Description

发射信号的控制方法、网络设备、终端及存储介质Control method, network equipment, terminal and storage medium for transmitting signal 技术领域Technical field
本申请涉及通信领域，具体而言，涉及一种发射信号的控制方法、网络设备、终端及存储介质。This application relates to the field of communications, and in particular, to a method for controlling transmitted signals, network equipment, terminals, and storage media.
背景技术Background technique
众所周知，在飞行器(例如，飞机)上是很难进行打电话或上网等的通信业务，因为空中没有像在地面上的网络覆盖。通常情况下如要进行通信则会基于卫星通信网络，但通信费用非常高，且容量很小，难以普及。因此基于地面的基站的飞机通信则成为一个潜在的方向。As we all know, it is difficult to make communication services such as making phone calls or surfing the Internet on an aircraft (for example, an airplane), because there is no network coverage in the air like on the ground. Under normal circumstances, communication is based on satellite communication networks, but the communication cost is very high, and the capacity is small, making it difficult to popularize. Therefore, aircraft communication based on ground-based base stations has become a potential direction.
在相关技术中，提出了一种飞行器基于地面基站的通信的方法，在该方法中，在飞行器路线上通过不同的基站来实现连续覆盖，保证飞行器可以始终有网络连接服务。但这种方式也有它的问题。一般飞行器的飞行高度都在1万米以上的距离，而要在经济可承受的范围内保证连续覆盖，则单个基站的覆盖区域要足够大才行，也即地面站间距离会很大，这导致基站的发射功率会很高，进而引起耗电严重。In the related art, a communication method for aircraft based on ground base stations is proposed. In this method, different base stations are used to achieve continuous coverage on the aircraft route to ensure that the aircraft can always have network connection services. But this method also has its problems. Generally, the flying height of aircraft is more than 10,000 meters. To ensure continuous coverage within an affordable range, the coverage area of a single base station must be large enough, that is, the distance between ground stations will be large. As a result, the transmission power of the base station will be very high, which will cause serious power consumption.
针对上述的问题，目前尚未提出有效的解决方案。In view of the above-mentioned problems, no effective solutions have yet been proposed.

基于上述说明，本申请实施例提出了一种发射信号的控制方法。图2为本申请实施例提供的发射信号的控制方法一的示意性流程图，如图2所示，该方法包括：Based on the foregoing description, an embodiment of the present application proposes a method for controlling a transmitted signal.

In addition, the service signal transmitted by the first base station may be a service signal transmitted by the first base station to serve the aircraft. The first base station serves the aircraft by transmitting signals, that is, the first base station serves the terminals on the aircraft by transmitting signals.
通过上述步骤，在飞行器基于地面的基站进行通信时，基于飞行器的飞行信息控制第一基站发射服务信号，使得第一基站并不需要一直都采用最大发射功率进行发射，因此，有效地降低了飞行器基于地面的基站进行通信时，基站的耗电。Through the above steps, when the aircraft communicates with the ground-based base station, the first base station is controlled to transmit service signals based on the flight information of the aircraft, so that the first base station does not need to always use the maximum transmission power for transmission, thus effectively reducing the aircraft When a ground-based base station communicates, the power consumption of the base station.
作为一种可选的实施例，本发明实施例所指的飞行器可以是在大气层内飞行的器械，例如，可以是飞机，飞艇，滑翔机，直升机，无人机和气球等。本发明实施例所指的飞行器基于地面的基站进行通信，可以是指飞行器中的终端通过地面的基站进行通信。As an optional embodiment, the aircraft referred to in the embodiments of the present invention may be equipment flying in the atmosphere, for example, it may be an airplane, an airship, a glider, a helicopter, an unmanned aerial vehicle, and a balloon. The aircraft mentioned in the embodiment of the present invention communicates based on the base station on the ground, which may mean that the terminal in the aircraft communicates through the base station on the ground.
可选地，本发明实施例所提供的发射信号的控制方法一的执行主体可以是网络设备，该网络设备可以包括核心网中任何能够实现上述方法功能的设备，较佳地，该网络设备可以是基站。Optionally, the execution subject of the first method of transmitting signal control provided by the embodiment of the present invention may be a network device, and the network device may include any device in the core network that can implement the functions of the above method. Preferably, the network device may It is a base station.
可选地，该飞行器的飞行信息用于描述飞行器的飞行状态的，在本发明实施例中， 主要用于确定飞行器与基站之间的相对位置，用于基站发射的信号能够覆盖飞行器飞行的区域，而且，飞行器的飞行信息越准确地描述也与基站的相对位置时，可以更为准确地控制基站的发射功率，从而能够为基站节省更多功耗。Optionally, the flight information of the aircraft is used to describe the flight status of the aircraft. In the embodiment of the present invention, it is mainly used to determine the relative position between the aircraft and the base station, and the signal transmitted by the base station can cover the area where the aircraft is flying. And, the more accurately the flight information of the aircraft describes the relative position of the base station, the more accurate the base station's transmit power can be controlled, which can save more power consumption for the base station.
