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.


Suggestion on the Evolution of 5GC

a) 5G introduction phase: in 2017 ~ 2018
vEPC construction
• EPC NSA trial
• 5GC trial

In 2018 ~ 2019
• EPC NSA Commercial
• 5GC IoT & trial
• Build a unified telecommunications cloud resource pool for 5G target networks

b) 4G and 5G coexistence stage: in 2019 ~ 2020
• 5GC small-scale commercial use
• 5GC full converged access capability

c) 5G main stage: in 2020 ~ 2022
• 5GC large-scale commercial use
• New operations, new business

Evolution Routing of 5G deployment  

a) Option1→Option2

b) Option1→Option3→Option2

c) Option1→Option3→Option7→Option2

d) Option1→Option3→Option4→Option2

e) Option1→Option3→Option7→Option4→Option2


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.
