It should be noted that, the target line refers to a service broadband, where the service broadband may be an internet private line or a cloud center private line.

It should be noted that, when the private line user is a connection between two nodes, the connection may be performed at a UPF, where the UPF is a user plane unit, and is used for routing and forwarding a 5G network user plane packet.

In a specific implementation, the detection end is an optical cable fiber fault detection switching device, and specifically, the optical cable fiber fault detection switching device may include an optical splitter, an optical power detector, and the like; when the optical cable fiber fault detection switching device detects that an optical cable fiber of a special line user, namely a target line, breaks down (namely, an optical power meter detects through an optical splitter) or an optical transmission device breaks down (namely, fault alarm information of the optical transmission device is received), the special line user, namely, the target line, is controlled to be switched to a port of 5G-CPE, namely, CPE equipment from an originally used bandwidth port, namely, a service broadband user end port, by an optical transmission port, the 5G-CPE, namely, CPE equipment, provides an actual occupied bandwidth value of the optical transmission port before the fault for a server by utilizing a slicing channel, namely, a first channel, which is specially used for signal transmission, the 5G-CPE, namely, CPE equipment simultaneously initiates an attachment request message to a base station, and the base station selects a target AMF, namely, a target access and movement management unit in a plurality of AMFs, namely, according to the requested weight; after receiving the attachment request message, the target AMF, namely the target access and mobile management unit, acquires the bandwidth allocated by the private line user provided by the server, namely the allocated bandwidth, through the UDM, namely the unified data management unit according to SUCI, namely the SUPI, namely the user permanent identifier in the user hidden identifier, and sends the message passing through the registration request, namely the registration passing information, to the 5G-CPE, namely the CPE equipment, and the target AMF, namely the user plane unit, namely the allocated bandwidth allocated by the private line user provided by the user plane unit allocation server is put into use; when the optical cable fiber fault detection switching device detects that the optical cable fiber fault of the special line user, namely the target line (namely the optical power meter is detected through the optical splitter) or the optical transmission equipment fault (namely the fault alarm information of the optical transmission equipment is received) is recovered, the special line user, namely the target line, is controlled to be returned to the optical transmission port from the originally used broadband port, namely the service broadband user end port of the CPE equipment, and simultaneously a release instruction is sent to the UPF, namely the user plane unit, and the UPF, namely the user plane unit, is controlled to release the bandwidth occupied by the 5G network slice through the release instruction.

Referring to fig. 2, a flowchart illustrating steps of a method for protecting and allocating bandwidth in real time for a service broadband 5GCPE according to an embodiment of the present application is shown;

S210, when the CPE equipment receives fault information sent by the detection end, the CPE equipment establishes a slice data channel according to the fault information, wherein the slice data channel comprises a first channel for signal transmission and a second channel for service bandwidth transmission from the CPE equipment to a user plane unit through a base station;

S220, the CPE equipment sends the actual occupied bandwidth value of the service broadband user terminal port before the fault to the server through the first channel and generates an attachment request message; the server is used for receiving the actual occupied bandwidth value and determining an allocated bandwidth value corresponding to the target line through the actual occupied bandwidth value;

As an example, the 5G-CPE automatically initiates a procedure of establishing and withdrawing a slice service channel, that is, URSP (UE Route Selection Policy, UE routing policy) data is parsed and a slice data channel is established, and two 5G slice channels are simultaneously established, where a first channel is used for signal transmission and a second channel is used for service bandwidth transmission from the CPE device to the user plane unit through the base station.

In a specific implementation, when the dedicated line user, i.e. the optical cable fiber of the target line or the optical transmission device has no fault, the 5G-CPE only reserves the signal transmission slice, i.e. the first channel (usually less than 1 Mb/s), and does not establish the bandwidth transmission slice, i.e. the second channel.

And S320, when the server receives a bandwidth acquisition request sent by the unified data management unit of the 5G core network, the server sends the bandwidth allocation value to the 5G core network.

In one embodiment of the present invention, the step of determining the allocated bandwidth value corresponding to the target line by the actual occupied bandwidth value includes:

The server is an elastic slice server.

In a specific implementation, a 5G core network extracts the physical position, namely the position information, of a special line user, namely a target line in real time, wherein the physical position, namely the real-time spare bandwidth value of the 5G sector mobile communication corresponding to the position information; when the bandwidth is larger than or equal to the bandwidth allowance of the broadband widening band actually occupied by the special line user, namely the optical transmission port before the fault of the target line, the spare bandwidth of the mobile communication of the 5G sector is allocated and occupied by the broadband actually occupied by the special line user, namely the target line before the disconnection of the network, namely the value of the actually occupied bandwidth is the allocated bandwidth;

when the bandwidth is smaller than the bandwidth obtained by subtracting the broadband margin from the spare bandwidth of the mobile communication occupying the 5G sector, namely the bandwidth allocated is the difference between the real-time spare bandwidth value and the broadband margin, when the bandwidth is smaller than the bandwidth widened margin actually occupied by the special line user, namely the optical transmission port before the target line fault;

wherein the broadband margin is a preset redundant bandwidth.
