Technical Field

Background

The international union report shows that the population of nearly 2/3 in the world is not networked at present, and is mainly distributed in remote areas with low population density. Network coverage for these areas by terrestrial base stations can be very costly. The use of aerial platforms (balloons, airships, drones) to provide wide coverage networks for remote areas is a new approach.

At present, Google balloon plan and facial makeup network facebook unmanned aerial vehicle plan are all performing corresponding platform development and communication test, and a high-altitude platform communication network enters the rapid development stage of the industry.

Compared with a ground wireless communication network, the high-altitude platform has the following advantages: strong coverage, high power efficiency and high spectrum efficiency.

Because the high-altitude nodes are in the process of continuous movement, the link capacity among the nodes and even the network topology can change at any time, and the ground area covered by each high-altitude node also changes dynamically. How to quickly detect whether a high-altitude node fails or not, no reference scheme exists at present.

The second ground station may be one or more. Likewise, the second high-altitude platform and the third high-altitude platform may also be one or more.

The connection status information may include a connection status of the second ground station with the first high-altitude platform, a connection status of the second high-altitude platform with the first high-altitude platform, and a connection status of the third high-altitude platform with the first high-altitude platform.

By knowing whether other network equipment is connected with the first high-altitude platform or not, whether the first high-altitude platform breaks down or not can be quickly detected.

In one possible implementation, the at least one network device includes: a second ground station adjacent to the first ground station, a second high-altitude platform connected with the second ground station through a wireless backhaul link, and a third high-altitude platform connected with the first ground station through a wireless backhaul link; the first ground station determines whether the first high-altitude platform fails according to the connection state information, and the method comprises the following steps: the first ground station learns that the first high-altitude platform is not connected with the second ground station, the second high-altitude platform and the third high-altitude platform according to the connection state information; the first ground station determines that the first high altitude platform is malfunctioning.

If the connection state information received by the first ground station includes that at least one network device is connected with the first high-altitude platform, the first ground station may consider that the first high-altitude platform is normal and has no fault.

If the first network device is a second high-altitude platform, the second high-altitude platform sends the state request received by the second ground station to the first ground station through the second ground station, and the second high-altitude platform determines whether the second high-altitude platform is connected with the first high-altitude platform.

It is also possible that a certain high-altitude platform establishes a connection with a second high-altitude platform or a third high-altitude platform, but does not establish a connection with the first ground station and an adjacent second ground station, and then the first ground station may also acquire status information whether it establishes a connection with the first high-altitude platform through the second high-altitude platform or the third high-altitude platform.

The High altitude platform communication system in the embodiment of the invention is used for communication by using a High Altitude Platform (HAP) to replace a satellite as a base station, and the height of the platform is about 17 km-22 km from the ground. A helium-filled airship, a balloon or an airplane can be used as a platform for arranging the repeater station, and if the height of the platform is 20km, the communication area with the ground covering radius of about 500km can be realized.

The high-altitude platform communication system mainly comprises high-altitude platform and ground facility communication, high-altitude platform and satellite network communication and high-altitude platform communication. The ground facilities include various terminal devices, ground wireless networks, telecommunication backbone networks, the internet and the like. The high-altitude platform can be directly communicated with the terminal equipment and can also be connected with other networks through a ground gateway, so that the inter-network communication is conveniently realized and the existing service is supported; the satellite network is an important component of a data communication network, and particularly in the fields of military affairs, scientific research and the like, the satellite communication has an irreplaceable function. The communication between the high-altitude platform and the satellite network can improve the measurement and control precision and level of the satellite while expanding the communication application of the stratosphere. The information can be directly transmitted through the platform, or the information can be transmitted to the satellite through the high-altitude platform and then transmitted in a larger range through the satellite. The high-altitude platform can also increase the effective measurement and control range of the satellite ground station to the satellite, and increase the efficiency of the satellite network; in the high-altitude platform communication system, only one high-altitude platform can be deployed to play the role of a relay station. And a plurality of high-altitude platforms can be deployed according to different application scenes. Each platform can communicate with a ground terminal or a ground system, and can also communicate among the platforms to share, merge and forward data.

