Central Equipment Identity Register (CEIR) Objectives, Working, IMEI Database, Aim



Central Equipment Identity Register (CEIR) is a database of the IMEI numbers of blacklisted handsets.

In India, There are 980 Million wireless subscribers with 12 Telecom Service provider (TSPs) as on Sept 2015.

Each TSP has their own Equipment Identity Register (EIR) to register International Mobile Equipment Identity (IMEI) number of the mobile handset which is used for tracking of devices.

In traditional telecom infrastructure, this EIR is separate for each TSP and updated regularly.

The subscriber loses his or her mobile handset, the telecom service provider blocks the IMEI of that handset in its own network to make the handset useless and cannot be misused by the thief.

If the thief changes the SIM card, the mobile handset is latched to other networks in which the IMEI of that handset is not blocked, thereby giving the thief an authorized access to the network.

Network operators to compile one global blacklist through the IMEI DB. However, there is no agreement on a single CEIR.

These issues were continuously happening in the past and TRAI observed these limitations with the existing model and came up with a new model that includes a central equipment identity register (CEIR) database in the system.

CEIR’s paper reviews traditional EIR model, limitation of EIR and proposed CEIR model based on qualitative analysis of TSPs responses and quantitative analysis of public responses. After enabling CEIR model TSPs can track any mobile device throughout the network.
