Why this IMS course?
The IP Multimedia Subsystem, originally developed for UMTS, has become the IP services core of choice for telecoms systems in general. At its basic level, the IP Multimedia Subsystem is an architectural framework for delivering IP-based multimedia services.
One premise is to use IETF protocols wherever possible to ensure interfacing and compatibility with existing systems
- Each delegate receives a binder containing a copy of each slide with accompanying notes and a list of telecommunications acronyms.
Who should attend this IMS course
- This course is intended for anyone needing a detailed understanding of exactly how IMS works and its protocols. This includes, amongst others, planners, strategists, system engineers and designers.
IMS Course Pre-requisites
IMS is IP based so a basic knowledge of IP and its operation including topics such as DHCP, addressing and routing is assumed. There is no IP primer in the course.
Lifetime Post-Course Support
After completing this IMS training course, delegates receive lifetime post-training support from LEVER Technology Group, to help them apply the technologies and skills they have learned with us, to provide career-long support, and to ensure they are better equipped for their future roles in IT and networking.