Compared with a ground wireless communication network, the high-altitude platform communication system has the following advantages:

(1) the covering capability is strong: the flight base station can provide coverage with the diameter of 400km, signals are mainly vertically transmitted, and the influence of the ground environment is small due to less blocking;

(2) the power efficiency is high: for most users, direct communication transmission is adopted, signal fluctuation is less, and propagation loss is small;

(3) the frequency spectrum efficiency is high: the method is beneficial to deploying beam forming and is more beneficial to improving the wireless spectrum multiplexing rate.

To achieve continuous coverage of an area, the network coverage of high-altitude platforms (e.g., powered aircraft) is similar to that of a ground cellular network, with certain overlap of the network coverage areas of adjacent high-altitude platforms, and the coverage area map formed by the high-altitude platforms on the ground is shown in fig. 1.

In the normal communication process, a high-altitude platform (a balloon, an airship or an unmanned aerial vehicle) moves in the air according to a designed track, so that the relative stability of the network topology can be basically maintained, or the network topology change can be predicted according to a preset flight track, and the network adjustment control is carried out.

Wireless transmission can be carried out between the high-altitude platforms. The aerial platform and the ground station can be connected through a wireless backhaul link and carry out backhaul or fronthaul operations. The ground terminal may have wireless access to the aerial platform. The ground stations can be connected with each other and accessed into a core network.

As shown in fig. 1, the terminal device in the coverage area may select to access to the high-altitude platform according to the received signal strength of the high-altitude platform, which is similar to the process of selecting to access to the ground station by the terminal and will not be described in detail herein.

Fig. 2 shows a flow chart of a method 100 of detecting a high altitude platform of an embodiment of the present invention. Ground station 0 is assumed to be connected to HAP-0, HAP-5, ground station 1 to HAP-1 and HAP-2, ground station 2 to HAP-3 and HAP-4, and ground stations adjacent to ground station 0 are assumed to be ground station 1 and ground station 2. As shown in fig. 2, the method 100 is described by taking as an example the detection of whether HAP-0 is malfunctioning and the malfunction or the measures taken, and the method 100 comprises the following steps:

s101, the ground station 0 sends state detection information to the HAP-0, and does not receive the response of the HAP-0 to the state detection information;

s102, the ground station 0 sends a state request to the ground station 1, the ground station 2 and the HAP-5, and the state request is used for acquiring the connection conditions of the ground station 1, the ground station 2, the HAP-1 to HAP-5 connected with the ground station 1 and the ground station 2, and the HAP-5 and the HAP-0;

s103, the ground station 1, the ground 2 and the HAP-5 respectively receive the state requests;

s104, the ground station 1 and the ground station 2 respectively determine whether the HAP-0 is accessed to the station;

s105, the ground station 1 and the ground station 2 respectively determine that the HAP-0 is not accessed to the station, the ground station 1 forwards the status request to the HAP-1 and the HAP-2, and the ground station 2 forwards the status request to the HAP-3 and the HAP-4, so as to confirm the connection condition of the HAP-1-HAP-4 and the HAP-0;

s106, HAP-1, HAP-2, HAP-3, HAP-4 and HAP-5 respectively receive the status request;

s107, determining whether to establish connection with HAP-0 or not by HAP-1, HAP-2, HAP-3, HAP-4 and HAP-5 respectively;

s108, HAP-1, HAP-2, HAP-3 and HAP-4 give the state information determined in S107 to the ground station 1 and the ground station 2 connected with the HAP-1, HAP-2 and HAP-4;

s109, the ground station 1 and the ground station 2 respectively receive the state information sent in S108;

s110, the ground station 1, the ground station 2 and the HAP-5 respectively send connection state information to the ground station 0;

s111, the ground station 0 receives connection state information sent by all adjacent ground stations and other high-altitude platforms connected with the ground stations;

