The Final Exam will be given out IN CLASS on Wednesday, December 6. Due Friday, December 8.

Competition Proposals are due November 27!

This course provides an introduction to the IP Multimedia Subsystem (IMS) and covers the process of developing an application for IMS. 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 will ultimately decide to enter 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.
