[0060] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions of the present application are further described in detail below in combination with the drawings and embodiments, and the described embodiments should not be regarded as limiting the present application, and all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0061] In the following description, “some embodiments” are related to a subset of all possible embodiments, but it can be understood that “some embodiments” can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict. The term “first / second” referred to is only to distinguish similar objects, and does not represent a specific order of the objects. Understandably, “first / second” can be interchanged in a specific order or sequence as allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0062] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used herein are only for the purpose of describing the present application and are not intended to limit the present application.

[0063] With the rapid development of national digital transformation, scenarios with large bandwidth, low latency and high concurrency are emerging, and netizens' demand for fast access to web pages, videos, games and other content is becoming more and more urgent. Content Delivery Network (CDN) is a very effective technology to shorten the latency. The key point of content delivery is to shorten the physical distance between users and content to shorten the waiting time of users. CDN uses more cache servers (CDN edge nodes) to be placed in areas or networks with relatively concentrated user access. When users access a website, CDN can not only cache video content, but also distribute static resources (such as various types of pictures, etc.) of the website and static content (such as installation package files, pictures and videos in the application program, etc.) of the mobile application (APP). CDN is a service developed from the traditional Internet technology industry. At the same time, for the communication field, CDN also has great commercial value. Internet service providers use CDN to exchange latency for storage, and spend money to purchase CDN servers or cloud computing services to exchange for better user experience. Communication operators also pursue CDN, but the purpose of the present application is to exchange bandwidth for storage - by sinking services, reducing the traffic pressure of the upper backbone network, avoiding hardware expansion, and reducing network construction cost.

[0064] Satellite communication is a kind of wireless communication, which is different from ordinary wireless communication in that the repeater is located on the artificial satellite in the sky. It expands the coverage distance of the base station and can reach some areas that cannot be covered by ground wireless signals, such as oceans, mountains, forests, deserts, plateaus and uninhabited areas. Satellite communication was initially used for military purposes. With the development of science and technology, it has gradually developed into military and civilian dual-use. With the successful trial of high-bandwidth and high-throughput satellites, satellite communication can provide more and more services. Satellite communication has developed rapidly in recent years, and satellite communication has been integrated into daily life, such as satellite television, maritime satellite telephone, and the planned 6th Generation Mobile Communication Technology (6G) mobile communication will also use low earth orbit satellites as signal relays.

[0065] In recent years, with the popularization and development of the Internet / Internet of Things, the integration of satellite networks and the 5th Generation Mobile Communication Technology (5G) and the deep application of 6G have become the focus of the communication network industry. The integrated network of satellite communication and ground network combines the advantages of satellite network and ground network to achieve the goal of "always online" information communication in all-weather / all-territory. The existing related technologies and solutions about the integration of satellite network and ground network and the related application scenarios based on the integrated network are currently in the research and planning stage.

[0066] In the related art, mature CDN products and technologies are based on ground network construction and provide services directly to wired and wireless network users. Users in areas such as oceans, mountains, and deserts without network coverage cannot be served. Although satellite communication has a wide coverage and strong disaster recovery and security capabilities, its network performance is easily affected by climate and obstructions, and the bandwidth and storage resources of satellite equipment are limited.

[0067] Therefore, the embodiments of the present application provide a resource distribution method. Based on the label of the requested resource in the resource request, it is determined whether the requested resource is only distributed on the satellite node. If not, the resource is preferentially obtained from the ground node and sent to the resource requester, effectively integrating ground network and satellite network communication. Users can obtain resources from ground nodes and / or network nodes, and when both have the requested resources, resources are preferentially obtained from the ground, reducing the communication load pressure of the satellite. The method provided by the embodiments of the present application can be executed by the processor of a computer device. The computer device can be a server, a notebook computer, a tablet computer, a desktop computer, a mobile device (such as a mobile communication tool, a mobile satellite vehicle), and the like.

