相关申请的交叉引用
本申请基于申请号为201710309151.9、申请日为2017年05月04日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此以全文引入的方式引入本申请。
技术领域
本发明涉及通信领域，具体而言，涉及一种会话分流的方法及装置、设备、存储介质。
背景技术
相关技术在5G(New Radio)网络中，将存在gNB(Next Generation Node B，下一代基站)、eLTE(enhanced Long Term Evolution，增强的长期演进)eNB(evolved Node B，演进基站)、LTE(Long Term Evolution，长期演进)eNB三中类型的基站，gNB为5G基站通过NG接口连接到核心网5GC(5G Core Network，第5代核心网)，LTE eNB为4G基站通过S1接口连接到核心网EPC(Evolved Packet Core，演进的分组核心网)，而eLTE eNB为4G到5G的过渡型基站可同时连接到核心网EPC(通过S1接口)和5GC(通过NG接口)。LTE eNB基站之间的连接接口称为X2接口，gNB基站之间的连接接口称为Xn接口，而eLTE eNB基站即可扮演LTE eNB基站的角色又可扮演gNB基站的角色。
在LTE(Long Term Evolution，长期演进)系统中，将具有相同QoS(Quality of Service，服务质量)要求的数据流聚合为承载，基站与核心网对QoS的处理都按承载进行。在5G系统中，将采用新的QoS机制以支持 eMBB(enhanced Mobile Broadband，增强移动宽带)、mMTC(massive Machine Type Communication，巨量机器类型通讯)、URLLC(Ultra Reliable and Low Latency Communication，高可靠低时延通讯)等5G特性业务。
在5G新的QoS机制下，一个UE(User Equipment，用户设备)可以建有多个PDU Session(Protocol Data Unit Session，协议数据单元会话)，一个PDU Session可以包含多个QoS Flow(Quality of Service Flow，服务质量流)。同一个PDU Session的多个QoS flow可以映射到同一个DRB(Data Radio Bearer，数据无线承载)，不同PDU Session的QoS flow(流)不可以映射到同一个DRB。
当在5G网络中进行DC(Dual Connectivity，双连接)操作时，一个UE的部分PDU Session和/或PDU Session中的部分QoS Flow可以从主基站分流到辅基站。然而、对于表示一个PDU Session的最大允许比特率的Session AMBR(Aggregate Maximum Bitrate，聚合最大比特率)和表示一个UE的最大允许比特率的UE AMBR如何在DC时进行分配与计算，目前尚没有具体方案。
针对相关技术中存在的上述问题，目前尚未发现有效的解决方案。
