Call Detail Record

A call detail record (also known as call data record or

CDR) is the computer record produced by a telephone

exchange containing details of a phone call that passed

through it. It is the automated equivalent of the paper

toll tickets that were written and timed by operators for

long-distance calls in a manual telephone exchange.

Database structure of Telecom company

Concept of Roaming

Generally for every

mobile signal cell, there

are two registers or

databases.

Home Location Register.

Visitor Location

Register.

Home Location Register

Home Location Register (HLR) is a central database that

contains details of each mobile phone subscriber that is

authorized to use the core network. The HLRs store details of

every SIM card issued by the mobile phone operator.

. The HLR data is stored for as long as a subscriber remains

with the mobile phone operator. HLR also manages the

mobility of subscribers by means of updating their position in

administrative areas. It sends the subscriber data to a Visitor

Location Register (VLR).

Visitor Location Register

Visitor Location Register (VLR) is a temporary database

of the subscribers who have roamed into the particular

area which it serves. Each base station in the network is

served by exactly one VLR, hence a subscriber cannot

be present in more than one VLR at a time.
