Abstract
A method and system for implementing inter-network SMS interworking in NP service are provided in the present invention. The method includes: before initiating a MT-SMS, if a first SMS Center of GSM network (G1-SMSC) judges that the destination user is not a user of local network, then it delivers a SRI message to an interworking SMSC; the interworking SMSC queries the NPDB in CDMA network for the home network of the destination MDN, and if the home network is a second GSM network, the interworking SMSC sends a SRI message carrying the destination MDN to the HLR in the second GSM network (G2-HLR); and G2-HLR sends a SRI response carrying the address information of the MSC where the destination user is located to G1-SMSC, and the G1-SMSC initiates a MT-SMS to the MSC where the destination user is located according to the address information.
