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.
2. The method according to claim 1 , wherein the querying, by a SMSF entity, an information of a network function capable of providing a MO SMS forwarding service from a NRF entity comprises:
querying, by the SMSF entity, the information of the network function capable of providing the MO SMS forwarding service from the NRF entity according to at least one of a Subscription Permanent Identifier (SUPI), a Generic Public Subscription Identifier (GPSI), or an address of the SC, wherein the information of the network function capable of providing the MO SMS forwarding service comprises an IP address or a Fully Qualified Domain Name (FQDN) address of the SMS-IWMSC.
3. The method according to claim 2 , further comprising:
sending, by the SMSF entity, a callback IP address and an information of a timer for waiting to the SMS-IWMSC during a process of sending the short message to the SMS-IWMSC.
4. The method according to claim 3 , further comprising:
sending, by the SMS-IWMSC, a delivery report, which is sent by the SC, to the SMSF entity according to the callback IP address or a FQDN address of the SMSF entity; and
sending, by the SMSF entity, the delivery report to the user equipment.
5. The method according to claim 4 , wherein:
the SMSF entity and the SMS-IWMSC interact through a service-based interface.
6. The method according to claim 1 , further comprising:
registering, by the SMS-IWMSC, a capability of providing the MO SMS forwarding service in the NRF entity during a network function registration procedure.
7. The method according to claim 1 , further comprising:
sending, by the SMSF entity, the short message to an IP-Short Message-Gateway (IP-SM-GW), in a case where it is determined that the IP-SM-GW and the SMS-IWMSC are capable of providing the MO SMS forwarding service according to the query result; and
sending, by the IP-SM-GW, the short message to the SMS-IWMSC.
8. The method according to claim 7 , further comprising:
sending, by the SMS-IWMSC, a delivery report, which is sent by the SC, to the IP-SM-GW;
sending, by the IP-SM-GW, the delivery report to the SMSF entity; and
sending, by the SMSF entity, the delivery report to the user equipment.
9. The method according to claim 8 , wherein:
the SMSF entity and the IP-SM-GW interact through a service-based interface; and
the SMS-IWMSC and the IP-SM-GW interact through a service-based interface.
10. The method according to claim 7 , further comprising:
registering, by the SMS-IWMSC, a capability of providing the MO SMS forwarding service in the NRF entity during a network function registration procedure; and
registering, by the IP-SM-GW, a capability of providing the MO SMS forwarding service in the NRF entity during a network function registration procedure.
11. A system for realizing a service-based Mobile Originated Short Message Service, comprising:
a Short Message Service Function (SMSF) entity configured to query 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, and send 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;
the NRF entity configured to provide an information of a network function with a capability of the MO SMS forwarding service;
the SMS-IWMSC configured to send the short message to a Service Center (SC) of the short message; and
the SC configured to send the short message to a corresponding receiver of the short message.
12. The system according to claim 11 , wherein:
the SMSF entity is configured to query the information of the network function capable of providing the MO SMS forwarding service from the NRF entity according to at least one of a Subscription Permanent Identifier (SUPI), a Generic Public Subscription Identifier (GPSI), or an address of the SC, wherein the information of the network function capable of providing the MO SMS forwarding service comprises an IP address or a Fully Qualified Domain Name (FQDN) address of the SMS-IWMSC.
13. The system according to claim 12 , wherein:
the SMSF entity is further configured to send a callback IP address and an information of a timer for waiting to the SMS-IWMSC during a process of sending the short message to the SMS-IWMSC.
14. The system according to claim 13 , wherein:
the SMS-IWMSC is further configured to send a delivery report, which is sent by the SC, to the SMSF entity according to the callback IP address or a FQDN address of the SMSF entity; and
the SMSF entity is further configured to send the delivery report to the user equipment.
15. The system according to claim 14 , wherein:
the SMSF entity and the SMS-IWMSC interact through a service-based interface.
16. The system according to claim 11 , wherein:
the SMS-IWMSC is configured to register a capability of providing the MO SMS forwarding service in the NRF entity during a network function registration procedure.
