Radiotelephony network with multi-carrier packet data transmission

The present invention relates to a radio telephone network (1) providing at least one link of the radio channel 6 for the packet data transmission service. The radio telephony network 1 comprises a plurality of network controllers (RNC). Each network controller (RNC) is an interface to at least one radio base station (B-node) to monitor at least one of the micro cell (5a) (Iub) Are each connected via a. The radio telephone network (1) is the same type of interface that is connected to the network controller (RNC) of the radio base station (B-node) (Iub) Further comprises at least one micro radio base station (B1-micro-node) connected to a network controller (RNC) via a. It said micro wireless base station (B1-micro node) monitors at least one microcell (5b) coupled to the at least one micro-cell (5a). Said micro wireless base station (B1-micro node) uses a multi-carrier radio access is preferably provided to the packet data transmission service in said microcell (5b) on the link of the radio channel (6). The multi-carrier radio access is preferably an OFDM format.
