[0002] In the field of maritime safety, the safety of ship navigation always occupies a central position. Once a ship is in distress, other ships are urgently needed to intervene and carry out rescue operations.

[0003] In traditional ship distress communication, a distressed vessel sends distress information to a shore-based platform, which then assigns a corresponding rescue vessel to the distressed vessel based on the distress information, so that the rescue vessel can provide assistance to the distressed vessel.

[0004] When the distance between a distressed vessel and a shore-based platform exceeds a certain range, the shore-based platform will be unable to allocate a corresponding rescue vessel to the distressed vessel, resulting in poor timeliness of rescue operations. Summary of the Invention

Its main technical characteristic is connecting objects to networks through communication technologies, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection. Exemplarily, the terminal device in the embodiments of this application can be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that apply wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that can be worn directly on the body or integrated into a user's clothing or accessories.

[0185] Words such as "first", "second", etc. are used to distinguish identical or similar items with basically the same functions and roles. For example, the first value and the second value are only used to distinguish different values, and do not limit their order. Those skilled in the art can understand that words such as "first", "second", etc. do not limit the quantity and execution order, and words such as "first", "second", etc. do not necessarily limit to being different.

[0186] Words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design solution described as "exemplarily" or "for example" in this application should not be construed as being more preferred or more advantageous than other embodiments or design solutions.

[0187] "At least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are an "or" relationship. "At least one (item)" or its similar expression refers to any combination of these items, including any combination of single item (item) or plural items (items). For example, at least one (item) of a, b, or c can represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, c can be single or multiple.

[0188] To facilitate understanding of the technical solutions provided in the embodiments of this application, the following describes the communication fields to which the technical solutions provided in the embodiments of this application are applicable.

[0189] The technical solutions provided in this application are applicable to the field of international mobile communications, specifically to distress communications in the field of international mobile communications.

[0190] In the international mobile communications field, mobile communications are generally classified into emergency communications, security communications, routine communications, service communications, and distress communications, depending on the type of mobile communication service.

[0191] Emergency communications can be used for rapid rescue and coordination when mobile vehicles encounter serious disruptions to traffic safety or order.

[0192] Safe communication refers to all daily communication directly related to traffic safety. Safe communication can be used to transmit information such as weather information, traffic control information, or safety notices.

[0193] Routine communication refers to non-emergency and / or non-safety-related communication conducted by mobile vehicles during their daily operations. When the mobile vehicle is a ship, routine communication can be used for business contacts between the ship and shore-based management agencies, port authorities, cargo owners, or agents.

[0194] Business communications refer to communications related to various business activities in the operation of mobile transportation vehicles. These activities may include the buying and selling of goods, insurance transactions, or maintenance arrangements.

[0195] Distress communications can be used to provide assistance or coordinate efforts when a mobile vehicle encounters serious danger.

[0196] When the mobile transportation vehicle is a ship, distress communication can also be called ship distress communication.

[0197] Existing ship distress communications include radio communications or satellite communications.

[0198] Radio communications include, for example, very high frequency (VHF) radio communications, digital selective calling (DSC) communications, or medium frequency (MF) / high frequency (HF) radio communications.

[0199] Satellite communications include, for example, communications based on the International Maritime Satellite (Inmarsat) system and communications based on the International Search and Rescue Satellite (Cospas-Sarsat) system.

[0200] In radio and satellite communications, distressed vessels send distress signals to shore-based platforms, which then respond to the distress signals and coordinate efforts to rescue the distressed vessels.

[0201] In ship distress communication, as the distance between the distressed vessel and the shore-based platform increases, the strength and quality of the distress signal will gradually decrease. When the distance between the distressed vessel and the shore-based platform exceeds a certain range, the shore-based platform will be unable to allocate a corresponding rescue vessel to the distressed vessel, and the distress signal may even fail to be transmitted, resulting in poor timeliness of rescue for the distressed vessel.

[0202] In view of this, embodiments of this application provide a rescue communication method to solve the problem of poor timeliness in rescuing a second device (e.g., a distressed vessel).

[0203] The following combination Figure 1 The system architecture of the technical solutions shown in the embodiments of this application will be described. It is understood that the system architecture described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application and does not constitute a limitation on the technical solutions provided in the embodiments of this application.

[0204] Figure 1 This is a schematic diagram of a system architecture provided for an embodiment of this application. For example, as shown... Figure 1 As shown, it includes: a first device, a space network device, and N second devices. Here, N is an integer greater than and / or equal to 1.

[0205] The first device can communicate with space-based network equipment.

[0206] Optionally, the first device may communicate directly with the second device, or it may choose not to communicate directly with the second device. When the first device does not communicate directly with the second device, the space network device may communicate with the second device.

[0207] Optionally, if the first device can communicate directly with the second device, when the first device is in distress, the space network device can configure communication resources for the first device so that the first device and the second device can communicate directly based on the communication resources, thereby enabling the rescue of the first device.

[0208] Optionally, if the first device does not communicate directly with the second device, the space network device may communicate with the second device to request the second device to rescue the first device when the first device is in distress.

[0209] The communication between the first and second devices based on communication resources, as well as the request from the space network device for the second device to rescue the first device, do not require overall coordination and scheduling by the shore-based platform. Therefore, the timeliness of the rescue of the first device can be improved, avoiding the problem in related technologies where the shore-based platform cannot allocate a corresponding second device to the first device, resulting in poor timeliness of the rescue of the first device.
