Research on Reinforcement Measures For Voice Services in 5G Core Network

VoNR service of telecom operators involves 5G core network and IMS network, and there are many network elements involved in the realization of the service. IMS network, as the main provider of mobile voice service, has been deployed in scale as early as in the 4G era, and its development is relatively mature. In contrast, the 5G core network has been deployed for a short period of time, and the existing network application needs to be improved in many areas. This paper mainly focuses on voice services and discusses the measures needed to strengthen the $\mathbf{5 G}$ core network.
