A kind of fault detection method and device of user plane network element

Abstract

The present application discloses a fault detection method and device for a user plane network element. The method is applied to a user plane network element, and the method includes: sending a detection packet to a peer address, and determining a feedback state of the detection packet; If the feedback state is a fault state, state detection is performed on the communication gateway corresponding to the peer address to determine the fault type; if the fault type is a local fault, a first fault message is determined; the first fault Packet reporting; in a fault state, the corresponding communication gateway of the user plane network element performs status detection to determine the type of fault; this application avoids the generation of fault packets for each communication path when the user plane network element is locally faulty, that is, avoids a large number of inconsistencies. In the case of necessary fault packets, unnecessary fault packet processing is not required, which saves computing resources.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method and device for fault detection of a user plane network element. Background technique [0002] In the 5G core network system, the user plane network element (UPF, full name User Plane Function) can undertake the reliability maintenance task of the relevant communication path; that is, the reachability of the communication path is detected to determine whether the communication state is normal. Further, the user plane network element may report the detection result to a session management network element (SMF, full name Session Management Function), so as to facilitate subsequent processing of the fault. [0003] However, in the prior art, the user plane network element can only judge whether a fault exists through detection, but cannot judge the specific type of the fault. In other words, it is impossible to determine whether the fault comes from ...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing technology, the user plane network element can only judge whether there is a fault through detection, but cannot judge the specific type of the fault.

In other words, it is impossible to judge whether the fault comes from the local network element of the user plane or from the peer end of the communication path

Therefore, some unnecessary fault reports may be brought about, and it is not conducive to the processing of faults.
