Method and network node for handling handover
First 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, andallocating 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.

Abstract
A method in a network node for allocating to user equipments a respective carrier is provided. The carrier is a frequency carrier for wireless communication. The network node is comprised in a cellular network. The network node identifies (202) a set of carriers. The carriers in the set of carriers each are associated with a respective geographic handover region for handover between cells. The geographic handover regions of the carriers differ from each other more than a threshold. When the network node has identified (203) a group of user group of user equipments with correlated mobility pattern, it allocates (204) to at least two of the user equipments within the group of user equipments a respective carrier. The allocation is performed such that the at least two user equipments in the group are spread among the carriers in the set of carriers.
