A method in a radio network that includes a device, the method comprising: obtaining, by the device, a service change information associated with a cell in the radio network, which service change information indicates that the cell in the radio network is out of service; and which method is characterized in identifying, by the device, helper cells (410-1/410-3) in the radio network that need new random access channel RACH parameters because the cell in the radio network is out of service; triggering, by the device, a RACH parameters reconfiguration (460-1/460-3) for a particular helper cell (410-1/410-3) based on received information; configuring, by the device, the particular helper cell (410-1/410-3) with the RACH parameters reconfiguration (460-1/460-3); wherein triggering the RACH parameters reconfiguration (410-1/410-3) comprises: receiving neighbor cell relation lists associated with cells adjacent to the out of service cell; receiving mobility statistics associated with the out of service cell; determining the particular helper cell based on the neighbor cell relation lists and the mobility statistics; receiving a RACH parameters configuration for the out of service cell; and determining reconfigured RACH parameters, corresponding to extended coverage of the particular helper cell (410-1/410-3), based on the RACH parameters configuration and the determined helper cell (410-1/410-3). obtaining, by the device, a service change information associated with a cell in the radio network, which service change information indicates that the cell in the radio network is out of service; and which method is characterized in identifying, by the device, helper cells (410-1/410-3) in the radio network that need new random access channel RACH parameters because the cell in the radio network is out of service; triggering, by the device, a RACH parameters reconfiguration (460-1/460-3) for a particular helper cell (410-1/410-3) based on received information; configuring, by the device, the particular helper cell (410-1/410-3) with the RACH parameters reconfiguration (460-1/460-3); wherein triggering the RACH parameters reconfiguration (410-1/410-3) comprises: receiving neighbor cell relation lists associated with cells adjacent to the out of service cell; receiving mobility statistics associated with the out of service cell; determining the particular helper cell based on the neighbor cell relation lists and the mobility statistics; receiving a RACH parameters configuration for the out of service cell; and determining reconfigured RACH parameters, corresponding to extended coverage of the particular helper cell (410-1/410-3), based on the RACH parameters configuration and the determined helper cell (410-1/410-3). receiving neighbor cell relation lists associated with cells adjacent to the out of service cell; receiving mobility statistics associated with the out of service cell; determining the particular helper cell based on the neighbor cell relation lists and the mobility statistics; receiving a RACH parameters configuration for the out of service cell; and determining reconfigured RACH parameters, corresponding to extended coverage of the particular helper cell (410-1/410-3), based on the RACH parameters configuration and the determined helper cell (410-1/410-3).
