[0032] FIG2 is a flow chart of a network function deployment method according to an embodiment of the present application, which can be applied to a low-orbit satellite communication system. As shown in FIG2 , the method includes the following steps:

[0033] Step S201: Obtain satellite resource utilization rate.

[0034] In the technical solution provided in the above step S201 of the present invention, the satellite resource utilization rate is obtained, wherein the satellite resource utilization rate is used to indicate the proportion of used satellite resources to the overall satellite resources. The satellite resource utilization rate can also be used to indicate the current usage of the overall satellite computing resources.

[0035] In this embodiment, the satellite resource utilization may be defined by the overall computable resources of the satellite constellation.

[0036] For example, the satellite resource utilization rate is defined based on the available computing resources of the entire satellite constellation. The satellite resource utilization rate r can be determined by the following formula: r = computing resource usage / (available computing resources × available computing time)

[0037] Here, r represents satellite resource utilization; available computing resources represents the total amount of available computing resources on the satellite; available computing time represents the time during which resources are available on the satellite within a certain time period; and computing resource utilization represents the total amount of computing resources already occupied on the satellite within a given time period. The time period can be one day, one week, or longer, without specific limitation.

[0038] In some embodiments of the present application, due to the limitation of limited computing resources on the satellite, the base stations of the network are usually deployed on the satellite in the initial stage, and the deployment of the network functions of the network can be dynamically adjusted according to the resource utilization rate on the satellite. Based on this, after obtaining the satellite resource utilization rate, the deployment information of the network functions of the network can be determined according to the satellite resource utilization rate and the satellite resource utilization rate threshold to determine whether the network functions of the network are deployed on the satellite or on the ground.

[0039] Step S202 : determining target deployment information of network functions of the network based on the satellite resource utilization rate and the satellite resource utilization rate threshold.

[0040] In the technical solution provided in step S202 of the present invention, after obtaining the satellite resource utilization rate in step S201, target deployment information of a network function of the network is determined based on the satellite resource utilization rate and the satellite resource utilization rate threshold, where the target deployment information is used to indicate satellite or terrestrial. The network function may also be referred to as a core network function.

[0041] In this embodiment, after obtaining the satellite resource utilization, the satellite resource utilization is compared with a satellite resource utilization threshold to obtain a comparison result, and target deployment information of the network function of the network is determined based on the comparison result. The satellite resource utilization threshold may include at least a minimum satellite computing resource usage (r_low) and a maximum satellite resource utilization (r_high). This is merely an example and does not limit the specific content of the satellite resource utilization threshold.

[0042] In some embodiments of the present application, the satellite resource utilization rate is compared with the maximum satellite resource utilization rate. If the satellite resource utilization rate is greater than the maximum satellite resource utilization rate, it means that the current satellite resource utilization rate is high, and the use of network base stations on the satellite should be prioritized. Therefore, it can be determined that the target deployment information of the network function of the network can be on the ground, that is, if the satellite carries core network computing resources at this time, the core network can be taken off the satellite and deployed with ground facilities.

[0043] For example, assuming that the satellite resource utilization rate is r and the maximum value of the satellite resource utilization rate is r_high, if r>r_high, it can be determined that the target deployment information is ground, that is, the target deployment location of the network function is ground.

[0044] In some embodiments of the present application, the utilization rate of satellite resources is compared with the minimum utilization rate of satellite resources. If the utilization rate of satellite resources is less than the minimum utilization rate of satellite resources, it indicates that the current utilization rate of satellite resources is relatively low. That is, there are more available computing resources on the satellite. In this case, the network functions of the network can be deployed on the satellite to utilize the satellite computing resources. Therefore, the target deployment information of the network functions of the network can be determined as the satellite.

[0045] For example, assume that the utilization rate of satellite resources is r and the lowest value of the utilization rate of satellite resources is r_low. If r < r_low, the target deployment information can be determined as the satellite. That is, the target deployment location of the network functions is the satellite.

[0046] Step S203, deploy the network functions of the network based on the target deployment information.

[0047] In the technical solution provided in step S203 of the present invention, after determining the target deployment information of the network functions of the network according to step S202, deploy the network functions of the network according to the target deployment information.

[0048] In this embodiment, after determining the target deployment information of the network functions of the network, the network functions of the network can be deployed on the satellite or on the ground according to the target deployment information.

[0049] For example, assume that the determined target deployment information of the network functions of the network is the ground. Then, it can be determined whether there are network functions deployed on the satellite at this time. If there are network functions deployed on the satellite at this time, the network functions on the satellite can be removed and the network functions can be deployed on the ground. Among them, the network functions can be core network functions.

