Referring to fig. 1, fig. 1 is a view of a short message sending scene provided in an embodiment of the present application, where the short message sending scene includes a terminal device 100, a terminal device 200, a communication satellite 300 (illustrated in fig. 1 by using a beidou satellite as an example), a satellite ground station 400, a satellite short message application platform 500, a cellular gateway 600, a short message center 700, and a base station 800. In this embodiment, the terminal device 100 is in a cellular network, the terminal device 200 is in a beidou satellite communication network, and the terminal device 100 sends the short message 1 to the terminal device 200 as an example for illustration; the specific process of the terminal device 100 sending the short message 1 to the terminal device 200 is as follows:
the terminal device 100 in the cellular network accesses the mobile core network by performing signal interaction with the base station 800, the short message 1 sent by the terminal device 100 is sent to the short message center 700 through the mobile core network, and then the short message center 700 sends the short message 1 to the cellular gateway 600 through the mobile core network, the cellular gateway 600 sends the short message 1 to the satellite short message application platform 500, and the short message 1 enters the satellite communication network; then, the satellite short message application platform 500 sends the short message 1 to the satellite ground station 400, and the satellite ground station 400 sends a signal containing the data of the short message 1 to the communication satellite 300 through an uplink; after receiving the signal containing the short message 1 data from the satellite ground station 400, the receiver of the communication satellite 300 amplifies the signal and transmits the amplified signal to the terminal device 200 through the downlink, so that the communication between the terminal device 100 in the cellular network and the terminal device 200 in the beidou satellite communication network is realized.
Similarly, when the terminal device 200 in the satellite communication network sends the short message 2 to the terminal device 100 in the cellular network, the terminal device 200 sends a signal containing the short message 2 information to the communication satellite 300 through an uplink, after the receiver of the communication satellite 300 amplifies the signal, the amplified signal is sent to the satellite ground station 400 through the transmitter, and the satellite ground station sends the short message 2 to the satellite short message application platform 500; the satellite short message application platform 500 sends the short message 2 to a short message center 700 in a mobile core network through a cellular gateway 600, and then the short message center 700 sends the short message 2 to a base station 800 corresponding to the terminal device 100 through the mobile core network; finally, the base station 800 sends the short message 2 to the terminal device 100, so that the short message 2 is transmitted from the satellite communication network to the cellular network, and the terminal device 200 in the satellite communication network and the terminal device 100 in the cellular network are communicated.
Please refer to fig. 2, fig. 2 is a flow chart of a short message sending method according to an embodiment of the present disclosure; as shown in fig. 2, when a first terminal in a cellular network sends a short message to a second terminal in a satellite communication network, the short message needs to be sent from the cellular network to the satellite communication network, so that communication between two terminal devices in different communication networks is implemented, and a specific flow is described with reference to the accompanying drawings:
step S201: and the first terminal and the second terminal respectively update the network positions.
Specifically, before sending the short message, the first terminal and the second terminal need to update their network locations, so that the mobile core network can track and record the location information of the terminal device; therefore, the mobile core network can send the short message to the target terminal equipment.
For example, the embodiment of the present application is exemplified by the case where the first terminal in the cellular network performs location update. Referring to fig. 3, fig. 3 is a scene diagram of location update performed by a terminal device according to an embodiment of the present application; as shown in fig. 3, the mobile service area in which the first terminal is located is divided into several fixed Location Areas (LA)/registration areas (only two are listed in fig. 3), each LA/registration area includes one or more base stations (only four are listed in fig. 3), and the base stations communicate with the terminal device through wireless links; generally, a location management system is composed of a Home Location Register (HLR) and several Visitor Location Registers (VLRs); the HLR and VLR are location management servers, and the location management servers further include other network devices capable of storing location information or data of the terminal device, such as an HSS, which is not limited in the embodiments of the present application. A VLR manages several LAs, each of which consists of a certain number of cells (base stations), and can be hierarchically managed by a number of HLRs when the number of subscribers in a certain area exceeds the number born by one HLR. As shown in fig. 3, the process of the first terminal performing location update is as follows:
in order to determine the precise cell location of the first terminal, the first terminal needs to report its current location to the mobile core network from time to time, which is a location update procedure. The base station broadcasts the address of the corresponding LA/registration area to the first terminal periodically, when the first terminal in standby state enters LA/registration area 2 from LA/registration area 1, the information of LA/registration area 2 received is different from its stored location information (the first terminal stores the location information of LA/registration area 1 previously), the first terminal sends a location updating request/registration information to the base station through the uplink control channel, and then the base station forwards the location updating request/registration information to the mobile core network; the location update request/registration information includes the LA2 number of the new access point of the first terminal and the corresponding base station number, so that the mobile core network can authenticate the first terminal and update data such as the archive of the network location of the first terminal in the location management server. For example, the location update of the first terminal may be a static location update or a dynamic location update (e.g., a distance-based location update, a time-based location update, a motion-based location update, and other dynamic location updates).
