(3) the calling user attributive SMC initiates an 'MT Forward Short Message' request Message of a MAP protocol, and a destination address is a service platform and carries a calling number and Short Message content;

(4) the method comprises the steps that a service platform receives an MT Forward Short Message request Message, after a privacy number service logic is executed, an MO Short Message flow is initiated to a called user, the address of a privacy number attribution SMC is extracted from stored information, an MO Forward Short Message request Message of an MAP protocol is initiated to the privacy number attribution SMC, and a target address is the service platform and carries a called number and Short Message content;

(5) the privacy number attribution SMC returns a response Message of 'MO Forward Short Message';

(6) and the service platform returns an MT Forward Short Message response Message to the home SMC of the calling party.

(eighth) as shown in fig. 7, after the registration process of the privacy number is completed in the service platform, an interactive process of sending a short message to a called subscriber number in a non-IMS network is performed:

(1) the service platform extracts the home short message center address of the privacy number from the storage information of the privacy number;

(2) the platform initiates a 'MO Forward Short Message' request Message of a MAP protocol, and a destination address is a home Short Message center of a privacy number;

(3) the attributive Short Message center of the privacy number receives an MO Forward Short Message request Message of an MAP protocol and returns an MO Forward Short Message response Message;

(4) the attribution Short Message center of the privacy number executes the MT Short Message process of the called subscriber number, initiates a 'Send Routing info Short Message' request Message of a MAP protocol to the HSS to which the called subscriber number belongs, and inquires the Short Message Routing address of the called subscriber number; the called home HSS returns a 'Send Routing info Short Message' response Message of the MAP protocol, and carries the current Short Message Routing address of the called subscriber number, namely the called subscriber number roaming end office;

(5) the home short message center of the privacy number sends the short message to the called number roaming end office, and the called number roaming end office is responsible for sending the short message to the terminal of the called number.

The privacy number described in this embodiment is a mobile phone number of a telecom operator, can perform an account opening operation through a normal telecom operator account opening channel, and has a VoLTE attribute.
