Explanation ⦂

MIR is not a database in a GSM network. HLR, VLR and AIR all are databases in the GSM network.

• Home Location Register (HLR) is a database on the GSM network, which is used for the storage and management of subscriptions. It is considered the most important database of the GSM network, as it stores permanent data about the subscribers.
• Visitor Location Register (VLR) is a database of GSM networks that collects temporary information about customers that is required to serve customers coming from MCS. VLR integrates with MCS.
• Equipment Identity Register (EIR) is also the database of GSM networks. It contains a list of all the devices on the network. Here the International Mobile Equipment Identity IMEI identifies each SMS.
