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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, system and device for implementing inter-network short message service intercommunication in number portability service","description":"A method and system for implementing inter-network SMS interworking in NP service are provided in the present invention.
