<p>The invention provides a number conversion method, which includes: a calling user initiates a call in a circuit switched domain; the core network of the circuit switched domain sends a session invitation message to the Service Continuity Application Server (SC AS) to which the calling user belongs; and after receiving the session invitation message, the SC AS compares the calling user number in the session invitation message with the user data of the calling user, and sets the calling user number in the session invitation message based on the comparison result, then forwards the session invitation message to the called user. The invention also provides a Service Continuity Application Server. In the invention, by converting the calling user number, an appropriate calling user number can be sent to the called user based on the demand.</p> |