[0069] The satellite ground station 11 is located in the ground network coverage area, used for determining the distribution node of the to-be-distributed resource based on the label of the to-be-distributed resource, performing security verification on the in-station resource, wherein the in-station resource includes the self-owned resource of the satellite ground station 11 and the received resource to be distributed to the satellite node sent by the content source station 12, and the resource is distributed to the satellite node 6-8 after verification (only part is shown in the figure), the resource is distributed to the ground node 1-5 (only part is shown in the figure), the resource is sent to the ground user 16 through the base station in the area where the ground user 16 is located, and the content source station 12 is communicated, the communication includes sending resources, receiving resources, etc.

The satellite terminal 17 can be a satellite phone, a satellite data terminal, or a smart phone with a satellite call function.

[0075] The satellite terminal 17 and the intranet / safe-restricted network user 18 can send a resource request to the satellite nodes 6-8, and receive a returned resource of the satellite nodes after passing the authority verification.

[0076] Figure 2 A structure schematic diagram of a resource distribution system 20 provided by an embodiment of the present application is shown in FIG. 1. The system includes a first source station 21, a base station 22, a ground node 23, and a satellite node 24, wherein:

[0078] The base station 22 is configured to receive a resource request, determine whether a requested resource is only distributed at the satellite node based on a label of the requested resource, obtain the requested resource from the ground node if the requested resource is not only distributed at the satellite node, and send the requested resource to a resource requestor.

[0080] The satellite node 24 is configured to receive the resource distributed by the first source station and receive the resource request, obtain the requested resource of the resource request, and send the requested resource to the resource requester.

[0082] The second source station is configured to receive the to-be-distributed resource distributed by the first source station to the satellite node, perform content legality verification on the to-be-distributed resource, and send the to-be-distributed resource to the satellite node after passing the verification.

[0083] Figure 3 A flowchart of a resource distribution method provided by an embodiment of the present application is applied to a base station. As shown in Figure 3 The method can include steps 301 to 304, wherein:

[0084] Step 301: receiving a resource request.

[0085] In some embodiments, the base station is a public mobile communication base station, which mainly provides wireless network coverage, that is, implements wireless signal transmission between a wired / wireless communication network and a wireless terminal. When a ground user, that is, a user in a wireless network coverage area, requests a resource, the resource request of the user is not directly sent to a resource provider, but the resource request of the user is received by the base station, and then the resource request of the user is forwarded to a corresponding node by the base station.

[0086] It should be noted that communication through the base station is limited to users in a wireless / wireless network coverage area, and users in a network restricted area or not in a wireless / wireless network coverage area cannot establish communication with the node through the base station to obtain resources, that is, the received resource request can be considered to come from a user in a wireless / wireless network coverage area.

[0087] Based on the above embodiment, the resource request of the user is received by the base station instead of direct communication between the user and the node, which provides a prerequisite condition for subsequent pre-determination of a resource distribution range based on a tag and then diverting the request to a corresponding node, thereby improving communication efficiency.

[0088] Step 302: determining whether the requested resource is only distributed in the satellite node based on a tag of the resource requested by the resource request.

[0089] The label represents the security level and / or distribution range of the resource; the resource is distributed to the satellite node and / or ground node by the first source station based on the label of the resource.

[0090] In some embodiments, the base station can identify the label corresponding to the resource requested by the user. Exemplarily, the base station can pre-store the correspondence between the resource and the label. After the base station receives the resource request, the base station can determine the label corresponding to the resource requested by the resource request, and then determine the distribution node of the resource based on the label. For example, whether the requested resource is only distributed on the satellite node. It should be noted that, in order to ensure the security of the resource, some resources are only distributed on the satellite node, while some resources can be distributed on the satellite node and the ground node at the same time. Meanwhile, in order to save the storage resource of the satellite, some resources are only distributed on the ground node.

