[0024] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present application should fall within the scope of protection of the present application.
[0025] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0026] It should be noted that the satellite communication terminal in the embodiment of the present application may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device supporting satellite communication. For example, the satellite communication terminal in the embodiment of the present application may be a mobile phone, a tablet computer (Pad), a laptop computer, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, and an IoT terminal device, etc.
[0027] In order to facilitate the understanding of this application, the relevant technologies involved in this application are first introduced and explained below.
[0028] IoT data collection
[0029] IoT data collection can refer to the IoT business scenario of collecting monitoring information from sensors and other devices under test, analyzing and processing the data in the application system. The IoT architecture includes three main layers: perception layer, network layer and application layer. The perception layer mainly uses various sensors and actuators to perceive and control various parameters in the environment; the network layer is mainly responsible for transmitting the data collected by the perception layer to the application layer for processing; the application layer is mainly responsible for processing and applying the data transmitted from the network layer.
[0030] With the continuous development of satellite communication networks, information interaction between various fields and satellite communication networks is becoming more frequent, and data distribution is an important means of satellite data transmission.
[0031] As an example, satellite communication networks can be used for IoT data collection. For example, sensors can send data to satellite communication networks through satellite communication modules. The satellite communication network needs to distribute satellite communication data to the application system of the user corresponding to the satellite communication device for data analysis.
[0032] At present, the modes of data distribution mainly include push mode and publish-subscribe mode. The information push mode is a way for the information source to actively push information to users. The main advantage is good timeliness. The information source pushes constantly updated dynamic information to users in a timely manner; the main disadvantage is that the information source has a heavy task. The information source system must actively, quickly and continuously push a large amount of information to users.
[0033] If the push mode is used, the user needs to configure the data receiving address on the source side. When the data belonging to the user is updated, the update information will be sent to the configured data receiving address. However, when distributing satellite data for IoT data collection, there may be multiple users, each of whom has many application systems. The data generated by a sensor may need to be distributed to multiple application systems for simultaneous use. The data distribution strategy is relatively complex, and the data distribution method of the push mode cannot flexibly handle the distribution relationship, that is, the push mode is less flexible. In addition, the data distribution processing efficiency of the push mode is low when the data volume is large.
[0034] In the publish-subscribe model, the publisher publishes data to an intermediate message broker, and then the subscriber registers and subscribes to the message broker, which filters the data. The message broker usually performs a store-and-forward function to send data from the publisher to the subscriber. When new data is published, the subscriber will receive a notification and perform corresponding operations.
[0035] If the data distribution method of the publish-subscribe model is used, it is usually necessary to integrate various third-party data proxy tools, which increases the complexity of implementation and data distribution. In addition, when distributing satellite data for IoT data collection, the publish-subscribe model cannot meet the reliability and security of satellite data distribution.
[0036] According to the above description, in the push mode, the information source cannot flexibly handle the data distribution relationship; in the publish-subscribe mode, it is usually necessary to integrate a third-party data proxy tool, which increases the complexity of implementing the distribution system and the complexity of data distribution.
[0037] In response to the above problems, the present application provides a data distribution method, which is applied to a satellite data distribution platform, the satellite data distribution platform is connected to a satellite communication terminal and a user application system, the satellite communication terminal is used to collect target data, and the satellite data distribution platform is used to manage a first data distribution relationship between the satellite communication terminal and the user application system. The method includes: receiving target data from the satellite communication terminal through a satellite communication network; distributing the target data to the user application system according to the first data distribution relationship. The satellite data distribution platform provided by this solution can manage complex data distribution relationships (such as the first data distribution relationship) between terminal devices and user application systems, and accurately distribute target data to user application systems according to the first data distribution relationship, thereby improving the flexibility of data distribution and reducing the complexity of data distribution. The management device method in the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.
[0038] Figure 1 A flow chart of a data distribution method provided in an embodiment of the present application. The method is applied to a satellite data distribution platform, the satellite data distribution platform is connected to a satellite communication terminal and a user application system, the satellite communication terminal is used to collect target data, and the satellite data distribution platform is used to manage a first data distribution relationship between the satellite communication terminal and the user application system.
