[0002] Cloud Private Line (Cloud VPN) is a high-speed, low-latency, stable, and secure dedicated connection between a user's on-premises data center and a virtual private cloud (VPC) on the cloud. Flexible network connectivity is the cornerstone of distributed environment integration. Cloud Private Line enables data services between the cloud VPC and the user's data center. Users can use Cloud Private Line to connect their user networks, data centers, and hosting areas to the cloud VPC dedicated line connection, enjoying a high-performance, low-latency, and secure dedicated data network.

[0003] Cloud-network convergence refers to the combination of "cloud computing" and "communication networks," introducing cloud computing into communication networks and network technologies into cloud computing—in other words, the networking of the cloud and the cloudification of the network.

[0118] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0119] In the existing technology, during the establishment of a cloud dedicated line, the core network's UPF (User Plane Function) needs to complete the encapsulation and decapsulation of the GTP-U (GRPS Tunneling Protocol) protocol, collaborate with the 5G core network, 5G dedicated line controller, and cloud network controller, and direct the data flow to the cloud data center based on traffic matching filters to establish a dedicated connection from the terminal to the 5G terminal to the VPC (Virtual Private Cloud).

[0120] In the embodiment of the present application, in order to improve the method for creating a cloud dedicated line, such as Figure 2 As shown, a vUPF (Virtual User Plane Function) is set up in the edge data center and the cloud data center, respectively. The vUPF set up in the edge data center is used to perform routing and forwarding functions for user plane data packets between 5G terminals and the 5G core network. In the embodiment of this application, the vUPF set up in the edge data center is denoted as the "first UPF." The vUPF set up in the cloud data center is used to perform routing and forwarding functions for user plane data packets between the cloud data center and the 5G core network. In the embodiment of this application, the vUPF set up in the cloud data center is denoted as the "second UPF."

[0121] In the embodiment of the present application, the UPF (User Plane Function) based on NFV (Network Function Virtualization), that is, the vUPF is a virtualized functional module.

[0122] In the embodiment of the present application, the vUPF set up in the edge data center collaborates with the vUPF set up in the cloud data center, and the cloud network controller directly configures the deployment and monitors the maintenance. The 5G core network and the cloud network controller collaborate to establish a cloud VPN (i.e., virtual private network) dedicated line for cloud-edge collaboration, thereby realizing the deep integration of the 5G core network and cloud services and improving deployment efficiency.

[0123] The embodiment of the present application discloses a method for establishing a cloud dedicated line, which is applied to edge data centers, such as Figure 1 As shown, the method includes: steps 110 to 140.

[0124] The following combination Figure 2 The specific implementation of a method for establishing a cloud dedicated line disclosed in the embodiment is illustrated by way of example.

[0125] Step 110: In response to the triggering of the 5G terminal, generate a cloud dedicated line establishment request.

[0126] In some embodiments of the present application, a 5G terminal can trigger a built-in application to send a request to the edge data center of the cell where it is located to request the establishment of a cloud dedicated line. The request will carry the identification of the 5G terminal and the required parameter information of the cloud dedicated line to be established. The required parameter information may include, for example: the account number and password of the 5G terminal, the size of the requested cloud dedicated line (i.e., VPN, virtual private network), network bandwidth, resource allocation duration, resource usage time, service level, cloud data center identification, and other information.

[0127] The edge data center generates a cloud dedicated line establishment request based on the demand parameter information of the cloud dedicated line to be established carried in the request sent by the 5G terminal and the identifier of the first UPF set locally.

[0128] Optionally, the cloud dedicated line establishment request carries request parameters of the cloud dedicated line to be established. Optionally, the request parameters include: the identifier of the first UPF, the cloud data center identifier, and required parameter information of the cloud dedicated line to be established.

[0129] The identifier of the first UPF may be an IP address corresponding to the first UPF.

[0130] The cloud data center identifier is the network identifier of the cloud data center at the other end of the cloud dedicated line requested by the 5G terminal to be established, for example, an IP address, a URL (uniform resource locator), etc.

