[0203] In modern communication systems, satellite communication and terrestrial mobile communication system are two main communication modes. With the rapid development of communication technology, spectrum resources become increasingly scarce. While satellite systems and terrestrial mobile communication systems occupy different spectrum resources to realize data transmission and communication services, it will cause waste of spectrum resources.

[0208] FIG. 1b is an exemplary schematic diagram of a communication system provided by an embodiment of the present disclosure. As shown in FIG. 1b, when the satellite system uses the network device in the terrestrial mobile communication system to share the spectrum of the network device.

[0209] In this architecture, there can be some interference between the terrestrial mobile communication system and the satellite system, wherein the interference mainly includes the influence of the transmission of the network device on the satellite reception, and the influence of the satellite reception on the transmission of the network device.

[0210] In some embodiments of the present disclosure, the satellite system and the terrestrial mobile communication system are synchronized and use the same uplink and downlink frame structure, thereby reducing the interference. In this architecture, since the isolation between the uplink and the downlink needs to be ensured, the round trip propagation delay between the satellite terminal and the satellite needs to be considered.

[0211] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It can be known by those skilled in the art that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0212] The resource determination method, satellite access node, network device, communication apparatus, communication system, storage medium and program product provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0213] Referring to FIG. 2a, FIG. 2a is an interaction schematic diagram of the resource determination method provided by an embodiment of the present disclosure. As shown in FIG. 2a, the resource determination method comprises the following steps:

[0214] In step S2101, the network device sends first information to the SAN.

[0215] In some embodiments, the coverage range of the SAN includes one or more network devices. The SAN can use the frequency spectrum resource used by any one or more network devices for satellite communication. Accordingly, any one or more network devices can send the first information of the frequency spectrum resource used by the network device to the SAN.

[0216] In some embodiments, the one or more network devices in the coverage range of the SAN can be a network device group, and the network devices in the network device group can use the same frequency spectrum resource for communication. The network device in the above step can be any network device in the network device group.

[0217] In some embodiments, the first information is used to indicate the second frequency band resource occupied by the network device in the currently used second frequency spectrum resource.

[0218] In some embodiments, the name of the first information is not limited, which is, for example, “frequency spectrum resource information”, “resource occupation information”, “frequency spectrum resource occupation information”, “frequency band information”, etc.

[0219] In some embodiments, the first information is used to indicate at least one of the location information and the bandwidth occupation information of the second frequency band resource in the second frequency spectrum resource. The second frequency band resource is the frequency spectrum range occupied by the network device for communication in the second frequency spectrum resource.

[0220] In some embodiments, the location information of the second frequency band resource is used to indicate the carrier frequency location of the second frequency band resource occupied by the network device in the second frequency spectrum resource, and the bandwidth occupation information of the second frequency band resource is used to indicate the frequency spectrum width of the second frequency band resource.

[0221] In some embodiments, the network device can send the first information to the SAN through any known or unknown communication means, for example, the network device can send the first information to the SAN through the ground gateway (GW) corresponding to the SAN.

[0222] In some embodiments, the names of the first information, the location information, the bandwidth occupation information, and the like are not limited to the names described in the embodiments, and the terms "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "data", and the like can be replaced with each other.

[0223] In step S2102, the SAN determines, according to the first information, that the size of the unoccupied resource in the second spectrum resource is greater than or equal to the size of the required resource of the SAN, and determines the second spectrum resource as the first spectrum resource.

[0224] The second spectrum resource is a spectrum resource currently used by the network device.

[0225] In some embodiments, the first spectrum resource is a spectrum resource determined by the SAN and required to be shared by the network device.

[0226] In some embodiments, the occupied frequency band resource in the second spectrum resource includes, but is not limited to, one or more of the following: a second frequency band resource occupied by the network device in the second spectrum resource, a frequency band resource occupied by other satellites or communication devices, a third frequency band resource occupied by a guard interval (Gap), and the like. The unoccupied resource is a resource in the second spectrum resource other than the one or more occupied frequency band resources.

[0227] In some embodiments, the name of the guard interval is not limited, and it is, for example, "interval", "safety interval", and the like.

[0228] In some embodiments, the frequency band resource occupied by the guard interval refers to a frequency resource or a time resource reserved in the second spectrum resource to avoid interference between adjacent frequency bands.

[0229] In some embodiments, the SAN can analyze the service demand of the to-be-executed service to obtain the size of the required resource of the to-be-executed service. The service demand includes, but is not limited to, one or more of the following: bandwidth demand, network delay demand, data volume transmission demand, network performance demand, packet loss rate demand, and the like.

