Abstract:
Method related to a handover decision of a user equipment in a telecommunication system comprising a plurality of cells, each of which served by a corresponding radio base station,the user equipment comprising a measurement set containing cell identities of cells that the user equipment is aware of, said measurement set being subdivided into an active set containing cell identities of cells to which radio base station the user equipment has an established communication link, a control set containing at least the identities of neighbour cells of said cells in the active set, characterised in the user equipment performing the steps of releasing an established communication link to a radio base station of a candidate cell in the active set of the user equipment, if said cell does not comply with one or more decision criterions, and excluding (25,44) the cell identity of said candidate cell from the active set, activating a delay unit (24,26,45) with definable delay period when the cell identity of said candidate cell is excluded from the active set (25,44), excluding the cell identities of cells without at least one neighbour cell in the changed active set from the measurement set not until said delay period has expired (27,46).
