为了便于更加清晰地理解本公开各实施例的技术方案,首先对本公开各实施例相关的一些技术内容进行介绍。
E2接口是连接Near-RT RIC与E2节点间的逻辑接口,Near-RT RIC可连接到多个E2节点。一个E2节点仅连接一个Near-RT RIC。目前O-RAN的E2应用协议(E2Application Protocol,E2AP)规范中,RIC控制过程用于Near-RT RIC向特定E2节点发起特定功能控制。
图1为相关技术提供的RIC控制过程示意图,如图1所示,Near-RT RIC启动控制过程,向单个E2节点发送RIC控制请求(Control Request)消息,该消息具体定义如表1所示。表1中,IE type and reference表示相应IE的定义可参考E2AP中的具体章节(section),比如Message Type的定义可参考section 9.2.3。
表1 RIC控制请求消息
当RIC控制确认请求(Control Ack Request)信元(Information Element,IE)存在并被设置为Ack或者不存在时,Near-RT RIC都将启动定时器TRICcontrol并等待E2节点反馈消息。
E2节点接收到RIC控制请求消息后,确定目标功能,根据E2服务模型(E2Service Model,E2SM)规范中定义的RIC控制头(Control Header)和RIC控制消息(Control Message)IE的具体控制指令启动相应的RAN功能完成配置。如果RIC控制确认请求IE存在并被设置为Ack或者不存在时,当E2节点成功处理RIC控制过程的指定动作时,E2节点将反馈RIC控制确认(CONTROL ACKNOWLEDGE)消息并继续本地处理。
当RIC控制确认请求IE存在且被设置为“NoAck”,E2节点无需反馈控制执行后的Ack消息。
当Near-RT RIC接收到RIC控制确认消息后,将停止定时器TRICcontrol并认为本次控制过程成功执行。RIC控制确认消息的具体内容如表2所示。表2中,IE type and reference表示相应IE的定义可参考E2AP中的具体章节
(section),比如Message Type的定义可参考section 9.2.3。
表2 RIC控制确认消息
当E2节点未能成功执行特定的控制动作,E2节点将反馈RIC控制失败(CONTROL FAILURE)消息,并携带合适的Cause值。RIC控制失败消息的具体内容如表3所示。表3中,IE type and reference表示相应IE的定义可参考E2AP中的具体章节(section),比如Message Type的定义可参考section9.2.3。
表3 RIC控制失败消息
图1所示的RIC控制过程面向单个E2节点设计,仅能分别独立发起对单个E2节点的控制流程。由于E2节点接收到控制指令后只能独立处理并立即实施,考虑到消息传输时延、处理时延的不确定性,Near-RT RIC无法保证多E2节点协同配置的同步性,因而无法满足类似协作多点-协作调度(Coordinated Multipoint-Coordinated Scheduling,CoMP-CS)等对时间同步要
求高、需要多节点间较强协作关系的场景中多节点协同控制的需求。
此外,当RIC的控制指令下发到E2节点后,E2节点根据控制服务的具体内容本地进行处理,一般认为该外部的控制优化指令生效后,E2节点之后将继续按照本地功能逻辑执行后续处理,智能控制指令的持续性不能保证,E2节点在协调本地处理和智能处理上存在潜在冲突。
针对上述问题,本公开各实施例提供了解决方案,以处理连接到相同Near-RT RIC的多个E2节点协同控制的问题,可实现多节点间协同资源优化配置和调度,提升资源优化的灵活性和有效性。
图2为本公开实施例提供的多节点协同控制方法的流程示意图之一,该方法可应用于近实时无线接入网智能控制器Near-RT RIC,如图2所示,该方法包括如下步骤:
步骤200、向多个接入网设备分别发送第一RIC控制请求消息,第一RIC控制请求消息中包含第一信元,第一信元用于指示接入网设备执行智能控制动作的时间信息。
具体地,本公开实施例中,接入网设备可以是E2节点,Near-RT RIC可连接到多个E2节点,一个E2节点仅连接一个Near-RT RIC。
为了实现多节点协同控制,Near-RT RIC可以向多个E2节点分别发送第一RIC控制请求消息,第一RIC控制请求消息中包含第一信元,该第一信元可用于指示接收到第一RIC控制请求消息的E2节点基于第一信元所指示的时间信息执行智能控制动作(即Near-RT RIC指定的控制动作),比如第一信元可以指示E2节点执行智能控制动作的起始时间、结束时间、持续时间等时间相关信息。
接收到第一RIC控制请求消息的E2节点,便可以根据该第一RIC控制请求消息中包含的第一信元,确定执行智能控制动作的时间信息,从而在相应的时间执行相应的智能控制动作。
图3为本公开实施例提供的多节点协同控制示意图,如图3所示,Near-RT RIC支持对多个E2节点发起同步的协同控制指令,实现对多个E2节点的同步控制。
在一些实施例中,Near-RT RIC向多个E2节点分别发送的第一RIC控制请求消息中包含的第一信元,其所指示的时间信息均相同,从而便于实现对多个E2节点的同步控制。
在一些实施例中,Near-RT RIC和其连接的多个E2节点的时钟源可事先完成同步。
在一些实施例中,第一信元可以包括以下一种或多种:
(1)控制起始时间信元(比如Control Start Time IE),用于指示接入网设备执行智能控制动作的起始时间信息。
