[0030] Figure 2 FIG. 1 is a flow chart of a network function deployment method of a network according to an embodiment of the present application, which can be applied to a low-orbit satellite communication system. Figure 2 As shown, the method comprises the following steps:

[0031] Step S201, obtaining satellite resource utilization rate.

[0032] 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, and the satellite resource utilization rate can also be used to indicate the usage of the current overall satellite computing resources.

[0033] In this embodiment, the satellite resource utilization may be defined by the overall computable resources of the satellite constellation.

[0034] For example, the satellite resource utilization rate is defined based on the overall available computing resources of the satellite constellation. The satellite resource utilization rate r can be determined by the following formula:

[0035] r = computing resource usage / (available computing resources × available computing time)

[0036] Among them, r can be used to represent the satellite resource utilization rate; available computing resources can be used to represent the sum of available computing resources on the satellite; available computing time can be used to represent the time when resources are available on the satellite within a certain time period; computing resource usage can be used to represent the sum of computing resources already occupied on the satellite within a given time period. Among them, the time period can be 1 day, 1 week or longer, and there is no specific limitation here.

[0037] Optionally, 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.

[0038] 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.

[0039] In the technical solution provided in the above step S202 of the present invention, after obtaining the satellite resource utilization rate in step S201, the target deployment information of the network function of the network is determined according to the satellite resource utilization rate and the satellite resource utilization rate threshold, wherein the target deployment information is used to represent the satellite or the ground. The network function may also be referred to as a core network function.

[0040] In this embodiment, after obtaining the satellite resource utilization rate, the satellite resource utilization rate is compared with the satellite resource utilization rate threshold to obtain a comparison result, and then the target deployment information of the network function of the network is determined according to the comparison result. Among them, the satellite resource utilization rate threshold can at least include the minimum satellite computing resource usage (r_low) and the maximum satellite resource utilization rate (r_high). This is only an exemplary example and does not limit the specific content of the satellite resource utilization rate threshold.

[0041] Optionally, compare the satellite resource utilization rate 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 relatively high, and the use of the network base station 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 the ground. That is, if the core network computing resources are carried on the satellite at this time, the core network can be moved down to the satellite and deployed with the ground facilities.

[0042] For example, assume that the satellite resource utilization rate is r and the highest value of the satellite resource utilization rate is r_high. If r > r_high, the target deployment information can be determined as the ground, that is, the target deployment location of the network function is the ground.

[0043] Optionally, compare the satellite resource utilization rate with the minimum satellite resource utilization rate. If the satellite resource utilization rate is less than the minimum satellite resource utilization rate, it means that the current satellite resource utilization rate is relatively low, that is, there are more available computing resources on the satellite. In this case, the network function of the network can be deployed on the satellite to utilize the satellite computing resources. Therefore, it can be determined that the target deployment information of the network function of the network is the satellite.

[0044] For example, assume that the satellite resource utilization rate is r and the lowest value of the satellite resource utilization rate 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 function is the satellite.

[0045] Step S203, deploy the network function of the network based on the target deployment information.

[0046] In the technical solution provided in step S203 of the present invention above, after determining the target deployment information of the network function of the network according to step S202, deploy the network function of the network according to the target deployment information.

[0047] In this embodiment, after determining the target deployment information of the network function of the network, the network function of the network can be deployed on the satellite or the ground according to the target deployment information.

[0048] For example, assuming that the target deployment information of the network function of the determined network is the ground, it can be determined whether the network function is deployed on the satellite at this time. If the network function is deployed on the satellite at this time, the network function on the satellite can be removed and deployed on the ground. The network function can be a core network function.

[0049] Optionally, assuming that the target deployment information of the network function of the determined network is a satellite, the network function of the network can be deployed on the satellite. When the network function of the network is deployed on the satellite, since the network may contain more than one network function, based on this, the priority of the network function of the network can be calculated, and then the order of deploying the network functions on the satellite can be determined by the priority.

[0050] Optionally, the target deployment position of the network function of the network can be dynamically adjusted according to the target deployment information, so as to maximize the utilization of network resources and achieve the purpose of effectively utilizing network resources, thus solving the technical problem of not being able to effectively utilize network resources.

[0051] It should be noted that the above embodiments can be executed by a network function deployment device of a network.

[0052] 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 according to 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 according to 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 the ground, thereby achieving the purpose of dynamically reconstructing the deployment position of the network function of the network, so as to maximize 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.