[0131] Step 120, through the locally set first UPF, sends the cloud dedicated line establishment request to the cloud network controller, so that the cloud network controller responds to the cloud dedicated line establishment request, establishes the cloud dedicated line according to the cloud dedicated line establishment request, and obtains the cloud dedicated line configuration information of the cloud dedicated line.

[0132] The edge data center receives the request sent by the 5G terminal through the first UPF, then generates a cloud dedicated line establishment request based on the request of the 5G terminal, and sends the cloud dedicated line establishment request to the cloud network controller through the first UPF.

[0133] In an embodiment of the present application, after receiving the cloud dedicated line establishment request, the cloud network controller responds to the cloud dedicated line establishment request, establishes the cloud dedicated line according to the cloud dedicated line establishment request, and obtains the cloud dedicated line configuration information of the cloud dedicated line.

[0134] Optionally, the cloud network controller responds to the cloud dedicated line establishment request, establishes a cloud dedicated line according to the cloud dedicated line establishment request, and obtains the cloud dedicated line configuration information of the cloud dedicated line, including: the cloud network controller responds to the cloud dedicated line establishment request, obtains the request parameters carried in the cloud dedicated line establishment request, wherein the request parameters include: the identifier of the first UPF, the cloud data center identifier and the requirement parameter information of the cloud dedicated line requested to be established; the cloud network controller pre-creates the cloud dedicated line according to the request parameters and obtains the cloud dedicated line configuration information of the cloud dedicated line.

[0135] After receiving the cloud dedicated line establishment request from the first UPF, the cloud network controller first parses the request to obtain the request parameters carried in the request. Then, based on the required cloud dedicated line parameters included in the request parameters, it pre-creates the dedicated line using a pre-created cloud dedicated line method to obtain cloud dedicated line configuration information. The cloud dedicated line configuration information is then sent to the first UPF.

[0136] In some embodiments of the present application, the cloud network controller pre-creates a cloud dedicated line according to the request parameters and obtains cloud dedicated line configuration information of the cloud dedicated line, including: sub-steps S11 to S15.

[0137] In sub-step S11, the cloud network controller obtains available resource information of the edge data center according to the identifier of the first UPF.

[0138] In embodiments of the present application, the cloud network controller manages all UPFs and can obtain available resource information for all UPFs connected to the cloud control. For example, available resource information for the edge data center where the first UPF is located can be obtained as the available resource information for the first UPF. In some embodiments of the present application, the available resource information includes, but is not limited to, one or more of the following: CPU, memory, network bandwidth, and storage space resources.

[0139] In sub-step S12, the cloud network controller obtains the available resource information of the cloud data center and the identifier of the second UPF local to the cloud data center.

[0140] The cloud network controller obtains the identifier of a second UPF set up in the cloud data center based on the cloud data center identifier carried in the request parameters of the cloud dedicated line establishment request, and obtains available resource information of the cloud data center as the available resource information of the second UPF. In some embodiments of the present application, the available resource information includes, but is not limited to, one or more of the following: CPU, memory, network bandwidth, and storage space resources.

[0141] In sub-step S13, the cloud network controller obtains the dedicated line available resources allocated to the first UPF by the 5G core network based on the available resource information of the edge data center and the available resource information of the cloud data center.

[0142] In the embodiment of the present application, the available resource information of the edge data center and the cloud data center can be calculated based on the product of the resource parameter and the resource capacity, as the dedicated line available resources allocated by the 5G core network to the first UPF. The model for calculating the available resource information of the edge data center and the cloud data center can be expressed as:

[0143] R(t)=[τ e *E(C e ,M e ,N e ,S e ),τ c *E(C c ,M c ,N c ,S c )];

[0144] Among them, τ e represents the resource parameter adjustment coefficient of the edge data center, τ c Represents the resource parameter adjustment coefficient of the cloud data center, C e ,M e ,N e ,S e They represent the available CPU, memory, network bandwidth, and storage space resources of the edge data center, respectively. c ,M c ,N c ,S c They represent the available CPU, memory, network bandwidth, and storage space resources of the cloud data center respectively, and R(t) represents the available dedicated line resources allocated to the first UPF by the 5G core network at time t.

