A method (300) of a network node for delivering a plurality of simultaneous sessions to a client via a Radio Access Network (RAN) is provided. The method comprises identifying (301) a streaming session, reshaping (302) the streaming session into a sequence of bursts and silent periods, identifying (303) at least one non-time-critical session, reshaping (304) the at least one non-time-critical session into respective sequences of bursts and silent periods, and transmitting (305) the sequences of bursts and silent periods to the RAN. The reshaping (304) of the non-time-critical sessions is performed such that bursts, or silent periods, or both, of the at least one non-time-critical session are aligned with bursts, silent periods, or both, respectively, of the streaming session. By timely aligning the respective bursts and silent periods with each other, the duration of common silent periods may be increased, thereby utilizing air interface resources more efficiently. In addition, a method of a client for receiving a plurality of simultaneous sessions via a RAN is provided.
