Abstract: Embodiments of the present invention relate to the technical field of wireless communications, and in particular to an access control method and device, for use in resolving the problem in the prior art that a user equipment cannot securely access an access points group (APG). According to the embodiments of the present invention, when a user equipment needs to access a network, the user equipment conducts network-layer two-way authentication with a local service center; after the network-layer two-way authentication succeeds, the user equipment conducts access-layer two-way authentication with a corresponding APG so as to enable the user equipment to access the corresponding APG after the access-layer two-way authentication succeeds. The embodiments of the present invention use dual-layer two-way authentication, and enables the user equipment to access a corresponding APG after the dual-layer two-way authentication succeeds, so that the user equipment can securely access the corresponding APG.

Abstract: The present invention relates to the technical field of wireless communications, and in particular, to a beam training method and device, for use in resolving the problems in the prior art of excessive time-consuming of a beam training process, large overhead of training signals, and relatively low efficiency. According to embodiments of the present invention, a transmit device sends beam training signals in two times. The first sending of a transmit beam training signal is for a receive device to select a transmit beam using a selected receive beam and report the transmit beam. The second sending is that the transmit device sends a receive beam training signal according to the transmit beam information report of the receive device, so as to train the received beam of the receive device. According to the embodiments of the present invention, an interactive beam training method is used to gradually search for the best transmit beam and receive beam, thereby avoiding completing beam training all at once, reducing beam training time and overhead, and improving efficiency.
