Common evolution of 5G network architecture deployment

1) Option2:
Standard 5G wireless network deployment architecture, only 5G NR and 5GC.

2) Option3/3a/3x :
Under the 4G current network condition, the core network is still EPC with the rapid deployment of 5G NR, and 5G NR supports S1/X2 interface to connect EPC and eNB.

3) Option4/4a
5GC and 5G NR are deployed in the network, and the eNB is enhanced to increase the N2/N3/Xn interface.

4) Option5 :
Enhanced eLTE access to 5GC.

5) Option7/7a/7X
5GC and 4G eLTE (enhanced LTE/eNB ) are deployed in the network, with 5GNR as auxiliary.

5G deployment scenario overall evolution line

1) Line A: Evolve to convergent 5GC through vEPC-NSA

• vEPC-NSA deployment based on cloud native supports evolution to 5GC.

• Quickly develop 5G services, but only some of the 5G features were implemented in the initial stage.

2) Line B: Directly introduce 5GC to realize network convergence

• Introduce 5GC in the initial stage, that can deploy the complete 5G characteristic.

• The initial impact on the existing network is less.

Major Global Operators’ considerations for the introduction of 5G

• Spectrum resources
• Less impact on existing network services
• Fast introduction of new business
• Low TCO
• Simplified network

Option 3(NSA)is chosen by Major Global Operators. Virtualization is the key step of 5G construction.
