  • Publication number: 20120230347
    Abstract: 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.

  • Publication number: 20120039204
    Abstract: A radio bearer status sending method and device are provided. The method includes: after executing uplink resource allocation during current transmission period, determining the number of tokens in a token bucket which is corresponding to the radio bearer; according to the determined number of tokens, sending the first status information which indicates that the number of the tokens is larger than zero to a base station; or sending the second status information which indicates that the number of tokens is not larger than zero to the base station. By using the method and device provided by the invention, the accuracy of the radio bearer status reported by a User Equipment (UE) is improved, therefore, the base station can allocate the uplink resources more properly, and the usage efficiency of uplink resources is increased.
