    摘要： The present invention relates to the wireless network communication field, and discloses a method for handover between multi-carrier cells to avoid repeated handover decisions caused by delay of the triggering event. The method includes: the source cell receives a measurement report triggered by an event reported by a served User Equipment (UE); and the source cell executs a handover decision according to measurement reports triggered by multiple events after receiving the measurement reports triggered by the multiple events within an estimated interval, and hands over the UE to the corresponding carrier of the corresponding target cell. With the present invention, the resources of the source cell and the target cell may be saved, and the handover efficiency may be improved.

    摘要： A method for controlling uplink power of an LTE system, a base station, and a mobile terminal are disclosed according to the embodiments of the present invention. The method includes: obtaining uplink transmit power of each carrier; sending first notification signaling to a base station if a difference between the obtained uplink transmit power of each carrier exceeds a specific threshold; and sending second notification signaling to the base station if a sum of the obtained uplink transmit power of each carrier exceeds a preset threshold. Thresholds are determined according to network conditions, and uplink power of a carrier is adjusted in a balanced way, a bit error rate is reduced and a case that a low-performance carrier is forced to be interrupted is prevented.
