Example 1
Fig. 1 is a flowchart of a connection request-based method for establishing a fixed cell according to an embodiment of the present application. As shown in fig. 1, the method specifically comprises the following steps:
s101, receiving a network connection request of ground terminal equipment; the network connection request comprises the position information of the ground terminal equipment and network demand information;
the application scenario of the scheme may be a scenario in which when the ground terminal device communicates through a non-ground network, the satellite analyzes a network connection request type of the ground terminal device, and establishes a fixed cell under the condition that the request type is a preset type, so as to provide a continuous and stable communication channel for the ground terminal device.
Based on the above usage scenario, it can be appreciated that the execution subject of the present application may be the satellite, or may be a control system of the satellite, a satellite server, etc., which is not limited herein.
The ground terminal device may be a ground terminal device that inputs programs and data to a computer via a communication facility or receives a result of processing output from the computer. The ground terminal device has the capabilities of receiving and transmitting information, transmitting data, calculating and the like, and for example, a desktop computer, a notebook computer, a mobile phone, a tablet computer, an interactive multimedia device and the like can be used as the ground terminal device.
The network connection request may be a request instruction for connecting to the non-terrestrial network sent to the satellite before the terrestrial terminal device needs to communicate through the non-terrestrial network, so as to obtain a communication channel of the non-terrestrial network. After receiving the network connection request, the satellite can allocate beams to the position of the ground terminal equipment according to the request content to establish a fixed cell for the ground terminal equipment to communicate. The network connection request may include location information of the ground terminal device, network demand information, and the like. The location information of the ground terminal equipment can be represented by longitude and latitude coordinate values so as to determine the establishment location of the fixed cell. The network demand information can be related information such as network connection request type of the ground terminal equipment, estimated communication duration and the like.
S102, identifying the request type of the network connection request according to the network demand information;
the method for identifying the request type of the network connection request may be to determine the request type of the network connection request according to the urgency of the network connection request information and the predicted communication duration. For example, if the request type is to seek help, emergency rescue, etc., the degree of urgency is high and a longer communication connection needs to be maintained to obtain more important information; if the request type is common communication, information transmission, etc., and the time efficiency requirement is low, the communication can be performed without adopting a fixed cell, so as to avoid occupying the channel of the emergency communication and affecting the transmission time of the emergency communication information.
S103, if the request type is a preset type, generating an instruction for establishing a fixed cell for the ground terminal equipment;
the preset type may be a preset request type requiring wireless communication through a fixed cell. The preset type requires a longer communication connection duration and a shorter information delay time, so that a stable information transmission path needs to be established by the fixed cell to avoid that frequent satellite and beam switching affects the timeliness of communication.
The method for generating the instruction for establishing the fixed cell for the ground terminal equipment can be that after the request type is identified to be consistent with the preset type, the satellite writes the establishment position of the fixed cell, the quantity of the ground terminal equipment in the fixed cell, the communication requirement and other information into the instruction for establishing the fixed cell for the ground terminal equipment, and inserts the identification of the establishment condition of the fixed cell and the result feedback instruction into the appointed position in the instruction, and sends the instruction to the beam transmitting functional module of the low orbit satellite so as to control the functional module to establish the fixed cell for the ground terminal equipment according to the instruction content.
S104, identifying whether the local area has the establishment capability of the fixed cell;
locally, it may refer to a low orbit satellite providing a communication beam for the current ground terminal device. The fixed cell, which may be a region providing wireless communication services to users, is a basic constituent unit of a wireless network. The relative position of the fixed cell and the ground terminal equipment does not change along with the movement of the satellite, so that the ground terminal equipment in the fixed cell can be provided with a long-time continuous communication connection duration.
