[0043] The following is a detailed description of a signal coverage control method and apparatus provided in the embodiments of this application, with reference to the accompanying drawings.

[0044] The terms "first" and "second," etc., in the specification and drawings of this application are used to distinguish different objects, rather than to describe a specific order of objects. For example, "first edge network device" and "second edge network device," etc., are used to distinguish different edge network devices, rather than to describe a specific order of edge network devices.

[0045] Furthermore, the terms “comprising” and “having”, and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such processes, methods, products, or apparatus.

[0046] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0047] The term "and / or" as used in this application includes using either one of two methods or using both methods simultaneously.

[0048] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0049] As described in the background art, due to the large area affected by natural disasters and the limited communication capabilities of emergency communication vehicles, some areas in these disaster zones lack signal coverage, resulting in communication failures for terminals within those areas. Therefore, this application provides a signal coverage range control method and apparatus. In this embodiment, when the central network device is not located in the target area or does not provide full signal coverage, signal coverage in the edge area can be achieved using an edge network device. When the edge network device is located at the edge of the signal coverage area of ​​the central network device, the central network device can send a coverage function activation instruction to the edge network device, enabling the edge network device to activate its signal coverage function. This effectively achieves signal coverage in the edge area, thereby quickly and efficiently achieving full signal coverage of the target area.

[0050] The signal coverage range control method and apparatus provided in this application can be applied to signal coverage range control systems, such as... Figure 1 As shown, the signal coverage control system includes a terminal 101, a central network device 102, and an edge network device 103. Typically, in practical applications, the connection between these devices or service functions can be wireless. To easily and intuitively illustrate the connection relationships between the devices, Figure 1 Solid lines are used to represent the meaning.

[0051] The terminal 101 is used to receive the target signal coverage area sent by the central network device 102, and is also used to display the target signal coverage area sent by the central network device 102, receive the target multimedia resources sent by the central network device 102, and display the target multimedia resources sent by the central network device 102.

[0052] The central network device 102 is used to send a coverage function activation instruction to the edge network device 103, receive a coverage function activation response sent by the edge network device 103, send the target signal coverage range to the terminal 101, receive the target multimedia resources sent by the edge network device 103, send the target multimedia resources to the terminal 101, and send the target prompt information to the edge network device 103. The central network device 102 is also used to enable the edge network device 103 to access the network.

[0053] Edge network device 103 is used to receive a coverage function activation instruction sent by central network device 102, and is also used to activate the signal coverage function of edge network device 103, send a coverage function activation response to central network device 102, send target multimedia resources to central network device 102, receive target prompt information sent by central network device 102, and issue target prompt information. Edge network device 103 is also used to enable terminal 101 to access the network.

[0054] For example, the central network device 102 and the edge network device 103 can be base stations, evolved node base stations (eNBs), next-generation node base stations (gNBs), new radio eNBs, macro base stations, micro base stations, high-frequency base stations or transmission and reception points (TRPs), non-3GPP access networks (such as WiFi) and / or non-3GPP interworking functions (N3IWFs), etc.

[0055] For example, with Figure 1 Taking a commonly used base station as an example, the hardware structure of the central network device 102 provided in this application embodiment is described. Figure 2As shown, the base station provided in this application embodiment may include part 20 and part 21. Part 20 is mainly used for transmitting and receiving radio frequency signals and converting radio frequency signals to baseband signals; part 21 is mainly used for baseband processing and controlling the base station. Part 20 can generally be referred to as a transceiver unit, transceiver, transceiver circuit, or transceiver, etc. Part 21 is usually the control center of the base station and can generally be referred to as a processing unit.

[0056] The 20-part transceiver unit, also known as a transceiver or transceiver, includes an antenna and a radio frequency (RF) unit, or only an RF unit or a portion thereof. The RF unit is primarily used for RF processing. Optionally, the devices in the 20-part unit that implement the receiving function can be considered as receiving units, and the devices that implement the transmitting function can be considered as transmitting units; that is, the 20-part unit includes both receiving and transmitting units. The receiving unit can also be called a receiver, receiver circuit, or receiving device, and the transmitting unit can be called a transmitter, transmitter, or transmitting circuit.