作为一种可选的实施例，在本发明实施例中，飞行信息可以包括多种，例如，可以包括以下至少之一：飞行路线、地理位置、高度、速度、方向。飞行器的飞行路线即飞行器进行飞行时所经过的位置的总和，从该飞行路线可以看出飞行器所经过的位置，能够较好地确定用于为飞行器提供服务的基站。飞行器需要经过的地理位置可以是一个具体命名地城市，当然也可能是一个以基站所在地命名的地名等。飞行器飞行的高度可以是一般意义上的与地平线的高度，为更为准确地控制基站的发射功率，该高度可以是以基站所在水平高度为准的高度。通过飞行器飞行的速度和方向，可以有效地获知飞行器进入地面上的基站所覆盖范围的小区内的开始时间，飞经整个小区的时间，以及飞离小区的结束时间，从而能够更准确地控制基站的发射功率。As an optional embodiment, in the embodiment of the present invention, the flight information may include multiple types, for example, may include at least one of the following: flight route, geographic location, altitude, speed, and direction. The flight path of the aircraft is the sum of the positions passed by the aircraft during flight. From the flight path, the position passed by the aircraft can be seen, and the base station used to provide services for the aircraft can be better determined. The geographic location that the aircraft needs to pass through can be a specifically named city, or of course, a place name named after the location of the base station. The flying height of the aircraft may be the height above the horizon in a general sense. In order to more accurately control the transmission power of the base station, the height may be based on the level where the base station is located. Through the flying speed and direction of the aircraft, you can effectively know the start time of the aircraft entering the cell covered by the base station on the ground, the time of flying through the entire cell, and the end time of flying away from the cell, so as to control the base station more accurately The transmit power.
在本发明实施例中，在根据飞行信息控制第一基站发射服务信号时，可以采用多种方式。例如，可以基于下面两种方式控制第一基站发射服务信号。第一种方式，通过飞行器移动的位置是否在第一基站的小区覆盖范围内，来控制第一基站发射服务信号以及控制第一基站停止发射服务信号；第二种方式，飞行器在第一基站覆盖的小区内移动的过程中，控制第一基站发射服务信号。In the embodiment of the present invention, when controlling the first base station to transmit the service signal according to the flight information, multiple methods can be used. For example, the first base station can be controlled to transmit service signals based on the following two methods. The first method controls the first base station to transmit service signals and controls the first base station to stop transmitting service signals based on whether the moving position of the aircraft is within the cell coverage of the first base station; in the second method, the aircraft is covered by the first base station In the process of moving within the cell, control the first base station to transmit service signals.
对于第一种方式，根据飞行信息控制第一基站发射服务信号时，可以根据飞行信息判断飞行器是否移动到第一基站的小区覆盖范围内；在判断结果为飞行器移动到第一基站的小区覆盖范围内时，控制第一基站发射服务信号。需要说明的是，飞行器移动到第一基站的小区覆盖范围内，可以是飞行器开始进入第一基站的小区覆盖范围，也可以是飞行器已经在第一基站的小区范围内有一段时间了。较佳地，可以是飞行器开始进入第一基站覆盖的小区的时间点上，控制第一基站开始发射服务信号，避免飞行器不在第一基站的小区覆盖范围内，第一基站也发射服务信号，造成发射功率的浪费。当然，如果飞行器不是恰好移动到小区，例如，飞行器已经在小区内飞行了一段时间后，只要检测到飞行器处于第一基站的小区覆盖范围内，就控制第一基站开始发射服务信号。针对这种情况，虽然不能以最省电的方式服务飞行器上的终端，但相对于第一基站一直处于开启状态而言，在一定程度上也能有效节省第一基站的功耗。For the first method, when controlling the first base station to transmit service signals according to the flight information, it can be judged according to the flight information whether the aircraft has moved within the cell coverage area of the first base station; the result of the judgment is that the aircraft has moved to the cell coverage area of the first base station When in, control the first base station to transmit service signals. It should be noted that when the aircraft moves within the cell coverage of the first base station, the aircraft may start to enter the cell coverage of the first base station, or the aircraft has been within the cell coverage of the first base station for a period of time. Preferably, at the time when the aircraft starts to enter the cell covered by the first base station, the first base station is controlled to start transmitting service signals to prevent the aircraft from being out of the cell coverage of the first base station and the first base station also transmits service signals, causing Waste of transmit power. Of course, if the aircraft does not happen to move to the cell, for example, after the aircraft has been flying in the cell for a period of time, as long as it is detected that the aircraft is within the cell coverage of the first base station, the first base station is controlled to start transmitting service signals. In view of this situation, although the terminal on the aircraft cannot be served in the most power-saving manner, compared to the first base station being always on, the power consumption of the first base station can be effectively saved to a certain extent.
另外，在上述第一种方式中，在控制第一基站发射服务信号之后，还可以包括：判断飞行器是否移动出第一基站的小区覆盖范围；在判断结果为飞行器移动出第一基站的小区覆盖范围的情况下，控制第一基站停止发射服务信号。较佳地，可以在一确定飞行器移动出第一基站的小区覆盖范围的时间点上，即确定飞行器刚飞离第一基站的小区覆盖范围时，立即控制第一基站停止发射服务信号，使得第一基站的功耗能够 有效地降低。针对另一种情况，即飞行器移动出第一基站的小区覆盖范围的时间点上，没有控制第一基站停止发射服务信号，只要过一段时间确定了飞行器移动出了第一基站的小区覆盖范围，这时控制第一基站停止发射服务信号，相对于第一基站一直以最大功率进行发射而言，也能够有效地降低基站的功耗。In addition, in the above-mentioned first method, after controlling the first base station to transmit the service signal, it may further include: determining whether the aircraft has moved out of the cell coverage area of the first base station; In the case of range, control the first base station to stop transmitting service signals. Preferably, at a point in time when it is determined that the aircraft has moved out of the cell coverage area of the first base station, that is, when it is determined that the aircraft has just flew out of the cell coverage area of the first base station, the first base station can be immediately controlled to stop transmitting service signals, so that the first base station The power consumption of a base station can be effectively reduced. For another situation, that is, when the aircraft moves out of the cell coverage area of the first base station, the first base station is not controlled to stop transmitting service signals, as long as it is determined that the aircraft has moved out of the cell coverage area of the first base station after a period of time, At this time, controlling the first base station to stop transmitting service signals can also effectively reduce the power consumption of the base station compared to the first base station always transmitting at the maximum power.
