Call Detail RecordA call detail record (also known as call data record orCDR) is the computer record produced by a telephoneexchange containing details of a phone call that passedthrough it. It is the automated equivalent of the papertoll tickets that were written and timed by operators forlong-distance calls in a manual telephone exchange.
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 RegisterVisitor Location Register (VLR) is a temporary databaseof the subscribers who have roamed into the particulararea which it serves. Each base station in the network isserved by exactly one VLR, hence a subscriber cannotbe present in more than one VLR at a time.
