5G System Connection Management: CM-Idle and CM-Connected
When a Mobile wants to communicate with 5G core network, as it first time switched-on or because it was in idle state for some time and network removed the resources […]
What is Cloud Computing
Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. The term is generally used to describe data centers available to many users over the Internet. […]
5G Network Sharing: Concept, Benefits and Architectures
The deployment of a new telecommunication network and its operation can lead to very high costs and a long entry time to business for a operator. Sharing the network infrastructures […]
What is NUMA (non-uniform memory access)?
In the past, processors had been designed as Symmetric Multi-processing or Uniform Memory Architecture (UMA) machines, which mean that all processors shared the access to all memory available in the system over the single […]
5G NR Global Unique Temporary Identifier (GUTI)
5G Global Unique Temporary Identifier [5G – GUTI] is a core network temporary identifier and allocated by Access and Mobility Management function [AMF] to the UE. GUTI is 80 bits […]
5G NR Grant Free Dynamic Scheduling – Transmission without Grant (TWG)
5G networks are expected to support applications demanding ultra-reliable and low latency communication services (URLLC). To support these kind of applications 5G-NR introduced grant free uplink transmission feature a.k.a. Transmission […]