[0145] In sub-step S14, the cloud network controller obtains resource demand information of the cloud dedicated line based on the demand parameter information.

[0146] In an embodiment of the present application, the demand parameter information also includes the service level matching the cloud dedicated line requested to be established, and the cloud network controller calculates the resources required for the cloud dedicated line based on the service level and the network bandwidth of the cloud dedicated line requested to be established.

[0147] For example, in some embodiments of the present application, the cloud network controller obtains resource requirement information for establishing the cloud dedicated line matching according to the following model:

[0148] R q,u (t) = [N u ,Qosu ];

[0149] Among them, N u Indicates the network bandwidth request value of user u (i.e. the network bandwidth of the cloud dedicated line requested by the 5G terminal), Qos u represents the service level of user u (i.e., the service level carried in the demand parameter information), R q,u (t) represents the resource demand of user u at time t (i.e., the resource demand of the cloud dedicated line requested to be established by the 5G terminal at time t).

[0150] Optionally, the cloud network controller can define a corresponding vUPF configuration for each service level. For example, level 1 corresponds to 1 vCPU (virtual central processing unit), 2GB of memory, and 10GB of storage space; level 2 corresponds to 2 vCPUs, 4GB of memory, and 20GB of storage space. This allows the cloud network controller to convert resources based on service level and obtain the CPU, memory, network bandwidth, and storage space resources required by the 5G terminal requesting the cloud dedicated line as resource requirement information.

[0151] Sub-step S15, in response to the available resources of the dedicated line meeting the resource requirements indicated by the resource requirement information, the cloud network controller pre-creates a cloud dedicated line between the 5G terminal and the cloud data center based on the first UPF and the second UPF, and obtains the cloud dedicated line configuration information of the cloud dedicated line.

[0152] Optionally, when the CPU, memory, network bandwidth, and storage space resources in the available resources of the dedicated line are greater than the corresponding resource requirement values ​​in the resource requirement information, it can be considered that the available resources of the first UPF meet the resource requirements of the cloud dedicated line requested to be created. In this case, the cloud network controller can establish a VPN based on the request parameters and use the obtained VPN identifier as the established cloud dedicated line identifier.

[0153] In some embodiments of the present application, if the cloud network controller determines that the available resources of the first UPF do not meet the resource requirements of the cloud dedicated line requested to be created, new cloud resources are added to the first UPF or the second UPF.

[0154] In some embodiments of the present application, after the cloud network controller completes the pre-creation of the cloud dedicated line, the cloud dedicated line configuration information of the cloud dedicated line is simultaneously sent to the first UPF and the second UPF.

[0155] Step 130: Receive the cloud dedicated line configuration information sent by the cloud network controller.

[0156] The edge data center receives the cloud dedicated line configuration information sent by the cloud network controller through the first UPF.

[0157] Step 140: Report the cloud dedicated line configuration information to the 5G core network, so that the 5G core network sends the base station configuration information corresponding to the cloud dedicated line to the base station corresponding to the edge data center according to the cloud dedicated line configuration information, and sends a test notification of the cloud dedicated line to the 5G terminal after the base station configuration information takes effect.

[0158] Afterwards, the edge data center reports the received cloud dedicated line configuration information to the 5G core network through the first UPF, and the 5G core network performs the hardware configuration related to the requested cloud dedicated line to complete the cloud dedicated line establishment process.

[0159] In some embodiments of the present application, the 5G core network sends the base station configuration information corresponding to the cloud dedicated line to the base station corresponding to the edge data center based on the cloud dedicated line configuration information, including: sub-step S21 and sub-step S22.

[0160] In sub-step S21, the 5G core network performs resource evaluation on the base station and service network of the edge data center based on the cloud dedicated line configuration information to obtain a resource evaluation result.

[0161] First, the 5G core network evaluates the resources of the cell base station where the edge data center resides, and whether the resources of the service network meet the resource requirements of the requested cloud dedicated line, based on the cloud dedicated line configuration information. Optionally, the evaluation indicators for cell base station resources include, but are not limited to, one or more of the following resource indicators: radio frequency indicators, output power, number of channels, etc. Optionally, the evaluation indicators for the service network include, but are not limited to, one or more of the following resource indicators: number of connected users, call volume, network bandwidth, etc.

