Abstract
The present invention discloses a method and a device for transmitting multimedia broadcast multicast service control information. The method comprises: a base station stopping transmission of an MBMS service in a cell, and transmitting control plane information of the MBMS service, wherein, in the control plane information, contents of an SIB2, MCCH information and DSI remain unmodified, and contents of an SIB13 are modified or remain unmodified. The device comprises: a service stopping unit, configured to stop transmission of an MBMS service in a cell; a transmitting unit, configured to transmit control plane information of the MBMS service in the cell in which the MBMS service is stopped, wherein in the transmitted control plane information, contents of an SIB2, MCCH information and DSI remain unmodified, and contents of an SIB13 are modified or remain unmodified. The present invention improves reliability of receiving an MBMS service by a UE.
