The course uses a top-down approach starting with a high level description of the functionality of different network entities and the interaction needed between on different interfaces. The layer 3 protocols are then discussed one by one in detail in a logical scenario-based sequence. A number of detailed message-by-message signalling sequences will be presented during the course to tie everything together. Protocols and signalling procedures related to the 5GC-internal Service Based Architecture are mentioned but not covered in any detail.
This course provides a thorough overview of the Next-Generation Radio Access Network (NG-RAN) which is part of the 3GPP 5G System. The focus is on Stand-Alone (SA) operation but also Non-Stand Alone (NSA) NR is outlined. The course starts with a brief introduction to the 5G System, followed by a discussion of aspects of the new radio interface and the nodes, interfaces and procedures in the NG-RAN. The course also describes various RAN – core option and dual connectivity options as well as some NG-RAN implementations such as C-RAN, O-RAN (from O-RAN Alliance) and IAB (Integrated Access and Backhaul).
The SS7 Signaling in Mobile Networks course explains and describes the world’s most widespread inter-exchange signaling system used in fixed and mobile telecommunication today: Signaling System No 7. It provides the basic ideas and structure of the SS7 protocol stack. Different aspects of various signaling protocols and signaling applications in the telecommunications world are covered. There are a few detailed examples from both mobile and fixed networks. The course focus is on ITU SS7 and GSM/UMTS core network protocols that are based on SS7 system. The participants will also gain a general understanding of how to interpret log files and traces taken from live networks.
LTE, or strictly speaking the Evolved Packet System (EPS), consists of the evolved Radio Access Network (E-UTRAN) and the Evolved Packet Core (EPC) as defined in 3GPP technical specifications. The course focuses on the network architecture, nodes and mode of operation of the entire LTE System. It accounts for interfaces, protocols and services provided by LTE, including Mobile Broadband, VoLTE and IoT. Message-level traffic cases are used throughout the course to demonstrate important functions and concepts.
This course explains the basic functions in TCP/IP. The focus on this training is set on the protocols within the architecture TCP/IP. The purpose is to make the participants understand what the different protocols do and to have knowledge of other important functions such as routing and DNS. TCP/IP is a technology used in computers all over the world. This course will give you the fundamental TCP/IP knowledge in order to be able to attend other specific courses in areas such as routing technology, VPN, realtime-IP, QoS and IT-security.
The 5G System Overview provides an overview of the emerging 5G system as defined and standardized by 3GPP, other SDOs (standard development organizations) as well as various industry players and initiatives. The course accounts for the various aspects of the 5G System (Access Network, 5G Core), nodes/functions, interfaces / reference points, basic procedures and main architectural ideas. The course explains concepts important to 5G like NFV/SDN and network slicing, and how these are used to make the 5G System more efficient and flexible than earlier generations of 3GPP networks. The ITU 5G Use Cases (eMBB, URLLC and mMTC) are outlined in terms of services and technical aspects. The course gives an overview of the 5G Radio Access Network including 5G New Radio (NR) and integration with LTE.
This fiber optic course is designed for anyone interested in becoming a Fiber Optic Technician. This Fiber Optic Training combines theory and hands-on activities to equip student to work with optical fiber. This course also introduces the student to industry standards governing FTTD (Fiber to the Desk), FTTH (Fiber to the Home), and Distribution Cabling.
This five days course will help you to thoroughly understand all the issues of using and building a Voice over IP Network. We will cover the reasons for using the VoIP technology and we will cover the fundamental of the signaling protocol SIP. SIP is certainly an extensible protocol but all the details are moved to the course SIP Advanced. Already in this course, you will get the fundamentals and a good view into SIP and a good understanding regarding its possibilities. After this training, the students will understand the basic mechanisms of SIP they will also get a good platform for further studies into SIP, such as the course SIP Advanced.
