Description

Communication method, device and computer readable storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communications method, an apparatus, and a computer readable storage medium.

Background

Low-orbit satellite constellations have become a hot trend in recent years for satellite communications. In order to achieve both global seamless coverage and hot spot high capacity, more and more low-orbit satellite communication systems are adopting a constellation configuration of mixed polar and oblique orbits. Wherein, the general polar orbit deployment guard is used for realizing global coverage; oblique orbiting satellites are used to achieve capacity enhancement in hot spot areas.

In view of the limited frequency resources that can be used by satellite communications, satellites in different orbital layers tend to use the same frequency multiplexing manner to increase the utilization of frequency resources. However, the same frequency multiplexing brings interference problem, and needs to be reasonably solved. As shown in fig. 1, assuming that a low-orbit constellation system is composed of M polar satellites and N oblique satellites, the terminal a can simultaneously receive signals of the polar satellites S ₁ and the oblique satellites S ₂, because S ₁ and S ₂ use the same-frequency multiplexing, if the terminal a currently communicates with the polar satellites S ₁, the oblique satellites S ₂ will cause interference to the communication between the terminal a and the polar satellites S ₁; similarly, if terminal a is currently communicating with the polar orbit satellite S ₂, then the oblique orbit satellite S ₁ would interfere with the communication between terminal a and the polar orbit satellite S ₂.

Since the satellites in heterogeneous orbits operate in the same frequency mode, in order to maintain capacity and avoid interference, the simplest way is to use only one layer of constellation to cover the same area, for example, only polar satellites are used to cover areas close to the high latitude of the earth, while in other latitude areas the polar satellites are normally turned off to only reserve the tilting satellites to provide service. However, for the same-frequency heterogeneous constellation system, the interference avoidance method which only uses one layer of constellation to cover wastes the polar orbit satellite resources of middle and low latitudes, and the system cannot obtain the maximum capacity. For example, the communication capacity of a satellite constellation is generally calculated by multiplying the single-satellite capacity by the number of satellites, and for the heterogeneous constellation shown in fig. 1, assuming that the single-satellite capacity is B, the total capacity of the system in which all satellites function is (m+n) ×b, and if L (L < M) satellites are turned off at low and medium latitudes, this means that the system will lose the capacity l×b, resulting in resource waste. Particularly, for some densely populated middle-low latitude areas, after the polar orbit satellite service is closed, the polar orbit satellite service can only be provided by the inclined orbit satellite, so that the load of the inclined orbit satellite is overlarge, and the full utilization of the whole network resource is not facilitated.

Therefore, under the condition of relatively tense frequency resources, aiming at the same-frequency heterogeneous orbit satellite system, how to fully utilize all satellites to work for more users and reduce interference among satellites in different layers is a main research direction of related technicians.

The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in embodiments of the present application means two or more, and other adjectives are similar.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The embodiment of the application provides a communication method and a communication device, which are used for fully utilizing satellite resources and reducing interference among satellites in different layers of orbits.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

Referring to fig. 2, fig. 2 is a flowchart of a communication method according to an embodiment of the present application, as shown in fig. 2, including the following steps:

In step 201, in the multi-layer heterogeneous orbit satellite communication system, the network device forms a plurality of independent wave positions on the ground.

In the embodiment of the application, the multi-layer heterogeneous orbit satellite communication system consists of multiple layers of orbits, the satellite coverage areas of different layers of orbits are different, independent coverage areas exist between the satellite coverage areas, and overlapping coverage areas also exist. In the satellite communication system according to the embodiment of the present application, all satellites use the hopping beam, where the fixed beam can be regarded as a special form of the hopping beam, and all satellites in the system can use the same frequency band, i.e. can be configured to the same frequency band.

In the embodiment of the present application, in order to increase flexibility, the network device may form a plurality of independent wave positions to the ground in at least the following two manners:

the first approach may be referred to as a fixed-wave-position configuration. In this way, the network device forms a plurality of independent wave positions on the ground according to the setting parameters, wherein the plurality of independent wave positions are adjacent to each other, and different wave positions correspond to different geographic positions. Wherein the setting parameters include one or more of the following information: ephemeris parameters, beam size, beam configuration. That is, the wave position is associated with a geographical position, and the wave position is relatively fixed to the earth surface. In practical applications, longitude and latitude coordinates or other information of the center of a wave position can be used to indicate a certain wave position.

Specifically, the network device forms a plurality of independent wave positions on the earth surface according to the ephemeris parameters, the beam configuration, the beam size and other information of the multi-layer orbit satellite, and the wave positions are adjacent to each other to realize the coverage of the ground. The network equipment configures different accessible wave positions for satellites of different orbit types in the multi-layer orbit overlapping area according to the wave beam quantity, the size, the hopping mode and the like of the satellites of different orbit layers, so that the communication coverage rate can be met in the overlapping coverage area, and the hopping wave positions of the satellites of different orbit layers can be realized to be non-overlapping.

