    摘要: A dynamic AP grouping method and a dynamic AP grouping device are provided. It is able to provide services to UE in a UE-centered manner as compared with a traditional mode where the services are provided to the UE in a network-centered manner, thereby to prevent the UE from frequently acquiring a network environment, and provide the data transmission service to the UE at a low speed or in a stationary state through APGs. In addition, during the movement of the UE, it is able to transmit the services to the UE through dynamic refresh of APs in the APGs and coordination of the APs in the APG. It is able to reduce the number of handover operations made by the UE, and perform the handover operation in the APG not through a core network, thereby to reduce signaling load of a core network.

    摘要: 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.
