Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a satellite-ground base station frequency sharing method, device, equipment and medium. Background Art

[0002] At present, there is a huge difference between the coverage area of ​​satellite cells and ground cells. A satellite beam can reach more than 1,000 square kilometers, while the coverage area of ​​ground cells is much smaller than that of satellite beams. Therefore, when the satellite network and the ground network are jointly networked, there may be a large number of ground network cells in the overlapping area of ​​the satellite network and the ground network. At present, the satellite network and the ground network are independent of each other. In order to avoid co-frequency interference between the satellite and the ground, as long as there is an overlapping coverage area between the satellite and the ground, the satellite cell cannot fully utilize the ground network frequency, resulting in the inability to achieve efficient satellite-ground frequency sharing.

[0164] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0165] For ease of understanding, some contents involved in the embodiments of the present invention are described below:

[0166] At present, there is a huge difference between the coverage area of ​​satellite cells and ground cells. A satellite beam can reach more than 1,000 square kilometers. Assuming that the satellite has 100 wave positions, the coverage area of ​​the satellite corresponding cell can reach more than 100,000 square kilometers. Assuming that the coverage radius of the ground cell is 2 kilometers, the coverage area is 15 square kilometers, which is much smaller than the coverage area of ​​the satellite beam. Therefore, when the satellite network and the ground network are jointly networked, there may be a large number of ground network cells in the overlapping area of ​​the satellite network and the ground network. How to effectively sort out the relationship between satellite cells and ground cells in the overlapping coverage area of ​​satellite and ground, and realize efficient sharing of satellite and ground frequencies has become an urgent problem to be solved.

[0167] For example, Figure 1 Schematic diagram of a satellite wide-area coverage method provided by an embodiment of the present invention. Figure 1As shown, there are satellite-ground overlapping areas in the satellite's wave positions 3, 6, and 7. How to accurately associate the wave positions in the satellite cell with the ground stations in the overlapping areas has become an urgent problem to be solved. From the perspective of satellite-ground frequency sharing, in the overlapping areas between the satellite and the ground, such as wave positions 6 and 7, the ground base stations corresponding to wave positions 6 and 7 use f1 and f2 frequencies. If refined management is not considered and only simple satellite-ground frequency sharing is considered, then f1 and f2 frequencies will not be used in this satellite cell. But in fact, wave positions 1, 2, 4, 5, and 8 have no satellite-ground overlapping areas. Ground frequencies f1 and f2 can be used freely in these wave positions, while wave positions 3, 6, and 7 have satellite-ground overlapping areas. Wave positions 3 and 7 can use f2 frequency, and wave position 6 can use f1 frequency. Therefore, how to achieve efficient satellite-ground frequency sharing has become a key issue.

[0168] In the embodiments of the present invention, a satellite-ground base station frequency sharing method, device, equipment and medium are proposed to solve the problem that the prior art cannot achieve efficient satellite-ground frequency sharing.

[0169] See also Figure 2 , Figure 2 This is one of the flow charts of a satellite-ground base station frequency sharing method provided by an embodiment of the present invention, which is applied to a satellite base station, such as Figure 2 As shown, the method comprises the following steps:

[0170] Step 201: Receive at least one first ground base station information corresponding to the satellite base station sent by the satellite-ground collaboration gateway, wherein the first ground base station information includes a wave position association relationship between the satellite base station and the first ground base station, and a first operating frequency of the first ground base station, and the wave position association relationship is used to indicate an overlap between at least one wave position group or wave position of the satellite base station and a signal coverage range of the first ground base station.

[0171] It should be understood that the satellite-ground collaboration gateway may be used to receive information of ground base stations, organize it, and send it to the corresponding satellite base station. The at least one first ground base station corresponding to the at least one first ground base station information may include all ground base stations that overlap with the signal coverage range of the satellite base station. The first operating frequency may be the wireless frequency range occupied by the first ground base station. The at least one wave position group or wave position may include at least one wave position of the satellite base station. The wave position association relationship may include specific wave position group or wave position information in the satellite base station that overlaps with the signal coverage range of the first ground base station.

[0172] For example, Figure 3 is a schematic diagram of interaction between a satellite-ground collaboration gateway and a satellite-ground collaboration node provided by an embodiment of the present invention, such as Figure 3As shown, the satellite-ground collaboration gateway initiates information push to the satellite-ground operation node. The push information may include a list of ground base station information in the satellite-ground overlap area. Each ground base station information includes the corresponding ground base station ID, working frequency band, one or more of the associated satellite cell wave position information, etc. After receiving the push information, the satellite-ground collaboration node feeds back the push result to the satellite-ground collaboration gateway.