(2)控制终止时间信元(比如Control End Time IE),用于指示接入网设备执行智能控制动作的终止时间信息。
(3)控制持续时间信元(比如Control Duration IE),用于指示接入网设备执行智能控制动作的持续时间信息。
例如,Near-RT RIC可以在第一RIC控制请求消息中设定Control Start Time IE,携带起始时间信息,接收到该第一RIC控制请求消息的E2节点将在Control Start Time IE指定的起始时刻启动执行智能控制动作;在该动作生效后,E2节点可以本地自主动作覆盖前述智能控制动作。
例如,Near-RT RIC可以在第一RIC控制请求消息中设定Control Start Time IE和Control End Time IE,携带起始时间信息和终止时间信息,接收到该第一RIC控制请求消息的E2节点将在Control Start Time IE指定的起始时刻启动执行智能控制动作,该智能控制动作至少持续到Control End Time IE所指时刻;Control End Time IE所指时刻之后,E2节点可以本地自主动作覆盖前述智能控制动作。
例如,Near-RT RIC可以在第一RIC控制请求消息中设定Control End Time IE,携带终止时间信息,接收到该第一RIC控制请求消息的E2节点将立即启动执行智能控制动作,该智能控制动作至少持续到Control End Time IE所指时刻;Control End Time IE所指时刻之后,E2节点可以本地自主动作覆盖前述智能控制动作。
例如,Near-RT RIC可以在第一RIC控制请求消息中设定Control Start
Time IE和Control Duration IE,携带起始时间信息和持续时间信息,接收到该第一RIC控制请求消息的E2节点将在Control Start Time IE指定的起始时刻启动执行智能控制动作,该智能控制动作至少持续Control Duration IE所指时长;Control Start Time(即Control Start Time IE指示的起始时刻)+Control Duration(即Control Duration IE所指时长)所指时刻之后,E2节点可以本地自主动作覆盖前述智能控制动作。
本公开实施例提供的多节点协同控制方法,通过在RIC控制过程的控制指令中包含第一信元,指示E2节点执行智能控制动作的时间信息,可实现Near-RT RIC对多个E2节点的协同控制,从而实现多节点间协同资源优化配置和调度,提升资源优化的灵活性和有效性。
在一些实施例中,第一RIC控制请求消息中包含第一信元,进一步包括以下任一种:
第一RIC控制请求消息中包含RIC控制头信元,RIC控制头信元中包含第一信元;或者,
第一RIC控制请求消息中包含RIC控制消息信元,RIC控制消息信元中包含第一信元。
具体地,本公开实施例中,为实现对多个E2节点协同控制,可以在RIC控制请求消息中加入特定IE(即第一信元)来限定E2节点对智能控制动作的实现。其可以有多种不同的实现方式。
一种实施方式中,可以在E2AP层面实现,在E2AP中修改可保证对所有RIC控制过程均支持。E2AP层面的同步机制会影响到RIC控制请求消息中RIC控制消息(Control Message)IE的所有控制动作,涵盖所有E2SM规范(例如E2SM-无线接入网控制(E2SM-RAN Control,E2SM-RC),E2SM-小区配置和控制(E2SM-Cell Configuration and Control,E2SM-CCC)。
例如,可以在E2AP的RIC控制请求消息中增加Control Start Time IE和Control End Time IE,如表4所示。表4中,IE type and reference表示相应IE的定义可参考E2AP中的具体章节(section),比如Message Type的定义可参考section 9.2.3。
表4 RIC控制请求消息设计(Start time+End time)
例如,可以在E2AP的RIC控制请求消息中增加Control Start Time IE和Control Duration IE,如表5所示。表5中,IE type and reference表示相应IE的定义可参考E2AP中的具体章节(section),比如Message Type的定义可参考section 9.2.3。
表5 RIC控制请求消息设计(Start time+Duration)
一种实施方式中,可以在E2SM层面实现。如果需要限制在某个E2SM中适用(例如E2SM-RC),可以在E2SM层面定义的RIC控制头(Control Header)IE或RIC控制消息(Control Message)IE中增加特定IE(即第一信元)。
在一些实施例中,RIC控制头信元包括支持单个智能控制动作的第一RIC控制头信元,或支持多个智能控制动作的第二RIC控制头信元;或者,
RIC控制消息信元包括支持单个智能控制动作的第一RIC控制消息信元,或支持多个智能控制动作的第二RIC控制消息信元。
例如,以E2SM-RC为例,单个智能控制动作(Control Action)情况下,可以在支持单个智能控制动作的第一RIC Control Header IE或第一RIC Control Message IE中增加Control Start Time IE和Control End Time IE,如表6和表7所示。表6和表7中,IE type and reference表示相应IE的定义可参考E2SM-RC中的具体章节(section),比如UE ID的定义可参考section 9.3.10。
