  • Patent number: 9526033
    Abstract: Embodiments of the present invention disclose a method and network side device for reducing handover signaling. The method includes: determining, by a network side device, a handover frequency of an inactive user equipment in a first preset time; and when the handover frequency is larger than or equal to a predetermined threshold, sending, by the network side device, a message to the inactive user equipment, so that the inactive user equipment enters a radio resource control idle state. In solutions of the embodiments of the present invention, when a handover frequency reaches a certain value, a user equipment is set to an RRC idle state; therefore, the quantity of handover signaling during a movement process of an inactive user equipment may be reduced, and an overhead of handover signaling is reduced, thereby reducing power consumption of the user equipment and improving power saving performance of the user equipment.

  • Patent number: 8971228
    Abstract: The present invention applies to the field of communications, and provides a method for configuring parameters, a base station and a user equipment. In a method, a user equipment (UE) obtains discontinuous reception (DRX) parameters from a base station. The DRX parameters are obtained when a service type of the UE is a sparse packet service. The UE performs DRX control according to the DRX parameters.

  • Patent number: 8582483
    Abstract: The present invention applies to the field of communications, and provides a method for configuring parameters, a base station and a user equipment. In the method, a base station determines whether a service type of a user equipment UE is a sparse packet service. The base station, determines discontinuous reception DRX parameters of the sparse packet service when the service type of the UE is the sparse packet service. The base station sends the DRX parameters to the UE. The DRX parameters are used by the UE to perform DRX control.
