Background
With the continuous development of wireless communication networks, the coverage area thereof is wider and wider, but the wide coverage of the wireless communication networks means higher network construction cost and maintenance cost. Therefore, for remote mountainous areas, uninhabited desert areas, and the like, operators generally do not establish ground base stations of wireless communication networks, but tend to employ satellites for network coverage.

However, a large number of common terminals do not have such capability, and cannot directly communicate with the satellite, so that the terminals cannot transmit data through the satellite.

According to some embodiments of the present application, a method for satellite-based connection establishment is disclosed. The main execution body of the satellite-based connection establishment method in this embodiment is a backpack base station. Referring to fig. 1, fig. 1 is a flow chart illustrating a method for establishing a satellite-based connection according to some embodiments of the present application.
As shown in fig. 1, the satellite-based connection establishment method may be as follows.
In step S101, the first satellite transmits a wireless signal.
The first satellite transmits a wireless signal through a broadcast channel. The wireless signal carries a plurality of preset time points. Each of the predetermined plurality of time points is a time point at which the first satellite desires to receive the first random access request. The first random access request includes a random access preamble.
Step S102, the backpack base station determines a first time point according to the received wireless signal.
The backpack base station receives a wireless signal sent by the first satellite, analyzes the wireless signal to obtain a plurality of preset time points, and selects a first time point from the plurality of preset time points as a time point for the first satellite to receive the first random access request.
For example, the backpack base station selects a first time point from the analyzed preset time points according to the current time point. For example, the backpack base station may select, from a predetermined plurality of time points, one of the time points that is greater than or equal to a first predetermined time period before the current time point and is closest to the current time point as the first time point, so that the first satellite can receive the first random access request at the first time point.
The first predetermined time period is determined according to the maximum distance of the coverage area of the first satellite signal, for example, the first predetermined time period is 0.5 seconds (this is for example) obtained by dividing the maximum distance of the coverage area of the first satellite signal by the speed of light. Assuming that the preset plurality of time points are 12 points 5 minutes 30 seconds, 12 points 5 minutes 35 seconds, 12 points 5 minutes 40 seconds, 12 points 5 minutes 45 seconds and the like, no further enumeration is made, and the current time point is 12 points 5 minutes 38 seconds. Among all the time points, 12 points, 5 minutes and 35 seconds are one time point which is more than or equal to 0.5 second from the current time point and is closest to the current time point, so 12 points, 5 minutes and 35 seconds are taken as the first time point.
Step S103, the backpack base station acquires a first position of the backpack base station.
The first location may include longitude information and latitude information of the backpack base station; alternatively, the first location information may include Global Positioning System (GPS) coordinates of the backpack base station, and longitude information and latitude information of the backpack base station are calculated from the GPS coordinates.
The backpack base station may obtain the first position of the backpack base station through any one of a positioning device or configuration information, specifically:
for example, the backpack base station obtains the current position of the backpack base station through a built-in positioning device, and determines the current position as the first position.
Or, the backpack base station determines the first position according to the received first position configuration information. For example, the backpack base station receives first location configuration information input by a user, and determines a first location according to the first location configuration information.
Step S104, the backpack base station acquires the second position of the first satellite. The second position comprises the geometric position of the first satellite on the celestial sphere, longitude information and latitude information of the geometric position on a ground projection point, the height of the first satellite from the ground, and the like.
In this step, the backpack base station may obtain the second position through the configuration information; or, the backpack base station may obtain the second position through a corresponding relationship between the moving track of the first satellite and the time point, which is not specifically limited in this embodiment.
Specifically, when the second location is obtained through the configuration information, the backpack base station may obtain the second location configuration information from the core network device, and analyze the obtained second location configuration information to obtain the second location; or, the backpack base station may obtain the second location configuration information from the memory, and analyze the second location configuration information to obtain the second location.
