Abstract
A method of operating a base station in a cellular communications network, in which Radio Resource Control (RRC) connected user equipment devices can be kept synchronized with the cell on the uplink or become unsynchronized. The method comprises determining whether a specified condition within a cell served by the base station is fulfilled, and, in response to determining whether the specified condition is fulfilled, determining whether RRC connected user equipment devices should be kept uplink synchronized with the cell, or whether RRC connected user equipment devices should be allowed to become uplink unsynchronized. Signals are transmitted to RRC connected user equipment devices to affect whether or not such devices are kept uplink synchronized with the cell, in response to determining whether RRC connected user equipment devices should be kept uplink synchronized with the cell, or whether RRC connected user equipment devices should be allowed to become unsynchronized on the uplink.
