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.

Abstract: A method for managing an operation of a wireline access gateway function (W-AGF) in a wireless network is disclosed. The method comprises transmitting, by a W-AGF control plane (W-AGF-C) entity of the W-AGF to a W-AGF user plane (W-AGF-U) entity of the W-AGF, a performance statistics request message for at least one object; and receiving, by the W-AGF-C entity from the W-AGF-U entity, a performance statics response message in response to the performance statistics request message.

Abstract: A method for optimizing an internet protocol (IP) multimedia subsystem (IMS) packet data network (PDN) connection, includes: establishing, by a user equipment (UE), an IMS PDN connection and an internet PDN connection with at least one data network element of a communication network, wherein a primary IP address corresponding to the IMS PDN connection and a secondary IP address corresponding to the internet PDN connection are allocated to the UE by the at least one data network element; sharing, by the UE with an IMS, the secondary IP address over the internet PDN connection, before disconnecting the IMS PDN connection by the communication network; receiving, by the UE from the IMS, a mobile terminated (MT) call notification using the secondary IP address over the internet PDN connection; and based on the received MT call notification, re-establishing, by the UE, the IMS PDN connection.
