Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes a deployment method, a device and electronic equipment of an air network system according to the present invention with reference to fig. 1 to 4.
In the scene of emergency communication after disaster, the following problems still exist in the related research of interruption compensation coverage through an aerial base station in the prior art. In some researches, compensation problems in a post-disaster emergency communication scene are researched by taking the maximum coverage area as a target, but a multi-air base station deployment strategy based on user equipment distribution and energy efficiency is not considered. Even though energy efficiency maximization is achieved through coverage maximization and power control, joint application of different types of air communication facilities is not considered.
In addition, because of the enhancement of local area hot spots in the emergency network, the performance and capacity enhancement of the hot spot area is also lacking in the emergency scene.
The deployment method of the air network system provided by the embodiment of the invention designs an emergency air network deployment architecture consisting of an air base station and an air radio frequency unit. And then, constructing a problem model by taking high energy efficiency as a target, splitting and solving the problem model, and optimizing the deployment of the aerial base station through a related algorithm, thereby solving the coverage problem of an interruption area and the enhancement of local capacity. On the basis, the throughput of the user data is analyzed by acquiring the user data, resources of the air base station are reasonably distributed, and energy efficiency optimization is achieved. The deployment method of the air network system provided by the embodiment of the invention can quickly build an emergency network through the air base station under the condition that the existing hardware equipment can not be used continuously, thereby realizing the coverage recovery of a communication network and the capacity enhancement of a local hot spot area.
The execution subject of the deployment method of the air network system in the embodiment of the present invention may be a control center, and in some embodiments, may also be a controller, and the execution subject is not limited herein. The following describes a deployment method of the air network system according to an embodiment of the present invention, with a control center as an execution subject.
It should be noted that the control center is used for emergency deployment of the post-disaster communication system, and the control center can receive input from a user and issue related instructions to related facilities. Or, the control center can also automatically issue related instructions to related equipment according to the existing strategy.
As shown in fig. 1, the deployment method of the air network system according to the embodiment of the present invention mainly includes step 110 and step 120.
At least one first base station is deployed over the air in the target area based on a target map of the target area, step 110.
The target area may be an area that is subjected to a disaster, or an area in which emergency communication needs to be resumed after a disaster.
The target map includes facility distribution information of the target area and historical user terminal location information.
Facilities of the target area include various sites and distribution areas of buildings, for example, facilities may include roads, squares, open spaces, and different types of buildings.
The historical terminal location information includes access point locations for various types of user terminals in the target area. The user terminal can be a mobile phone, a computer, a tablet, a special emergency device and the like.
In some embodiments, the target map of the target area may be first mapped by a satellite or drone.
For example, the target area may be scanned with a patrol drone. The scanning mode is that the unmanned aerial vehicle continuously shoots high-definition images on the disaster area along a fixed direction, speed and height. In this case, the photos taken every two times must maintain a certain overlapping area to ensure that the images can be completely spliced, thereby obtaining a complete and accurate map of the target area.
The historical ue location information of the target area may be obtained by retrieving the communication information of all ues collected by the base station in the past.
After the position information of the historical user terminal is obtained, the position of the historical user terminal can be marked on the obtained target map of the target area through related software, so that the position information of the historical user terminal accessing the network system can be conveniently obtained through analysis.
It should be noted that different facilities in the target area may have different numbers of user terminals and may have different communication requirements in an emergency scenario.
For example, user terminals are typically distributed and concentrated at residential building locations, requiring a larger capacity of transmission resources, while communication needs to be smaller at open air and square locations. When a disaster such as an earthquake or a fire occurs, the number of terminals of users at the location of a residential building is drastically reduced, and people are gathered at safe locations such as a stadium, a square, and an open space. In this case, the position of the hot spot of the target area changes, and thus the position to be deployed also changes.
In this embodiment, in order to recover the communication of the terminal in time, at least one first base station may be deployed in the air of the target area based on the target map of the target area.
The first base station can be deployed in an area with densely distributed historical user terminal positions, and meanwhile the undeployed position of the first base station is properly corrected in consideration of the current actual emergency scene.
For example, in the case of an earthquake or a fire, the first base station may be disposed in the air at a position close to the open space or the square, in consideration of the spread of people to open and flat areas.
In case of flood, the first base station may be deployed over a location near a high-rise building in consideration of the transfer of people to the high-rise building.
That is, in the embodiment, the deployment position of the first base station is determined comprehensively in consideration of both the position information of the historical user terminal and the influence of different disaster types on the crowd distribution, and then the related deployment instruction is sent to the related device to complete the deployment.
