step S306, after receiving the location update request, the Tiantong roaming gateway (S-CSCF) (i.e. the satellite roaming gateway) registers with the SIP third party in the converged short message center eSMSC;
In step S308, the space-through roaming gateway (i.e. the satellite roaming gateway) returns a location update confirmation message (i.e. the home location update confirmation message).

Specifically, after receiving Invite request message sent by BGCF, MGCF carries out route analysis according to called number, and forwards call to PSTN network, and initiates H.248 message to 1M-MGW to realize media creation MGCF, after receiving media resource response message ACM returned by PSTN network, sends H.248 message to IM-MGW to reserve media resource according to negotiated information, and returns 180Ring response to opposite IMS network. After receiving the response message ANM sent by PSTN network, MGCF sends H.248 message to IM-MGW to start media flow, and sends 200OK message to opposite IMS network to realize session establishment.
In step S206, the target signaling in the second format is sent to the mobile switching center MSC of the satellite network, so as to establish a call between the first user account and the second user account.

step 402, after the telecommunication large network user roams to the heaven-earth network, when the user (i.e. the second user account) receives a short message (i.e. the target short message), the short message is sent to the converged short message center first;
Step 404, the converged short message center eSMSC sends the short message to the Tiantong V2G (i.e. the satellite roaming gateway) based on the form of the SIP short message (i.e. the first format) according to the third party registration information of the satellite roaming gateway;
In step 406, the V2G gateway (i.e. the satellite roaming gateway) performs the mutual transfer from the SIP message (i.e. the target message in the first format) to the MAP message (i.e. the target message in the third format), and sends the message to the space-time MSC (i.e. the MSC of the satellite network) based on the queried routing identifier.

In step S502, after the large network user roams to the Tiantong network, when the user (i.e. the second user account) is called, the voice call is routed to the IMS network to which the user (i.e. the first user account) belongs, and the home IMS network performs call connection.
Step S504, the IMS network I-CSCF inquires the HSS to acquire the S-CSCF to which the user belongs as the Tiantong roaming gateway, and sends the SIP message to the Tiantong roaming gateway.
In step S506, the space-time roaming gateway (i.e. the satellite roaming gateway) implements signaling exchange between SIP (i.e. the first format) and space-time SS7 (i.e. the second format), and the space-time roaming gateway (i.e. the satellite roaming gateway) connects the call to the space-time network, i.e. to the mobile switching center MSC of the satellite network, according to the routing number queried from the space-time network, so as to establish a call between the first user account and the second user account.
As an alternative implementation, after the terrestrial network user roams to the satellite network, the calling procedure and the MO short message procedure may follow the existing procedures.
In order to better adapt to the network withdrawal of a CDMA network and optimize the network structure, the scheme of the application provides a method for mutually roaming a satellite network and a ground 4/5G network, solves the problems that a ground VoLTE/VoNR user roams into a satellite mobile network to update the position, call and send and receive short messages by adding a Tiantong roaming gateway, and only needs a satellite terminal to be compatible with the satellite broadcast equivalent of MCC+MNC in a registered satellite network, and is connected under the condition of not modifying the ground network. On one hand, the VoLTE/VoNR users of the ground network can use the satellite mobile service continuously only by opening the satellite function without changing the card or the number, and on the other hand, the method lays a foundation for the users who develop more subsequent mobile phone direct-connection satellite services.
The application is based on the scheme that the Tiantong roaming gateway enables the ground network user to seamlessly roam into the satellite mobile network to continue using the satellite mobile service, and is less in change to the existing network and saves resources and cost, and the application is oriented to the situation that the user quantity is enlarged by directly connecting the satellite with the subsequent mobile phone.
Through the steps, through newly adding the Tiantong roaming gateway in the satellite mobile network, the purposes that the ground network VoLTE/VoNR user only needs to open the satellite function and continuously uses the satellite mobile service to answer the called call without changing the card or the number are achieved, and the technical problem that the called call cannot be received after the ground network user roams to the satellite network due to the network withdrawal of the CDMA (Code Division Multiple Access ) network is solved.