需要说明的是，通过上述第一方式，来控制第一基站发射服务信号以及控制第一基站停止发射服务信号仅仅为“根据飞行信息控制第一基站发射服务信号”的一种举例。在具体实施时，还可以采用其它方式来实现。It should be noted that controlling the first base station to transmit service signals and controlling the first base station to stop transmitting service signals through the above-mentioned first method is only an example of “controlling the first base station to transmit service signals according to flight information”. In specific implementation, it can also be implemented in other ways.
比如，飞行器还未移动到第一基站的小区覆盖范围内时，即在距离第一基站的小区覆盖范围还有一段距离的情况下，就控制第一基站发射服务信号，这样虽然会浪费一些第一基站的功耗，但相对于第一基站一直处于开启状态而言，还是能够节省第一基站的功耗的。浪费的功耗可以通过上述距离的长短来控制，控制一个合适的距离，不仅能够节省功耗，而且还具有无间断地服务飞行器的好处。For example, when the aircraft has not moved within the cell coverage of the first base station, that is, when there is still some distance from the cell coverage of the first base station, it controls the first base station to transmit service signals. The power consumption of a base station can still save the power consumption of the first base station compared to the first base station being always on. The wasted power consumption can be controlled by the length of the above-mentioned distance. Controlling an appropriate distance not only saves power consumption, but also has the benefit of uninterrupted service to the aircraft.
又比如，飞行器在未移动出第一基站的小区覆盖范围时，就控制第一基站停止发射服务信号，也能够有效降低第一基站的功耗。采用这种方式降低基站功耗时，可以让第一基站的小区覆盖范围与第二基站的小区覆盖范围有覆盖重叠区，这样飞行器在该覆盖重叠区在未飞离第一基站的小区覆盖范围时，第二基站也能够为该飞行器提供信号覆盖。For another example, when the aircraft has not moved out of the cell coverage of the first base station, it controls the first base station to stop transmitting service signals, which can also effectively reduce the power consumption of the first base station. When using this method to reduce the power consumption of the base station, the cell coverage of the first base station and the cell coverage of the second base station can have a coverage overlap area, so that the aircraft does not fly away from the cell coverage area of the first base station in the coverage overlap area. When the time, the second base station can also provide signal coverage for the aircraft.
需要说明的是，对于飞行器还未移动到第一基站的小区覆盖范围内就控制第一基站发射服务信号的情况，上述提前控制第一基站发射服务信号时，提前发射服务信号的时间长度，不仅可以依据飞行器距离第一基站的小区覆盖范围的距离来确定，还可以依据第一基站的小区覆盖范围与第二基站的小区覆盖范围的覆盖重叠区的大小来确定。对于上述提前控制第一基站停止发射服务信号，提前停止发射服务信号的时间长度，不仅可以依据第一基站的小区覆盖范围与第二基站的小区覆盖范围的覆盖重叠区的大小来确定，还可以依据飞行器飞离第一基站的小区覆盖范围还剩下的距离来确定。It should be noted that, for the case where the aircraft is controlled to transmit service signals by the first base station before it has moved within the cell coverage of the first base station, the above mentioned advance control of the first base station to transmit service signals, the advancement of the length of time for transmitting the service signals, not only It may be determined according to the distance between the aircraft and the cell coverage of the first base station, and may also be determined according to the size of the coverage overlap area of the cell coverage of the first base station and the cell coverage of the second base station. Regarding the foregoing control of the first base station to stop transmitting service signals in advance, and the length of time for stopping transmitting service signals in advance, not only can be determined according to the size of the coverage overlap area between the cell coverage of the first base station and the cell coverage of the second base station, but also It is determined according to the remaining distance of the aircraft flying away from the cell coverage area of the first base station.
作为一种可选的实施例，为实现第一基站与第二基站能够无缝地为飞行器上的终端服务，在控制第一基站停止发射服务信号之前，还包括：向第二基站发送激活信息，其中，激活信息用于激活第二基站向飞行器发射服务信号，第二基站为飞行器移动方向上与第一基站相邻的基站。即在飞行器要由第一基站的小区覆盖范围移动到第二基站的小区覆盖时，需要实现由第一基站所覆盖的小区与第二基站所覆盖的小区之间的切换。因此，在飞行器移动出第一基站的小区覆盖范围时，向第二基站发送激活信息，用于激活第二基站来服务飞行器上的终端，从而实现服务的连续性。As an optional embodiment, in order to realize that the first base station and the second base station can seamlessly serve the terminals on the aircraft, before controlling the first base station to stop transmitting service signals, the method further includes: sending activation information to the second base station , Where the activation information is used to activate the second base station to transmit service signals to the aircraft, and the second base station is a base station adjacent to the first base station in the moving direction of the aircraft. That is, when the aircraft is to be moved from the cell coverage of the first base station to the cell coverage of the second base station, it is necessary to implement handover between the cell covered by the first base station and the cell covered by the second base station. Therefore, when the aircraft moves out of the cell coverage area of the first base station, the activation information is sent to the second base station for activating the second base station to serve the terminals on the aircraft, thereby achieving service continuity.
