为便于理解本公开实施例的技术方案，以下对本公开实施例的相关技术进行说明，以下相关技术作为可选方案与本公开实施例的技术方案可以进行任意结合，其均属于本公开实施例的保护范围。
开放的无线接入网络(O-RAN)由O-RAN联盟提出，相比于现有的无线接入网络架构和功能，O-RAN提出了无线智能控制器(RIC)。图1给出了O-RAN的系统架构图，无线智能控制器包括非实时无线智能控制器(non-RT RIC)和近实时无线智能控制器(near-RT RIC)。
其中，近实时无线智能控制器包括平台功能和xApp实例应用功能。平台功能用以支持xApp实例应用的部署和运行；xApp实例应用是指面向某个应用场景解决某一个问题的xApp，例如负载均衡、负载预测、视频关键质量指标(Key Quality Indicator，KQI)预测、服务质量(Quality of Service，QoS) 和体验质量(Quality of Experience，QoE)优化等。近实时无线智能控制器中的平台也可以称为无线智控平台或者near-RT RIC平台(简称为RIC平台)。
xApp与平台相互采用开放应用编程接口(Open API)进行通讯，xApp可以从平台订阅和获取小区及UE信息，通过分析订阅信息和自身算法作出小区、UE及承载级别的策略和参数调整，将相关策略和调整信息发送给平台。此外，xApp之间也可能存在Open API，通过Open API交互必要信息。近实时无线智能控制器通过E2接口向E2节点订阅xApp所需要的数据，xApp对E2节点的控制命令(如QoS参数调整命令)也通过E2接口向E2节点下发，其中，E2节点可以是中心单元(Centralized Unit，CU)、分布单元(Distributed Unit，DU)、射频拉远单元(Remote Radio Unit，RRU)。近实时无线智能控制器对E2节点的闭环控制时延约在百毫秒级别。协议中定义了订阅上报类型。其中有基于消息事件(Message Event)的上报类型，即E2节点收到空口的无线资源控制(Radio Resource Control，RRC)消息或Xn接口消息时向平台上报。还有一种基于UE信息改变(UE Information Change)的上报类型，即UE离开(释放或切换)或进入小区或UE ID变化时向平台上报。
xApp可运用人工智能算法根据UE上报的信道质量信息以及小区状态信息对UE进行移动性控制(例如切换控制)，然而对不同移动状态(如高速、低速、静止)的UE控制的时间需求不一致，若只根据当前UE上报的信息进行切换控制，可能导致过早/过晚切换，影响切换性能。
为此，提出了本公开实施例的以下技术方案。
本公开实施例的技术方案应用于O-RAN系统架构，在E2接口(即近实时无线智能控制器与E2节点之间的接口)和应用程序编程接口(Application Programming Interface，API)接口(即xApp与RIC平台之间的接口)增加对UE移动状态信息订阅的支持，可以实现RIC平台向E2节点订阅UE移动状态信息，以及xApp向RIC平台订阅UE移动状态信息，为xApp基于UE移动状态信息对UE进行有效移动性控制提供了支撑。
为便于理解本公开实施例的技术方案，以下通过具体实施例详述本公开的技术方案。本公开实施例包括以下内容中的至少部分内容。
图2是本公开实施例提供的信息订阅方法的流程示意图，如图2所示， 所述信息订阅方法包括：
步骤201：第一功能通过第一接口向第二功能发送订阅请求消息；第二功能通过第一接口接收第一功能发送的订阅请求消息；所述订阅请求消息用于订阅UE移动状态信息；其中，所述第一接口为与RIC相关的接口。
步骤202：第二功能通过所述第一接口向所述第一功能上报订阅消息；第一功能通过所述第一接口接收所述第二功能上报的订阅消息。
在一些实施方式中，所述第一接口为E2接口，相应地，所述第一功能为RIC，所述第二功能为E2节点；和/或，所述第一接口为API接口，相应地，所述第一功能为xApp，所述第二功能为RIC平台。
这里，RIC是指近实时无线智能控制器(near-RT RIC)。
这里，E2节点是指CU、DU、RRU等无线接入网络(Radio Access Network，RAN)侧的节点。
这里，E2接口是指RIC与E2节点之间的接口。
这里，RIC平台是指近实时无线智能控制器(near-RT RIC)中的平台，也可以称为无线智控平台。
这里，xApp是指近实时无线智能控制器(near-RT RIC)中的xApp应用实例。
这里，API接口是指RIC平台与xApp之间的接口。
本公开实施例的技术方案中，在E2接口和/或API接口增加对UE移动状态信息订阅的支持，从而使得RIC和/或xApp可以获得UE移动状态信息，根据UE移动状态信息可以更好地指示E2节点对UE进行移动性控制(如切换控制)，有效支持UE移动状态多样化时的移动性控制(如切换控制)。
需要说明的是，本公开实施例中的“订阅请求消息”根据接口类型的不同可以有不同的名称，例如对于E2接口来说，“订阅请求消息”也可以称为“RIC订阅请求消息”。