The method for identifying whether the local has the establishment capability of the fixed cell can be that after the satellite receives the instruction for establishing the fixed cell for the ground terminal equipment, the establishment position of the fixed cell is determined according to the position of the ground terminal equipment in the network connection request, the path of a beam transmitted by the satellite to the fixed cell and the change range of the beam path along with the movement of the satellite when the satellite moves along the track are determined according to the relative position of the fixed cell and the low orbit satellite, whether the beam generated by the satellite can reach the position of the fixed cell at each moment in the change range is identified, the communication quality of the beam reaching the position of the fixed cell is predicted, and if the beam in the change range can reach the position of the fixed cell and the communication quality of the beam meets the communication requirement of the ground terminal equipment, the local has the establishment capability of the fixed cell.
And S105, if the fixed cell establishment capability is provided, establishing the fixed cell for the ground terminal equipment based on the position information.
The method for establishing the fixed cell can be that after the satellite recognizes that the satellite has the local establishment capability of the fixed cell, the satellite predicts the position change of the satellite relative to the fixed cell in the process of moving from the current position to the outside of the connection range with the fixed cell along the motion track, the azimuth change process of the satellite transmitting wave beam is obtained according to the change condition of the relative position, the quantity of wave beams required by the ground terminal equipment in the current fixed cell range is predicted, and the satellite transmits the wave beams to the position of the fixed cell according to the predicted quantity and the azimuth change condition so as to establish the fixed playing cell.
In the embodiment of the application, a network connection request of ground terminal equipment is received; the network connection request comprises the position information of the ground terminal equipment and network demand information; identifying a request type of the network connection request according to the network demand information; if the request type is a preset type, generating an instruction for establishing a fixed cell for the ground terminal equipment; identifying whether the local has the establishment capability of a fixed cell; and if so, establishing a fixed cell for the ground terminal equipment based on the position information. By the method for establishing the fixed cell based on the connection request, the fixed cell can be established for the ground terminal equipment according to the network connection request, the situations of information transmission delay and the like caused by frequent cell switching are avoided, stable network signals are provided for users, and the continuity and timeliness of communication are ensured.
Example two
Fig. 2 is a flow chart of a connection request-based method for establishing a fixed cell according to a second embodiment of the present application. The scheme makes better improvement on the embodiment, and the specific improvement is as follows: after identifying whether the local has the setup capability of the fixed cell, the method further comprises: if not, generating a fixed cell establishment request according to the position information of the ground terminal equipment; sending the fixed cell establishment request to a candidate satellite with the current signal covered to the position information, and acquiring establishment capability feedback data fed back by the candidate satellite; and determining a target satellite according to the establishment capability feedback data, and establishing a fixed cell for the ground terminal equipment through the target satellite.
As shown in fig. 2, the method specifically includes the following steps:
s201, receiving a network connection request of ground terminal equipment; the network connection request comprises the position information of the ground terminal equipment and network demand information;
s202, identifying the request type of the network connection request according to the network demand information;
s203, if the request type is a preset type, generating an instruction of the ground terminal equipment;
s204, identifying whether the local area has the establishment capability of the fixed cell; if yes, executing S205; if not, executing S206;
s205, establishing a fixed cell for the ground terminal equipment based on the position information;
s206, generating a fixed cell establishment request according to the position information of the ground terminal equipment;
the method for generating the fixed cell establishment request may be that after recognizing that the local has no establishment capability of the fixed cell, the fixed cell establishment request is generated to request feedback data of other low-orbit satellite feedback establishment capability and prepare to establish the fixed cell for the ground terminal device. The fixed cell establishment request includes location information of the ground terminal device, so that other low-orbit satellites can conveniently determine whether the ground terminal device is within the coverage range of each signal.
S207, sending the fixed cell establishment request to a candidate satellite with the current signal covering the position information, and acquiring establishment capability feedback data fed back by the candidate satellite;
the candidate satellite may be a satellite where the signal can cover the location of the ground terminal device, i.e. the beam emitted by the satellite may enable the ground terminal device to continuously make a communication connection with the satellite during the satellite's orbital movement.
The method for obtaining the establishment capability feedback data of the candidate satellite feedback may be that each satellite recognizes its own signal coverage, and screens out satellites whose signals can completely cover the area where the fixed cell is located as candidate satellites. After determining candidate satellites, each candidate satellite predicts the running track of the candidate satellite, calculates whether the connection with the fixed cell can be continuously maintained in the running process and the communication quality in the connection process, and takes the calculation result as the establishment capability feedback data of the current candidate satellite.