s112, the ground station 0 performs OR operation on each state information in all the connection state information, and if the operation is 0, the HAP-0 is judged to be in fault; if the number is 1, judging that HAP-0 does not have fault, and assuming that 1 represents that connection is established with HAP-0;

s113, if the HAP-0 is judged to be in fault in the step S112, the ground station 0 confirms that the HAP-1, the HAP-2, the HAP-3, the HAP-4, the HAP-5 and the HAP-0 are adjacent high-altitude platforms according to the position information before the HAP-0;

s114, the ground station 0 acquires the current communication transmission loads of the HAP-1, the HAP-2, the HAP-3, the HAP-4 and the HAP-5 and the platform energy state, and performs network planning on the HAP-1, the HAP-2, the HAP-3, the HAP-4 and the HAP-5 again by combining the communication transmission loads before the HAP-0;

s115, the ground station 0 sends the planning information determined in S114 to HAP-1, HAP-2, HAP-3, HAP-4 and HAP-5;

s116, HAP-1, HAP-2, HAP-3, HAP-4 and HAP-5 receive the planning information sent by S115;

s117, the HAP-1, the HAP-2, the HAP-3, the HAP-4 and the HAP-5 move to corresponding positions according to the planning information, and the user switching is completed in the moving process;

and S118, reestablishing routing information by the HAP-1, the HAP-2, the HAP-3, the HAP-4 and the HAP-5 to complete network switching.

In the embodiment of the present invention, the high-altitude platform may carry the control base station to fly according to a predetermined trajectory, as shown in fig. 3, which is a sub-area of the high-altitude platform network. The area is centered on HAP-0, and surrounding high-altitude platforms HAP 1-HAP 6 can establish direct communication nodes with HAP-0. The corresponding coverage areas of the 7 high-altitude platforms on the ground are shown in fig. 1, wherein the middle area is the area covered by the HAP 0. The remaining regions correspond to HAP 1-HAP 6 in FIG. 3.

Those skilled in the art will appreciate that the airborne base stations carried by the high-altitude platform may be connected to ground stations via wireless backhaul links, and a ground station may be connected to one or more airborne base stations to establish backhaul links.

Suppose that ground station 0 is connected to HAP-0 and HAP-5 via wireless backhaul links at 10:00 am in beijing, ground station 1 is connected to HAP-1 and HAP-2 via wireless backhaul links at 10:00 am in beijing, and ground station 2 is connected to HAP-3 and HAP-4 via wireless backhaul links at 10:00 am in beijing.

The ground station 0 periodically sends state detection information to the HAP-0 to confirm whether the HAP-0 works normally. For example, ground station 0 may transmit the state detection information to HAP-0 once every 100ms, and ground station 0 may transmit the state detection information to HAP-0 once every 200 ms. Referring to the processing delay of the conventional wireless communication system, which is usually in the order of milliseconds, and specifically how long the request transmission period is, if not emphasized, the period duration of the embodiment of the present invention is not long enough to allow HAP-0 to move out of the range covered by the ground station 0 to the ground station 2, in other words, the period duration is long enough to allow the location of HAP-0 movement to remain within the communication range of the ground station connected to the high-altitude platform adjacent to HAP-0, and the embodiment of the present invention is not limited.

If the ground station 0 sends the state detection information to the HAP-0 in a period of 100ms, the ground station 0 sends the state detection information at 10:15 am in beijing, and does not receive the response of the HAP-0 to the state request after 100ms, the ground station 0 can temporarily determine that the HAP-0 moves out of the connection with the ground station 0 or that the HAP-0 may have a fault.

Ground station 0 sends a status request to ground station 1 and ground station 2 adjacent to ground station 0 in order to further determine whether HAP-0 has a fault, ground station 1 and ground station 2 may determine whether they have access to HAP-0 after receiving the status request, for example, may attempt to initiate a broadcast, and if not receiving a response from HAP-0 to them, may determine that they have not access to HAP-0; if the response of the HAP-0 to the HAP-0 is received, the HAP-0 can be judged to be accessed by the HAP-0.

