The invention provides a beam guiding method, a satellite load, a satellite and a communication system, and the method comprises the steps: broadcasting a signaling spot beam to all terminals in a coverage area, then receiving access request information returned by a plurality of terminals in response to the signaling spot beam, determining the positions of the plurality of terminals according to the access request information, and transmitting the positions of the plurality of terminals to a server. And then configuring a service spot beam to point to the positions of the plurality of terminals in a beam hopping manner, so that service data is transmitted between the satellite and one or more terminals with the same beam position in one time slot of the service spot beam. Thus, the service spot beam is guided by the signaling spot beam, and the spot beam is narrow in beam and high in gain, so that the problem that the capacity of the access signaling is limited can be solved, and the number of access users i
