C-RAN - BBU Pool

BetterMing · Created Jun 9, 2020 01:31:57

On hardware: The solution is to use multiple BBUs to centrally place shared resources to form a BBU-POOL. As long as the RRU is connected to any BBU in the BBU-POOL, it can use the resources in the BBU-POOL.
In U2000, you want to distinguish whether RRU uses BBU-POOL resources. You can use the function of creating a virtual network element. Distinguish devices logically.

Creating a Virtual NE

Virtual NEs refer to NE mappings that cannot be managed using the U2000 on the entire network. You can easily understand the entire network by adding virtual NEs to the topology view.

Procedure

Choose Topology > Main Topology (traditional style); alternatively, double-click Topo View in Application Center and choose Topology > Main Topology (application style).
Select one of the following methods to create a virtual NE:

NOTE:

When a subnet is selected, choose New > NE. The created NE is displayed in the topology view of the current subnet.
To create the virtual NE in Current Path where the current topology view is located, right-click in a blank area in the topology view and choose New > NE from the shortcut menu.
Click on the toolbar and choose NE.
In the navigation tree of the topology view, right-click a subnet and choose New > NE from the shortcut menu.
Right-click in the topology view and choose New > NE from the shortcut menu.

In the Create NE dialog box, set information about the virtual NE, including Name, Vendor, Physical Location, District, and IP Address.

Click OK.

The Operation Progress dialog box is displayed, showing the progress of creating NEs. After the NEs are created successfully, the created virtual NE is displayed in the current view.

Hi @BetterMing

I already read it. I know the concept but I want to know more in a practical way - if operators are using it and how Huawei - for example how I can see it or configure in U2000 - is implementing it.

Both, in my opinion (HW and SW).
Two spheres:
- Network Function hosted on Hardware
- Connections RRU-BBU

NFs: Hosting Network Function (like BTS, NodeB, eNodeB, gNodeB) on Hardware (like BBU, RRU)
In terms of connection RRU - BBU, how works with "bbu-pool"?

How it is implemented? We have a set of BBUs which belong to a "bbu-pool" and RRUs are connecting to the "bbu-pool" aand not to a specific BBU? How I can see it in U2000 or at device level config (BBU and RRU)?

And about the RRU connectivity configuration? It connects directly to the BBU or to the BBU-pool?

This is classified according to the actual situation. If the RRU physical connection is a BBU in BBU-POOL, it is connected to BBU-POOL. If it is connected to an ordinary BBU, it is a normal connection.

Any hint about the association of BBU with BBU-POOL?

Yes, the BBUs in the BBU-pool are related to each other.
