Abstract
An intelligent assisted transmission method is provided. In the method, a Multicast and Broadcast Service (MCBCS) Server transmits Multicast Broadcast Service (MBS) data to a base station in an MBS area. The base station transmits the MBS data to a user equipment. If the user equipment cannot correctly receive the MBS data, it returns a Not Acknowledgement (NACK) message to the base station. The base station transmits an intelligent assisted transmission prompt to the MCBCS Server. The MCBCS Server transmits an intelligent assisted transmission request to adjacent base stations of the base station. When the intelligent assisted transmission request is received, the adjacent base stations return an intelligent assisted transmission response. The MCBCS Server transmits the MBS data to the adjacent base stations, and the adjacent base stations transmit the MBS data to the user equipment.
