Young Sic Jeong, Whan-Woo Kim · 2005
This paper describes a method to implement mobile number portability (MNP) in Korea. The MNP system consists of two function blocks, one the call processing system and the other the subscriber management system. The hardware structure and processing method of the system are presented in this paper. The call processing system uses the QoR method and consists of intelligent network exchanges and local number portability database (L-NPDB) system. The subscriber management system consists of the interconnection system of master-NPCDB (NP customer database, M-NPCDB), local-NPCDB, M-NPDB and L-NPDB. The master database is interconnected to the local database through a dedicated line and can process any MNP service in real time. The presented MNP structure in this paper has been implemented in Korea and the result is quite successful.
