[0010] [Research Period] December 1, 2024 to December 31, 2025 Background Technology

[0011] The sea areas in which ships navigate can be distinguished based on their distance from land. Although distance standards vary from country to country, sea areas are generally divided into nearshore waters (or coastal waters), territorial sea, and high seas based on their distance from land. Nearshore waters (or coastal waters) are areas where economic or fishing activities are conducted; they are the sea areas closer to land than the territorial sea. The territorial sea extends 12 nautical miles from the coastline into the ocean. The high seas are all sea areas outside the territorial sea and exclusive economic zone, and are not subject to the sovereignty of any single state. The wireless communication frequencies (e.g., frequencies used for communication with radio equipment) or frequency bands used by ships vary according to the laws of different countries, depending on the sea area. When a ship changes sea areas during navigation, users of the ship's radio equipment must manually change to wireless communication frequencies that comply with communication regulations. Summary of the Invention

[0012] Technical methods for solving problems

[0013] A control device for a communication mode based on a ship position control radio device according to an embodiment includes: a memory for storing instructions; a processor for executing the instructions stored in the memory; and a communication circuit that communicates with a wireless relay device via metal body communication, which uses the ship's metal body as a medium to transmit signals. When the processor executes the instructions, the control device: acquires position information about the ship's maritime position; when it senses, based on the ship's position information, that the ship's maritime position has moved from a first sea area corresponding to a first communication mode to a second sea area corresponding to a second communication mode, identifies communication configuration information corresponding to the second communication mode; and sends the communication configuration information corresponding to the second communication mode to the wireless relay device, so that the wireless relay device sends the communication configuration information corresponding to the second communication mode to one or more radio devices, wherein the first communication mode is a mode having a communication configuration different from the second communication mode.

[0014] The communication configuration information includes one or more of the following: the frequency band for wireless communication in the second sea area, the frequency for wireless communication, and the signal strength of wireless communication.

[0015] When the processor executes instructions, the control device causes one or more radio devices to change the frequency used for communication between radio devices to the frequency used for wireless communication in response to communication configuration information received from the wireless relay device.

[0016] The first communication mode represents the communication mode when the ship's maritime position is within the territorial sea. The second communication mode represents the communication mode when the ship's maritime position is in an area closer to land than the territorial sea and communicating with communication facilities in a port on land. When the processor executes the instruction, the control device causes one or more radio devices to change the frequency used for communication between radio devices to the frequency used for wireless communication with the port's communication facilities in response to communication configuration information received from the wireless relay device.

[0017] In one embodiment, the first communication mode represents the communication mode when the ship's position at sea is in territorial waters, and the second communication mode represents the communication mode when the ship's position at sea is in the high seas.

[0020] When the processor executes instructions, the control device causes one or more radio devices to adjust the signal strength used for radio device communication to the signal strength of wireless communication contained in the received communication configuration information in response to communication configuration information received from a wireless relay device.

[0021] Location information is obtained from GPS (global positioning system) sensors or determined using a base station-based network.

[0022] When the processor executes instructions, the control device generates an alarm request signal when it senses that the ship's position at sea has moved from the first sea area to the second sea area. This alarm request signal is then sent to a wireless relay device, which in turn sends the alarm request signal to one or more wireless devices.

[0023] A control method for controlling the communication mode of a radio device using a control device according to an embodiment includes the following steps: acquiring location information about the ship's maritime position; when the ship's maritime position is sensed to have moved from a first sea area corresponding to a first communication mode to a second sea area corresponding to a second communication mode based on the ship's location information, identifying communication configuration information corresponding to the second communication mode; and causing a wireless relay device to send the communication configuration information corresponding to the second communication mode to one or more radio devices, wherein the communication configuration information corresponding to the second communication mode is sent to the wireless relay device, the first communication mode is a mode having a communication configuration different from the second communication mode, and the wireless relay device performs metal body communication using the ship's metal body as a medium to transmit signals.