[0173] Specifically, the satellite-ground cooperation node is used as a part of the satellite base station to receive push information sent by the satellite-ground cooperation gateway. The ground base station information list includes all ground base stations that have overlapping areas with the satellite base station, the ground base station ID is the identification information of the ground base station, the working frequency band is the working frequency of the ground base station, and one or more of the associated satellite cell wave position information is the wave position association relationship, including specific wave position information of the overlapping area with the ground base station, wherein a satellite base station may include multiple satellite cells, and a satellite cell may include multiple wave positions.

[0174] Step 202: Determine a third operating frequency corresponding to the at least one beam position group or beam position according to the beam position association relationship, the first operating frequency and the second operating frequency of the satellite base station.

[0175] It should be understood that the second operating frequency may be a wireless frequency range occupied by the satellite base station. The third operating frequency corresponding to the at least one beam position group or beam position is used to indicate the frequency that the satellite base station can use for service scheduling in the at least one beam position group or beam position, wherein each beam position group or beam position corresponds to a third operating frequency.

[0176] Specifically, based on the wave position association relationship, it can be determined whether each wave position group or wave position has a signal coverage range that overlaps with the first ground base station, and then the third operating frequency corresponding to the at least one wave position group or wave position is determined based on the first operating frequency and the second operating frequency.

[0177] Step 203: Use a third working frequency corresponding to a first beam bit group or beam bit to perform service scheduling for a terminal corresponding to the first beam bit group or beam bit, where the first beam bit group or beam bit is any beam bit group or beam bit of the at least one beam bit group or beam bit.

[0178] Specifically, the service scheduling may include sending a broadcast message to a terminal and managing and allocating wireless resources, and the terminal corresponding to the first waveband group or waveband may refer to the terminal being located in a signal coverage range corresponding to the first waveband group or waveband.

[0179] In an embodiment of the present invention, the above-mentioned satellite-to-ground base station frequency sharing method is applied to a satellite base station. By receiving at least one first ground base station information corresponding to the satellite base station sent by the satellite-to-ground cooperation gateway, the satellite base station can determine the specific frequency overlap of the satellite base station's wave position group or wave position with the at least one first ground base station based on the ground base station information sent by the satellite-to-ground cooperation gateway, and then determine the frequency of the satellite base station for service scheduling at different wave position groups or wave positions, so that the satellite base station can make full use of the frequency of the ground base station to achieve efficient satellite-to-ground base station frequency sharing.

[0180] Optionally, determining, according to the beam position association relationship, the first operating frequency, and the second operating frequency of the satellite base station, respectively, a third operating frequency corresponding to the at least one beam position group or beam position includes:

[0181] Determine, according to the beam position association relationship, the first operating frequency and the second operating frequency of the satellite base station, an overlapping frequency of the second operating frequency of the satellite base station in the at least one beam position group or beam position and the first operating frequency;

[0182] According to the overlapping frequency corresponding to the at least one beam position group or beam position and the second operating frequency, a third operating frequency corresponding to the at least one beam position group or beam position is determined respectively, and the third operating frequency is a frequency other than the overlapping frequency in the second operating frequency.

[0183] Specifically, a specific wave position group or wave position overlapping with the signal coverage range of the first ground base station can be determined according to the wave position association relationship, and then an overlapping frequency of the satellite base station in the overlapping specific wave position group is determined according to the first working frequency and the second working frequency of the satellite base station. The satellite base station will not schedule the overlapping frequency corresponding to the at least one wave position group within the at least one wave position group.

[0184] For example, the signal coverage range of the satellite base station's wave position 1 overlaps with that of the ground base station. Figure 4 is a schematic diagram of frequency overlap provided by an embodiment of the present invention, such as Figure 4 As shown, there is frequency overlap between wave position 1 and the ground base station, that is, there is overlap between the f1-f4 frequencies, so the satellite base station will not schedule the frequency range of f1-f4 in wave position 1. The f1-f4 frequencies are the overlapping frequencies of wave position 1. Assuming that the second operating frequency of the satellite base station is the f1-f8 frequency, the third operating frequency corresponding to wave position 1 is the f5-f8 frequency.

[0185] In an embodiment of the present invention, the above-mentioned satellite-to-ground base station frequency sharing method is applied to a satellite base station. According to the wave position association relationship, the first operating frequency and the second operating frequency of the satellite base station, the overlapping frequency of the second operating frequency of the satellite base station in at least one wave position group or wave position and the first operating frequency can be determined, and then the third operating frequency corresponding to the at least one wave position group or wave position can be determined, so that the satellite base station does not schedule the overlapping frequency in the corresponding wave position group or wave position, thereby avoiding interference with the terminal reception signal in the wave position group or wave position, thereby improving the communication quality of the terminal.

