As shown in Figure 1, a communication method in the embodiment of the present application can be applied to a satellite fusion gateway, such as a Beidou fusion gateway, wherein the method includes the following steps:

Step 101, after receiving the first transmission information sent by the first network, according to the interface protocol with the first network, acquire the analysis information of the first transmission information.

Wherein, when the first network is a satellite network, according to the interface protocol with the satellite ground station, the first transmission information is analyzed to obtain the analysis information; when the first network is a mobile communication network, according to the interface protocol with the industry gateway, The first transmission information is analyzed to obtain the analysis information. Wherein, the parsing information may include user plane information and signaling plane information of the first transmission information;

Step 102, perform an information processing operation according to the parsing information; wherein, the information processing operation is used to obtain data to be sent and/or perform service management;

In this step, performing the information processing operation may include: processing the first transmission information in terms of information content of business information, business management, business operation and the like.

Step 103, convert the obtained data to be sent into second transmission information according to the interface protocol with the second network.

In this step, the first network is one of a satellite network and a mobile communication network, and the second network is the other of a satellite network and a mobile communication network.

Wherein, when the first network is a satellite network, according to the interface protocol with the satellite ground station, the obtained data to be sent is encapsulated into second transmission information receivable by the mobile communication network; when the first network is a mobile communication network and encapsulating the obtained data to be sent into second transmission information receivable by the satellite network according to the interface protocol with the industry gateway.

Exemplarily, the satellite network includes the Beidou network.

Step 104, sending the second transmission information to the second network.

Wherein, when the second network is a satellite network, the second transmission information socket interface is sent to the satellite ground station to prepare for sending to the satellite; when the second network is a mobile communication network, the sending and receiving service of the mobile side is invoked, by The queue to be sent sends the second transmission information.

The above embodiments solve the communication protocol adaptation problem, connect the satellite network and the mobile communication network, and realize point-to-point and point-to-platform short message applications. That is, it is possible to realize the intercommunication of short messages between satellite-specific terminals and mobile phone users; the intercommunication of short messages between satellite-specific terminal users and other satellite users, and it is also possible for satellite terminals to push short messages of user/terminal location status to the Internet of Things value-added service platform used by the industry. For example, for the Beidou satellite, the dedicated Beidou terminal on the aircraft reports the current location to the airline every ten minutes; as another example, through the subscription authorization of the government and enterprise customers, the Internet of Things platform of the government and enterprise customers can Receive short message information sent by this Beidou IoT terminal in real time. Therefore, the convergence of the communication network is improved.

It should be noted that the sending terminal of the first transmission information may include: a satellite dedicated terminal and a dual-mode terminal (a terminal supporting a satellite network and a mobile communication network).

The implementation of the dual-mode terminal provided in this application may include: the mobile number of the user of the terrestrial mobile operator remains unchanged, the user’s SIM card does not need to be replaced, and the terminal manufacturer transforms the ordinary terminal and adds a radio frequency module for communication with the satellite, so that Dual-mode terminal users can log in both in the mobile communication network and in the satellite short message network, similar to mobile users roaming in satellite areas, but cannot be online in both networks at the same time.

In the following, information processing operations are introduced for different sending terminals respectively.

1. Satellite dedicated terminal

In an embodiment, performing an information processing operation according to the parsing information includes:

It should be pointed out that the number mapping relationship between the sending terminal and the first network side and the second network side includes: there is a one-to-one correspondence between the satellite number and the mobile number. In some embodiments, the satellite-earth fusion communication platform obtains the mapping relationship information between the satellite number and the mobile number during the service provisioning process.

Exemplarily, the number mapping conversion may include: the user's satellite number ID is an 8-digit decimal number, and the ID on the mobile operator side may be mapped one by one to an N-digit decimal number (N>8, generally 16). A legally transferable number within a communication network.

Wherein, one example is: a fixed 8-digit code number prefix of a mobile operator + an 8-digit satellite number ID. In this way, the calling number of each piece of information from the satellite network is mapped to a recognizable number on the mobile communication network side (for example, mapped to an industry gateway code, etc.), and then enters the mobile communication network, and is used by the gateway on the mobile operator side. and received by the SMS center.