[0024] The control method further includes the step of causing one or more radio devices to change the frequency used for communication between radio devices to a frequency used for wireless communication in response to communication configuration information received from a wireless relay device.

[0025] The first communication mode represents the communication mode when the ship's maritime position is within territorial waters, and the second communication mode represents the communication mode for communicating with communication facilities in a port on land when the ship's maritime position is in an area closer to land than territorial waters. The step of changing the frequency for wireless communication may include the following steps: causing one or more radio devices to change the frequency used for communication between radio devices to a frequency used for wireless communication with communication facilities in the port in response to communication configuration information received from a wireless relay device.

[0026] In one embodiment, the first communication mode represents the communication mode when the ship's position at sea is within territorial waters, and the second communication mode represents the communication mode when the ship's position at sea is on the high seas. The step of changing the frequency for wireless communication may include the following steps: causing one or more radio devices to change the frequency used for communication between radio devices to a frequency used for wireless communication on the high seas in response to communication configuration information received from a wireless relay device.

[0027] In one embodiment, the first communication mode represents the communication mode when the ship's position at sea is on the high seas, and the second communication mode represents the communication mode when the ship's position at sea is in territorial waters. The step of changing the frequency for wireless communication may include the following steps: causing one or more radio devices to change the frequency used for communication between radio devices to a frequency used for wireless communication in territorial waters in response to communication configuration information received from a wireless relay device.

[0028] The control method further includes the step of causing one or more radio devices to change the frequency used for communication between the radio devices and the wireless relay device to a frequency used for wireless communication in response to communication configuration information received from the wireless relay device.

Terms commonly used, such as those defined in dictionaries, shall be understood as having the meaning in the relevant technical context and, unless explicitly defined in this specification, shall not be interpreted as having an idealized or overly formal meaning.

[0042] The embodiments will now be described in detail with reference to the accompanying drawings. In the description of the examples with reference to the drawings, the same parts are referred to by the same reference numerals, and repeated descriptions are omitted.

[0043] Figure 1The accompanying drawing illustrates how a control device controls the communication mode of a radio device according to an embodiment.

[0044] Reference Figure 1 Ships (e.g.: Figure 2 The radio equipment 130 used on the vessel (200) can use different frequency bands for wireless communication depending on the sea area where the vessel is located. Different countries have different laws specifying the frequency bands and frequencies that the radio equipment 130 can use for wireless communication. When the sea area where the vessel is located changes, the control device 110 can cause the radio equipment 130 to change the frequency used for wireless communication to the frequency specified for the sea area where the vessel is located. The control device 110 can reduce the inconvenience of the user having to manually change the wireless communication frequency band of the radio equipment 130 when the vessel's sea area changes.

[0045] The control device 110 can send communication configuration information to the wireless relay device 120, so that the wireless relay device 120 can send the communication configuration information to the radio device 130.

[0046] The control device 110 can acquire the location information of the sea area where the vessel is located and identify communication configuration information based on the vessel's location information. For example, when the control device 110 senses that the vessel's location has moved from a first sea area corresponding to a first communication mode (e.g., territorial waters) to a second sea area corresponding to a second communication mode (e.g., the high seas) based on the vessel's location information, the control device 110 can identify the communication configuration information corresponding to the second communication mode. The control device 110 can acquire the vessel's location information from a GPS sensor or determine the vessel's location information using a base station-based network. For example, the control device 110 can use a land-based base station to determine the vessel's maritime position based on triangulation. The communication configuration information may include one or more of the following: the wireless communication frequency band used in the second sea area, the frequency used for wireless communication, and the signal strength of the wireless communication.

[0047] The control device 110 can send the communication configuration information corresponding to the second communication mode to the wireless relay device 120, so that the wireless relay device 120 can send the communication configuration information corresponding to the second communication mode to one or more radio devices 130.