[0162] After receiving the cloud dedicated line configuration information reported by the first UPF, the 5G core network obtains the relevant resource indicator values ​​and resource usage of the base station and service network of the edge data center corresponding to the first UPF. It then compares the resources available for the pre-established cloud dedicated line from the base station and service network with the resources required for the cloud dedicated line indicated in the cloud dedicated line configuration information, assesses whether the base station and service network can meet the resource requirements of the cloud dedicated line, and obtains a resource evaluation result.

[0163] For specific solutions for evaluating whether base station and service network resources meet the resource requirements for establishing a cloud dedicated line, please refer to the prior art and will not be repeated in the embodiments of this application.

[0164] In sub-step S22, when the resource evaluation result indicates that the resources of the base station and the service network meet the cloud dedicated line configuration information, the 5G core network sends the base station configuration information corresponding to the cloud dedicated line to the base station.

[0165] In some embodiments of the present application, the base station configuration information includes: cloud dedicated line parameters (i.e., VPN parameters), which are but not limited to one or more of the following: cloud dedicated line identifier (such as VPN ID), channel identifier (such as channel ID), port, mapping IP, connection account, key, network bandwidth, etc.

[0166] When the resource evaluation result indicates that the resources of the base station and the service network meet the cloud dedicated line configuration information, the 5G core network sends the base station configuration information corresponding to the cloud dedicated line to the base station, so that the base station makes hardware preparations for the cloud dedicated line.

[0167] After the base station configuration information takes effect at the base station, the 5G core network sends a cloud dedicated line test notification to the 5G terminal through the first UPF. Optionally, the 5G core network sends a cloud dedicated line test notification to the cloud network controller through the second UPF.

[0168] After receiving the cloud dedicated line test notification, the 5G terminal establishes a network connection (such as the connection mapping IP and port) according to the cloud dedicated line parameters configured in the previous steps to test whether it is successfully connected to the VPN corresponding to the cloud dedicated line.

[0169] When the resource evaluation result indicates that the resources of the base station and the service network do not meet the cloud dedicated line configuration information, the 5G core network sends a cloud dedicated line establishment failure notification to the 5G terminal through the first UPF.

[0170] Optionally, the 5G core network sends a cloud dedicated line creation failure notification to the cloud network controller through the second UPF. After receiving the cloud dedicated line establishment failure notification sent by the 5G core network, the second UPF reports the notification to the cloud network controller, and the cloud network controller deletes the pre-created cloud dedicated line and releases related resources.

[0171] The cloud dedicated line establishment method disclosed in the embodiment of the present application is applied to the edge database. The method establishes vUPF in the edge cloud and the cloud data center respectively, generates a cloud dedicated line establishment request in response to the trigger of the 5G terminal; sends the cloud dedicated line establishment request to the cloud network controller through the locally set first UPF, so that the cloud network controller responds to the cloud dedicated line establishment request, establishes the cloud dedicated line according to the cloud dedicated line establishment request, and obtains the cloud dedicated line configuration information of the cloud dedicated line; receives the cloud dedicated line configuration information sent by the cloud network controller; reports the cloud dedicated line configuration information to the 5G core network, so that the 5G The core network sends the base station configuration information corresponding to the cloud dedicated line to the base station corresponding to the edge data center based on the cloud dedicated line configuration information, and sends a test notification of the cloud dedicated line to the 5G terminal after the base station configuration information takes effect. The 5G terminal can connect to the VPN corresponding to the cloud dedicated line, combining cloud-network integration and cloud-edge collaborative architecture. Without the participation of the bearer network, it directly establishes a dedicated connection from the edge data center to the cloud data center. The 5G core network and cloud network controller collaborate to achieve rapid deployment and efficient management of cloud dedicated lines on 5G networks, reduce the deployment cost of cloud dedicated lines on 5G networks, and improve the deep integration of 5G cloud network services.

