摘要

The invention relates to a method for improving overall network performance and/or overall quality of service of user equipments in a mobile communication network, wherein the mobile communication network comprises a core network and an access network, wherein the access network comprises at least one base station entity serving the user equipment, wherein a serving radio cell is associated to the base station entity corresponding to the radio coverage area of the base station entity, wherein further radio cells are located in the vicinity of the serving radio cell, wherein the serving radio cell as well as the plurality of further radio cells use, respectively, a center frequency, wherein a physical cell identifier information as well as a cell global identifier information is assigned, respectively, to the serving radio cell and to each of the further radio cells, wherein in case that the user equipment requests a handover to be performed towards a target radio cell based on indicating both the target physical cell identifier information and the target center frequency of the target radio cell, and additionally, in case that at least two radio cells of the further radio cells have the identical target physical cell identifier information and the identical target center frequency such that a determination of the correct target radio cell among the at least two radio cells of the further radio cells is not possible based on solely the target physical cell identifier information and the target center frequency of the target radio cell, the method comprises the following steps: in a first step, the base station entity – prior to executing the requested handover procedure – requests the user equipment to decode the cell global identifier of the target radio cell, in a second step, subsequent to the first step, the user equipment reports the cell global identifier to the base station entity, in a third step, subsequent to the second step, the base station entity determines which one of the at least two radio cells of the further radio cells, having the target physical cell identifier information and the target center frequency, corresponds to the target radio cell, and initiates the handover procedure towards the target radio cell.
