技术领域
本申请涉及移动通信领域，特别是涉及一种无线资源管理方法、存储介质和电子设备。
背景技术
移动通信目前已经发展到5G阶段。5G网络和之前移动网络相比，通过引入了网络切片而对网络进行了重构，并采用了服务化架构，从而为用户提供更丰富的个性化业务。终端(UE，User Equipment)主要通过无线空口接入5G网络并获得服务。其中，无线接入网(RAN，Radio Access Network)负责UE接入网络的空口资源调度和以及空口的连接管理，使得UE通过非接入层信令(NAS，Non-Access Stratum)和核心网的接入和移动管理功能(AMF，Access and Mobility Management function)交互信息。
特别地，5G网络引入了网络数据分析功能(NWDAF，Network Data Analytics Function)来负责获取用户和网络信息。对获取的信息进行处理后，NWDAF生成分析数据，并把分析数据提供给向其订阅的网络功能(NF，Network Function)。用户信息可以包括用户移动信息、用户接入的业务等动态信息，以及签约等静态信息。用户信息可以包括NF的负荷等动态信息和网络部署等静态信息。基于这些静态的用户信息，可以在一定程度上对无线资源进行优化配置，但无法完全满足实际应用需要，尤其是各类移动终端的接入需要。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
应了解，在本申请实施例的描述中，多个(或多项)的含义是两个以上，大于、小于、超过等理解为不包括本数，以上、以下、以内等理解为包括本数。如果有描述到“第一”、“第二”等只是用于区分技术特征为目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量或者隐含指明所指示的技术特征的先后关系。
相对于现有的4G网络，5G网络引入了NWDAF，用于对5G网络进行更自动化的管理和更灵活的使用。具体地，NWDAF作为核心网控制面实体，能够从网络功能、应用功能(AF， Application Function)、操作维护管理(OAM，Operation,Administration,and Maintenance)等位于5G网络架构上的网元获取用户和网络信息。这些信息可被利用以识别接入移动网络的UE及其当前接入的业务。例如，当前网络侧可以基于用户的静态签约信息(例如签约的RFSP)、UE能力(例如是否可以通过IMS提供语音)、用户状态(例如漫游还是本地接入)、接入的业务等信息，从而为UE选择恰当的RFSP。例如，策略控制功能(PCF，Policy Control Functionality)作为核心网控制面实体，负责接入和移动性管理策略、UE策略、会话管理策略和计费规则的功能实体。该功能实体主要根据业务信息和用户签约信息以及运营商的配置信息产生接入和移动性管理策略、UE路由选择策略、用户数据传递的服务质量(QoS，Quality of Service)规则和计费规则等。
然而，不同用户的移动模式(如低移动性用户)、用户的移动习惯、用户接入业务习惯、网络拥塞信息等，是动态变化的。目前网络侧很难根据用户动态变化信息，及时更新用户使用的RFSP。
5G的网络侧可以基于用户的静态签约信息、UE能力、用户状态接入的业务等信息而为UE选择接入方式和频点选择优先级索引(RFSP，Index to RAT/Frequency Selection Priority)。然而，不同用户的移动模式、移动习惯，以及网络拥塞信息等是动态变化的。因此，网络侧难以根据上述动态变化信息而及时更新用户使用的RFSP。
基于此，本申请提出利用NWDAF向5GC NF、AF、OAM或RAN等网元辅助获取5G网络的原始数据，并对获取的原始信息进行处理、产生分析数据，同时结合本地策略动态地调整UE的无线资源管理策略，从而可以使无线资源利用更优，无线拥塞控制更灵活。

其中，用户无线资源管理策略至少包括使用的RFSP和寻呼策略数(包括寻呼区域、寻呼优先级、寻呼辅助数据等等的设置)。上述用户无线资源管理策略的调整可一定程度上实现及时响应用户动态变化信息和/或网络拥塞信息，以充分利用无线资源而避免拥塞。
实际应用时，用户移动模式可以根据具体的应用场景或资源管理要求，分为高移动性、中移动性、低移动性或不移动等多种类型。不同移动性可以是基于用户的历史统计数据进行分类，并可以基于上述历史统计数据对用户的移动性进行预测。
在实际应用时，该方法还可以包括在接收订阅分析数据请求后，所述NWDAF实体可以返回订阅分析数据响应消息。相应地，在接收分析数据通知请求消息后，所述PCF实体或者所述AMF实体可以返回分析数据通知响应消息。
此外，所述NWDAF实体还直接或间接地从AMF实体、集群控制功能TCF实体或AF实体获取目标用户的用户接入业务信息或用户签约信息。相应地，所述PCF实体或者所述AMF实体可以结合上述用户接入业务信息或用户签约信息，确定是否调整用户无线资源管理策略。
本申请的实施例还提供了一种存储介质，存储有计算机可执行指令，计算机可执行指令用于执行上述的无线资源管理方法。
在本申请的一个实施例中，该存储介质存储有计算机可执行指令，该计算机可执行指令被一个或多个控制处理器31执行，例如，被图11所述电子设备30中的一个处理器31执行，可使得上述一个或多个处理器31执行上述的云计算服务方法，例如，执行图1中描述的方法步骤S101至S102、图2中描述的方法步骤S201至S202、图4中描述的方法步骤S301至S302、图6中描述的方法步骤S401至S402、图7中描述的方法步骤S501至S502、图9中描述的方法步骤S601至S603和图10中描述的方法步骤S701至S703。
本申请实施例的方案解决了网络侧难以根据用户动态变化信息和/或小区拥塞信息等无线网络负荷信息，及时更新用户无线资源管理策略的问题。网络侧根据用户动态变化信息和/或小区拥塞信息等无线网络负荷信息，及时更新用户无线资源管理策略，从而可以使无线资源利用更优，无线拥塞控制更灵活。
