Among them, the computing power request identifier is used to indicate whether it is necessary to establish a computing power session. For example, if the computing power request identifier is "0", it means that it is not necessary to establish a computing power session. If the computing power request identifier is "1", it means that it is necessary to establish a computing power session. On this basis, in this embodiment, in response to a computing power session establishment request carrying computing power session information initiated by a user terminal, an optional implementation method of sending a policy acquisition request to a PCF network element is to respond to a computing power session establishment request carrying computing power session information initiated by a user terminal, and send a policy acquisition request to a PCF network element when the computing power request identifier indicates that a computing power session needs to be established.

[0118] S402, based on the initial computing power routing strategy, after controlling the user terminal to establish a computing power session relationship with the anchor UFP network element, sends computing power session information to the computing power policy control function CPCF network element.

[0119] Optionally, in this embodiment, the SMF network element controls the user terminal to establish a computing power session relationship with the anchor UFP network element based on the initial computing power routing strategy, and then sends computing power session information to the computing power policy control function CPCF network element. That is to say, before sending the computing power session information to the computing power policy control function CPCF network element, the user terminal has established a computing power session relationship with the anchor UFP network element.

[0120] In this embodiment, in response to a computing power session establishment request initiated by a user terminal and carrying computing power session information, a policy acquisition request is sent to the PCF network element, and the PCF network element feeds back the initial computing power routing policy to the SMF network element based on the policy acquisition request. Based on the initial computing power routing policy, the user terminal is controlled to establish a computing power session relationship with the anchor UFP network element, and while the computing power session relationship is established, the computing power session information is sent to the computing power policy control function CPCF network element. In this embodiment, a prerequisite for sending computing power session information to the computing power policy control function CPCF network element is added, that is, after the user terminal establishes a computing power session relationship with the anchor UFP network element, the computing power session information is sent to the computing power policy control function CPCF network element.

[0121] On the basis of the above embodiments, in order to realize the flexible modification of computing power session relationship and improve the timeliness of computing power business services, Figure 5 As shown, the optional implementation method of providing computing power services to user terminals through target computing power nodes based on the target computing power routing strategy in S202 includes:

[0122] S501, based on the target computing power routing strategy, controls the computing power session relationship of the user terminal to be redirected to the relay UPF network element associated with the target computing power node.

[0123] Based on the above embodiments, it can be known that the user terminal establishes a computing power session relationship with the anchor UFP network element in advance. When the target computing power routing policy is received, it means that the edge computing power node can meet the requirements of the user terminal to provide computing power services. In other words, when the SMF network element receives the target computing power routing policy, it can control the user terminal's computing power session relationship to redirect to the relay UPF network element associated with the target computing power node based on the target computing power routing policy, so that the user terminal establishes a computing power session relationship with the relay UPF network element associated with the target computing power node.

[0124] S502: When the computing power session relationship is redirected successfully, computing power services are provided to the user terminal through the target computing power node.

[0125] In this embodiment, based on the target computing power routing policy, the computing power session relationship of the user terminal is controlled to be redirected to the relay UPF network element associated with the target computing power node. When the computing power session relationship is redirected successfully, computing power services are provided to the user terminal through the target computing power node. Based on this embodiment, when the SMF network element receives the target computing power routing policy, it can complete the redirection of the computing power session relationship based on the target computing power routing policy, and the edge computing power node provides computing power services to the user terminal. The service is more timely and the computing power burden of the remote computing power node is reduced. It should be noted that if the SMF network element does not receive the target computing power routing policy, it means that the edge computing power node cannot meet the computing power service requirements of the user terminal. Since the user terminal has established a computing power session relationship with the remote computing power node in advance, the remote computing power node can subsequently provide computing power services to the user terminal.

[0126] In one embodiment, Figure 6 is a flowchart of a computing power service method provided according to an embodiment of the present application, in which the method is applied to Figure 1 Taking the CPCF network element in FIG. 1 as an example, the method includes the following steps:

[0127] S601, receive computing power session information sent by the SMF network element, and select a target computing power node from the candidate computing power nodes based on the computing power session information and the computing power status information of the candidate computing power nodes.

