    determining, by the controller based on the IN-PDN distribution information, whether a second UE and a second user plane gateway exist, wherein there is a mapping relationship between the second UE and the first IN-PDN, a mapping relationship between the second UE and the first user plane gateway, and a mapping relationship between the second user plane gateway and the first IN-PDN; and

    determining, by the controller based on a determining result about whether the second UE and the second user plane gateway exist, whether to update a mapping relationship between the first IN-PDN and a forwarding tunnel, a mapping relationship between the first IN-PDN and the first UE, and a mapping relationship between the first IN-PDN and the first user plane gateway.
