(2), after the intelligent platform receives the IDP message, it sends a query message to the number portability database (NPDB, NumberPortability Database) to query the mobile user's number portability (NP, NumberPortability) status, where the query message can be any time query message ATI , it can also be other message to Query NPDB carrying database messages;

(3), the number portability database returns the query result, that is, the number portability information to the intelligent platform, wherein the number portability information includes the routing number of the home network, the user NP status and the user number, and the intelligent platform triggers different intelligent services according to the NP query results ;

(4), the intelligent platform sends a connection (Connect) message to the mobile switching center;

(5), the mobile switching center receives the connection message, if the routing number (RN, Routeing Number) of other networks is carried in the connection message, then the initial address message (IAM, IAM) is sent to the gateway mobile switching center (GMSC, GatewayMobile Switching Center). Initial Address Message) message to trigger the call process, otherwise a call routing message (SRI, Send Routing Information) is initiated on the local network to trigger the call process.

The above-mentioned number portability database NPDB can be built into the smart platform, or can be independent of the smart platform, but both methods have the following defects:

When the intelligent platform processes intelligent services, it also needs to query the corresponding NP information from the NPDB database, which puts considerable pressure on the intelligent platform and makes it difficult to carry out intelligent services; The cost of improving each intelligent platform is relatively high.