对于第二种方式，飞行器在第一基站的小区覆盖范围内移动的过程中，控制第一 基站发射服务信号。对于这种控制方式，也可以分为两个方面：一是从第一基站主动控制的方面来控制第一基站发射服务信号；另一个是从飞行器的反馈的功率控制信息来控制第一基站发射服务信号。下面分别说明。For the second method, the aircraft controls the first base station to transmit service signals while moving within the cell coverage of the first base station. This control method can also be divided into two aspects: one is to control the first base station to transmit service signals from the aspect of the first base station's active control; the other is to control the first base station to transmit from the power control information fed back from the aircraft. Service signal. Described below separately.
从第一基站主动控制的方面来控制第一基站发射服务信号：Control the first base station to transmit service signals from the aspect of active control by the first base station:
从第一基站主动控制的方面来控制第一基站发射服务信号可以采用多种方式。例如，可以采用以下两种方式：第一种，控制第一基站发射多个窄波束向飞行器发射服务信号，其中，多个窄波束的指向依据飞行信息确定。多个窄波束的发射时间分别依据飞行信息确定，比如，通过在不同的时间内发送不同的窄波束来实现对飞行器飞行路线的覆盖。第二种，控制第一基站通过窄波束的方式向飞行器发射服务信号，其中，窄波束的指向基于飞行信息进行调整。即控制第一基站通过窄波束追踪飞行器的方式完成对飞行器飞行路线的覆盖。比如，通过控制窄波束的发送方向以及强度，通过追踪飞行器的方式来实现对飞行器飞行路线的覆盖。There are many ways to control the first base station to transmit service signals from the aspect of active control of the first base station. For example, the following two methods can be used: First, the first base station is controlled to transmit multiple narrow beams to transmit service signals to the aircraft, where the directions of the multiple narrow beams are determined according to flight information. The transmission time of the multiple narrow beams is determined according to the flight information, for example, the coverage of the flight path of the aircraft is achieved by sending different narrow beams at different times. The second type is to control the first base station to transmit service signals to the aircraft through a narrow beam, where the direction of the narrow beam is adjusted based on the flight information. That is, the first base station is controlled to complete the coverage of the flight path of the aircraft by means of narrow beam tracking of the aircraft. For example, by controlling the transmission direction and intensity of the narrow beam, and by tracking the aircraft, the coverage of the flight path of the aircraft can be achieved.
由于飞行器在移动到第一基站的小区覆盖范围后，飞行器也不是同时处于所覆盖区域的任何地方，因此，对于飞行器目前不在的部分区域是可以不发射服务信号的。因此，为进一步地降低第一基站的功耗，可以仅对飞行器当时飞行的区域发射服务信号，具体地，可以通过窄波束的方式来发射服务信号。例如，对于上述第一种，在第一时间段内采用波束1来为飞行器上的终端服务，在第二时间段内采用波束2来为飞行器上的终端服务，在第三时间段内采用波束3来为飞行器上的终端服务等。又例如，对于上述第二种，采用窄波束在第一方向上采用第一信号强度来为飞行器上的终端服务，在第二方向上采用第二信号强度来为飞行器上的终端服务，在第三方向上采用第三信号强度来为飞行器上的终端服务，这样一直追踪飞行器，从而完成对飞行器飞行路线的覆盖。After the aircraft moves to the cell coverage area of the first base station, the aircraft is not located anywhere in the covered area at the same time. Therefore, it is not necessary to transmit service signals for some areas where the aircraft is not currently located. Therefore, in order to further reduce the power consumption of the first base station, the service signal may be transmitted only to the area where the aircraft is flying at the time, specifically, the service signal may be transmitted in a narrow beam manner. For example, for the first type mentioned above, beam 1 is used to serve the terminals on the aircraft in the first time period, beam 2 is used to serve the terminals on the aircraft in the second time period, and beams are used in the third time period. 3 to serve the terminal on the aircraft, etc. For another example, for the above-mentioned second type, the narrow beam is used in the first direction to use the first signal strength to serve the terminal on the aircraft, and the second signal strength is used in the second direction to serve the terminal on the aircraft. The third signal strength is used in the three directions to serve the terminal on the aircraft, so that the aircraft is always tracked to complete the coverage of the flight path of the aircraft.
从飞行器的反馈的功率控制信息来控制第一基站发射服务信号：The power control information fed back from the aircraft controls the first base station to transmit service signals:
控制第一基站发射服务信号，还可以包括：获取飞行器发送的功率控制信息；基于功率控制信息调整第一基站发射服务信号的发射功率。其中，该功率控制信息可以是用于对第一基站发射服务信号的发射功率进行控制的信息，来自于飞行器反馈的信息，例如，可以是来自于飞行器接收到信号强度测量值，可以是来自于飞行器指示信息，其中，该指示信息用于指示对第一基站发射服务信号的发射功率进行调整等。Controlling the first base station to transmit the service signal may also include: acquiring power control information sent by the aircraft; and adjusting the transmission power of the first base station to transmit the service signal based on the power control information. Wherein, the power control information may be information used to control the transmission power of the service signal transmitted by the first base station, and may come from information fed back from the aircraft. For example, it may be from a signal strength measurement value received by the aircraft, or from Aircraft indication information, where the indication information is used to indicate adjustment of the transmission power of the service signal transmitted by the first base station, etc.
基于上述功率控制信息的不同，基于功率控制信息调整第一基站的发射功率也可以不同，下面举例说明。Based on the above-mentioned difference in power control information, the adjustment of the transmit power of the first base station based on the power control information may also be different, as described below with an example.
