Abstract
This invention relates to a local access network for mobile telephone units. Each radio station in this network has an associated group of radio stations forming a predetermined macrocell. Each radio station may become the macrocell's core station. When a mobile unit leaves the coverage of one station (the “fading” station) and enters the coverage of another (the “change-over” station), virtual connections are formed to the stations covering the macrocell associated with the change over the station. At this time the virtual connections belonging to the stations in the macrocell associated with the previous station, but not belonging to the macrocell associated with the change-over station, are released.
