AI Technical Summary

Technical Problem

When a general-purpose integrated circuit card connects to a new network in the switch area, it may lack the certificate chain that presets the corresponding network in the area, and the certificate is stored for too long, or the certificate is revoked, resulting in the inability to access the network normally, which makes the mobile device unable to communicate.

Method used

Through communication between the proxy server and the enhanced user management server, respond to the network access failure request of the general integrated circuit card, obtain its electronic card information, send a certificate application request to the enhanced user management server, determine the target certificate, and send the target certificate to the general integrated circuit card to update the current certificate.

Benefits of technology

It realizes rapid update of general-purpose integrated circuit card certificates, ensuring that mobile devices can access the new network normally and restore communication functions.

Abstract

The invention relates to a certificate updating method, device and system of a universal integrated circuit card and a medium. The method is applied to a proxy server, and comprises the following steps: in response to a network access failure request sent by a universal integrated circuit card, obtaining electronic card information of the universal integrated circuit card; sending a certificate application request to an enhanced user management server based on the electronic card information, so that the enhanced user management server determines a target certificate of the universal integrated circuit card based on the certificate application request; and sending the target certificate of the universal integrated circuit card to the universal integrated circuit card, so that the universal integrated circuit card updates the current certificate to the target certificate. Therefore, through communication among the universal integrated circuit card, the proxy server and the enhanced user management server, certificate updating of the universal integrated circuit card can be realized, the method is simple and rapid, the universal integrated circuit card can be conveniently and normally accessed to a new network, and the mobile equipment can normally communicate based on the updated certificate.
