As shown in fig. 1, the communication method according to the embodiment of the present invention may be applied to a satellite convergence gateway, such as a beidou convergence gateway, where the method specifically includes the following steps:

step 101, after receiving first transmission information sent by a first network, acquiring analysis information of the first transmission information according to an interface protocol with the first network.

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

102, executing information processing operation according to the analysis information; the information processing operation is used for obtaining data to be sent and/or performing service management;

in this step, performing the information processing operation may include: and processing the first transmission information aiming at the aspects of service information content, service management, service operation and the like.

Step 103, converting the obtained data to be transmitted into second transmission information according to an interface protocol with a second network; wherein the first network is one of a satellite network and a mobile communication network, and the second network is the other of the satellite network and the mobile communication network.

When the first network is a satellite network, the obtained data to be sent is encapsulated into second transmission information which can be received by a mobile communication network according to an interface protocol with a satellite ground station; and when the first network is a mobile communication network, packaging the obtained data to be sent into second transmission information which can be received by the satellite network according to an interface protocol with an industry gateway.

Illustratively, the satellite network comprises a Beidou network.

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

when the second network is a satellite network, a second transmission information socket interface is sent to a satellite ground station to prepare for sending to a satellite; and when the second network is a mobile communication network, calling the transceiving service of the mobile side, and sending the second transmission information by putting the transceiving service into a queue to be sent.

The embodiment solves the problem of communication protocol adaptation, and pulls through the networks at the satellite and the mobile communication network side, thereby realizing point-to-point and point-to-platform short message applications. Namely, the short message intercommunication between the satellite special terminal and the mobile phone user can be realized; the satellite special terminal user and other satellite users intercommunicate short messages, and the satellite terminal can also push the short messages of user/terminal position state class to the value-added service platform of the internet of things for industry. For example, for the Beidou satellite, the Beidou special terminal on the airplane reports the current position to the airline company every ten minutes, and the like; for another example, a telecom operator subscribes and authorizes a government-enterprise client, and an internet of things platform of the government-enterprise client can receive short message information sent by the Beidou internet of things terminal in real time.

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

The dual-mode terminal provided by the application means that a user is a user of a ground mobile operator, the mobile number of the user is not changed, the SIM card of the user does not need to be replaced, and a terminal manufacturer improves a common terminal and adds a communication radio frequency module with a satellite, so that the dual-mode terminal user can log in a mobile communication network and also can log in a satellite short message network, similar mobile users roam in a satellite area, but can not be simultaneously online in two networks.

Next, the information processing operation will be described with respect to the difference between the transmission terminals.

Special terminal for primary satellite and satellite

In one embodiment, according to the parsing information, performing information processing operations includes:

It should be noted that the number mapping relationship between the sending terminal and the first network side and the second network side refers to: the satellite numbers and the mobile numbers are in one-to-one correspondence, and specifically, in the service opening process of the satellite-ground converged communication platform, mapping relation information of the satellite numbers and the mobile numbers is obtained.

Illustratively, the number mapping conversion may include: the user's satellite number ID is an 8 digit decimal number, and the mobile operator side ID can be mapped one-to-one to an N digit decimal number (N >8, typically 16) which is a legally deliverable number within the mobile communication network.

One specific example is: the fixed 8 mobile operator's code number prefix +8 satellite number ID. Therefore, the calling number of each piece of information from the satellite network is mapped to a number (such as an industry gateway code) which can be identified by a mobile communication network side, and then enters the mobile communication network to be received by a gateway and a short message center of a mobile operator side.

It should be noted that, for the beidou network, in the industry dual-mode terminal manufactured by the terminal manufacturer at present: the Beidou satellite and mobile two independent SIM cards and numbers are built in. However, the current communication method is: the user receives the short message sent by the Beidou side calling user by the Beidou number and receives the short message sent by the mobile side calling user by the mobile number. It is inconvenient for other users to remember two numbers for sending short messages to the dual-mode terminal user; the dual-mode terminal needs to be on line at the same time, maintains higher power and has high requirement on energy storage of a terminal battery; and two completely independent systems are arranged in the system, so that the cost is higher. But this application need not reform transform big dipper private terminal, fuses the gateway through the satellite (if big dipper) and carries out the number mapping conversion, can realize big dipper private terminal and ground mobile communication network intercommunication promptly, solves the user and perchs the problem in two networks pair.

In an embodiment, after the mapping of the calling party number corresponding to the first network in the resolution information is converted into the subscriber number available to the second network side, the method further includes:

Item 2: sensitive word processing is carried out on the first transmission information based on the analysis information;

in this embodiment, the sensitive word processing mainly includes: and checking whether the message content contains sensitive words which do not accord with the regulation, and refusing to forward the message with the sensitive words.

Item 3: based on the analysis information and the maximum message length threshold value, carrying out segmentation processing on the first transmission information, and associating the segmented messages;

in this embodiment, since the length of the short message at the satellite network side may exceed the maximum length (e.g., byte number L) of the short message in the mobile communication network, the satellite convergence gateway is responsible for performing segmentation processing on the long message according to the byte number L and associating 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;

illustratively, when a dual-mode terminal user is connected to a satellite network, short messages sent to the dual-mode terminal user are temporarily stored in a special mailbox of the dual-mode terminal user and wait for the user to pull for reading. Under the satellite network, a user of the dual-mode terminal mobile phone needs to inquire the information in an information box of the user, and the requirement is used as an application layer signaling to be packaged into a short message.

Item 5: and performing black and white list processing on the first transmission information based on the analysis information.

