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.
Objectives
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.