When the ground station 1 and the ground station 2 respectively determine that the ground station 1 and the ground station 2 do not access to the HAP-0, the ground station 1 and the ground station 2 fail to feed back, the ground station 1 and the ground station 2 do not need to feed back to the ground station 0, the ground station 0 defaults that the ground station 1 and the ground station 2 fail to connect to the HAP-0, and the ground station 1 and the ground station 2 can respectively forward the state request to a high-altitude platform directly connected with the ground station 1 and the ground station 2. For example, ground station 1 forwards the status request to HAP-1 and HAP-2, and ground station 2 forwards the status request to HAP-3 and HAP-4. In addition, the ground station 1 and the ground station 2 can directly forward the state request to the high-altitude platform connected with the ground station without judging the connection condition between the ground station and the HAP-0.

Ground station 0 may also send a status request to other high-altitude platforms connected to itself, such as HAP-5, for obtaining status information whether HAP-5 and HAP-0 establish a connection.

HAP-1 to HAP-5 respectively receive the status request and determine whether the HAP-0 can directly communicate with itself according to the status request. For example, it may attempt to send a message to HAP-0, and if no response is received from HAP-0 to the message, it may determine that it cannot communicate with HAP-0; if a response to the message is received from HAP-0, it may be determined that it is possible to communicate directly with HAP-0.

The HAP-1 to HAP-4 respectively send the results of judging whether the HAP-0 can directly communicate with the ground station 1 and the ground station 2 which are connected with the HAP-1 through wireless mutual transmission links. HAP-5 may send the connection status information directly to ground station 0. The ground station 1 and the ground station 2 determine whether the high-altitude platform has communication with the HAP-0 after receiving the state information sent by the high-altitude platform connected with the ground station. For example, if no communication is determined, 0 is fed back, and if communication is determined, 1 is fed back. The ground station 8 can perform OR operation after acquiring the state information of the HAP-1 to HAP-5, if the state information is 1, the high-altitude platform or the ground station is communicated with the HAP-0, if the state information is 0, the high-altitude platform or the ground station is not communicated with the HAP-0,

if the result of the ground station 0 after carrying out or operation on all the state information sent by the ground station 1, the ground station 2 and the HAP-5 is 1, it indicates that at least one high-altitude platform or ground station can communicate with the HAP-0, and the HAP-0 can be eliminated from being in fault; if the result of the or operation of ground station 0 on all the status information sent by ground station 1, ground station 2 and HAP-5 is 0, it indicates that none of the high altitude platforms and ground stations are in communication with HAP-0, and it can be determined that HAP-0 is faulty.

After determining that the HAP-0 has a fault, the ground station 0 can determine the HAP-1-HAP-5 of the high-altitude platforms adjacent to the HAP-0 according to the position information of the HAP-0, which is acquired by the HAP-0 for the last time before the Beijing time is 10: 15. It should be understood that HAP-1 to HAP-4 directly connected to ground station 1 and ground station 2 adjacent to ground station 0 are also adjacent to HAP-0, or other high altitude platforms connected to ground station 0 are also adjacent to HAP-0, which is only schematically illustrated here, and the high altitude platforms connected to ground station adjacent to ground station 0 or other high altitude platforms connected to ground station 0 may not be adjacent to HAP-0, which is not limited in this embodiment of the present invention.

After determining that the HAP-0 has a fault, the ground station 0 can perform network planning again on the HAP-1-HAP-6. For example, the current communication transmission load and platform energy state of the HAP-1 to HAP-5 can be obtained, and the network planning can be carried out on the HAP-1 to HAP-5 again by combining the communication transmission load information before the HAP-0. For example, the HAP-0 provides network service for the terminal 1 and the terminal 2 before the failure, the HAP-1 to the HAP-6 currently provide network service for the terminal 3 to the terminal 15, and after the HAP-0 fails, the terminal 1 and the terminal 2 have no network service for a while, then the ground station 0 can redistribute the load according to the communication transmission condition of the terminal 1 to the terminal 15, so that the HAP-1 to the HAP-6 can cover the terminal 1 to the terminal 15. It should be understood that ground station 0 may also distribute loads based roughly only on the communication transmission load or platform energy status of each high-altitude platform, or ground station 0 may distribute loads to other high-altitude platforms based only on communication transmission loads prior to HAP-0. The ground station 0 may perform network planning again according to other information, and the embodiment of the present invention is not limited thereto.