[0172] At the same time, the first UPF of the edge data center reports the cloud dedicated line configuration information issued by the cloud network controller to the 5G core network, which simplifies the cloud dedicated line establishment process and can further improve the efficiency of cloud dedicated line establishment.

[0173] Furthermore, by having the cloud network controller uniformly predict and configure the resource requirements of the first UPF, resource allocation and utilization efficiency can be improved.

[0174] The embodiment of the present application also discloses a method for establishing a cloud dedicated line, which is applied to Figure 2 The cloud network controller in the communication system shown in Figure 3 As shown, the method includes: steps 310 to 330.

[0175] Step 310: In response to the cloud dedicated line establishment request sent by the first UPF locally in the edge data center, obtain the request parameters carried in the cloud dedicated line establishment request.

[0176] The specific implementation method of the edge data center generating a cloud dedicated line establishment request is described above and will not be repeated here.

[0177] The edge data center sends a cloud dedicated line establishment request to the cloud network controller through the local first UPF.

[0178] After the cloud network controller receives the cloud dedicated line establishment request sent by the first UPF, it obtains the request parameters carried in the cloud dedicated line establishment request by processing the cloud dedicated line establishment request.

[0179] Step 320: Pre-create a cloud dedicated line according to the request parameters and obtain cloud dedicated line configuration information of the cloud dedicated line.

[0180] Afterwards, the cloud network controller pre-creates a cloud dedicated line according to the request parameters and obtains cloud dedicated line configuration information of the pre-created cloud dedicated line.

[0181] In some embodiments of the present application, the request parameters include: the identifier of the first UPF, the cloud data center identifier and the required parameter information of the cloud dedicated line requested to be established, and the pre-creation of the cloud dedicated line based on the request parameters and the acquisition of the cloud dedicated line configuration information of the cloud dedicated line include: sub-steps 3201 to 3205.

[0182] Sub-step 3201: Obtain available resource information of the edge data center according to the identifier of the first UPF.

[0186] Sub-step 3203: Obtain the dedicated line available resources allocated to the first UPF by the 5G core network based on the available resource information of the edge data center and the available resource information of the cloud data center.

[0187] The cloud network controller obtains the specific implementation method of the dedicated line available resources allocated to the first UPF by the 5G core network based on the available resource information of the edge data center and the available resource information of the cloud data center. Please refer to the description in the previous text and will not repeat it here.

[0188] Sub-step 3204: Obtain resource demand information of the cloud dedicated line based on the demand parameter information.

[0190] Sub-step 3205, in response to the available resources of the dedicated line meeting the resource requirements indicated by the resource requirement information, based on the first UPF and the second UPF, pre-create a cloud dedicated line between the 5G terminal and the cloud data center, and obtain the cloud dedicated line configuration information of the cloud dedicated line.

[0191] If the cloud network controller determines that the available resources (such as CPU, memory, network bandwidth, and storage space resources) of the dedicated line are greater than the corresponding resource requirement values ​​in the resource requirement information, it can be considered that the available resources of the first UPF meet the resource requirements of the cloud dedicated line requested. In this case, the cloud network controller can establish a VPN based on the request parameters and use the obtained VPN identifier as the identifier of the established cloud dedicated line.

[0192] In some embodiments of the present application, based on the first UPF and the second UPF, a cloud dedicated line is pre-created between the 5G terminal and the cloud data center to obtain cloud dedicated line configuration information of the cloud dedicated line, including: establishing a communication tunnel between the first UPF and the second UPF according to the demand parameter information, and obtaining the tunnel identifier of the communication tunnel; establishing a cloud dedicated line according to the tunnel identifier, and obtaining a cloud dedicated line identifier and cloud dedicated line parameters; obtaining the cloud dedicated line configuration information of the cloud dedicated line according to the tunnel identifier, the cloud dedicated line identifier and the cloud dedicated line parameters.

Please refer to the description in the previous article and will not repeat it here.

[0194] In some embodiments of the present application, if the cloud network controller determines that the available resources of the first UPF do not meet the resource requirements of the cloud dedicated line requested to be created, new cloud resources are added to the first UPF or the second UPF.