表6 E2SM-RC中RIC Control Header IE设计-单动作格式
注:表6中,Control Action ID仅在RIC Control Header IE中有单个,表明此消息格式仅适用于单个智能控制动作。
表7 E2SM-RC中RIC Control Message IE设计-单动作格式
注:表7中,RAN Parameters仅针对RIC Control Header IE中的单个智能控制动作。
表6和表7中也可以添加Control Start Time IE和Control Duration IE,类似表5的Control Start Time IE和Control Duration IE的模式,此处不再赘述。
当E2节点在E2SM层面支持特定智能控制动作时,E2节点可依照E2SM
层面对控制指令中起始时间和终止时间的处理进行操作。
如果需要更精细的控制,可以在E2SM层面修订,多个智能控制动作情况下可只要求部分智能控制动作同步。例如,以E2SM-RC为例,多个智能控制动作(Control Action)情况下,可以在支持多个智能控制动作的第二RIC Control Message IE中增加Control Start Time IE和Control End Time IE,可针对不同智能控制动作分别限定起始及结束时间,如表8所示。表8中,IE type and reference表示相应IE的定义可参考E2SM-RC中的具体章节(section),比如Indicated Control Style的定义可参考section 9.3.3。
表8 E2SM-RC中RIC Control Message IE设计-多动作格式
注:在多动作情况下可分别对不同Control Action ID指示的智能控制动作分别配置起始和结束时间。表8中也可以添加Control Start Time IE和Control Duration IE,类似表5的Control Start Time IE和Control Duration IE的模式,此处不再赘述。
当对E2节点在E2SM层面部分智能控制动作配置特定IE(第一信元)时,E2节点可依照E2AP层面对控制指令中起始时间和终止时间的处理进行操作;对其他未配置特定IE的智能控制动作,则可不做特殊处理。
在一些实施例中,向多个接入网设备分别发送第一RIC控制请求消息之后,该方法还包括:
向第一接入网设备发送第一消息,第一消息中包含第一RIC请求标识和第一无线接入网功能标识,第一消息用于指示第一接入网设备终止第一RIC请求标识和第一无线接入网功能标识所对应的智能控制动作;
其中,第一RIC请求标识和第一无线接入网功能标识与Near-RT RIC发送给第一接入网设备的第一RIC控制请求消息中包含的RIC请求标识和无线接入网功能标识相同。
具体地,第一接入网设备可以是任意/指定的某个或某些E2节点,在此不做限制。
本公开实施例中,Near-RT RIC可以在向多个E2节点分别发送第一RIC控制请求消息之后,在需要的时候向某个或某些E2节点发送第一消息,用于指示E2节点终止之前施行的智能控制动作。其中,第一消息中包含第一RIC请求标识(Request ID)和第一无线接入网功能标识(RAN Function ID),该第一RIC请求标识和第一无线接入网功能标识用于指示E2节点需要终止的智能控制动作,故该第一RIC请求标识和第一无线接入网功能标识与Near-RT RIC发送给E2节点的第一RIC控制请求消息中包含的RIC请求标识和无线接入网功能标识相同。
接收到第一消息的E2节点,便可以根据该第一消息中包含的第一RIC请求标识和第一无线接入网功能标识,终止相应的智能控制动作。
在一些实施例中,第一消息可以包括以下任一种:
(1)第二RIC控制请求消息,第二RIC控制请求消息中包含控制终止信元,控制终止信元用于指示第一接入网设备终止第一RIC请求标识和第一无线接入网功能标识所对应的智能控制动作。
例如,Near-RT RIC可以向E2节点发送第二RIC控制请求消息,用于指
示E2节点终止之前施行的智能控制动作。该第二RIC控制请求消息可以是在已有RIC控制请求消息中增加可选IE:控制终止信元(Control Termination IE)。
一种实施方式中,可以在RIC控制请求消息中携带第一RIC请求标识和第一无线接入网功能标识,在E2AP层面添加可选IE:Control Termination;或者在E2SM层面的RIC Control Message IE中增加可选IE:Control Termination。
(2)第三RIC控制请求消息,第三RIC控制请求消息中不包含RIC控制头信元和RIC控制消息信元。
例如,Near-RT RIC可以向E2节点发送第三RIC控制请求消息,用于指示E2节点终止之前施行的智能控制动作。该第三RIC控制请求消息可以是将已有RIC控制请求消息中的RIC控制头信元和RIC控制消息信元改为可选项,当Near-RT RIC需要取消此前的智能控制动作时,RIC控制请求消息只需携带相同RIC请求标识和无线接入网功能标识,不包含RIC控制头信元和RIC控制消息信元,即有效控制信息为空。E2节点接收该消息后,便可以终止该RIC请求标识和无线接入网功能标识对应的智能控制动作。
(3)RIC控制取消消息。
