This course provides a hands-on laboratory experience for developing applications for the IP Multimedia Subsystem. The IP Multimedia Subsystem (IMS) is the next-generation standard in telecommunications network architecture, enabling a leap forward for voice, video, data, and multimedia applications. Telecommunications companies will soon use IMS technology to offer new services that subscribers can access from any location on a wide variety of devices. The students in this class will learn to design and develop these new services.

This class is being taught in conjunction with the ongoing IMS research competition. We anticipate that many students in this class are currently participating in the competition. However, participation in class is not tied to the competition. You do not have to enter the competition to take the class. You do not have to take the class to enter the competition. We anticipate that we will meet in the classroom almost every Monday during the semester. However, most weeks we will not meet as a class on Wednesday but will instead expect you to spend time in the lab working on your assignments.