[0230] In the embodiments of the present disclosure, when the size of the unoccupied resource is greater than or equal to the size of the required resource of the SAN, it indicates that the unoccupied resource in the second spectrum resource can support the service of the SAN, and therefore, the second frequency band resource can be used as the first frequency band resource applied when the SAN performs satellite communication.

[0231] In step S2103, the SAN determines, according to the first information, a first frequency band resource occupied by the SAN from the first frequency spectrum resource except for the frequency band resource occupied by the network device.

[0232] In some embodiments, the first frequency band resource can be any frequency band resource in the first frequency spectrum resource except for the second frequency band resource.

[0233] In some embodiments, the first frequency band resource can be any frequency band resource in the first frequency spectrum resource except for the second frequency band resource and a third frequency band resource occupied by the guard interval.

[0234] In some embodiments, the first frequency band resource is at least partially different from the third frequency band resource occupied by the guard interval. The "at least partially different" means that the first frequency band resource and the third frequency band resource occupied by the guard interval can be completely different frequency bands, or the first frequency band resource and the third frequency band resource occupied by the guard interval can partially overlap.

[0235] In some embodiments, the third frequency band resource is used to separate the first frequency band resource and the second frequency band resource.

[0236] In step S2104, the SAN determines, according to the first information, that when the size of the unoccupied resource in the second frequency spectrum resource is less than the size of the required resource of the SAN, the third frequency spectrum resource is determined as the first frequency spectrum resource.

[0237] In some embodiments, when the size of the unoccupied resource in the second frequency spectrum resource is less than the size of the required resource of the SAN, it indicates that the available frequency band resource in the second frequency spectrum resource cannot support the SAN to process the to-be-executed service, and therefore, the second frequency band resource cannot be used as the first frequency band resource applied by the SAN in satellite communication.

[0238] In some embodiments, the SAN can determine other frequency spectrum resources (for example, the third frequency spectrum resource) as the first frequency spectrum resource applied by the SAN in satellite communication.

[0239] In some embodiments, the third frequency spectrum resource can be a predetermined available frequency spectrum resource.

[0240] In some embodiments, the third frequency spectrum resource can be determined based on the identification information sent by the network device.

[0241] In some embodiments, the terms "preset", "certain", "pre-set", "set", "indicated", "any", "first", and the like can be replaced by each other, and "certain A", "preset A", "pre-set A", "set A", "indicated A", "any A", "first A" can be interpreted as A predetermined in a protocol or the like, or A obtained by setting, configuration, or indication, or a specific A, any A, or first A, but are not limited thereto.

[0242] In some embodiments, the SAN can give up sharing the spectrum resource with the network device for communication if there is no other spectrum resource available at present.

[0243] In some embodiments, the third spectrum resource can be a spectrum resource used by any network device in one or more network device groups within the coverage of the SAN. Optionally, when the SAN and the network device share the spectrum, the spectrum resource that can be occupied by both the network device and the SAN can be determined as a predetermined spectrum resource, and when the SAN determines that the resource size of the available resource in the second spectrum resource is smaller than the resource size required by the SAN for performing the service, any spectrum resource in the predetermined spectrum resource can be determined as the third spectrum resource.

[0244] In some embodiments, the third spectrum resource can be a spectrum resource used by the network device or the network device group closest to the SAN in the predetermined spectrum resource.

[0245] In some embodiments, the third spectrum resource can be a spectrum resource with the smallest occupied frequency band resource size in the predetermined spectrum resource.

[0246] In some embodiments, the third spectrum resource can be a spectrum resource with the smallest number of occupied frequency band resources in the predetermined spectrum resource.

[0247] In some optional embodiments, when performing the above step S2104, the following step 1 to step 2 can be specifically included:

[0248] Step 1, the SAN sends first indication information to the network device, and the first indication information is used to request switching of the spectrum resource.

[0249] In some embodiments, the SAN can carry identification information of the third spectrum resource in the first indication information.

[0250] In some embodiments, the SAN can carry a switching instruction for requesting switching of the spectrum resource in the first indication information.

[0251] In some embodiments, the SAN can carry the switching instruction for requesting switching of the spectrum resource and the identification information of the third spectrum resource in the first indication information.

[0252] In some embodiments, the SAN can carry the guard interval information in the first indication information.

