相关申请的交叉引用
本申请基于申请号为201810273367.9、申请日为2018年03月29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引入本申请作为参考。
技术领域
本发明涉及但不限于通信领域，尤其涉及一种实现速率保证的方法、装置及存储介质。
背景技术
在相关技术中，第四代(4 Generation，4G)或者长期演进(Long Term Evolution，LTE)移动通讯系统中，4G基站称为演进基站(evolved Node B，eNB)，eNB之间的接口称为X2接口，eNB与核心网(Core Network，CN)之间的接口称为S1接口。
第五代(5 Generation，5G)移动通讯系统中，5G基站称为新一代无线接入网节点(New Generation Radio Access Network Node，NG RAN Node，又称为gNB)，gNB之间的接口称为Xn接口，gNB与CN之间的接口称为NG接口。
基站(eNB或gNB)和用户设备(User Equipment，UE)之间的接口称为Uu接口。
4G系统中，将具有相同服务质量(Quality of Service，QoS)要求的数据流聚合成承载，eNB与CN对QoS的处理都是按承载进行的，S1接口上的网络承载和Uu接口上的无线承载是1:1对应的。
5G系统中，采用了新的QoS机制，Uu接口上的无线承载概念仍然保 留即数据无线承载(Data Radio Bearer，DRB)，但NG接口上没有网络承载的概念，取而代之的是协议数据单元会话(Protocol Data Unit Session，PDU Session)和服务质量流(Quality of Service Flow，QoS Flow)。一个UE可以建有多个PDU Session，一个PDU Session可以包含多个QoS Flow，同一个PDU Session的多个QoS flow可以映射到同一个DRB，不同PDU Session的QoS flow不可以映射到同一个DRB。QoS flow包括：保证比特率服务质量流GBR QoS flow和非保证比特率服务质量流non-GBR QoS flow。
5G基站中，在分组数据会聚协议(Packet Data Convergence Protocol，PDCP)之上引入了新的业务数据适配协议(Service Data Adaptation Protocol，SDAP)用于QoS flow与DRB之间的映射(Mapping)等。每个PDU Session对应一个SDAP实体(Entity)，每个DRB对应一个PDCP实体。
5G基站可分为集中单元(Central Unit，CU)与分布单元(Distributed Unit，DU)两部分，一个基站有一个CU，一个基站可有多个DU，称为集中单元分布单元分离(CU DU Split)，CU与DU间的接口称为F1接口。
5G基站的CU可分为控制面(Control Plane，CP)与用户面(User Plane，UP)两部分，称为控制面用户面分离(CP UP Split)，CP与UP间的接口称为E1接口。
4G和5G系统中，均支持双连接(Dual Connectivity，DC)功能。双连接下UE可以同时与两个基站保持连接，其中一个基站称为主基站(Master Node，MN)，另一个基站称为辅基站(Secondary Node，SN)。
一种4G和5G混合组网的双连接称为演进通用陆地无线接入-新无线接入双连接(Evolved Universal Terrestrial Radio Access-New Radio Access Dual Connectivity，E-UTRA-NR DC/EN-DC)，EN-DC双连接下主基站为eNB，辅基站为gNB。
在4G、5G、4G/5G混合网络中(包括CU/DU分离、CP/UP分离的场 景)，针对UE在连接态、双/多连接时，相关技术中未能更好地实现速率保证，且在实现速率保证时，极大地浪费控制面信令。