[0091] In some embodiments, the label includes the security level and / or distribution range of the resource. Exemplarily, for some confidential information such as military communication information or confidential resources, the security level can be set for such resources, and the distribution range thereof is limited. Here, in order to reduce the workload of the system, the security level can be set only for the resources distributed on the satellite node. For example, the security level of the confidential resource is set to high, and the access to the resource with high security level needs corresponding instruction or secret key, and the ordinary user cannot access or view the resource through the satellite node. In addition, the distribution range of the resource refers to the geographical area, i.e. to establish a geographical fence. For example, the resource A is distributed to the ground node in the a area or the satellite node covering the a area. At this time, the user outside the a area cannot access the resource A. It should be noted that when the user accesses a resource, the security level and the distribution range of the resource need to be met at the same time.

[0092] In some embodiments, the resource is distributed to the satellite node and / or the ground node by the first source station based on a label of the resource. Wherein the first source station is a resource provider, the resource provider labels the resource with a corresponding label when providing the resource, and then determines the distribution node of the resource based on the label of the resource. Wherein the label can include the security level and / or the distribution range of the resource, and further can represent the node to which the corresponding resource needs to be distributed. Here, it can not only be determined to be distributed to the ground node and / or the satellite node, but also to a specific node, such as a certain node in the ground node. Exemplarily, the label of a certain resource a is to be distributed to the ground node, the security level is high, and the distribution range is A area. At this time, the resource a will be distributed to the ground node in the A area, and only users with high security level permission are allowed to access. It should be noted that the storage resource of the node is limited, and the resource provided by the resource provider is constantly updated. Therefore, when distributing the resource, the first source station will not distribute all resources to the corresponding node based on the label. An alternative method can be based on past data to count the resources with access frequency higher than a threshold in the resource request received by the node within a certain period of time, and these resources are preferentially distributed. For other resources with low access frequency, the resources can be temporarily not distributed to save the storage space of the node.

[0093] Based on the above embodiments, the node to which the resource is distributed is determined based on the label of the resource, which can direct the resource request of the user to the correct node to ensure that the user can quickly obtain the resource, avoid multiple searches, and improve the efficiency of the user obtaining the resource.

[0094] Step 303, if the requested resource is not only distributed in the satellite node, obtaining the requested resource from the ground node.

[0095] In some embodiments, determining whether the resource is only distributed in the satellite node based on the label of the resource means whether the resource is only distributed to the satellite node when distributed, and whether the resource actually exists on the satellite node cannot be determined. Only it can be determined that the resource does not exist in the ground node. If the requested resource is not only distributed in the satellite node, the resource can be a resource distributed in the satellite node and the ground node or only in the ground node. For the resource distributed in both nodes, the resource is preferentially obtained from the ground node. On the one hand, obtaining the resource from the ground node produces lower network delay than obtaining the resource from the satellite node. On the other hand, the bandwidth of the satellite is limited, and unnecessary resource requests are not occupied by satellite communication. For the resource distributed only in the ground node, the requested resource can only be obtained from the ground node.

[0096] Based on the above embodiment, when resources are distributed to ground nodes and satellite nodes at the same time, the resources are preferentially obtained from the ground nodes, avoiding excessive occupation of satellite communication bandwidth, and the ground communication is more efficient and faster, improving the user experience.

[0097] In step 304, the requested resource is sent to the resource requester.

[0098] In some embodiments, after obtaining the requested resource of the resource requester, the resource is forwarded to the resource requester. It should be noted that the base station itself does not store the resource, and the resource requester, such as a user, needs to establish a connection with the node through the base station. The node and the user's direct communication object are all the base station. The node returns the requested resource after responding to the resource request. The base station directly forwards the resource to the user after receiving the returned resource. In this way, the user can obtain the requested resource.

[0099] Based on the above embodiment, based on the label of the resource requested by the resource request, it is determined whether the requested resource is only distributed on the satellite node. If it is not only distributed on the satellite node, the resource is preferentially obtained from the ground node and sent to the resource requester. The ground network and satellite network communication are effectively integrated. The user can obtain the resource from the ground node and / or network node. When both have the requested resource, the resource is preferentially obtained from the ground, reducing the communication load pressure of the satellite. Obtaining the resource from the ground node also reduces the network delay of the user obtaining the resource.

