| 针对第五代移动通信网络双连接架构中承载分离算法执行时间间隔过长降低分离算法性能的问题，提出了一种基于用户终端协助的承载分离机制。通过构建用户满意度模型，实时计算用户对网络的满意度，根据终端的用户实时满意度和实际数据接收比向主基站发送终端的反馈消息。主基站根据用户的反馈消息及时调整承载分离比例和切换终端的连接模式。该机制可以与现有的承载分离算法相结合。系统仿真结果表明，相对于传统的承载分离算法，该机制能够提升10%的用户满意度；在通信系统负载较大时，能够提升10%的系统总吞吐量。 |

| Abstract: |
| For the problem that the execution time interval of bearer separation algorithm in 5G dual connection architecture is too long and the performance of separation algorithm is reduced,a bearer separation mechanism based on user terminal assistance is proposed.By constructing the user satisfaction model,the user satisfaction with the network is calculated in real time,and the feedback message of the terminal is sent to the main base station according to the user real-time satisfaction of the terminal and the actual data reception ratio.The master base station timely adjusts the bearer separation ratio and the connection mode of the switching terminal according to the users feedback message.This mechanism can be combined with the existing bearer separation algorithms.System simulation results show that compared with the traditional bearer separation algorithm,this mechanism can improve user satisfaction by 10%,and when the communication system load is large,it can improve the system throughput by 10%. |