例如,可以定义新的消息:RIC控制取消(RIC CONTROL CANCEL)消息,用于指示E2节点终止之前施行的智能控制动作。RIC控制取消消息的消息内容如表9所示。表9中,IE type and reference表示相应IE的定义可参考E2AP中的具体章节(section),比如Message Type的定义可参考section 9.2.3。
表9 RIC控制取消消息
Near-RT RIC发送给E2节点的RIC控制取消消息中的RIC请求标识和无线接入网功能标识,需对应之前发送给该E2节点的第一RIC控制请求消息中相应智能控制动作的RIC请求标识和无线接入网功能标识。当E2节点接收该RIC控制取消消息后,终止消息中包含的RIC请求标识和无线接入网功能标识所对应的智能控制动作。
在一些实施例中,向第一接入网设备发送第一消息,包括:
在确定多个接入网设备中至少一个接入网设备未成功执行智能控制动作的情况下,向成功执行智能控制动作的接入网设备发送第一消息。
具体地,本公开实施例中,Near-RT RIC在向多个E2节点分别发送第一RIC控制请求消息之后,若确定该多个E2节点中至少一个E2节点未成功执行智能控制动作,比如由于传输时延、不同E2节点本地处理差异等原因,导致至少有一个E2节点未成功执行智能控制动作,则Near-RT RIC可以向成功执行智能控制动作的E2节点发送第一消息,以指示成功执行智能控制动作的E2节点终止此前的智能控制动作。
在一些实施例中,确定多个接入网设备中至少一个接入网设备未成功执行智能控制动作,可以包括:
接收到多个接入网设备中至少一个接入网设备发送的RIC控制失败消息;或者,
在发送第一RIC控制请求消息后的指定时长内,未接收到多个接入网设备中全部接入网设备发送的RIC控制确认消息。
具体地,一种情况下,Near-RT RIC在向多个E2节点分别发送第一RIC控制请求消息后,若某个E2节点未成功执行智能控制动作,该E2节点可以向Near-RT RIC反馈RIC控制失败(Control Failure)消息,从而Near-RT RIC可以确定该E2节点未成功执行智能控制动作。
另一种情况下,Near-RT RIC在向多个E2节点分别发送第一RIC控制请求消息后,可以启动一个计时器,若在指定时长内(比如计时器超时)未收集到所有E2节点反馈的RIC控制确认(Control Acknowledge)消息,则Near-RT RIC可以认为未反馈RIC控制确认消息的E2节点未成功执行智能控制动
作。
上述两种情况下,Near-RT RIC可以认为本次多节点同步控制过程执行失败,Near-RT RIC可以向成功执行智能控制动作的E2节点发送第一消息,以指示成功执行智能控制动作的E2节点终止此前的智能控制动作。
图4为本公开实施例提供的多节点协同控制方法的流程示意图之二,该方法可应用于接入网设备,如图4所示,该方法包括如下步骤:
步骤400、接收近实时无线接入网智能控制器Near-RT RIC发送的第一RIC控制请求消息,第一RIC控制请求消息中包含第一信元,第一信元用于指示接入网设备执行智能控制动作的时间信息。
步骤401、基于第一信元,执行智能控制动作。
具体地,本公开实施例中,接入网设备可以是E2节点,Near-RT RIC可连接到多个E2节点,一个E2节点仅连接一个Near-RT RIC。
为了实现多节点协同控制,Near-RT RIC可以向多个E2节点分别发送第一RIC控制请求消息,第一RIC控制请求消息中包含第一信元,该第一信元可用于指示接收到第一RIC控制请求消息的E2节点基于第一信元所指示的时间信息执行智能控制动作(即Near-RT RIC指定的控制动作),比如第一信元可以指示E2节点执行智能控制动作的起始时间、结束时间、持续时间等时间相关信息。
接收到第一RIC控制请求消息的E2节点,便可以根据该第一RIC控制请求消息中包含的第一信元,确定执行智能控制动作的时间信息,从而在相应的时间执行相应的智能控制动作。
在一些实施例中,Near-RT RIC向多个E2节点分别发送的第一RIC控制请求消息中包含的第一信元,其所指示的时间信息均相同,从而便于实现对多个E2节点的同步控制。
在一些实施例中,Near-RT RIC和其连接的多个E2节点的时钟源可事先完成同步。
在一些实施例中,第一信元可以包括以下一种或多种:
(1)控制起始时间信元(比如Control Start Time IE),用于指示接入网
设备执行智能控制动作的起始时间信息。
(2)控制终止时间信元(比如Control End Time IE),用于指示接入网设备执行智能控制动作的终止时间信息。
(3)控制持续时间信元(比如Control Duration IE),用于指示接入网设备执行智能控制动作的持续时间信息。
例如,Near-RT RIC可以在第一RIC控制请求消息中设定Control Start Time IE,携带起始时间信息,接收到该第一RIC控制请求消息的E2节点将在Control Start Time IE指定的起始时刻启动执行智能控制动作;在该动作生效后,E2节点可以本地自主动作覆盖前述智能控制动作。
例如,Near-RT RIC可以在第一RIC控制请求消息中设定Control Start Time IE和Control End Time IE,携带起始时间信息和终止时间信息,接收到该第一RIC控制请求消息的E2节点将在Control Start Time IE指定的起始时刻启动执行智能控制动作,该智能控制动作至少持续到Control End Time IE所指时刻;Control End Time IE所指时刻之后,E2节点可以本地自主动作覆盖前述智能控制动作。
