Detailed Description

The technical solution of the present disclosure is further described in detail by the accompanying drawings and examples.

The inventor finds that by adopting an edge UPF deployment mode in the related technology, when a large number of edge UPFs are on line, especially the UPFs deployed in the own machine rooms of the users of the garden enterprises, the workload of deployment, debugging and the like can be greatly increased. Different manufacturers need to carry out respective private extension on the standard protocol and reserve the personalized parameter configuration of products, and the deployment efficiency is low.

A flow diagram of some embodiments of the UPF access method of the present disclosure is shown in fig. 1.

In step 111, the DHCP server receives a DHCP address request of the edge UPF, wherein the DHCP address request is forwarded by the DHCP relay device to the DHCP server from the edge UPF.

In some embodiments, the DHCP address request includes an identification of the edge UPF. In some embodiments, the identification of the edge UPF may include MAC address information of a DC (Domain Controller) -GW (GateWay) device of the edge UPF to ensure its uniqueness.

In some embodiments, the DHCP Relay device receives a DHCP address request sent by the edge UPF through broadcasting, and forwards the DHCP address request to the DHCP server through unicast, thereby ensuring that the DHCP address request can reach the server.

In some embodiments, the DHCP relay is located in an IP metropolitan area network router device, and the metropolitan area network device is connected to a DHCP server through a 5G-CE, so as to further improve the success rate and reliability of sending DHCP address requests and improve the efficiency of edge UPF access.

In step 112, the DHCP server assigns temporary management parameters to the edge UPF and sends them to the edge UPF.

In some embodiments, the DHCP server allocates a temporary management parameter to the edge UPF according to the identifier of the edge UPF, for example, when it is ensured that the identifier of the edge UPF is not allocated with the temporary management parameter, it is determined that the edge UPF is a newly accessed edge UPF, thereby avoiding management confusion caused by repeatedly allocating addresses. In some embodiments, the DHCP server may record the correspondence between the identity of the edge UPF and the temporary management parameters for subsequent querying and use.

In some embodiments, the temporary management parameters may include a temporary management address, a first gateway address, and a first mask.

In step 113, the DHCP server establishes an MML (Man-Machine Language) channel for the edge UPF based on the temporary management parameter.

In step 114, the DHCP server determines whether the edge UPF is successfully configured according to the temporary management parameters. If the configuration is successful, go to step 115; if the configuration is unsuccessful, the current flow is terminated.

In some embodiments, after sending the temporary management parameter, the DHCP server scans an address in the temporary management parameter at a predetermined interval to determine whether the edge UPF is configured successfully. If the address can be scanned and a terminal is on-line, the configuration is successful; otherwise, it is determined that the configuration has not been successful. In some embodiments, the DHCP server may continuously scan for several times, or scan for a predetermined number of times in a predetermined period, and when the terminal of the address is not scanned for several times, it is determined that the configuration is unsuccessful, so as to improve the accuracy and reliability of detection and improve the success rate of edge UPF access.

In step 115, the DHCP server issues UPF management parameters to the edge UPF through the MML tunnel. In some embodiments, the UPF management parameter may include a UPF management address, a second gateway address, and may further include routing information, an account password, and the like required by the operation and maintenance. And the edge UPF configures the parameters thereof according to the received UPF management parameters, thereby completing the access of the edge UPF.

Based on the mode in the embodiment, the DHCP server with the network management system function can obtain the access request of the edge UPF through the forwarding of the DHCP-Relay, and further realize the remote configuration of the edge UPF through twice address allocation, thereby realizing the automatic deployment and plug-and-play of the UPF and improving the convenience and efficiency of the edge DHCP access.

In some embodiments, as shown in fig. 1, the UPF access method of the present disclosure may further include

steps

116 and 117 performed after step 115.

In step 116, the DHCP server determines whether the edge UPF has been configured according to the UPF management parameters. If the configuration is complete, go to step 117; otherwise, the current flow terminates.

In some embodiments, after sending the UPF management parameter, the DHCP server scans an address in the UPF management parameter at a predetermined interval for a second duration to determine whether the edge UPF is configured successfully. If the address can be scanned and a terminal is on-line, the configuration is successful; otherwise, it is determined that the configuration has not been successful. In some embodiments, the DHCP server may continuously scan for several times, or scan for a predetermined number of times in a predetermined period, and when the terminal of the address is not scanned for several times, it is determined that the configuration is unsuccessful, so as to improve the accuracy and reliability of detection and improve the success rate of edge UPF access.

In step 117, the DHCP server accesses the edge UPF into the nanotube and performs at least one of an opening configuration, a basic service configuration, a maintenance management configuration, or a license activation on the edge UPF.

Based on the mode in the embodiment, after the successful access of the edge UPF is determined, the DHCP server with the network management function can directly manage and configure in time, so that the service efficiency of the edge UPF is improved.

A flow diagram of further embodiments of the UPF access method of the present disclosure is shown in fig. 2.

In step 221, the edge UPF generates a DHCP address request and sends the DHCP address request by broadcast. When the request is received by the DHCP Relay, the DHCP Relay converts the message into a unicast message, and the message is sent by targeting the DHCP server.

In some embodiments, the edge UPF generates a DHCP request through the DC-GW and interacts with the DHCP relay and the DHCP server.

In step 222, the edge UPF receives the temporary management parameters fed back by the DHCP server through the DHCP relay.

In step 223, the edge UPF configures its own parameters according to the received temporary management parameters.

In step 224, an MML tunnel with the DHCP server is established through the temporary management parameters, and UPF management parameters of the DHCP server are received through the tunnel.

In step 225, the parameters of the network are updated according to the UPF management parameter configuration, thereby completing the network access.

Based on the mode in the embodiment, the edge UPF can obtain the parameter information fed back by the server in a mode of broadcasting the DHCP access request, and then network access is realized through twice parameter configuration without manual configuration, so that the access efficiency and convenience are improved.
