1. A method for realizing a service-based Mobile Originated Short Message Service, comprising:
querying, by a Short Message Service Function (SMSF) entity, an information of a network function capable of providing a Mobile Originated Short Message Service (MO SMS) forwarding service from a Network Repository Function (NRF) entity, after receiving a short message transferred from a user equipment;
sending, by the SMSF entity, the short message to an Interworking Mobile Switching Center for Short Message Service (SMS-IWMSC), in a case where it is determined that the SMS-IWMSC is capable of providing the MO SMS forwarding service according to a query result; and
sending, by the SMS-IWMSC, the short message to a Service Center (SC) of the short message, so that the SC sends the short message to a corresponding receiver of the short message.