The network equipment configures an accessible wave position list for the overlapping coverage area of the multi-layer satellite, and only one type of satellite is required to be accessed at the same time by the same wave position. For a single-layer constellation coverage area, such as an earth high-latitude area covered by a polar orbit satellite, the network equipment plans a beam access rule of the polar orbit satellite, so that beams of different satellites are prevented from overlapping with each other.

The second approach may be referred to as dynamic wave position configuration. In this manner, the network device determines an overlapping coverage area between satellites of different orbit types based on the movements of the satellites of different orbit types, and then divides the overlapping coverage area into a plurality of independent wave positions. That is, the relationship between the wave position and the geographic position is not fixed, and the wave position is divided from the viewpoint of the satellite. With the movement of satellites of different orbit types, the wave positions corresponding to the movement of the satellites of different orbit types change. The wave position configuration of the satellite and the current moment jointly indicate the coverage area of the satellite at the current moment. For example, the coverage area of the first target satellite at the current moment is determined according to the current moment and the wave position access information, and the first target satellite is any satellite of satellites with different orbit types.

Taking conical beams with the same beam sizes of satellites in different orbital layers as an example, the surface of the earth is configured into a plurality of adjacent wave positions according to the curved surface size of a beam coverage area, so as to realize the coverage of the surface of the earth. For example, starting from two poles, for example, taking the northern hemisphere as an example, taking the north pole as the center, disposing the first wave position, disposing 6 wave positions in the second circle taking the first wave position as the center, disposing 12 wave positions (which may be different) in the third circle, disposing 18 wave positions in the fourth circle, and the like, wherein the number of wave positions in one circle with the center point on the equator is the largest. The wave position configuration of the southern hemisphere is similar to that of the northern hemisphere. As shown in fig. 3 (a), a two-dimensional plan view of a beam wave position is shown, and fig. 3 (b) is a three-dimensional perspective view of a wave position configuration.

Step 202, the network device sends wave position access information to satellites with different orbit types.

Specifically, in this step, the network device configures different accessible wave positions for satellites of different orbit types according to reference information, where the reference information includes one or more of network loads and a number ratio between satellites of different orbit types in a ground area. And then, the network equipment forms wave position access information and transmits the wave position access information to satellites of different orbit types.

Wherein the wave bit access information includes:

time information for representing effective time information of the wave bits;

The wave bit identifier is used for uniquely identifying the wave bit;

In this step, the network device may form the information of the accessible wave bits into the form of an accessible wave bit list and signal to all satellites of the whole network.

On the basis of the above embodiment, in order to facilitate distinguishing between different wave positions, the network device may further set an identifier for the plurality of independent wave positions.

In the embodiment of the present application, for the above fixed wave position configuration, the network device may set identifiers for a plurality of independent wave positions according to the arrangement sequence of the wave positions, or set identifiers for a plurality of independent wave positions according to the geographic direction corresponding to the wave positions and the relative positions of the wave positions in the plurality of independent wave positions. For the dynamic wave position configuration, the network device may set identifiers for a plurality of independent wave positions respectively based on the sequence from the center to the periphery with the wave position where the second target satellite is located currently as the center, where the second target satellite is any satellite of satellites with different orbit types.

Because the coverage azimuth of the jumping beam is relatively concentrated, the beam diameter is between tens of kilometers and hundreds of kilometers, the number of wave positions configured on the ground surface is large, and the wave positions need to be ordered. In the embodiment of the application, the arrangement of the wave positions can be realized in at least the following two ways.

(1) Arrangement for fixed wave position

One way is to identify N wave positions from 1,2, 3 … …, N by sequential arrangement. Another way is to use an arrangement method of the identification direction. For example, north by "N", south by "S", east by "E", west by "W", for example: "N0E3" means the 0 th turn of the northern hemisphere and the 3 rd wave position on the eastern side. The 0 th circle represents that the wave position central point is on the equator, and the east-west azimuth configuration can be configured according to the geographic longitude and latitude and can also be customized.

(2) Arrangement for dynamic wave positions

The dynamic wave positions are divided from the satellite angle, so the wave positions can be orderly arranged from the center to the periphery.

In the embodiment of the present application, a two-layer track constellation is taken as an example, where the two-layer track is a polar track and an inclined track respectively. Polar orbit constellation is characterized by north-south motion, passing through the earth's two-polar region; the oblique orbit constellation is characterized by not passing through the earth's dipolar region.

In low latitude areas, overlapping coverage of the oblique orbit satellite and the polar orbit satellite is serious, different access wave positions can be configured for different types of orbit satellites in order to avoid interference caused by overlapping coverage and same-frequency operation, the accessible wave position of the polar orbit satellite cannot be accessed, and the accessible wave position of the oblique orbit satellite cannot be accessed.

The configuration mode of the accessible wave position can be based on network load, average number proportion of different satellites in the area and the like. Taking the configuration mode of the average number proportion of different types of orbit satellites in the area as an example, assuming that the visible proportion of the inclined orbit satellites to the polar orbit satellites in the area is 5:2, the accessible wave bit configuration is shown in fig. 4. According to the average quantity proportion of the two types of orbit satellites in the current area, configuring 42 wave positions into 2 classes, wherein 30 wave positions can be accessed by the inclined orbit; polar satellites have access to 12 wave positions.

