Course Code: LT1602
This course provides a detailed technical description of the architecture and operation of the IP Multimedia Subsystem, and its use for the delivery of a VoIP service over LTE.
This course is suitable for engineering and technical management staff who require a technical description of the options that exist in LTE and the IP multimedia subsystem for delivering voice and other real-time traffic types, that would traditionally have been carried by Circuit-Switched (CS) technologies.
Attendance on this course assumes previous attendance on the LTE Engineering Overview course (LT3600) or equivalent basic LTE knowledge (although a recap of basic LTE architecture and concepts is provided at the start of the course) and also assumes a working knowledge of IP.
