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.