When the second position is obtained through the corresponding relation between the running track of the first satellite and the time point, the backpack base station obtains the corresponding relation between the running track of the first satellite and the time point from the core network equipment, and determines the second position according to the current time point and the corresponding relation between the running track and the time point; or, the backpack base station may obtain the corresponding relationship between the operation trajectory of the first satellite and the time point from the memory, and determine the second position according to the current time point and the corresponding relationship between the operation trajectory and the time point.
It should be noted that, in practical applications, the execution order of step S102, step S103, and step S104 is not limited.
Step S105, the backpack base station determines a second time point for sending the first random access request to the first satellite according to the first position, the second position and the first time point.
In this step, when determining the second time point, the backpack base station may first determine a distance between the backpack base station and the first satellite according to the first position and the second position; determining the data transmission time length between the backpack base station and the first satellite according to the distance between the backpack base station and the first satellite; and then determining a second time point according to the transmission time length and the first time point.
Specifically, the backpack base station can calculate the distance between the backpack base station and the first satellite according to the longitude information and the latitude information of the backpack base station, the longitude information and the latitude information of the first satellite at the ground projection point, the height of the first satellite from the ground and the radius of the earth.
After the distance between the backpack base station and the first satellite is determined, the data transmission duration between the backpack base station and the first satellite is determined according to the distance between the backpack base station and the first satellite, for example, the data transmission duration between the backpack base station and the first satellite is obtained by dividing the distance between the backpack base station and the first satellite by the light speed, and is X seconds.
After the data transmission duration between the backpack base station and the first satellite is obtained, a second time point for sending the first random access request to the first satellite is determined according to the data transmission duration and the first time point. Since the time point when the first satellite receives the first random access request is the first time point, the data transmission duration is required for data transmission between the backpack base station and the first satellite. Therefore, the second time point of sending the first random access request to the first satellite by the backpack base station should be the time point of X seconds before the first time point, for example, the first time point is 12 points 5 minutes 30 seconds, X seconds is 0.3 seconds, and the second time point is 0.3 seconds before 12 points 5 minutes 30 seconds, that is, 12 points 5 minutes 29.7 seconds.
Step S106, the backpack base station sends the first random access request to the first satellite at the second time point. The backpack base station may transmit a first random access request to the first satellite via a wireless signal.
Step S107, after receiving the first random access request, the first satellite transmits a first random access response. The first satellite may transmit the first random access response via a wireless signal.
Step S108, after receiving the first random access response sent by the first satellite, the backpack base station sends a first non-guaranteed NG interface establishment request (NG setup request) to the core network device through the first satellite.
In another alternative embodiment, the first non-guaranteed NG interface establishment request may contain not only the sequence for requesting establishment of the NG interface, but also the first location of the backpack base station, such as longitude information, latitude information, and the like. Step S109, after receiving the first NG interface establishment request, the core network device sends a first NG interface establishment response.
Step S110, the backpack base station receives a first NG interface setup response (NG setup response) sent by the core network device through the first satellite.
So far, the backpack base station successfully establishes connection based on the NG interface with the core network equipment through the first satellite. In practical applications, the backpack base station sends a system message broadcast. And when the terminal is positioned in the signal coverage range of the backpack base station, receiving system message broadcast and sending a connection establishment request to the backpack base station. And the backpack base station establishes connection with the terminal according to the connection establishment request. The backpack base station forwards the uplink data sent by the terminal to the first satellite, and the uplink data are transmitted to the core network equipment through the first satellite. And the backpack base station receives downlink data sent by the first satellite and transmits the downlink data to the terminal.
It should be noted that there may be a plurality of backpack base stations, and each backpack base station implements the NG interface-based connection with the core network device through the first satellite by performing the above steps. And after the plurality of backpack base stations establish connection based on the NG interface with the core network equipment through the first satellite, the first satellite allocates different numbers (IDs) to each backpack base station, and the numbers are used for the first satellite to send information or data to the designated backpack base station according to the ID of the backpack base station.
