| 摘 要: 针对目前电信运营商5G基站分布不均匀及5G SA模式基站覆盖效果有限的问题，提出通过多路径数据传输协议(MultiPath TCP, MPTCP)与5G技术相结合的方案，聚合不同运营商的5G通信链路，提高5G在应用场景中的传输带宽、连接鲁棒性及网络服务质量。针对该方案，设计基于5G的多路径数据传输系统；该系统以I.MX6ULL作为主控制器，通过两个5G模组完成数据传输，采用局域网与外部终端完成数据交互，USB串口作为控制终台。测试结果表明：系统使用MPTCP协议通过两条5G通信链路进行数据传输的传输速率比单条链路的传输速率提高了一倍左右，并且系统稳定性也明显提高，能够达到既定目标的链路聚合效果，具有较高的实用价值。 |

| Abstract: In view of the uneven distribution of 5G base stations of telecom operators and the limited coverage effect of 5G SA mode base stations, a scheme combining multipath TCP (MPTCP) with 5G technology is proposed to aggregate 5G communication links of different operators to improve the transmission bandwidth, connection robustness and network service quality of 5G in application scenarios. For this scheme, a multipath data transmission system based on 5G is designed. With I.MX6ULL as the main controller in this system, data transmission is completed through two 5G modules; data interaction between LAN (Local Area Network) and external terminals is completed with USB serial port as the control terminal. The test results show that the data transmission rate of the system using MPTCP protocol through two 5G communication links is about twice as high as that of a single link, and the system stability is also significantly improved, which can achieve the link aggregation effect of the established goal, and has high practical value. |
