Apparatus and method for performing handover in a wireless communication network

摘要

A base transceiver station receives first and second reception power values from a plurality of user equipments. The first reception power value is a reception power value at which a user equipment receives a radio signal from another base transceiver station without using a reception beam formation function that allows a radio signal transmitted from a predetermined direction to be selectively received with increased reception sensitivity. The second reception power value is a reception power value at which a user equipment receives a radio signal from another base transceiver station using the reception beam formation function. The base transceiver station selects, from among the plurality of user equipments, a user equipment to be handed over based on the first and second reception power values, and performs handover processing on the selected user equipment.

1. A base transceiver station for performing handover in a wireless communication network, the base transceiver station comprising:
a processor to:
receive first reception power values from a first mobile user equipment and a second mobile user equipment of a plurality of mobile user equipments communicating with the base transceiver station respectively, each of the first reception power values being a reception power value at which each of the first mobile user equipment and the second mobile user equipment receives a radio signal from another base transceiver station without using a reception beam formation function that allows a radio signal transmitted from a specific direction to be selectively received with increased reception sensitivity, the first mobile user equipment being a mobile user equipment without the reception beam formation function, the second mobile user equipment being a mobile user equipment with the reception beam formation function,receive a second reception power value from the second mobile user equipment, the second reception power value being a reception power value at which the second mobile user equipment receives a radio signal from the another base transceiver station using the reception beam formation function,select, from among the plurality of mobile user equipments, a handover mobile user equipment to be handed over, based on a reception power value that is largest among the first reception power values received from the first mobile user equipment and the second mobile user equipment and the second reception power value received from the second mobile user equipment, and leveling of a communication load of the base transceiver station and another communication load of the another base transceiver station when the communication load is larger than the another communication load, andperform handover processing on the handover mobile user equipment so that the base transceiver station with which the handover mobile user equipment wirelessly communicates is changed from the base transceiver station to the another base transceiver station; and a memory to:
store, the first reception power values, andstore, the second reception power value.
