In 5G non-standalone, emphasis is on a gradual roadmap from 4G to 5G mobile network. This course focuses on path migration of 2G, 3G to 5G mobile networks, considering timelines and technology used in each generation of mobile communication. The full description of the mobile networks as listed on the course title may not be covered in detail. The course starts with the background of RF mobile networks, then it gives insight about the fundamentals of mobile networks, the evolution from 1G which was Analog in nature, to the global system for mobile communication (2G) in digital format and employing circuit switched (voice) and the variants (GPRS) for limited data and to 3G when the packet switched network was utilized. This developments hereafter, paved way for video calling, live streaming, mobile internet access, IPTV, etc. The course presents the standardization landscapes as defined by 3GPP, focusing on the sequence of Releases of the standards in migration towards 5G. The sessions of the course also describe the network architecture of each generation of mobile communication. Also covered in this course are the 3GPP cellular telecommunications technologies including radio-access, core network and service capabilities which provide a complete system description for mobile telecommunication. Con sequently, with the emergence of Long-Term Evolution (LTE) Network, the core network, Evolved Packet Core (EPC) is an all-IP core network and is fully Packet Switched (PS). Services like voice, which are traditionally Circuit Switched (CS), will be handled using the IP Multimedia Subsystem (IMS) network. The LTE-Advanced (LTE-A) was introduced as enablers to enhance the performance of the network. As a result, the theoretical data throughput offered by the LTE-A is up to 3Gbps (Giga bits per second) data rate â a significant improvement over LTE. In LTE-A Pro, further enhancement was carried out, using full dimension MIMO (FD-MIMO) and Vertical beamforming to target LTE enhancements towards Machine-Type-Communications. This course is pace-enabled with interactive sessions. As we trace the Path of migration towards 5G, we shall demonstrate by diagrams the architecture of each of the mobile networks and use the Samsung case study as one methodology to explain real-life scenario.
This course is tailored to make references to 3GPP Technical Specifications and standards from a practical analysis and interpretation of such documentation. The course is targeted at managers, engineers and employees from regulators, government organizations, telecommunication companies, IT industry, and academia, who are interested in understanding the Path migration of 3G mobile communications to 5G mobile network non-Standalone. Other individuals and institutions that are dedicated to building or enhancing their capacity related to 5G mobile network, emerging technologies, and beyond should find this course useful.
No prior knowledge or qualification is required to register for this course, considering the given target population.
Upon completion of this course, participants will be able to:
Explain the evolution of Mobile networks in succinct manner (i.e., difference in data rates and speeds the networks);
Identify the key elements of 3G, LTE, LTE-A, LTE-A Pro, and 5G Non-Standalone mobile networks;
Identify enhancement requirements/parameters (i.e., latency, frequency bands, modulation techniques, capacity of the network, etc.) for migration from 3G to 5G;
List and describe major key features in 5G mobile network;
Evaluate from the mobile network applications and use cases the User-experience of the networks.
The training involves synchronous live sessions by subject matter experts, recorded class videos, electronic course manuals, assignments, online assessment and case study scenarios for synchronous live sessions.
The course (2 weeks duration) study method is the following:
Course Materials: The relevant course material (Presentations) and pre-recorded video is made available on the ITU Academy learning portal at the beginning of the course to facilitate self-study. Each week is based on 2 hours of lectures-presentations per week.
Online Discussion Forums: discussion forums are organized weekly at the ITU Academy based on discussions topics and case studies. Students are highly encouraged to participate and interact with instructors and other students (e.g., forum participation, Moodle messenger, etc.).
Chat Sessions: weekly live chat sessions via Zoom platform (2pm CEST) with the students to facilitate questions about the material covered for the week and the assignments. The dates for the live chat session(s) will be communicated to participants on the first day of the course.
Quizzes: One mandatory online quiz (i.e., multiple choice questions) at the end of each week.
Assignment. A downloadable Word document Template is provided for submission case study research assignment on the ITU Academy.
The participants are evaluated according to their substantive posts on the discussion forum, active participation in the online chat sessions, reflecting both the quantity and quality of time spent on the course. Two quizzes at the end of each week (i.e., week 1 and week 2), and one individual assignment to be submitted and graded. Templates outlining the format for the assignment submission are provided on the ITU Academy platform. Each quiz has multiple choices questions. The maximum grade for the course is 100 points. The evaluation details and criteria for earning certificates are as follows.
A total score of 70% and above is required to obtain the ITU course completion certificate, through the following evaluation parameters:
Two quizzes 50%
Individual Assignment 20%
Two Chat Sessions 15%
Two Discussion Forums 15%
