背景技术
随着5G(5th Generation Mobile Communication Technology，第五代移动通信技术)网络演进，5G标准协议引入了NWDAF(Network Data Analytics Function，网络数据分析功能)来收集无线资源和核心网元运行情况，NWDAF能够获取网络资源，并对资源进行配置和控制，其中，在对小区拥塞信息进行配置的过程中，当UE(User Equipment，用户设备)发起会话建立时，SMF(Session Management Function，会话管理功能)向PCF(Policy Control Function，策略控制功能)发起会话策略关联建立请求，PCF根据切片、分析类型、小区位置等信息得到该小区拥塞信息的NWDAF，并向NWDAF获取该小区的小区拥塞信息，最后PCF根据小区拥塞类型及等级进行决策，并提供会话级的QoS(Quality of Service，服务质量)保障，然而，在小区拥塞信息配置过程中仍然存在对用户无差别拥塞保障、QoS保障不精准、资源利用率低等问题，从而不能对资源进行有效配置和控制。
