This course provides a detailed technical description of the currently specified methods of offering a voice service via LTE.
Who would benefit
This course is suitable for engineering and technical management staff who require a technical description of the options that exist in LTE 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.
Topic areas include
- Technical overview of LTE
- Introduction to the options for LTE voice
- CS fallback architecture and protocols
- CS fallback attach and call setup procedures
- Technical overview of the IMS
