[0039] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0040] Unless specifically stated otherwise, the relative arrangement of components and steps, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure.

[0041] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0042] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0043] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0044] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0045] Due to the rapid movement of low-orbit satellites, the terminal needs to continuously track low-orbit satellites, which will cause power waste and reduce the service life of the terminal. Since the terminal power is limited, it is necessary to reasonably design energy-saving mechanisms to extend battery life. After analysis, it is found that the terminal services in such remote areas have the following main characteristics: the frequency of receiving or sending data packets by the terminal is usually very low, the real-time requirements are not high, and the terminal location is relatively fixed.

[0046] The embodiments of the present disclosure propose a satellite communication method, system and related equipment, wherein, when there is no need for data transmission, the terminal does not synchronize with the low-orbit satellite but connects with the high-orbit satellite to effectively achieve energy saving; when there is a need for data transmission, the high-orbit satellite selects a suitable transmission path for the terminal.

[0047] Figure 1 FIG. 1 shows a schematic diagram of a network architecture according to some embodiments of the present disclosure. The network is a multi-layer satellite network. Figure 1 As shown, the terminal 11 can communicate with the high-orbit satellite 12 or the low-orbit satellite 13 through the Uu interface. The high-orbit satellite 12 and the low-orbit satellite 13 communicate with the ground station 14 through laser or microwave. The ground station 14 is connected to the core network 15 through optical fiber. Therefore, the terminal 11 can exchange data with the core network through the high-orbit satellite 12 or the low-orbit satellite 13.

[0048] Figure 2 FIG. 2 shows a schematic flow chart of a satellite communication method according to some embodiments of the present disclosure. Figure 2 As shown, the satellite communication method of this embodiment includes steps S202 to S206.

[0049] In step S202, in a designated mode, the terminal monitors signaling from a high-orbit satellite, wherein the terminal in the designated mode does not track a low-orbit satellite.

[0050] The terminal in the designated mode does not track the low-orbit satellite, so there is no need to keep synchronization with the low-orbit satellite in real time. The designated mode is, for example, a sleep mode, so that the terminal operates in a low-power state.

[0051] The terminal can access the high-orbit satellite in advance through random access and other processes. The terminal can monitor the signaling from the high-orbit satellite in the specified mode. Since the high-orbit satellite is stationary relative to the ground, the terminal does not need to continuously track the high-orbit satellite or frequently switch between satellites. Compared with the state where it needs to track low-orbit satellites, the terminal in the specified mode can achieve energy saving.

[0052] In the specified mode, the terminal can only enable the function for receiving signaling from the high-orbit satellite and disable other functions, thereby saving more energy consumption.

[0053] In some embodiments, the terminal is a fixed terminal. The terminal may be an Internet of Things device for collecting environmental data.

[0054] In step S204, the high-orbit satellite sends a first request to the terminal. The first request includes information of a designated satellite, where the designated satellite is a high-orbit satellite or a low-orbit satellite.

[0055] The high-orbit satellite can receive a data transmission request sent by the network side, so as to send a first request in response to the data transmission request. The data transmission request, for example, includes at least one of the identification of the high-orbit satellite, the identification of the terminal, the location of the terminal, and the service type. The identification of the high-orbit satellite is used to indicate the recipient of the data transmission request. The identification of the terminal and the location of the terminal are used to indicate the terminal for which the service to be initiated is targeted. The service type can be used by the high-orbit satellite to decide the transmission path to be selected. Of course, this information may also not be included in the data transmission request. The high-orbit satellite can obtain it through other means, or use default values, etc., which will not be repeated here.

[0056] The high-orbit satellite may indicate, through the first request, a data transmission path, that is, whether to transmit the data through the high-orbit satellite or through the low-orbit satellite.

[0057] In some embodiments, the designated satellite is determined according to the service type. That is, according to the service type, it is determined whether to transmit data through a high-orbit satellite or a low-orbit satellite. The designated satellite can be determined by the high-orbit satellite, or it can be determined by the network side and then notified to the high-orbit satellite. The first request, for example, carries the identifier of the designated satellite, access resources, etc.