With the above configuration, a wave bit access table can be formed. The wave bit access table contains 3 main elements: time period, wave bit sequence number, type of satellite accessible. Wherein, the time period: representing an effective time interval; wave position number: a number representing the accessible wave position; the type of satellite that can be accessed: indicating the type of satellite that can access the wave position, e.g., polar orbiting satellite, oblique orbiting satellite, etc. For two layers of orbits "0, 1" can be used to distinguish between different satellite types, e.g. "0" for polar orbit satellites and "1" for oblique orbit satellites.

In practical applications, the network device may also periodically update the configured state of the accessible wave bit table according to the state of the multi-layer satellite constellation, and signal each satellite. For example, the network device periodically updates the accessible wave bit table according to the working state of the multi-layer heterogeneous satellite constellation, the whole network load distribution state, and the like.

In addition, the network device may also notify the terminal of the service satellite type of the wave position where the terminal is located in a signaling (such as RRC (Radio Resource Control, radio resource control) signaling, etc.), if the service satellite type of the wave position where the terminal is located changes, whether the wave position configuration attribute of the network device changes or the service wave position caused by the movement of the terminal changes, the wave position of the terminal will be switched. Specifically, the network device may periodically adjust the contents of the beam access table according to the operation state of the whole network, and then notify the whole network in a signaling form. For the wave bit with changed access satellite type, if there is a terminal in connection state, the network device needs to inform the terminal that the satellite type of the wave bit service is changed, and provide updated information such as satellite type, beam parameters and the like for the terminal in signaling form.

For the terminal, the terminal can acquire ephemeris information, receive the accessible wave position changing signaling notified by the network side, and switch to a new service wave beam at a corresponding moment according to the changing start time, the new service satellite type, the wave beam parameters and other information indicated in the signaling.

Because the wave position of the service terminal may be changed due to the movement of the terminal or the satellite movement, the terminal may continuously monitor the network and report the status to the network device in time, including one or more of the following:

acquiring a neighbor cell or neighbor satellite or neighbor wave position list;

Performing neighbor cell, neighbor satellite or neighbor wave position measurement, measuring signals of the wave position service wave beam, measuring signals of the same attribute neighbor wave position, measuring signals of different attribute neighbor wave positions, and reporting measurement results;

And periodically or aperiodically reporting the information such as the position, the motion state and the like of the terminal.

The network device may also receive information reported by the terminal, where the information includes one or more of the following:

The terminal measures the adjacent wave position with the same attribute;

The location of the terminal;

and the motion state of the terminal.

Wherein, the 'same-attribute adjacent wave position' refers to adjacent wave positions corresponding to satellites of the same type; the "different-attribute adjacent wave position" refers to adjacent wave positions corresponding to different types of satellites.

After obtaining the information, the network device may make adjustments to the accessible wave-level list, etc.

In the embodiment of the application, the network equipment forms a plurality of independent wave positions on the ground, and then the network equipment configures different accessible wave positions for satellites of different orbit types, so that the hopping beams of the satellites of different orbit forming the plurality of independent wave positions only serve the accessible wave positions for communication. By the mode, on one hand, communication resources of satellites in each layer can be fully utilized, satellites in overlapping coverage areas of different orbit layers do not need to be closed, and the system capacity can be maximized; on the other hand, the same-frequency interference between the same-orbit satellite and satellites of different orbit layers can be effectively avoided by the way that the wave position is isolated in space and the satellite wave beam is in time-sharing jump on the accessible wave position.

As can be seen from the above description, for the heterogeneous hybrid satellite constellation beam hopping communication system, the embodiment of the application adopts the multi-layer heterogeneous hybrid constellation which works in the same frequency multiplexing way by configuring the ground wave position and configuring different accessible wave positions for satellites of different orbit types, and accesses different wave positions for satellites of different orbit types in the overlapping coverage area of the multi-layer orbit, so that the resource utilization rate of the whole system can be improved, and the same-frequency interference between satellites of different orbit layers can be effectively avoided through wave position configuration and beam hopping.

In the above embodiments, the two-layer track is described as the polar track and the inclined track, respectively. The method of embodiments of the present application may also be applied to other satellite systems, such as high-orbit, synchronous-orbit, and high-low orbit hybrid types of heterogeneous satellite systems.

Referring to fig. 5, fig. 5 is a flowchart of a communication method provided in an embodiment of the present application, as shown in fig. 5, including the following steps:

step 501, the satellite base station receives the wave bit access information sent by the network device.

Step 502, the satellite base station determines accessible wave positions according to the wave position access information.

Wherein the wave bit access information includes:

time information for representing effective time information of the wave bits; the wave bit identifier is used for uniquely identifying the wave bit; the type of satellite that can be accessed is used to represent the type of satellite that can access the wave position.

In this step, the satellite base station queries the wave position access information according to the current time information and the target satellite type of the satellite base station, determines a target wave position identifier matched with the current time information and the target satellite type, and determines an accessible wave position according to the target wave position identifier.

When the wave position access information is updated, the satellite base station can also receive the updated wave position access information sent by the network equipment, so that the satellite base station can accurately determine the wave position.