[0057] Part 21 may include one or more single boards or chips. Each single board or chip may include one or more processors and one or more memories. The processor is used to read and execute programs in the memory to implement baseband processing functions and control the base station. If multiple single boards exist, they can be interconnected to increase processing power. As an optional implementation, multiple single boards may share one or more processors, or multiple single boards may share one or more memories. The memory and processor may be integrated or independently configured. In some embodiments, parts 20 and 21 may be integrated or independently configured. In addition, all functions in part 21 may be integrated into one chip, or some functions may be integrated into one chip while other functions may be integrated into one or more other chips. This application embodiment does not limit this.

[0058] The signal coverage range control method and apparatus provided in this application are applied to the scenario of signal coverage range control. When the distance between the central network device and the edge network device is greater than or equal to the distance threshold, the central network device can send a coverage function activation instruction to the edge network device. At this time, the edge network device activates the signal coverage function of the edge network device to achieve regional signal coverage.

[0059] In combination with the above Figure 1 The signal coverage control system shown below is described in its entirety from the perspective of the interaction between the central network device and the edge network device. The method for controlling the signal coverage provided in this application is illustrated to explain the process by which the central network device controls the edge network device to achieve signal coverage.

[0060] like Figure 3 As shown, the signal coverage control method provided in this application embodiment may include S101-S106.

[0061] S101. When the signal coverage area of ​​the central network device is outside the target area and / or the signal coverage area of ​​the central network device is smaller than the target area, the central network device determines the distance between the central network device and each of the at least one edge network device.

[0062] It should be understood that if the signal coverage area of ​​the central network device is outside the target area and / or the signal coverage area of ​​the central network device is smaller than the target area, it means that the signal coverage area of ​​the central network device is not within the target area or cannot fully cover the target area. In this case, the central network device can determine the distance between the central network device and each of the at least one edge network device.

[0063] For example, the target area could be an area that has suffered a natural disaster.

[0064] In one implementation of this application, the central network device may consist of an indoor baseband processing unit (BBU) and a remote radio unit (RRU). Specifically, the RRU may be mounted on a drone and connected to the BBU via an optical-electric composite cable, so as to achieve signal coverage in severely affected areas.

[0065] S102. When the distance between the central network device and the first edge network device is greater than or equal to the distance threshold, the central network device sends a coverage function activation instruction to the first edge network device.

[0066] The coverage function activation indicator is used to instruct the first edge network device to enable the signal coverage function, and the first edge network device is one of the at least one edge network device.

[0067] It should be understood that if the distance between the central network device and the first edge network device is greater than or equal to the distance threshold, it indicates that the first edge network device is located in the edge area of ​​the signal coverage range of the central network device. In this case, the central network device can send a coverage function activation instruction to the first edge network device.

[0068] In one implementation of this application, the first edge network node can be a drone equipped with a fourth-generation mobile communication technology (long term evolution, LTE) base station module.

[0069] S103. The edge network device receives the coverage function activation instruction sent by the central network device.

[0070] The coverage function activation instruction is used to instruct the edge network device to enable the signal coverage function. The coverage function activation instruction is sent by the central network device to the edge network device when the distance between the central network device and the edge network device is greater than or equal to a distance threshold.

[0071] It is understood that the edge network device is the aforementioned first edge network device.

[0072] S104. The edge network device enables the signal coverage function of the edge network device and determines the coverage area of ​​the edge network device based on the coverage range of the edge network device.

[0073] Based on the above embodiments, it should be understood that both the edge network device and the central network device are equipped with a relay module and a relay antenna. The central network device can enable signal coverage for the edge network device based on the relay module and the relay antenna.

[0074] It is understood that the central network device provides signals to the edge network device based on the relay modules and relay antennas included in the central network node, and the relay modules and relay antennas included in the edge network device are used to receive the signals provided by the central network device.

[0075] S105. The edge network device sends a coverage function activation response to the central network device.

[0076] The coverage function activation response includes the signal coverage area of ​​the edge network device, and the coverage function activation response is used to notify the central network device that the signal coverage function of the edge network device has been successfully activated.

[0077] Understandably, once the signal coverage function of the edge network is successfully activated, terminals within the area covered by the edge network signal can perform communication processes such as data transmission.

[0078] S106. The central network device receives the coverage function activation response sent by the first edge network device.

[0079] The coverage function response includes the signal coverage area of ​​the first edge network device. The coverage function activation response is used to notify the central network device that the signal coverage function of the first edge network device has been successfully activated. The signal coverage areas of the first edge network device and the signal coverage areas of the central network device are used to achieve signal coverage for the target area.