[0053] The above method of this embodiment is further introduced below.

[0054] 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.

[0055] 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.

[0056] Optionally, according to the first comparison result, target deployment information of the network function of the network is determined.

[0057] 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.

[0058] As an optional implementation method, 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.

[0059] In this embodiment, when the first comparison result is that the satellite resource utilization rate is higher than the maximum satellite resource utilization rate, the target deployment information can be determined to be ground, that is, the core network function is de-satelliteed and deployed on ground facilities.

[0060] 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 give priority to the use of network base stations on the satellite, the target deployment information of the network function of the network can be determined as the ground.

[0061] As an optional implementation method, a network function deployment method for 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.

[0062] In this embodiment, after determining that the target deployment information of the network function of the network is the ground, 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, since the use of the network base station on the satellite must be prioritized, in this case, the network function in the satellite can be removed, so that the network function is deployed on the ground.

[0063] Optionally, by deploying network functions according to target deployment information, the deployment positions of network functions in the network can be dynamically adjusted to achieve the function of dynamically reconstructing the deployment positions of network functions in the network, thereby maximizing the utilization of network resources.

[0064] 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.

[0065] 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.

[0066] Optionally, according to the second comparison result, target deployment information of the network function of the network is determined.

[0067] 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.

[0068] As an optional implementation manner, 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 is lower than the minimum satellite resource utilization, determining the target deployment information to be a satellite.

[0069] 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 function of the network can be deployed on the satellite.

[0070] 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.

[0071] As an optional implementation manner, 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 parameter corresponding to the at least one network function when the at least one network function is deployed on the 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 parameter corresponding to the network function; in response to the priority corresponding to the network function being the largest, deploying the network function on the satellite.

[0072] 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 may include multiple network functions, and the network function set may also be called a core network function combination set.

[0073] 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 authentication management function (Authentication Management Function, abbreviated as AMF), c2 is 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.

[0074] Optionally, when it is determined that the target deployment location of the network function is a satellite, the corresponding satellite resource utilization rate and network delay parameter of each network function in the network function set when deployed on the satellite can be calculated respectively. The satellite resource utilization rate can be represented by r, and the network delay parameter can be represented by δ, wherein the network delay parameter can be used to represent the satellite network delay, for example, the delay from random access of the user to the completion of the final bearer establishment.

[0075] Optionally, after determining the corresponding satellite resource utilization rate r of each network function in the network function set when it is deployed on the 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> 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 rates of each network included in the target network function set are all 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 parameters corresponding to each network function included in the target network function set, thereby determining the network function with the highest priority as the target network function, and deploying the target network function on the satellite.

[0076] For example, the core network function combination set is traversed in sequence, and the core network function combination set can be: {c1, c2, c3...cn}. When c1~cn are on the satellite, the corresponding r and δ are calculated, and the priority set is calculated based on r and δ. Each priority in the priority set is the satellite priority corresponding to the corresponding network function. The priority set can be: {Δ1, Δ2, Δ3...Δn}, where Δn=w_1*r+w_2 / δ. Among them, Δn can be used to represent the priority corresponding to the nth network function, w_1 can be used to represent the weight of the computing resource utilization r, and w_2 can be used to represent the weight of the network delay parameter δ. After determining the priority corresponding to each network function, the comprehensive priority set {Δ1, Δ2, Δ3...Δn} can be traversed. If the core network function combination corresponding to the element in the set makes the computing resource utilization r>r_high, then the element is deleted from the set. After the traversal is completed, a new comprehensive priority set {Δ1, Δ2, Δ3...Δn'} is obtained, n'≤n.

[0077] Optionally, when the priority corresponding to the network function is the highest, the network function is deployed on the satellite.

[0078] 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.

[0079] It should be noted that the above embodiments can be executed by a network function deployment device of a network.

[0080] In this embodiment, the target deployment information of the network function of the network can be determined according to 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 according to 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 the ground, thereby achieving the purpose of dynamically reconstructing the deployment position of the network function of the network, so that the network resources can be maximized, thereby achieving the purpose of effectively utilizing the network resources, and solving the technical problem of not being able to effectively utilize the network resources.

[0081] The following is a further introduction to an efficient and intensive dynamic reconfiguration satellite-ground fusion network architecture design according to an embodiment of the present invention.

[0082] Figure 3 is a flow chart of an efficient and intensive method for designing a dynamic reconstruction satellite-ground fusion network architecture according to an embodiment of the present invention. Figure 3 As shown, the method may include the following steps:

[0083] Step S301, defining computing resource utilization, core network function combination set and network delay parameters.