[0058] For example, the transmission paths may be differentiated according to the data rate of the service type. In some embodiments, when the data rate of the service type is lower than a first threshold, the designated satellite is a high-orbit satellite; when the data rate of the service type is higher than a second threshold, the designated satellite is a low-orbit satellite.

[0059] The first threshold and the second threshold may be the same or different. When they are different, the first threshold may be greater than or less than the second threshold. In this case, for a service type that meets the conditions of being lower than the first threshold and higher than the second threshold, the transmission path to be used may be further decided in combination with other information.

[0060] The data rate of a service type can be the average transmission rate of the service type, the required average transmission rate, etc. Since low-orbit satellites have low latency and large capacity, they are more suitable for high-rate services. For low-rate services, the capacity of high-orbit satellites is sufficient to support data transmission, so they can also provide services to terminals.

[0061] In addition, the transmission path may also be determined according to the type of data carried by the service. In some embodiments, when the service type is text transmission or voice transmission, the designated satellite is the high-orbit satellite; when the service type is image transmission or video transmission with a resolution greater than a third threshold, the designated satellite is a low-orbit satellite.

[0062] That is, text and voice services have relatively low requirements for latency and data volume, so they can be transmitted through high-orbit satellites; while for high-resolution images and videos, the requirements for latency and data volume are relatively high, so they can be transmitted through low-orbit satellites.

[0063] In response to the first request, the terminal exits the designated mode. After the terminal receives the first request, the terminal may, for example, switch from the designated mode to another mode. For example, if the designated mode is the first mode, the terminal may switch from the first mode to the second mode. In some embodiments, if the designated mode is the sleep mode, the first request may be regarded as a wake-up request. After receiving the first request, the terminal switches from the sleep mode to another mode, such as the wake-up mode.

[0064] After exiting the specified mode, the terminal can operate at a higher power than the operating power in the specified mode, that is, it can operate more functions. For example, in the specified mode, the terminal does not track low-orbit satellites, but after exiting the specified mode, the terminal is allowed to track low-orbit satellites and communicate with low-orbit satellites when necessary. Thus, the data transmission path can be flexibly selected.

[0065] In step S206, the terminal sends data to the network side via the designated satellite.

[0066] After the terminal exits the designated mode, it sends data to the network side through the designated satellite. For example, in S206-1, when the designated satellite is a high-orbit satellite, the terminal sends data through the high-orbit satellite. For example, in S206-2, when the designated satellite is a low-orbit satellite, the terminal sends data through the low-orbit satellite.

[0067] After the terminal has sent the data, the terminal can re-enter the specified mode, for example, re-enter the sleep mode.

[0068] Through the above embodiments, when there is no current demand for data transmission, the terminal does not need to maintain synchronization with the low-orbit satellite, thereby effectively saving energy and extending the service life of the terminal; when there is a current demand for data transmission, the high-orbit satellite indicates the data transmission path to the terminal, thereby improving the resilience and availability of the network.

[0069] The following describes the interaction process between the terminal and the satellite by taking the designated satellites as a high-orbit satellite and a low-orbit satellite as examples.

[0070] Figure 3 FIG. 2 shows a schematic flow chart of a satellite communication method according to other embodiments of the present disclosure. Figure 3 As shown, the satellite communication method of this embodiment includes steps S302 to S306.

[0071] In step S302, the high-orbit satellite receives a data transmission request sent by the network side.

[0072] In step S304, the high-orbit satellite sends a first request to the terminal in the designated mode. The first request includes, for example, at least one of an identifier of the high-orbit satellite, an identifier of the terminal, an identifier of a service type, and an identifier of a beam of the high-orbit satellite.

[0073] In the first request, the identifier of the high-orbit satellite can indicate which satellite the terminal transmits data through; the identifier of the terminal is used to indicate the recipient of the first request; the identifier of the service type is used to notify the terminal of the service type or data type of the data to be transmitted; and the beam identifier is used to indicate the beam used by the terminal when transmitting data.