[0048] According to one embodiment, when a vessel's maritime position is sensed to have moved from a first sea area to a second sea area, the control device 110 can generate an alarm request signal (e.g., "Entered Korean territorial waters") to cause the radio device 130 to provide an alarm informing it of the change in sea area. The control device 110 can then send the alarm request signal to a wireless relay device 120, which in turn sends the alarm request signal to one or more radio devices 130.

[0049] The wireless relay device 120 can communicate simultaneously or separately with the control device 110 and the radio device 130. The wireless relay device 120 can perform metal-body communication to control the communication modes of the control device 110 and the radio device 130. For example, the wireless relay device 120 can receive communication configuration information corresponding to a second communication mode (e.g., the communication mode of the radio device 130 when the ship enters territorial waters) from the control device 110 via metal-body communication. The wireless relay device 120 can also communicate with the control device 110 via metal-body communication, where the ship's metal body is used as the medium for signal transmission.

[0050] According to one embodiment, the wireless repeater 120 can communicate with other wireless repeaters (not shown) via a metallic body. For example, a first wireless repeater (e.g.: Figure 2 The wireless repeater 211 can transmit communication configuration information corresponding to the second communication mode to the second wireless repeater (e.g., through metal body communication). Figure 2 The wireless relay device 222), here the communication configuration information corresponding to the second communication mode, is received from the control device 110 via metal-body communication. Metal-body communication will... Figure 2 A more detailed explanation follows.

[0051] According to one embodiment, the radio device 130 can receive communication configuration information from the wireless relay device 120. The radio device 130 can use the received communication configuration information to change one or more of the frequency band, wireless communication frequency, or wireless communication signal strength of the radio device 130 for wireless communication. Figure 3 and Figure 4 The lieutenant general will explain in more detail the method of changing the communication mode of the radio device 130 using the communication configuration information received by the radio device 130.

[0052] Figure 2 The accompanying drawings illustrate onboard communication using a wireless relay device according to an embodiment.

[0053] Reference Figure 2 The radio equipment used within the vessel 200 may include a first radio equipment 212 and a second radio equipment 221, and the wireless relay equipment may include a first wireless relay equipment 211 and a second wireless relay equipment 222. The first radio equipment 212 can communicate wirelessly with the first wireless relay equipment 211 in a first wireless communication area 210; the second radio equipment 221 can communicate wirelessly with the second wireless relay equipment 222 in a second wireless communication area 220.

[0054] A radio device can adjust the frequency used for wireless communication between radio devices based on communication configuration information received from a wireless relay device. In response to receiving communication configuration information from the wireless relay device, the radio device can change the frequency used for communication between the radio devices to the frequency used for wireless communication. For example, a first radio device 212 receives communication configuration information from a first wireless relay device 211, and in response to the received communication configuration information, changes one or more of the frequency band, frequency used for wireless communication, and wireless communication strength of the first radio device 212 to the frequency band, frequency, and wireless communication strength contained in the received communication configuration information.

[0055] According to one embodiment, a first wireless relay device 211 and a second wireless relay device 222 may be installed on a ship 200 made of metal. The first wireless relay device 211, the second wireless relay device 222, and a control device (not shown) can communicate via the metal body of the ship 200's metal structure.

[0056] Metallic communication can be a method of communication using a metallic body as a medium. A wireless relay device (e.g., a first wireless relay device 211) can receive signals and / or data from a terminal communication device (e.g., the first wireless relay device 211) and use metal as a medium to transmit the received signals and data to another wireless relay device (e.g., a second wireless relay device 222). For example, wireless relay devices 210 and 220 can effectively conduct wireless communication using metal as a medium in communication dead zones such as ships, containers, and semi-trailers where wireless communication is difficult due to metal. Wireless relay devices 211 and 222 may include an antenna device attached to the metallic hull of the ship 200, forming an electromagnetic field on the metallic hull and transmitting the data from the data processing unit of the control device (e.g., [missing information]). Figure 6 The processor 620 receives communication configuration information, which is carried in an electromagnetic field and transmitted using metal. The antenna devices of the wireless relay devices 210 and 220 can receive signals and / or data transmitted to the electromagnetic field through the metal, and the wireless relay devices 210 and 220 can transmit the received signals and / or data to the terminal communication device through their own communication channels.

