IP Multimedia Subsystem (IMS)


The IP Multi-Media Subsystem (IMS) is an IP multimedia and telephony core network. It is defined by 3GPP and 3GPP2 standards and organizations based on IETF Internet protocols. IMS is access independent as it supports IP to IP session over wireline IP, 802.11, 802.15, WiMAX, CDMA, GSM/EDGE/UMTS and other packet data

applications. IMS permits and enhances real time, multimedia mobile services such as rich voice, video telephony, messaging, conferencing and push services by responding to the emerging trend to move toward a common, standardized subsystem. As data services proliferate and the value chain expands, current vertical application platforms are proving

insufficient to meet operator needs. IMS represents a standardized, reusable platform providing a better

way to experiment with, deploy, integrate, and expand consumer and enterprise voice and data services. This course provides an advanced technical overview of IMS. In this course we will discuss various advanced

concepts that are integral to the development of IMS and all IP networks.

After completing this course, students will be able to:

Understand concepts behind All-IP Multimedia Networks

Understand IMS architecture

Explain IMS reference architecture

Understand IMS session control and

connection control

Explore SIP and SDP extensions used in IMS

Explain IMS services

Understand IMS Security and QoS

Who Should Attend

This course is designed for strategic or technical

managers, consultants, communications professionals, software engineers, system engineers, network professionals, marketing and sales professional, IT professionals, and others who plan on using, evaluating or working with IMS.

Mobile Advertising


Most mass-media channels – newspapers, TV, Internet – heavily rely on revenues from advertisers, rather than from end-users. The mobile world has recently started shifting its revenue model from user-based revenues to ad revenues. Furthermore, the mobile channel is the advertiser’s

dream – always with the user, media-rich, variety of channels (e.g. SMS, MMS, WAP, Idle, Voice), and it is the most personalized device. Advertisers are seeing the great potential in mobile advertising, and are shifting budgets from other advertising methods to mobile advertising. Mobile advertising is estimated to exceed 20 Billion USD by 2013.

Mobile advertising should interest any vendor of

mobile equipment in layer 4 and above, as it constitutes a significant portion of the traffic on one hand, and encompasses a business opportunity on the other hand. For the same reasons, mobile advertising should

also interest providers of mobile content, mobile applications and any service provider who has a mobile strategy. The course provides an overview of the mobile advertising value-chain, business models, technologies, standards and market players.

After successfully completing the course the students will:

Be familiar with opportunities in mobile advertising for equipment vendors, service providers, and any organization with a mobile strategy.

Recognize the business and technological roles and relationship of the variety of entities within the mobile advertising value chain, and be able to approach relevant entities.

Understand the technologies and products taking place in delivery of mobile advertising and monetization thereof, in the different

channels – SMS, MMS, WAP, HTTP, Idle, Voice, Push, Gaming etc.

Know the standards associated with mobile advertising, mainly MMA, as well as de-facto standards gaining grounds.

Be able to define a mobile advertising strategy for their organizations, and assess the operational (R&D, BD etc.) steps

required to realize this strategy.

Who Should Attend

The course is relevant for the following organizations:
