Mobile entities

Equipment Identity Register (EIR)

• This functional entity contains one or several databases which

store(s) the IMEIs used in the GSM system.

• The mobile equipment may be classified as “white listed”,

“grey listed” and “black listed” and therefore may be stored

in three separate lists.

• An IMEI (International Mobile Equipment Identifier) may also be

unknown to the EIR.

• An EIR shall as a minimum contain a “white list” (equipment

classified as “white listed”).
