Abstract:
1. A method for determining a mapping relation between a multicast broadcast single frequency network (MBSFN) area and a service area comprising the steps of: receiving, by a multicast coordination entity (MCE), an M2 setup request message sent by an eNB, wherein MBMS area information of each cell is carried; and allocating, by the MCE, MBSFN area identities and sending a message with the mapping relation between the MBSFN area and a service area to the eNB so that the eNB can acquire the mapping relation between the MBSFN area and the service area, wherein the MCE sends the message with the mapping relation between the MBSFN area and the service area to the eNB at the same time of transmitting the MBSFN area identities; and wherein, if multicast control channel (MCCH) configuration information is not included in the message, the eNB stores the mapping relation until the MCCH configuration information is received so as to perform subsequent operations with air interfaces.