[0039] It should be noted that the target data may refer to the data to be distributed that the user needs the satellite communication terminal to collect.
[0040] It should be noted that the first data distribution relationship may refer to the mapping relationship between the data generated by the satellite terminal and multiple application systems established by the satellite data distribution platform. Of course, as user needs change, the first data distribution relationship may also be reconfigured, thereby flexibly implementing data distribution.
[0041] like Figure 1 As shown, the data distribution method 100 may include steps: S110-S120.
[0042] In step S110, target data is received from a satellite communication terminal via a satellite communication network.
[0043] Satellite communication network can refer to a communication system that uses artificial earth satellites as relay stations to transmit and forward radio wave signals. Satellite communication network can cover a large geographical area, including places that are difficult to reach by ground communication facilities, such as remote areas, at sea or in the air.
[0044] The satellite communication terminal may refer to any type of terminal equipment mentioned above.
[0045] In some implementations, the satellite communication terminal and the satellite data distribution platform can use short messages to transmit data through the satellite communication network. In some implementations, the user application system and the satellite data distribution platform can use short messages to transmit data. In other words, the satellite data distribution platform can be used to convert the target data into a data transmission format used when distributing the data.
[0046] As an example, after receiving the target data from the satellite communication terminal through the satellite communication network, the target data may be converted into an encrypted data format used in data distribution.
[0047] The embodiments of the present application do not impose any specific restrictions on the method of data encryption. For example, the target data may be encrypted using a symmetric encryption method; or, as another example, the target data may be encrypted using an asymmetric method.
[0048] In step S120, the target data is distributed to the user application system according to the first data distribution relationship.
[0049] It should be understood that the user application system may refer to the user's application system. The user application system may include one or more application systems, and the target data required by each application system may be the same or different, and this application does not make specific restrictions on this.
[0050] For example, the data generated by a satellite communication terminal may need to be distributed to multiple user application systems for simultaneous use, and the data required by each application system may also be different.
[0051] It should be noted that the satellite data distribution platform can also perform one or more of the following operations: collecting and storing distribution results of data distribution, providing a distribution failure compensation mechanism, establishing a data distribution relationship between the satellite communication terminal and the user application system, storing data to be distributed between the satellite communication terminal and the user application system, verifying the establishment of data distribution authority between the satellite communication terminal and the user application system, detecting the credibility of the satellite communication terminal and / or the user application system, etc.
[0052] For example, after the target data is distributed to the user application system, the distribution result of the target data may be received from the user application system and stored.
[0053] In some implementations, the target data distribution result information may include one or more of the following: data unique identifier, data distribution time, data distribution status, data distribution success or failure time.
[0054] For another example, the satellite data distribution platform can be used to monitor the distribution result of the target data. If the distribution result of the target data is a data distribution failure, the target data can be redistributed to the user application system according to the first data distribution relationship, thereby improving the reliability of data distribution.
[0055] For another example, before distributing the target data to the user application system, a first data distribution relationship between the satellite communication terminal and the user application system may be established based on the device information of the satellite communication terminal and the system information of the user application system.
[0056] In some implementations, the device information of the satellite communication terminal includes one or more of the following: device type, device name, device identifier, user, and device satellite number of the satellite communication terminal; in some implementations, the system information of the user application system includes one or more of the following: user name, user identifier, application system name, application system identifier, application system access key, application system access IP address, satellite data distribution device identifier information, and data distribution validity period. In some implementations, the distribution relationship information of the first data distribution relationship includes one or more of the following: user identifier, device identifier of the satellite communication terminal, user's application system identifier, distribution relationship expiration time, etc.
[0057] As another example, before distributing the target data to the user application system, the satellite data distribution platform may be used to store the data to be distributed (eg, target data) generated by the satellite communication terminal.
[0058] For another example, before distributing the target data to the user application system, the distribution authority of the target data can be verified based on the device information of the satellite communication terminal and the system information of the user application system. For example, by detecting the user name, user identifier, application system name, application system identifier, application system access key, application system access IP address, satellite data distribution device identifier information, data distribution validity period and other system information of the user application system, it can be determined whether the application system has the authority to receive the target data from the satellite communication terminal or distribute data (such as control instructions) to the satellite communication terminal.