[0186] Optionally, the method further includes:

[0187] Determine, according to the first operating frequency and the second operating frequency, first shared frequencies of the first ground base station and the satellite base station, respectively, where the first shared frequency includes the first operating frequency and the second operating frequency;

[0188] Determine, according to the beam position association relationship, the first shared frequency, and the frequency usage of the first ground base station, respectively, a second shared frequency corresponding to the at least one beam position group or beam position, wherein the second shared frequency is a frequency of the first ground base station in the first shared frequency other than the usage frequency of the at least one beam position group or beam position;

[0189] A broadcast message is sent to a terminal corresponding to the first wave position group or wave position, wherein the broadcast message includes dedicated frequency broadcast information, the dedicated frequency broadcast information includes uplink reinforced frequency band information or downlink reinforced frequency band information corresponding to the first wave position group or wave position, and the uplink reinforced frequency band information or downlink reinforced frequency band information includes a second shared frequency corresponding to the first wave position group or wave position.

[0190] It should be understood that the first shared frequency can be understood as the union of the working frequencies of the first ground base station and the satellite base station. Since the first ground base station may not use some working frequencies in some wave positions or wave positions, the second shared frequency can be a frequency in the first shared frequency other than the frequency used by the first ground base station. The satellite base station can eliminate the shared frequencies used by the ground base station according to the frequency usage of the ground base station in a specific wave position or wave position group, and the remaining shared frequencies can be used for uplink reinforcement (Supplementary uplink, SUL) or downlink reinforcement.

[0191] For example, the satellite base station can distinguish the cell frequency band information in the broadcast message, which is divided into two parts, one part is for the cell public broadcast information, and the other part is for the dedicated frequency broadcast information corresponding to the wave position or wave position group. For example, the SUL frequency band can introduce a special definition for the wave position or wave position group in the system information block (SIB) broadcast message, that is, each wave position / wave position group has its own SUL frequency band definition. The specific code is as follows:

[0192] supplementaryUplink UplinkConfigCommonSIB OPTIONAL,--Need R

[0193] Among them, supplementaryUplink indicates the supplementary uplink frequency band configuration.

[0194] In an embodiment of the present invention, the above-mentioned satellite-to-ground base station frequency sharing method is applied to a satellite base station. The first shared frequencies of the first ground base station and the satellite base station can be determined respectively according to the first working frequency and the second working frequency, and the second shared frequencies corresponding to the at least one wave position group or wave position can be determined respectively according to the wave position association relationship, the first shared frequency and the frequency usage of the first ground base station. The second shared frequency can be used for uplink reinforcement or downlink reinforcement, thereby improving the uplink efficiency or downlink efficiency of the satellite base station, thereby improving the communication quality with the terminal.

[0195] Optionally, the method further includes:

[0196] Determine, according to the first operating frequency and the second operating frequency, first shared frequencies of the first ground base station and the satellite base station, respectively, where the first shared frequency includes the first operating frequency and the second operating frequency;

[0197] Determine, according to the beam position association relationship, the first shared frequency, and the frequency usage of the first ground base station, respectively, a second shared frequency corresponding to the at least one beam position group or beam position, wherein the second shared frequency is a frequency of the first ground base station in the first shared frequency other than the usage frequency of the at least one beam position group or beam position;

[0198] The second shared frequency corresponding to the first waveband group or waveband is used to provide a carrier aggregation service for a terminal corresponding to the first waveband group or waveband.

[0199] Specifically, the satellite base station can remove the frequency used by the ground base station according to the frequency used by the ground base station in the specific wave group or wave, and the remaining shared frequency can be used for carrier aggregation. The satellite base station can be configured according to the terminal reporting capability, and perform carrier aggregation configuration, activation and deactivation for the terminal in the specific wave group or wave.

[0200] In an embodiment of the present invention, the above-mentioned satellite-to-ground base station frequency sharing method is applied to a satellite base station, and can determine the first shared frequencies of the first ground base station and the satellite base station respectively according to the first working frequency and the second working frequency, and determine the second shared frequency corresponding to the at least one wave position group or wave position respectively according to the wave position association relationship, the first shared frequency and the frequency usage of the first ground base station, and then use the second shared frequency to provide carrier aggregation services for the terminal, thereby improving the signal transmission rate and system capacity.

