Cell access control method, device and base station

Abstract

The invention provides a cell access control method and device and a base station, and the method comprises the steps: receiving an access request of target UE; and under the condition that the continuous access failure times of the target UE reach the target times, sending an SIB1 message carrying the information of the target time period to the target UE, so that the target UE does not initiate an access request in the target time period, wherein the access request is used for requesting to access the target cell. According to the cell access control method, the cell access control device and the base station provided by the embodiment of the invention, the SIB1 message carrying the information of the target time period is sent to the target UE under the condition that the number of continuous access failures of the target UE reaches the target number, so that the target UE does not initiate an access request in the target time period, frequent access of illegal UE and UE with poor signal quality can be avoided, the waiting time of legal UE is increased, the access load of a base station can be reduced, and the normal service of the legal UE can be better ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a cell access control method, device and base station. Background technique [0002] The number of UEs (User Equipment, User Equipment) that can be accommodated by a single cell (Cell) of a base station is always limited. The general practice of wireless communication systems in access control (AC, Access Control) is generally achieved through the number of UEs, the number of DRB (Data Radio Bearer, data radio bearer), and the rate of GBR (Guaranteed Bit Rate, guaranteed bit rate) Incoming UEs are controlled to prevent exceeding the upper limit of services that the cell can provide and impact existing UEs. However, existing access control methods still result in saturated access. [0003] Saturated access can be divided into the following scenarios: The first scenario is that a large number of legitimate UEs reside in a certain cell and perform wireless access. T...