Similarly, after the second terminal is accessed to the satellite communication network, the second terminal communicates with the satellite ground station through the communication satellite, then the satellite ground station is accessed to the satellite communication network, the position information is generated through the satellite short message server, the position information of the second terminal is sent to the position management server in the mobile core network through the cellular gateway, and the database of the position management server stores the position information of the second terminal, so that the position update of the second terminal in the mobile core network is realized.
The first terminal and the second terminal respectively update the network positions, which is beneficial for the mobile core network to find out the network positions, thereby sending the short message to the target terminal.
Step S202: the first terminal sends the short message to the short message center.
Specifically, the first terminal sends a signal containing the short message data to a base station through an uplink, and then the base station sends the short message to a corresponding short message center through a mobile core network; the short message includes identification information such as a mobile phone number of the second terminal.
Step S203: and the short message center sends a second position query request to the position management server.
Specifically, the second location query request is used for the short message center to query the location management server whether the current network location of the second terminal is a cellular network or a satellite communication network; and address information of the LA/registration area where the second terminal is located in case that the second terminal is a cellular network; and the second position inquiry request comprises unique identification information such as the mobile phone number of the second terminal and the like which can indicate the identity of the second terminal.
Step S204: and the position management server sends the second position information to the short message center.
Specifically, the second location information is used to indicate a network location where the second terminal is currently located.
Step S205: the short message center sends first indication information to the first terminal.
Specifically, the short message center sends first indication information to a base station of a LA/registration area corresponding to the first terminal through a mobile core network under the condition that the second location information is used for knowing that the current network location of the second terminal is a satellite communication network, and the base station sends the first indication information to the first terminal; the first indication information is used for indicating that the second terminal is currently located in the satellite communication network, and the first indication information comprises operation mode indication information used for sending satellite messages. Illustratively, the first indication information is a recommendation short message, and the content of the recommendation short message may include: the second terminal is currently in the satellite communication network, and may send the satellite message to the second terminal, the tariff for sending the satellite message, and the specific operation mode for sending the satellite message (for example, when the mobile phone number of the second terminal is input, a specific prefix is added, or a specific character is added at the beginning or the end of the short message, and the like) and other information.
Step S206: and the first terminal sends the short message to the short message center based on the first indication information.
For example, after receiving the first indication information, the first terminal may send the short message to the short message center again through the base station based on the operation mode indication information (for example, when a mobile phone number of the second terminal is input, a specific prefix is added or a specific character is added at the beginning or the end of the short message, and the like).
Step S207: and the short message center sends a third position query request to the position management server.
Specifically, the purpose of the short message center querying the network location of the second terminal again is to query whether the second terminal has a situation that the network location of the second terminal changes in a time period from the time when the second terminal queries the network location of the second terminal last time in the short message center to the time when the first terminal receives the short message sent thereto based on the first indication information (for example, switching from the satellite communication network to the cellular network), so that the short message center can take corresponding short message sending measures (for example, when the network location of the second terminal is switched from the satellite communication network to the cellular network, the short message center can directly send the short message to the second terminal through the mobile core network without forwarding through the satellite ground station and the satellite). The third position query request is used for the short message center to query the position management server whether the current network position of the second terminal is a cellular network or a satellite communication network; and address information of the LA/registration area where the second terminal is located in case that the second terminal is a cellular network; and the third position inquiry request comprises identification information which can indicate the identity of the second terminal, such as the mobile phone number of the second terminal.
Step S208: and the position management server sends the third position information to the short message center.
Specifically, the third location information includes a network location where the second terminal is currently located.
Step S209: and under the condition that the second terminal is in the satellite communication network, the short message center sends the short message to a satellite short message server.
Specifically, if the third location information indicates that the network location where the second terminal is currently located is a satellite communication network, the short message center sends the short message to a corresponding satellite short message server through a cellular gateway, so that the short message is transmitted from the cellular network to the satellite communication network.
Step S210: and under the condition of receiving a short message downloading request sent by the second terminal, the satellite short message server sends a first deleting request to the short message center and sends the short message to the second terminal.
Specifically, if a second terminal in a satellite communication network sends a short message downloading request to a satellite short message server through a communication satellite, the satellite short message server sends the short message to a corresponding satellite ground station based on identification information of the second terminal, and then the satellite ground station sends a signal containing the short message information to the communication satellite through an uplink; the communication satellite amplifies the signal and transmits the amplified signal to the second terminal via a downlink, thereby facilitating communication between the first terminal in the cellular network and the second terminal in the satellite communication network. Meanwhile, the satellite short message server sends a first deletion request to the short message center through the gateway equipment; the first deleting request is used for indicating the short message center to delete the short message which is sent to the second terminal by the first terminal and cached by the short message center, so that the storage resource of the short message center is saved.
