Planning the UMTS core network consist of GSN (GPRS Service Node) system design, MSC and registers
dimensioning, OMC dimensioning, Core network interface dimensioning.
The Core Network has several interfaces, which need to be configured and dimensioned. The Core Network hardware
configuration is also vendor specific. Network vendors have very extensive documentation how to design all aspects
of core network starting from the room environmental requirements up to the post integration system quality audit.
The course covers the details of various functions of the Core Network including Mobility Management, authentication,
security, roaming, call and session setup and evolution of the UMTS network towards an all-IP based network. |

After successfully completing the course the student will:
- Understand the purpose of implementing packet switching in the existing GSM system
- Know how the UMTS architecture looks like
- Know what the core network looks like in UMTS as well as the architecture.
- Understand the evolution of the Core Network from GSM/GPRS over UMTS R99 and R4 towards
the "All-IP" of R5 and R6
- Understand the UMTS network infrastructure and components
- Learn the requirements and operation of a UMTS Core Network, and the fundamentals of the
"3G All IP" network
- Understand CAMEL, MEXE and their role within the Virtual Home Environment
- Understand in depth ATM ( Asynchronous Transfer Mode), AAL structures, and VoIP. and their
role within UMTS
- Learn the new 3G signaling protocols, transport, control and user planes etc.
- Understand 3G-MAP, UDP/IP and TCP/IP and their roles within 3G
- Understand how Call transactions are constructed and executed
- Undestand the enabling technologies such as SIP, MEGACO and IPv6 and the use of these technologies
within All-IP Multimedia architecture
- Become familiar with the network evolution towards 4G
- Understand how the network can support the implementation of new services, the impact that
these services will have on the network including the security, charging, and quality of service considerations.