[0100] The technical scheme provided by the embodiment of the application is that the base station receives a resource request, determines whether the requested resource is only distributed on the satellite node based on the label of the resource requested by the resource request. If the requested resource is not only distributed on the satellite node, the requested resource is obtained from the ground node and sent to the resource requester. The label represents the security level and / or distribution range of the resource. The resource is distributed to the satellite node and / or ground node by the first source station based on the label of the resource. The embodiment of the application effectively integrates the ground network and satellite network communication. The base station can determine the distribution node of the requested resource according to the resource label. If the requested resource is not only distributed on the satellite node, but also distributed on the ground node, the base station preferentially obtains the resource from the ground node. Because the bandwidth and storage resource of the ground node are larger than those of the satellite node, the resource is preferentially obtained from the ground, which not only speeds up the resource obtaining speed, but also reduces the communication load pressure of the satellite.

[0101] In some embodiments, before step 304, the method further comprises: if the requested resource is only distributed on the satellite node, obtaining the requested resource from the satellite node.

[0102] In some embodiments, if the resource requester has the permission to access the requested resource, the base station can obtain the requested resource from the satellite node, i.e., the satellite node returns the requested resource. If the resource requester does not have the permission to access the requested resource, the base station can only obtain the message returned by the satellite node that denies the access, and cannot obtain the requested resource.

[0103] Based on the above embodiments, when the ground node does not have the requested resource, the satellite node is requested to provide the resource, which combines satellite communication and ground network communication, enriches the channel for users to obtain resources, and improves the user experience.

[0104] In some embodiments, if the requested resource is only distributed in the satellite node, the requested resource is obtained from the satellite node, including:

[0105] Determining the satellite node closest to the base station;

[0106] Obtaining the requested resource from the satellite node closest to the base station.

[0107] In some embodiments, the satellite node closest to the base station is a satellite node covering the base station. In theory, at least three satellites can realize global communication, i.e., satellite signals cover the global area except the two poles. In this embodiment, there are multiple satellite nodes, each satellite node covers a communication area, and the base station obtains the requested resource from the satellite node covering the area where the base station is located. It should be noted that the communication radius of a general 4G base station is 1-3 kilometers, and the communication range of a 5G base station is several hundred meters, and the area covered by satellite communication is much larger than the communication coverage range of the base station, so the position of the base station and the position of the resource requester can be regarded as the same position to determine the closest satellite node.

[0108] Based on the above embodiments, by obtaining the resource of the resource requester from the closest satellite node, the resource is not obtained from the satellite node covering other areas, which reduces the delay of ground and satellite communication and improves the speed of the user obtaining the resource from the satellite node.

[0109] In some embodiments, the step 303 includes determining the ground node closest to the base station, and obtaining the requested resource from the ground node closest to the base station.

[0110] In some embodiments, in a wired / wireless network coverage area, in order to improve the speed of users obtaining resources in the network, ground nodes are generally set in areas with high user density, and the number of base stations in the area is also larger compared to the user density. In this case, the user request can be directed to the nearest node by using global load technology, that is, obtaining resources from the node closest to the base station to improve the speed of users obtaining resources. In addition, the load of the node can also be considered, and the user request can be directed to the node with the smallest load within a certain range to avoid network congestion. Here, the node with the smallest load can be understood as the node with the least number of simultaneous resource requests.

[0111] Based on the above embodiments, by determining the node closest to the base station or the node with the smallest load, and obtaining resources from the node, the speed of users obtaining resources can be improved, the network delay can be reduced, and the user's network use experience can be improved.

[0112] Figure 4 An implementation flow diagram of a resource distribution method provided by the embodiments of the present application is applied to a first source station. As shown in Figure 2 The method can include steps 401 to 402, wherein:

[0113] Step 401, determining the distribution node of the to-be-distributed resource based on the label of the to-be-distributed resource.