[0201] Optionally, the first ground base station information further includes identification information of the first ground base station, and the method further includes:

[0202] Sending a connection establishment message to the first ground base station according to the identification information in the first ground base station information;

[0203] Receive a connection establishment feedback message sent by the first ground base station in response to the connection establishment message.

[0204] Specifically, the identification information may be a unique identification code of the first ground base station, and the connection establishment feedback message may be used to indicate whether the connection is successful.

[0205] For example, Figure 5 FIG. 1 is a schematic diagram of interaction between a satellite-ground cooperation node and a ground base station provided by an embodiment of the present invention. Figure 5 As shown, the satellite-ground cooperation node first initiates a connection establishment process to the ground base station to establish a satellite-ground base station association relationship; the ground base station feeds back the connection establishment result to the satellite-ground cooperation node. The satellite-ground cooperation node, as a part of the satellite base station, is used to establish a connection with the ground base station.

[0206] It should be noted that after the satellite base station and the ground base station establish a connection, they can send and receive information to each other according to specific needs. The information may include their own load information, which can be used to allocate wireless resources and achieve load balancing.

[0207] In an embodiment of the present invention, the above-mentioned satellite-to-ground base station frequency sharing method is applied to a satellite base station. According to the identification information in the first ground base station information, a connection establishment message can be sent to the first ground base station, and a connection establishment feedback message sent by the first ground base station can be received to complete the connection with the first ground base station. Then, load information can be sent and received to each other according to specific needs, resources can be allocated, and load balancing can be achieved.

[0208] See also Figure 6 , Figure 6 This is a second flow chart of a satellite-ground base station frequency sharing method provided by an embodiment of the present invention, which is applied to a ground base station, such as Figure 6 As shown, the method comprises the following steps:

[0209] Step 601: Send a registration message to the satellite-ground collaboration gateway, where the registration message includes identification information, overlapping information and a first operating frequency of the ground base station, where the overlapping information includes at least one satellite cell information and at least one wave position information overlapping with the signal coverage range of the ground base station.

[0210] Specifically, the identification information may be a unique identification code of the first ground base station, and the first operating frequency may be a wireless frequency range occupied by the ground base station.

[0211] It should be noted that the overlapping information may include information of multiple satellite cells overlapping with the signal coverage of the ground base station, as well as specific overlapping wave position information.

[0212] Step 602: Receive a registration feedback message from the satellite-ground collaboration gateway in response to the registration message.

[0213] Specifically, the registration feedback message may be used to indicate whether the satellite-ground collaboration gateway has completed the registration of the ground base station.

[0214] For example, Figure 7 FIG. 1 is one of the schematic diagrams of interaction between a satellite-ground collaboration gateway and a ground base station provided in an embodiment of the present invention. Figure 7 As shown, first, the ground base station initiates registration with the satellite-ground collaborative gateway. The registration information includes base station information, which may specifically include the ground base station ID, the ground base station operating frequency and other information, as well as the overlapping satellite cell information and wave position information in the area where the ground base station is located, where the satellite cell and wave position information can be one or more; then the registration result fed back by the satellite-ground collaborative gateway is received.

[0219] Specifically, the change information may include changes in the first operating frequency of the ground base station, and may also include changes in overlapping information between the ground base station and the satellite base station, for example, changes in specific overlapping wave positions.

[0220] For example, Figure 8 FIG. 2 is a second schematic diagram of interaction between a satellite-ground collaboration gateway and a ground base station provided in an embodiment of the present invention. Figure 8 As shown, first, the ground base station initiates an update to the satellite-ground collaborative gateway. The update information includes the base station ID information and one or more change information in the base station information. It may also include the overlapping satellite cell information and wave position information in the area where the base station is located, where the satellite cell and wave position information can be one or more; finally, the update result fed back by the satellite-ground collaborative gateway is received.

Fig. 9 As shown, first, the ground base station initiates a deregistration request to the satellite-ground collaboration gateway. The deregistration message must include the base station ID information, and then receives the deregistration result fed back by the satellite-ground collaboration gateway.

[0226] In an embodiment of the present invention, the above-mentioned satellite-ground base station frequency sharing method is applied to a ground base station, and a deregistration message can be sent to the satellite-ground cooperation gateway, and the deregistration message is used to request deregistration of the ground base station, so that the ground base station can request deregistration from the satellite-ground cooperation gateway when there is no overlap, and then the satellite-ground cooperation gateway can clear the corresponding ground base station information in time, thereby further improving the accuracy of satellite-ground base station frequency sharing.