[0195] Step 330: Send the cloud dedicated line configuration information to the first UPF, so that the first UPF reports the cloud dedicated line configuration information to the 5G core network, triggering the 5G core network to send the base station configuration information corresponding to the cloud dedicated line to the base station corresponding to the edge data center according to the cloud dedicated line configuration information, and after the base station configuration information takes effect, send the cloud dedicated line test notification to the 5G terminal.

[0196] In some embodiments of the present application, after the cloud network controller completes the pre-creation of the cloud dedicated line, the cloud dedicated line configuration information of the pre-created cloud dedicated line is simultaneously sent to the first UPF and the second UPF.

[0197] After the first UPF receives the cloud dedicated line configuration information issued by the cloud network controller, it reports the cloud dedicated line configuration information to the 5G core network.

[0198] After the 5G core network receives the cloud dedicated line configuration information reported by the first UPF, the 5G core network performs a resource evaluation on the base station and service network where the edge data center is located according to the cloud dedicated line configuration information to obtain a resource evaluation result; and when the resource evaluation result indicates that the resources of the base station and the service network meet the cloud dedicated line configuration information, the base station configuration information corresponding to the cloud dedicated line is sent to the base station.

[0199] The 5G core network performs resource evaluation on the base station and service network of the edge data center based on the cloud dedicated line configuration information, and obtains the specific implementation method of the resource evaluation result. Please refer to the previous description and will not repeat it here.

[0200] In some embodiments of the present application, when the resource evaluation result indicates that the resources of the base station and the service network meet the cloud dedicated line configuration information, the 5G core network sends the base station configuration information corresponding to the cloud dedicated line to the base station, and after the base station configuration information takes effect, sends a test notification of the cloud dedicated line to the 5G terminal through the first UPF.

[0201] In some embodiments of the present application, when the resource evaluation result indicates that the resources of the base station and the service network do not meet the cloud dedicated line configuration information, the 5G core network sends a cloud dedicated line establishment failure notification to the 5G terminal through the first UPF.

[0202] At the same time, the 5G core network sends a cloud dedicated line establishment failure notification to the cloud network controller through the second UPF.

[0206] After the cloud network controller receives the cloud dedicated line establishment failure notification reported by the second UPF, it deletes the pre-created cloud dedicated line and releases related resources.

[0207] The embodiment of the present application also discloses a cloud dedicated line establishment method, which is applied to a cloud network controller. The method establishes vUPFs in an edge cloud and a cloud data center respectively, and then responds to a cloud dedicated line establishment request sent by a first UPF local to the edge data center, obtains request parameters carried in the cloud dedicated line establishment request; pre-creates a cloud dedicated line according to the request parameters, obtains cloud dedicated line configuration information of the cloud dedicated line; sends the cloud dedicated line configuration information to the first UPF, so that the first UPF reports the cloud dedicated line configuration information to the 5G core network, triggering the 5G core network to establish a cloud dedicated line according to the request parameters; The line configuration information is sent to the base station corresponding to the edge data center, and after the base station configuration information takes effect, the test notification of the cloud dedicated line is sent to the 5G terminal. The 5G terminal can connect to the VPN corresponding to the cloud dedicated line. It combines cloud-network integration and cloud-edge collaborative architecture, and directly establishes a dedicated connection from the edge data center to the cloud data center without the participation of the bearer network. The 5G core network and cloud network controller work together to achieve rapid deployment and efficient management of 5G online cloud dedicated lines, reduce the deployment cost of 5G online cloud dedicated lines, and improve the deep integration of 5G cloud network services.

[0208] At the same time, the first UPF of the edge data center reports the cloud dedicated line configuration information issued by the cloud network controller to the 5G core network, which simplifies the cloud dedicated line establishment process and can further improve the efficiency of cloud dedicated line establishment.

[0209] Furthermore, by having the cloud network controller uniformly predict and configure the resource requirements of the first UPF, resource allocation and utilization efficiency can be improved.

[0210] The embodiment of the present application also discloses a method for establishing a cloud dedicated line, which is applied to Figure 2 The 5G core network in the communication system shown in Figure 5 As shown, the method includes: steps 510 to 530.

