Abstract
In a cellular communications network including microcells and macrocells, a mobile device preferably communicates with an appropriate one of the microcells. When a handover from one microcell to another is imminent, a backup channel in the macrocell layer is allocated to the mobile device, for use if the handover is not successfully completed.