[0050] In some embodiments of the present application, assume that the determined target deployment information of the network functions of the network is the satellite. Then, the network functions of the network can be deployed on the satellite. Among them, when deploying the network functions of the network on the satellite, since the network may include more than one network function, based on this, the priority of the network functions of the network can be calculated, and then the order of deploying the network functions on the satellite can be determined through the priority.

[0051] In some embodiments of the present application, the target deployment location of the network functions of the network can be dynamically adjusted according to the target deployment information, so as to maximize the utilization of network resources, achieve the purpose of effectively using network resources, and solve the technical problem of being unable to effectively use network resources.

[0052] It should be noted that the above embodiments can be executed by a network function deployment device of the network.

[0053] In the above steps S201 to S203 of the present invention, the target deployment information of the network function of the network can be determined based on the comparison result of the satellite resource utilization rate and the satellite resource utilization rate threshold, so as to deploy the network function of the network according to the target deployment information. Since the usage of satellite resources can be determined based on the satellite resource utilization rate, the target deployment information of the network function of the network can be dynamically adjusted, that is, the network function of the network is dynamically adjusted to be deployed on the satellite or on the ground, thereby achieving the purpose of dynamically reconstructing the deployment position of the network function of the network, thereby maximizing the utilization of network resources, thereby achieving the purpose of effectively utilizing network resources, and solving the technical problem of not being able to effectively utilize network resources.

[0054] The above method of this embodiment is further introduced below.

[0055] As an optional implementation method, step S202 determines the target deployment information of the network function of the network based on the satellite resource utilization rate and the satellite resource utilization rate threshold, including: comparing the satellite resource utilization rate with the maximum satellite resource utilization rate in the satellite resource utilization rate threshold to obtain a first comparison result; based on the first comparison result, determining the target deployment information of the network function of the network.

[0056] In this embodiment, the satellite resource utilization rate is compared with the maximum satellite resource utilization rate in the satellite resource utilization rate threshold to obtain a first comparison result. The maximum satellite resource utilization rate can be recorded as r_high. The first comparison result can be used to indicate whether the satellite resource utilization rate is higher than the maximum satellite resource utilization rate in the satellite resource utilization rate threshold.

[0057] In some embodiments of the present application, target deployment information of the network function of the network is determined according to the first comparison result.

[0058] For example, assuming that the satellite resource utilization rate is 80% and the maximum satellite resource utilization rate r_high is 70%, since 80%>70%, the first comparison result is that the satellite resource utilization rate is higher than the maximum satellite resource utilization rate r_high.

[0059] As an optional embodiment, based on the first comparison result, determining the target deployment information of the network function of the network includes: in response to the first comparison result being that the satellite resource utilization rate is higher than the maximum satellite resource utilization rate, determining that the target deployment information is ground.

[0060] In this embodiment, when the first comparison result shows that the satellite resource utilization rate is higher than the maximum satellite resource utilization rate, the target deployment information may be determined to be ground, that is, the core network functions are de-satelliteed and deployed on ground facilities.

[0061] For example, assuming that the first comparison result is that the satellite resource utilization rate is higher than the maximum satellite resource utilization rate r_high, it means that the current satellite computing resource utilization rate is high. In order to prioritize the use of network base stations on the satellite, the target deployment information of the network function can be determined as the ground.

[0062] As an optional embodiment, a network function deployment method of a network also includes: determining a current deployment location of the network function of the network; in response to the current deployment location of the network function being a satellite, removing the network function in the satellite; and deploying the network function on the ground.

[0063] In this embodiment, after determining that the target deployment information of the network function of the network is terrestrial, the current deployment location of the network function of the network can be further determined. When the current deployment location of the network function is a satellite, the network base station on the satellite must be prioritized. In this case, the network function in the satellite can be removed, thereby deploying the network function on the ground.

[0064] In some embodiments of the present application, network functions are deployed according to target deployment information. By dynamically adjusting the deployment locations of network functions in the network, the function of dynamically reconstructing the deployment locations of network functions in the network can be achieved, thereby maximizing the utilization of network resources.

[0065] As an optional implementation method, step S202 determines the target deployment information of the network function of the network based on the satellite resource utilization rate and the satellite resource utilization rate threshold, including: comparing the satellite resource utilization rate with the minimum satellite resource utilization rate in the satellite resource utilization rate threshold to obtain a second comparison result; based on the second comparison result, determining the target deployment information of the network function of the network.

