The network-side device can also be referred to as an access network device or a radio access network device. It can be a transmission reception point (TRP) carried by a satellite, or an evolved NodeB (eNB or eNodeB) in an LTE system carried by a satellite, or a radio controller in a cloud radio access network (CRAN) scenario carried by a satellite, or a gNB in an NR system carried by a satellite, or an urban base station, a micro base station, a pico base station, a femto base station, etc. carried by a satellite.

[0154] Other terms:

[0155] Terms 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 sequence. Those skilled in the art can understand that terms such as "first", "second", etc. do not limit the quantity and execution order, and terms such as "first", "second", etc. do not necessarily mean different.

[0156] Words such as "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in this application should not be construed as more preferred or more advantageous than other embodiments or design solutions. Rather, using words such as "exemplary" or "for example" aims to present relevant concepts in a specific manner.

[0157] "At least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships can exist. 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 in 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.

[0158] Public warning systems, also known as public warning systems (PWS), include earthquake and tsunami warning systems (ETWS) and commercial mobile alert services (CMAS). Public warning systems do not provide emergency rescue services for ships in distress.

[0159] In the field of international mobile communications, based on the different mobile communication services, international mobile communications are usually divided into emergency communications, security communications, routine communications, service communications, and distress communications.

[0160] Emergency communications can be used for rapid rescue and coordination when mobile vehicles encounter serious disruptions to traffic safety or order.

[0161] 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.

[0162] 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 vessel, routine communication can be used for business contacts between the vessel and shore-based management agencies, port authorities, cargo owners, or agents.

[0163] 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.

[0164] Distress communication is used for rescue or coordination when a mobile vehicle encounters serious danger. When the mobile vehicle is a vessel, distress communication can also be called vessel distress communication.

[0165] Optionally, vessel distress communication may include radio communication or satellite communication.

[0166] 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.

[0167] 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.

[0168] In radio and satellite communications, distressed vessels send distress information to the search and rescue coordination center. The search and rescue coordination center responds to the distress information, selects rescue vessels that meet preset conditions and have the relevant capabilities, and sends rescue information to the rescue vessels to notify them to rescue the distressed vessels.

[0169] Currently, when the distance between a distressed vessel and the search and rescue coordination center exceeds a certain range, the center may not be able to receive the distress information in a timely manner. Furthermore, the center needs to select rescue vessels that meet preset conditions and have the relevant capabilities, which results in a significant delay in the transmission of rescue information. In addition, the rescue information may fail to be transmitted, leading to poor timeliness in rescuing distressed vessels.

[0170] In view of this, this application provides a communication method in which a new communication process is designed. The second device can send abnormal information to a network-side device that is not on the ground, and the network-side device can send the abnormal information of the second device to the first device. This achieves the purpose of using the network-side device as a forwarding node for abnormal information, without having to go through the search and rescue coordination center to select a first device that meets preset conditions and has relevant capabilities. This can reduce the transmission delay of abnormal information and improve the timeliness of rescue of the second device.

[0176] S201. The second device sends an anomaly message to the network-side device. Correspondingly, the network-side device receives the anomaly message from the second device.

[0177] In one implementation, the second device may be a terminal with maritime communication capabilities.

[0178] In one implementation, the network-side device is the network device corresponding to the serving cell where the second device is located. The serving cell may also be referred to as a maritime communication satellite cell.

[0179] In one implementation, the abnormal information may be referred to as shipwreck information or distress information, etc.

[0180] The abnormal information is used to indicate that there is an abnormality in the second device.

[0181] In the embodiments of this application, "abnormality" can be understood as being in danger or in distress.

The second information indicates the abnormal information of the second device, thereby realizing the purpose of using the network-side device as a forwarding node for abnormal information. It is not necessary to select a first device that meets the preset conditions and has relevant capabilities through the search and rescue coordination center, which reduces the transmission delay of abnormal information and improves the timeliness of rescue for the second device.

[0198] Furthermore, in this embodiment, indicating the abnormal information of the second device through the second information can reduce the overhead of system resources. Further, when the network-side device is a satellite, in the communication method adopted in this embodiment, the information transmission path is "second device—satellite—first device," and the wireless communication undergoes relevant processing by the search and rescue coordination center, improving the timeliness of information transmission and enabling efficient distress rescue.

[0220] S302. The network-side device sends DCI to the first device via PDCCH. Correspondingly, the first device listens to PDCCH to receive DCI via PDCCH.