[0057] The principle of transmitting signals and / or data through a metallic medium is explained below. The metallic medium can be a ship's hull plate or a skeletal structure. Furthermore, the explanation will distinguish between cases where the metallic medium is a magnet and cases where it is a diamagnetic material.

[0058] When the metallic medium is a magnet

[0059] The conductive layer of the first antenna generates an electromagnetic field in the dielectric layer. This electromagnetic field then forms a dominant electromagnetic field within the metallic medium, which serves as the transmission medium. Within this formed electromagnetic field, the electromagnetic field E1 propagates perpendicularly through the opening of the first antenna into the metallic medium. The propagating electromagnetic field E1 then forms a dominant electromagnetic field B within the metallic medium.

[0060] At this point, according to the reversible theory, the second antenna at the receiving end receives energy from the electromagnetic field formed within the metallic medium, based on a similar structure and principle. This process involves the change in energy B being transmitted through the opening of the second antenna in the dielectric layer to the electromagnetic field E2, which is dominated by the electric field.

[0061] In communication using a metallic medium (also known as metallic communication), the impedance changes very little even if the shape and size of the metallic medium change, because the magnetic field dominates. Furthermore, since the permeability of the metallic medium is greater than that of air, the radio transmission efficiency is superior to communication systems that propagate through air. Therefore, communication distances via magnetic metallic media are longer than those via air-based magnetic field communication. To create an electromagnetic field dominated by the magnetic field, the design of the resonant and circuit components of the wireless repeater should ensure that they generate an electromagnetic field of a certain magnitude within the metallic medium.

[0062] By creating an electromagnetic field within a metallic medium, energy can even be transferred to a resonator located at a certain distance from the metallic medium. The electromagnetic field formed within the metallic medium is dominated by a magnetic field; therefore, the electric field radiates from the metallic medium. This allows an antenna resonating at its operating frequency to receive energy within a certain distance of the metallic medium.

[0063] The dielectric layer of the first or second antenna can reduce the thickness and size of the resonant part, and form an electromagnetic field B dominated by the magnetic field in the metallic medium to ensure sufficient energy transfer.

[0064] When the metallic medium is a paramagnetic or diamagnetic material

[0065] The current that abruptly transitions to the conductive layer creates an electromagnetic field E1 dominated by the electric field within the metallic medium. At this point, the electric field radiated from the opening cannot create an electromagnetic field B dominated by the magnetic field within the metallic medium. This is because the permeability of paramagnetic and diamagnetic materials is similar to that of air. Therefore, the propagation of the magnetic field in air by paramagnetic and diamagnetic metallic media is not as strong as that in ferromagnetic materials, but rather similar to that in air. In other words, the propagation distance in air and inside the metallic medium is similar.

[0066] Pure iron, as a ferromagnetic material, has a permeability of 4000 to 5000, while aluminum, as a paramagnetic material, or silver (Ag), as a diamagnetic material, has a permeability of approximately 1.0. Therefore, the intensity of the magnetic field propagation within the metal will differ. In this case, through the action of the current induced by the metallic medium, a signal can be transmitted from the conductive layer of the antenna to the layer in contact with the metallic medium to the receiver. At this time, an electromagnetic field radiated from the opening surface is induced in the metallic body, thereby transmitting signals or electricity.

