Abstract:
1. A method for determining, in a wireless cellular telecommunication network, if a handover of a first half-duplex terminal has to be executed from a first base station to a second base station, each base station transferring signals in a respective cell, the first half-duplex terminal, when being handled by a base station, not transferring and not receiving signals during a period of time, called idle period of the cell of the base station which handles the first half-duplex terminal, the method, executed by the first base station, comprising steps of: transferring signal in the cell of the first base station; receiving a message transferred by the first half-duplex terminal in response to the signal transferred by the first base station, the message comprising information relative to quality measurements on the signal transferred by the first base station and at least quality measurements on the signal transferred by the second base station; receiving a message indicating if the idle period of the cell of the second base station is compatible with the round trip delay of the first half-duplex terminal in the cell of the second base station; and determining if a handover of the first half-duplex terminal has to be executed from the first base station to the second base station according to the compatibility of the idle period of the cell of the second base station with the round trip delay of the first half-duplex terminal in the cell of the second base station and the information relative to quality measurements.
