摘　　要：5G通信和新能源汽车迅猛发展的今天,弱网问题、断网问题严重影响着车辆联网功能,例如视频、音乐不能播放,同时需要保障车辆在有网络的条件下安全行驶。根据3GPP标准,文章提供了网络复归、自适应切换网络频段互操作两种策略,通过对通信模组进行锁4G、CFUN切换、重启以及寻找最佳通信网络频段,可快速恢复稳定的网络环境,使车辆在稳定网络状态下提供服务,提升用户体验。In the era of rapid development of 5G communication and new energy vehicles,weak network and disconnection issues severely affect the vehicle's connected functions,such as the inability to play videos and music.At the same time,it is essential to ensure that vehicles can safely operate under conditions with network access.According to the 3GPP standards,two strategies are provided:network recovery and frequency band adaptive strategy.By locking the communication mod⁃ule to 4G,CFUN switching,restarting,and searching the best communication network frequency band,a stable network environment can be quickly restored,allowing the vehicle to provide services under a stable network state and enhancing the user experience.
