Why choose TONEX for your IMS Training?

IMS Training  (IP Multimedia Subsystem applied to VoLTE) covers various basics and advanced IMS concepts that are integral to the development of IMS in UMTS, LTE and other networks. SIP, Diameter, Voice over LTE (VoLTE).

Through hands-on exercises with WIreshark and an LTE UE, students will see how IMS has been implemented in LTE network used for voice, SMS, MMS and other services.

The IP Multimedia Subsystem (IMS) defines the functional architecture and requirements for a managed IP-based network. It is an open, standards-based network that delivers integrated multimedia services to service providers.

IP Multimedia Subsystem (IMS) is one of 3GPP’s greatest success stories.

Originally designed to evolve UMTS networks to deliver Internet Protocol multimedia to mobile users, IMS has become the core component within 3G, cable TV and next generation fixed telecoms networks.

IMS Training

IMS specification began in 3GPP Release 5 as part of the core network evolution from circuit-switching to packet-switching and was refined by subsequent Releases 6 and 7.

Initially, IMS was an all-IP system designed to assist mobile operators deliver next generation interactive and interoperable services, cost-effectively, over an architecture providing the flexibility of the Internet.

You will learn key IMS concepts including protocols: SIP, SDP, H.248, COPS, and Diameter. Learn about IMS component is and their functions.