It should be pointed out that for the Beidou network, the current industry dual-mode terminals produced by terminal manufacturers: built-in Beidou satellite + mobile two independent SIM cards and numbers. However, the current communication method is: the user uses the Beidou number to receive the short message sent by the calling user on the Beidou side, and uses the mobile number to receive the short message sent by the calling user on the mobile side. It is inconvenient for other users to remember two numbers when sending text messages to dual-mode terminal users; dual-mode terminals must be online at the same time, maintain high power, and have high requirements for terminal battery energy storage; and two completely independent systems are built in, and the cost is relatively high high. However, this application does not require the transformation of the Beidou dedicated terminal, and the number mapping conversion is carried out through the satellite fusion gateway (such as the Beidou fusion gateway), that is, the intercommunication between the Beidou dedicated terminal and the ground mobile communication network can be realized, and the user can solve the amphibious problem of the two networks.

In an embodiment, after converting the calling party number corresponding to the first network in the analysis information into a user number available on the second network side, the method further includes:

In this embodiment, when the customer applies for service activation, he notifies the fusion gateway of the correspondence between the user's mobile operator number and the satellite number. Recording SMS bills can be used as the most reliable basis for the intercommunication and reconciliation of SMS between satellites and telecom operators.

Further, in an embodiment, performing an information processing operation according to the parsing information also includes at least one of the following:

Item 1: Perform service compliance check on the first transmission information based on the analysis information.

In this embodiment, the compliance check includes: checking whether service requirements such as the calling number and the called number comply with the rules. In some embodiments, it may include: whether the calling number has opened the service authority for intercommunicating short messages between satellite and terrestrial mobile communications.

Item 2: Based on the parsing information, perform sensitive word processing on the first transmission information.

In this embodiment, the processing of sensitive words mainly includes: checking whether the content of the message contains any sensitive words that do not meet the regulations, and refusing to forward the message with the sensitive words.

Item 3: Based on the parsing information and the maximum packet length threshold, perform segmentation processing on the first transmission information, and associate the segmented packets.

In this embodiment, since the length of the short message on the satellite network side may exceed the maximum length (such as the number of bytes L) of the short message of the mobile communication network, the satellite fusion gateway is responsible for segmenting the long message according to the number of bytes L. And correlating the segmented messages, so that the mobile terminal can assemble a complete text object according to the original sequence according to the association relationship between the segmented messages after receiving the short message.

Item 4: storing the first transmission information in a mailbox;

Exemplarily, when the dual-mode terminal user is connected to the satellite network, the short messages sent to the dual-mode terminal are temporarily stored in the dedicated mailbox of the dual-mode terminal, waiting for the user to pull and read. Wherein, under the satellite network, when the user of the dual-mode terminal mobile phone initiates to query the messages in the mailbox, the query request will be encapsulated into a short message message as an application layer signaling.

Item 5: Perform blacklist and whitelist processing on the first transmission information based on the analysis information.

Among them, the black list is the number of denial of communication services set for specific users or user groups; the white list is the number of permitted communication services set for specific users or user groups.

In this embodiment, the processing of the black and white lists includes: identifying whether the calling number and the called number are blacklisted users, and if the calling number or the called number is a blacklisted user, then discarding the message and rejecting the service; identifying the calling number and the called number Whether the called number is a whitelist user, and the whitelist user can still send messages even in the case of arrears.

In one embodiment, when the called user terminal is a dual-mode terminal, storing the first transmission information in the mailbox includes:

After receiving the first transmission information sent by the first network, if it is determined that the calling user is a satellite network user, the called user is a ground mobile communication network user, and the called user is connected to the satellite network, then the The first transmission information is stored in the mailbox of the called user, so that the called user obtains the first transmission information from the mailbox; wherein, the dual-mode terminal supports the first network and the second network terminal.

In this embodiment, under the satellite network, a dual-mode terminal user needs to query messages in his own information mailbox and encapsulate them into short message messages.

With regard to the above-mentioned embodiments, the following will give an exemplary introduction to the process of sending and receiving short message information between a satellite dedicated terminal and a public terminal in conjunction with FIGS. 2 to 4 .

Among them, the satellite fusion gateway and the satellite central station send and receive messages to each other. The interface between the fusion gateway and the satellite central station has the ability to negotiate the message sending and receiving rate. When one party needs to change the message sending and receiving rate, it can apply to the other party through the interface protocol; the other party decides whether to accept the request according to its current resource task situation. Once accepted, the message will be sent at the rate required by the other party. The satellite network side communicates with the satellite fusion platform through the satellite central station, and the mobile communication network side communicates with the satellite fusion platform through the industry gateway and SMS center.

In some embodiments, the satellite fusion gateway is mainly divided into five modules according to functions, including:

2. Dual-mode terminal

Exemplarily, the authentication network element of the mobile communication network includes: an authentication server BSF.