[0114] Wherein, the label represents the security level and / or distribution range of the resource; the distribution node includes a ground node and / or a satellite node;

[0115] In some embodiments, the first source station is a resource provider, which can communicate directly with the node or communicate with the user through the base station or satellite network. It should be noted that the resource provider can be multiple objects providing resources, and the resource provider is not limited. Common resource providers include various video portals, websites, operators, etc. Here, they are collectively referred to as resource providers.

[0116] In some embodiments, the label is generated by the resource provider before distributing the resource, and the label is bound with the resource. The security level and range of the resource in the label can be determined based on the content of the resource, or can be set by the resource provider according to the actual situation and relevant regulations.

[0117] In some embodiments, based on the label of the to-be-distributed resource, it can be determined that the to-be-distributed resource can be distributed on the ground node or the satellite node, or on both nodes.

[0118] Based on the above embodiments, the distribution node of the to-be-distributed resource is determined based on the label of the resource before the resource distribution, the security and confidentiality of the resource are considered, and the resource of different security levels and / or distribution ranges is distributed to different nodes. In the case of ensuring that users can normally obtain the resource, the security of the resource distribution is improved.

[0119] In step 402, the to-be-distributed resource is distributed to the distribution node.

[0120] In some embodiments, only part of the resource can be distributed to the distribution node, for example, part of the resource with high popularity is preferentially distributed. Different resources can also be selected and distributed according to the characteristics of users in different regions, for example, a large number of old people in a certain region can preferentially distribute content of interest to the old people. Different resources can also be distributed according to different time periods, for example, traffic, weather and other information can be preferentially distributed in the morning or morning period, and entertainment messages can be preferentially distributed at night. The above is only an example of distributing resources, and the priority of resource distribution in the specific distribution process can be determined in combination with the actual situation. It should be noted that no matter in what way the preferentially distributed resource is determined, the resource distributed to the node will not exceed the range of the resource that should be distributed to the node, for example, the preferentially distributed resource in the satellite node will not be distributed to the ground node.

[0121] Based on the above embodiments, by setting a label for the resource and determining the distribution node of the resource based on the label, the distribution node of the resource can be limited, and the users who can access the resource are also limited, thereby improving the security in the resource distribution process. At the same time, the priority is set in the resource distribution, and in the case that the storage space of the node is limited, the use experience of the user is ensured, and the flexibility of the resource distribution is improved.

[0122] In some embodiments, step 402 includes: sending the to-be-distributed resource that needs to be distributed to the ground node to the second source station; and the ground node is used to obtain the to-be-distributed resource that needs to be distributed to the ground node from the second source station.

[0123] In some embodiments, the first source station can be a satellite ground station, and the second source station can be a content source station, wherein the first source station can communicate with the satellite node and distribute resources to the satellite node. The second source station can communicate with the ground node and distribute resources to the ground node. The resources in the first source station and the second source station can be different. The ground node obtains the to-be-distributed resources from the second source station, that is, the resources in the second source station are all to-be-distributed resources, and the second source station can distribute the resources in the station to the ground node. It should be noted that the first source station can also distribute resources to the ground node, but the distribution range is limited, and the bandwidth for satellite communication is occupied. Directly distributing resources to the second source station can directly request the second source station when some nodes need resources in the future, instead of requesting the first source station.

[0124] Based on the above embodiments, the first source station sends the to-be-distributed resources to the second source station, which expands the content range of the resources accessible by users, and saves satellite communication resources by distributing the to-be-distributed resources to the second source station. Ground communication with larger bandwidth is adopted to improve the efficiency of users obtaining resources.

[0125] In some embodiments, the method further comprises: receiving the to-be-distributed resources sent by the second source station to the satellite node;

[0126] Performing content legality verification on the to-be-distributed resources;

[0127] If the verification passes, the to-be-distributed resources are sent to the satellite node.

