Abstract
With the evolution of the core network, providing multimedia services is much easier in the all-IP - networks than that in the - networks. In the 4G/5G core network, the (IMS) is widely deployed to provide multimedia services such as (VoLTE). To provide a fair-competition environment for the mobile operators, the (NP) service should be defined in the 4G/5G specifications. However, the up-to-date specifications only indicate that the (ENUM) can be used for the NP service but do not propose the detail message flows and the major parameters. Moreover, the NP scenarios in the IMS networks are different from those in the (PSTNs). To provide the NP service in 4G/5G, this paper proposes an ENUM-based NP service where the message flows and the major parameters are designed based on the IMS architecture.
