As shown in fig. 1, the two-layer networking method based on 5G customized networking of the present embodiment may be applied to a temporary networking configuration server, and the method may include the following steps:

Step S11: and receiving the requirement information of the temporary networking task sent by the user task requester by utilizing a first resource in all resources of the long-term application network, and setting the rest resources except the first resource in all the resources of the long-term application network into a standby state.

The present embodiment also establishes a long-term application network, which refers to applications or services that exist in the network for a long time, whose data flow is generally stable and continuous, and these applications may be long-term running services, application programs, communication links, and the like.

The temporary networking configuration server in this embodiment is used to manage all resources of the long-term application network. The temporary networking configuration server can utilize a first resource in all resources of the long-term application network to construct a temporary two-layer network for the long-term application network.

And the temporary networking configuration server can receive the requirement information of the temporary networking task sent by the user task requester through the UPF.

Wherein UPF (User Plane Function) is a core component of the 5G core network, which is located between the user plane and the control layer, and its main function is to provide user panel services, so as to implement functions of air interface, routing, qoS, security, etc. The UPF application can provide safer and more reliable service for 5G mobile networks, internet of things, intelligent home and the like, so that the service quality and the operation capability of the UPF can be improved.

The identification information is that each network node initiates a PDU session establishment request, establishes an N4 session channel through an N4 interface of SMF and UPF, completes 5G basic networking to realize communication, and is transmitted to the temporary networking configuration server through the UPF.

Specifically, each network node may first send a PDU session establishment request to an SMF (Session Management function, session management function, responsible for tunnel maintenance, IP address allocation and management, UPF selection, policy enforcement, and control in QoS, charging data collection, roaming, etc.) through an AMF (ACCESS AND Mobility Management Function, access and mobility management functions, primary responsibilities include registration management, connection management, and mobility management); the SMF establishes an N4 session channel with the UPF through an N4 interface based on the PDU session establishment request, and the UPF returns a channel establishment response to the SMF; the SMF reports the identification information of each network node to the temporary networking configuration server based on the channel establishment response returned by the UPF, and the temporary networking configuration server receives the identification information of each network node reported by the first resource.

Illustratively, in an embodiment, as shown in fig. 2, fig. 2 is a schematic diagram illustrating communication between a network node and a temporary networking configuration server according to an embodiment of the present invention. Each network node (such as branch a: terminal, branch B: terminal, etc.) may first send a PDU session establishment request to the SMF through the AMF, the SMF establishes an N4 session channel with the UPF through the N4 interface based on the PDU session establishment request, and the UPF returns a channel establishment response to the SMF; the SMF reports the terminal information (such as identification information) of each network node to a temporary networking configuration server based on a channel establishment response returned by the UPF; the temporary networking configuration server gives communication authority to the corresponding network nodes (such as branch A: terminal, branch B: terminal, etc.) based on the terminal information; and the network node (such as a branch A: terminal, a branch B: terminal and the like) sends own resource basic information to the temporary networking configuration server through UPF under the condition of having communication authority, and the reporting of the respective resource basic information is completed.

And, in one embodiment, as shown in fig. 5, fig. 5 is a schematic diagram of a 5G customized web-based long-term application network according to one embodiment of the present invention. In fig. 5, the branch CPEs are hardware resources in the long-term application network, each CPE may be connected to a plurality of service systems and/or terminals, and two-layer forwarding may be performed between the branch CPEs. The long-term application network may communicate with each branch CPE via UPF in the 5G DNN domain based on the base station, and may specifically communicate based on 5GC network elements (e.g., UDM, PCF, MEC, AMF, SMF, etc.). Wherein the base station is an infrastructure in a wireless communication network for providing radio signal coverage, connecting the user terminal and the core network. The temporary networking configuration server can analyze task demand information by the task demand analysis module, generate a temporary networking configuration strategy based on the strategy generation module, and issue and execute the temporary networking configuration strategy based on the construction execution module. And, in an alternative embodiment, the temporary networking configuration server may be configured on the MEC.

Specifically, the construction of the long-term application network may be: normally building a 5G customized network, wherein the type of the packet network and the deployment position of the user name do not need to be distinguished; when the firewall works in the active-standby mode, the flow can only be sent to the device for the VRRP active use, and the problem that the fragmentation message is sent to two devices does not exist. For the interfacing of the firewall and the CE/ASBR, it is necessary to guarantee the message to the primary firewall through VRRP or routing priority. And part of machine types need to check a hash algorithm in a stacking mode, so that the continuity of the fragmented messages is ensured. And all CPEs in the long-term application network normally log on to the network to acquire an IP address, and realize normal intercommunication of N6 with the service server. For large networking, when two layers of interconnection or local interconnection is needed, the requirement is realized by the networking method. The long-term application network of the present embodiment refers to an application or service that exists in the network for a long time, and the data flow thereof is generally stable and continuous. The networking method can gather the links of the long-term application network to the temporary networking configuration server (namely, the basic information of the terminal is reported to the temporary networking configuration server), so that the server becomes a central node, and the traffic and data transmission of the long-term application network are uniformly managed.
