The present invention discloses a method and system for determining a mapping relation between the MBSFN area and the service area, wherein the method includes: an eNB sends an M2 setup request message to an MCE; the MCE allocates MBSFN area identities and sends a message with a mapping relation between the MBSFN area and the service area to the eNB; and the eNB acquires the mapping relation between the MBSFN area and the service. By the technical scheme of the invention, the mapping relation between the MBSFN area and the MBMS area can be defined, thus ensuring the synchronization transmission demand of the MBSFN with air interfaces.
