What is the formula for Cell ID (ECI) in LTE networks?


#1

When using GMON in a LTE (4G) Network, i see a cell identification (ECI) with a very large number.

Can anyone tell me how do I calculate this ID?

Hello @rafaeldamasio

The formula is: ECI = 256 * eNBId + Cellid

For Huawei, you can use ECI: 256 * [ENodeBFunction].[eNBId] + [EUtranCellFDD].[Cellid]
And for Ericsson ECI = 256 * [eNodeB].[ENODEBID] + [Cell].[Cellid]

@Carlos_Alberto can you explain further on why number 256, is it the data type UINT8 thats used to describe the same ?