例如，在功率控制信息包括飞行器接收到的信号强度测量值的情况下，根据信号强度测量值调整第一基站发射服务信号的发射功率。比如，当飞行器接收到的服务信 号强度测量值较大时，表明第一基站发射服务信号较好地服务飞行器上的终端，因此，在能够满足飞行器上的终端的需求的情况下，为避免第一基站的功耗的浪费，可以适当地降低第一基站的发射功率。而当飞行器接收到的服务信号测量值较小时，表明第一基站发送的服务信号不能满足飞行器上的终端的需求，因此，需要适当地提高第一基站发射服务信号的发射功率。For example, in a case where the power control information includes the signal strength measurement value received by the aircraft, the transmission power of the service signal transmitted by the first base station is adjusted according to the signal strength measurement value. For example, when the service signal strength measurement value received by the aircraft is large, it indicates that the service signal transmitted by the first base station can better serve the terminal on the aircraft. The waste of power consumption of a base station can appropriately reduce the transmission power of the first base station. When the measured value of the service signal received by the aircraft is small, it indicates that the service signal sent by the first base station cannot meet the requirements of the terminal on the aircraft. Therefore, it is necessary to appropriately increase the transmission power of the service signal transmitted by the first base station.
基于上述飞行器接收到的信号强度测量值的强弱仅仅是一种相对概念，为使得信号强度测量值的强弱有一个明确地界定，可以明确一个信号强度阈值。通过该信号强度阈值由飞行器给第一基站一个明确的指示，第一基站即可以根据这个明确地指示，调整第一基站发射服务信号的发射功率。具体地，根据信号强度测量值调整第一基站发射服务信号的发射功率可以采用如下方式：在飞行器接收到的信号强度测量值大于或等于信号强度阈值的情况下，降低第一基站发射服务信号的发射功率；和/或，在飞行器接收到的信号强度测量值小于信号强度阈值的情况下，提高第一基站发射服务信号的发射功率。相对于上述直接依据飞行器接收的信号强度测量值来调整第一基站发射服务信号的发射功率，采用信号强度阈值明确指示信号强度测量值强弱的方式，可以有效地减少第一基站的处理，能够有效地提高调整第一基站发射服务信号的发射功率的效率。Based on the strength of the signal strength measurement value received by the above-mentioned aircraft, it is only a relative concept. In order to make the strength of the signal strength measurement value have a clear definition, a signal strength threshold can be clarified. Through the signal strength threshold, the aircraft gives a clear indication to the first base station, and the first base station can adjust the transmission power of the service signal transmitted by the first base station according to this clear indication. Specifically, adjusting the transmission power of the service signal transmitted by the first base station according to the measured signal strength may adopt the following manner: when the measured signal strength received by the aircraft is greater than or equal to the signal strength threshold, reduce the transmission power of the service signal transmitted by the first base station. Transmit power; and/or, in the case that the signal strength measurement value received by the aircraft is less than the signal strength threshold, increase the transmit power of the service signal transmitted by the first base station. Compared with the above-mentioned adjustment of the transmission power of the service signal transmitted by the first base station directly according to the signal strength measurement value received by the aircraft, the signal strength threshold value is used to clearly indicate the strength of the signal strength measurement value, which can effectively reduce the processing of the first base station. Effectively improve the efficiency of adjusting the transmission power of the service signal transmitted by the first base station.
又例如，基于功率控制信息调整第一基站发射服务信号的发射功率可以包括：在功率控制信息包括指示信息的情况下，基于指示信息调整第一基站发射服务信号的发射功率，其中，该指示信息用于指示对第一基站发射服务信号的发射功率进行调整。在该方法中，飞行器可以直接依据飞行器上的终端的通信需求，直接向第一基站发送调整该第一基站发射服务信号的发射功率的指示信息。需要说明的是，这里所指的通信需求可以是，飞行器上的终端对数据的需求，也可以是飞行器上的终端对信号强度的需求等。采用依据需求直接向第一基站发送指示信息的方式，使得第一基站调整发射功率更为直接，有效。For another example, adjusting the transmission power of the service signal transmitted by the first base station based on the power control information may include: when the power control information includes indication information, adjusting the transmission power of the service signal transmitted by the first base station based on the indication information, where the indication information It is used to instruct to adjust the transmission power of the service signal transmitted by the first base station. In this method, the aircraft can directly send the instruction information for adjusting the transmission power of the service signal transmitted by the first base station to the first base station according to the communication requirements of the terminals on the aircraft. It should be noted that the communication requirement referred to here may be the requirement of the terminal on the aircraft for data, or the requirement of the terminal on the aircraft for signal strength. The method of directly sending the instruction information to the first base station according to the demand makes it more direct and effective for the first base station to adjust the transmission power.
不管采用上述哪种方式，根据飞行信息控制第一基站发射服务信号，获取飞行器的飞行信息时，均可以采用多种方式，例如，均可以采用以下获取方式至少之一：通过交换节点获取飞行器的飞行信息，其中，交换节点与飞行器飞行路线上的所有基站进行通信；从第三基站接收飞行器的飞行信息，其中，第三基站为为飞行器移动方向上飞行器移动出的基站。当有一个交换节点用于对所有基站进行管理时，由于该交换节点会与所有的基站实时交换信息，基于交换节点与多个基站的交互，就能够确定飞行器的飞行信息。因此，可以从该交换节点获取飞行器的飞行信息。另外，由于相互相邻的基站之间也可以进行交互，基于该第一基站可以从与第一基站相邻的第三基站接收飞行器的飞行信息。采用直接从相邻基站获取飞行器的飞行信息的方式，不仅具备快速的特点，而且由于不需要中间设备转发，因此真实准确。Regardless of the above method, when controlling the first base station to transmit service signals according to flight information and acquiring flight information of the aircraft, multiple methods can be used. For example, at least one of the following acquisition methods can be used: Flight information, where the switching node communicates with all base stations on the flight path of the aircraft; and receives the flight information of the aircraft from a third base station, where the third base station is a base station that the aircraft moves in the moving direction of the aircraft. When a switching node is used to manage all base stations, since the switching node exchanges information with all base stations in real time, the flight information of the aircraft can be determined based on the interaction between the switching node and multiple base stations. Therefore, the flight information of the aircraft can be obtained from the switching node. In addition, since base stations adjacent to each other can also interact with each other, the first base station can receive flight information of the aircraft from a third base station adjacent to the first base station. The method of obtaining the flight information of the aircraft directly from the neighboring base station is not only fast, but also true and accurate because it does not require intermediate equipment for forwarding.
