1. A method for use in a wireless cellular telecommunications system in which system there is a plurality of cells each of which can accommodate a number of users with mobile terminals (MSs), and in which system there is also a plurality of Base Stations (BSs) with the traffic to and from the MSs in a first cell being routed via a first BS and in which system an MS can be handed over from said first BS to a second BS of a second cell in the system, comprising the steps of:
informing, by the second BS to the first BS that an update has taken place in the system information of the second BS, wherein the informing step occurs independently of a determination that one or more MSs is to be handed over from said first BS to said second BS; acquiring, by the first BS, the updated system information of the second BS; transmitting, by the first BS, at least part of the updated system information of the second BS to MSs in the cell of the first BS; and wherein the updated system information comprises an updated Configuration Change Counts (CCC) of one or more of a control message for an uplink and a control message for a downlink; and wherein said updated system information is requested by the first BS from the second BS as a result of a message from the second BS that its system information has been updated.
