Description
Technical Field
The invention relates to the technical field of satellite internet, in particular to a satellite network cell respiration processing method and system. In addition, an electronic device and a processor-readable storage medium are also related.
Background
The giant low-earth satellite constellation can provide high-capacity, low-latency, and full-coverage internet services for 33.8% of the population on earth that are inaccessible to terrestrial networks. However, since the birth of the satellite network, the satellite network has a problem of low utilization rate. It is important that the satellite is fully utilized. The most densely transmitted star link (Starlink) in the current constellation has transmitted 2653 satellites and obtained 33 national and regional service authorizations. A novel business model of the communication satellite is being tried, but the utilization rate of the satellite constellation is not only influenced by the business model, but also influenced by the constellation configuration and the user distribution, and the influence may form a bottleneck in the later development stage of the constellation, and the loss can be effectively reduced by considering the influence in the early stage of the constellation deployment and operation. In consideration of problems of satellite emission, orbit maintenance, relative motion of a satellite and the earth and the like, many existing low-orbit giant constellations adopt a uniform constellation configuration to provide internet services for ground users. But in practice, the ground users are highly unevenly distributed, with about 86% of the population being concentrated in 5% of the area. The areas such as oceans, deserts, forests and the like with rare people occupy most of the area of the earth, and the communication satellites are in a low-load or idle state when being empty in the areas, so that the utilization rate is very low. In contrast, the satellites in the dense area are congested due to insufficient capacity, and the congestion promotes the scale of the satellite constellation to be uniformly increased, so that the waste of idle satellites in the sparse area is further increased.
In the prior art, the wireless cellular network can perform load balancing and energy saving by changing the cell coverage area. Such a technique in which the base station adjusts the operating range according to its own load is called Cell breathing (Cell breathing) or Cell focusing (Cell focusing). The adjusting technology mainly comprises the following steps: physical adjustment, pilot signal strength adjustment, relay technology, association policy adjustment, and the like. However, for the existing centralized cell breathing processing scheme, because the giant constellation is large in scale and the coverage area of a single satellite is wide, the centralized scheme needs information of all users for central calculation, and therefore, the calculation cost is high; for the existing distributed community respiration processing scheme, because the satellite faces the user tide and the satellite motion reverse tide at the same time, the satellite load changes rapidly, but the distributed scheme can only be converged slowly, the adjustment speed is slow, and the community respiration failure is easily caused; meanwhile, the satellites move continuously, the relative positions of the satellites change continuously, the satellite combination which can realize global coverage cannot realize global coverage at the next moment, and the cell breathing may cause coverage holes to appear instead. Therefore, how to provide an effective cell respiration processing scheme to improve the efficiency of the satellite network becomes a difficult problem to be solved urgently.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, 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 application scene of the invention is a satellite network-based user terminal switching access satellite scene, and particularly relates to user terminal equipment and a satellite network. The satellite is used as an access point of the internet, and the ground user terminal can be directly associated with the satellite through a smart phone, a small handheld device and the like. As shown in fig. 2, there is overlapping coverage between the satellites, and once the user terminal enters the satellite network, a scanning operation is initiated and associated with the satellite having the strongest Received Signal Strength Indicator (RSSI). The user terminal may switch when a satellite with a strong RSSI appears or when the communication strength is insufficient due to a long distance from the satellite. In addition, the satellite described in the present invention can modify the pilot signal power, thereby controlling the operating range of the cell by controlling the pilot signal power. When the user terminal selects to connect with the satellite, the satellite with the strongest received pilot signal power is selected by default.
The following describes an embodiment of the method for processing the breathing of the satellite network cell based on the invention in detail. As shown in fig. 1, which is a schematic flow chart of a satellite network cell respiration processing method provided in an embodiment of the present invention, a specific implementation process includes the following steps:
step 101: dividing the target area into corresponding non-overlapping blocks according to the distribution density characteristics of the user terminals in the target area and the load capacity threshold of the satellite corresponding to the target area.
In the embodiment of the present invention, before performing this step, it is necessary to define related data in advance, for example, defining the most suitable received power of the ue as p, and a circle formed by points with the same received power in the satellite coverage area is called an isoline. When the satellite power is the highest, the area in the equal power line with the user terminal receiving power p is the coverage area of the satellite cell. Two satellites are considered to be adjacent satellites if their coverage areas overlap. For a satellite with power p', the area within the isoline with received power p within the coverage area of its cell is the operating range of the satellite cell. The received power of the user terminals in the operating range is greater than p. A user outside the operating range but within coverage may receive the satellite signal but, due to the lower power, the user terminal determines that the communication quality with this satellite is poor and will only choose to connect to this satellite if there is no other choice. For satellite s, if there is another active satellite s' whose coverage completely covers the minimum operating range of satellite s, s is considered as an alternative, and even if s can be dormant, the terrestrial user terminals can be served by the satellite, except that the received power may not reach s. The power is the pilot signal power.