[0074] After receiving the request, the terminal determines that data needs to be sent via a high-orbit satellite.

[0075] In step S306, in response to the first request, the terminal exits the designated mode and sends data to the network side through the high-orbit satellite. That is, the high-orbit satellite receives the data sent by the terminal and sends the data to the network side.

[0076] Then, the terminal returns to the specified state.

[0077] Through the above embodiments, when there is no data transmission demand at present, the terminal does not need to maintain synchronization with the low-orbit satellite, thereby effectively saving energy and extending the service life of the terminal; when there is a data transmission demand at present and the transmission can be performed by the high-orbit satellite, the terminal directly transmits data through the high-orbit satellite, thereby further achieving energy saving.

[0078] Figure 4 FIG. 2 shows a schematic flow chart of a satellite communication method according to other embodiments of the present disclosure. Figure 4 As shown, the satellite communication method of this embodiment includes steps S402 to S414.

[0079] In step S402, the high-orbit satellite receives a data transmission request sent by the network side. Based on the data transmission request, the high-orbit satellite determines that the terminal needs to transmit data via the low-orbit satellite.

[0080] In step S404, the high-orbit satellite sends a second request (eg, a resource request) to the low-orbit satellite, where the second request includes at least one of an identifier of the high-orbit satellite, an identifier of the terminal, and a service type.

[0081] The second request is used to request the low-orbit satellite to prepare relevant resources for data transmission.

[0082] In step S406, the high-orbit satellite receives a response to the second request sent by the low-orbit satellite, such as a response to the resource request, wherein the response includes at least one of an identifier of the low-orbit satellite, a beam identifier of the low-orbit satellite, and time-frequency resource information.

[0083] The response sent by the low-orbit satellite is used to notify the high-orbit satellite of the prepared resources.

[0084] In step S408, the high-orbit satellite sends a first request to the terminal in the specified mode. The first request includes, for example, the identifier of the low-orbit satellite, and at least one of the identifier of the high-orbit satellite, the identifier of the terminal, the identifier of the service type, the beam identifier of the low-orbit satellite, and the time-frequency resource information.

[0085] In the first request, the identifier of the low-orbit satellite can indicate which satellite the terminal transmits data through; the identifier of the high-orbit satellite is used to indicate the sender of the first request; the identifier of the terminal is used to indicate the recipient of the first request; the identifier of the service type is used to notify the terminal of the service type or data type of the data to be transmitted; the beam identifier is used to indicate the beam used by the terminal when transmitting data; and the time-frequency resource information is used to indicate the time-frequency resources used by the terminal when accessing the low-orbit satellite or transmitting data.

[0086] After receiving the request, the terminal determines that data needs to be sent via a low-orbit satellite.

[0087] In step S410, in response to the first request, the terminal exits the designated mode, disconnects from the high-orbit satellite, and accesses the low-orbit satellite. The low-orbit satellite is the low-orbit satellite indicated by the first request. The terminal accesses the low-orbit satellite, for example, through a random access process.

[0088] In step S412, the terminal sends data to the network side via the low-orbit satellite. That is, the low-orbit satellite receives the data sent by the terminal and sends the data to the network side.

[0089] In step S414, the terminal disconnects from the low-orbit satellite, connects to the high-orbit satellite, and enters a designated mode.

[0090] Through the above embodiments, when there is no data transmission demand at present, the terminal does not need to maintain synchronization with the low-orbit satellite, thereby effectively saving energy and extending the service life of the terminal; when there is a data transmission demand at present, and the transmission needs to be completed through the low-orbit satellite, the terminal can access the low-orbit satellite and complete the data transmission, and re-access the high-orbit satellite after the transmission is completed. Therefore, it is possible to save energy consumption as much as possible while meeting the data transmission demand.

[0091] The above is an introduction to the embodiments of the methods disclosed in the present invention. The following describes the apparatus for executing the above methods.