例如,Near-RT RIC可以在第一RIC控制请求消息中设定Control End Time IE,携带终止时间信息,接收到该第一RIC控制请求消息的E2节点将立即启动执行智能控制动作,该智能控制动作至少持续到Control End Time IE所指时刻;Control End Time IE所指时刻之后,E2节点可以本地自主动作覆盖前述智能控制动作。
例如,Near-RT RIC可以在第一RIC控制请求消息中设定Control Start Time IE和Control Duration IE,携带起始时间信息和持续时间信息,接收到该第一RIC控制请求消息的E2节点将在Control Start Time IE指定的起始时刻启动执行智能控制动作,该智能控制动作至少持续Control Duration IE所指的持续时长;起始时刻+持续时长所指时刻之后,E2节点可以本地自主动作覆盖前述智能控制动作。
本公开实施例提供的多节点协同控制方法,通过在RIC控制过程的控制指令中包含第一信元,指示E2节点执行智能控制动作的时间信息,可实现
Near-RT RIC对多个E2节点的协同控制,从而实现多节点间协同资源优化配置和调度,提升资源优化的灵活性和有效性。
在一些实施例中,第一RIC控制请求消息中包含第一信元,进一步包括以下任一种:
第一RIC控制请求消息中包含RIC控制头信元,RIC控制头信元中包含第一信元;或者,
第一RIC控制请求消息中包含RIC控制消息信元,RIC控制消息信元中包含第一信元。
具体地,本公开实施例中,为实现对多个E2节点协同控制,可以在RIC控制请求消息中加入特定IE(即第一信元)来限定E2节点对智能控制动作的实现。其可以有多种不同的实现方式。
一种实施方式中,可以在E2AP层面实现,在E2AP中修改可保证对所有RIC控制过程均支持。E2AP层面的同步机制会影响到RIC控制请求消息中RIC控制消息(Control Message)IE的所有控制动作,涵盖所有E2SM规范(例如E2SM-RC,E2SM-CCC)。
例如,可以在E2AP的RIC控制请求消息中增加Control Start Time IE和Control End Time IE,如表4所示;或者,可以在E2AP的RIC控制请求消息中增加Control Start Time IE和Control Duration IE,如表5所示。
一种实施方式中,可以在E2SM层面实现。如果需要限制在某个E2SM中适用(例如E2SM-RC),可以在E2SM层面定义的RIC控制头(Control Header)IE或RIC控制消息(Control Message)IE中增加特定IE(即第一信元)。
在一些实施例中,RIC控制头信元包括支持单个智能控制动作的第一RIC控制头信元,或支持多个智能控制动作的第二RIC控制头信元;或者,
RIC控制消息信元包括支持单个智能控制动作的第一RIC控制消息信元,或支持多个智能控制动作的第二RIC控制消息信元。
例如,以E2SM-RC为例,单个智能控制动作(Control Action)情况下,可以在支持单个智能控制动作的第一RIC Control Header IE或第一RIC
Control Message IE中增加Control Start Time IE和Control End Time IE,如表6和表7所示。
如果需要更精细的控制,可以在E2SM层面修订,多个智能控制动作情况下可只要求部分智能控制动作同步。例如,以E2SM-RC为例,多个智能控制动作(Control Action)情况下,可以在支持多个智能控制动作的第二RIC Control Message IE中增加Control Start Time IE和Control End Time IE,可针对不同智能控制动作分别限定起始及结束时间,如表8所示。
在一些实施例中,接收近实时无线接入网智能控制器Near-RT RIC发送的第一RIC控制请求消息之后,该方法还包括:
在确定满足以下任一项的情况下,向Near-RT RIC发送RIC控制失败消息:
(1)第一信元指示的接入网设备执行智能控制动作的起始时刻,在接入网设备接收到第一RIC控制请求消息的时刻之前。
例如,如果E2节点接收到第一RIC控制请求消息,发现Control Start Time(即Control Start Time IE指示的起始时刻)存在但已过期(收到第一RIC控制请求消息的时刻在Control Start Time之后),由于Near-RT RIC发起相关控制指令需要不同E2节点同步进行配置,当控制起始时间失效,E2节点可以认为该控制指令无法执行,并反馈RIC控制失败(CONTROL FAILURE)消息给Near-RT RIC。在一些实施例中,RIC控制失败消息中可以携带相应的原因(Cause)值,比如:控制起始时间失效(Control Start Time expired)。
(2)第一信元指示的接入网设备执行智能控制动作的终止时刻,在接入网设备接收到第一RIC控制请求消息的时刻之前。
例如,如果E2节点接收到第一RIC控制请求消息,发现Control End Time(即Control End Time IE指示的终止时刻)存在但已过期(收到第一RIC控制请求消息的时刻在Control End Time之后),则E2节点可以判定控制终止时间已失效,将反馈RIC控制失败消息给Near-RT RIC。在一些实施例中,RIC控制失败消息中可以携带相应的原因值,比如:控制终止时间失效(Control End Time expired)。