[0084] In this embodiment, based on the overall available computing resources of the satellite constellation, a computing resource utilization is defined, which can be represented by r:

[0085] r = computing resource usage / (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 sum of available computing resources on the satellite; available computing time can be used to represent the time when resources are available on the satellite within a certain time period; computing resource usage can be used to represent the sum of computing resources already occupied on the satellite within a given time period. Among them, the time period can be 1 day, 1 week or longer, and there is no specific limitation here.

[0087] Optionally, a core network function combination set c = {c1, c2, c3…cn} is defined, where c1 to cn represent core network network function combinations respectively. For example, c1 is defined as AMF, c2 is defined as AMF+UDM, etc. There is no restriction on the core network network function combination here.

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

[0089] Optionally, for a low-Earth orbit satellite communication system, considering the limited on-board computing resources, 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, determine the resource utilization rate.

[0091] In this embodiment, it is determined whether the resource utilization rate is greater than the maximum value of the resource utilization rate or less than the minimum value of the resource utilization rate. If the resource utilization rate is less than the minimum value of the resource utilization rate, that is, r < r_low, then step S304 is executed. If the resource utilization rate is greater than the maximum value of the resource utilization rate, that is, r > r_high, then step S303 is executed.

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

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

[0094] Optionally, since the resource utilization rate is greater than the maximum value of the resource utilization rate, it is determined that the computing resource utilization rate r of the satellite constellation is relatively high, and the base station should be given priority. If the on-board core network computing resources are carried at this time, the on-board core network function is offloaded and deployed on ground facilities.

[0095] Step S304, successively upload the core network functions to the satellite.

[0096] In this embodiment, the core network functions are successively uploaded to the satellite.

[0097] Optionally, 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 relatively low, and thus the core network functions are successively uploaded to the satellite.

[0098] Step S305, calculate the resource utilization rate and network delay parameters after the core network function combination is uploaded to the satellite.

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

[0100] Step S306, determine the size relationship between the resource utilization rate of the core network function combination and the maximum value of the resource utilization rate.

[0101] In this embodiment, it is determined whether the resource utilization rate of the core network function combination is less than the maximum value r_high of the resource utilization rate. If the resource utilization rate of the core network function combination is less than the maximum value of the resource utilization rate, then step S308 is executed. If the resource utilization rate of the core network function combination is greater than the maximum value of the resource utilization rate, then 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, calculating the comprehensive priority to 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] Optionally, the core network function combination set is traversed in sequence, and the core network function combination set can be: {c1, c2, c3...cn}, and r and δ are calculated when c1~cn are on the satellite, and the comprehensive priority is calculated based on r and δ. The comprehensive priority can be: {Δ1, Δ2, Δ3...Δn}, Δn=w_1*r+w_2 / δ. Among them, w_1 represents the weight of the calculation resource utilization r, and w_2 represents the weight of the network delay parameter δ.

[0107] Optionally, the set of comprehensive priorities {Δ1, Δ2, Δ3 ... Δn} is traversed, and if the core network function combination corresponding to the element in the set makes the computing resource utilization 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, determining 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, keeping 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, carry out satellite launch, 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 example of an efficient and intensive method for designing a dynamic reconstruction satellite-ground fusion network architecture according to an embodiment of the present invention is given below.

[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] Optionally, set 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] Optionally, after setting a scenario where the core network is centrally deployed on the ground, the resource utilization r is calculated, and when the satellite constellation calculates that the resource utilization r is less than 30%, the core network function is triggered to go online.

[0118] Optionally, after triggering the core network function to go online, traverse the set {AMF, AMF+UDM, AMF+UDM+SMF, AMF+UDM+UPF}, calculate r and δ respectively, and obtain the comprehensive priority Δ=1*r+1000 / δ corresponding to each core network function combination.

[0119] Optionally, after obtaining the comprehensive priority corresponding to each core network function combination, compare the comprehensive priorities under each combination, select the maximum value, and find the corresponding core network function combination, assuming that it is AMF+UDM after evaluation. Then AMF+UDM is put on the satellite and the network architecture is reconstructed.

[0120] Optionally, after a period of time of reconstructing the network architecture, the computing workload of the base station increases, triggering the satellite constellation computing resource utilization r>70%, then the AMF+UDM function is re-placed on the ground for deployment and the network architecture is reconstructed.
