FIELD: wireless communication systems.
SUBSTANCE: preferable alternative of proposed system is GSM/EDGE standard radio access logic link control (LLC) network that has interrelated mobile-station level and LLC level of serving GPRS support node (SGSN); serving GPRS support node and set of base stations being interrelated through Gb interface. System functions to establish and use plurality of time-base data-unit flows (TBF) to transfer packet data units (PDU) in direction of return communication line or direct communication line between mobile-station LLC level and SGSN node LLC level. System operates at LLC level and at radio link control (RLC) level to differentiate PDU related to first TBF from PDU related to second TBF basing on information related to each PDU and displays PDU on one of respective first TBF and second TBF basing on this information.
EFFECT: enlarged functional capabilities of system.