(3)第一信元指示的接入网设备执行智能控制动作的终止时刻,在第一信元指示的接入网设备执行智能控制动作的起始时刻之前。
例如,如果E2节点接收到第一RIC控制请求消息,发现Control End Time与Control Start Time均存在但Control End Time超前于Control Start Time,则E2节点可以反馈RIC控制失败消息给Near-RT RIC。在一些实施例中,RIC控制失败消息中可以携带相应的原因值,比如:控制终止时间超前于控制起始时间(Control End Time ahead of Control Start Time)。
(4)第一信元仅指示接入网设备执行智能控制动作的持续时间信息。
例如,如果E2节点接收到第一RIC控制请求消息,发现消息中仅指示了Control Duration,则E2节点可以反馈RIC控制失败消息给Near-RT RIC。在一些实施例中,RIC控制失败消息中可以携带相应的原因值,比如:缺少控制开始时间(Control Start Time missing)。
在一些实施例中,接收近实时无线接入网智能控制器Near-RT RIC发送的第一RIC控制请求消息之后,该方法还包括:
接收Near-RT RIC发送的第一消息,第一消息中包含第一RIC请求标识和第一无线接入网功能标识,第一消息用于指示接入网设备终止第一RIC请求标识和第一无线接入网功能标识所对应的智能控制动作;
其中,第一RIC请求标识和第一无线接入网功能标识与第一RIC控制请求消息中包含的RIC请求标识和无线接入网功能标识相同。
具体地,本公开实施例中,Near-RT RIC可以在向多个E2节点分别发送第一RIC控制请求消息之后,在需要的时候向某个或某些E2节点发送第一消息,用于指示E2节点终止之前施行的智能控制动作。其中,第一消息中包含第一RIC请求标识(Request ID)和第一无线接入网功能标识(RAN Function ID),该第一RIC请求标识和第一无线接入网功能标识用于指示E2节点需要终止的智能控制动作,故该第一RIC请求标识和第一无线接入网功能标识与Near-RT RIC发送给E2节点的第一RIC控制请求消息中包含的RIC请求标识和无线接入网功能标识相同。
接收到第一消息的E2节点,便可以根据该第一消息中包含的第一RIC请
求标识和第一无线接入网功能标识,终止相应的智能控制动作。
在一些实施例中,第一消息包括以下任一种:
(1)第二RIC控制请求消息,第二RIC控制请求消息中包含控制终止信元,控制终止信元用于指示接入网设备终止第一RIC请求标识和第一无线接入网功能标识所对应的智能控制动作。
例如,Near-RT RIC可以向E2节点发送第二RIC控制请求消息,用于指示E2节点终止之前施行的智能控制动作。该第二RIC控制请求消息可以是在已有RIC控制请求消息中增加可选IE:控制终止信元(Control Termination IE)。
一种实施方式中,可以在RIC控制请求消息中携带第一RIC请求标识和第一无线接入网功能标识,在E2AP层面添加可选IE:Control Termination;或者在E2SM层面的RIC Control Message IE中增加可选IE:Control Termination。
(2)第三RIC控制请求消息,第三RIC控制请求消息中不包含RIC控制头信元和RIC控制消息信元。
例如,Near-RT RIC可以向E2节点发送第三RIC控制请求消息,用于指示E2节点终止之前施行的智能控制动作。该第三RIC控制请求消息可以是将已有RIC控制请求消息中的RIC控制头信元和RIC控制消息信元改为可选项,当Near-RT RIC需要取消此前的智能控制动作时,RIC控制请求消息只需携带相同RIC请求标识和无线接入网功能标识,不包含RIC控制头信元和RIC控制消息信元,即有效控制信息为空。E2节点接收该消息后,便可以终止该RIC请求标识和无线接入网功能标识对应的智能控制动作。
(3)RIC控制取消消息。
例如,可以定义新的消息:RIC控制取消(RIC CONTROL CANCEL)消息,用于指示E2节点终止之前施行的智能控制动作。RIC控制取消消息的消息内容如表9所示。
Near-RT RIC发送给E2节点的RIC控制取消消息中的RIC请求标识和无线接入网功能标识,需对应之前发送给该E2节点的第一RIC控制请求消
息中相应智能控制动作的RIC请求标识和无线接入网功能标识。当E2节点接收该RIC控制取消消息后,终止消息中包含的RIC请求标识和无线接入网功能标识所对应的智能控制动作。
本公开各实施例提供的方法是基于同一申请构思的,因此各方法的实施可以相互参见,重复之处不再赘述。
以下通过具体应用场景的实施例对本公开各上述实施例提供的方法进行举例说明。
实施例1:在RIC控制请求消息中增加控制起始时间信元和控制终止时间信元(模式一)。
Near-RT RIC通过在RIC控制请求消息中设定Control Start Time IE和Control End Time IE,可确保多个E2节点执行控制的起始时间和结束时间相同,完成同步的配置。
E2节点接收到RIC控制请求消息,对于消息收到时刻<Control Start Time(控制起始时刻)<Control End Time(控制终止时刻)的情况:
1)当Control Start Time IE与Control End Time IE同时存在时,E2节点将在Control Start Time IE指定的起始时刻启动执行智能控制动作,该智能控制动作至少持续到Control End Time IE所指时刻;Control End Time IE所指时刻之后,E2节点可以本地自主动作覆盖前述智能控制动作。