[0066] In this embodiment, the satellite resource utilization rate is compared with the minimum satellite resource utilization rate in the satellite resource utilization rate threshold to obtain a second comparison result. The minimum satellite resource utilization rate can be recorded as r_low. The second comparison result can be used to indicate whether the satellite resource utilization rate is lower than the minimum satellite resource utilization rate in the satellite resource utilization rate threshold.

[0067] In some embodiments of the present application, target deployment information of the network function of the network is determined according to the second comparison result.

[0068] For example, assuming that the satellite resource utilization rate is 20% and the minimum satellite resource utilization rate r_low is 30%, since 20%<30%, the second comparison result is that the satellite resource utilization rate is lower than the minimum satellite resource utilization rate r_low.

[0069] As an optional embodiment, based on the second comparison result, determining the target deployment information of the network function of the network includes: in response to the second comparison result being that the computing resource utilization rate is lower than the minimum satellite resource utilization rate, determining the target deployment information to be a satellite.

[0070] In this embodiment, when the second comparison result is that the satellite resource utilization rate is lower than the minimum satellite resource utilization rate, the target deployment information can be determined to be a satellite, that is, the network functions of the network can be deployed on the satellite.

[0071] For example, assuming that the second comparison result is that the satellite resource utilization rate is lower than the maximum satellite resource utilization rate r_low, it means that the satellite's computing resource utilization rate is low. In this case, the target deployment information of the network function of the network can be determined as the satellite, and then the network function of the network can be deployed on the satellite.

[0072] As an optional implementation method, a network function deployment method for a network also includes: determining a network function set corresponding to the network function of the network, wherein the network function set includes at least one network function of the network; calculating the satellite resource utilization rate and network delay parameters corresponding to the at least one network function when the at least one network function is deployed on a satellite; in response to the satellite resource utilization rate corresponding to the network function being lower than the maximum satellite resource utilization rate, determining the priority corresponding to the at least one network function based on the satellite resource utilization rate and the network delay parameters corresponding to the network function; and in response to the priority corresponding to the network function being the largest, deploying the network function on the satellite.

[0073] In this embodiment, after determining that the target deployment information of the network function of the network is ground, the network function set corresponding to the network function of the network can be further determined, wherein the network function set can include multiple network functions, and the network function set can also be called a core network function combination set.

[0074] For example, the network function combination set can be c = {c1, c2, c3...cn}, where c1 to cn respectively represent the core network network function combination, for example: c1 is defined as the authentication management function (Authentication Management Function, abbreviated as AMF), c2 is the authentication management function and user plane data network (Authentication Management Function and User Data Management, abbreviated as AMF+UDM), session management function (Session Management Function, abbreviated as SMF), user plane function (User Plane Function, abbreviated as UPF), etc. This is only an illustrative example and does not limit the core network functions included in the network function combination set.

[0075] In some embodiments of the present application, when the target deployment location of a network function is determined to be a satellite, the corresponding satellite resource utilization rate and network delay parameter for each network function in the network function set when deployed on the satellite can be calculated. The satellite resource utilization rate can be represented by r, and the network delay parameter can be represented by δ. The network delay parameter can be used to represent satellite network delay, for example, the delay from random access to final bearer establishment.

[0076] In some embodiments of the present application, after determining the corresponding satellite resource utilization rate r of each network function in the network function set when deployed on a satellite, the satellite resource utilization rate of each network function can be compared with the maximum satellite resource utilization rate r_high. In response to the satellite resource utilization rate r corresponding to a certain network function being greater than the maximum satellite resource utilization rate r_high, the network function can be deleted from the network function set, thereby obtaining a target network function set, wherein the satellite resource utilization rate of each network included in the target network function set is less than the satellite resource utilization rate threshold. The priority of each network function in the target network function set can be determined based on the satellite resource utilization rate and network delay parameter corresponding to each network function included in the target network function set, and the network function with the highest priority is determined as the target network function, and the target network function is deployed on the satellite.