It is worth mentioning that, under the condition that there is no communication requirement, the backpack base station may further send an NG interface deletion request to the core network device through the first satellite, so as to disconnect the connection between the backpack base station and the core network device through the first satellite. For example, in the case that the original operator base station is damaged in an accident site, such as a fire, a landslide, etc., the above steps may be performed using the backpack base station, so that the backpack base station establishes a connection based on the NG interface with the core network device through the first satellite. When the original operator base station is repaired or a new operator base station is established, the backpack base station does not need to establish connection based on the NG interface with the core network equipment through the first satellite any more, and the backpack base station sends an NG interface deleting request to the core network equipment through the first satellite.
In the technical scheme of the embodiment of the application, the backpack base station successfully establishes connection based on the NG interface with the core network device through the first satellite, so that the backpack base station is accessed to the wireless cellular network through the first satellite, the backpack base station can provide communication service for a common terminal, and the terminal can communicate and transmit data with the core network device through the backpack base station.
In some application scenarios, there is a case that the backpack base station has no data or signaling transmitted to the first satellite for a certain period of time, and in order to avoid the first satellite disconnecting from the backpack base station, after the step S110, the method further includes: when meeting the preset condition, the backpack base station transmits a heartbeat packet to the first satellite, and the heartbeat packet is used for prompting that the backpack base station is in a working state. Wherein the preset condition is configured to: no data or signaling is transmitted by the backpack base station to the first satellite for a second predetermined period of time.
Specifically, the backpack base station may start the first timer each time data or signaling is transmitted to the first satellite, and if the backpack base station does not transmit data or signaling to the first satellite from the start of the first timer to the end of the timing of the first timer, a heartbeat packet needs to be transmitted to the first satellite at this time, so as to avoid that the first satellite is disconnected from the backpack base station. Meanwhile, after transmitting the heartbeat packet, the backpack base station may start the first timer again. If the backpack base station transmits data or signaling to the first satellite before the first timer expires, the backpack base station restarts the first timer.
Correspondingly, if the first satellite does not receive the data, signaling or heartbeat packet transmitted by the backpack base station within the second preset time period, the connection with the backpack base station is disconnected.
In particular, the first satellite may maintain a second timer having a timing duration equal to a timing duration of the first timer. The first satellite can start a second timer when receiving data, signaling or heartbeat packets transmitted by the backpack base station every time, and if the data, the signaling or the heartbeat packets transmitted by the backpack base station are not received from the start of the second timer to the end of the timing of the second timer, the first satellite is disconnected from the backpack base station; otherwise, if the data, signaling or heartbeat packet transmitted by the back packet base station is received before the timing of the second timer is finished, the second timer is restarted.
According to the technical scheme of the embodiment, the heartbeat packet can be transmitted to the first satellite within the second preset time length, so that the disconnection with the first satellite when no data or signaling is transmitted is avoided.
In some embodiments, when the amount of change in the location of the backpack base station exceeds the preset distance threshold, it is necessary to re-establish a communication connection with the core network device through the first satellite, and specifically, after step S110, the method may further include:
step S201, the backpack base station acquires a third position of the backpack base station.
The backpack base station can acquire a third position of the backpack base station every third preset time; the third location of the backpack base station may also be obtained in real time. This embodiment is not particularly limited thereto.
Step S202, when the distance between the third location and the first location exceeds the preset distance threshold, the backpack base station determines a third time point for retransmitting the first random access request to the first satellite according to the third location, the second location, and the first time point.
Wherein, the preset distance threshold value can be stored in the backpack base station in advance. Specifically, the backpack base station may obtain a third position every third predetermined time period, and determine whether a distance between the third position and the first position exceeds a preset distance threshold. Or, the backpack base station may obtain the third position in real time, and determine whether the distance between the third position and the first position exceeds the preset distance threshold in real time or every fourth predetermined time.
