5G上行带宽探测与应用研究

提出了一种5G上行带宽探测与应用的方案，能够有效解决视频监控数据在5G网络传输过程中遇到的网络波动问题，助力5G视频监控应用的实际落地部署。该方案在终端侧获取5G基站的无线资源调度信息，通过统计传输资源，估算出上行带宽变化趋势，结合流媒体应用的智能编码技术和码流自适应技术，在损失一定视频清晰度的代价下，保证视频不卡顿、画面连续，保障客户的整体感知。该方案可以广泛应用在校园视频监控等5G公共业务多、网络波动大、覆盖范围广的场景。

Research on 5G upstream bandwidth detection technology and application

A scheme of 5G upstream bandwidth detection technology and application was proposed, which could effectively solve the problem of 5G network fluctuation in video monitoring data transmission process.It will help the deployment of 5G video monitoring application.By obtaining the radio resource information of 5G NR, the terminal can count the transmission resource and estimate the change trend of uplink bandwidth.Combined with the intelligent coding technology and bit-stream adaptive technology of streaming media application, the scheme ensures no stuck and continuous picture at the cost of losing a little video definition, and ensures the overall experience of customers.The scheme can be widely used in the scene of heavy 5G public service, large network fluctuation and wide network coverage, such as campus video surveillance.
