Description
Technical Field
The invention relates to the technical field of computers, in particular to a 5G-based SMF session detection method, a terminal and a computer-readable storage medium.
Background
An N4 interface of a Control plane of the 5G mobile network is based on a UDP/IP protocol, and an application layer adopts a Packet Forwarding Control Protocol (PFCP) which is defined in 3GPP TS 29.244. The N4 interface transfers PFCP request and response messages between SMFs and UPFs, including the establishment, modification, release and reporting of PFCP sessions.
The N4 interface is between the SMF and the UPF, and is an interface between the 5G core network control plane and the forwarding plane. Compared with the CUPS realized by the 4G core network, the CUPS realized by the 5G core network is more thorough, thereby bringing greater flexibility and higher efficiency to the 5G network. The opening of the N4 interface is a key step for finally realizing the CUPS separation.
The N4 interface is opened, and the 5G enabling industry application has many benefits: on one hand, the user can customize the network capacity required by the user to the operator, which is very important for the application of the vertical industry; on the other hand, the 5G trend distributed network can be supported, and the framework of cloud computing and edge computing is further matched, so that the design of 5G + cloud + AI is supported by the network bottom layer technology.
As shown in fig. 1, the UPF creates user session information by receiving a PFCP message of the SMF network element, the UPF network element itself has a primary and secondary protection mechanism (i.e., a primary UPF fails, a secondary UPF takes over the primary UPF function, and the primary UPF and the secondary UPF synchronize user session information in real time), and once the primary UPF fails, the secondary UPF takes over the primary UPF function to become the primary UPF in time, and performs service on the user session information synchronized from the primary UPF.
However, the primary and secondary synchronization of the primary and secondary UPFs requires time and the primary and secondary synchronization may be incomplete, so that the primary and secondary switching is performed, and at this time, the user session information on the switched UPF and the user session information on the SMF may be inconsistent, which may result in that some users may not be served normally.
Accordingly, the prior art is yet to be improved and developed.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 2, the method for detecting a 5G-based SMF session according to the preferred embodiment of the present invention includes the following steps:
step S10, after the primary and standby switching is performed on the original primary UPF and the original standby UPF, the original standby UPF is upgraded to a new primary UPF, and the new primary UPF carries Recovery Time Stamp to the SMF through a report message.
Step S20, after receiving the report, the SMF determines that the original primary UPF has a failure by determining that the Recovery Time Stamp is carried, and the original backup UPF is upgraded to a new primary UPF and the failure is recovered.
Step S30, the SMF issues a modify message for all session information in the new primary UPF, where the modify message carries all data information of the user.
Step S40, after receiving the modify message sent by the SMF, the new master UPF determines whether a session exists in the new master UPF.
And step S50, if the answer is yes, the new main UPF replies a modify response to the SMF.
And step S60, if the answer does not exist, the new primary UPF replies a modify response failure to the SMF, and after the SMF receives the modify response failure, the SMF judges that the session is abnormal in the new primary UPF.
Specifically, as shown in fig. 3, after the primary and standby upsets are performed on the original primary and standby UPFs, the original standby UPF is upgraded to a new primary UPF, and then a report path of report (report information) is sent to the SMF. After receiving the report information sent by the new primary UPF, the SMF considers that the original primary UPF has a failure and the original backup UPF has been upgraded to the new primary UPF, and then determines that the UPF has a failure recovery (the original primary UPF and the original backup UPF are switched, the original primary UPF has failed, and the original backup UPF is upgraded to the new primary UPF, which indicates that the failure has recovered).
The SMF sends a Modify message to all session information (PDU session information) under the new main UPF, carries all data information of the user (the session information sent to the original main UPF), the new main UPF receives the Modify message sent by the SMF, and if the session exists in the new main UPF, the new main UPF replies a Modify response to the SMF successfully. If the session does not exist in the new primary UPF, the new primary UPF replies a modify failure response to the SMF, and the SMF receives the modify failure response and the error code 65 (the session does not exist), and then the SMF considers that the session is abnormal in the new primary UPF, and the SMF can normally and timely detect the abnormal session of the new primary UPF.