本公开实施例中的订阅请求和订阅上报不仅适用于RIC与E2节点之间的E2接口，也可以适用于RIC平台与xApp之间的API接口。
本公开实施例中，所述订阅请求消息用于订阅UE移动状态信息，其中，对UE移动状态信息的订阅，可以有如下类型：
1)所述订阅请求消息用于订阅指定UE的移动状态信息。
这里，所述订阅请求消息用于订阅某个或某些指定UE的移动状态信息。例如：所述订阅请求消息用于订阅UE1和UE2的移动状态信息。
2)所述订阅请求消息用于订阅指定移动状态的UE进行上报。
这里，所述订阅请求消息用于订阅某个或某些移动状态的UE进行上报。例如：所述订阅请求消息用于订阅具有移动状态1和移动状态2的UE进行上报。
这里，在一些实施方式中，所述指定移动状态的UE进行上报的内容包括以下至少之一：UE标识、UE的移动状态信息。
本公开实施例中，所述订阅对应的上报类型包括以下至少之一：
第一上报类型，所述第一上报类型为收到订阅消息后或者收到订阅消息后且获得有效的UE移动状态信息后即刻上报；
第二上报类型，所述第二上报类型为周期性上报；
第三上报类型，所述第三上报类型为条件上报。
这里，“订阅对应的上报类型”也可以理解为“订阅的触发条件”，规定了在什么情况下触发UE进行上报。所述订阅请求消息中可以携带所述上报类型。
其中，对于所述第一上报类型，UE在当前移动状态即刻上报。对于所述第二上报类型，UE按照指定周期进行周期性上报。对于所述第三上报类型，条件满足的情况下触发UE进行上报。
在一些实施方式中，所述条件包括以下至少之一：
UE的移动速度变化值超过预设的阈值；
UE的移动速度绝对值达到预设的阈值区间。
这里，当UE的移动速度变化值超过预设的阈值时，触发UE进行上报。或者，当UE的移动速度绝对值达到预设的阈值区间时，触发UE进行上报。
在一些实施方式中，所述条件可能包括时间T的值。基于此，所述条件可以进一步限定为：
UE的移动速度绝对值在时间T内均达到预设的阈值区间；或者，
UE的移动速度绝对值在时间T内的平均值达到预设的阈值区间。
这里，当UE的移动速度绝对值在时间T内均达到预设的阈值区间时，触发UE进行上报。或者，当UE的移动速度绝对值在时间T内的平均值达到预设的阈值区间时，触发UE进行上报。
上述方案中，所述移动状态信息包括移动速度信息和/或移动方向角度信息。其中，移动方向角度指的是UE的移动方向与基站延长线方向的角度。
在一些实施方式中，所述移动速度信息可以通过以下任意一种方式来表示：
方式1-1)所述移动速度信息为移动速度绝对值。
方式1-2)所述移动速度信息为移动速度标识，所述移动速度标识与移动速度绝对值或者移动速度区间范围具有第一对应关系。
这里，所述第一对应关系由协议约定或者由网络配置。例如：网络侧可以在订阅请求消息或E2接口消息或其他消息中的信息元素(Information element，IE)中配置第一对应关系，或者，协议(如RAN功能定义(Function Definition)IE)中定义好第一对应关系。在一个示例中，第一对应关系可以通过一个表格来表示，称为UE移动速度区间参考表格，表格中列出多组数据，每组数据代表了一个UE移动速度区间与一个移动速度标识的对应关系。其中，移动速度标识可以是数字，也可以是字母，也可以是预先定义好的速度标签，如超高速、高速、中速、低速、静止等。以下表1给出了UE移动速度区间参考表格的一个示例。
表1
基于上述第一对应关系，对于条件上报中的条件也可以有相应的表述，例如：UE的移动速度变化值超过预设的阈值，可以表述为：UE的移动速度标识的变化值大于等于阈值M，那么，当UE的移动速度标识从X变化到Y 时，如果X-Y≥M或Y-X≥M，那么认为条件满足，触发UE进行上报。
在一些实施方式中，所述移动方向角度信息可以通过以下任意一种方式来表示：
方式2-1)所述移动方向角度信息为移动方向角度绝对值。
方式2-2)所述移动方向角度信息为移动方向角度标识，所述移动方向角度标识与移动方向角度绝对值或者移动方向角度区间范围具有第二对应关系。
这里，所述第二对应关系由协议约定或者由网络配置。例如：网络侧可以在订阅请求消息或E2接口消息或其他消息中的信息元素(IE)中配置第二对应关系，或者，协议(如RAN Function Definition IE)中定义好第二对应关系。在一个示例中，第二对应关系可以通过一个表格来表示，类似于上述表1。
本公开实施例的技术方案，一方面，为RIC提供UE移动状态信息订阅及上报，有效支撑xApp的切换控制性能。另一方面，优化了UE移动状态信息上报的触发条件，使得UE移动状态信息的上报更加高效，能更好地支持xApp对UE的切换控制。
本公开实施例中，xApp根据UE移动状态信息对UE进行切换控制。在一些实施方式中，xApp根据UE移动状态信息确定UE切换时延需求(可以结合预设的UE移动状态信息与UE切换时延需求之间的对应关系表)，根据UE切换时延需求确定UE切换时间，进而根据所确定的UE切换时间触发UE执行切换。其中，UE移动速度越高，则UE切换时延需求越小；反之，UE移动速度越低，则UE切换时延需求越大。如此，可以避免UE过早或过晚切换，提高切换性能。
