摘要
随着5G技术逐步完善,端到端切片等新技术将助力5G语音业务实现。但在建设初期,受5G终端普及率低、网络覆盖不足、4G与5G长期共存等因素制约,如何低成本、高效率地部署5G网络,保障5G语音业务连续性,成为目前5G语音业务研究的热点课题。通过分析5G主流语音解决方案,结合4G现状讨论在建网初期将EPS Fallback作为5G语音解决方案的可行性。
With the gradual improvement of 5G technology,new technologies such as end-to-end slicing will help to realize 5G voice service. However,in the early stage of construction,restricted by the low penetration rate of 5G terminals,insufficient net- work coverage,long-term coexistence of 4G and 5G,how to deploy 5G network with low cost and high efficiency to ensure the continuity of 5G voice service has become a hot topic in the research of 5G voice service. Based on the analysis of 5G mainstream voice solution and the current situation of 4G,the feasibility of using EPS Fallback as 5G voice solution in the initial stage of network construction is discussed.
