EPS FB完成后无法快速返回5G的对策研究

Research on Countermeasures for the Inability to Fast Return to 5G after EPS FB is Completed

随着NR SA网络的建设,城区主要区域已经完成SA连续覆盖。在4G通话结束后,如何快速返回5G,保证用户对数据和语音的良好体验,是当前需要重点解决的问题。因此,分析无法返回5G的问题,提出了基于四阶定位法的EPS FB完成后无法快速返回5G的排查策略,并在主城区进行测试验证。实验结果证明,按照相应的策略进行定位与排查,使运城市FR快速返回成功率从94%提升到99%,并且相应的技术在全省范围进行推广取得了较好的效果。

With the construction of the NR SA network,SA coverage has been completed in the main urban areas.After the 4G call is over,how to quickly return to 5G to ensure a good user experience of data and voice is a key issue that needs to be resolved.Therefore,the problem of failing to return to 5G was analyzed,and the EPS FB based on the fourth-order positioning method is proposed to be able to quickly return to 5G after the completion of the troubleshooting strategy,and the test verification is carried out in the main urban area.The experimental results prove that the positioning and investigation according to the corresponding strategy has increased the success rate of the rapid return of the FR in Yuncheng from 94%to 99%,and the corresponding technology has been promoted across the province and achieved good results.
