Method, system and equipment for realizing synchronization of multicast/broadcast service (MBS) of multi-hop system

The invention discloses a method, a system and equipment for realizing the synchronization of a multicast/broadcast service (MBS) of a multi-hop system, which belong to the field of communication. In the multi-hop system of a plurality of cells, the method comprises the following steps: acquiring a maximum processing delay of the cells by base stations of each cell; reporting the acquired maximumprocessing delay to an MBS gateway; receiving an MBS transmitting time transmitted by the MBS gateway; and transmitting an MBS data packet to each of relay branches of the base stations according to the MBS transmitting time. The system comprises the MBS gateway, the base stations and the relay branches. The equipment comprises the MBS gateway, the base stations and a relay. The method, the system and the equipment fully take the processing delays of each cell into consideration, thereby ensuring that the MBS data packet can be prepared in advance when the MBS of each stage of stations are initiated, enabling the MBS