[0253] In some embodiments, the SAN can send the identification information of the third spectrum resource and / or the guard interval information to the network device after sending the first indication information. That is, the identification information of the third spectrum resource and / or the guard interval information can be carried in the first indication information or not.

[0254] The guard interval information is used to indicate one or more of the following information of the guard interval in the frequency band resource of the spectrum resource: frequency spectrum width, location, etc.

[0255] Correspondingly, the network device judges whether the spectrum resource can be switched after receiving the first indication information, and sends response information to the SAN based on the judgment result.

[0256] In some embodiments, if the identification information of the third spectrum resource is not carried in the first indication information, the network device determines whether there is other predetermined spectrum resource that can be switched at present, whether there is other service in the predetermined spectrum resource, and whether the other service will affect the SAN using the spectrum resource.

[0257] In some embodiments, when the network device determines that there is no predetermined spectrum resource that can be switched at present, or the predetermined spectrum resource has other service resulting in that the spectrum resource cannot be used, it is determined that the spectrum resource cannot be switched.

[0258] In some embodiments, if the network device determines that there is predetermined spectrum resource that can be switched at present, and there is no other service in the predetermined spectrum resource or the other service does not affect the SAN using the spectrum resource, it is determined that the spectrum resource can be switched.

[0259] In some embodiments, if the identification information of the third spectrum resource is carried in the first indication information, the network device can determine the third spectrum resource to be switched based on the identification information, and determine whether the third spectrum resource can be switched. For example, the network device can determine whether the third spectrum resource has other service resulting in that the third spectrum resource cannot be used, and if the network device determines that the third spectrum resource has no other service or the other service does not affect the SAN using the third spectrum resource, it is determined that the third spectrum resource can be switched.

[0260] In some embodiments, when the network device determines that the spectrum resource can be switched, the second indication information that the spectrum resource can be switched is sent to the SAN.

[0261] In some embodiments, the network device determines that the spectrum resource cannot be switched, and sends second indication information that the spectrum resource cannot be switched to the SAN.

[0262] In some embodiments, the second indication information sent by the network device to the SAN can further carry identification information of the third spectrum resource.

[0263] Step 2, when the SAN receives the second indication information sent by the network device for indicating that the spectrum resource can be switched, the third spectrum resource is determined as the first spectrum resource.

[0264] In some embodiments, when the SAN receives the second indication information for indicating that the spectrum resource can be switched, if the second indication information carries identification information, the third spectrum resource is determined according to the identification information, and the third spectrum resource is determined as the first spectrum resource used by the SAN for satellite communication.

[0265] In some embodiments, when the SAN receives the second indication information for indicating that the spectrum resource can be switched, if the second indication information does not carry identification information, the third spectrum resource is determined from the predetermined spectrum resource, and the third spectrum resource is determined as the first spectrum resource used by the SAN for satellite communication.

[0266] Step S2105, the SAN sends third indication information to the network device.

[0267] In some embodiments, the third indication information is used to instruct the network device to switch to the third spectrum resource.

[0268] In some embodiments, the third indication information can carry identification information of the third spectrum resource.

[0269] In some embodiments, the third indication information can carry switching instruction for indicating switching of the spectrum resource.

[0270] In some embodiments, the third indication information carries switching instruction for indicating switching of the spectrum resource and identification information of the third spectrum resource.

[0271] In some embodiments, the third indication information can carry guard interval information.

[0272] In some embodiments, the SAN can send identification information and / or guard interval information of the third spectrum resource to the network device after sending the third indication information. That is, the identification information and / or the guard interval information of the third spectrum resource can be carried in the third indication information, or can not be carried in the third indication information.

[0273] The guard interval information is used to indicate one or more information of the frequency spectrum width and the location of the guard interval in the frequency band resource of the spectrum resource.

[0274] In some embodiments, after receiving the third indication information, the network device determines the second frequency band resource occupied by the network device in the first frequency spectrum resource according to the size of the required resource of the network device.

[0275] In some embodiments, the second frequency band resource can be a continuous frequency band resource in the first frequency spectrum resource.

[0276] In some embodiments, the second frequency band resource can also be a combination of multiple non-continuous frequency band resources in the first frequency spectrum resource, wherein the total resource size of the multiple frequency band resources is greater than or equal to the size of the required resource of the network device.

[0277] In step S2106, the SAN determines the first frequency band resource occupied by the SAN in the first frequency spectrum resource according to the size of the required resource of the SAN.

