Inter base station handover method, radio communication system, DRX control method, base station, and communication terminal

摘要

The present invention provides a DRX control method and system in which power consumption of a mobile station can be reduced and an increase in the load of a network can be suppressed. A source base station forwards Dormancy Context, which is information for controlling the activity level of a mobile station that performs inter base station handover, to a target base station and, immediately after the mobile station completes handover, the target base station performs DRX control of the mobile station using the Dormancy Context.

主权项

1. A mobile station, comprising:
a receiver configured to receive signals; and a controller configured to use at least one of a first Discontinuous Reception (DRX) configuration or a second DRX configuration having longer DRX cycle than a DRX cycle of the first DRX configuration, wherein the controller is further configured to start to use the second DRX configuration if the mobile station does not receive data within a predetermined period while using the first DRX configuration.