[0067] like Figure 2 In structures primarily composed of metal, such as the ship 200 shown (e.g., liquefied natural gas carrier), radio waves are reflected and / or attenuated because they cannot penetrate metal, resulting in unreliable wireless communication. This creates wireless communication dead zones within the metal structure, where wireless communication is difficult or impossible. For example, communication dead zones may occur in areas such as the pipe duct, engine room, bosun store, engine control room (ECR), and bow thruster room of an LNG ship. In such cases, relaying is required between areas where radio waves are easily radiated in the air, such as the cargo control room (CCR), bridge, and compass deck, or upper deck, and these wireless communication dead zones. Wireless relay devices 210 and 220, according to one embodiment, can function as relay devices, facilitating communication between areas with good wireless communication and wireless communication dead zones.

[0068] Wireless relay devices can be controlled from control devices (e.g.: Figure 1 The control device 110 receives communication configuration information. This communication configuration information may refer to the communication configuration information identified by the control device in the changed sea area when the sea area to which the vessel 200 belongs changes. The wireless relay device can transmit the received communication configuration information to surrounding wireless devices. For example, the first wireless relay device 211 can transmit the communication configuration information received from the control device to the first wireless device 212, while the second wireless relay device 222 can transmit the communication configuration information received from the first wireless relay device 211 to the second wireless device 221.

[0069] Figure 3 The accompanying drawings illustrate a change in the communication configuration of a radio device when a vessel enters the territorial waters of another country from the high seas, according to one embodiment.

[0070] Reference Figure 3According to one embodiment, the sea area can be divided into a first country's territorial sea 310, the high seas 320, and a second country's territorial sea 330. The first country's territorial sea 310 and the high seas 320 can be divided based on a first boundary line 315; the second country's territorial sea 330 and the high seas 320 can be divided based on a second boundary line 325. A vessel located at a first position 301 in the high seas 320 can enter the first country's territorial sea 310 or the second country's territorial sea 330. The control device can determine whether a vessel has entered the first country's territorial sea 310, the high seas 320, or the second country's territorial sea 330 based on position information received from a GPS sensor.

[0071] In one embodiment, when a vessel located at a first position 301 in the high seas 320 enters a second position 302 in the territorial waters of a first country 310, the control device can cause one or more radio devices on the vessel to change the frequency used for communication between radio devices to a frequency used for wireless communication in the territorial waters of the first country 310 in response to communication configuration information received from a wireless relay device. For example, when a vessel located at a first position 301 in the high seas 320 enters the territorial waters of South Korea, the control device can cause the radio devices on the vessel to change the frequency used for communication between radio devices to 156.600 MHz in response to communication configuration information of the territorial waters of South Korea received from a wireless relay device.

[0072] According to one embodiment, when a vessel located at a first position 301 in the high seas 320 enters a third position 303 in the territorial waters of a second country 330, a control device can cause one or more radio devices on the vessel to change the frequency used for communication between radio devices to a frequency used for wireless communication in the territorial waters of the second country 330 in response to communication configuration information received from a wireless relay device. For example, when a vessel located at a first position 301 in the high seas 320 enters Japanese territorial waters, the control device can cause the radio devices on the vessel to change the frequency used for communication between radio devices to 156.700 MHz in response to communication configuration information of the Japanese territorial waters received from a wireless relay device.

[0073] Figure 4 The accompanying drawings illustrate how the communication configuration of a radio device changes when a ship enters different sea areas according to an embodiment.

[0074] Reference Figure 4 The sea area can be divided into nearshore waters 410 (or coastal waters), territorial sea 420, and high seas 430. Nearshore waters 410 and territorial sea 420 can be demarcated based on the first boundary line 415; territorial sea 420 and high seas 430 can be demarcated based on the second boundary line 425. Vessels located in territorial sea 420 (e.g., Figure 2 Vessels (200) may enter nearshore waters (410) or the high seas (430). Alternatively, vessels located in the high seas (430) may enter the territorial sea (420). Control devices (e.g.: Figure 1The control device 110 can determine whether the vessel has entered the nearshore waters 410, territorial sea 420 or high seas 430 based on the location information received from the GPS sensor (not shown).

