1. A cell reconfiguration method performed by a mobile integrated access backhaul (IAB) node, comprising:
receiving reconfiguration information of a first cell; and
performing a cell reconfiguration operation according to the reconfiguration information, wherein the performing a cell reconfiguration operation comprises:
configuring a second cell as a secondary cell or a primary secondary cell of a terminal, and establishing a connection between the second cell and the terminal, wherein the second cell is a new cell created by the mobile IAB node, and the terminal is a terminal that provides services to the first cell; and
releasing the first cell;
wherein in a case that the first cell is a secondary cell, the performing a cell reconfiguration operation comprises:
releasing the first cell; and
creating a new cell as the second cell on a carrier of the first cell, and configuring the second cell as a secondary cell of the terminal;
activating the second cell.
