LTE (Long-Term Evolution) is a standard for wireless broadband communication for mobile devices and data terminals. One of the important parameters in LTE is the ECGI (E-UTRAN Cell Global Identifier), which is used to uniquely identify a cell in the LTE network.

  1. PLMN ID (Public Land Mobile Network Identifier): This is a globally unique identifier for a public land mobile network. It is represented by a MCC (Mobile Country Code) and an MNC (Mobile Network Code).
    • MCC (Mobile Country Code): A three-digit code that identifies the country where the mobile network is registered.
    • MNC (Mobile Network Code): A two or three-digit code that identifies the mobile network within a country.
  2. ECI (E-UTRAN Cell Identifier): This is a unique identifier for a cell within an LTE network. The ECI is often derived from the Cell ID, which is a local identifier for the cell, and the eNodeB ID, which is the identifier for the base station (eNodeB) that manages the cell.

To calculate the ECGI:

  1. Determine the PLMN ID: Combine the MCC and MNC to form the PLMN ID.
    • Example: For MCC=001 (USA) and MNC=01, the PLMN ID would be 00101.
  2. Determine the ECI: The ECI can be a concatenation of the eNodeB ID and the Cell ID.
    • Example: If an eNodeB has an ID of 1234 and a Cell ID of 56, then the ECI might be 123456.
  3. Combine the PLMN ID and ECI: Once you have both the PLMN ID and the ECI, you can combine them to form the ECGI.
    • Example: Using the previous examples, the ECGI might be 0010100123456.
