Abstract: Methods for handling a data connection session in an Internet Protocol (IP) Multimedia Subsystem (IMS) network are provided. The method includes configuring a S50 interface between a Mobility Management Entity (MME) and a Policy and Charging Rules Function (PCRF) entity in the IMS network, and notifying a User Equipment (UE) about a Mobile Terminated (MT) Voice over LTE (VOLTE) call by using the MME. Another method includes configuring a SBI interface between an Access and Mobility Management Function (AMF) entity and the Policy Control Function (PCF) entity in the IMS network, and includes notifying a UE about a MT Voice over New Radio (VoNR) call by using the AMF entity.
