Patent number: 10264494Abstract: Provided are a method and device for sending indication information, and UE. In the method, a UE sends to a network side, when determining that the UE has left an MBSFN area capable of carrying a predetermined MBMS, indication information for triggering the network side to set up a bearer for the UE to transmit the predetermined MBMS. The technical problem in the related art that a network side usually fails to know that UE moves to a cell unable to carry an MBMS, so that the network side cannot ensure service continuity and thus reception of the MBMS by a user side is interrupted is solved. The network side knows in time that the UE has left the MBSFN area capable of carrying the predetermined MBMS that is being received or is prepared to be received, and the network side can take measures in time to ensure MBMS continuity.Type: GrantFiled: June 16, 2014Date of Patent: April 16, 2019Assignee: XI'AN ZHONGXING NEW SOFTWARE CO., LTD.Inventors: Zijiang Ma, Hongjun Liu, Chen Lu
