1. A method in a User Equipment (UE) of radio link failure recovery comprising:

  • selecting a backup cell from among a set of neighbouring cells that includes a target cell, wherein the backup cell is not the target cell and is to be used for reconnecting to a cellular telecommunication network in case an impending handover of the UE from a serving cell to the target cell fails;

    storing cell access information for the target and backup cells, said cell access information providing the UE with information needed for establishing a connection to the cellular telecommunication network in either the target cell or the backup cell; and

    if the handover to the target cell fails, using the stored cell access information to reestablish connection with the cellular telecommunication network in the backup cell.
