[0002] In existing technologies, 3GPP has proposed a non-terrestrial network (NTN) access network architecture based on transparent satellite relay, which allows satellite and terrestrial operators to deploy their own satellite networks based on this architecture. Terrestrial operators can deploy their own satellite networks by leasing bandwidth from satellite operators.

[0003] The current solution takes into account the transparent forwarding characteristics of satellite platforms. Ground operators lease fixed frequencies and bandwidth from satellite operators, statically sharing satellite bandwidth resources. However, this static resource sharing method cannot make the most efficient use of valuable air interface resources, resulting in low resource utilization. Summary of the Invention

The present invention does not limit this.

[0079] It should be noted that, in the embodiments of the present invention, the interaction interface is the interface for communication between the first baseband module and the second baseband module. The first baseband module can obtain satellite platform parameters from the second baseband module through the interaction interface. The second baseband module supports the Digital Video Broadcasting-Return Channel via Satellite / Satellite-Second Generation (DVB-RCS / S2) protocol.

[0082] It should be noted that, in the embodiments of the present invention, the satellite platform EIRP and the G / T value can be the same or different for each of the multiple beams.

[0083] It should be noted that, in the embodiments of the present invention, after the first baseband module obtains the geographical location information, coverage area information and satellite platform parameters, it can use the geographical location information, coverage area information and satellite platform parameters to determine the resource demand information.

[0084] Specifically, in embodiments of the present invention, satellite platform parameters include: satellite platform altitude, satellite beam information, effective isotropic radiated power of the satellite platform, and the ratio of receive gain to equivalent noise. The first baseband module determines resource requirement information based on geographical location information, coverage area information, and satellite platform parameters, including: determining the coverage area corresponding to each of the multiple beams generated by the satellite according to the satellite platform altitude and satellite beam information; selecting beams whose corresponding coverage areas are contained in the area represented by the coverage area information from the multiple beams to form a beam set corresponding to 3GPP NTN; obtaining 3GPP NTN bandwidth, transmit power of the 3GPP NTN converged terminal, and receive sensitivity; and based on the effective isotropic radiated power of the satellite platform, the ratio of receive gain to equivalent noise, and 3GPP NTN parameters, determining the coverage area corresponding to each of the multiple beams generated by the satellite platform; selecting beams whose corresponding coverage areas are contained in the area represented by the coverage area information to form a beam set corresponding to 3GPP NTN; obtaining 3GPP NTN bandwidth, transmit power of the 3GPP NTN converged terminal, and receive sensitivity; and determining the coverage area corresponding to each of the multiple beams, the coverage area corresponding to each of the multiple beams, and selecting beams whose ...

Determine the required number of uplink frequency points and uplink bandwidth, downlink frequency points and downlink bandwidth, and terminal uplink and downlink frequency bands for each beam in the beam set as resource requirement information.

[0085] It should be noted that, in the embodiments of the present invention, the first baseband module first determines the coverage area corresponding to each of the multiple beams generated by the satellite based on the satellite platform altitude and satellite beam information; specifically, the beam information may include the beam half-angle and beam distribution; then, from the multiple beams, the beams whose corresponding coverage area is contained in the area represented by the coverage area information are selected to obtain the beam set corresponding to 3GPP NTN. At this time, the coverage area of ​​each beam included in the beam set includes a 3GPP NTN converged terminal; then, the 3GPP NTN bandwidth, the transmit power and receive sensitivity of the 3GPP NTN converged terminal are obtained, and based on the effective omnidirectional radiated power of the satellite platform, the ratio of receive gain to equivalent noise, and the 3GPP NTN converged terminal, the 3GPP NTN converged terminal is determined.

In other words, the first baseband module can send the actual resource demand information to the second baseband module through the interaction interface, and receive the resource authorization result that matches the resource demand information, thereby realizing dynamic allocation of satellite resources, avoiding the waste caused by static leasing of satellite resources, and improving the utilization rate of satellite resources.

[0089] Specifically, in the embodiments of the present invention, the resource authorization result includes: authorized resource information, or no authorized resource information is matched; the authorized resource information includes at least: the beam identifier, uplink resource authorization list and downlink resource authorization list corresponding to each beam in the beam set corresponding to the 3GPP NTN.

[0090] It should be noted that, in the embodiments of the present invention, the authorized resource information includes authorized beam identifiers, as well as uplink resource authorization lists and downlink resource authorization lists corresponding to each beam.

