Claim:
1. A method in a network node for allocating to user equipments a respective carrier, which carrier is a frequency carrier for wireless communication, and which network node is comprised in a cellular network, the method comprising: establishing geographic handover regions of cells for different carriers in the set of carriers, by correlating handover events of user equipments between cells, with respective locations of the user equipments and respective carriers being used, or by cell measurement reports that are provided by user equipments from different locations of the cells; identifying a set of carriers, which carriers in the set of carriers each is associated with a respective geographic handover region for handover between the cells, which the geographic handover regions of the carriers differ from each other more than a threshold, identifying a group of user equipments with correlated mobility pattern, and allocating to at least two of the user equipments within the group of user equipments respective different carrier in the set of carriers, such that the at least two user equipments in the group are spread among the carriers in the set of carriers.