本申请实施例还提出了一种发射功率控制。图3为本申请实施例提供的发射信号的控制方法二的示意性流程图，如图3所示，该方法包括：The embodiment of the application also proposes a transmission power control. FIG. 3 is a schematic flowchart of a second method for controlling a transmitted signal according to an embodiment of the application. As shown in FIG. 3, the method includes:
S302，确定飞行器的飞行信息；S302: Determine the flight information of the aircraft;
S304，将飞行信息发送给网络设备，其中，该飞行信息用于网络设备依据飞行信息控制第一基站发射服务信号。其中，该第一基站可以是为飞行器服务的地面基站中的任一基站。S304: Send the flight information to the network device, where the flight information is used by the network device to control the first base station to transmit the service signal according to the flight information. Wherein, the first base station may be any base station among ground base stations serving the aircraft.
通过上述步骤，将飞行器的飞行信息发送给网络设备，用于网络设备根据飞行器的飞行信息控制第一基站发射服务信号，使得第一基站并不需要一直都采用最大发射功率进行发射服务信号，因此，有效地降低了飞行器基于地面的基站进行通信时，基站的耗电。Through the above steps, the flight information of the aircraft is sent to the network device for the network device to control the first base station to transmit the service signal according to the flight information of the aircraft, so that the first base station does not need to always use the maximum transmission power to transmit the service signal. , Effectively reducing the power consumption of the base station when the aircraft communicates with the ground-based base station.
需要说明的是，该方法中的执行主体可以是飞行器上的终端，终端的类型也可以多种，例如，可以是智能终端，比如，可以是一些智能手机、智能穿戴设备等智能终端。It should be noted that the execution subject in this method may be a terminal on the aircraft, and the type of terminal may also be multiple, for example, it may be a smart terminal, for example, it may be some smart terminals such as smart phones and smart wearable devices.
作为一种可选的实施例，控制第一基站发射服务信号的发射功率包括：若飞行器移动到第一基站的小区覆盖范围，控制第一基站发射服务信号；若飞行器移动出第一基站的小区覆盖范围，控制第一基站停止发射服务信号。另外，需要说明的是，在控制第一基站发射服务信号后，还可以控制第一基站通过窄波束的方式进行发射服务信号，从而达到进一步降低第一基站功耗的效果。例如，控制第一基站发射多个窄波束向飞行器发射服务信号，其中，多个窄波束的指向依据飞行信息确定，该多个窄波束的发射时间分别依据飞行信息确定；又例如，还可以控制第一基站通过窄波束的方式向飞行器发射服务信号，其中，窄波束的指向基于飞行信息进行调整。As an optional embodiment, controlling the transmission power of the service signal transmitted by the first base station includes: if the aircraft moves to the cell coverage area of the first base station, controlling the first base station to transmit the service signal; if the aircraft moves out of the cell of the first base station Coverage range, controlling the first base station to stop transmitting service signals. In addition, it should be noted that after controlling the first base station to transmit the service signal, the first base station may also be controlled to transmit the service signal in a narrow beam manner, thereby achieving the effect of further reducing the power consumption of the first base station. For example, the first base station is controlled to transmit multiple narrow beams to transmit service signals to the aircraft, wherein the directions of the multiple narrow beams are determined according to flight information, and the transmission time of the multiple narrow beams is determined according to the flight information; for example, it can also be controlled The first base station transmits a service signal to the aircraft through a narrow beam, where the direction of the narrow beam is adjusted based on the flight information.
作为一种可选的实施例，在将飞行信息发送给网络设备之后，还可以向网络设备发送功率控制信息，其中，功率控制信息用于网络设备调整第一基站的发射功率。其中，该功率控制信息可以包括多种，例如，可以包括以下至少之一：飞行器接收到的信号强度测量值，指示信息，其中，指示信息用于网络设备(例如，第一基站)对所第一基站的发射功率进行调整。通过由飞行器(例如，可以是飞行器上的终端)直接发送上述功率控制信息的方式，来实现对第一基站的发射功率的调整，使得对第一基站的发射功率的调整更为直接，有效，并且能够有效降低第一基站的功耗。As an optional embodiment, after the flight information is sent to the network device, power control information may also be sent to the network device, where the power control information is used by the network device to adjust the transmit power of the first base station. The power control information may include multiple types, for example, it may include at least one of the following: a signal strength measurement value received by the aircraft, and indication information, where the indication information is used by the network device (for example, the first base station) The transmit power of a base station is adjusted. The transmission power of the first base station is adjusted by the aircraft (for example, a terminal on the aircraft) directly sending the above-mentioned power control information, so that the adjustment of the transmission power of the first base station is more direct and effective. And can effectively reduce the power consumption of the first base station.
