Problems solved by technology

Therefore, the above random access mechanism can only deal with the congestion of a single random access channel of each base station, but cannot deal with the congestion of multiple random access channels as a whole at the same time
[0005] In view of this, how to solve the problem that the above random access mechanism can only deal with the congestion of a single random access channel provided by each base station will be an important purpose in the technical field of the present invention

Abstract

A base station determines at least one access class barring parameter based on load balance of a plurality of random access channels, and broadcasts the at least one access class barring parameter. Acommunication terminal receives a plurality of access class barring parameters from at least one base station, and then determines a random access channel candidate from the random access channels according to the access class barring parameters and performs a random access procedure on the random access channel candidate. Such an access class barring method can efficiently improve traffic congestions of a plurality of random access channels.

Description

technical field [0001] The invention relates to a base station, its access level restriction method and a communication terminal. More specifically, the present invention relates to a base station for improving the congestion of multiple random access channels, its access level restriction method, and a communication terminal. Background technique [0002] In an environment with high-density deployment of communication devices, such as under the machine-to-machine (M2M) communication architecture or under the Internet of Things (IoT) communication architecture, when a large number of communication devices When accessing a base station, the base station will face problems such as congestion and overload. In order to solve these problems, the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) has proposed a technology called Long-Term Evolution (LTE-A) for Long-Term Evolution (LTE-A) Access Class Barring (ACB) random access mechanism. [0003] Und...