In this step, firstly, the block division of the target area is performed according to the load capacity threshold of the satellite and the distribution density characteristics of the user terminal, that is, the target area is divided into a plurality of non-overlapping blocks by taking the user density or the user traffic density of the earth surface as the characteristics, so that the block size matched with the distribution density characteristics of the current user terminal is provided on the premise of ensuring the coverage. Specifically, according to a load capacity threshold of a satellite corresponding to the target area, the position grade of each position area is determined by taking the user density in the target area as a characteristic, and the target area is divided into blocks based on the position grades, so that adjacent position areas with the same position grade are divided into the same block, and different blocks corresponding to the target area are obtained. Specifically, before the target area is partitioned into blocks, a power level corresponding to a satellite in each area in the target area when the satellite reaches a preset load capacity threshold needs to be predetermined, and a position level of the corresponding area is determined based on the power level.
It should be noted that there are great differences between different areas of the ground, such as in an area where users are sparse (e.g., sea), where satellites are wasted, and in an area where users are dense, congestion occurs. And these types of regions are usually adjacent. For example, oceans without human smoke often border densely populated coastal metropolis. As a result, there may be significant differences in the cells of the satellites between adjacent regions, making it difficult to adapt quickly. The present invention first divides the ground into blocks according to the distribution density characteristics of the user terminals. For a satellite, each pilot signal power level corresponds to an operating range. At any position, the operating range of the satellite at different power levels of the pilot signal (i.e., the pilot signal power) and the number of users in the operating range can be calculated. When the users around the position are dense, the number of users in the satellite working range corresponding to the power level of the smaller pilot signal can reach the load capacity threshold of the satellite, and vice versa. In the practical implementation process of the invention, the power level corresponding to each satellite in each position when the satellite reaches the load capacity threshold can be recorded, the position level of the position can be set by referring to the power level, and the adjacent areas with the same position level are divided into the same block. For example: setting k power levels of the satellite, wherein each power level corresponds to the radius l of the working range i . The load capacity threshold of the satellite is Ψ o Traversing all the regions in the constellation that the satellite will pass through, for each location: first, count the position as the center of circle and take l 1 The user quantity in the circle with the radius is obtained, if the user quantity exceeds the load capacity threshold value, the position grade corresponding to the position is 1, otherwise, the statistics is continued to be carried out by l 2 The user amount of the area of radius until the load is exceeded or the rank power is maximized is set to the location rank k. Record the position rank of each position, all adjacent, bitsThe positions with the same rank are merged into a block to obtain a corresponding block. As shown in fig. 6, first, a pilot power (pilot signal power) is initialized to a preset maximum power, and it is determined whether a flow rate in a corresponding working range exceeds a load threshold (i.e., it is determined whether an actual load in the corresponding working range exceeds a corresponding load capacity threshold), if so, it is further determined whether the pilot signal power has reached a preset minimum power, if not, the pilot signal power is continuously reduced by one level, and finally, a current pilot signal power level is output as a position level.
Step 102: and determining the pilot signal power corresponding to the target satellite and the adjustment step size of the pilot signal power based on the movement characteristics of the target satellite in the block.
As shown in fig. 4, in the implementation of the present invention, when the target satellite moves in the current block, the current power state information of the previous satellite in the same orbital movement direction as the target satellite is used as the prediction information; adjusting a step size of the target satellite (i.e., an adjustment step size of the pilot signal power) based on a difference between the prediction information and an actual power of the target satellite; when the target satellite is switched to a new block from the current block, the pilot signal power of the target satellite is adjusted based on a preset initial power value corresponding to the new block. The preset power initial value is an inherent parameter of the block, specifically, a power average value of all satellites at the edge of the block after initialization; the current block and the new block are in adjacent relation.
It should be noted that, when the target satellite moves within the block, although the target satellite does not have extreme flow variation, the distribution of the user terminals in the block is irregular, and the neighboring satellites of the target satellite constantly change, so that the target satellite still needs to perform cell breathing.
