Abstract
An MBMS providing apparatus and an MBMS providing method using the same in a cloud radio access network are provided. The MBMS providing apparatus includes a third layer into which a plurality of network layers providing an MBMS are integrated in the plurality of DUs, and a second layer into which a plurality of datalink layers providing the MBMS are integrated in the DUs. Therefore, the present invention integrates the layers that provide the MBMS in the plurality of DUs, and provide the MBMS by MBSFN synchronization area through the integrated layers. Accordingly, by performing the MBMS by MBSFN synchronization area through respective integrated layers, the present invention can prevent the occurrence of an unnecessary load, thus enhancing the performance of a communication network.
