3. Features to evolve Network Architecture 01

4. Several features have been suggested within Network Architecture, when Mobile Network evolves along the way from 2G, 3G, 4G, to 5G : Macro Cell grows smaller and smaller; Cell goes into building, goes into Indoor with less transmission power; Frequency Plan gets more intelligent; Wireless Network Standards get closer to WiFi Network, proposed by US The introduction of Pico Cell into Network, would better improve subscriber’s experience, which prompts a layer of 4G Pico-Cell Network Standards, by ITU. I. Network Architecture Evolution for Mobile Network Growing Features

5. I. Network Architecture Evolution for Mobile Network 2G Network Architecture 2G Network Architecture takes shape of structure in three levels, that is, BTS-BSC-MSC, which includes both CS and PS domain

6. I. Network Architecture Evolution for Mobile Network 3G Network Architecture 3 G Network Architecture also takes shape of structure in three levels, that is, Node B-RNC-Core Network, which includes both CS and PS domain

7. I. Network Architecture Evolution for Mobile Network 4G Network Architecture 4G Network Architecture takes shape of flattening structure, to reduce 3 levels into 2 levels, eNode B-Core Network. Among those RNC functions, some of which have been shifted into eNode B, the others have been added into Core Network. Only PS domain is severed.

8. I. Network Architecture Evolution for Mobile Network 5G Network Architecture 5G Network Architecture comes back to three levels of structure, that’s, DU-CU-Core Network (5GC). DU and CU constitutes into gNB , and each CU could connect with more DUs, multiple structure of CU and DU could sever the demand of diversity of circumstance and telecommunication.
