Abstract: The invention relates to a method in a target radio base station (14) for enabling a handover of a connection to a user equipment (13) from a source cell (12) to a target cell (11) associated with a target cell identity. The source cell (12) is served by a source radio base station (15) and the target cell (11) is served by the target radio base station (14). The target radio base station (14) and the source radio base station (15) are comprised in a radio communications network (100) and the target radio base station (14) is adapted to be connected to a gateway node (16) associated with a network node identity. The gateway node (16) is acting as a proxy for the target radio base station (14) towards a core network (17) and towards the source radio base station (15). The target radio base station broadcasts, periodically within the target cell (11) on a radio channel to the user equipment (13), the target cell identity and a mask.
