Embodiment Construction

[0058] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0059] Those skilled in the art should understand that the present invention is applicable to any communication network in which base stations and terminals interact to perform operations. Preferably, the present invention is applicable to narrowband Internet of Things.

[0060] As used herein, the term "user equipment" or "UE" may be synonymous with user equip...

Abstract

The invention aims to provide a method, device and system for access control. According to the invention, acquisition of user equipment for access control information is controlled mainly through introducing access control activation indication to a base station end and a user equipment end, and then the user equipment is enabled to perform access control according to the acquired access control information. Compared with the prior art, a change notification mechanism for access control is enabled to take effect quickly and lose effectiveness smoothly, update and deactivation for the access control information at any time are support, the real-time performance of the acquired access control information is ensured by relying on specific equipment movements, and the workload of the user equipment for acquiring the access control information is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to an access control technology. Background technique [0002] Narrowband Internet of Things (NB-IoT) is a new feature emerging in 3GPP, which is used to provide wireless access specifications for mobile Internet of Things (cellular IoT). Access control mechanisms for NB-IoT are still open. [0003] Under certain conditions, such as random access burst / congestion, it is necessary to prevent UE (User Equipment, user equipment) users from making access attempts. Available radio access control mechanisms such as ACB (Access Barring, Access Barring) and EAB (Extended Access Barring, Extended Access Barring) are defined in 3GPP to solve the above problems. [0004] However, both EAB and ACB have certain defects: [0005] EAB is dedicated to MTC (Machine-Type Communications, machine-type communication), which detects based on the access category. This method requires the network to n...
