Abstract: Embodiments of the present invention provide a method and a device for synchronizing an uplink ciphering parameter in unacknowledged mode. The method for synchronizing an uplink ciphering parameter in unacknowledged mode includes: sending an indication message to a terminal when detecting that an unrecoverable error occurs in an uplink packet or that the uplink packet is invalid, where the indication message is used to instruct the terminal to initialize an uplink ciphering parameter; receiving a response message sent by the terminal; and initializing the uplink ciphering parameter according to an initial value of the ciphering parameter. The embodiments of the present invention solve a service defect, namely, a break of the communication link caused by synchronization of an uplink ciphering parameter between the terminal and the radio network controller in unacknowledged mode, and shorten the time of synchronizing the uplink ciphering parameter without interrupting the service.

Abstract: The present application discloses a data transmission method, including: sending at least two groups of same data to user equipment; and instructing the user equipment to perform softer combination on the received at least two groups of same data. Embodiments of the present application further provide a corresponding apparatus, including: a base station, user equipment, and a radio network controller. In the technical solutions of the present application, because the user equipment is instructed to process received data in a softer combination manner, reliability can be improved, and a call drop rate can be reduced.

Abstract: Embodiments of the present invention provide an MDT control method, system, and network element device. The network element device acquires an MDT PLMN list, where the MDT PLMN List includes at least two PLMN identities, and UEs in at least two PLMNs corresponding to the at least two PLMN identities can perform MDT in the at least two PLMNs; when a first UE accesses a current PLMN, the network element device acquires and determines that a user intention of the first UE is to permit performing the MDT; the network element device judges whether the MDT PLMN List includes an HPLMN identity or an EHPLMN identity of the first UE; and when the MDT PLMN List includes the HPLMN identity or EHPLMN identity of the first UE, the network element device instructs the first UE to perform the MDT measurements.