[0128] In some embodiments, the first source station is a satellite ground station, and after receiving the resources sent by the second source station, the first source station performs content legality verification on the resources, such as verifying the integrity of the resource content, auditing the content, etc. If the resource passes the verification, the to-be-distributed resources are sent to the satellite node. If the verification fails, the resource is abandoned, and information that the resource is illegal can be returned to the second source station.

[0129] Based on the above embodiments, the resources are verified by the satellite ground station before being distributed to the satellite node, which further ensures the safety of resource distribution, and the illegal resources are abandoned, avoiding the occupation of satellite node storage space by garbage information, and improving the utilization efficiency of the storage space.

[0130] Figure 5 An implementation flowchart of a resource distribution method provided by the embodiments of the present application is applied to a satellite node. As shown in Figure 5 The method can include steps 501 to 503, wherein:

[0131] Step 501, receiving a resource request.

[0132] In some embodiments, the resource request can be sent by a satellite terminal and / or an intranet / safely restricted network user in a restricted network area, or a resource request of a ground user forwarded by a base station, and the resource request is checked for authority, and the resource request is rejected if the resource request party does not have access authority of the resource.

[0133] In step 502, the resource requested by the resource request is acquired.

[0134] The resource in the satellite node is distributed to the satellite node by the first source station based on a label of the resource, which represents a security level and / or a distribution range of the resource.

[0135] In some embodiments, the resource requested by the resource request is acquired, which can be acquired locally from the satellite node, from a connected satellite node, from a satellite ground station (corresponding to the first source station), etc. Regardless of where the resource is acquired, the resource acquired by the satellite node is a resource allowed to be distributed to the satellite node based on the resource label by the satellite ground station or the content source station (corresponding to the second source station).

[0136] In some embodiments, only the security level of the resource distributed to the satellite node is higher than that of the resource distributed to the satellite node and the ground node at the same time, and the security level of the resource distributed only on the ground is the lowest. The distribution range of the resource distributed in the satellite node and the ground node at the same time is the largest.

[0137] In step 503, the requested resource is sent to the resource request party.

[0138] In some embodiments, when the resource request party is a satellite terminal and / or an intranet / safely restricted network user, the requested resource is directly sent to the resource request party; when the resource request party is a ground user, the resource is sent to the base station, which forwards the resource to the ground user.

[0139] Based on the above embodiments, the satellite node acquires resources for different user requests and adopts different resource sending modes, so that various users can acquire resources from the satellite node by establishing communication with the satellite, which expands the distribution range of the resources and improves the user experience.

[0140] In some embodiments, the step 502 includes determining whether the requested resource is stored locally in the satellite node; if the requested resource is not stored locally in the satellite node, the requested resource is acquired from a neighboring satellite node of the satellite node.

[0141] In some embodiments, when the satellite node receives a resource request and determines that the resource requester has the access right to the corresponding resource, it first determines whether the requested resource is stored locally. Since the resource storage space of the satellite node is limited, the satellite ground station does not upload all the resources to be distributed to the satellite node to the satellite node. Meanwhile, since the areas covered by different satellite nodes are different, the received resource requests can also be different, and the resources stored on each satellite node can also be different. Therefore, the satellite node needs to determine whether the requested resource is stored locally after receiving the resource request.

[0142] In some embodiments, if the requested resource is not stored locally on the satellite node, the satellite node acquires the requested resource from a satellite node adjacent to the satellite node. It should be noted that if the satellite node A receives a resource request but does not have the requested resource locally, the satellite node A can request resources from the satellite node B and the satellite node C adjacent to it. If the satellite node B and the satellite node C also do not have the requested resource, the satellite node B and the satellite node C can continue to acquire resources from adjacent satellite nodes. In this way, it can be determined whether the requested resource exists in all satellite nodes.

[0143] Based on the above embodiments, when the satellite node does not have the requested resource locally, the resource is acquired from an adjacent satellite. Direct communication between satellites is faster than communication with the ground network, and the user's requested resource can be quickly acquired and returned in time, thereby improving the speed of the user acquiring the resource from the satellite node.

