The switching condition may be a condition that a certain IAB donor is switched to a master IAB donor. Since the splitting manner of the main IAB donor to each IAB donor of the target data is determined according to the data type of the target data and the configuration data of each IAB donor, it may be determined whether or not the IAB donor satisfies the switching condition for switching to the main IAB donor according to the statistical data. For example: when the statistical data of a certain IAB donor is higher than the statistical data of the current main IAB donor, and the configuration data such as bandwidth configuration, hierarchy configuration and the like are better than the configuration data of the current main IAB donor, determining that the IAB donor meets the switching condition of switching to the main IAB donor.

In an embodiment, the multiple of the target data distribution flow sending speed may be preset according to the configuration parameter of the current main IAB donor, and if the sending speed of a certain IAB donor for the received target data distribution flow is far greater than the preset multiple, it is indicated that the configuration parameter of the IAB donor is higher than the configuration parameter of the current main IAB donor, that is, the IAB donor has better computing and data distribution capabilities. Therefore, the target data distribution down-flow speed of each IAB donor can be determined according to the statistical data, and if the distribution down-flow speed of other IAB donor exceeds the preset multiple of the current main IAB donor distribution down-flow speed, it is determined that the IAB donor meets the switching condition of switching to the main IAB donor.
