Service management for IN-based local number portability

ns liberalization has swept through the telecommunications industry, the issue of number portability has become increasingly important. Number portability is the key to open competition in local services. Local number portability (LNP) is a circuit switched network capability which allows an end-user to change service provider, location and/or service type without having to change his/her telephone number. There are several LNP solutions, but the industry considers the location routing number model the best way to implement LNP, which depends on intelligent network (IN) technology. In this paper, we propose TMN-based service management architecture for LNP which has an IN-based solution. Under the proposed architecture, we also describe the service management mechanism.
