Method, device and system for access control

Abstract

The embodiment of the invention discloses a method, a device and a system for access control. The method comprises the following steps of: receiving an access request; acquiring access right information of user equipment (UE) or a group to which the UE belongs or an access point name (APN) which sends the access request; executing access operation if the access right information is in accordance with access grant condition; refusing access operation if the access right information is not in accordance with access grant condition, and determining that the UE or the group to which the UE belongs or one APN is illegal; and sending the UE or the group to which the UE belongs or some one APN as the illegal information to a server. By judging the access right information of the network side UE or the group to which the UE belongs or the APN, accessing the UE in accordance with the access grant condition, and sending the UE or the group to which the UE belongs or some one APN as the illegal information to the server, the method achieves the aim of limiting the access of the UE, further prevents the UE from maliciously attacking the network side and improves network service quality.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an access control method, device and system. Background technique [0002] With the popularization and development of wireless communication technology, a large number of terminals have emerged, such as Machine Type Communications (MTC) applications; in MTC, a network between one or more network elements without human participation Communication, that is, machine-to-machine (M2M) applications; specific application scenarios such as: traffic control and management, factory monitoring, remote meter reading, etc. In MTC applications, user equipment (User Equipment, UE) is called M2ME in MTC applications, and multiple M2MEs form a whole, which can be called a group. Network operators or industry users can manage or control the group as a whole. The group identifier of can be used to identify and distinguish different groups. Network operators and industry users can p...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that: when an illegal UE viciously attacks the network side or uses an illegal access point name (Access Point Name, APN) to viciously attack the network, the network side cannot well prevent the illegal UE from continuing to attack other network entities , and the network side does not investigate illegal causes of illegal UEs, resulting in more and more illegal terminals emerging, which poses a great threat to network security and seriously affects the experience of other normal users