[0077] For example, the core network function combination set {c1, c2, c3…cn} is traversed sequentially. For each of c1 to cn satellite access scenario, r and δ are calculated for each of them. A priority set is then calculated based on r and δ. Each priority in the priority set represents the satellite access priority of the corresponding network function. The priority set can be {Δ1, Δ2, Δ3…Δn}, where Δn = w_1*r+w_2 / δ. Δn represents the priority of the nth network function, w_1 represents the weight of the computing resource utilization r, and w_2 represents the weight of the network delay parameter δ. After determining the priorities of each network function, the comprehensive priority set {Δ1, Δ2, Δ3…Δn} is traversed. If the core network function combination corresponding to an element in the set results in computing resource utilization r > r_high, the element is removed from the set. After the traversal is complete, a new comprehensive priority set {Δ1, Δ2, Δ3…Δn'} is obtained, where n' ≤ n.

[0078] In some embodiments of the present application, when the priority corresponding to the network function is the highest, the network function is deployed on the satellite.

[0079] For example, the maximum value in the new comprehensive priority set {Δ1, Δ2, Δ3…Δn'} is selected, the core network function corresponding to the maximum value is found, and the core network function is deployed on the satellite.

[0080] It should be noted that the above embodiments can be executed by a network function deployment device of a network.

[0081] In this embodiment, the target deployment information of the network function of the network can be determined based on the comparison result of the satellite resource utilization rate and the satellite resource utilization rate threshold, so that the network function of the network can be deployed according to the target deployment information. Since the usage of satellite resources can be determined based on the satellite resource utilization rate, the target deployment information of the network function of the network can be dynamically adjusted, that is, the network function of the network is dynamically adjusted to be deployed on the satellite or on the ground, thereby achieving the purpose of dynamically reconstructing the deployment position of the network function of the network, thereby maximizing the utilization of network resources, thereby achieving the purpose of effectively utilizing network resources, and solving the technical problem of not being able to effectively utilize network resources.

[0082] The following further introduces an efficient and intensive dynamic reconfiguration satellite-ground fusion network architecture design according to an embodiment of the present invention.

[0083] FIG3 is a flow chart of a method for designing an efficient and intensive dynamic reconstruction satellite-ground fusion network architecture according to an embodiment of the present invention. As shown in FIG3 , the method may include the following steps:

[0084] Step S301, define the computing resource utilization rate, the set of core network function combinations, and the network delay parameter.

[0085] In this embodiment, based on the overall available computing resources of the satellite constellation, the computing resource utilization rate is defined. The computing resource utilization rate can be represented by r: r = amount of occupied computing resources / (available computing resources × available computing time)

[0086] Among them, r can be used to represent the satellite resource utilization rate; available computing resources can be used to represent the total amount of available computing resources on the satellite; available computing time can be used to represent the time when resources are available within a certain time period on the satellite; the amount of occupied computing resources can be used to represent the sum of the occupied computing resources on the satellite within a given time period. Among them, the time period can be 1 day, 1 week, or a longer time, and no specific limitation is made here.

[0087] In some embodiments of the present application, define the set of core network function combinations c = {c1, c2, c3... cn}, where c1 to cn respectively represent the core network function combinations. For example: define c1 as AMF, c2 as AMF + UDM, etc. No limitation is made on the core network function combinations here.

[0088] Define the network delay parameter, which can be represented by δ and is used to indicate the core concerned delay of the satellite communication network. For example: the network delay parameter can be defined as the delay from the user's random access to the completion of the final bearer establishment.

[0089] In some embodiments of the present application, for the low-earth orbit satellite communication system, considering the limited on-board computing resources, therefore, in the initial stage, a network architecture strategy of deploying the base station on the satellite and centrally deploying the core network on the ground is adopted.

[0090] Step S302, judge the resource utilization rate.

[0091] In this embodiment, judge whether the resource utilization rate is greater than the highest value of the resource utilization rate, or whether the resource utilization rate is less than the lowest value of the resource utilization rate. If the resource utilization rate is less than the lowest value of the resource utilization rate, that is, r < r_low, then execute step S304. If the resource utilization rate is greater than the highest value of the resource utilization rate, that is, r > r_high, then execute step S303.

[0092] Step S303, unload the on-board core network function.

[0093] In this embodiment, unload the on-board core network function.

[0094] In some embodiments of the present application, since the resource utilization rate is greater than the maximum resource utilization rate, it is determined that the computing resource utilization rate r of the satellite constellation is higher and should be prioritized for base station use. If the satellite is carrying core network computing resources at this time, the core network functions on the satellite are offloaded and deployed on the ground.

[0095] Step S304: The core network functions are sequentially added to the satellite.

[0096] In this embodiment, core network functions are sequentially added to the satellite.

[0097] In some embodiments of the present application, since the resource utilization rate is less than the minimum value of the resource utilization rate, it is determined that the computing resource utilization rate r of the satellite constellation is low, and the core network functions are sequentially launched into the satellite.