[0278] In some embodiments, the first frequency band resource can be a continuous frequency band resource in the first frequency spectrum resource.

[0279] In some embodiments, the first frequency band resource can also be a combination of multiple non-continuous frequency band resources in the first frequency spectrum resource, wherein the total resource size of the multiple frequency band resources is greater than or equal to the size of the required resource of the SAN.

[0280] In some embodiments, the first frequency band resource can also be a combination of multiple non-continuous frequency band resources in the first frequency spectrum resource, wherein the total resource size of the multiple frequency band resources is greater than or equal to the size of the required resource of the SAN.

[0281] In step S2107, the SAN sends fourth indication information to the network device.

[0282] In some embodiments, the fourth indication information is used to indicate the first frequency band resource occupied by the SAN in the first frequency spectrum resource.

[0283] In some embodiments, when the first frequency spectrum resource is the third frequency spectrum resource, the SAN can first occupy the first frequency band resource in the first frequency spectrum resource, and then the network device can occupy the second frequency band resource used by the network device in the resource of the first frequency spectrum resource except the occupied resource.

[0284] In this embodiment, the SAN can send the first frequency band resource occupied by the SAN in the first frequency spectrum resource to the network device through the fourth indication information, so as to avoid the network device from occupying the same resource as the SAN when occupying the second frequency band resource in the first frequency spectrum resource.

[0285] In some embodiments, the fourth indication information can include position information and bandwidth information of the first frequency band resource in the first frequency spectrum resource.

[0286] In some embodiments, the fourth indication information can carry guard interval information.

[0287] In step S2108, the network device determines, according to the fourth indication information, a second frequency band resource occupied by the network device in the first frequency spectrum resource.

[0288] In some embodiments, the network device determines, according to the fourth indication information, a first frequency band resource occupied by the SAN in the first frequency spectrum resource, and determines the second frequency band resource in the unoccupied resource in the first frequency spectrum resource except the first frequency band resource.

[0289] In some embodiments, the network device determines, according to the fourth indication information, a first frequency band resource occupied by the SAN in the first frequency spectrum resource and a third frequency band resource occupied by the guard interval, and determines the second frequency band resource in the unoccupied resource in the first frequency spectrum resource except the first frequency band resource and the third frequency band resource.

[0290] In some embodiments, the second frequency band resource can be a frequency band resource farthest from the first frequency band resource in the first frequency spectrum resource. Specifically, when there are multiple discontinuous unoccupied frequency band resources in the first frequency spectrum resource, the distance between each unoccupied resource and the first frequency band resource can be obtained, and the unoccupied frequency band resource farthest from the first frequency band resource is determined as the second frequency band resource.

[0291] In some embodiments, the second frequency band resource can be a frequency band resource closest to the first frequency band resource. Specifically, when there are multiple discontinuous unoccupied frequency band resources in the first frequency spectrum resource, the distance between each unoccupied frequency band resource and the first frequency band resource can be obtained, and the frequency band resource closest to the first frequency band resource is determined as the second frequency band resource.

[0292] In some embodiments, the resource size of the second frequency band resource is greater than or equal to the size of the required resource of the network device. Specifically, when there are multiple unoccupied frequency band resources in the first frequency spectrum resource, any unoccupied frequency band resource with a resource size greater than or equal to the size of the required resource of the network device can be determined as the second frequency band resource.

[0293] In some embodiments, when there are multiple unoccupied frequency band resources with a resource size greater than or equal to the size of the required resource of the network device in the first frequency spectrum resource, the frequency band resource with the smallest difference in resource size from the size of the required resource of the network device can be determined from the multiple unoccupied frequency band resources as the second frequency band resource.

[0294] In some embodiments, any two of the first indication information, the third indication information, and the fourth indication information can be the same information; or the first indication information, the third indication information, and the fourth indication information can be the same information.

[0295] Step S2109. The network device sends fifth indication information to the SAN.

[0296] In some embodiments, the fifth indication information is used to indicate the second frequency band resource occupied by the network device in the first frequency spectrum resource.

[0297] In some embodiments, when the first frequency spectrum resource is a third frequency spectrum resource, the network device can first occupy the second frequency band resource in the first frequency spectrum resource, and then the SAN occupies the first frequency band resource used by the SAN in the resource other than the occupied resource in the first frequency spectrum resource.

[0298] In this embodiment, the network device can send the second frequency band resource occupied by the network device in the first frequency spectrum resource to the SAN through the fifth indication information, so as to avoid the SAN occupying the same resource as the network device when occupying the first frequency band resource in the first frequency spectrum resource.