The first Base Station is an emergency public mobile communication Base Station, and may be an air Base Station (AeBS) in the present embodiment. The first base station is a radio transceiver station which can carry out information transfer between a mobile communication switching center and a terminal in a certain radio coverage area. The baseband part and the radio frequency part of the base station may be separated. The baseband part can be called a baseband processing unit, the radio frequency part can be called a radio remote unit, and the baseband processing unit and the radio remote unit can be connected in a wired optical fiber or wireless mode.
It can be understood that the deployment cost of the first base station is high, and the coverage of the target area partial area can be realized only by deploying a certain number of first base stations, and some coverage gaps and marginal areas still cannot realize emergency communication.
And step 120, deploying at least one radio frequency unit in the air of the target area based on the target map and the coverage area of the first base station.
It is understood that the Radio unit in this embodiment may be an air Radio unit (aerorrh). The air radio frequency unit has no baseband processing unit and cannot work independently.
The baseband processing unit of the first base station may support a plurality of remote radio units, i.e., a plurality of over-the-air radio units. In this embodiment, a baseband signal is transmitted between the air radio frequency unit and the baseband processing unit, the baseband processing unit may send the baseband signal to the air radio frequency unit, the air radio frequency unit may convert the baseband signal into a radio frequency signal and transmit the radio frequency signal through an antenna, and the air radio frequency unit may further receive the radio frequency signal through the antenna, convert the received radio frequency signal into a baseband signal, and send the baseband signal to the baseband processing unit.
The radio frequency unit is in communication connection with the first base station, and can be continuously deployed at the gap position and the edge position covered by the network through a target map and the coverage area of the first base station to realize the coverage of the whole domain of a target area.
In this case, the global communication coverage can be realized in the target area by the first base station and the radio frequency unit.
According to the deployment method of the air network system provided by the embodiment of the invention, the first base station is deployed firstly by analyzing the target map of the target area and the position information of the historical user terminal, the emergency communication of most positions in the target area is ensured at the highest speed, and then the communication coverage of the gap and the edge position is carried out by arranging the radio frequency unit, so that the full-fast communication coverage of the target area is realized, and the large-area continuous network service of the target area is ensured.
In some embodiments, after deploying at least one radio frequency unit over the air in the target area based on the target map and the coverage area of the first base station, the method further comprises: and acquiring the transmission information quantity of the user terminal and the position information of the user terminal in the target area through the first base station and the radio frequency unit.
It can be understood that after the first base station and the radio frequency unit are deployed, the communication of the target area is recovered, and the user terminal can access the temporarily built air network system for communication.
In this case, the transmission information amount of the user terminal and the location information of the user terminal in the target area acquired by the first base station and the radio frequency unit may be collected.
Due to the transfer and activity of people, the traffic volume of partial areas is increased, and the communication requirement of the target area is difficult to meet through the existing technology and equipment. Too high population density can create regional traffic hotspots caused by user aggregation.
The users gathered in the hot spot area are called hot spot gathering users, and for a hot spot area, the closer to the central position, the higher the gathering degree of the users. Assuming that all users move in a horizontal space, from the perspective of probability statistics, the position distribution of the hotspot-gathered users conforms to a law of large numbers and obeys two-dimensional Gaussian distribution. When a plurality of hotspots exist simultaneously, the distribution of the hotspot aggregation user follows a Gaussian Mixture Model (GMM).
In some embodiments, determining the hotspot location is accomplished by enhanced GMM-based greedy EM algorithm for hotspot region location monitoring.
In other embodiments, the location where the user terminals are densely distributed and where the amount of transmission information is large may be determined as the hotspot location based on the amount of transmission information and the location information of the user terminals, in which case at least one hotspot location may be determined in the target area.
After determining the hot spot locations, a second base station may be deployed over the air at each hot spot location. In this case, by deploying the second base station, local performance improvement and capacity expansion of the hotspot position can be achieved, and thus stable and continuous network service is better provided for the target area.
In some embodiments, the first base station and the radio frequency unit both communicate over a legacy band and the second base station communicates over a millimeter-wave band.
In other words, the second base station is a millimeter wave base station. In this case, the millimeter wave base station can provide sufficient bandwidth, low latency, and high capacity communication support.
Millimeter waves have the advantage of large bandwidth, the bandwidth is the most important resource in communication, and the simplest way to realize higher download rate is to widen the bandwidth. The millimeter wave has a large bandwidth ranging from 24GHz to 100GHz, which is 25 times more than the bandwidth used by the current 3G/4G, and the rate can be conveniently improved.
