FIELD: radio engineering and communications.
SUBSTANCE: invention relates to radio communication technologies and, in particular, to data transmitting method. Method of data transmitting comprises stages, at which: receiving message on creation or updating of PDP-context or unidirectional channel, transmitted by transmitting unit, wherein creation or updating message carries service parameter quality; and based on service parameter quality determining, whether unidirectional channel user tunnel plane data, corresponding to PDP-context, or unidirectional channel user tunnel plane data can be encapsulated into data transmission protocol packet, having high resistance to packets errors by means of UDP-Lite protocol, applied to data transmission packets and returning response message to transmitting unit carrying information on determination result, so, that if information on determination result indicates, that encapsulation can be made by UDP-Lite protocol, encapsulating at transmitting end unidirectional channel user tunnel plane data, corresponding to PDP-context, or unidirectional channel user tunnel plane data, into data transmission protocol packet, having high resistance to packets errors by means of UDP-Lite protocol, applied to data transmission packets.
EFFECT: technical result consists in improvement of data transmission efficiency.
