Invention refers to methods of data transfer, in particular-for transferring of multimedia data to user's stations with two-sided mode, for example-when user sends a signal of program (content) choice, and can be used in multiservice networks of digital data transfer, which include voice, video, audio and Internet protocol data (Triple Play services, i.e. High Speed Internet, Broadcast TV, VoIP). Method comprises forming a database of content units to the user or user group, which formed a particular list. On a basis of list make more precise calculation of the required bandwidth in the system by building a queue of orders for the reservation rate for each ordered content unit for each user or user group. Combine the same orders and multicasting of the same custom content units to the user or user group. Carry out the automatic switching user access device (e.g. Set Top Box) on a content channel that has broadcast content unit in accordance with his request. Also carry out the distribution of channel resources through the creation of dynamic content feeds that include content-length T units to be transferred to user groups at certain intervals. Usage of described method for allocating channel resources in a broadband access system during data transfer including multi-media data is notably effective for high-speed broadband wireless access systems, for example-networks like LTE or BARS, etc. with limited resources of data transfer environment, as was described above, and allows to raise optimization of broadband access channel resources, to raise grade of interactivity when providing multiservice data transfer, Triple Play services in particular, especially IPTV services and also essentially reduce expenses for forming of content-unit lists for distribution, as it is done according to analogues (closest prior art) from level of technics.