[0093] Specifically, in the embodiments of the present invention, the authorized resource information is information indicating authorized bandwidth resources that match the resource demand information; after receiving the resource authorization result in response to the resource request from the second baseband module, the following steps can also be performed: if the resource authorization result includes authorized resource information, the authorized bandwidth resources are allocated in the 3GPP NTN using the authorized resource information so that the 3GPP NTN converged terminal can access the authorized bandwidth resources and realize resource sharing.

[0094] It should be noted that, in the embodiments of the present invention, after obtaining the authorized resource information, the first baseband module allocates authorized bandwidth resources in the 3GPP NTN so that the 3GPP NTN converged terminal can access the authorized bandwidth resources and realize resource sharing of satellite resources.

[0095] Specifically, in the embodiments of the present invention, the first baseband module utilizes authorized resource information to allocate authorized bandwidth resources in the 3GPP NTN, including: for each beam identifier corresponding to a beam in the beam set, determining the corresponding number of terminals to be accessed based on the corresponding coverage area and geographical location information, and determining the corresponding 3GPP NTN cell based on the corresponding number of terminals to be accessed; for each beam identifier corresponding to a beam in the beam set, determining the uplink frequency and uplink bandwidth allocated to the corresponding 3GPP NTN cell in the 3GPP NTN from the authorized bandwidth resources based on the number of corresponding 3GPP NTN cells and the corresponding uplink resource authorization list; for each beam identifier corresponding to a beam in the beam set, determining the downlink frequency and downlink bandwidth allocated to the corresponding 3GPP NTN cell in the 3GPP NTN from the authorized bandwidth resources based on the number of corresponding 3GPP NTN cells and the corresponding downlink resource authorization list; for each beam identifier corresponding to a beam in the beam set, determining the uplink frequency and downlink bandwidth allocated to the corresponding 3GPP NTN cell in the 3GPP NTN from the authorized bandwidth resources based on the number of corresponding 3GPP NTN cells and the corresponding downlink resource authorization list; for each beam identifier corresponding to a beam in the beam set, determining the uplink frequency and downlink bandwidth allocated to the corresponding 3GPP NTN cell in the 3GPP NTN from the authorized bandwidth resources based on the number of corresponding 3GPP NTN cells and the corresponding downlink resource authorization list; and for each beam identifier corresponding to a beam in the beam set, determining the uplink frequency and downlink bandwidth allocated to the corresponding 3GPP NTN cell in the 3GPP NTN from the authorized bandwidth resources based on the number of corresponding 3GPP NTN cells and the corresponding downlink resource authorization list. The uplink frequency, downlink frequency, uplink bandwidth, and downlink bandwidth allocated in the NTN determine the configuration information of the corresponding 3GPP NTN baseband; for each beam identifier in the beam set, the corresponding RF transceiver frequency of the 3GPP NTN baseband is configured according to the configuration information of the corresponding 3GPP NTN baseband.

[0096] It should be noted that, in the embodiments of the present invention, the first baseband module, for each beam identifier in the beam set, first determines the number of terminals to be accessed based on the corresponding coverage area and geographical location information, and then determines the corresponding 3GPP NTN cell based on the number of terminals to be accessed; then, based on the number of corresponding 3GPP NTN cells and the corresponding uplink resource grant list, it determines the uplink frequency and uplink bandwidth allocated to the corresponding 3GPP NTN cell in the 3GPP NTN from the granted bandwidth resources; while determining the allocated uplink frequency and uplink bandwidth for each beam identifier in the beam set, it can also determine the corresponding downlink frequency and downlink bandwidth allocated to the corresponding 3GPP NTN cell in the 3GPP NTN from the granted bandwidth resources according to the same implementation process, i.e., based on the number of corresponding 3GPP NTN cells and the corresponding downlink resource grant list; finally, for each beam identifier in the beam set, based on the corresponding 3GPP NTN cell, it determines the allocated downlink frequency and downlink bandwidth of the corresponding 3GPP NTN cell in the 3GPP NTN from the granted bandwidth resources; The uplink frequency, downlink frequency, uplink bandwidth, and downlink bandwidth allocated in the 3GPP NTN cell determine the configuration information of the corresponding 3GPP NTN baseband. Then, based on the configuration information of the corresponding 3GPP NTN baseband, the radio frequency transceiver frequency of the corresponding 3GPP NTN baseband is configured.

[0097] It should be noted that, in the embodiments of the present invention, if there are a large number of terminals to be accessed within the beam coverage area, more 3GPP NTN cells can be allocated accordingly. In this case, the multiple allocated 3GPP NTN cells overlap and cover each other.