Millimeter waves have the advantage of low latency. The millimeter wave technology supports reducing the time length of the sub-frame, can transmit the information in a short time, and can feed back the received information or not to receive the information quickly, thereby reducing the communication time delay.
Millimeter waves also have the advantage of large capacity. If there are hundreds of people in a wide area, or thousands or even tens of thousands of people in a stadium, a large number of users download data simultaneously, the bandwidth and download rate requirements for wireless communication are different than if only a single user downloaded. The millimeter wave can well meet the wireless communication requirements of a large number of users and provide larger capacity.
Under the condition, the millimeter wave base station can provide faster and more stable network service for the hot spot position, and further can better meet the communication requirement of special areas of emergency scenes.
In some embodiments, the first base station is deployed with an airship as a carrier, and both the radio frequency unit and the second base station are deployed with a fixed wing aircraft as a carrier.
It should be noted that, in order to implement the aerial deployment of the base station, the deployment may be performed by using an unmanned aerial vehicle.
The drone types may be divided into rotorcraft, fixed-wing aircraft, and airship. The rotorcraft has the advantages that the payload capacity is tens of grams to 7 kilograms, enough communication units cannot be carried, the autonomous capacity is relatively low, the rotorcraft can only operate for a few minutes at low altitude, and the rotorcraft is not suitable for being used in the scene of post-disaster network repair.
Fixed wing aircraft have sufficient payload capacity to allow trajectory management and positioning. Compared with a rotor craft, the self-contained type aircraft has the advantages that the self-contained type aircraft is generally stronger, the working time can reach about 1 hour, the self-contained type aircraft can be used for carrying a network module, the deployment speed is high, and the cost is easy to control.
Airships and balloons are classified as aerostatic platforms that float in the air using buoyancy. It is very flexible in terms of both loading and autonomy, and can fly and stay in the air for a long period of time at a distance of 200 m to 30 km from the ground.
Thus, the first base station location does not substantially change, taking into account the specifics of the different communication facilities, and an airship may be employed to deploy the first base station. In consideration of the change of the position of the hot spot and the flexibility of the deployment of the radio frequency unit, the second base station and the radio frequency unit can be deployed by using a fixed wing aircraft as a carrier.
In the embodiment, the proper carriers are selected for different types of network equipment to deploy the network equipment, so that normal deployment of the network equipment can be ensured, and the communication requirement of a target area is further met.
As shown in fig. 2, fig. 2 illustrates a deployment scenario in which network coverage of a specific area is achieved by an AeBS, an AeRRH, and a mmW-UAV (millimeter Wave UAV).
In some embodiments, after deploying the second base station over the air at each hotspot location, the method comprises: determining deployment costs of all first base stations, all radio frequency units, and all second base stations.
It can be understood that, in order to avoid the problem of over-coverage and resource waste caused by over-deployment to reduce the deployment cost, statistics may be performed on the deployment cost of the communication facilities that have already been deployed, and the deployment mode of the communication device may be adjusted on the premise of satisfying the communication coverage to reduce the deployment cost.
In some embodiments, determining the deployment costs of all first base stations, all radio frequency units, and all second base stations comprises: determining deployment energy consumption cost based on the initial transmitting power of all the first base stations, the initial transmitting power of all the radio frequency units and the initial transmitting power of all the second base stations; determining a deployment hardware cost based on the hardware costs of all first base stations, the hardware costs of all radio frequency units, and the hardware costs of all second base stations.
Since the deployment cost of the communication facility includes the deployment energy consumption cost and the deployment hardware cost, the deployment energy consumption cost and the deployment hardware cost can be superimposed to determine the deployment cost.
In the embodiment, the deployment cost of the network facility is counted, so that the deployment mode of the network facility is conveniently adjusted, and resources are saved.
After determining the deployment cost of the network facility, the deployment heights, the transmission powers and the channel allocation information of all the first base stations, all the radio frequency units and all the second base stations may be re-determined based on the deployment cost and the transmission information amount and the location information of the user terminal.
In this case, the highest energy efficiency can be achieved by adjusting the deployment heights, power allocation, and channel allocation of various types of network facilities, thereby realizing resource saving.
In some embodiments, the optimal solution of resource allocation may be determined by establishing a deployment resource optimization problem model to solve the deployment patterns of the respective network facilities.
In this embodiment, the channel allocation calculation requirement increases significantly if the number, height position and transmission power of the various network facilities are uncertain.
In an emergency scene, the priority of rapid recovery communication is higher than that of capacity promotion optimization, advanced coverage recovery can be realized, network deployment is optimized, network coverage of a target area is ensured rapidly, resource allocation is adjusted, and deployment cost is reduced.
