südamikuvõrk

Südamikuvõrk refers to the core network infrastructure of a telecommunications system, particularly in mobile networks. It is the central part of the network that connects various parts of the mobile network and provides essential services such as call routing, data transfer, and mobility management. The südamikuvõrk acts as the backbone, enabling communication between different base stations and the wider internet or other public switched telephone networks.

This core network is typically comprised of several key components. These include mobile switching centers (MSCs) which handle voice calls and circuit-switched data, and gateway GPRS support nodes (GGSNs) and serving GPRS support nodes (SGSNs) which manage packet-switched data services. Databases such as the home location register (HLR) and visitor location register (VLR) are also crucial, storing subscriber information and managing user location to ensure seamless service.

The evolution of mobile technology, such as the transition from 2G to 3G, 4G, and now 5G, has seen significant changes and upgrades to the südamikuvõrk. Newer generations introduce more advanced architectures, like the Evolved Packet Core (EPC) in 4G and the 5G Core (5GC), which are designed for higher speeds, lower latency, and greater capacity, supporting a wider range of services including IoT and enhanced mobile broadband. The südamikuvõrk is vital for the overall performance, reliability, and scalability of any mobile telecommunications service.