[0098] Step S305: Calculate resource utilization and network delay parameters after the core network function combination is put on the satellite.

[0099] In this embodiment, after each core network function combination in the core network function combination set is launched into satellite according to step S304, the resource utilization and network delay parameters of each core network function combination in the core network function combination set after launching into satellite are calculated respectively.

[0100] Step S306: Determine the difference between the resource utilization of the core network function combination and the maximum resource utilization.

[0101] In this embodiment, it is determined whether the resource utilization of the core network function combination is less than the maximum resource utilization r_high. If the resource utilization of the core network function combination is less than the maximum resource utilization, step S308 is executed; if the resource utilization of the core network function combination is greater than the maximum resource utilization, step S307 is executed.

[0102] Step S307: traverse the next core network function combination.

[0103] In this embodiment, the next core network function combination in the core network function combination set is traversed.

[0104] Step S308: Calculate the comprehensive priority and obtain a new set.

[0105] In this embodiment, the comprehensive priority of each core network function combination in the core network function combination set is calculated to obtain a new set.

[0106] In some embodiments of the present application, the core network function combination set is sequentially traversed, and the core network function combination set can be: {c1, c2, c3...cn}. When c1-cn are on the satellite, r and δ are calculated, and a comprehensive priority is calculated based on r and δ. The comprehensive priority can be: {Δ1, Δ2, Δ3...Δn}, where Δn = w_1*r+w_2 / δ. Where w_1 represents the weight of the calculation resource utilization r, and w_2 represents the weight of the network delay parameter δ.

[0107] In some embodiments of the present application, the set of comprehensive priorities {Δ1, Δ2, Δ3…Δn} is traversed. If the core network function combination corresponding to an element in the set results in a computing resource utilization rate r>r_high, the element is deleted from the set. After the traversal is completed, a new set of comprehensive priorities {Δ1, Δ2, Δ3…Δn'} is obtained, where n'≤n.

[0108] Step S309: determine whether the comprehensive priority set is empty.

[0109] In this embodiment, it is determined whether the new comprehensive priority set {Δ1, Δ2, Δ3 . . . Δn'} is empty. If it is empty, it means that there is no core network function combination that meets the conditions, and step S310 is executed. If it is not empty, step S311 is executed.

[0110] Step S310: Keep the network architecture unchanged.

[0111] In this embodiment, the network architecture remains unchanged.

[0112] Step S311: Select the core network function combination corresponding to the maximum value in the set, launch it to the satellite, and reconstruct the network architecture.

[0113] In this embodiment, the maximum value in the new comprehensive priority set {Δ1, Δ2, Δ3…Δn'} is selected to find the corresponding core network function combination, which can be recorded as c_target. c_target is selected to be launched and the network architecture is reconstructed.

[0114] An efficient and intensive method for designing a dynamic reconstruction satellite-ground fusion network architecture according to an embodiment of the present invention is described below by way of example.

[0115] Assume that for a low-orbit satellite broadband mobile communication system with 300 satellites, the initial base stations are set up on the satellites and the core network is centrally deployed on the ground.

[0116] In some embodiments of the present application, r_low=30%, r_high=70%, weights w_1=1, w_2=1000, and the core network function combination set is {AMF, AMF+UDM, AMF+UDM+SMF, AMF+UDM+UPF}.

[0117] In some embodiments of the present application, after setting a scenario where the core network is centrally deployed on the ground, the resource utilization r is calculated. When the satellite constellation calculated resource utilization r is less than 30%, the core network function is triggered to go online.

[0118] In some embodiments of the present application, after triggering the core network function to go online, the set {AMF, AMF+UDM, AMF+UDM+SMF, AMF+UDM+UPF} is traversed, and r and δ are calculated respectively to obtain the comprehensive priority Δ=1*r+1000 / δ corresponding to each core network function combination.

[0119] In some embodiments of the present application, after obtaining the comprehensive priority corresponding to each core network function combination, the comprehensive priorities of each combination are compared, the maximum value is selected, and the corresponding core network function combination is found. Assuming that the evaluation results are AMF+UDM, AMF+UDM is deployed to the satellite and the network architecture is reconstructed.

[0120] In some embodiments of the present application, after a period of time after the network architecture is reconstructed, the base station computing load increases, triggering the satellite constellation computing resource utilization rate r>70%, then the AMF+UDM function is re-placed on the ground deployment and the network architecture is reconstructed.