2)当只有Control Start Time IE存在时,E2节点将在Control Start Time IE指定的起始时刻启动执行智能控制动作;在该动作生效后,E2节点可以本地自主动作覆盖前述智能控制动作。
3)当只有Control End Time IE存在时,E2节点立即启动执行智能控制动作,该智能控制动作至少持续到Control End Time IE所指时刻;Control End Time IE所指时刻之后,E2节点可以本地自主动作覆盖前述智能控制动作。
对于CoMP-CS场景,不同基站带不同小区,可根据协作调度的控制指令设定的起始时间同步不同小区的资源配置,减少小区边缘用户的干扰。
对模式一,RIC同步控制流程有如下三种情况:
Case 1-1:图5为本公开实施例提供的RIC同步控制流程示意图之一,如
图5所示,Near-RT RIC对多个E2节点进行同步控制,Control Start Time(控制起始时刻)和Control End Time(控制终止时刻)均存在且有效,该RIC同步控制过程主要包括:
1、Near-RT RIC发送RIC控制请求消息给不同E2节点(如E2节点1和E2节点2),消息中设定相同的Control Start Time和Control End Time。
2、E2节点接收到RIC控制请求消息,判定Control Start Time和Control End Time均存在且有效,可反馈RIC控制确认消息给Near-RT RIC告知接受该控制指令。
3、不同的E2节点将在指定的Control Start Time同步启动执行智能控制动作,并持续到Control End Time。Control End Time之后,E2节点可以根据本地自主过程覆盖前述智能控制动作。
Case 1-2:图6为本公开实施例提供的RIC同步控制流程示意图之二,如图6所示,Near-RT RIC对多个E2节点进行同步控制,只有Control Start Time(控制起始时刻)存在且有效,该RIC同步控制过程主要包括:
1、Near-RT RIC发送RIC控制请求消息给不同E2节点(如E2节点1和E2节点2),消息中设定相同的Control Start Time。
2、E2节点接收到RIC控制请求消息,判定Control Start Time存在且有效,可反馈RIC控制确认消息给Near-RT RIC告知接受该控制指令。
3、不同的E2节点将在指定的Control Start Time同步启动执行控制动作,在该动作生效后,E2节点可以本地自主动作覆盖前述智能控制动作。
Case 1-3:图7为本公开实施例提供的RIC同步控制流程示意图之三,如图7所示,Near-RT RIC对多个E2节点进行同步控制,只有Control End Time(控制终止时刻)存在且有效,该RIC同步控制过程主要包括:
1、Near-RT RIC发送RIC控制请求消息给不同E2节点(如E2节点1和E2节点2),消息中设定相同的Control End Time。
2、E2节点接收到RIC控制请求消息,判定仅Control End Time存在且有效,可反馈RIC控制确认消息给Near-RT RIC告知接受该控制指令。
3、不同的E2节点在接收到RIC控制请求消息后立即启动执行智能控制
动作(不能确保不同E2节点同时启动),该动作持续至Control End Time;Control End Time之后,E2节点可以本地自主动作覆盖前述智能控制动作。
实施例2:在RIC控制请求消息中增加控制起始时间信元和控制持续时间信元(模式二)。
E2节点接收到RIC控制请求消息,对于消息收到时刻<Control Start Time(控制起始时刻)的情况:
1)E2节点将在Control Start Time IE指定的起始时刻启动执行智能控制动作,该智能控制动作至少持续Control Duration时长;Control Start Time+Control Duration所指时刻之后,E2节点可以本地自主动作覆盖前述智能控制动作。
2)当只有Control Start Time IE存在时,E2节点将在Control Start Time IE指定的起始时刻启动执行智能控制动作;在该动作生效后,E2节点可以本地自主动作覆盖前述智能控制动作。
3)当只有Control Duration IE存在时,E2节点启动差错控制过程(即异常处理过程)。
对于模式二,E2节点需将Control Start Time+Control Duration所指时刻作为控制终止时刻,判断是否失效来执行本地操作。
Case 2-1:图8为本公开实施例提供的RIC同步控制流程示意图之四,如图8所示,Near-RT RIC对多个E2节点进行同步控制,Control Start Time(控制起始时刻)和Control Duration(控制持续时间)均存在且有效,该RIC同步控制过程主要包括:
1、Near-RT RIC发送RIC控制请求消息给不同E2节点(如E2节点1和E2节点2),消息中设定相同的Control Start Time和Control Duration。
2、所有E2节点接收到RIC控制请求消息,判定Control Start Time和Control Duration均存在且有效,可反馈RIC控制确认消息给Near-RT RIC告知接受该控制指令。
3、不同的E2节点将在指定的Control Start Time同步启动执行智能控制动作,持续Control Duration所指时长。持续时间之后,E2节点可以根据本地