[0299] In some embodiments, the fifth indication information can include location information and bandwidth information of the second frequency band resource in the first frequency spectrum resource.

[0300] In some embodiments, the fifth indication information can carry guard interval information.

[0301] Step S2110. The SAN determines the first frequency band resource occupied by the SAN in the first frequency spectrum resource according to the fifth indication information.

[0302] In some embodiments, the SAN determines the second frequency band resource occupied by the network device in the first frequency spectrum resource according to the fifth indication information, and determines the first frequency band resource in the resource other than the second frequency band resource in the first frequency spectrum resource.

[0303] In some embodiments, the SAN determines the second frequency band resource occupied by the network device in the first frequency spectrum resource and the third frequency band resource occupied by the guard interval according to the fifth indication information, and determines the second frequency band resource in the resource other than the second frequency band resource and the third frequency band resource in the first frequency spectrum resource.

[0304] In some embodiments, the first frequency band resource can be the frequency band resource farthest from the second frequency band resource in the first frequency spectrum resource. Specifically, when there are multiple discontinuous unoccupied frequency band resources in the first frequency spectrum resource, the distance between each unoccupied resource and the second frequency band resource can be obtained, and the unoccupied frequency band resource farthest from the second frequency band resource is determined as the first frequency band resource.

[0305] In some embodiments, the first frequency band resource can be the frequency band resource closest to the second frequency band resource. Specifically, when there are multiple discontinuous unoccupied frequency band resources in the first frequency spectrum resource, the distance between each unoccupied frequency band resource and the second frequency band resource can be obtained, and the frequency band resource closest to the second frequency band resource is determined as the first frequency band resource.

[0306] In some embodiments, the resource size of the first frequency band resource is greater than or equal to the size of the required resource of the network device. Specifically, when there are multiple unoccupied frequency band resources in the first frequency spectrum resource, any unoccupied frequency band resource with a resource size greater than or equal to the required resource of the network device can be determined as the first frequency band resource.

[0307] In some embodiments, when there are multiple unoccupied frequency band resources with a resource size greater than or equal to the size of the required resource of the network device in the first frequency spectrum resource, the frequency band resource with the smallest difference between the resource size and the size of the required resource of the network device can be determined from the multiple unoccupied frequency band resources as the first frequency band resource.

[0308] In some embodiments, the fifth indication information and the second indication information can be the same information.

[0309] Step S2111, the SAN communicates based on the first frequency band resource occupied by the SAN.

[0310] In some embodiments, the first frequency band resource is a frequency band resource in the first frequency spectrum resource, except for the second frequency band resource. For example, please refer to FIG. 2c, which is an exemplary schematic diagram of the occupation of the first frequency spectrum resource according to an embodiment of the present disclosure. As shown in FIG. 2c, the first frequency band resource is any one of the unoccupied frequency band resource 1 or the unoccupied frequency band resource 2.

[0311] In some embodiments, the first frequency band resource can be a continuous frequency band resource, for example, the first frequency band resource is a segment of frequency band resource in any one of the unoccupied frequency band resource 1 or the unoccupied frequency band resource 2.

[0312] In some embodiments, the first frequency band resource can also be a non-continuous frequency band resource. For example, the first part of the first frequency band resource is a frequency band resource in the unoccupied frequency band resource 1, and the second part of the first frequency band resource is a frequency band resource in the unoccupied frequency band resource 2. The sum of the resource sizes occupied by the first part and the second part is greater than or equal to the required resource size of the SAN.

[0313] In some embodiments, the first frequency band resource is a frequency band resource in the first frequency spectrum resource, other than the second frequency band resource and the third frequency band resource, and the third frequency band resource is used to separate the first frequency band resource and the second frequency band resource. For example, refer to FIG. 2d, which is a schematic diagram of an example of occupation of a first frequency spectrum resource according to an embodiment of the present disclosure. As shown in FIG. 2d, the first frequency band resource is any one of the unoccupied frequency band resource 1, the unoccupied frequency band resource 2, or the unoccupied frequency band resource 3.

[0314] In some embodiments, the first frequency band resource can be a continuous frequency band resource, for example, the first frequency band resource is a frequency band resource in any one of the unoccupied frequency band resource 1, the unoccupied frequency band resource 2, or the unoccupied frequency band resource 3.

