What is mobile core network?

The mobile communication network consists of three major parts: User Equipment (UE), Radio Equipment and Core Network (CN).
Three parts of mobile core network

Let' s learn more about mobile core network in this article. Basically, Mobile core network can be seen as the nervous system even the brain of a whole mobile telecommunications network, operating and managing the UE and radio equipment.

The evolution of mobile core network

2G/3G Core Network

The major part of 2G core network is Circuit Switched Domain (CS Domain) that can meet the requirement of calling.

In 3G era, Packet Switched Domain (PS Domain) is added for a new function to transmit network data.

4G Core Network (EPC)

While only PS domain remains in EPC architecture for Voice and SMS.

5G Core Network (5GC)

Based on the EPC architecture, Service Based Architecture (SBA) is introduced in 5GC that enables all core network elements to be deployed on cloud without the physical equipment.

The direction of evolution

1. Enhance the efficiency of transmission

  • Disaggregation of control plane and user plane
 

2. Improve the agility

  • The introduction of Service Based Architecture

    It evolves to a modular framework that supports multiple deployments for the requirements of diverse application scenarios.

 

3. Gain the flexibility

  • The introduction of Network Function Virtualization(NFV)
  • The virtualization of network node functions
  • The deployment on common hardware like X86