In this embodiment, under the mobile communication network, the dual-mode terminal realizes user authentication through the authentication and authentication network element of the mobile communication network, such as the authentication server BSF, and the SIM card calculates the current authentication key and saves it in the security area ; The fusion gateway obtains the user's current communication key from the mobile core network, and saves it. Further, use the saved authentication key to decrypt the application layer message encrypted by the sending terminal to obtain the encapsulated authentication code; then use the key saved by the platform to process the decrypted user short message, independently Deduce the authentication code. If the platform independently deduces that the authentication code is the same as the authentication code that encapsulates the first transmission information, then the user authentication is passed; if the two authentication codes are inconsistent, it is considered that the identity of the calling user is illegal, and the service of forwarding the short message is rejected.

According to the analysis information, the network registration location information of the calling user is synchronized to the home subscriber server HSS or the home location register HLR in the mobile communication network.

In this embodiment, the dual-mode terminal user logs in at the side of the satellite network or the mobile communication network, and needs to synchronize to the HSS (Home Subscriber Server, home subscriber server) or HLR (Home Location Register, home location register) in the mobile communication network Location information of dual-mode end users.

For example, if the last logged-in location of the recorded user is "Beidou Network", the location management does not do anything; if the platform records that the last logged-in location of the user is "mobile communication network", set the user's current location to It is "BeiDou", and the flag that needs to synchronize the position with the mobile communication network is set to 1.

In some embodiments, the location information synchronization on the mobile operator side further includes: the satellite fusion gateway records the location of the user, and reports to the HSS/HLR where the number belongs through the signaling network that the user has roamed to the satellite network.

In some embodiments, the satellite network side location information synchronization also includes: when the dual-mode terminal user returns to the mobile communication network, the current location authentication module of the mobile communication network of the user authenticates the number user; after the authentication is completed, Mobility management is responsible for reporting to the HSS/HLR where the number belongs that the user has returned to the ground mobile communication network. HSS/HLR will notify the satellite-ground fusion communication platform of the current network of the user through the cancel location command.

In this embodiment, the processing of sensitive words mainly includes: checking whether the content of the message contains sensitive words that do not meet the requirements, and refusing to forward the message with sensitive words.

Step 3-12: send and receive information;

Queue up the sending and sending service of the short message, and forward it to the mobile communication network side.

Example two

Referring to Figure 7, the dual-mode terminal sends text messages to the mobile number through the satellite network, and the called mobile number uses a dual-mode terminal and is connected to the satellite network. The process mainly includes the following steps:

Step 4-1: Information (referring to the above-mentioned first transmission information) is sent and received.

Step 4-2: Protocol adaptation.

Step 4-3: Business rule checking.

Step 4-4: Logic Control.

Call the logic control service to do logic control for the processing of different businesses;

Step 4-5: Decryption authentication.

Decrypt the message on the application plane, and calculate the authentication code based on the previously saved authentication key of the user. If the calculated authentication code is consistent with the authentication code carried in the message, the authentication is passed.

Step 4-6: black and white list processing.

Steps 4-7: Location Management.

Steps 4-8: Mailbox processing.

When it is judged that the called user (dual-mode terminal) is connected to the satellite network, the short message is stored in the mailbox of the satellite fusion gateway, and waits for the called user to obtain.

Steps 4-9: Bill generation.

Steps 4-10: Location Synchronization.

According to the query results of steps 4-7, if the calling user did not log in from the Beidou network last time, the location information of the calling user is synchronously updated to the mobile communication network.

Example three:

Referring to Fig. 8, the process of receiving the short message from the mobile operator side mainly includes the following steps:

Step 5-1: Information sending and receiving.

The short message sent from the mobile communication network side is sent to the Beidou fusion gateway through the socket interface, and queued for protocol adaptation service processing;

Step 5-2: Protocol adaptation.

Through the No. 7 signaling interface protocol, the user-side content and signaling content of the short message are analyzed separately, and the user-side and signaling-side information of the message are respectively obtained.

Step 5-3: Business rule checking.

The business rule checking secondary module checks whether the user has opened the service provided by this platform, and whether the digits of the number are in compliance, and if it is in compliance, the logic control service is invoked;

Step 5-4: Logic control.

Step 5-5: black and white list processing.

Step 5-6: Mailbox processing.

Compliant short messages are stored in the mailbox, waiting for the called user to pull them from the Beidou network side. Wherein, when the information is sent successfully, the information is deleted from the mailbox.