[0315] In some embodiments, the first frequency band resource can also be a non-continuous frequency band resource. For example, a first part of the first frequency band resource is a frequency band resource in the unoccupied frequency band resource 1, a second part of the first frequency band resource is a frequency band resource in the unoccupied frequency band resource 2, and a third part of the first frequency band resource is a frequency band resource in the unoccupied frequency band resource 3. The sum of the resource sizes occupied by the first part, the second part, and the third part is greater than or equal to the resource size required by the SAN.

[0316] In some embodiments, the first frequency band resource is a frequency band resource in the first frequency spectrum resource, which is farthest from the second frequency band resource. For example, refer to FIG. 2d, as shown in FIG. 2d, the first frequency band resource can be a frequency band resource in the unoccupied frequency band resource 3, which is farthest from the second frequency band resource, and the resource size of the unoccupied frequency band resource 3 is greater than or equal to the resource size required by the SAN.

[0317] In some embodiments, the resource size of the first frequency band resource is greater than or equal to the resource size required by the SAN. For example, refer to FIG. 2d, as shown in FIG. 2d, if the size of the unoccupied frequency band resource 3 is less than the resource size required by the SAN, the first frequency band resource can be a frequency band resource in the unoccupied frequency band resource 2, which is farthest from the second frequency band resource, other than the unoccupied frequency band resource 3.

[0322] In some embodiments, steps S2107-S2108 and steps S2109-S2110 can be replaced with each other in different embodiments.

[0323] In the embodiments of the present disclosure, the SAN and the network device can share the same spectrum resource for communication, which can improve the utilization rate of the spectrum resource, and the SAN and the network device occupy different frequency band resources in the first spectrum resource, which can avoid interference between the network device and the SAN and guarantee the communication quality of the SAN and the network device.

[0324] Referring to FIG. 2b, FIG. 2b is an exemplary interaction schematic diagram of a resource determination method according to an embodiment of the present disclosure. As shown in FIG. 2b, the resource determination method includes the following steps:

[0325] In step S2201, the SAN acquires interference information in the second spectrum resource currently used by the network device.

[0326] In some embodiments, the SAN acquires the above interference information periodically.

[0327] In some embodiments, the above interference information is acquired when the SAN needs to occupy the spectrum resource to perform a service.

[0328] In some embodiments, the SAN receives the interference information sent by the network device, but is not limited thereto, and can also receive the interference information sent by other subjects.

[0329] In some embodiments, the network device sends the current interference information of the network device to the SAN according to a certain period.

[0332] In some embodiments, the SAN can also receive interference data sent by other network devices, and obtain interference information in the second spectrum resource based on the interference data.

[0333] In some embodiments, the interference information includes at least one of interference intensity and interference to noise (I / N).

[0334] In some embodiments, the interference information can also be referred to as "interference condition", "interference size", etc.

[0335] In step S2202, when the interference information meets the preset requirement, the second spectrum resource is determined as the first spectrum resource.

[0336] In some embodiments, when the interference information is the interference intensity, the interference information meets the preset requirement if the interference intensity is less than or equal to a first preset threshold.

[0337] In some embodiments, when the interference information is the interference to noise, the interference information meets the preset requirement if the interference to noise is greater than or equal to a second preset threshold.

[0338] It should be noted that the specific size of the first preset threshold and the second preset threshold is not limited in the embodiments of the present disclosure.

[0339] In the embodiments of the present disclosure, when the interference information meets the preset requirement, it indicates that the interference in the second spectrum resource currently used by the network device is small, and the SAN can share the second spectrum resource with the network device. At this time, the SAN can determine the second spectrum resource as the first spectrum resource.

[0340] In step S2203, when the interference information does not meet the preset requirement, a predetermined third spectrum resource is determined as the first spectrum resource.

[0341] In some embodiments, when the interference information is the interference strength, the interference information does not meet the preset requirement is that the interference strength is greater than a first preset threshold.

[0342] In some embodiments, when the interference information is the interference-to-noise ratio, the interference information does not meet the preset requirement is that the interference-to-noise ratio is less than a second preset threshold.

[0343] In the embodiments of the present disclosure, when the interference strength in the second frequency spectrum resource is greater than the first preset threshold and / or the interference-to-noise ratio is less than or equal to the second preset threshold, it indicates that the interference in the second frequency spectrum resource currently used by the network device is large, and if the SAN and the network device share the second frequency spectrum resource, it will affect the normal communication of the SAN, therefore, the second frequency spectrum resource cannot be used as the first frequency spectrum resource for the satellite communication of the SAN.
