The present disclosure discloses a cell change method, a terminal, and a network device. By implementing this application, a problem that a receiving success rate of the change command cannot be improved when the another intra-frequency measurement event except the event 1D is triggered can be resolved.

Cell change method, terminal, and network device

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.

The present disclosure, relating to the field of communications technologies, discloses a method, an apparatus, and a system for relocating a user equipment between radio network controllers. The present disclosure is directed to configuring the coding scheme configured for the user equipment UE to a coding scheme consistent with the coding scheme supported by a target radio network controller to relocate the UE to the target RNC. The present disclosure is mainly applicable to inter-RNC handovers.

Method, apparatus and system for relocating user equipment between radio network controllers

Embodiments of the present invention provide a method, a terminal device, a network-side device, and a communications system for managing a power supply. The method includes: determining a terminal power consumption level according to remaining power or terminal settings, where the terminal power consumption level is one of at least two power consumption levels. In the embodiments of the present invention, different power consumption levels are applied according to different remaining power of a terminal power supply or terminal settings, thereby adapting to differentiated power consumption requirements and improving the power supply utilization efficiency of a terminal.
