Here, we will discuss the Location identifiers in LTE mobile network, including the mobile operator identifier, the Tracking Area identifier, and the Cell identifier.
- In LTE mobile network, every eNB consists of several cells, and every group of cells, are grouped into a Tracking Area (TA).
- Therefore, we can say that, the the mobile network consists of several TAs.
Mobile Operator Identifier
- The PLMN ID identifies every mobile network. PLMN refers to 'Public Land Mobile Network'.
- The PLMN ID consists of two parts, the MCC and the MNC.
- MCC refers to 'Mobile Country Code', and it is a unique ID for every country. While MNC refers to 'Mobile Network Code', which is a unique ID for every network inside the country.
Tracking Area Identifier
- We use Tracking Area Code (TAC), in order to locally identify every TA.
- In order to identify the TA globally , we use the TA Identity (TAI).
- The (TAI) consists of the Mobile Country Code (MCC), Mobile Network Code (MNC), and the (TAC).
- The eNB ID identifies Every eNB.
- And the ECI which refers to 'E-UTRAN Cell Identifier', locally identifies every cell inside the network.
- While the ECGI, which refers to 'E-UTRAN Cell Global Identifier', globally identifies every cell.
- The EGCI consists of the MCC, the MNC, and the ECI.
In summary, every group of LTE cells are grouped into a TA.
- And the ECI identifies every cell locally. While the ECGI identifies every cell globally.
- And TAC locally identifies every TA , while TAI globally identified every TA.