[0075] When the sea area where a vessel is located changes due to the vessel's movement, the control device can cause the radio devices to change the frequency used for wireless communication. For example, when the control device senses that the vessel has entered a second sea area from a first sea area, it can identify a second communication mode. The control device can send communication configuration information corresponding to the second communication mode to a wireless relay device, which then sends the communication configuration information corresponding to the second communication mode to one or more radio devices. The wireless relay device can then send the received communication configuration information to one or more radio devices. The radio device receiving the communication configuration information can, in response to the information received from the wireless relay device, change the frequency used for communication between the radio device and the wireless relay device (or between the radio devices themselves) to a frequency used for the second sea area. For example, the radio device receiving the communication configuration information can change its current first communication mode to the second communication mode. The second communication mode can represent a mode with a different communication configuration than the first communication mode. The first communication mode can represent the communication mode used in the sea area before the vessel's sea area change (e.g., territorial sea 420); the second communication mode can represent the communication mode used in the sea area the vessel has entered (e.g., nearshore sea area 410). For example, the second communication mode may include one or more of the following: a wireless communication frequency band used in a second sea area (e.g., nearshore sea area 410), a frequency used for wireless communication, and a signal strength for wireless communication. The control device may cause one or more radio devices to adjust the signal strength for communication of the radio devices to the signal strength for wireless communication contained in the received communication configuration information in response to communication configuration information received from a wireless relay device.

[0076] According to one embodiment, a vessel located at a first position 401 in territorial waters 420 can enter a second position 402 in nearshore waters 410. In this case, a first communication mode can represent the communication mode when the vessel's maritime position is in territorial waters 420; a second communication mode can represent the communication mode when the vessel's maritime position is in nearshore waters 410, communicating with communication facilities at a port on land. Nearshore waters 410 can represent an area closer to land than territorial waters 420. The control device can cause one or more radio devices to change the frequency used for communication between radio devices to a frequency used for wireless communication with port communication facilities (e.g., 156.650 MHz) in response to communication configuration information received from a wireless relay device.

[0077] In one embodiment, a vessel located at a first position 401 in the territorial sea 420 may enter a third position 403 in the high seas 430. In this case, a first communication mode may represent the communication mode when the vessel's maritime position is in the territorial sea 420; a second communication mode may represent the communication mode when the vessel's maritime position is in the high seas 430. A control device may cause one or more radio devices to change the frequency used for communication between radio devices to a frequency used for wireless communication in the high seas 430 (e.g., 15 MHz) in response to communication configuration information received from a wireless relay device.

[0078] In one embodiment, a vessel located at a third position 403 in the high seas 430 can enter a first position 401 in the territorial sea 420. In this case, a first communication mode can represent the communication mode when the vessel's maritime position is in the high seas 430; a second communication mode can represent the communication mode when the vessel's maritime position is in the territorial sea 420. A control device can cause one or more radio devices to change the frequency used for communication between radio devices to a frequency used for wireless communication in the territorial sea 420 (e.g., 4 MHz) in response to communication configuration information received from a wireless relay device.

[0079] Figure 5 This is a flowchart illustrating a control method for controlling the communication mode of a radio device according to an embodiment. The control method for controlling the communication mode of a radio device can be implemented by a control device (e.g., [missing information]). Figure 1 The control device 110) is used for execution.

[0080] Referring to Figure 5, in step 510, the control device can acquire information about the ship (e.g., Figure 2 The control device can obtain the location information of the vessel (100). The control device can obtain the location information of the vessel at sea through GPS sensors or base station-based networks.

[0081] In step 530, the control device can identify communication configuration information based on location information. When the control device senses the ship's maritime position as it moves from the first sea area to the second sea area based on the ship's location information, it can identify the communication configuration information corresponding to the second communication mode. The first communication mode can represent a mode with a different communication configuration than the second communication mode. The communication mode corresponding to the first sea area can indicate the first communication mode; the communication mode corresponding to the second sea area can indicate the second communication mode. The communication configuration information can include one or more of the following: the wireless communication frequency band used in the second sea area, the frequency used for wireless communication, and the signal strength of the wireless communication.

