የሞባይል ዳታ ኔትዎርክ ስልጠና 3 | GPRS/UMTS Packet-Switched (PS) Technology Overview for 2G/3G Networks Part 3

This content provides a focused overview of GPRS/UMTS Packet-Switched (PS) technology in 2G and 3G mobile networks, with special emphasis on Radio Resource Management (RRM), the Paging Procedure, and Session Management.

It explains how the network efficiently allocates radio resources, locates mobile subscribers using paging mechanisms, and establishes, maintains, and releases packet data sessions. The material covers the interaction between key network elements such as MS, BTS/Node B, BSC/RNC, SGSN, and GGSN, helping engineers and students understand real-world PS traffic handling, mobility, and data session control in legacy mobile networks.

This is ideal for telecom engineers, NOC teams, students, and anyone preparing for mobile core network operations or optimization tasks.
This video presents a detailed overview of GPRS and UMTS Packet-Switched (PS) technology in 2G and 3G mobile networks. It covers the architecture of the PS core network, explaining key elements such as the SGSN, GGSN, RNC, Node-B, and the main interfaces between them. The video also explains critical network functions—including Mobility Management, Radio Resource Management, and Session Management—showing how mobile devices initiate, sustain, and control packet data services. This content is well suited for telecom engineers, students, and anyone looking to gain a solid understanding of packet-switched operations in legacy 2G/3G networks.