[0211] Step 510, in response to the cloud dedicated line configuration information reported by the first UPF of the edge data center, perform resource evaluation on the base station and service network of the edge data center according to the cloud dedicated line configuration information to obtain a resource evaluation result.

[0212] Among them, the cloud dedicated line configuration information is obtained through the following method: the edge data center generates a cloud dedicated line establishment request in response to the trigger of the 5G terminal; the edge data center sends the cloud dedicated line establishment request to the cloud network controller through the first UPF set up locally, so that the cloud network controller responds to the cloud dedicated line establishment request, establishes a cloud dedicated line between the edge data center and the cloud data center according to the cloud dedicated line establishment request, and obtains the cloud dedicated line configuration information of the cloud dedicated line; the edge data center receives the cloud dedicated line configuration information sent by the cloud network controller through the second UPF set up in the cloud data center; the edge data center reports the cloud dedicated line configuration information to the 5G core network through the first UPF.

[0213] The method for generating Cloud Direct Connection configuration information is described above and will not be repeated here.

[0214] The 5G core network performs resource evaluation on the base station and service network of the edge data center based on the cloud dedicated line configuration information, and obtains the specific implementation method of the resource evaluation result. Please refer to the previous description and will not repeat it here.

[0215] Step 520: In response to the resource evaluation result indicating that the resources of the base station and the service network meet the cloud dedicated line configuration information, the base station configuration information corresponding to the cloud dedicated line is sent to the base station.

[0216] In some embodiments of the present application, when the resource evaluation result indicates that the resources of the base station and the service network meet the cloud dedicated line configuration information, the 5G core network sends the base station configuration information corresponding to the cloud dedicated line to the base station.

[0217] Step 530: In response to the base station configuration information taking effect, a test notification of the cloud dedicated line is sent to the 5G terminal that requests to establish the cloud dedicated line.

[0218] Next, after the base station configuration information takes effect, the 5G core network sends a test notification of the cloud dedicated line to the 5G terminal requesting to establish the cloud dedicated line through the first UPF.

[0219] In some embodiments of the present application, when the resource evaluation result indicates that the resources of the base station and the service network do not meet the cloud dedicated line configuration information, the 5G core network sends a cloud dedicated line establishment failure notification to the 5G terminal requesting to establish the cloud dedicated line through the first UPF.

[0220] Correspondingly, such as Figure 6As shown, the resource evaluation of the base station and business network where the edge data center is located is performed according to the cloud dedicated line configuration information, and after obtaining the resource evaluation result, it also includes: step 540.

[0221] Step 540: When the resource evaluation result indicates that the resources of the base station and the service network do not meet the cloud dedicated line configuration information, a cloud dedicated line establishment failure notification is sent to the cloud network controller through the second UPF.

[0222] The cloud dedicated line establishment failure notification is used to trigger the cloud network controller to release the pre-created cloud dedicated line.

[0223] If the 5G core network evaluates that the resources of the base station and the service network do not meet the cloud dedicated line configuration information, the second UPF sends a cloud dedicated line establishment failure notification to the cloud network controller through the second UPF. After receiving the cloud dedicated line establishment failure notification sent by the 5G core network, the second UPF reports the notification to the cloud network controller.

[0224] The cloud network controller releases the pre-created cloud dedicated line in response to the cloud dedicated line establishment failure notification forwarded by the second UPF, for example, by deleting the pre-created cloud dedicated line and releasing related resources.

[0225] The embodiment of the present application also discloses a cloud dedicated line establishment method, which is applied to a 5G core network. The method establishes vUPFs in an edge cloud and a cloud data center respectively, and then responds to a cloud dedicated line establishment request sent by a first UPF in the edge data center, obtains request parameters carried in the cloud dedicated line establishment request; pre-creates a cloud dedicated line according to the request parameters, obtains cloud dedicated line configuration information of the cloud dedicated line; sends the cloud dedicated line configuration information to the first UPF, so that the first UPF reports the cloud dedicated line configuration information to the 5G core network, and the 5G core network reports the cloud dedicated line configuration information according to the cloud dedicated line. The line configuration information is sent to the base station corresponding to the edge data center, and after the base station configuration information takes effect, the test notification of the cloud dedicated line is sent to the 5G terminal. The 5G terminal can connect to the VPN corresponding to the cloud dedicated line. It combines cloud-network integration and cloud-edge collaborative architecture, and directly establishes a dedicated connection from the edge data center to the cloud data center without the participation of the bearer network. The 5G core network and cloud network controller work together to achieve rapid deployment and efficient management of 5G online cloud dedicated lines, reduce the deployment cost of 5G online cloud dedicated lines, and improve the deep integration of 5G cloud network services.

