Cross-border roaming code number control method, device and system

Abstract

The invention discloses a cross-border roaming code number control method, device and system. The method comprises the steps that when an eSIM terminal performs cross-border roaming, the eSIM terminal is connected with a roaming place operator to log in the network; the eSIM terminal sends a request for obtaining code number information and certificate information to an eSIM card through roaming place code number downloading guidance, receives the code number information and the certificate information returned by the eSIM card, and sends the code number information and the certificate information to a roaming place operator; the roaming place operator carries out code number judgment according to the code number information and the certificate information, and if the code number is a local code number, a response of allowing local code number profile downloading is returned to the eSIM terminal; if the code number is a cross-border number and the user level in the certificate information is higher than the security level, a response that the downloading of the roaming place code number profile is not limited is returned to the eSIM terminal; if the code number is the cross-border number and the user level in the certificate information is lower than the security level, the eSIM terminal is limited to download the roaming place profile. By adopting the technical scheme of the invention, malicious frequent downloading of the roaming destination code number is avoided.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method, device and system for controlling cross-border roaming numbers. Background technique [0002] With the development of eSIM technology, its application scenarios are becoming more and more extensive. For example, terminals used in Internet of Things devices use eSIM (Embedded Universal Integrated Circuit Card) technology to connect to roaming servers during cross-border roaming, download and activate Using the roaming profile, some terminals will also choose to download and use another home code number that is more suitable for international roaming when roaming across borders. In the prior art, China and foreign countries do not strictly control the number of eSIM online download numbers and the real-name system. At present, China only requires the real-name system, and there is no clear requirement for the number of code numbers downloaded. [000...

Problems solved by technology

[0003] If some criminals take the opportunity to maliciously and frequently download the attribution profile, use the downloaded attribution number without real-name authentication to send junk electronic messages and communication information, and carry out fraudulent activities, it will pose a great threat to the property safety of citizens; On the other hand, if it frequently downloads roaming numbers, it will cause a large amount of confidential data to be downloaded to the eSIM card, which poses a serious threat to social information security.
