Abstract: It is provided a method for allocating a plurality of multimedia broadcast and multicast service, MBMS, sessions, the method being performed in one of a plurality of network nodes of an MBMS single frequency network. The method comprises the steps of: receiving an MBMS session event for one of the plurality of MBMS sessions; calculating a number of subframes needed within an allocation period to transmit the plurality of MBMS sessions of the single frequency network based on a guaranteed bitrate and quality of service, QoS, associated with each one of the MBMS sessions and a modulation and coding scheme, MCS, that is set for each QoS; determining a subframe pattern for the subframes within the allocation period; allocating the plurality of sessions within the subframe pattern according to a predetermined order, based on a guaranteed bitrate and; and transmitting a result of the allocating.