结合上述实施例及优选实施例，下面以飞机为例，对本发明优选实施方式进行说明。With reference to the above-mentioned embodiments and preferred embodiments, the following takes an airplane as an example to describe the preferred embodiments of the present invention.
在本优选实施方式中，提供了一种在基站与飞机通信的场景中，降低基站耗电的方法。该方法包括：基站根据飞机经过的时间及路线信息，通过分时控制基站发射服 务信号、分波束覆盖飞行器飞行路线的方法，辅助基站管理服务信号的发射时间；或通过飞机向基站发送功率控制信息(该功率控制信息可以包括多种，例如，可以是飞机接收到的信号强度测量值、指示信息(比如，反馈基站功率控制指令等))，辅助基站管理服务信号的发射功率。In this preferred embodiment, a method for reducing the power consumption of the base station in a scenario where the base station communicates with an aircraft is provided. The method includes: according to the time and route information of the aircraft, the base station controls the base station to transmit service signals through time sharing, and the sub-beams cover the flight path of the aircraft, assisting the base station to manage the transmission time of the service signals; or transmitting power control information to the base station through the aircraft (The power control information may include multiple types, for example, it may be a signal strength measurement value received by the aircraft and indication information (for example, feedback of base station power control instructions, etc.)), which assists the base station to manage the transmission power of the service signal.
优选实施方式1：分时控制基站发射服务信号Preferred Embodiment 1: Time-sharing control base station to transmit service signal
针对相关技术中，用于跟飞机进行通信的基站需要具有很高的发射功率来达到足够大的空中小区覆盖半径，这类基站如一直处于开启状态则耗电严重。为解决该问题，在本发明实施例中，提供了一种从分时开启基站的角度进行考虑，从而减少基站的耗电。需要说明的是，本申请所指的飞机与基站进行的通信，其实是飞机上的终端与基站进行的通信，实现飞机上的终端的通信功能。本申请所指的基站即是相对于空中的飞机而言的地面基站，即在本申请中基站与地面基站为同一对象。In the related art, the base station used to communicate with the aircraft needs to have a high transmit power to reach a sufficiently large air cell coverage radius. Such a base station consumes a lot of power if it is always turned on. To solve this problem, in the embodiment of the present invention, a method is provided from the perspective of turning on the base station in a time-sharing manner, thereby reducing the power consumption of the base station. It should be noted that the communication between the airplane and the base station referred to in this application is actually the communication between the terminal on the airplane and the base station, which realizes the communication function of the terminal on the airplane. The base station referred to in this application refers to the ground base station relative to the aircraft in the air, that is, the base station and the ground base station are the same object in this application.
飞机与基站的通信有个不同于普通陆地通信的特点在于：用户数量少，且可以通过预定方式得到该用户接入网络的时间、地点等信息。进而可以只在有飞机经过的时候开启基站进行网络覆盖。The communication between the aircraft and the base station is different from ordinary terrestrial communication in that the number of users is small, and information such as the time and location of the user's access to the network can be obtained through a predetermined method. Furthermore, the base station can be turned on for network coverage only when an airplane passes by.
图4是根据本发明实施例所提供的控制基站发射服务信号的示意图，如图4所示，飞机的飞行路线、地理位置、高度、速度、方向等信息会经过飞机信息交换节点实时告知基站。当飞机即将经过小区1所在覆盖范围时，基站1开启并完成对小区1所在区域的覆盖。当飞机即将离开小区1时，小区2激活并进行小区切换，此后小区1关闭。Fig. 4 is a schematic diagram of controlling the base station to transmit service signals according to an embodiment of the present invention. As shown in Fig. 4, the aircraft’s flight route, geographic location, altitude, speed, direction and other information will be notified to the base station in real time via the aircraft information exchange node. When the aircraft is about to pass the coverage area of cell 1, base station 1 turns on and completes the coverage of the area where cell 1 is located. When the plane is about to leave cell 1, cell 2 is activated and cell handover is performed, after which cell 1 is closed.
飞机信息的交换节点可以跟所有基站直接连接并进行实时信息的交互，也可以仅跟部分基站连接并通过激活基站将信息告知下一个要开始发射服务信号的基站。The aircraft information exchange node can be directly connected to all base stations and exchange real-time information, or it can only be connected to some base stations and inform the next base station that will start transmitting service signals by activating the base station.
另外，为了进一步降低基站的耗电，提升覆盖，基站可通过窄波束实时追踪飞机的方式来降低发射功率。飞机的地理位置信息、高度、指向、速度等信息都会告知基站，则基站可以通过一个或多个相对较窄的波束分时来完成飞机路线的覆盖。图5是根据本发明实施例所提供的基站基于窄波束完成飞机飞行路线覆盖的示意图，如图5所示，在时刻1开启波束1，在时刻2开启波束2，时刻3开启波束3，完成对飞机飞行路线的覆盖。也可以通过动态调整波束指向来追踪飞机，完成在飞机整个飞行路线的覆盖及双向通信。In addition, in order to further reduce the power consumption of the base station and increase coverage, the base station can reduce the transmit power by tracking the aircraft in real time through a narrow beam. The aircraft's geographic location information, altitude, direction, speed and other information will be notified to the base station, and the base station can use one or more relatively narrow beam time-sharing to complete the coverage of the aircraft route. Fig. 5 is a schematic diagram of a base station according to an embodiment of the present invention completing aircraft flight route coverage based on narrow beams. As shown in Fig. 5, beam 1 is turned on at time 1, beam 2 is turned on at time 2, and beam 3 is turned on at time 3. Coverage of the flight path of the aircraft. The aircraft can also be tracked by dynamically adjusting the beam direction to complete the coverage and two-way communication of the aircraft's entire flight path.