[0221] In one implementation, the PDCCH is a PDCCH scrambled with a first Radio Network Temporary Identifier (RNTI).

[0222] The first RNTI is used to identify the second information, which includes anomaly information.

[0223] In one implementation, one first device corresponds to one first RNTI, or multiple first devices correspond to one first RNTI.

[0224] In one implementation, when a first device corresponds to a first RNTI, the network-side device can configure a corresponding first RNTI for each first device, and the first device corresponding to the configured first RNTI has the ability to descramble the PDCCH scrambled by the first RNTI. When the network-side device sends DCI through the PDCCH scrambled by the first RNTI, only the first device with the ability to descramble the first RNTI can obtain the DCI sent through the PDCCH scrambled by the first RNTI.

[0225] In one implementation, when multiple first devices correspond to a first RNTI, the network-side device configures a first RNTI for the multiple first devices. When the network-side device transmits DCI via a PDCCH scrambled with the first RNTI, all multiple first devices with the capability to descramble the first RNTI can obtain the DCI transmitted via the PDCCH scrambled with the first RNTI.

[0226] In one implementation, the first RNTI can be a temporary identifier for a maritime dedicated wireless network.

[0227] The abbreviation for a maritime dedicated wireless network temporary identifier is, for example, M-RNTI. The full name of M-RNTI is, for example, Maritime Radio Network Temporary Identifier.

[0228] DCI is used to indicate whether there is a device malfunction.

[0229] In one implementation, the DCI can be a marine-specific DCI.

[0230] In one implementation, the DCI includes first indication information. The first indication information is used to indicate whether there is a device malfunction or to indicate whether there is second information.

[0231] The first instruction information can also be called rescue instruction information, rescue message instruction, or search and rescue message instruction, etc.

[0232] The following combination Figure 1 Provide a description of at least the information included in the DCI.

[0233] Table 1

[0234]

[0235] In one implementation, the first indication information is, for example, 1, used to indicate that there is a device malfunction or that there is second information; the first indication information is, for example, 0, used to indicate that there is no device malfunction or that there is no second information.

[0236] In one implementation, the first indication information is, for example, 0, used to indicate that there is a device malfunction or that there is second information; the first indication information is, for example, 1, used to indicate that there is no device malfunction or that there is no second information.

[0237] S303. When the DCI is used to indicate a device malfunction, the network-side device sends a second message to the first device. Correspondingly, the first device receives the second message.

[0238] The second information is used to indicate abnormal information of the second device.

[0239] exist Figure 3 In the communication method provided in the embodiment, the second device sends abnormal information to the network-side device, and the network-side device sends DCI to the first device. When the DCI indicates that there is a device abnormality, the network-side device sends second information to the first device. The second information indicates the abnormal information of the second device, thereby achieving the purpose of using the network-side device as a forwarding node for abnormal information. It is not necessary to select a first device that meets the preset conditions and has relevant capabilities through the search and rescue coordination center, which reduces the transmission delay of abnormal information and improves the timeliness of rescue for the second device.

[0240] The following combination Figure 4 Taking a short message as an example, the communication method provided in the embodiments of this application will be described. Figure 4 This is the third flowchart illustrating the communication method provided in this application. Figure 4 As shown, the method includes:

[0241] S401. The second device sends an anomaly message to the network-side device. Correspondingly, the network-side device receives the anomaly message from the second device.

[0242] S402. The network-side device sends a short message to the first device via the PDCCH. Correspondingly, the first device listens to the PDCCH to receive short messages via the PDCCH.

[0243] In one implementation, the first device listens to the PDCCH on a paging occasion (PO) or a paging frame (PF) to receive short messages via the PDCCH.

[0244] In one implementation, the PDCCH can be a PDCCH scrambled by a second RNTI.

[0245] The second RNTI is used to identify the second information, which includes abnormal information.

[0246] In one implementation, one first device corresponds to one second RNTI, or multiple first devices correspond to one second RNTI.

[0247] In one implementation, when a first device corresponds to a second RNTI, the network-side device can configure a corresponding second RNTI for each first device, and the first device corresponding to the configured second RNTI has the ability to descramble the PDCCH scrambled by the second RNTI. When the network-side device sends a short message through the PDCCH scrambled by the second RNTI, only the first device with the ability to descramble the second RNTI can obtain the short message sent through the PDCCH scrambled by the second RNTI.

