[0022] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order for those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments, and all should belong to the protection scope of the present application.

[0024] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-mentioned drawings are applicable to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that the terms thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0025] It should also be noted that the division of the plurality of embodiments in the present application is only for the convenience of description, and should not constitute a special limitation. The features in various embodiments can be combined and mutually referenced without contradiction.

[0026] As Figure 1As shown, the first embodiment of the present application proposes a ship communication link establishment method based on perception control, for example, including: step S1, detecting the communication link between the current satellite and the target ship, and judging whether link switching is needed according to the satellite orbit information and the ship position information; step S2, if switching is needed, judging whether there is a next service satellite that can be switched and accessed in the coverage range of the current satellite; step S3, if there is, switching to the next service satellite, and if there is not, the target ship applies for perception control, and obtains the accessible ship information of the preset sea area through the perception control signal; step S4, according to the accessible ship information, selecting the optimal ship from all the alternative accessible ships through an adaptive selection algorithm to establish an inter-ship cooperative transmission link; and step S5, releasing the original communication link, and realizing the data transmission between the current satellite and the target ship through the inter-ship cooperative transmission link.

[0027] Specifically, in combination with Figure 2 As shown, the ship within the satellite coverage range can establish a communication link with the 6G core network through a low earth orbit satellite to obtain the Internet information required for maritime business. When the shipborne 6G ship leaves the satellite coverage range, and due to the high dynamic nature of the low earth orbit satellite and the small coverage range of a single satellite, it cannot be switched to the next service satellite in the discontinuous low earth orbit satellite coverage range.

[0028] Firstly, through detection and monitoring of the current link, it is judged whether the current satellite-ship communication link needs to be switched. The basis for the judgment is to predict the satellite orbit information through the satellite ephemeris information and the ship's own position information to determine whether it is about to leave the coverage range of the current satellite. If so, switching needs to be applied to maintain the continuity of the communication service.

[0029] After applying for switching, it is judged whether there is a next service satellite that can be switched and accessed in the current range. If there is, switch to the next serviceable low earth orbit satellite in the current coverage range. If there is not, perception control needs to be applied. Through the perception control signal, the accessible ship information of the nearby sea area is obtained, and then the optimal ship is selected from all the alternative accessible ships through an adaptive selection algorithm to establish an inter-ship communication link. Finally, the original communication link is released, and data transmission is performed based on the inter-ship cooperative transmission link.

[0030] Further, for example, the perception signal is configured according to the perception service request or the perception QoS, and the perception signal includes reference signals, synchronization signals, data signals, etc. The perception signal configuration includes the configuration of the time domain, frequency domain and spatial domain resources of the perception signal. Then the perception measurement value required by the perception service request and the measurement configuration are determined, and the perception signal is received and transmitted by using the perception method based on the Uu interface and the perception method based on the sidelink.

[0031] Further, as Figure 3As shown, the gray ship is a to-be-accessed ship in a non-continuous low-orbit satellite coverage area. First, the to-be-accessed ship performs beam scanning through the sensing control signal transceiver, detects all ships in the vicinity within the communication range, and ships outside the scanning coverage cannot establish an inter-ship transmission link due to the limitation of communication signal transmission. Then, the accessible ships with idle channels and within the communication range send each index value involved in the judgment condition to the to-be-accessed ship. Finally, the ship sets the weight of each index value by combining the current business demand and the marine environment, calculates the final weighted index value of each accessible ship, and selects the optimal ship to establish an inter-ship link.

[0032] Further, after the ship successfully establishes an inter-ship cooperative link with the next-hop accessible optimal ship, if the next-hop ship is within the low-orbit satellite coverage range, it does not need to continue to find the next-hop accessible optimal ship. If the next-hop ship is also located in the non-continuous coverage area of the low-orbit satellite, the same adaptive cooperative selection algorithm is adopted to select the next-hop accessible optimal ship until a transmission link with the low-orbit satellite is successfully established.

[0033] The inter-ship cooperative link is a temporary link, and the next-hop accessible ship is equivalent to a temporary relay node, which realizes flexible and fast networking between ships by adopting a distributed networking manner, that is, "use and connect", and when the data transmission or reception is completed, the temporarily occupied link resources can be released, thereby realizing efficient utilization of communication resources. The distributed cooperative temporary networking does not need to be concentratedly forwarded and managed through a base station, and each ship is equivalent to an independent node, thereby reducing the forwarding overhead and transmission delay of intermediate signaling. Through flexible and fast networking between ships, the service continuity problem of the non-continuous coverage area of the low-orbit satellite is solved, and stable transmission of the marine shipborne 6G signal is guaranteed.

[0034] In addition, the second embodiment of the present application also proposes a ship communication link establishment device based on sensing control, which comprises a communication link detection module, a switching and access judgment module, a sensing control module, a cooperative transmission link establishment module, and a data transmission module.

[0036] Further, the ship communication link establishment device based on perception control further comprises an accessible ship searching module, which is used for not continuing to search for a next-hop accessible ship if the optimal ship is in the coverage range of the current satellite, and continuing to apply for perception control by the optimal ship and repeating the adaptive selection algorithm to select a next-hop accessible ship until a transmission link is successfully established with the current satellite if the optimal ship is not in the coverage range of the current satellite.