优选实施方式2：基于飞机反馈的功率控制信息，控制基站发射服务信号的发射功率Preferred Embodiment 2: Based on the power control information fed back by the aircraft, control the transmission power of the service signal transmitted by the base station
通常情况下，在飞机进入某一区域(例如，可以是上述所指的基站覆盖的小区，也可以是上述窄波束覆盖的飞机飞行路线)时，为了保证飞机所经过区域的覆盖效果， 基站会按照最大功率进行发射。而功率越大则耗电越大，通过降低基站的发射功率来降低耗电也是一个可行途径。Generally, when an aircraft enters a certain area (for example, it can be a cell covered by the aforementioned base station, or it can be an aircraft flight path covered by the aforementioned narrow beam), in order to ensure the coverage of the area passed by the aircraft, the base station will Transmit according to the maximum power. The greater the power, the greater the power consumption. It is also a feasible way to reduce the power consumption by reducing the transmission power of the base station.
在飞机初始进入小区(例如，上述的小区1)所在区域时，基站为了与飞机建立初始链路需要以高的功率发射服务信号。在初始链路建立后，飞机反馈基站功率控制信息，辅助基站进行发射功率的调整。该基站功率控制信息可以为以下几种：When the aircraft initially enters the area where the cell (for example, the aforementioned cell 1) is located, the base station needs to transmit a service signal with high power in order to establish an initial link with the aircraft. After the initial link is established, the aircraft feeds back the power control information of the base station to assist the base station in adjusting the transmit power. The base station power control information can be of the following types:
(1)飞机反馈测量到的基站信号强度(1) The aircraft feeds back the measured signal strength of the base station
在飞机经过小区1所在区域时，飞机测量接收信号强度，并将信号强度测量值反馈给基站。基站通过该信号强度测量值便可以判断当前飞机所经过路线的覆盖情况，并进一步调整发射服务信号的发射功率，以避免不必要的发射功率。When the aircraft passes through the area where cell 1 is located, the aircraft measures the received signal strength and feeds back the measured signal strength to the base station. The base station can determine the coverage of the current route of the aircraft through the signal strength measurement value, and further adjust the transmission power of the transmitted service signal to avoid unnecessary transmission power.
(2)飞机基于门限反馈基站信号强度(2) The aircraft feeds back the signal strength of the base station based on the threshold
与上面类似，但此时当飞机测量到的信号强度持续大于或等于一定门限时，飞机反馈指示信息1给基站；当飞机测量到的信号强度持续小于一定门限时，飞机反馈指示信息2给基站。基站收到指示信息1后可降低基站发射服务信号的发射功率，收到指示信息2后可提高基站发射服务信号的发射功率。Similar to the above, but at this time, when the signal strength measured by the aircraft continues to be greater than or equal to a certain threshold, the aircraft feeds back instruction information 1 to the base station; when the signal strength measured by the aircraft continues to be less than a certain threshold, the aircraft feeds back instruction information 2 to the base station . The base station can reduce the transmission power of the service signal transmitted by the base station after receiving the instruction information 1, and can increase the transmission power of the service signal transmitted by the base station after receiving the instruction information 2.
(3)飞机直接反馈基站发射功率控制指令(也是一种指示信息)(3) The aircraft directly feeds back the base station transmit power control command (also a kind of indication information)
与上面反馈测量到的信号强度或基于门限反馈信号强度不同，此处飞机可以直接基于需求反馈基站发射功率控制指令。(注：在一般的陆地通信***中基站为了保证最大覆盖其一般采用的是最大功率发射，而且考虑到小区内的众多用户所处位置不同，基站一般保持发射功率不变)。Unlike the above feedback of measured signal strength or threshold-based feedback signal strength, the aircraft here can directly feed back base station transmit power control commands based on demand. (Note: In the general terrestrial communication system, the base station generally uses the maximum power transmission in order to ensure the maximum coverage, and considering the different locations of many users in the cell, the base station generally keeps the transmission power unchanged).
图6是根据本发明实施例所提供的由飞机向地面基站发送基站发射功率控制指令的示意图，如图6所示，飞机直接向地面基站发送基站发射功率控制指令，即飞机直接向地面基站发送功率控制指令来控制基站发射服务信号的的发射功率。具体地，飞机对基站的发射功率控制指令可以基于需求来判断，比如，当接收信号过低时，或飞机上对数据速率需求大时等，直接向基站发送增加基站发射服务信号的发射功率的请求指令。基站收到该请求指令后，如有功率余量则增加发射功率。反之，当基站收到降低发射功率请求时，可降低发射功率。Figure 6 is a schematic diagram of an aircraft sending a base station transmission power control command to a ground base station according to an embodiment of the present invention. As shown in Figure 6, the aircraft directly sends a base station transmission power control command to the ground base station, that is, the aircraft directly sends a base station transmission power control command to the ground base station. The power control command controls the transmission power of the base station to transmit service signals. Specifically, the aircraft's transmit power control command to the base station can be determined based on demand. For example, when the received signal is too low, or when the aircraft has a large data rate demand, it can directly send to the base station to increase the transmit power of the base station's service signal. Request instructions. After receiving the request instruction, the base station increases the transmission power if there is power margin. Conversely, when the base station receives a request to reduce the transmission power, it can reduce the transmission power.
通过上述优选实施方式，可减少基站的开启时间或降低发射功率，最终达到降低基站耗电的目的。Through the above-mentioned preferred implementation manners, the turn-on time of the base station or the transmission power can be reduced, and finally the purpose of reducing the power consumption of the base station is achieved.