[0082] In step 550, the control device may send communication configuration information to the wireless relay device. For example, the control device may send communication configuration information corresponding to the second communication mode to the wireless relay device, so that the wireless relay device may send the communication configuration information corresponding to the second communication mode to one or more radio devices. The wireless relay device may perform metal-body communication using the ship's metal hull as a medium to transmit signals.

[0083] In one embodiment, when the vessel's maritime position is sensed to have moved from a first sea area to a second sea area, the control device can generate an alarm request signal to enable a radio device to provide an alert informing of the change in sea area. The control device can then send the alarm request signal to a wireless relay device, which in turn forwards the alarm request signal to one or more radio devices.

[0084] In step 570, the control device may use communication configuration information to adjust the communication environment of the radio devices. The communication environment may include the frequency band, frequency, and wireless communication strength for the wireless communication of the radio devices. The control device may cause one or more radio devices to change the frequency used for communication between the radio devices to a frequency used for wireless communication in the sea area the ship has entered, in response to the communication configuration information received from the wireless relay device. For example, the radio devices may change the frequency used for communication between (or between) the radio devices and the wireless relay device to a frequency used for wireless communication in a second sea area the ship has entered, in response to the communication configuration information received from the wireless relay device. The control device may also cause one or more radio devices to adjust the strength of the communication signal used by the radio devices to the signal strength of the wireless communication contained in the received communication configuration information, in response to the communication configuration information received from the wireless relay device.

[0085] In one embodiment, the first communication mode may represent the communication mode when the ship's maritime position is within territorial waters; the second communication mode may represent the communication mode for communicating with port communication facilities on land when the ship's maritime position is in nearshore waters closer to land than territorial waters. The control device may cause one or more radio devices to change the frequency used for communication between radio devices to a frequency used for wireless communication with port communication facilities in response to communication configuration information received from a wireless relay device.

[0086] In one embodiment, the first communication mode may represent the communication mode when the vessel's position at sea is within territorial waters; the second communication mode may represent the communication mode when the vessel's position at sea is on the high seas. The control device may cause one or more radio devices to change the frequency used for communication between radio devices to a frequency used for wireless communication on the high seas in response to communication configuration information received from a wireless relay device.

[0087] In one embodiment, the first communication mode may represent the communication mode when the ship's position at sea is on the high seas; the second communication mode may represent the communication mode when the ship's position at sea is in territorial waters. The control device may cause one or more radio devices to change the frequency used for communication between radio devices to a frequency used for wireless communication in territorial waters in response to communication configuration information received from a wireless relay device.

When, based on the ship's position information, it senses that the ship's maritime position has moved from a first sea area corresponding to a first communication mode to a second sea area corresponding to a second communication mode, the control device 600 can identify communication configuration information corresponding to the second communication mode and send this communication configuration information to a wireless relay device.

The control device 600 may cause one or more radio devices to change the frequency used for communication between radio devices to a frequency used for wireless communication with port communication facilities in response to communication configuration information received from a wireless relay device.

[0097] According to one embodiment, a first communication mode can represent the communication mode when the ship's position at sea is within territorial waters; a second communication mode can represent the communication mode when the ship's position at sea is on the high seas.

[0100] The control device 600 can cause one or more radio devices to adjust the signal strength for communication of the radio devices to the signal strength of wireless communication contained in the received communication configuration information in response to communication configuration information received from a wireless relay device.

[0101] When the control device senses that the ship's position at sea has moved from the first sea area to the second sea area, it can generate an alarm request signal to enable the radio device to provide an alarm informing the change of sea area, and can send the alarm request signal to a wireless relay device so that the wireless relay device can send the alarm request signal to one or more radio devices.