[0128] Among them, the computing power session information is carried in the computing power session establishment request initiated by the user terminal to the SMF network element. The computing power session information refers to the demand information of the computing power session, including but not limited to the computing power demand type, computing power demand size and maximum tolerance time. Among them, the computing power demand type refers to the type of computing power resources required by the user terminal, such as the computing power resources required by various AI applications, and the computing power resources required by AR, VR and other services. The computing power demand size refers to the number of required computing power units. The computing power unit refers to the smallest unit of computing power service. The maximum tolerance time refers to the maximum waiting time that can be tolerated by the computing power service. In addition, the computing power session information also includes terminal identification, application identification, etc. The terminal identification refers to the unique identification of the user terminal, which can be the terminal IP address or terminal ID. The application identification refers to the identification of the business application corresponding to the computing power service, for example, the application program identification. The computing power status information refers to the computing power status information of the computing power service server, including but not limited to the computing power resource information provided, the number of available computing power units and the computing power node identification. In addition, it can also include the node port of the computing power node.

[0129] As an optional implementation of the embodiment of the present application, the CPCF network element selects a target computing power node from the candidate computing power nodes based on the computing power session information and the computing power status information of the candidate computing power nodes. An optional implementation is that the CPCF network element matches the computing power status information of the candidate computing power nodes according to the computing power session information, and uses the candidate computing power node that successfully matches the computing power session information with the computing power status information as the target computing power node.

[0130] As another optional implementation of the embodiment of the present application, a target computing node is selected from candidate computing nodes based on computing session information and computing status information of the candidate computing nodes through an intelligent computing power allocation model. Specifically, the computing session information and the computing status information of the candidate computing nodes are input into the intelligent computing power allocation model, and the intelligent computing power allocation model outputs the target computing node.

[0131] S602, based on the node type of the target computing power node, generate a computing power routing strategy.

[0132] Among them, the node type refers to the node type of the target computing power node. In this application, the candidate computing power nodes include the edge computing power nodes associated with the relay UPF network element and the remote computing power nodes associated with the anchor UFP network element. The anchor UPF network element is the UPF network element connected to the data network, and the data network is connected to the remote computing power node. In other words, the node type of the target computing power node is an edge computing power node or a remote computing power node.

[0133] Optionally, an optional implementation of this embodiment is that if the node type of the target computing power node is an edge computing power node, a computing power routing strategy is generated.

[0134] Optionally, another optional implementation of this embodiment is that if the node type of the target computing power node is a remote computing power node, the computing power routing strategy is not generated. In this embodiment, before executing the generation process of the computing power routing strategy based on the node type of the target computing power node, the following steps need to be performed: in response to the computing power session establishment request initiated by the user terminal and carrying the computing power session information, a policy acquisition request is sent to the PCF network element, so that the PCF network element feeds back the initial computing power routing strategy to the SMF network element based on the policy acquisition request. Based on the initial computing power routing strategy, the user terminal is controlled to establish a computing power session relationship with the anchor UFP network element. In other words, the user terminal has already completed the establishment of the computing power session relationship with the anchor UPF network element associated with the remote computing power node through the initial computing power routing strategy. In this case, if the node type of the target computing power node is a remote computing power node, the computing power routing strategy is not generated.

[0135] S603, when the generated processing result is to generate a target computing power routing strategy, the target computing power routing strategy is sent to the SMF network element, so that the SMF network element provides computing power services to the user terminal through the target computing power node based on the target computing power routing strategy.

[0136] Optionally, in this embodiment, when the generated processing result is to generate a target computing power routing policy, a target computing power routing policy is generated according to the UPF network element associated with the target computing power node. And the target computing power routing policy is sent to the SMF network element, so that the SMF network element provides computing power services to the user terminal through the target computing power node based on the target computing power routing policy. An optional implementation method for generating the target computing power routing policy in this embodiment is to generate the target computing power routing policy based on the network element identifier of the UPF network element associated with the target computing power node and the terminal identifier of the user terminal.

[0137] In this embodiment, an optional implementation method for providing computing power services to user terminals through target computing power nodes based on the target computing power routing strategy is to control the establishment of a computing power session relationship between the user terminal and the target computing power node based on the target computing power routing strategy when the target computing power routing strategy generated by the CPCF network element is obtained, and when the computing power session is successfully established, provide computing power services to the user terminal through the target computing power node.

