骤2:E2节点根据订阅的要求,发送RIC指示消息,包含节能相关的上报信息,例如小区的负载相关信息、小区的流量信息、小区的能效或者小区的功耗相关测量报告。
步骤3:Near-RT RIC根据E2节点上报的信息分析数据,并执行AI/ML模型推理,根据优化目标或者策略,决定发起对E2节点的节能控制。
步骤4:Near-RT RIC发送RIC控制请求消息,其中RAN功能ID指示为E2SM-CCC,包含E2SM-CCC中定义的参数对E2节点进 行控制。
步骤5:E2节点根据Near-RT RIC指定的控制命令,执行小区关断的配置。E2节点执行该动作可进一步反馈RIC控制确认消息给Near-RT RIC。
上述步骤中,部分消息的增强设计包括以下几个方面:
(1)RIC控制请求消息的增强设计。
针对已定义的控制样式2:小区配置和控制中可控的具体参数,考虑在小区级无线接入网配置结构(Cell-level RAN Configuration Structures)中添加开放式节能模式管理功能(O-ESManagementFunction)支持节能的新特性。
表7 E2SM-CCC中控制样式2支持的RAN配置结构
其中开放式节能模式管理功能的具体参数参考表8。
表8开放式节能模式管理功能的参数定义


使用开放式节能模式管理功能配置时,若采用图2中的方式,则可增加原始小区的节能模式持续时间(ESDurationforOriginalCell)和候选小区的节能补偿模式持续时间(CompensationDurationforCandidateCell)的参数作为节能模式持续时间的指示。若采用图3中的方式,上述两参数无需配置。
(2)RIC控制确认消息
针对图2中的步骤3和图3中的步骤3,E2节点向Near-RT RIC反馈节能控制执行结果,将在RIC控制确认消息中携带RIC控制结果IE。目前E2SM-CCC中定义的小区级别的控制结果中支持对表8中参数配置的结果反馈,即可反馈节能状态配置的情况。针对反馈节能模式中的参数是否配置成功,配置成功的参数则放在RAN配置结构成功列表(RAN Configuration Structures Accepted List)中,失败则放在RAN配置结构失败列表(RAN Configuration Structures Failed List)。
(3)RIC指示上报消息
E2SM-CCC目前定义了小区级别配置的上报,当上述参数发生变化时,E2节点可直接触发并上报,例如上报节能状态的改变。
图6是本公开实施例提供的节能控制方法的流程示意图之二,如图6所示,本公开实施例提供一种节能控制方法,其执行主体可以为E2节点。该方法包括:
