Mobile communication network having path selection means for selecting a communication path

摘要

The invention concerns a mobile communication network (MCN) having communication paths (DCMRN, FBS, LE or ICMRN, RS, GCFN/GCRN, FBS, LE) between any one of mobile terminals (MT) and a fixed telecommunication network (FTN). Each communication path (DCMRN, FBS, LE or ICMRN, RS, GCFN/GCRN, FBS, LE) has a radio access link (DCMRN, ICMRN) between a mobile terminal (MT) and a relay station (RS) and has a relay link (GCFN/GCRN) between the relay station (RS) and a fixed base station (FBS). The mobile communication network has path selection means (FBS) for selecting, as part of a hand-over decision, a communication path (DCMRN, FBS, LE or ICMRN, RS, GCFN/GCRN, FBS, LE) between the mobile terminal (MT) and the fixed telecommunication network (FTN) based on measurement data of characteristics of radio access links (DCMRN/ICMRN) included in the possible communication paths (DCMRN, FBS, LE or ICMRN, RS, GCFN/GCRN, FBS, LE). The path selection means (FBS) also bases its selection on measurement data of characteristics of the relay links (GCFN/GCRN) included in the communication paths (DCMRN, FBS, LE or ICMRN, RS, GCFN/GCRN, FBS, LE).
