Disclosed are reporting and controlling methods for DRX (Discontinuous Reception) parameter and terminal moving velocity and devices thereof, which are used to decrease the network resource wasting and reduce the terminal power consumption. The reporting and controlling method for DRX parameter includes the following steps: the network side sends indication information which indicates whether the terminal is permitted to report DRX reference parameter or DRX parameter configuration advice to the terminal, and the indication information is used to indicate the terminal to report DRX reference parameter or DRX parameter configuration advice when it receives the indication for permitting reporting reference parameter or DRX parameter configuration advice, and not report DRX reference parameter or DRX configuration advice when it receives the indication for not permitting reporting reference parameter or DRX configuration advice. The method for reporting and controlling terminal moving velocity includes the following steps: sending indication information which indicates whether the terminal is permitted to report moving velocity to the terminal, or sending indication information which indicates the terminal to report moving velocity when it switches from idle state to connection state to the terminal.

The present disclosure relates to the field of mobile communication technology, and provides a method for implementing discontinuous reception and a base station. The method includes the steps of: receiving, by a first base station, a discontinuous reception DRX configuration recommendation reported by UE; and transmitting, by the first base station, the DRX configuration recommendation or DRX configuration parameters configured by the first base station for the UE in accordance with the DRX configuration recommendation to a second base station when the UE is switched from the first base station to the second base station.

The embodiments of the present invention disclose a method and user terminal for receiving multicast control channel (MCCH) change notifications, which include: obtaining the transmission time of an MCCH change notification; and when the MCCH change notification is not received during one MCCH modification period, receiving, according to the transmission time of the MCCH change notification, the MCCH change notification at least N times, wherein N is the preset reception times of the MCCH change notification. In the present invention, the efficiency of receiving MCCH change notifications by user terminals is improved, and the probability of processing MCCH change notifications falsely due to too many network identifiers in a physical downlink control channel (PDCCH) is reduced.
