FIELD: rendering services for data transfer in mobile communication systems. ^ SUBSTANCE: new architecture is proposed for transfer of multimedia data of various qualities of services in mobile communication system. Novelty in protocol structure is that communication line protocol layer receives data of various qualities of services and divides data into datagrams according to quality of service; multiplexing layer multiplexes datagrams received from communication line protocol layer and outputs multiplexed data of transport units; quality control channel receives multiplexed data of transport units and outputs the latter with quality of service by means of perforating and repeating information added in compliance with quality of service for multiplexed data of transport units. ^ EFFECT: provision for rendering multimedia services of different quality. ^ 22 cl, 11 dwg |
