Abstract: The embodiments of the present invention provide a method and a device for detecting a traffic hot spot of a cell. The method includes: acquiring load information of a cell in which a wireless access point AP is located, the load information includes at least two types of the following information: a data rate of user traffic requirement, the number of users associated with an AP, an average length of data packets and an average duration of successful transmissions; determining whether an operating state of the AP is abnormal according to the at least two types of information; determining a satisfaction degree of user according to the actual traffic rate of user, if the operating state of the AP is abnormal; and determining that a traffic hot spot exists in the cell, if the satisfaction degree of user is lower than a first preset threshold.

Abstract: The present disclosure provides an access control method and apparatus, and a network device. The method includes: performing grid partitioning on a target cell covered by a wireless access point, to obtain multiple grids; grouping, based on a neighboring cell of the target cell, grids that satisfy a preset condition in the multiple grids into one or more interference clusters; calculating an access offset of each of the interference clusters; and sending, to a user in each interference cluster, an access offset of a corresponding interference cluster, so that the user selects a cell based on the access offset of the corresponding interference cluster. Grids of a target cell are grouped into interference clusters according to signal to interference plus noise ratios, and an access offset is set for each interference cluster, to ensure service quality and improve user experience.
