Mobile Services are usually offered over mobile communication networks such as UMTS and LTE and are requested from mobile devices like ordinary mobile phones, smartphones, tablets 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 continues with an overview of related infrastructures of GSM, UMTS, LTE, 5G, WLAN, Bluetooth 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:

• 3GPP Networks (GSM, GPRS, UMTS, LTE, 5G)
• Non-3GPP Networks (WLAN, Bluetooth, etc.)
• SMS and MMS
• Mobile Internet (Mobile IP)
• IP Multimedia Subsystem
• Location-based Services
• Positioning Techniques (GPS, Cellular Network-based, Fingerprinting, etc.)

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, MSc.)
• Computer Engineering (Technische Informatik, MSc.)
• ICT Innovation (MSc.)
• Business Informatics (Wirtschaftsinformatik, MSc.)

To register for an oral exam, it is first required to pre-register. The pre-registration form is open until April 28, 2022 at 23.59 o'clock.

Number of oral exams in summer term 2022 is strictly limited to 60. 

In case more than 60 students want to pre-register for an oral exam, a selection process with waiting lists according to AllgStuPO § 36 will be applied. The selection process is not conducted on a first-come first-serve basis. See AllgStuPO § 36 for more details. Pre-registered students will be notified via email until May 4, 2022 whether they can finally register for the oral exam (via MOSES) or are put on the waiting list. Pre-registration is obligatory in order to get into the selection process. Without a pre-registration, a registration for the oral exam will not be possible.

More details about the exam registration process will be announced during the first lecture on April 20, 2022.

The oral exams are conducted at the end of the summer term between September 19-28, 2022. Each oral exam lasts between 20 and 25 minutes. Each student is examined individually. Whether the oral exams are conducted with physical presence or remote depends upon the COVID-19 situation at the end of September.

An oral exam is rated as failed in case of absence without valid excuse. This does not have an impact on possibly contradicting rules of the respective examination regulation.