The orbit period T of the existing low-orbit satellite constellation, which can be calculated according to equation (1):
in the formula, T e The earth rotation time; r is the radius of the earth; h is the orbital height of the satellite; g is gravity constant, M is earth mass, wherein GM is 397865.5km 3 /s 2 。
For a constellation with S satellites in one orbit, the time difference of two adjacent satellites in the same orbit passing through the same latitude is T/S. During this time, the rotation angle of the earth is 2 pi T/(T) e S), only 1 degree exists for Starlink, so that the difference between service areas of two adjacent satellites in the same orbit is small; in addition, due to the uniform configuration of the constellation, when two adjacent satellites in front of and behind the same orbit pass through the same latitude, the power states of the adjacent satellites are relatively similar. Therefore, when the target satellite is not converged timely due to the changes, the current power state of the previous satellite in the same orbit moving direction can be used as prediction information or a target state predicted by the target satellite, and the step length of the current target satellite is set according to the difference value between the current power state and the target state, so that rapid convergence is realized, for example, the step length is adjusted to the difference value/time of the sizes of two satellite cells. In each time slice, the current power state of the previous satellite in the same orbit moving direction is recorded, and is compared with the power state of the target satellite to calculate a corresponding difference, for example, the time for moving from the current orbit position to the next orbit position is t, and the power state difference is Δ p, so that the step length of the power change of the satellite can be adjusted to be Δ p/t, namely the power is increased by Δ p/t or decreased by Δ p/t. The complete process of implementing dynamic cell adjustment is shown in fig. 8, where the new region is a new block, and the initial power of the new region is a preset initial power value corresponding to the new block, and the detailed process is not repeated here.
In addition, it should be noted that although the target satellite predicts the current power state of the previous satellite in the same orbit moving direction, the current power state of the previous satellite is not completely followed, and the speed of the power change of the target satellite is adjusted according to the difference between the current power state and the actual power of the target satellite, that is, the target satellite can determine how to adjust the step size according to the power state information of the adjacent satellite, thereby improving the flexibility of adaptation and the prediction accuracy.
Further, as shown in fig. 5, when the target satellite is handed over between two blocks, since the difference of the user terminal density between the blocks is usually very large, the cell modification step size is still not fast enough to adapt to the change quickly, so the parameter of the preset power initial value is introduced in the embodiment of the present invention. When the target satellite enters the designated block, the size of the initial cell of the target satellite is directly set as the preset power initial value of the area. Such as: when the target satellite enters a new block, the cell size of the target satellite is directly initialized to the preset power initial value size specified by the new block to quickly adapt to the load of the new block. It should be noted that, even in the same block, there is a difference in the distribution of users, and the power levels of satellites in the same block are different, so that the power of a satellite over the area cannot be directly applied to the initial value setting of the area. Since the preset power initial value of the area is used for initial power setting when the target satellite newly enters the sector, the preset power initial value of each sector is set as an average value of satellite power at the edge of the sector after initialization.
Before the step, a satellite network cell initialization scheme is designed, and optimal initial parameter value setting and step length adjustment are carried out according to factors such as population density, flow distribution and time, so that the coverage radius of the block is set by the satellite according to the density characteristic of the block, and the number of the participating satellites can be determined by the adjustable radius. Namely, before determining the pilot signal power and the power adjustment step size corresponding to the target satellite based on the movement characteristics of the target satellite in the block, the initialization phase of the satellite cell is also included. The initialization process of the satellite cell comprises the step of carrying out cell initialization operation on the pilot signal power of the target satellite based on the load information between the target satellite and the adjacent satellite. The performing cell initialization operation on the pilot signal power of the target satellite based on the load information between the target satellite and the adjacent satellite specifically includes: determining a load capacity threshold corresponding to a satellite in advance; the satellite includes the target satellite and the neighboring satellite; in the cell initialization process of the target satellite, determining initial pilot signal power corresponding to the target satellite based on the relation between the actual load of the target satellite and the corresponding load capacity threshold and the relation between the actual load of the adjacent satellite and the corresponding load capacity threshold, and controlling the cell initial coverage radius of the target satellite by determining the magnitude of the initial pilot signal power.
Wherein, the initial pilot signal power (initial value of pilot signal power) corresponding to the target satellite is determined based on the relationship between the actual load of the target satellite and the corresponding load capacity threshold and the relationship between the actual load of the adjacent satellite and the corresponding load capacity threshold, and the working range of the cell is controlled by controlling the magnitude of the pilot signal power, and the corresponding implementation process includes: when the actual load of the target satellite reaches or exceeds a corresponding load capacity threshold value and the actual load of the adjacent satellite corresponding to the target satellite is lower than the corresponding load capacity threshold value, controlling to reduce the initial pilot signal power corresponding to the target satellite so as to reduce the cell initial coverage radius of the target satellite to reduce the actual load of the target satellite; or, when the actual load of the target satellite is lower than the load capacity threshold and is not 0, and the actual load of the adjacent satellite corresponding to the target satellite reaches or exceeds the corresponding load capacity threshold, controlling to increase the initial pilot signal power corresponding to the target satellite according to a preset proportion so as to enlarge the cell initial coverage radius of the target satellite to reduce the actual load of the adjacent satellite; or when the actual load of the target satellite is 0 and the current working range of the target satellite is covered by the working range of the adjacent satellite, adjusting the initial pilot signal power of the target satellite to 0, controlling the target satellite to enter a dormant state, and notifying the adjacent satellite corresponding to the target satellite; the initial pilot signal power is an initial value of the pilot signal power determined after the target satellite performs cell initialization operation; the initial coverage radius of the cell is used for determining the working range of the target satellite. Fig. 7 shows a complete flow for determining the initial pilot signal power, where the threshold is a load capacity threshold, and the pilot frequency is the pilot signal power, and the detailed process is not repeated here.
