What is EIR (Equipment identity register)?

The Equipment Identity Register (EIR) is a network entity utilized in GSM. EIR saves lists of International Mobile Equipment Identity (IMEI) numbers, which correspond to physical handsets. The EIR element can be utilized to lessen the quantity of GSM handset thefts by giving a system that permits network administrators to keep taken or prohibited handsets from accessing to the network. An Equipment Identity Register (EIR) assists administrators with shielding their
networks and revenues from unauthorized devices being utilized.