[0248] In one implementation, when multiple first devices correspond to a single second RNTI, the network-side device configures a second RNTI for each of the multiple first devices. When the network-side device sends a short message via a PDCCH scrambled with the second RNTI, all the multiple first devices capable of descrambling the second RNTI can obtain the short message sent via the PDCCH scrambled with the second RNTI.

[0249] In one implementation, the second RNTI is, for example, a paging radio network temporary identifier (P-RNTI).

[0250] Among them, SMS messages are used to indicate whether there is a device malfunction.

[0251] In one implementation, the SMS message includes a first indication message, which is used to indicate whether there is a device malfunction.

[0252] In one implementation, the first indication information may occupy one bit in the short message.

[0253] In one implementation, the first indication information is, for example, 1, used to indicate that there is a device malfunction or that there is second information; the first indication information is, for example, 0, used to indicate that there is no device malfunction or that there is no second information.

[0254] In one implementation, the first indication information may be bit 5, bit 6, bit 7, or bit 8 in the short message.

[0255] In one implementation, bits other than bits 5, 6, 7, and 8 in the short message can also be reused to represent the first indication information.

[0256] In one implementation, bit 2 in the short message can be reused to represent the first indication information.

[0257] When bit 2 is used to represent the first indication information, the first indication information can also be understood as a notification of the existence of the second information. The notification of the second information can also be understood as a rescue notification.

[0258] In one implementation, the first indication information (e.g., bit 2) is used to indicate one or more of the following: a rescue notification, an Earthquake and Tsunami Warning System (ETWS) primary notification, an Earthquake and Tsunami Warning System (ETWS) secondary notification, or a Commercial Mobile Alert System (CAMS) notification.

[0259] The following explanation will focus on the role of each bit in short messages in two related technologies.

[0260] Table 2

[0261]

[0262] When the first indication information is bit 5 in the short message, the function of each bit in the short message is shown in Table 3 below.

[0263] Table 3

[0264]

[0265]

[0266] When the first indication information is bit 2 in the short message, the meaning of bit 2 can be expanded. The function of each bit in the corresponding short message is shown in Table 4 below.

[0267] Table 4

[0268]

[0269] S403. When a short message is used to indicate a device malfunction, the network-side device sends a second message to the first device. The first device then receives the second message.

[0270] The second information is used to indicate abnormal information of the second device.

[0271] exist Figure 4 In the communication method provided in the embodiment, the second device sends abnormal information to the network-side device, and the network-side device sends a short message to the first device. When the short message indicates that there is a device abnormality, the network-side device sends a second message to the first device. The second message indicates the abnormal information of the second device, thereby realizing the purpose of using the network-side device as a forwarding node for abnormal information. It is not necessary to select a first device that meets the preset conditions and has relevant capabilities through the search and rescue coordination center, which reduces the transmission delay of abnormal information and improves the timeliness of rescue for the second device.

[0272] In one implementation, the network-side device can send the second information to the first device using time-frequency domain resources of the second information. Correspondingly, the first device can receive the second information using time-frequency domain resources of the second information.

[0273] In one implementation, the first information can also be used to indicate a first time-frequency domain resource.

[0274] In one implementation, the time-frequency domain resource of the second information may or may not be the first time-frequency domain resource.

[0275] When the time-frequency domain resource of the second information is not the first time-frequency domain resource, the time-frequency domain resource of the second information is determined according to the first time-frequency domain resource and the time-frequency domain resource indicated by the System Information Blocks (SIB).

The first device also receives the SIB.

When the first information indicates a device malfunction, the network-side device sends the second information to the first device on the time-frequency domain resources of the second information. Correspondingly, the first device receives the second information on the time-frequency domain resources of the second information.

[0285] The second information is used to indicate abnormal information of the second device.

[0318] Among them, SMS messages are used to indicate whether there is a device malfunction.

[0319] S703. When a short message indicates that a device malfunction exists, the network-side device sends an SIB to the first device.

[0320] In some embodiments, when the first device receives a short message indicating a device malfunction, it can determine whether it has maritime communication capabilities. If it does have maritime communication capabilities, it receives the SIB.

[0339] The first beam coverage area includes the second device and N first devices. Before the adjustment, the network-side device could communicate with the second device and the N first devices, while M other devices were not covered by the network-side device's beam, therefore the network-side device could not communicate with the M other devices.

[0340] The coverage area of ​​the second beam is the coverage area of ​​the adjusted beam.

[0341] The second beam coverage area includes the second device, N first devices, and M other devices.
