Abstract:
A method, User Equipment (UE), and first base station serving a first cell for performing an access request by the UE for operatively connecting the UE to a second cell. The UE obtains radio quality parameters indicating quality of radio reception between the UE and the first and second cells. Based on the obtained radio quality parameters, it is determined whether the UE is in a link imbalance zone where the UE has an option to be connected to both the first cell and the second cell. If so, the UE sends access request information, to the first base station and indicates availability of the UE to be redirected to the second cell. The first base station may redirect the UE to the second cell when a load of the first cell meets pre-defined load criteria.
