A scheme is provided for realizing Mobile Number Portability (MNP) by utilizing a signaling flow of prior mobile network standards such that no modification to the main apparatuses, such as VMSC, GMSC, and HLR, and the like, of the prior networks is required; only a NPDB+ apparatus is required and added, that is, a combination of NPDB and NPHLR. A user of Number portability from an original or home network to a second or other network will be a user of Number Portability out (NP out) among the users of the second network. The number section of the user belongs in the network, and it is able to assign a virtual roaming number to identify the situation of Number Portability (NP) of the user. A user of Number Portability from the second network to the home network is a user of Number Portability in (NP in) among the users of the home network. The NPDB+ apparatus is newly built to store the data of MNP mobile users who enter the home network and to accomplish the associated functions without any modification to the structure of the network. The distribution technology is used for storing the data of the NPDB+. The database is of high reliability such that the circuitous voice circuits do not existed, and the metering between the networks is easy. The newly added apparatus NPDB+ is superimposed on the prior networks, when there are less users during an early period, and only small amount of construction is required. The expansion of the capacity of the networks can be completed by adding portions of an apparatus based on the development condition of MNP services. The expansiveness of the networks is excellent, particularly, it is suitable for the mobile operating agents who have very large scale prior networks.
