IMS Training Course is designed for both engineers and non engineers.

IMS Training Course, provides an advanced technical overview of IP Multimedia Subsystem (IMS). In this course we will discuss various advanced concepts that are integral to the development of IMS and all IP networks.

IP MultiMedia Subsystem (IMS) is an IP multimedia and telephony core network. It is defined by 3GPP and 3GPP2 standards and organizations based on Internet protocols. IMS is access independent as it supports IP to IP session over wireline, cable, EV-DO, HSPA/HSPA+, LTE, VoLTE and other packet data applications.

IMS Training Course

IMS permits and enhances real time, multimedia mobile services such as rich voice, video telephony, messaging, conferencing and push services by responding to the emerging trend to move toward a common, standardized subsystem.

As data services proliferate and the value chain expands, current vertical application platforms are proving insufficient to meet operator needs. IMS represents a standardized, reusable platform providing a better way to experiment with, deploy, integrate, and expand consumer and enterprise voice and data services.
