Telephone number use analysis for grouping of consecutive telephone numbers based on assignment status

摘要

A system may include a network device including a memory. The memory may store a first database including a plurality of records, wherein each record in the first database stores a telephone number (TN) and a status of the corresponding TN. the first database may stores information to indicate whether one of the records in the first database was updated. The memory may store a second database having a plurality of records. Each record in the second database may indicate a range of consecutive TNs from the first database having a same status. The system may include processors to run a first thread to update the one of the records in the first database. The processors may run a second thread to generate the second database from the first database in response to the stored information indicating that the one of the records in the first database was updated.