[0059] For another example, before distributing the target data to the user application system, the satellite data distribution platform can receive the data subscription request from the user application system, which is used to subscribe to the target data; then, based on the system information of the user application system (such as the user's application system access key, the user's application system access IP address, etc.), the credibility of the data subscription request is detected. In other words, the satellite data distribution platform can be used to verify the identity of the recipient (such as the user application system) to ensure that only authorized entities can receive the target data. This verification mechanism helps to improve the security of data distribution.
[0060] It should be noted that the satellite data distribution platform in the embodiment of the present application can not only distribute the data generated by the satellite communication terminal to the user application system, but also distribute the control instructions of the user application system to the satellite communication terminal. The scheme of distributing the control instructions to the satellite communication terminal is described in detail below with reference to an example.
[0061] In some implementations, the satellite data distribution platform may receive a control instruction from a user application system, where the control instruction is used to control a satellite communication terminal; and then distribute the control instruction to the satellite communication terminal according to the first data distribution relationship.
[0062] In some implementations, the satellite data distribution platform may receive a distribution request for a control instruction from a user application system and verify the distribution relationship between the user application system and the satellite communication terminal. If no distribution relationship is found, the data distribution request initiated by the user application system is rejected.
[0063] In some implementations, the satellite data distribution platform may detect the distribution authority of the control instruction based on the system information of the user application system.
[0064] In some implementations, the satellite data distribution platform may receive and store control instructions sent from a user application system.
[0065] In some implementations, the satellite data distribution platform may convert the control instruction into a data transmission format used when distributing the control instruction, that is, convert the control instruction into a data transmission format that can be sent to the satellite communication terminal through the satellite communication network.
[0066] In some implementations, after the control instruction is distributed to the satellite communication terminal, the distribution result of the control instruction may be received from the satellite communication terminal and stored.
[0067] In some implementations, the control instruction distribution result information may include one or more of the following: a control instruction unique identifier, a control instruction distribution time, a control instruction distribution status, and a control instruction distribution success or failure time.
[0068] The following describes the embodiments of the present application in more detail with reference to specific examples. Figures 2 to 4 It is only to help those skilled in the art understand the embodiments of the present application, and is not intended to limit the embodiments of the present application to the specific values or specific scenarios illustrated.

[0070] The satellite communication terminal device may refer to a terminal device for collecting information of the Internet of Things through satellite communication.

It should be understood that the satellite communication data in the embodiment of the present application includes uplink communication data from the satellite communication terminal to the user application system and downlink communication data from the user application system to the satellite communication terminal.
[0071] The satellite data distribution platform can be used to manage the relationship between satellite communication terminal equipment, user information using the communication terminal equipment, and the application system built by the user. Furthermore, the satellite data distribution platform can be used to establish a data distribution relationship (such as the first data distribution relationship mentioned above) between the satellite communication terminal and the user's application system based on the relationship between the satellite communication terminal equipment, the user information using the communication terminal equipment, and the application system built by the user; when the satellite data distribution platform receives data reported by the satellite communication terminal through the satellite communication network, the data can be distributed to the corresponding user application system according to the distribution relationship configured by the satellite data distribution platform; when the user application system sends data (such as control instructions) to the terminal, the data can be distributed to the corresponding satellite terminal equipment according to the distribution relationship configured by the satellite data distribution platform.

[0082] The user application system can be used to receive data reported by satellite communication terminals through the satellite communication network, and analyze and apply the data according to business rules; in addition, users can also issue control instructions to designated satellite communication terminals in the application system, and the satellite data distribution platform will distribute the control instructions to the satellite communication terminals using the satellite communication network.
[0083] The user application system may include one or more application systems. For example, the user application system may include application system 1, application system 2, and application system 3. Each user system may include a data exchange unit. For example, application system 1 includes data exchange unit 1, application system 2 includes data exchange unit 2, and application system 3 includes data exchange unit 3. The user's application system may be used to carry an identity key to access the distribution execution unit of the satellite data distribution platform, and after passing the subscription security detection and distribution authority detection, receive the uplink data of all satellite communication terminals under the name of the application system, and may issue control instructions to the specified satellite communication terminal.
