FIELD: radio communications.
SUBSTANCE: radiocommunication circuit may be used in universal mobile telecommunication system (UMTS), which provides packet data transfer service, such as multimedia broadcasting/multi-address service (MBMS) for one or more users with modification (increase) of some existing radiocommunication protocols with usage of new transport channel (descending jointly used channel with one-to-many connection "multi-address DSCH") and/or setting of new jointly used physical descending channels [physical descending jointly used controlling channel (C-PDSCH) and physical descending jointly used channel for data transmission (D-PDSCH)]. Radio channel control level (RLC) is provided in the single radio network controller (CRNC) in such a way, that one and the same MBMS service may be transmitted to a set of terminals through "multi-address DSCH" without repeated provision of a set of RLC levels in many radio network controllers (CRNC). Or, physical descending jointly used control channel (C-PDSCH) and physical descending jointly used data transmission channel (D-PDSCH) are set up to provide regular transmission of MBMS service, allowing users to access one or more MBMS services simultaneously.
EFFECT: increased efficiency.