Alternatively, in another alternative embodiment, the backpack base station receives a third location input by the user, and determines a third time point for retransmitting the first random access request to the first satellite according to the third location input by the user, the second location and the first time point.
Step S203, the backpack base station returns to execute the process of sending the first random access request to the first satellite at the third time point.
In another optional embodiment, when the backpack base station returns to perform the process of sending the first random access request to the first satellite at the third time point, the first random access request may not only contain the random access preamble, but also contain a third location of the backpack base station, such as longitude information and latitude information of the backpack base station, or may further include a relative location of the third location to the first location.
According to the technical scheme of the embodiment, when the position variation of the backpack base station exceeds the preset distance threshold, the backpack base station can establish communication connection with the core network device through the first satellite again.
In some embodiments, since the backpack base station is powered by a battery, in order to prolong the operation time of the backpack base station as much as possible, after the response is established through the first NG interface sent by the first satellite receiving core network device, the method further includes: reporting the remaining battery capacity or the remaining operating time of the backpack base station to the core network device through the first satellite, specifically:
the backpack base station sends the first battery residual capacity or the first residual working time of the backpack base station to the core network equipment through the first satellite at intervals of a preset time interval, so that the core network equipment adopts a power saving mode to transmit data with the backpack base station when judging that the first battery residual capacity or the first residual working time is smaller than a threshold value.
It is worth mentioning that the threshold is configured in the core network device. The core network equipment judges whether the received first battery residual capacity or the first residual working time length is smaller than a threshold value or not every time the first battery residual capacity or the first residual working time length sent by the backpack base station through the first satellite is received.
When the core network equipment judges that the remaining capacity of the first battery or the first remaining working time is smaller than the threshold value, a plurality of data are sent to the back packet base station through the first satellite every fifth predetermined time, and single data do not need to be sent to the back packet base station through the first satellite in real time, so that the core network equipment is in a power saving mode. It should be mentioned that the core network device may not only transmit a plurality of data to the backpack base stations whose first battery remaining capacity or first remaining operating time is less than the threshold value through the first satellite every fifth predetermined time period, but also transmit a plurality of data to other backpack base stations communicatively connected thereto through the first satellite every fifth predetermined time period, so that the core network device does not need to keep the data transmission state with each backpack base station all the time.
The backpack base station receives a plurality of data sent by the core network equipment through the first satellite every a fifth predetermined time, and does not need to respectively receive single data sent by the core network equipment through the first satellite in real time, so that the backpack base station is in a power saving mode.
Or the threshold value is configured in the backpack base station, and the backpack base station sends the second remaining battery capacity or the second remaining operating time to the core network device through the first satellite when judging that the second remaining battery capacity or the second remaining operating time of the backpack base station is less than the threshold value, so that the core network device adopts the power saving mode to transmit data with the backpack base station.
The technical scheme of the embodiment can save the electric quantity of the core network equipment and the backpack base station, and is beneficial to prolonging the working time of the core network equipment and the backpack base station.
In some embodiments, considering that the first satellite is moving and its signal coverage area changes, which may result in disconnection from the backpack base station, after S110, the method further includes:
step S301, the backpack base station acquires a signal coverage end time point of the first satellite, and acquires a fourth position of the second satellite at a preset time point before the signal coverage end time point is reached.
The backpack base station can obtain a first corresponding relation between the running track of the first satellite and the time point, and obtain the geometric position of the first satellite of each time point on the celestial sphere according to the first corresponding relation, so that the corresponding signal coverage range is determined according to the geometric position of the first satellite of each time point on the celestial sphere, and the time point of ending each signal coverage range can be further determined.