It should be noted that the pilot signal power of the satellite has multiple levels, and the difference between the pilot signal powers of each level is called a step size. In the initialization stage, the satellite adjusts the power of the pilot signal by a fixed step length, and each step of adjustment is carried out, the user reselects to access the satellite according to the adjusted power of the pilot signal. The satellite adjusts multiple times until it converges to a relatively stable value.
In order to ensure global coverage, each satellite has a minimum working range, and when the working ranges of all the satellites are set to be the minimum working ranges, it is required to ensure that the receiving powers of all the user terminals exceed a threshold, that is, the working ranges of the satellites are required to cover all the user terminals. Fig. 3(a) and (b) show the conditions that the minimum working range of the satellite needs to satisfy at different relative positions of the satellite. The radius of the earth is R, and for a constellation of P orbits, each orbit having S satellites, the range radius l should satisfy for the relative positions of the satellites of fig. 3:
when the load is heavier during adjustment, the pilot signal power is reduced to reduce the size of the cell; when the load is light and the satellite load of the neighbor is heavy, the cell size is increased; when the satellite is idle and is replaceable, it goes to sleep.
In the practical implementation process of the present invention, the initialization process of the satellite cell is used to determine whether the target satellite can sleep. Setting a load capacity threshold for a target satellite to Ψ o . When the actual load of the target satellite reaches or exceeds the load capacity threshold, the target satellite is considered to be overloadedAnd (4) heavy. In each adjustment, the target satellite negotiates with its neighboring satellites to determine the adjustment direction of the cell size according to the load condition. In the negotiation, for each satellite: if the load of the target satellite is 0 and the target satellite can replace the load, the target satellite does not cause coverage blind areas or user congestion when in sleep, so the satellite adjusts the power of the pilot signal to 0 and enters a sleep state; when the target satellite load reaches or exceeds the preset load capacity threshold psi o And the load of the adjacent satellite does not exceed the preset load capacity threshold psi o The load can be reduced by reducing the working range of the target satellite without causing congestion of other adjacent satellites, so that the power of the pilot signal of the target satellite can be reduced by one step; when the actual load of the target satellite is lower than the preset load capacity threshold psi o And the actual load of the existing neighboring satellite exceeds the preset load capacity threshold Ψ o The power of the pilot signal of the current target satellite is increased by one level, and the working range is expanded, so that the load of the adjacent satellite is shared.
Aiming at the whole satellite network (or constellation), the invention can quickly determine the proportion of the dormant satellites, greatly reduce the number of active satellites and effectively reduce the congestion proportion. From the load perspective, the satellite in the invention is not only fully loaded when passing through the dense area, but also distributes the load of the dense area when surrounding the dense area, thereby reducing the congestion. In the aspect of adjusting speed, the method can realize adjustment of extreme differences facing different sub-blocks through block division on one hand, and can realize trend adjustment through adjusting step length on the other hand, so that the method has better performance.
In the embodiment of the invention, a self-adaptive cell breathing dynamic adjustment mechanism is designed, the coverage radius of a cell is adjusted through user flow density, and an initial value of pilot signal power of a cell satellite (namely the initial coverage radius of the cell) and an adjustment step length of the pilot signal power are set according to the characteristics of the user flow density until a coverage hole appears.
The satellite network cell respiration processing method provided by the embodiment of the invention can be used for rapidly adapting to flow change on the premise of ensuring coverage, reducing the influence of adjacent satellite change, realizing extreme difference of different sub-blocks through block division, realizing trend adjustment through adjusting the step length, having better performance, improving the overall utilization rate of a satellite internet under the condition of satellite-oriented rapid motion, and rapidly selecting effective pilot signal power and power adjustment step length through the moving condition of a target satellite in the block to determine the convergence range of power, realize effective trend adjustment and achieve the optimal solution of regional satellites.
