The present invention discloses a multi-access method for underwater mobile gateways with multi-domain joint processing, comprising a remote guidance phase, a short-range channel sensing phase, and a short-range data transmission phase. During the remote guidance phase, a user node that needs to transmit data first sends an RTS signal to a gateway node. Upon receiving the signal, if the gateway node is idle, it replies with a CTS signal to the user node. Simultaneously, the gateway node can preliminarily determine the user node's location based on the received RTS signal energy and the direction of arrival, and then move toward the user node based on this location. The present invention optimizes the multi-access protocol from the perspective of multi-domain joint processing, combining time and space dimensional information. This allows nodes closest to the gateway node but with a slightly later access time to transmit data first, without excessively delaying the data transmission needs of other users. This reduces the total distance the gateway node needs to travel during data recovery, thereby improving multi-user transmission efficiency.
