Abstract
A method for a cellular network (100) comprising cells (110) of a first kind controlled by corresponding base stations (111), and cells (120-122) of a second kind controlled by corresponding base stations (125-127). The second kind of cells are smaller than the first kind of cells (110). The network (100) comprises functions (140) for control of the base stations, and functions (150) for handing over the control of user terminals (123, 112) between base stations. The method is used when a call in a cell of the second kind (120-122) is handed over to a base station of the first kind. The method lets said control function (140) of the base station of the cell of the second kind send identifying information to the control function (140) of the base station (111) of the first kind, such that if the call is to be handed back to the original base station (125-127), the original base station can be found by the network.