自主过程覆盖前述智能控制动作。
Case 2-2:当只有Control Start Time存在且有效时,同Case 1-2。
Case 2-3:当只有Control Duration存在时,由于需要E2节点间强同步,仅有控制动作持续时间无法保证E2节点同步处理,E2节点将启动异常处理过程。
实施例3:异常处理。
E2节点侧:
模式一:
a)如果E2节点接收到RIC控制请求消息,发现Control Start Time存在但已过期(收到消息时刻>Control Start Time),由于Near-RT RIC发起相关控制指令需要不同E2节点同步进行配置,当Control Start Time失效,E2节点将认为该控制命令无法执行,并反馈RIC控制失败消息给Near-RT RIC,携带相应Cause值:Control Start Time expired。
b)如果E2节点接收到RIC控制请求消息,发现Control End Time存在但时间已过期,则判定Control End Time已失效,将反馈RIC控制失败消息给Near-RT RIC,并携带相应Cause值:Control End Time expired。
c)如果E2节点接收到RIC控制请求消息,发现Control End Time与Control Start Time均存在但Control End Time超前于Control Start Time,将反馈RIC控制失败消息给Near-RT RIC,并携带相应Cause值:Control End Time ahead of Control Start Time。
模式二:
a)同模式一a)。
b)如果E2节点接收到RIC控制请求消息,发现仅有Control Duration存在,将反馈RIC控制失败消息给Near-RT RIC,并携带相应Cause值:Control Start Time missing。
Near-RT RIC侧:
如果Near-RT RIC同时向多个E2节点发送控制指令,需要多个E2节点完成强协作关系的同步控制,但由于传输时延、不同E2节点本地处理差异等
原因,至少有一个E2节点执行失败并反馈控制失败,Near-RT RIC需要指定其他E2节点也停止相应控制动作。
此外,当Near-RT RIC在发送多条RIC控制请求消息后,需要E2节点反馈接受情况,在指定计时器时间内未收集到所有E2节点反馈的RIC控制确认消息,则将认为该同步控制指令执行失败,Near-RT RIC需要指定其他E2节点也停止相应控制动作。
上述两种情况下,Near-RT RIC可向其他反馈成功执行的E2节点再发送RIC控制请求消息,该消息中可包含信息指示终止此前的控制动作。
现有RIC控制请求消息的设计暂未支持终止此前控制动作,可考虑在RIC控制请求消息中携带与之前施行的控制动作相同的RIC请求标识(RIC Request ID)和RAN功能标识(RAN Function ID),在E2AP层面添加可选IE:Control Termination;或者在E2SM层面的RIC Control Message IE中增加可选IE:Control Termination。
图9为本公开实施例提供的异常处理过程示意图,如图9所示,Near-RT RIC可以通过在RIC控制请求消息中携带Control Termination(控制终止信元),终止控制过程。主要异常处理过程包括:
1、Near-RT RIC发送RIC控制请求消息给不同E2节点(如E2节点1和E2节点2),分别携带RIC Request ID和RAN Function ID,消息中设定相同的Control Start Time和Control End Time。
2、E2节点1成功接受该控制指令,反馈RIC控制确认消息给Near-RT RIC告知接受该控制指令;但E2节点2出错,向Near-RT RIC反馈控制失败消息。
3、Near-RT RIC接收到不同E2节点的反馈信息,发现至少有一个E2节点无法执行,将取消所有E2节点处的控制操作。
4、Near-RT RIC向E2节点1发送与步骤1中携带相同RIC Request ID和RAN Function ID的RIC控制请求消息,消息中携带Control Termination。
5、当E2节点1接收到与此前请求的智能控制动作相同的ID标识,并检测到Control Termination,将终止此前的智能控制动作,E2节点1本地处理
接管当前过程。
终止控制动作,还可通过其他方式实现,例如:
1)修改现有RIC控制请求消息,将RIC Control Header IE和RIC Control Message IE改为可选项。当Near-RT RIC需要取消此前的控制动作时,RIC控制请求消息只需携带相同RIC Request ID和RAN Function ID,不携带RIC Control Header IE和RIC Control Message IE,即有效控制信息为空。E2节点接收该消息后,终止该ID标识(即RIC Request ID和RAN Function ID)对应的智能控制动作。
2)增加新消息RIC CONTROL CANCEL,如表9所示。
本公开各实施例提供的多节点协同控制方法,可实现Near-RT RIC对多个E2节点下发控制时E2节点同步执行该控制指令,实现节点间协同资源优化配置和调度;同时支持E2节点控制指令执行一段时间,协调智能处理和本地处理的优先级和实施持续性,提升资源优化的灵活性和有效性。