[0144] In some embodiments, the method further includes: if the adjacent satellite node of the satellite node does not store the requested resource, acquiring the requested resource from a first source station.

[0145] In some embodiments, if the adjacent satellite node and other satellite nodes of the satellite node do not store the requested resource, the satellite node acquires the requested resource from a first source station. Here, the requested resource can be acquired from a satellite ground station. It should be noted that if the satellite ground station also does not have the requested resource, the satellite ground station can also acquire the requested resource from a content source station.

[0146] Based on the above embodiments, when the adjacent satellite node also does not have the requested resource, the resource is acquired from the ground in stages to achieve the fastest speed to acquire the resource and return it to the user.

[0147] In the following, an exemplary application of the embodiments of the present application in an actual application scenario will be described. Figure 6 An implementation flowchart of a resource distribution method provided by the embodiments of the present application is applied in a content source station, and the method includes steps S601 to S606, which will be described in combination with the steps shown in Figure 6 The method includes the following steps:

[0148] Step 601, the content source station distributes the resource.

[0149] In some embodiments, the content source station sets a corresponding label for the resource, which represents the security level and / or distribution range of the resource.

[0150] Step 602, whether to distribute to the satellite node.

[0151] Based on the label of the resource, it is determined whether the resource needs to be distributed to the satellite node. If not, step 603 is entered, and if yes, steps 604 and 603 are entered at the same time.

[0152] Step 603, inject the resource into the ground node.

[0153] In some embodiments, only part of the resource can be injected into the ground node, and other contents can be injected into the ground node in response to the corresponding resource request after obtaining the resource request.

[0154] Step 604, send the resource to the satellite ground station.

[0155] In some embodiments, the satellite ground station can perform legality verification on the received resource, and enter step 605 after the verification is passed.

[0156] Step 605, inject the resource verified by the satellite ground station into the satellite node.

[0157] In some embodiments, the satellite ground station can only inject part of the verified resource into the satellite node, and other resources can be stored locally in the satellite ground station, and sent to the satellite node when the satellite node requests the resource.

[0158] Figure 7 An implementation flow diagram of a resource distribution method provided by the embodiments of the present application is applied to a satellite ground station (corresponding to the first source station described above), and the method includes steps 701 to 705, which are described in combination with the steps shown in the figure. Figure 7 The method includes the following steps:

[0159] Step 701, the satellite ground station distributes the resource.

[0160] In some embodiments, the satellite ground station can perform verification on the distributed resource and set a corresponding label.

[0161] Step 702, whether to distribute to the ground node.

[0162] The satellite ground station determines whether the resource needs to be distributed to the ground node based on the label of the resource. If not, step 703 is entered, and if yes, steps 703 and 704 are entered at the same time.

[0163] Step 703, the satellite ground station injects the resource into the satellite node.

[0164] Step 704, the satellite ground station sends the resource to the content source station.

[0165] Step 705, the content source station injects the resource into the ground node.

[0166] Figure 8 An implementation flow diagram of a resource distribution method provided by an embodiment of the present application is shown, which comprises steps 801 to 819, which are described in combination with the steps shown in the figure. Figure 8 The method comprises the following steps:

[0167] Step 801, the ground user sends a resource request.

[0168] In some embodiments, the ground user sends a resource request to the base station, which forwards the request to the corresponding node.

[0169] Step 802, the wireless ground network covers or the limited user requests a resource.

[0170] Step 803, the base station determines whether the resource is only distributed in the satellite node.

[0171] If the resource requested by the ground user is not only distributed in the satellite node, go to step 804, and if the requested resource is only distributed in the satellite node, go to step 808.

[0172] Step 804, the base station forwards the resource request to the ground node in proximity according to the ground network area matching rule and the node scheduling rule.