In the embodiment of the application, the relative position of the satellite and the fixed cell changes along the track moving process. Therefore, it is necessary to change the angle of beam transmission according to the relative position change of the satellite and the fixed cell, or to perform beam switching to achieve continuous connection with the fixed cell. The satellite which can make the wave beam always reach the position of the fixed cell by changing the wave beam transmitting angle or switching the wave beam and the like in the running process has the establishment capability of the fixed cell.
And S208, determining a target satellite according to the establishment capability feedback data, and establishing a fixed cell for the ground terminal equipment through the target satellite.
The method for determining the target satellite may be that after determining the capability feedback data for establishing feedback of each candidate satellite, candidate satellites capable of continuously maintaining connection with the fixed cell in the operation process are screened out according to the capability feedback data to be used as target satellites for establishing the fixed cell for the ground terminal equipment. If a plurality of candidate satellites capable of continuously maintaining connection with the fixed cell in the operation process exist, extracting the communication quality of each candidate satellite on the basis of the candidate satellites, and selecting the candidate satellite with the best communication quality and relatively stable as the current target satellite.
The method has the advantages that the target satellite can be determined and the fixed cell can be established according to the establishment capability feedback data fed back by the candidate satellite under the condition that the local device does not have the establishment capability of the fixed cell, so that the communication channel can be ensured to be normally connected when an emergency occurs, and the timeliness of information transmission is prevented from being influenced.
Example III
Fig. 3 is a flow chart of a method for establishing a fixed cell based on a connection request according to a third embodiment of the present application. The scheme makes better improvement on the embodiment, and the specific improvement is as follows: after generating the fixed cell setup request, the method further comprises: acquiring the current time; determining elevation angle data of each satellite according to the pre-stored ephemeris information and the current time; and determining a target satellite according to the establishment capability feedback data and the elevation angle data, and establishing a fixed cell for the ground terminal equipment through the target satellite.
As shown in fig. 3, the method specifically includes the following steps:
s301, receiving a network connection request of ground terminal equipment; the network connection request comprises the position information of the ground terminal equipment and network demand information;
s302, identifying the request type of the network connection request according to the network demand information;
s303, if the request type is a preset type, generating an instruction of the ground terminal equipment;

the mode of acquiring the current time can be that the satellite acquires world standard time of the current moment through big data. The world standard time may be a time measurement system which is as close to the world time as possible in time on the basis of atomic time seconds.
S309, determining elevation angle data of each satellite according to the pre-stored ephemeris information and the current time;
ephemeris information, which may be an expression for describing the position and speed of a space vehicle, can accurately calculate and predict the operation states such as the position, speed, etc. of a tracking satellite and a vehicle, and can express accurate parameters of a vehicle such as a celestial body, a satellite, a spacecraft, a missile or space debris, etc., and describe the past, present and future of the celestial body with time and three dimensions.
The elevation data of the satellite may be the angle between the line of sight of the earth's surface terminal equipment located on the earth to the satellite and the local horizon at a given moment. For example, when the satellite passes directly above the ground terminal equipment at a certain moment, the elevation angle data of the satellite is 90 degrees. The larger the elevation angle data of the satellite is, the higher the coverage rate of the satellite to the position of the fixed cell is, and the better the communication quality is.
The method for determining the elevation data of the satellite can be that a large number of different time points, ephemeris information and corresponding satellite elevation data are obtained through big data, the elevation data are used as labels, the ephemeris information and each time point are used as input variables, and supervision training is carried out to obtain the elevation data of the satellite corresponding to each time point under the ephemeris information, so that a big data model capable of calculating the elevation data of the satellite according to the ephemeris information and the current time is constructed. And inputting the currently acquired time data and the pre-stored ephemeris information into a pre-constructed big data model, and feeding back the elevation angle data of the satellite corresponding to the current time by the big data model according to the learning result of the ephemeris information.
