A first created SR tunnel is arranged between the UPE and the first SPE, a second created SR tunnel is arranged between the UPE and the second SPE, and the first SR tunnel and the second SR tunnel are bound with the L3VPN service. The step of adding a user side node UPE on the L3VPN service of the three-layer virtual private network means that newly creating a SPN device to be in butt joint with a 5G base station while newly creating the 5G base station, wherein the SPN device is the UPE, and the UPE is added into the L3VPN service to be in service intercommunication with an SPE and an NPE; the creation sub-interface is to configure information of VLAN, IP address and mask on a certain physical port of the UPE; the adding of the sub-interface local route means that route information is set on the sub-interface so as to realize node equipment intercommunication; and the dynamic host configuration protocol of the enabling sub-interface relays the DHCP Relay so as to enable the DHCP message of the 5G base station to be sent to core network equipment through the UPE. And after receiving the work order of the 5G transmission circuit opening, the super controller SC opens the automatic 5G transmission circuit according to the work order information. The automatic 5G transmission circuit opening comprises the following steps: step 1, the super controller SC determines whether UPE has been added to the L3VPN service, if not, then automatically executes creating a segment route SR tunnel in sequence, adds a user side node UPE on the three-layer virtual private network L3VPN service, binds the SR tunnel on the L3VPN service, creates a subinterface, adds a subinterface local route, and enables a dynamic host configuration protocol Relay DHCP Relay of the subinterface, if so, then automatically executes creating the subinterface, adding the subinterface local route, and enables the dynamic host configuration protocol Relay DHCP Relay of the subinterface in sequence.

And after receiving the work order of the 5G transmission circuit opening, the Super Controller (SC) opens the automatic 5G transmission circuit according to the work order information. The Super Controller (SC) first determines whether a UPE node has been added to the L3VPN traffic. If the UPE node is not added to the L3VPN service, the Super Controller (SC) needs to sequentially and automatically execute six operations of creating an SR tunnel, adding the UPE node on the L3VPN service, binding the SR tunnel on the L3VPN service, creating a subinterface, adding a subinterface local route and enabling a subinterface DHCP Relay; if UPE node is added to L3VPN service, only three operations of creating sub-interface, adding sub-interface local route and enabling sub-interface DHCP Relay are needed to be automatically executed in sequence.

Wherein, "creating an SR tunnel" refers to creating a SR tunnel from a UPE node to a pair of SPE nodes; the step of adding UPE nodes on the L3VPN service means that when a 5G base station is newly built, SPN equipment at one end is newly built to be in butt joint with the 5G base station, wherein the SPN equipment is UPE nodes which are required to be added into the L3VPN service and are in service intercommunication with SPE and NPE nodes in the L3VPN service; binding SR tunnels on L3VPN traffic "means binding together the two SR tunnels of UPE node to a pair of SPE nodes created in the first step with L3VPN traffic; the creation of a subinterface refers to configuring VLAN, IP address, mask and other information on a certain physical port of a UPE node; the method comprises the steps that a sub-interface local route is added, namely route information is set on the sub-interface, and the route can be communicated with other node equipment after the configuration is finished; the enabling sub-interface DHCP Relay can enable the DHCP message of the 5G base station to be transmitted to the core network equipment through the UPE sub-interface Relay.
The Super Controller (SC) provides six operation capabilities of creating an SR tunnel, adding UPE nodes on the L3VPN service, binding the SR tunnel on the L3VPN service, creating a subinterface, adding a subinterface local route and enabling a subinterface DHCP Relay. And after the Super Controller (SC) receives the opening work order, automatically configuring the 5G transmission circuit according to the work order information. The Super Controller (SC) judges whether UPE nodes are added to the L3VPN service or not, if not, six operations of creating an SR tunnel, adding UPE nodes on the L3VPN service, binding the SR tunnel on the L3VPN service, creating a sub-interface, adding a sub-interface local route and enabling a sub-interface DHCP Relay are required to be automatically executed in sequence; if so, only three operations of creating the sub-interface, adding the sub-interface local route and enabling the sub-interface DHCP Relay are needed to be automatically executed in sequence.