[0080] In one implementation of this application, after the central network device receives the coverage function activation response sent by the first edge network device, it can accurately determine the areas within the target area that can be covered by the signal, and it can determine the areas within the target area that are not yet covered by the signal, so that other edge network devices can provide signal coverage to the areas within the target area that are not yet covered by the signal.

[0081] The technical solution provided by the above embodiments can bring at least the following beneficial effects: As can be seen from S101-S106: when the signal coverage area of ​​the central network device is outside the target area and / or the signal coverage area of ​​the central network device is smaller than the target area, the central network device can determine the distance between the central network device and each of the at least one edge network device. Then, when the distance between the central network device and the first edge network device is greater than or equal to the distance threshold, the central network device sends a coverage function activation instruction to the first edge network device. The coverage function activation instruction is used to instruct the first edge network device to activate the signal coverage function. At this time, after receiving the coverage function activation instruction sent by the central network device, the edge network device can activate the signal coverage function of the edge network device based on the coverage function activation instruction, and determine the coverage area of ​​the edge network device based on the coverage range of the edge network device. Then, the edge network device sends a coverage function activation response to the central network device. The central network device receives the coverage function activation response sent by the first edge network device. The coverage function activation response includes the signal coverage area of ​​the first edge network device. At this time, the central network device can obtain the signal coverage area of ​​the edge device. In this embodiment of the application, when the central network device is not located in the target area or the central network device does not provide full signal coverage to the target area, signal coverage in the edge area can be achieved based on the edge network device. When the edge network device is located at the edge of the signal coverage area of ​​the central network device, the central network device can send a coverage function activation instruction to the edge network device so that the edge network device can activate the signal coverage function, thereby effectively achieving signal coverage in the edge area, and thus effectively and quickly achieving full signal coverage of the target area.

[0082] Combination Figure 3 ,like Figure 4 As shown, the signal coverage control method provided in this application embodiment also includes S107-S108.

[0083] S107. The central network device determines the target signal coverage area by summing the signal coverage areas of the central network device and the respective signal coverage areas of the M edge network devices.

[0084] Wherein, the M edge network devices are network devices among the at least one edge network device that have enabled signal coverage function, and M is an integer greater than or equal to 1.

[0085] Based on the above embodiments, it should be understood that the signal coverage area of ​​the central network device and the signal coverage areas of each of the M edge network devices constitute the area within the target region where signal coverage is achieved. At this time, the electronic device determines the target signal coverage area as the sum of the signal coverage area of ​​the central network device and the signal coverage areas of each of the M edge network devices. The target signal coverage area can represent all signal coverage areas within the target region.

[0086] S108. The central network device sends the target signal coverage area to the target terminal so that the target terminal can display the target signal coverage area.

[0087] Optionally, the target terminal can be the terminal of the rescue personnel in the target area. In this case, the central network device sends the target signal coverage area to the target terminal, which can make the target terminal display the target signal coverage area, thereby enabling the rescue personnel to conveniently and quickly determine the signal coverage area in the target area, facilitating the rescue personnel to carry out personnel search and rescue.

[0088] In this embodiment, the central network device can determine the sum of its signal coverage area and the signal coverage areas of each of the M edge network devices as all signal coverage areas in the target area. At this time, the central network device sends all signal coverage areas in the target area to the target terminal, which can quickly and effectively enable the target terminal to display all signal coverage areas in the target area.

[0089] Combination Figure 3 ,like Figure 5 As shown, the signal coverage control method provided in this application embodiment further includes S109.

[0090] S109. When a target object exists in the signal coverage area of ​​the edge network device, the edge network device sends the target multimedia resources to the central network device, so that the central network device sends the target multimedia resources to the target terminal.

[0091] The target multimedia resource refers to the multimedia resource corresponding to the target object.

[0092] It should be understood that if the target object exists in the signal coverage area of ​​the edge network device, it means that there are people in need of rescue in the signal coverage area of ​​the edge network device. At this time, the edge network device sends the target multimedia resources to the central network device, which in turn sends the target multimedia resources to the target terminal. This can effectively send the target multimedia resources to the target terminal, so that rescuers can quickly locate the target object and carry out rescue.

[0093] Combination Figure 5 ,like Figure 6 As shown, the signal coverage control method provided in this application embodiment also includes S110-S111.

[0094] S110, The central network device receives the target multimedia resources sent by the first edge network device.

[0095] The target multimedia resource is the multimedia resource corresponding to the target object, and the target multimedia resource is sent by the first edge network device to the central network device when the target object exists in the signal coverage area of ​​the first edge network device.