[0173] In some embodiments, the base station can also forward the resource request to the ground node that currently responds to the request the least. The network area matching and node scheduling rules are rules for determining which node to forward the resource request of the ground user to based on the distance between the ground user and the surrounding nodes and the load status and network situation of the surrounding nodes.

[0174] Step 805, whether the ground node has the requested resource locally.

[0175] In some embodiments, when the ground node receives the resource request forwarded by the base station, it determines whether it has the requested resource locally, and if so, goes to step 807, and if not, goes to step 806.

[0176] Step 806, the ground node obtains the resource from the content source station, returns it to the ground user through the base station, and caches it locally.

[0177] In some embodiments, the resource can also be returned to the user directly by the content source station through the base station, while the requested resource is sent to the ground node, which caches the requested resource locally.

[0178] Step 807, the ground node returns the resource to the ground user through the base station.

[0179] Step 808, the user request is forwarded to the satellite node in proximity according to the user location information.

[0180] In some embodiments, for the ground user, the base station forwards the user request to the satellite node covering the current area based on the user's location information. For the user without network coverage or with limited access, the user can directly establish a connection with the satellite node covering the current area to request the resource.

[0181] Step 809, the satellite node checks whether the user has access to the resource.

[0182] After receiving the resource request of the user, the satellite node checks the access of the user. If the user has no access, it goes to step 810, and if the user has access, it goes to step 811.

[0183] Step 810, the user request is rejected.

[0184] The resource request of the user is rejected in the case that the user has no access to the resource, and the user can be returned the information of the rejection of the access.

[0185] Step 811, it is determined whether the satellite node has the resource cached locally.

[0186] Since the storage space of the satellite node is limited, the satellite ground station will not inject all the resources into the satellite node. Therefore, after receiving the resource request, the satellite node needs to confirm whether the requested resource is cached locally. If yes, it goes to step 812, and if no, it goes to step 813.

[0187] Step 812, the resource is returned to the user.

[0188] For the ground user, the satellite node returns the resource to the user through the base station. For the user without ground network coverage or with limited access (satellite terminal or internal / safe restricted network), the satellite node directly returns the resource to the user.

[0189] Step 813, whether the satellite node adjacent to the satellite node has the resource.

[0190] The satellite node adjacent to the satellite node also includes the satellite node adjacent to the adjacent satellite node, that is, the satellite node receiving the resource request queries whether the requested resource is in other satellite nodes. If yes, it goes to step 814, and if no, it goes to step 815.

[0191] Step 814, the adjacent satellite node returns the resource to the satellite node, and the satellite node returns the resource to the user and caches it locally.

[0192] The satellite node obtains the resource from other satellite nodes, and returns the resource to the user via the base station for a ground user. For a user without ground network coverage or a restricted user (satellite terminal or internal / safe restricted network), the satellite node directly returns the resource to the user and stores the resource locally.

[0193] Step 815, the satellite node requests the resource from the satellite ground station.

[0194] Step 816, whether the satellite ground station has the resource.

[0195] After receiving the resource request from the satellite node, the satellite ground station checks whether the requested resource is locally available. If yes, the process goes to step 818, and if not, the process goes to step 817.

[0196] Step 817, the satellite ground station obtains the resource from the content source station, returns the resource to the user via the base station or the satellite node, and caches the resource locally.

[0197] For a ground user, the content source station can directly return the resource to the user via the base station. For a user without ground network coverage or a restricted user, the satellite ground station returns the resource to the user via the satellite node and caches the resource locally.

[0198] Step 818, the satellite ground station injects the resource into the satellite node.

[0199] In step 817, the satellite ground station returns the resource to the user via the satellite node for a user without ground network coverage or a restricted user, and also injects the resource into the satellite node, i.e., stores the resource locally.

[0200] Step 819, the satellite ground station returns the resource to the user via the base station or the satellite node.

[0201] For a ground user, the satellite ground station returns the resource to the user via the base station. For a user without ground network coverage or a restricted user, the satellite ground station returns the resource to the user via the satellite node.