In a possible implementation manner, if the second terminal in the satellite communication network does not send the short message download request to the satellite short message server, and when the mobile core network detects that the second terminal has switched to the cellular network (for example, the second terminal enters a LA/registration area covered by the cellular network, and updates the network location of the second terminal to the corresponding location management server), the short message center directly sends the short message to the second terminal based on the LA/registration area of the cellular network where the second terminal is located and sends a second deletion request to the satellite short message server, so that the satellite short message server deletes the received short message sent by the first terminal to the second terminal, and does not send the short message to the satellite ground station and the communication satellite. In such a way, the short message stored in the short message center is associated with the short message stored in the satellite short message server, so that the short message is transmitted under the cellular network to the maximum extent, and the load of the satellite communication network is reduced.
Step S211: and under the condition that the satellite short message server receives a short message downloading request sent by the second terminal, the short message center receives the first deleting request and deletes the short message cached by the first deleting request and sent to the second terminal by the first terminal.
In the embodiment of the application, a first terminal in a cellular network sends a short message to a second terminal in a satellite communication network, and a short message center acquires the position information of the second terminal through a position management server; when the network position of the second terminal is the satellite communication network, the short message center sends the short message sent by the first terminal to the satellite short message server through the cellular gateway, so that the short message is transmitted between the cellular network and the satellite communication network; the satellite short message server sends the short message to the corresponding ground satellite station, and the short message is forwarded to the second terminal by the communication satellite, so that the communication between terminals in different communication networks is realized. In the mode, the network position updating function of the cellular network is expanded, the cellular network and the satellite communication network are seamlessly fused, and the advantages of large capacity of the cellular network and wide coverage range of the satellite communication network are respectively exerted, so that users in the cellular network and the satellite communication network can obtain uniform short message service, and accurate and efficient communication service is obtained.

step S401: and the first terminal and the second terminal respectively update the network positions.
Step S401 please refer to step S201 after the step in the embodiment of fig. 2, which is not described again in this embodiment.
Step S402: the first terminal transmits a call request to a voice call server.
Specifically, the destination terminal of the voice call request is a second terminal, and the voice call request includes identification information that can determine the identity of the second terminal, such as a mobile phone number of the second terminal; a first terminal sends a signal including a voice call request to a base station through an uplink, and then the base station sends the signal to a voice call server in a mobile core network; for example, the voice call server may be a network device for voice call, such as a Mobile Switching Center (MSC), and the embodiment of the present invention is not limited thereto.
Step S403: the voice call server transmits a fourth location query request to the location management server.
Step S404: the location management server transmits the fourth location information to the voice call server.
Please refer to steps S203 to S204 or S207 to S208 in the embodiment of fig. 2 from steps S403 to S404, which are not described again in this embodiment.
Step S405: and the voice call server sends the third indication information to the first terminal.
Specifically, the voice call server sends the third indication information to the base station of the LA/registration area corresponding to the first terminal through the mobile core network under the condition that the network location where the second terminal is currently located is the satellite communication network based on the fourth location information, and the base station sends the third indication information to the first terminal; the third indication information is used for indicating that the second terminal is currently located in the satellite communication network and prompting that the first terminal cannot call the second terminal currently. Illustratively, the third indication information is a recommendation short message, and the content of the recommendation short message may include: the second terminal is currently in the satellite communication network, cannot call the second terminal, and can send satellite short messages to the second terminal and information such as specific operation modes of sending satellite messages; the third indication information can also be voice calling of the voice calling server to the first terminal, wherein the voice calling comprises voice information for prompting that the second terminal is currently in the satellite communication network and cannot call the second terminal; for the form of the third indication information, the embodiment of the present application is only for illustration and is not limited.

Please refer to steps S205 to S210 in the embodiment of fig. 2 from step S407 to step S412, which are not described again in this embodiment.
Step S413: and under the condition of receiving a short message downloading request sent by the second terminal, the short message center receives the first deleting request and deletes the short message cached by the first deleting request and sent to the second terminal by the first terminal.
According to the embodiment of the application, when a first terminal in a cellular network calls a second terminal in a satellite communication network, a mobile core network cannot provide voice call service for the first terminal and the second terminal because the two terminals are in different communication networks. Under the condition that the first terminal selects the short message service, the short message center sends the short message sent by the first terminal to the satellite short message server through the cellular gateway, so that the short message is transmitted between the cellular network and the satellite communication network; the satellite short message server sends the short message to the corresponding ground satellite station, and the short message is forwarded to the second terminal by the communication satellite, so that the communication between terminals in different communication networks is realized.