[0138] In this embodiment, another optional implementation method for providing computing power services to user terminals through target computing power nodes based on the target computing power routing strategy is to control the UPF network element associated with the target computing power node of the user terminal to establish a computing power session relationship based on the target computing power routing strategy. If the computing power session relationship is successfully established, the computing power service is provided to the user terminal through the target computing power node.

[0139] Optionally, in this embodiment, the target computing power routing strategy can be sent to the SMF network element through the PCF network element.

[0140] Optionally, the target computing power routing policy in this embodiment can be applied to the embodiment of "If the node type of the target computing power node is a remote computing power node, the computing power routing policy is not generated" in the above S602, that is, the target computing power routing policy is used to instruct the SMF network element to control the computing power session relationship of the user terminal to be redirected to the relay UPF network element associated with the target computing power node, and when the computing power session relationship is successfully redirected, the computing power service is provided to the user terminal through the target computing power node.

[0141] In this embodiment, the computing power session information sent by the SMF network element is received, and the target computing power node is selected from the candidate computing power nodes based on the computing power session information and the computing power status information of the candidate computing power nodes. Based on the node type of the target computing power node, the computing power routing strategy is generated. In the case where the generation processing result is to generate a target computing power routing strategy, the target computing power routing strategy is sent to the SMF network element, and the SMF network element provides computing power services to the user terminal through the target computing power node based on the target computing power routing strategy. In this embodiment, based on the coordination and cooperation of the SMF network element and the CPCF network element, the optimal computing power node that provides computing power services to the user terminal, that is, the target computing power node, can be accurately selected based on the computing power session information of the user terminal. Based on this application, not only the flexibility of computing power node selection is increased, but also based on the coordination and cooperation between network element devices, a target computing power node that better matches the computing power session information can be selected, which effectively improves the efficiency and quality of computing power services.

[0142] In one embodiment, in order to improve the timeliness of providing computing power services to user terminals, such as Figure 7 As shown, in S601, an optional implementation method of selecting a target computing node from candidate computing nodes based on computing session information and computing state information of the candidate computing nodes includes:

[0143] S701, based on the computing power requirement type and the computing power resource type of each edge computing power node, select a first computing power node from each edge computing power node.

[0144] The computing power requirement type refers to the type of computing power resources required. The first computing power node refers to an edge computing power node that meets the computing power requirement type.

[0145] Optionally, in this embodiment, the computing power demand type is matched with the computing power resource type of each edge computing power node, and the edge computing power node whose computing power resource type matches the computing power demand type is used as the first computing power node.

[0146] S702: Determine the computing power service time cost of each first computing power node according to the computing power demand and the number of available computing power units of each first computing power node.

[0147] The computing power requirement refers to the number of computing power units required. The number of available computing power units refers to the number of computing power units currently available in the first computing power node. The computing power service time cost refers to the total time cost of providing computing power services to the user terminal.

[0148] Optionally, in this embodiment, the computing power processing time of each first computing power node is determined according to the computing power demand and the number of available computing power units of each first computing power node. The computing power service time cost of each first computing power node is determined according to the computing power processing time and the service waiting time of each first computing power node. Optionally, in this embodiment, the ratio of the computing power demand to the number of available computing power units can be used as the computing power processing time. The sum of the computing power processing time and the service waiting time is used as the computing power service time cost.

[0149] S703: Determine the target computing power node according to the maximum tolerance time and the computing power service time cost of each first computing power node.

[0150] Optionally, in this embodiment, if there is a first computing node whose computing service time cost is less than the maximum tolerance time, the first computing node whose computing service time cost is less than the maximum tolerance time is used as the second computing node. The second computing node with the shortest computing service time is used as the target computing node.

[0151] In this embodiment, based on the computing power demand type and the computing power resource type of each edge computing power node, a first computing power node is selected from each edge computing power node. According to the computing power demand size and the number of available computing power units of each first computing power node, the computing power service time cost of each first computing power node is determined. According to the maximum tolerance time and the computing power service time cost of each first computing power node, the target computing power node is determined. Based on this embodiment, the computing power node with the lowest computing power service time cost can be selected as the target computing power node to improve the timeliness and efficiency of computing power services.