The blacklist is a communication service rejection number set for a specific user or a user group; the white list is a permitted communication service number set for a specific user or group of users.

In this embodiment, the black and white list processing includes: identifying whether the calling number and the called number are blacklist users, and if the calling number or the called number are blacklist users, discarding the message to reject the service; and identifying whether the calling number and the called number are white list users, wherein the white list users can still send messages under the condition of arrearage.

According to the query results in the steps 1-7, under the condition that the calling party does not log in from the Beidou network last time, the position information of the calling party 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 mainly includes the following steps:

step 2-1: information is received and transmitted;

short messages sent from the mobile communication network side are sent to the Beidou convergence gateway through a socket interface, and are queued for protocol adaptation service processing;

step 2-2: protocol adaptation;

analyzing the user side content and the signaling content of the short message respectively through a No. 7 signaling interface protocol, and acquiring the user plane and signaling plane information of the message respectively;

step 2-3: checking a business rule;

step 2-4: logic control

step 2-5: black and white list processing

Step 2-5: mailbox handling

And storing the compliant short message into a mailbox, and waiting for the called user to pull the message from the Beidou network side. And when the information is successfully sent, deleting the information from the mailbox.

Step 2-6: ticket generation

And generating a short message list of the user for account checking.

Example four

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

step 1-1: information receiving and transmitting

Under the satellite network, a dual-mode terminal user needs to inquire the information in an information box of the user and package the requirement as application layer signaling into a short message. The dual-mode terminal operates the short message through the key to generate an authentication code; then the authentication code and the short message are encrypted by a well-agreed algorithm. And the encrypted message is pushed to a satellite-ground converged communication platform through the Beidou central station for caching.

Step 1-2: protocol adaptation

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

Step 1-3: business rule checking

Checking the rationality of the signaling plane message, such as whether the length of the calling number and the called number is reasonable, whether a calling user applies for the satellite short message service, whether the service is owing, and the like;

step 1-4: logic control

And selecting a subsequent processing flow according to the service type (the special terminal service or the dual-mode terminal service) of the short message.

Step 1-5: decryption authentication

step 1-6: black and white name processing

Judging whether the calling number is in a blacklist, if so, discarding the message rejection service; the white list user can still send the message under the condition of arrearage;

step 1-7: location management

Inquiring a position register on the platform, wherein the user logs in from a mobile network or a Beidou network last time, if the user logs in from the mobile communication network last time, the position register of the user needs to be set to be the Beidou side login, informing the HSS corresponding to the user that the number has roamed in the Beidou domain, and then calling mailbox processing service.

Step 1-8: mailbox handling

After receiving the pushed short message, the dual-mode terminal generates a receipt for each successfully received short message. After the receipt reaches the platform, the short message is deleted in the mailbox after the mailbox learns that the specific short message is successfully received by the user through the analysis of the application layer signaling.

Step 1-9: generating a call ticket;

and generating a short message list of the user for account checking.

It should be noted that the sequence of each step in the first to fourth examples is only an exemplary description, and may be specifically adjusted according to actual situations.

Further, in an example, in a case that 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 embodiment, in the implementation design of sending a short message to a mobile user by a satellite-side one-number dual-network user, the route between an interworking gateway and a short message center (e.g., an MT short message center) is routed. The short message center can not check the home location of the calling number, only can inquire the roaming location of the called number, and send the short message to the local network of the roaming location through an IP or seventh signaling network; in the implementation design of sending short messages to a satellite side one-number dual-network user, a number 7 signaling route is routed through a BDMSC (satellite domain terminal office MSC) arranged in a satellite fusion gateway. The satellite domain end office accesses a No. 7 signaling network of a mobile telecommunication operator through the BDMSC, and short messages can be pushed to the BDMSC by short message centers of the operator all over the country through the No. 7 signaling network.

In the above embodiment, a terminal with dual-mode communication capability for mobile and satellite (the type includes professional terminal, smart phone, etc.) only needs to be equipped with identity authentication information (such as mobile SIM card) of a single mobile communication network; the terminal with the satellite single-mode communication capability is only provided with the identity authentication information of the satellite network, and can also realize communication with the terminal and the platform of the mobile communication network through the functions of number mapping and the like of the platform. Therefore, by constructing a satellite-ground converged communication platform, the UE side can be not changed, and a satellite user can access a mobile communication network through a universal short message gateway and can communicate with a mobile user by short messages; the UE side is only slightly changed, so that the common mobile operator user can receive and send the short message through a satellite channel without changing the number or the SIM card under the scene without covering a mobile communication network. By adding the UE of the satellite radio frequency, the global short message service can be realized on line through the satellite by activating the satellite short message value-added service by a large mobile phone user group, and the method has great value for professional markets such as vehicles, ships, seas and the like.

In conclusion, the above scheme has the following advantages:

the cost is low: in the special terminal solution, the terminal does not need to be modified. In the solution of the dual-mode terminal, only a few modifications are made to the common public mobile phones, and the cost is low.

The user experience is good: in the special terminal solution and the dual-mode terminal solution, the satellite short message and the mobile operator short message can be intercommunicated without changing the card and the number of a user.

Easy market expansion: for telecommunication operators, value added services fused with satellite short messages can be publicized to mobile phone users who support dual-mode terminals, and the services can be conveniently, quickly and rapidly opened. Only one value-added service is added for the user; for mobile operators, the service income is increased; for satellite operators, the market is rapidly expanded by using the customer base number of telecommunication operators.
