Mobile Services (ST 2015)

• The ISIS course is online now: https://isis.tu-berlin.de/course/view.php?id=4833 [1]
• Due to a collision with another compulsory course we had to change the day and time of the second lecture. Please notice that we changed the date to Wednesday between 12 noon and 2pm.

Mobile Services are usually offered over a mobile communications network like UMTS and requested from mobile devices like ordinary mobile phones, smartphones, or laptops. Compared to conventional information and communication services as known from the Fixed Internet, Mobile Services are exposed to several restrictions, for example, limited bandwidth and increased latency, reduced computational power and memory of mobile devices, changing network addresses as a result of the users’ mobility, and many more. On the other hand, however, they open up a broad range of new and sophisticated applications in areas such as navigation, context-awareness, or ubiquitous and pervasive computing, to name only a few.

The module starts with a brief introduction into the fundamentals of mobile networks and an overview of related infrastructures of GSM, UMTS, 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:

• SMS and MMS
• Mobile Internet
• Marketplaces (iPhone, Android)
• IMS services
• Advanced Services (Mobile Instant Messaging)
• Location-based Services
• IP Multimedia Subsystem

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

This course is offered as compulsory course (Wahlpflichtfach) to master and diploma students of the following programs:

• Computer Science (Informatik)
• Computer Engineering (Technische Informatik)
• ICT Innovation
• Business Informatics (Wirtschaftsinformatik)

This module is limited to 50 participants. We register you – the self-enrollment via QISPOS is deactivated. Some majors accept this course in several study areas/pillars (computer engineering, business informatics, etc.). The system doesn’t allow the assignment to a specific study area/pillar. If this affects you, this means: We still register you, but after finishing this course you have to go the examination office and move this course to your preferred area/pillar. Exception: if you want to have this as an additional course, e.g. extracurricular studies (Studium Generale) or carry over to master studies, then register via a Yellow Page (“Zusatzmodul”). 

All students need to clarify for themselves if they can use the credits in their TUB subjects.

An oral examination is offered, which lasts between 20 and 30 minutes. The examination is rated as failed in cases of absence without valid excuse. This does not have an impact on possibly contradicting rules of the respective examination regulation.