[0152] On the basis of the above embodiment, the target computing node can also be selected from the candidate computing nodes based on the intelligent computing power allocation model, the computing power session information and the computing power status information of the candidate computing power nodes. The training method of intelligent computing power allocation is as follows:

[0153] like Figure 8 As shown, assuming that The computing service requests of user terminals can form a scheduling queue , for user terminals , Respectively represent user terminals No. The computing power requirement type, computing power requirement size, and maximum tolerance duration of each computing power service request.

[0154] The multi-computing service requests of multiple user terminals form a task queue, hoping to use the idle computing power in the edge computing server. By designing states, rewards and actions, if a computing service request of a certain user terminal can be satisfied by the computing resources allocated by the edge computing server, the mobile computing network computing scheduling process is triggered, that is, the target computing node is the edge computing node. If it cannot be satisfied, the computing service request will remain sent to the remote computing node (that is, the target computing node is the remote computing node). The specific states, rewards and actions are designed as follows:

[0155] state It can be expressed as:

[0156] (1)

[0157] Among them, in formula (1) Represents the computing resources in the edge computing node, with dimensions of ,in Indicates the number of computing units at a certain moment, Indicates the number of available time slots for allocation.

[0158] action Used to describe how to allocate computing resources and define is the action space,

[0159] (2)

[0160] Among them, in formula (2) Indicates a computing service request of a certain user in Time is allocated A computing unit. Indicates that the edge computing node cannot meet the computing power requirements of the task within the maximum tolerance time.

[0161] Reward function: Designing a reasonable reward function to meet user needs and accelerate convergence is the key to the algorithm. In order to meet as many user computing power application needs as possible at the edge computing power node, thereby achieving the purpose of optimizing computing latency in the mobile computing power network, the reward function is designed as follows:

[0162] (3)

[0163] Among them, in formula (3) This means that when the edge computing node cannot meet the computing power requirement, the corresponding task is calculated on the remote computing node. In this case, the computing time cost will be greatly increased. represents this cost. If the calculation can be performed on the edge computing node and the plan, Represents the total cost, the total time cost includes queue waiting time and task calculation time. Less than the maximum tolerance time required for the computing power , then the reward value takes the maximum value and all costs in the reward function take negative values.

[0164] Optionally, in this embodiment, the intelligent computing power allocation model can be trained based on various reinforcement learning algorithms, such as DQN, Rainbow and other algorithms until convergence is completed.

[0165] In this embodiment, through the intelligent computing power allocation model, based on the computing power session information and the computing power status information of each candidate computing power node, the candidate computing power node selected for the execution action with the largest reward value is used as the target computing power node.

[0166] In one embodiment, if Fig. 9 As shown, another optional implementation of a computing power service method includes:

[0167] S901, the SMF network element obtains the computing power session establishment request initiated by the user terminal through the AMF network element, which carries the computing power session information.

[0168] S902, the SMF network element sends a policy acquisition request to the PCF network element.

[0174] S908, the CPCF network element determines the computing service time cost of each first computing node according to the computing processing time and service waiting time of each first computing node.

[0175] S909: In the absence of a first computing node whose computing service time cost is less than the maximum tolerance time, the CPCF network element uses the remote computing node as the target computing node.

[0176] S910, in the case where there is a first computing power node whose computing power service time cost is less than the maximum tolerance time, the CPCF network element uses the first computing power node whose computing power service time cost is less than the maximum tolerance time as the second computing power node;

[0182] In this embodiment, the SMF network element receives a computing power session establishment request initiated by a user terminal and carries computing power session information, and sends the computing power session information to the CPCF network element. The CPCF network element selects a target computing power node from the candidate computing power nodes based on the computing power session information and the computing power status information of the candidate computing power nodes, and generates a computing power routing strategy based on the node type of the target computing power node. When the target computing power routing strategy generated by the CPCF network element is obtained, computing power services are provided to the user terminal through the target computing power node based on the target computing power routing strategy. Compared with the situation where each traditional network element device does not have related functions such as providing computing power service coordination and scheduling, and cannot select the optimal computing power node for the user, in this application, based on the collaborative cooperation of the SMF network element and the CPCF network element, the optimal computing power node, that is, the target computing power node, that provides computing power services to the user terminal can be accurately selected based on the computing power session information of the user terminal. Based on this application, not only the flexibility of computing power node selection is increased, but also based on the coordination and cooperation between network element devices, a target computing power node that better matches the computing power session information can be selected, effectively improving the efficiency and quality of computing power services.
