The invention relates to a method for radio network synchronization of a mobile communication network, wherein the mobile communication network comprises a plurality of base station entities and at least one user equipment connected to the mobile communication network, wherein each of the plurality of base station entities comprises a local clock functionality providing a local timing reference for the respective base station entity, wherein in order for a first base station entity among the plurality of base station entities to obtain an indication about the timing reference of a second base station entity among the plurality of base station entities, a handover procedure is triggered - by the first base station entity and for the user equipment - from the first base station entity to the second base station entity, wherein the method comprises the followings steps: - in a first step, the first base station entity is the serving base station entity for the user equipment and requests the user equipment to execute a handover towards the second base station entity, - in a second step, during the handover procedure of the user equipment towards the second base station entity, a timing information is transmitted from the second base station entity - via the user equipment - to the first base station entity, the timing information being indicative of the local timing reference of the second base station entity, - in a third step, subsequent to the second step, the timing information is used by the first base station entity to adjust the local timing reference of the first base station entity. |
