Method and system for determining mapping relationship between multicast broadcast single frequency network area and service area
First Claim
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.

Abstract
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.

9. A system for determining a mapping relation between an MBSFN area and a service area, comprising:
-
a receiving module for receiving an M2 setup request message sent by an eNB, wherein MBMS area information of each cell is carried; and a mapping relation message sending device for allocating the MBSFN area identities and sending a message with a mapping relation between the MBSFN area and the service area to the eNB, wherein the eNB stores the mapping relation until MCCH configuration information is received so as to perform subsequent operations with air interfaces if the MCCH configuration information is not included in the message. - View Dependent Claims (10, 11, 12, 13, 14)

15. A system for determining a mapping relation between an MBSFN area and a service area, comprising:
-
an M2 setup request message sending device which is positioned in an eNB and used for sending an M2 setup request message to an MCE, wherein MBMS area information of each cell is carried; and an acquiring device which is positioned in the eNB and used for receiving a message with the mapping relation between the MBSFN area and the service area sent by the MCE and acquiring the mapping relation between the MBSFN area and the service area, wherein the eNB stores the mapping relation until MCCH configuration information is received so as to perform subsequent operations with air interfaces if the MCCH configuration information is not included in the message. - View Dependent Claims (16)
