FIELD: physics, communications.
SUBSTANCE: invention relates to resource delivery in a digital communication system. The result is achieved due to that during reception of files in a file delivery session, where field descriptor tables (FDT) identify transport objects (TO) transmitted together with the FDT, a receiver determines, through several timers, whether files of that delivery session were received. Fragment waiting time t1 is launched for each new transport object declared in the FDT when that FDT is received. Each timer is stopped when at least one fragment of the corresponding transport object is received. Alternatively, a single timer is stopped when at least one fragment of the entire transport object is received. A new object waiting timer t3 is launched when all transport objects declared in the FDT are received and stopped when a new FDT is received. One of several table waiting timers t2 is launched each time a transport object not indicated in any received FDT is received, and stopped when an FDT in which this object is declared is received.
EFFECT: managing change to set of files during a communication session.
