HANDOVER METHOD BASED ON UPLINK SIGNAL, METHOD FOR CONFIGURING UPLINK SIGNAL, USER EQUIPMENT AND BASE STATION

摘要

A handover method based on an uplink signal, a method for configuring an uplink signal, UE and a base station. The handover method includes: transmitting, by a source base station, a triggering message to the UE, to trigger the UE to transmit an uplink signal for handover; receiving notification message(s) transmitted by one or more other base station(s) according to detection of the UL signal; and determining a target base station from the one or more other base station(s) according to the notification message(s), and performing handover of the UE. It is possible to accelerate judging of handover based on measurement of an UL signal, to satisfy handover demand in different scenarios.

1. A base station, configured in a communication system where UE is handed over from the station to a target base station, wherein the base station comprises:
a message transmitting unit, configured to transmit a triggering message to the UE, to trigger the UE to transmit an uplink signal for handover; a notification receiving unit, configured to receive notification message(s) transmitted by one or more other base station(s), wherein the notification message is transmitted according to detection of the uplink signal; and a handover unit, configured to determine the target base station from the one or more other base station(s) according to the notification messages, and perform handover of the UE.
