Scope

The data stored in location registers are automatically updated in normal operation; the main information stored in a
location register defines the location of each mobile station and the subscriber data required to handle traffic for each
mobile subscriber. The loss or corruption of these data will seriously degrade the service offered to mobile subscribers;
it is therefore necessary to define procedures to limit the effects of failure of a location register, and to restore the
location register data automatically. The present document defines the necessary procedures.
