Maintaining the composition of transferred data during handover

摘要: In a radio data transmission system which transmits in cell form, the risk of loss or out-of-ordering during handover can be diminished by synchronizing between new (50) and old (40) base stations. The station delivers to and/or switch (51), information on last that was transmitted successfully right order through station, whereby continues starting from first failed cell. Cells need not identified one if group numbering is applied given (31, 32, 33, 34) counter numbered, rest indicated, where necessary, counting distance numbered