[0226] At the same time, the first UPF of the edge data center reports the cloud dedicated line configuration information issued by the cloud network controller to the 5G core network, which simplifies the cloud dedicated line establishment process and can further improve the efficiency of cloud dedicated line establishment.

[0227] Furthermore, by having the cloud network controller uniformly predict and configure the resource requirements of the first UPF, resource allocation and utilization efficiency can be improved.

[0228] In order to make the cloud dedicated line establishment method disclosed in the embodiment of this application clearer, the following Figure 7 The interactive process shown further illustrates the process of establishing the cloud dedicated line.

[0229] Step 701: The edge data center generates a cloud dedicated line establishment request in response to the triggering of the 5G terminal.

[0230] In step 702, the edge data center sends the cloud dedicated line establishment request to the cloud network controller through the locally set first UPF.

[0231] In step 703, the cloud network controller responds to the cloud dedicated line establishment request sent by the first UPF locally in the edge data center and obtains the request parameters carried in the cloud dedicated line establishment request.

[0232] In step 704, the cloud network controller pre-creates a cloud dedicated line according to the request parameters and obtains cloud dedicated line configuration information of the cloud dedicated line.

[0233] Step 705: The cloud network controller sends the cloud dedicated line configuration information to the first UPF set up in the edge data center.

[0234] Step 706: The first UPF receives the cloud dedicated line configuration information sent by the cloud network controller and reports the cloud dedicated line configuration information to the 5G core network.

[0235] In step 707, the 5G core network performs resource evaluation on the base station and service network of the edge data center based on the cloud dedicated line configuration information to obtain a resource evaluation result.

[0236] In step 708, when the resource evaluation result indicates that the resources of the base station and the service network meet the cloud dedicated line configuration information, the 5G core network sends the base station configuration information corresponding to the cloud dedicated line to the base station.

[0237] Step 709: In response to the base station configuration information taking effect, the 5G core network sends a test notification of the cloud dedicated line to the 5G terminal requesting to establish the cloud dedicated line.

[0238] In step 710, when the resource evaluation result indicates that the resources of the base station and the service network do not meet the cloud dedicated line configuration information, the 5G core network sends a cloud dedicated line establishment failure notification to the cloud network controller through the second UPF.

[0239] Step 711: The second UPF reports a failure notification of establishing a cloud dedicated line to the cloud network controller.

[0240] Step 712: The cloud network controller releases the pre-created cloud dedicated line in response to the cloud dedicated line establishment failure notification forwarded by the second UPF.

[0241] It can be seen from the above cloud dedicated line establishment process that the embodiment of the present application also discloses a cloud dedicated line establishment method. By combining cloud-network integration and cloud-edge collaborative architecture, vUPF is established in the edge cloud and cloud data center respectively to forward data. During the cloud dedicated line establishment process, no bearer network participation is required, and a dedicated connection from the edge data center to the cloud data center is directly established. The 5G core network and the cloud network controller collaborate to achieve rapid deployment and efficient management of cloud dedicated lines on the 5G network, reduce the deployment cost of 5G dedicated lines, improve the establishment efficiency of 5G cloud dedicated lines, and enhance the deep integration of 5G cloud network services.

[0242] Correspondingly, the embodiment of the present application also discloses a cloud dedicated line establishment device, which is applied to edge data centers, such as Figure 8 As shown, the device includes:

[0243] A cloud dedicated line establishment request generation module 810 is configured to generate a cloud dedicated line establishment request in response to a trigger of a 5G terminal;