The ground station 0 sends the planning information to the HAP-1-HAP-5, and specifically, the HAP-1-HAP-5 can receive the planning information through a path for receiving the status request. HAP-1-HAP-5 can move to corresponding positions after receiving, and can complete the switching of corresponding terminal equipment; the HAP-1 to HAP-5 can move to corresponding positions after being received, and can rebuild routing information among the HAP-1 to HAP-6, thereby completing network switching. And after the HAP-1 to HAP-6 are re-planned, the network coverage range of the HAP-1 to HAP-6 is expanded, and the original coverage range of the HAP-0 is covered by the HAP-1 to HAP-6. For example, terminal 1 and terminal 2 originally in the coverage of HAP-0 are covered by HAP-1 and HAP-2, respectively, and then terminal 1 and terminal 2 are accessed to HAP-1 and HAP-2, respectively; for another example, before the failure, HAP-1 and HAP-3 can not communicate directly, but communicate through HAP-0, so after the failure of HAP-0, HAP-1 and HAP-3 after the network planning is performed again can communicate directly, that is, there is routing information between them.

It should be understood that the user handover and the network handover are performed during the moving process similarly to the handover of the base station by the terminal device due to the failure of the base station or the handover of the connection relationship between the base stations in the terrestrial cellular communication. For the sake of brevity, this will not be described in detail here.

The method for detecting a high-altitude platform according to an embodiment of the present invention will be described below with reference to fig. 4 and 5, respectively, from the perspective of detecting other network devices with which the ground station interacts.

s210, when the first ground station is disconnected from the first high-altitude platform by a wireless link, the first ground station sends a state request to a first network device, wherein the state request is used for requesting to acquire connection state information, the connection state information comprises state information about whether at least one network device is connected with the first high-altitude platform, and the at least one network device comprises the first network device;

s220, the first ground station receives the connection status information sent by the first network device;

and S230, the first ground station determines whether the first high-altitude platform has a fault according to the connection state information.

Therefore, the method for detecting the high-altitude platform provided by the embodiment of the invention can be used for quickly detecting whether the high-altitude platform fails.

It should be understood that the first network device may be a ground station adjacent to the first ground station, or may be an aerial platform connected to an adjacent ground station via a wireless backhaul link, or the network device may be another aerial platform connected to the first ground station via a wireless backhaul link. For example, as shown in FIG. 2, HAP-0 and HAP-5 are connected to ground station 0, HAP-1 and HAP-2 are connected to ground station 1, ground station 1 is adjacent to ground station 0, ground station 0 is disconnected from HAP-0 at a certain time, ground station 0 may send the status request to HAP-5 and ground station 1, and the resulting connection status information includes HAP-1, HAP-2, HAP-3 and ground station 1 feedback of the status request.

The second ground station may be one or more, the second high-altitude platform may be one or more, and the third high-altitude platform may be one or more. The status information transmitted by each ground station may be one or more bits. For example, each high-altitude platform uses a bit to represent its communication status with the first high-altitude platform, and each bit may use 0 to represent no communication and 1 to represent communication, or 1 to represent no communication and 0 to represent communication. The second ground station may synthesize the state information of the second ground station and the second high altitude platform, and feed back the state information to the first ground station. The individual status information may also be fed back individually to the first ground station and integrated by the first ground station. The embodiment of the present invention is not limited thereto.

By knowing whether other network equipment is connected with the first high-altitude platform or not, the first high-altitude platform can be quickly detected to have a fault.
