4G network identity

“

(gentle music) - [Instructor] Let's understand the network identities used within different eNodeBs in LTE. There are two key IDs we are focusing upon. One is the cell global identity. As name signifies, this is the identity which is globally unique for individual cell. We know within a eNodeB, within a base station, there are different cells. So each cell has unique ID globally, that is ECGI in case of 4G. Similarly, we have the PCI, which is physical cell ID. So, physical cell ID is used for initial synchronization. Now, these IDs are being defined by the operator and can be reused after a particular geography. But ECGI is the unique ID that has been allocated to the different cells. Now, how this ECGI is made of different components, let's focus on that. So ECGI, we are saying that a particular site for a particular operator and within a particular country, that is specifically unique. Now, we will be starting with the network ID in that case, which consists of the MCC and MNC. We…
