Abstract
A method for supporting Multicast Broadcast Multimedia Service (MBMS) data transmission in a Long-term evolution (LTE) system includes a network entity (ECN) to which a user equipment (UE) is registered, receives an Activate MBMS context request message from the UE, and sends a Create MBMS UE Context Request message to a ECN that offers MBMS service. The ECN that offers MBMS service performs an authorization process with a Broadcast and Multicast Service Center (BM-SC) and sends a 'Create MBMS UE Context Response' message to the ECN to which the UE is registered. The ECN to which the UE is registered sends an Activate MBMS Context Accept message to the UE. With the methods for supporting the transmission of MBMS data in the LTE system according to present invention, both the BM-SC and the ECN can find the downstream node so that service transmission paths may be found for MBMS data.
