A configuration method and an indication method of MBSFN frames and an identifying method used by a terminal applied in a long term evolution system are disclosed in the present invention, which include: an access network sends configuration parameters of the MBSFN frame to a mobile terminal determining whether the wireless frame received is an MBSFN frame according to the configuration parameters, the configuration parameters including a repetition period of the MBSFN frames distributed in system-set time. With the present invention, it could consume less bytes in system message to complete the configuration of the MBSFN sub-frames and could save system resources.
