[0025] When the present invention realizes the mobile inter-network number carrying MNP service, such as figure 2 As shown, in one region, there are multiple mobile operators: operator 1, operator 2, and operator n. The network of each operator is based on a number of signaling points connected to the No. 7 (SS7) signaling network 11 by signaling links, among which: signaling point signaling transfer point STP and voice and data switching node, switching The nodes are Mobile Switching Center 12 (MSC), Short Message Center 13 (SMSC), Media Switching Center 14 (MMSC), Gateway Mobile Switching Center 15 (GMSC) and Home Register 16 (HLR).
[0026] First, an independent local number portability database 2 is deployed. The local database includes a number portability processing device 21 (SRF-NPDB) with signaling relay function SRF and a local service management device 22 (LSMS). in:
[0027] The number portability processing device SRF-NPDB, as an independent signaling point equ...
