Abstract: This application provides an IAB node mobility management method and a related device. If an IAB node encounters an unpermitted area, the method provides a solution in which access of an JAB-MT is allowed but an IAB-DU is not activated. This is conducive to rapid recovery of communication after the IAB node moves out of the unpermitted area while satisfying an unpermitted area constraint. This application can support setting of an unpermitted area that is less than a cell granularity and that is related to a cell, and can also be compatible with setting of an unpermitted area that is greater than or equal to a cell granularity or that is unrelated to a cell.

Abstract: This application provides a communication method and an apparatus. The method includes: A first node located in a first cell obtains a first correspondence between a cell provided by the first node and tracking area information, where the first correspondence is related to tracking area information corresponding to the first cell. When migrating from the first cell to a second cell, the first node obtains a second correspondence between the cell provided by the first node and tracking area information, where the second correspondence is related to tracking area information corresponding to the second cell.
