As shown in fig. 1, an embodiment of the present invention provides an air interface resource control method, which is applied to a Session Management Function (SMF), and includes:
step 101: acquiring a port abnormal state report, wherein the port abnormal state report is used for indicating that a target port of back-end equipment connected with UE is in an abnormal state;
it should be noted that, before acquiring the port abnormal state report, the SMF needs to send a start instruction for detecting the port state of the backend device to the UE;
and returning the port abnormal state report to the SMF under the condition that the UE detects that the target port of the back-end equipment is in the abnormal state according to the starting instruction.
Step 102: and sending a PDU session change request to the UE according to the port abnormal state report, wherein the PDU session change request is used for indicating the UE to release a first air interface resource corresponding to the target port.
According to the embodiment of the invention, a port abnormal state report is obtained, wherein the port abnormal state report is used for indicating that a target port of back-end equipment connected with the UE is in an abnormal state; and sending a PDU session change request to the UE according to the port abnormal state report, wherein the PDU session change request is used for indicating the UE to release the first air interface resource corresponding to the target port and delete the air interface resource corresponding to the abnormal port, so that the purposes of managing and controlling the air interface resource and saving the air interface resource are achieved.
Optionally, the method further comprises:
and after acquiring the PDU session change completion information sent by the UE, sending an air interface resource deletion request, wherein the air interface resource deletion request is used for indicating network side equipment to release a second air interface resource corresponding to the target port.

sending a Packet Forwarding Control Protocol (PFCP) session update request to a User Plane Function (User Plane Function, abbreviated as UPF) according to the port abnormal state report, where the PFCP session update request is used to indicate the UPF to update a Forwarding Action Rule (Forwarding Action Rule, abbreviated as FAR);
after PFCP session update response information returned by the UPF is acquired, whether the FAR is updated successfully is judged;
and after the FAR updating is successful, sending the PDU session change request to the UE.
It should be noted that, according to the PDU Session ID and the QFI in the port abnormal state report, the FAR of the UPF is updated, so as to achieve the purpose of reasonably controlling the User Plane Packets (User Plane Packets) forwarding rule of the UPF.
It should be further noted that the PFCP session update response Information includes an Information Element (IE) identifier, where the IE identifier includes a first Cause Value (Cause Value) indicating that the UPF successfully updates the FAR, or at least one second Cause Value indicating that the UPF fails to update the FAR. And when the second Cause Value is acquired and the FAR update is determined to be failed, the SMF repeatedly sends the PFCP session update request until the FAR update is successful.
Optionally, the FAR comprises:
and setting the identifier in an application Action IE corresponding to the data packet sent to the target port as a discarded data packet.
Here, the corresponding identifier (Flag) in the Apply Action IE in the QFI FAR corresponding to the packet addressed to the target port is set to "DROP", that is, "discard the packet", so that the packet addressed to the abnormal port is not forwarded.

identifying correspondence consistency between the MAC address and the identification information in the port abnormal state report;
and after the correspondence is passed, sending the PFCP session update request to the UPF.

Wherein the identification information includes: at least one of PDU Session ID and QFI.
As shown in fig. 2, a second flowchart of the air interface resource control method according to the embodiment of the present invention is described:

step 203: the SMF identifies the corresponding consistency between the MAC address and the identification information in the port abnormal state report;
step 204: after the correspondence is passed, the SMF sends a PFCP session update request to the UPF according to the port abnormal state report, wherein the PFCP session update request is used for indicating the UPF to update the FAR;
step 205: the UPF returns PFCP session update response information to the SMF;
step 206: after the PFCP session update response message indicates that the FAR of the UPF is successfully updated, the SMF sends a PDU session change request to the UE according to the port abnormal state report, wherein the PDU session change request is used for indicating the UE to release a first air interface resource corresponding to the target port;
step 207: after the first air interface resource of the UE is deleted, a PDU session change completion request is returned to the SMF;
step 208: and the SMF sends a second air interface resource deletion request to the RAN.
As shown in fig. 3, an embodiment of the present invention further provides an air interface resource control method, which is applied to a UE, where the UE is connected to a backend device, and the method includes:
step 301: under the condition that the target port of the back-end equipment is detected to be in an abnormal state, a port abnormal state report is sent;
here, the exception status report is sent to the SMF.
It should be noted that, in the 5G LAN mode, the UE hangs down a plurality of backend devices, and performs communication connection with the UE through a wireless communication technology (WiFi) or a wired communication technology, for example, a Customer Premise Equipment (CPE), where the UE has an ethernet Switch function, so this mode is referred to as a 5G LAN Switch mode.
Step 302: acquiring a PDU session change request sent by the SMF according to the port abnormal state report;
it should be noted that, after the SMF receives the port abnormal state report, it is necessary to identify correspondence between the MAC address and the identification information in the port abnormal state;
after the correspondence is passed, the SMF sends a PFCP session update request to the UPF;
after the SMF receives PFCP session update response information sent by the UPF, judging whether the FAR is updated successfully;
and after the FAR updating is successful, sending the PDU session change request to the UE.
Step 303: and releasing the first air interface resource corresponding to the target port according to the PDU session change request.

acquiring a starting instruction which is sent by the SMF and used for detecting the port state of the back-end equipment;
and executing a Spanning Tree (STA) algorithm, and detecting the port state of the back-end equipment, wherein the port state comprises a normal state or an abnormal state.
It should be noted that, after receiving the start instruction sent by the SMF, the UE acquires, in a 5G LAN Switch mode, a port state of the backend device that establishes a communication connection by executing the STA algorithm, where the normal state is a Forwarding (Forwarding) state; the abnormal state includes one of: disabled (Disabled) state, blocked (Blocking) state, Listening (Listening) state, and Learning (Learning) state.
And when detecting that the port state of the back-end equipment is any one of the abnormal states, sending the port abnormal state report to the SMF.
Optionally, the port exception status report includes:
the MAC address of the target port and the identification information of the first air interface resource, where the identification information includes: at least one of PDU Session ID and QFI.

and sending PDU session change completion information to the SMF.
Here, after deleting the first air interface resource, the UE needs to return the PDU session change completion information to the SMF, so that after receiving the PDU session change completion information, the SMF instructs the network layer device to delete the second air interface resource corresponding to the target port, and further achieves the purpose of reasonably managing and controlling the air interface resource.