[0098] Specifically, in the embodiments of the present invention, after configuring the corresponding 3GPP NTN baseband radio frequency transceiver frequency for each beam identifier in the beam set according to the configuration information of the corresponding 3GPP NTN baseband, the first baseband module can also perform the following steps: for each beam identifier in the beam set, using the corresponding 3GPP NTN cell, the radio frequency transceiver frequency configured by the corresponding 3GPP NTN baseband is sent to the target converged terminal located in the cell of the 3GPP NTN converged terminal, so that the target converged terminal can access the 3GPP NTN.

[0101] Figure 3 This is a schematic diagram illustrating an exemplary resource sharing process provided in an embodiment of the present invention. Figure 3 As shown, taking the first baseband module as a 3GPP NTN baseband and the second baseband module as a DVB-S2 / RCS baseband as an example, the discussion is carried out by establishing an interactive interface between the 3GPP NTN baseband and the DVB-S2 / RCS baseband to realize communication between the 3GPP NTN baseband and the DVB-S2 / RCS baseband. The specific implementation process is as follows: The 3GPP NTN baseband sends a network deployment information request to the terrestrial operator's core network and receives the geographical location information and coverage area information from the terrestrial operator's core network in response to the network deployment information request; it also sends a parameter acquisition request to the DVB-S2 / RCS baseband through an interactive interface and receives the satellite platform parameters from the DVB-S2 / RCS baseband in response to the parameter acquisition request; after obtaining the geographical location information, coverage area information, and satellite platform parameters, it determines the resource requirement information based on the obtained information, and then sends the resource requirement information to the DVB-S2 / RCS baseband through the interactive interface, and receives the resource authorization result from the DVB-S2 / RCS baseband in response to the resource request. After obtaining the resource authorization result, which includes the authorized resource information, it allocates the authorized bandwidth resources in the 3GPP NTN and sends them to the 3GPP NTN converged terminal through broadcast or system messages, so that the 3GPP NTN converged terminal can access the authorized bandwidth resources according to the received broadcast or system messages.

Through the interaction interface, receive the resource request sent by the first baseband module based on the resource requirement information, and send the resource authorization result in response to the resource request to the first baseband module; wherein, the resource requirement information is information indicating the bandwidth resource requirement matching 3GPP NTN.

[0106] It should be noted that, in the embodiments of the present invention, the second baseband module can be a DVB-S2 / RCS baseband that supports the DVB-S2 / RCS protocol.

[0107] It should be noted that, in the embodiments of the present invention, when the second baseband module receives a resource request sent by the first baseband module based on resource demand information, it will determine the resource authorization result based on the resource request, and then send the resource authorization result to the first baseband module.

[0110] Specifically, in embodiments of the present invention, the resource authorization result includes: authorized resource information, or no matched authorized resource information; when the resource authorization result includes authorized resource information, before the second baseband module sends the resource authorization result in response to the resource request to the first baseband module, the following steps may also be performed: for each beam in the beam set, obtain the corresponding beam uplink frequency band, beam uplink bandwidth, beam downlink frequency band, and beam downlink bandwidth, and determine the frequency bands in the corresponding beam uplink frequency band and beam uplink bandwidth that overlap with the terminal uplink frequency band, and the frequency bands in the corresponding beam downlink frequency band and beam downlink bandwidth that overlap with the terminal downlink frequency band, to obtain the corresponding uplink overlapping frequency band and downlink overlapping frequency band; obtain satellite resource usage information, and for each beam in the beam set, within the corresponding uplink overlapping frequency band, determine the corresponding number of available uplink frequency points in the cell based on the satellite resource usage information and the corresponding number of uplink frequency point requirements and uplink bandwidth requirements.

Finally, for each beam in the beam set, an uplink resource grant list is generated based on the available uplink frequencies for the corresponding cell, and the frequency, bandwidth, start time, and duration of the corresponding forward feeder link sub-channel. Similarly, a downlink resource grant list is generated based on the available downlink frequencies for the corresponding cell, and the frequency, bandwidth, start time, and duration of the corresponding backfeed link sub-channel. The beam identifier, the corresponding uplink resource grant list, and the corresponding downlink resource grant list for each beam in the beam set are then identified as the granted resource information.

[0112] It should be noted that, in the embodiments of the present invention, if the second baseband module does not match the resource requirement information, it will directly send the unmatched authorized resource information as the resource authorization result to the first baseband module through the interaction interface.