Step 5-7: Bill generation.

Generate a list of user text messages for reconciliation.

Example four

Referring to Figure 9, the dual-mode terminal queries and obtains the short message from the mailbox, which mainly includes the following steps:

Step 6-1: Information sending and receiving.

Under the satellite network, dual-mode terminal users want to query the messages in their own information mailboxes, and the request is encapsulated into a short message message as an application layer signaling. The dual-mode terminal operates on the short message through the key to generate an authentication code; then encrypts the authentication code + short message with an agreed algorithm. The encrypted message is pushed to the satellite-ground fusion communication platform through the Beidou central station for caching.

Step 6-2: Protocol adaptation.

According to the interface protocol, the platform obtains the user plane and signaling plane information of the message respectively. The user plane message is an encrypted application layer message.

Step 6-3: Business rule checking.

Check the rationality of the message on the signaling plane, such as whether the length of the calling and called numbers is reasonable, whether the calling user has applied for the satellite short message service, and whether it is in arrears.

Step 6-4: Logic control.

According to the service type of the short message (whether it is a dedicated terminal service or a dual-mode terminal service), a subsequent processing procedure is selected.

Step 6-5: Decrypt authentication.

Step 6-6: black and white name processing.

Judging whether the calling number is in the blacklist, if it is a blacklist number, the message will be discarded and the service will be rejected; the whitelist user can still send the message in the case of arrears.

Step 6-7: Location Management.

In the location register on the query platform, whether the user logged in from the mobile network or the Beidou network last time, if the user logged in from the mobile communication network last time, set the user location register to log in from the Beidou side, and call the mobile access process The location synchronization service of the user notifies the corresponding HSS of the user that the number has roamed in the Beidou domain, and then invokes the mailbox processing service.

Steps 6-8: Mailbox processing.

After receiving the pushed SMS, the dual-mode terminal generates a receipt for each successfully received SMS. After the receipt arrives at the platform, the mailbox learns that the specific short message has been successfully received by the user through application layer signaling analysis, and then deletes the short message in the mailbox.

Steps 6-9: Bill generation.

Generate a list of user text messages for reconciliation.

It should be noted that, the order of the steps in the above example 1 to example 4 is only an example, and can be adjusted according to actual conditions.

Further, in an example, when the sending terminal of the first transmission information is a dual-mode terminal, sending the second transmission information to the second network includes:

In the above-mentioned embodiment, in the implementation design of sending short messages to mobile users by the dual-network users of the satellite side No. 1, the route of the intercommunication gateway and the short message center (such as the MT short message center) is taken. The short message center will not check the origin of the calling number, but will only check the called roaming place, and send the short message to the local network of the roaming place through the IP or No. 7 signaling network; the realization of mobile users sending short messages to the No. In the design, the No. 7 signaling route is taken through the built-in BDMSC (MSC of the satellite domain end office) of the satellite fusion gateway. The satellite domain end office accesses the No. 7 signaling network of the mobile telecom operator through the BDMSC, and the operator's SMS centers all over the country can push the SMS to the BDMSC through the No. 7 signaling network.

In the above-mentioned embodiments, terminals with mobile and satellite dual-mode communication capabilities (types including professional terminals, smart phones, etc.) only need to be equipped with identity authentication information (such as a mobile SIM card) for a separate mobile communication network; with satellite single-mode communication capabilities The terminal is only equipped with the identity authentication information of the satellite network, and can also communicate with the terminal and platform of the mobile communication network through functions such as number mapping of this platform. Therefore, through the construction of a satellite-ground integrated communication platform, it is possible to achieve satellite users accessing the mobile communication network through a general SMS gateway without any changes on the UE side, and to communicate with mobile users by SMS; Mobile operator users can send and receive text messages through satellite channels without mobile communication network coverage, without changing numbers or SIM cards. By adding the UE with satellite radio frequency, the majority of mobile phone user groups can realize the online global short message service through satellite by activating the satellite short message value-added service, which is of great value to professional markets such as vehicles, ships and seas.

In summary, the above scheme has the following advantages:

Low cost: In the dedicated terminal solution, there is no need to modify the terminal. In the dual-mode terminal solution, only a small modification is made to ordinary mobile phones, and the cost is low.

Good user experience: In the dedicated terminal solution and the dual-mode terminal solution, the intercommunication between satellite short messages and mobile operator short messages can be realized without the need for users to change cards or numbers.
