Students who have successfully finished this module have an overview of current and future services and service infrastructures in the Mobile Internet. They have developed an understanding of the special characteristics of mobile networks - compared to fixed infrastructures - and have learned about the benefits of mobile services and the fascinating prospects of emerging areas such as Location-based Services and Ubiquitous Computing. However, they are also aware of the problems and limits of mobile service provisioning and know how to cope with these deficiencies when designing them. Furthermore, they have good knowledge of different alternatives of realizing services (for example, device versus network centric approaches) and an overview of related service platforms, auxiliary functions, and operating systems of mobile devices.

The module starts with a brief introduction into the fundamentals of mobile networks and an overview of related infrastructures of GSM, UMTS, LTE and other networks. This includes a short discussion about the particular problems these networks imply and a general overview of the special features they offer, for example, regarding the different types of mobility support and associated mechanisms. After that, the module introduces different service platforms and infrastructures and demonstrates their realization and operation. The following services and service platforms are covered:

• Mobile cellular networks
• SMS und MMS
• Mobile Internet
• IMS/SIP services
• Advanced Services (Mobile Instant Messaging)
• Location-based Services
• Positioning Services

The module concludes with an overview and discussion of latest trends and developments.
