Fig. 1 is a flowchart illustrating an embodiment of a method for implementing short message interworking between LTE networks for roaming users according to the present disclosure. The IWF equipment can be added between two operators, and simultaneously supports GMAP and SGd interfaces, so as to realize the short message receiving and sending of LTE roaming users between SGs and SGd operators, and the IWF equipment realizes the following steps through a simulation SMC module, a protocol processing module and a simulation MME module:
in step 110, the emulated SMC (Short Message Center) module receives a Short Message based on a first protocol sent by a roaming network MSC (Mobile Switching Center). Wherein, if the roaming network is the SGs network, the first protocol is the MAP protocol.
In step 120, the emulated SMC module converts the short message based on the first protocol into a short message based on the second protocol through the protocol processing module, and sends the short message based on the second protocol to the emulated MME module. And if the roaming network is the SGs network, the second protocol is a Diameter protocol.
In step 130, the emulated MME module issues the short message based on the second protocol to the home network SMC.
In step 140, the simulation MME module sends a successful delivery response message to the simulation SMC module, so that the simulation SMC module sends the successful delivery response message to the roaming network MSC. Wherein, the subsequent roaming network MSC carries out originating side response and release according to the standard flow.
In the embodiment, the IWF equipment is added between two operators to adapt to different interface signaling, and the short messages under two protocols are converted, so that the short message sending and receiving of LTE roaming users between different operators can be realized without changing the existing network architecture and software and hardware functions.

In step 210, the emulated MME module receives a short message based on the second protocol sent by the home network SMC. And if the roaming network is the SGs network, the second protocol is a Diameter protocol.
In step 220, the emulated MME module converts the short message based on the second protocol into a short message based on the first protocol through the protocol processing module, and sends the short message based on the first protocol to the emulated SMC module. Wherein, if the roaming network is the SGs network, the first protocol is the MAP protocol.
In step 230, the emulated SMC module sends the short message based on the first protocol to the roaming network MSC, so that the roaming network MSC issues the short message based on the first protocol through the roaming network MME.
In step 240, the simulation SMC module receives the successful delivery response message sent by the roaming network MSC, and notifies the home network SMC through the simulation MME module. The simulation SMC module receives a successful issuing response message based on a first protocol sent by a roaming network MSC, converts the successful issuing response message based on the first protocol into a successful issuing response message based on a second protocol through a protocol processing module, and sends the successful issuing response message of the second protocol to a simulation MME module; and the simulation MME module sends a response message of successful issuing of the second protocol to the home network SMC.

In step 310, the roaming terminal initiates a short message, which is sent from the roaming MSC to the home SMC via the SGs interface according to the standard procedure.
In step 320, after receiving the short message based on the MAP protocol, the emulated SMC module converts the short message based on the MAP protocol into a short message based on the Diameter protocol, and sends the short message to the emulated MME module.
In step 330, the simulation MME module issues the short message based on the Diameter protocol to the home SMC, so as to execute the SGd short message related interaction policy at the home.
In step 340, the simulation MME module sends a successful delivery response message to the simulation SMC module.
In step 350, the simulation SMC module sends a successful delivery response message to the roaming MSC so as to execute the interaction policy related to SGs short message origination and release at the roaming site.
In the embodiment, when the roaming user is used as a calling party, IWF equipment is added between LTE core networks to adapt to different interface signaling, and short message sending and receiving of the LTE roaming user between an SGs interface operator and an SGd operator can be realized under the conditions that the existing network architecture and software and hardware functions are not changed and the user is not aware.

The Home SMC sends the route query message to the Home HSS (Home Subscriber Server), step 410. I.e. to query under which device the location of the called terminal is.
The home HSS returns the routing information to the home SMC at step 420.
In step 430, the home SMC sends the Diameter protocol based short message to the emulated MME module through the SGd interface.
In step 440, the emulated MME module converts the short message based on the Diameter protocol into a short message based on the MAP protocol and sends the short message based on the MAP protocol to the emulated SMC module.
In step 450, the emulated SMC module sends a short message based on the MAP protocol to the roaming-place MSC.
In step 460, the MSC at the roaming site sends the MAP protocol-based short message to the MME at the roaming site through the SGs interface for issuing.
In step 470, after the MME at the roaming site successfully issues the message, the MSC at the roaming site replies a response message of successful issuing based on the MAP protocol to the emulated SMC module.
In step 480, the simulation SMC module converts the MAP protocol-based successful delivery response message into a Diameter protocol-based successful delivery response message, and sends the Diameter protocol-based successful delivery response message to the simulation MME module.
In step 490, the emulated MME module notifies the home SMC of a Diameter protocol-based successful response message issued through the SGd interface.
In the embodiment, when the roaming user is called, the IWF equipment is added between the LTE core networks to adapt to different interface signaling, so that short message sending and receiving of the LTE roaming user between the SGs interface operator and the SGd operator can be realized without changing the existing network architecture and software and hardware functions and without perception of the user.

the simulation SMC module is also used for receiving a successful issuing response message based on a first protocol sent by the roaming network mobile switching center MSC, converting the successful issuing response message based on the first protocol into a successful issuing response message based on a second protocol through a protocol processing module, and sending the successful issuing response message of the second protocol to the simulation MME module;
the simulation MME module is also used for sending the response message of successful issuing of the second protocol to the home network SMC.
14. The system of any one of claims 12 or 13,
the first protocol is a MAP protocol, and the second protocol is a Diameter protocol.
15. A system for realizing short message intercommunication of roaming users between LTE networks comprises:
a memory; and
a processor coupled to the memory, the processor configured to perform the method of any of claims 1-7 based on instructions stored in the memory.
16. A computer readable storage medium having stored thereon computer program instructions which, when executed by a processor, implement the steps of the method of any one of claims 1 to 7.
