FIELD: information technologies.
SUBSTANCE: in wireless communication systems base station groups multiple doze mode identifiers and sends traffic indication message, which comprises information of the first bitmap, which indicates whether traffic is available that corresponds to corresponding groups of doze mode identifiers, and information of the second bitmap, which indicates whether traffic indicators are available in respect to corresponding doze mode identifiers, which are included into groups of doze mode identifiers. Mobile station, which has one identifier assigned from multiple doze mode identifiers, determines whether traffic is available in group of doze mode identifiers, which comprises mobile station itself, using information of the first bitmap, if mobile station accepted traffic indication message, and using information of the second bitmap, checks indicator of traffic of terminal itself, if traffic is available in group of doze mode identifiers, which comprises mobile station.
EFFECT: ability of base station to send functional message of traffic indication to several mobile stations, which are in doze mode.
