Network access abnormity processing method and device, computing equipment and storage medium

Abstract

The invention discloses a network access abnormity processing method and device, computing equipment and a storage medium. The method comprises the following steps of monitoring whether an attachment request initiated by a user terminal passes verification or not, if the verification fails, requesting subscription data corresponding to the user terminal from the HSS according to the abnormal verification information, and analyzing the subscription data returned by the HSS to obtain an abnormal analysis result, and according to the abnormal analysis result, resetting the subscription data, and initiating a detachment request to the MME, so that the MME removes the user terminal according to the detachment request and notifies the user terminal to initiate the attachment request again. The operation and maintenance mechanism of 'predictive maintenance' is adopted in the 5G network to actively preprocess the access abnormity of the 5G network, that is, the network abnormity is responded at the first time in a mode of active intervention when the abnormity of the attachment request applying for network access is monitored, so that the economic and social influences caused by network hidden dangers or faults are reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device, computing device and storage medium for processing abnormal network access. Background technique [0002] With the deployment of 5G core networks and the generalization of 5G application access requirements, users have increasingly rich requirements for data access terminal types, access quantities, and uplink and downlink data transmission quality. Abnormal problems that lead to inability to access the Internet. For example, if the Access Point Name (APN) is signed at the same time as CMNET and the Context-ID is 234 (4G data template) and 1002 (5G data template), the attachment will fail and the Internet cannot be accessed. And other issues. [0003] However, for the current analysis and handling of the abnormal state of 5G services, there is no active discovery and intervention mechanism on the network access side, and the user can only perceiv...

AI Technical Summary

Problems solved by technology

Since the analysis and handling methods for the abnormal state of 5G services in the prior art are mostly passive maintenance modes of "waiting for alarm" and "waiting for complaints", while online services have high requirements for timeliness, and abnormal complaints are made in the passive maintenance mode on the network side The disposal process is long, the timeliness is poor, and the influence of public opinion is large; in addition, the network networking mode is complex, forming a "five domains and ten networks" structure, which affects many online business links, manual full-process analysis is difficult, takes a long time, and multi-professional cross-device Troubleshooting is very difficult, and it is easy to cause problems that are difficult to locate and slow to reduce user perception
