FIELD: radio engineering, communication.SUBSTANCE: invention involves use of additional capacity provided by MBMS based on a single-frequency network (MBSFN) in order to transmit a higher quality or more robust versions of MBMS services. The broadcast multicast service centre (BM-SC) provides the same MBMS user service in two versions, one for the regular MBMS and the other for MBSFN. The MBSFN version of the service may be charged differently and may need to be protected separately. In various versions of the invention, the user equipment is informed that the same service is present in multiple versions and therefore can select one of the available versions for use.EFFECT: optimising network load.24 cl, 7 dwg |