Specifically, the core network device configures and stores a first corresponding relationship between a running track of the first satellite and a time point in the backpack base station. Or the core network equipment configures a first corresponding relation between the running track of the first satellite and the time point, stores the first corresponding relation in the core network equipment, and the backpack base station acquires the first corresponding relation of the core network equipment and analyzes the first corresponding relation to obtain the geometric position of the first satellite on the celestial sphere at each time point. When the backpack base station determines the corresponding signal coverage according to the geometric position of the first satellite on the celestial sphere at each time point, specifically, the longitude information and the latitude information of the first satellite on the ground projection point and the height of the first satellite from the ground can be determined according to the geometric position, so that the signal coverage of the first satellite can be determined according to the longitude information and the latitude information of the first satellite on the ground projection point and the height of the first satellite from the ground.
After determining the signal coverage of the first satellite at each time point, the backpack base station may determine a signal coverage start time point and a signal coverage end time point for different signal coverage areas.
Step S302, the backpack base station determines a fourth time point for sending the second random access request to the second satellite according to the first position, the fourth position and the first time point.
Step S303, the backpack base station sends a second random access request to the second satellite at a fourth time point.
In step S304, the second satellite transmits a second random access response after receiving the second random access request.
Step S305, after receiving the second random access response sent by the second satellite, the backpack base station sends a second NG interface establishment request to the core network device through the second satellite.
Step S306, after receiving the second NG interface establishment request, the core network device sends a second NG interface establishment response.
Step S307, the backpack base station receives a response through the second NG interface sent by the core network device through the second satellite.
It should be noted that, when one backpack base station is simultaneously located within the signal coverage of multiple (two or more) satellites, the backpack base station may also simultaneously establish a communication connection with the core network device through multiple satellites through the above steps. Because the transmission capacity of one satellite is limited, the backpack base station can establish connection with the core network equipment through a plurality of satellites simultaneously so as to achieve the purpose of increasing the communication capacity. For example, when one backpack base station is connected to the core network device through two satellites (a third satellite and a fourth satellite), when the backpack base station needs to transmit a large amount of data, and the data amount exceeds the transmission bandwidth of the third satellite and also exceeds the transmission bandwidth of the fourth satellite, the backpack base station may transmit data through the third satellite and the fourth satellite at the same time, for example, the data is preferentially transmitted through the third satellite according to the bandwidth of the third satellite, and the remaining data is transmitted through the fourth satellite.
In this embodiment, it can be avoided that the backpack base station cannot establish a connection with the core network device through the first satellite due to the disconnection of the backpack base station during the movement of the first satellite.
According to some embodiments of the present application, a method for satellite-based connection establishment is also disclosed. The main execution body of the satellite-based connection establishment method in this embodiment is a core network device. In this embodiment, the core network device receives the remaining battery capacity or the remaining operating time of the backpack base station reported by the backpack base station through the first satellite, and transmits data with the backpack base station in the power saving mode according to the remaining battery capacity or the remaining operating time. Referring to fig. 4, fig. 4 is a flowchart illustrating a satellite-based connection establishment method according to the embodiment.
As shown in fig. 4, the satellite-based connection establishment method may be as follows.
Step S401, the core network device receives a first non-guaranteed NG interface establishment request sent by the backpack base station through a first satellite.
Step S402, the core network device sends a first NG interface establishment response to the backhaul packet base station through the first satellite.
In step S403, the core network device receives the first remaining battery capacity of the backpack base station via the first satellite.
In another alternative embodiment, the core network device receives the first remaining operating time of the backpack base station via the first satellite.
Step S404, when the core network device judges that the remaining capacity of the first battery is less than the threshold value, the core network device adopts a power saving mode to transmit data with the backpack base station.
In another optional embodiment, when the core network device determines that the first remaining operating time is less than the threshold value, the core network device transmits data with the backpack base station in a power saving mode.
Or, in another optional embodiment, the core network device receives, through the first satellite, the second remaining battery capacity or the second remaining operating time of the backpack base station, where the second remaining battery capacity or the second remaining operating time is sent by the backpack base station through the first satellite when it is determined that the second remaining battery capacity or the second remaining operating time is smaller than the threshold. And the core network equipment adopts an energy-saving mode to transmit data with the backpack base station according to the second battery residual capacity or the second residual working time.
