Abstract: The present invention discloses a method, a network device, and a user equipment for controlling access to a core network. The method includes: determining that a change occurs in access control information for controlling a user equipment to access a core network; and sending radio resource control signaling to the user equipment through a dedicated control channel, where the radio resource control signaling is used to notify the user equipment that a change occurs in the access control information, so that the user equipment updates the access control information. Therefore, a load of a core network node can be effectively controlled, and system performance is improved.

Abstract: Embodiments of the present application provide a method for determining a transmission time interval, a base station, and a radio network controller. A base station receives uplink data sent from a user equipment in an idle state or a cell forward access channel state on an enhanced dedicated transmission channel. The base station determines a transmission time interval (TTI) used by the user equipment for sending the uplink data, and sends the uplink data and a transmission time interval indicator in an enhanced dedicated transmission channel data frame to a radio network controller. The radio network controller acquires the TTI, thereby ensuring that the radio network controller selects and configures an appropriate TTI for the user equipment when the user equipment transits from the Cell_FACH state to the Cell_DCH state.

Abstract: A user equipment (UE) communication method, a device, and a communications system are provided. A first UE sends a notification message to a cellular network access device, wherein the notification message indicates that the first UE requests to be a beacon device. The first UE receives, from the cellular network access device, a message indicating that the first UE is the beacon device. The first UE sends detection signal, wherein the detection signal is for a second UE to detect the detection signal.

Abstract: The present invention discloses a multiple users cooperative communication (MUCC) method and system. The main idea of the present invention is as follows: through multiple users cooperative communication between APs, data to be sent to a UE by an eNB may be sent to a support AP at first, and then the support AP sends the data to the UE; and when the support AP is in a poor network environment, the eNB may send the data to other APs near the support AP, and finally forward the data to the support AP through one or more times of forwarding between other APs. The present invention has a multiuser diversity gain without increasing the complexity and power consumption of the UE; furthermore, a laying cost of wired backhaul can be reduced and reliability and transmission efficiency of MUCC can be improved.
