技术领域
本文涉及但不限于移动通信技术,尤指一种实现数据处理的方法、网元及系统、存储介质。
背景技术
在长期演进(LTE,Long Term Evolution)移动通信系统中,将具有相同服务质量(QoS,Quality of Service)要求的数据流聚合成承载,无线接入网(RAN,Radio Access Network)与核心网(CN,Core Network)对QoS的处理都是按承载进行的。图1为相关技术中长期演进移动通信系统的结构框图,如图1所示,在LTE系统中,RAN包括演进基站(eNB,evolved Node B)与用户设备(UE,User Equipment)。eNB与核心网间S1接口上的网络侧承载和eNB与UE间空口上的无线承载为1:1关系。
目前,正在研究的下一代移动通信技术中,第五代移动通信技术(5G,the 5th Generation mobile communication),其网络吞吐量为LTE系统的1000倍、设备连接数为LTE系统的100倍、低时延的性能提升为LTE系统的10倍。因此,包括5G在内的下一代系统要求具有新的更好的QoS机制。
下一代系统将采用一个统一的技术架构来支持增强移动宽带(eMBB enhanced Mobile Broadband)、巨量机器类型通讯(mMTC massive Machine  Type Communication)、高可靠低时延通讯(URLLC,Ultra Reliable and Low Latency Communication)等业务。在下一代的移动通信系统中,核心网、基站和UE都会做重大演进;图2为5G移动通信网络的结构框图,如图2所示,5G基站称gNB,类似于4G系统eNB间的X2接口,gNB之间的接口为Xn接口;gNB与5G核心网间的接口称为NG接口。5G系统中,一个UE可以建有多个协议数据单元会话(PDU Session,Protocol Data Unit Session),一个PDU Session可以包含多个服务质量流(QoS Flow,Quality of Service Flow),同一个PDU Session的多个QoS flow可以映射到同一个数据无线承载(DRB,Data Radio Bearer)。不同PDU Session的QoS flow不可以映射到同一个DRB。在5G基站中,将在PDCP之上引入一个新的接入层(AS,Access Statum)协议层(比如称作分组数据关联协议(PDAP,Packet Data Association Protocol),用于协调新的QoS机制在AS层的新功能,每个PDU Session有一个PDAP实体。5G基站可以分为集中单元(CU,Central Unit)与分布单元(DU,Distributed Unit)两部分;一个基站可以包含一个CU和多个DU。
针对下一代移动系统中新的QoS机制等特性,目前,尚未提出对系统中包括数据分流与切换等数据处理方法。
