Abstract: A bandwidth configuration method and a related device are disclosed. An electronic device first determines bandwidth configuration schemes of N AP groups, and then adjusts the bandwidth configuration scheme of the AP group based on a physical topology similarity between the AP groups. When physical topologies of two AP groups are similar, if bandwidths of two APs at corresponding physical locations in the two AP groups are different, the electronic device determines a larger value of the bandwidths of the two APs as the bandwidths of the two APs.

Abstract: This application provides a coverage hole detection method and a related device in the field of communication technologies. If a coverage hole exists between two access point (APs), a terminal passes through the coverage hole when roaming between the two APs. Therefore, a roaming behavior of the terminal between the APs can reflect whether the coverage hole exists between the APs. An electronic device determines, based on a roaming behavior of a terminal between a first AP and a second AP, that a coverage hole exists between the first AP and the second AP. The roaming behavior of the terminal between the first AP and the second AP includes roaming behaviors of a plurality of terminals between the first AP and the second AP.

Abstract: This application discloses a roaming steering method, an apparatus, a device, a storage medium, and a system. In this application, a reference roaming steering condition is determined by an access control device by performing, for a plurality of times, a roaming steering test on one or more terminals belonging to a reference model, and the reference model is a model of a target terminal. Therefore, the reference roaming steering condition is similar to a roaming rule in the target terminal. In this case, when a first access point device obtains the reference roaming steering condition and determines that the target terminal satisfies the reference roaming steering condition, even if the target terminal does not unconditionally obey roaming steering of the first access point device, there is a high probability that the target terminal is successfully steered to roam.
